  •                IN THE SUPREME COURT OF IOWA
    No. 15–0574
    Filed June 23, 2017
    TINA HASKENHOFF,
    Appellee,
    vs.
    HOMELAND ENERGY SOLUTIONS, LLC,
    Appellant.
    Appeal from the Iowa District Court for Chickasaw County, John J.
    Bauercamper, Judge.
    Employer appeals judgment on jury verdict for plaintiff on claims
    for sexual harassment and retaliation. DISTRICT COURT JUDGMENT
    REVERSED AND CASE REMANDED FOR NEW TRIAL.
    Kevin J. Visser and Lisa A. Stephenson of Simmons Perrine Moyer
    Bergman PLC, Cedar Rapids, for appellant.
    Roxanne Barton Conlin of Roxanne Conlin & Associates, P.C.,
    Des Moines, and Brooke Timmer and Paige Fiedler of Fiedler & Timmer,
    P.L.L.C., Johnston, for appellee.
    2
    WATERMAN, Justice.
    In this appeal, we must decide whether the district court correctly
    denied an employer’s motion for new trial following a $1.4 million jury
    verdict for the plaintiff on claims under the Iowa Civil Rights Act (ICRA)
    for employment discrimination based on sexual harassment by a direct
    supervisor and coemployees.      The employer argues the district court
    erred by submitting a direct negligence claim instead of vicarious liability
    for supervisor harassment and misinstructed the jury on the elements of
    proof, the causation standard for retaliation, the definition of adverse
    employment action, and constructive discharge.         The employer also
    argues a new trial is required for attorney misconduct, errors in allowing
    expert testimony on legal standards, and excessive damages, which
    included $1 million for future emotional distress. Finally, the employer
    argues the district court erred by awarding excessive attorney fees of
    $846,364, the full amount claimed.
    For the reasons explained below, we hold that workers may bring a
    direct-liability negligence claim under the ICRA against the employer for
    supervisor harassment, but the plaintiff must prove the employer knew
    or should have known of the harassment and failed to take prompt and
    appropriate remedial action to end it.       We conclude that prejudicial
    errors in four jury instructions require a new trial. We find no abuse of
    discretion in the admission of the expert testimony. We need not decide
    the remaining issues raised in the appeal.
    I. Background Facts and Proceedings.
    The jury could find the following facts based on the record
    developed at trial. Homeland Energy Solutions, LLC (HES) operated an
    ethanol plant with forty-five employees in Lawler, Iowa. On February 16,
    2009, HES hired Tina Haskenhoff as a lab manager at the plant. That
    3
    day, she was provided with a copy of the HES employee handbook, which
    included its policy on sexual harassment.           The policy stated sexual
    harassment was prohibited and provided that “[a]n employee who
    believes he or she has been subject to harassment prohibited by this
    policy should report the incident immediately to their supervisor or a
    member of the Management Team.” The policy stated any complaint of
    sexual harassment would be investigated and any employee may bring a
    complaint “without fear of reprisal.”
    Haskenhoff was repeatedly harassed by her immediate supervisor,
    Kevin Howes, HES’s operations manager.               Howes repeatedly made
    inappropriate comments in Haskenhoff’s presence. For example, Howes
    talked about Haskenhoff’s breasts on at least three occasions, referring
    to them as “them puppies” or “the twins.” Howes discussed Haskenhoff’s
    body and attire with other employees and speculated out loud about
    what it would be like to have sex with her. He insinuated to other male
    employees that they could get Tina into bed.              He commented on the
    attractiveness   or   unattractiveness      of   female    job   applicants   and
    employees. He spoke at work about strippers. On multiple occasions, he
    used objects or engaged in body motions in front of Haskenhoff to
    simulate sexual behavior.
    Haskenhoff’s coemployees also engaged in inappropriate conduct
    in her presence. One displayed a screen saver on his computer of two
    young girls touching tongues.           Another photographed Haskenhoff’s
    cleavage at a company outing and showed that photo to others.
    Haskenhoff received an unwanted pornographic video from yet another
    employee.   The atmosphere Haskenhoff experienced at the HES plant
    was unseemly and unprofessional.
    4
    In November 2010, Haskenhoff told Howes she needed to leave
    work early for a mammogram.             She remembered Howes responding,
    “[W]ell, you know, if you sat out in the parking lot you could probably
    make some money.” She interpreted this to mean, “[I]f I sat in my car
    and put a sign up guys would pay to grope me.” Howes’s recollection
    differed; he recalled he told Haskenhoff she “could go around the corner
    and use the copying machine and save herself some money.” He stated
    that he meant Haskenhoff could “[u]se the copying machine, make a
    photocopy    [of     her   breast]   versus   going   to   the   doctor.”   Howes
    acknowledged that his comment was inappropriate. Haskenhoff reported
    the incident to the plant manager, Chad Kuhlers.             Kuhlers forwarded
    Haskenhoff’s report to the head of human resources, Sarah Frein. The
    next day, Howes came to Haskenhoff’s office and spoke with her.               He
    apologized for his comment and expressed concern that Kuhlers wanted
    him fired because of it.        Haskenhoff said Howes made her feel “very
    intimidated.” Shortly after her interaction with Howes, Walter Wendland,
    the chief executive officer (CEO) of HES, asked Haskenhoff to come to his
    office. She recalled at this meeting,
    [Wendland] said—he was kind of, like, well, what’s going on
    here, and he said you know Chad [Kuhlers] really wants me
    to fire Kevin over this, and I said I never asked Chad to fire
    him. And then Walt went on to say, well, come [on]. I
    thought we were like a family. You don’t want to do this to
    your family.
    On December 7, Frein called Haskenhoff into her office to discuss her
    complaint. Jeff Grober, the chief financial officer (CFO), was also present
    in Frein’s office.    At that meeting, Frein’s notes indicate that she had
    planned “further discussion” about the complaint, but Haskenhoff stated
    she did not want the investigation to go further because she did not want
    Howes to be fired. Haskenhoff later testified about that meeting:
    5
    Q. And what happened in that meeting? A. They
    asked me about it. She said that Chad had notified her of
    something Kevin had said to me that I reported as making
    me uncomfortable, and I said he did. And I think I broke
    down at that point, and I said I don’t want him to get fired
    over this, you know. I said to her I’m sure now that he
    knows, now that it has been pointed out to him, surely he
    will stop. Anybody would stop.
    Q. Is that what you believed would happen? A. Yes.
    Q. Did you tell ’em you wanted it dropped? A. I said
    if it were going to come to the point of Kevin getting fired, I
    didn’t want to go—I didn’t want to officially go further at all
    because I did not want him fired over that.
    Q. Did you want them to do something about it?
    A. Yes.
    At Haskenhoff’s request, Frein took no further disciplinary action against
    Howes at that time.
    Wendlend later removed Kuhlers as plant manager and promoted
    Howes to that position. For the next nine months, Haskenhoff made no
    complaints to management about Howes.         Her performance review in
    January 2011 noted that she met or exceeded requirements in all areas.
    However, the review also noted that Haskenhoff had areas to work on
    and referenced an email dispute in which Haskenhoff had become
    argumentative with a subordinate over lab procedures.         In May, she
    began seeking a position at John Deere.
    On August 8, Haskenhoff walked by Howes’s office and overheard
    him talking on his cell phone. Haskenhoff recently had told Howes she
    intended to marry her long-time boyfriend. Haskenhoff overheard Howes
    say, “Yep, she’s getting married.    And for a good reason (pause) for
    money.” This comment upset Haskenhoff. She walked into the control
    room and told another employee, “Okay. Kevin is a [f&#%!@”g] asshole. I
    am leaving. I will be back tomorrow.” Haskenhoff left work at 11:15 that
    morning.
    6
    Haskenhoff sent an email to Howes expressing her disgust at his
    comment. Howes replied that he had not meant to offend her and asked
    her to meet the next day in his office to discuss the issue. Later that
    night, Howes sent an email to the CEO, Wendland; the CFO, then David
    Finke; and the commodities manager, Steve Wubbena.         In the email,
    Howes said he wanted to discipline Haskenhoff for calling him expletives
    in front of subordinate employees, for leaving the lab a mess, and for
    leaving work without permission for the day. He pointed out Haskenhoff
    had been the only lab person scheduled, lab samples had not been
    completed, they were in the middle of a lab trial, and she “blew off” a
    conference call by leaving.     Howes also expressed frustration at
    Haskenhoff’s attitude, her frequent smoke breaks, and her failure to
    arrange coverage for her shifts on her days off. Finke responded, “We
    claim that she does a lot of things poorly, do we have any of this
    documented and on file?”
    The next day, Haskenhoff met with Howes and Wubbena in
    Howes’s office.   They discussed the conduct from the day before, and
    Howes apologized. Howes also used the term “insubordination” to refer
    to Haskenhoff’s reaction to his comment.        Haskenhoff replied using
    terms such as “sexual harassment” and “hostile work environment” to
    refer to Howes’s conduct. She then told Howes about other conduct in
    the office, including about a coemployee having an inappropriate screen
    saver and inappropriate nicknames being used in the office.       Howes
    responded after their meeting by directing the employees to cease using
    the nicknames and to remove the screen saver.
    The following week, Frein emailed Haskenhoff asking for “facts,
    examples, and concerns [of inappropriate conduct] in writing so we can
    get them addressed appropriately.” Haskenhoff responded by email to
    7
    Frein the same day, listing multiple incidents of inappropriate conduct
    and stating the list was long “but not all encompassing.”       Haskenhoff
    said the only reason she brought the issues up was that Howes had
    threatened to write her up for insubordination.           Frein immediately
    forwarded this email to Finke, who responded, “I don’t think we can
    discount anything that is mentioned below.              Some of it may be
    embellished a bit, but we still cannot just take it with a grain of salt.”
    Finke stated that the first step was to look at the employee handbook,
    the second step was a plant-wide training for sexual harassment, and
    the third step was devising a plan to address the issue with Howes.
    The next day, Howes prepared a written warning for Haskenhoff’s
    conduct leaving work early. He also provided Frein with a statement of
    what occurred during the August 9 meeting.          Wubbena forwarded a
    statement to Frein as well. A day later, Finke emailed Frein recounting
    that he told Howes he needed to be “OVERLY” professional in “ALL” of his
    work-related endeavors moving forward. Finke’s email also told Frein,
    “In the meantime, I want you to be thinking about forming a game plan
    for investigation [of] Tina’s claims.”   Frein enlisted the help of outside
    counsel, James Gilliam, that day. Frein asked Gilliam questions about
    HES’s next steps, including whether Haskenhoff could be disciplined for
    leaving work early without permission and for “plotting” against Howes.
    HES    investigated    Haskenhoff’s    complaint     by   interviewing
    employees, including Haskenhoff and Howes.              During Haskenhoff’s
    interview on August 23, Wendlend and Frein were present and reviewed
    Haskenhoff’s list of incidents.      As to several incidents, Wendlend
    commented to Haskenhoff that the conduct did not violate the company’s
    policy and crossed them off the list in her presence.
    8
    While the investigation was ongoing, Howes began drafting staff-
    counseling forms, or write-ups, for what he perceived as Haskenhoff’s
    insubordination leaving the plant early on August 8. Howes indicated he
    wanted to terminate Haskenhoff and contacted other employees to gather
    more evidence of her insubordination. Howes also repeatedly reminded
    other employees to keep work professional and informed them of
    upcoming    mandatory    harassment     training.    Gilliam   and     Frein
    recommended that Haskenhoff not be disciplined for her conduct
    because “the timing was inappropriate.” Finke told Howes by email that
    he did not feel comfortable terminating Haskenhoff, stating,
    I honestly feel that Walt and I are getting to the bottom of a
    very serious situation and that we are doing it in the proper
    manner. For me, the end goal is to make an informed proper
    conclusion per Homeland’s policies and under the guidance
    of qualified legal counsel.
    Nevertheless, Howes drafted two final staff-counseling forms regarding
    Haskenhoff, one entitled “#3” and the other “#4.” He emailed these forms
    to Wendland and Finke. Form #3 discussed the investigation and listed
    the “numerous harassment/inappropriate behavior claims” as one of the
    reasons for disciplining Haskenhoff.     Form #4 did not mention the
    investigation and focused on Haskenhoff’s conduct on August 8 leaving
    work without permission. Howes said he liked #4 because “it does not
    come across as being retaliatory in nature.” Both forms recommended
    giving Haskenhoff a written warning and ninety-day performance
    improvement plan.
    On August 29, Wendland and Finke presented Howes with a
    written staff-counseling form, which determined that Howes had “made
    unprofessional and unacceptable comments in the workplace.” It stated
    that HES expected Howes’s conduct to improve and that if it did not, he
    9
    would be subject to disciplinary action, including possible discharge.
    Two days later, Wendlend and Finke met with Haskenhoff to discuss the
    results of the investigation.        They assured her that she would not be
    retaliated against and directed her to report any perceived retaliation to
    Finke or Wendland. Then, while Wendlend and Finke were still present,
    Howes entered the room and presented Haskenhoff with a draft
    performance improvement plan addressing her conduct on August 8.
    Haskenhoff disagreed with many allegations in the plan.                      The men
    assured her the plan would be redrafted to reflect her concerns.                    The
    next day, Haskenhoff reported to HES for work. At around 11 a.m., she
    entered Finke’s office and resigned, calling the previous day’s events
    “bullshit.” 1 Six weeks later, Haskenhoff began working at John Deere.
    Haskenhoff filed an administrative complaint with the ICRA eight
    months later. After receiving an administrative release, Haskenhoff filed
    a civil action in Chickasaw County District Court, alleging sexual
    harassment and retaliation under the ICRA. The jury trial commenced
    on October 1, 2014, and spanned three weeks.
    HES filed multiple motions in limine, several of which were granted
    by the district court. An order in limine prohibited Haskenhoff’s counsel
    from making any reference to “rape,” “sexual assault,” or similarly
    inflammatory terms and expressly prohibited making any analogy
    between rape and the harassment complaint.                     Despite that ruling,
    Haskenhoff’s counsel, during her examination of HES’s CEO at the jury
    trial, asked this question:
    1Haskenhoff   posted on social media two days later to a friend, “[J]ust wanted to
    let you know that [I] quit Homeland yesterday without giving any notice, had enough of
    Kevin’s bullshit vulgarity and juvenile behavior and favoritism . . . followed your lead
    LOL[.]”
    10
    Q. I mean, don’t you think it would be analogous, for
    instance, if someone had accused someone of rape and then
    the person they accused of rape was able to walk in and say
    that’s defamation for saying I’m a rapist?
    MR. VISSER: Objection; this is argument,            it’s
    improper, and violates the terms of pretrial orders.
    THE COURT: Sustained as to argumentative.
    Another order in limine forbade Haskenhoff’s counsel from offering
    testimony about Howes’s character or referring to him as “juvenile,
    immature, chauvinistic, vindictive, holding a grudge, or capable of
    retaliation,” as such evidence was not probative of truthfulness. Counsel
    for Haskenhoff nevertheless asked the following questions in front of the
    jury:
    Q. [To Matthew Dutka, employee of HES] And based
    on knowing and observing [Howes], is he the kind of person
    that would be likely to use people to get what he wants?
    ....
    Q. [To Wade Heideman, employee of HES] Based on
    your observations about Kevin, would he be the kind of guy
    who would hold a grudge?
    ....
    Q. [To Sherri Hansen, employee of HES] From your
    time working with Mr. Howes, do you think he would have
    done everything in his power to get rid of Tina?
    Counsel for HES objected over 574 times during the trial, according to
    Haskenhoff.    The court sustained 353 defense objections, or sixty-one
    percent. By contrast, counsel for Haskenhoff objected fifty-nine times,
    thirty of which were sustained (fifty-one percent).
    The district court denied HES’s motion in limine to exclude the
    testimony of expert witness Dr. Louise Fitzgerald, professor emeritus of
    the University of Illinois at Urbana-Champaign, who taught Psychology
    and Gender and Women’s Studies. HES argued her testimony included
    inadmissible legal conclusions.      Dr. Fitzgerald testified over defense
    11
    objections about the standard of care in the human resources field for
    policies and procedures regarding sexual harassment and HES’s alleged
    failure to meet that standard. She also testified about victims’ typical
    reactions to sexual harassment and stated Haskenhoff displayed those
    reactions.   HES argues the jury instructions were shaped to reflect
    Dr. Fitzgerald’s testimony. At the close of evidence, the parties made a
    record on jury instructions.
    A. Direct Negligence Versus Vicarious Liability for Supervisor
    Harassment. HES requested an instruction on sexual harassment that
    applied different standards of liability depending on the harasser’s
    position within the company.      For harassment by a coworker, HES’s
    proposed instruction stated it would be liable if it “knew or should have
    known of the abusive or hostile conduct and failed to take prompt and
    corrective action to end the harassment.”         If the harasser was a
    supervisor, HES’s proposed instruction did not require the plaintiff to
    prove HES knew or should have known of the harassment, but allowed
    HES to prove, as an affirmative defense, that it “exercised reasonable
    care to prevent and correct promptly any sexually harassing behavior”
    and that Haskenhoff “unreasonably failed to take advantage of any
    preventative or corrective opportunities provided by Homeland Energy
    Solutions or to avoid harm otherwise.” This is commonly known as the
    Faragher–Ellerth defense to employer liability.   See Faragher v. City of
    Boca Raton, 
    524 U.S. 775
    , 807, 
    118 S. Ct. 2275
    , 2293 (1998); Burlington
    Indus., Inc. v. Ellerth, 
    524 U.S. 742
    , 765, 
    118 S. Ct. 2257
    , 2270 (1998).
    Haskenhoff argued for a single marshaling instruction on a direct
    negligence theory that encompassed harassment by a supervisor or
    coworker.    The district court agreed and gave an instruction nearly
    12
    identical to Haskenhoff’s proposed instruction. The court’s marshaling
    instruction stated,
    INSTRUCTION NO. 14
    COUNT I – SEXUAL HARASSMENT CLAIM
    In order to recover damages on her claim of sexual
    harassment, the plaintiff, Tina Haskenhoff, must prove all of
    the following elements of her claim:
    1. The plaintiff, Tina Haskenhoff, was subjected to
    offensive conduct by employees, agents, or officers of
    Homeland Energy Solutions, L.L.C. while employed at its
    ethanol plant.
    2. Such conduct was unwelcome.
    3. Tina Haskenhoff’s sex played a part in such
    conduct.
    4. This conduct was sufficiently severe or pervasive
    that a reasonable person in Tina Haskenhoff’s position
    would find her work environment was hostile or offensive.
    5. At the time this conduct occurred and as a result of
    this conduct, Tina Haskenhoff believed that the work
    environment was hostile or abusive.
    6. Homeland Energy Solutions, L.L.C., knew or should
    have known of the occurrence of one or more sexually
    harassing incidents.
    7. Homeland    Energy  Solutions, L.L.C.  acted
    negligently in creating or continuing a hostile work
    environment.
    If you find that the plaintiff, Tina Haskenhoff, has
    failed to prove any of these propositions, the plaintiff is not
    entitled to damages on her claim of sexual harassment. If
    the plaintiff has proved all of these propositions, the plaintiff
    is entitled to damages in some amount.
    HES objected to this marshaling instruction, citing Farmland
    Foods, Inc. v. Dubuque Human Rights Commission, on liability for sexual
    harassment and the applicability of the Faragher–Ellerth defense. 
    672 N.W.2d 733
    , 744 (Iowa 2003).       HES also objected that the negligence
    standard had been incorrectly defined, stating, “Again, to the extent that
    there is co-worker harassment, the standard—the element is knew or
    13
    should have known and failed to take appropriate and prompt remedial
    action”—an element of proof was missing from the court’s instruction.
    B. Retaliation Instruction—Causation.         HES objected to the
    court’s marshaling instruction on Count II, retaliation. HES requested
    an instruction that required Haskenhoff to prove the protected activity
    was a “significant factor” motivating the adverse employment action. In
    contrast, Haskenhoff’s proposed instruction, which the district court in
    large part adopted, provided that the protected activity need only have
    “played a part” in defendant’s decision to take the adverse action. The
    court’s marshaling instruction stated,
    INSTRUCTION NO. 26
    COUNT II – RETALIATION CLAIM
    In order to recover damages on her claim of retaliation,
    the plaintiff, Tina Haskenhoff, must prove all of the following
    elements of her claim:
    1. The plaintiff, Tina Haskenhoff, engaged in protected
    activity by complaining about sexual harassment.
    2. The defendant, Homeland Energy Solutions, L.L.C.,
    took adverse action against Tina Haskenhoff.
    3. The protected activity played a part in Homeland
    Energy Solutions, L.L.C’s decision to take the adverse action.
    Instruction No. 28 elaborated,
    INSTRUCTION NO. 28
    FACTOR – DEFINED
    The plaintiff’s harassment complaints played a part in
    her treatment if those complaints were a factor in the
    defendant’s employment actions toward her. However, her
    harassment complaints need not have been the only reason
    for the defendant’s actions.
    HES objected to these instructions, stating that the elements of a
    retaliation claim, as set forth in our decisions, “all provide that . . .
    causal connection is satisfied by a showing that the protected activity
    was a significant factor motivating the adverse employment action.” HES
    14
    cited City of Hampton v. Iowa Civil Rights Commission, 
    554 N.W.2d 532
    ,
    535 (Iowa 1995), and Hulme v. Barrett, 
    480 N.W.2d 40
    , 42 (Iowa 1992).
    C. Adverse Action. HES also objected to the court’s instruction
    defining “adverse employment action.”     HES requested an instruction
    that defined an adverse employment action as
    an action that detrimentally affects the terms, conditions, or
    privileges of employment. Changes in duties or working
    conditions that cause no materially significant disadvantage
    to the employee are not adverse employment actions. It
    includes, but is not limited to, employment actions such as
    termination of an employee, failure to promote, or any action
    that would discourage a reasonable employee from making a
    complaint of harassment. Giving an employee a performance
    improvement plan or negative employment review is not
    “adverse employment action” unless they are later used as a
    basis to alter the employee’s terms or conditions of
    employment in a detrimental way. Both the action and its
    context must be examined.
    The district court declined to give HES’s proposed instruction and
    instead gave Haskenhoff’s instruction, which listed more activities as
    examples of adverse action:
    INSTRUCTION NO. 30
    ADVERSE ACTION – DEFINED
    “Adverse action” means any action which has material
    consequences to an employee. It is anything that might
    dissuade a reasonable person from making or supporting an
    allegation of discrimination or harassment.
    It includes but is not limited to, such employment
    actions as constructive discharge, reprimands or threats of
    reprimands, a change in opportunities, false accusations or
    complaints, being investigated, being placed on a
    performance improvement plan, being placed on probation,
    or other actions which adversely affect or undermine the
    position of the employee. It also includes an employer
    seeking out negative feedback on an employee, or condoning
    or encouraging other employees to complain about her. You
    should judge whether an action is sufficiently adverse from
    the point of view of a reasonable person in the plaintiff’s
    position.
    15
    HES objected, stating the second paragraph was “misleading and an
    incomplete statement of the law” because it included reprimands and
    other matters never found to constitute adverse action.       The court
    overruled the objection.
    D. Constructive      Discharge.   HES objected to the       court’s
    instruction on constructive discharge, which was adopted verbatim from
    Haskenhoff’s proposed instruction and stated,
    INSTRUCTION NO. 33
    CONSTRUCTIVE DISCHARGE – EXPLAINED
    An employee is constructively discharged if the
    employer deliberately makes her working conditions
    intolerable so that the employee reasonably feels forced to
    quit. The work environment need not literally be unbearable
    to be intolerable under the law. The employer need not
    really want the employee to quit. It is sufficient that the
    employee’s resignation was a reasonably foreseeable
    consequence of the working conditions created or permitted
    by the employer.
    The employee must show that she was subjected to
    sexual harassment or retaliation [that] made her believe
    there was no chance for fair treatment at Homeland.
    An employee does not need to stay as an employee if
    she reasonably believes there is no possibility the employer
    will treat her fairly. It is enough if the employee has no
    recourse within the employer’s organization or reasonably
    believes there is no chance for fair treatment.         The
    intolerable working conditions may be created by either the
    action or inaction of the employer.
    HES objected that the instruction was an “incomplete and misleading
    statement of the law” because it injected a subjective standard. HES also
    specifically objected to
    the court’s failure to include language as suggested by the
    defendant in its constructive discharge claim, including but
    not limited to a statement that “the employee has an
    obligation to be reasonable, not assume the worst and not
    jump to conclusions; conditions will not be considered
    intolerable unless the employer has been given reasonable
    chance to resolve the problem.”
    16
    E. The Court’s Ruling. Following argument on each of the jury
    instructions, the court provided, “Court will overrule all of the objections
    and exceptions to the instructions.      Court believes they’re appropriate
    based on the factual record and the law as the court views it.” The case
    proceeded to verdict.
    On October 23, the jury returned a verdict for Haskenhoff on both
    counts and awarded damages in the amount of $1,400,000—$100,000 in
    backpay, $300,000 in past emotional distress, and $1,000,000 in future
    emotional distress.
    HES moved for a new trial on grounds of (1) the instructional
    errors set forth above, (2) erroneous evidentiary rulings allowing
    Dr. Fitzgerald to testify as to legal conclusions, (3) misconduct by
    Haskenhoff’s counsel, and (4) excessive damages.        Haskenhoff filed a
    motion requesting attorney fees and expenses of $846,364 and equitable
    relief of frontpay of $240,000.
    The district court denied HES’s motion for new trial. Specifically,
    the court found, “Jury instructions were thoroughly briefed by counsel
    and discussed at length with the court both on and off the record.” The
    court also noted that nearly all of HES’s asserted evidentiary errors were
    based on issues already ruled upon by the court during HES’s motion for
    summary judgment and motions in limine.             The court found the
    attorneys’ conduct to be merely a product of zealous representation and
    damages were not excessive. The court awarded frontpay and attorney
    fees in the full amount requested and entered judgment for Haskenhoff
    for a total of $2,486,364.
    HES filed a timely notice of appeal based on the issues raised in its
    motion for new trial and excessive attorney fees. We retained the appeal.

    II. Standard of Review.
    “We review alleged errors in jury instructions for correction of
    errors at law.”   DeBoom v. Raining Rose, Inc., 
    772 N.W.2d 1
    , 5 (Iowa
    2009) (quoting Boyle v. Alum-Line, Inc., 
    710 N.W.2d 741
    , 748 (Iowa
    2006)).   Similarly, we review the district court’s refusal to give a
    requested jury instruction for correction of errors at law.     Alcala v.
    Marriott Int’l, Inc., 
    880 N.W.2d 699
    , 701 (Iowa 2016). “It is error for a
    court to refuse to give a requested instruction where it ‘correctly states
    the law, has application to the case, and is not stated elsewhere in the
    instructions.’ ” DeBoom, 772 N.W.2d at 5 (quoting Vaughan v. Must, Inc.,
    
    542 N.W.2d 533
    , 539 (Iowa 1996)). Instructional error “does not merit
    reversal unless it results in prejudice.”   Id. (quoting Wells v. Enter.
    Rent-A-Car Midwest, 
    690 N.W.2d 33
    , 36 (Iowa 2004)). Prejudicial error
    results when instructions materially misstate the law or have misled the
    jury. Id. Jury instructions must be considered “in their entirety” when
    assessing prejudice.   Id. (quoting Anderson v. Webster City Cmty. Sch.
    Dist., 
    620 N.W.2d 263
    , 265 (Iowa 2000)). “We assume prejudice unless
    the record affirmatively establishes that there was no prejudice.” Rivera
    v. Woodward Res. Ctr., 
    865 N.W.2d 887
    , 903 (Iowa 2015).
    “We review a trial court’s decision to admit or exclude expert
    testimony for an abuse of discretion.” Ranes v. Adams Labs., Inc., 
    778 N.W.2d 677
    , 685 (Iowa 2010). We reverse district court rulings on the
    admissibility of expert opinion testimony “only when the record shows
    ‘the court exercised [its] discretion on grounds or for reasons clearly
    untenable or to an extent clearly unreasonable.’ ”      Id. (alteration in
    original) (quoting State v. Maghee, 
    573 N.W.2d 1
    , 5 (Iowa 1997)).
    Grounds are untenable when they are unsupported by substantial
    evidence or based on an erroneous application of the law. Id.
    18
    III. Analysis.
    The first question we must decide is whether Haskenhoff could
    recover from HES on a direct negligence theory for harassment by her
    supervisor, Howes.           HES contends a supervisor-harassment action
    requires     a   vicarious     liability   theory   and   an   affirmative-defense
    instruction, while only a coworker-harassment action can be brought
    under a direct-liability negligence (direct negligence) theory. Haskenhoff
    contends a plaintiff may sue the employer under a direct negligence
    theory for both supervisor and coworker harassment. We hold employers
    can be held liable for supervisor harassment under the ICRA on a direct
    negligence theory. However, the plaintiff must prove the employer failed
    to take prompt and appropriate remedial action to end the harassment, a
    fighting factual issue at trial.       Because the district court’s marshaling
    instruction omitted that element, a new trial is required.
    We next address the three remaining instructional errors in turn.
    We conclude the jury was misinstructed on the causation element for
    retaliation, on the definition of adverse employment action, and on
    constructive discharge.          These prejudicial instructional errors also
    require a new trial.         Finally, because the issue is likely to recur on
    remand, we address the admissibility of Dr. Fitzgerald’s testimony and
    conclude the district court did not abuse its discretion by allowing her
    testimony.
    A. Does the ICRA Allow a Plaintiff to Bring a Direct Negligence
    Claim Against the Employer for Supervisor Harassment? The parties
    agree that a plaintiff may sue an employer under a vicarious liability
    theory for supervisor harassment and may bring a direct negligence
    claim against the employer for coworker harassment. The fighting issue
    is whether the direct negligence theory also may be used for supervisor
    19
    harassment.    Because supervisors are employees and the caselaw has
    not limited recovery to vicarious liability, we conclude a plaintiff can elect
    to sue an employer for supervisor harassment under either theory.
    We begin with the text of the statute. Iowa Code section 216.6(1)
    (2011) forbids the creation of a hostile working environment, stating,
    It shall be an unfair or discriminatory practice for any:
    a. Person to refuse to hire, accept, register, classify, or
    refer for employment, to discharge any employee, or to
    otherwise discriminate in employment against any applicant
    for employment or any employee because of the . . . sex . . .
    of such applicant or employee, unless based upon the nature
    of the occupation.
    To establish a hostile-work-environment claim under the ICRA,
    the plaintiff must show: (1) he or she belongs to a protected
    group; (2) he or she was subjected to unwelcome
    harassment; (3) the harassment was based on a protected
    characteristic; and (4) the harassment affected a term,
    condition, or privilege of employment.
    Boyle, 710 N.W.2d at 746 (quoting Farmland Foods, 672 N.W.2d at 744).
    Harassment affects a term, condition, or privilege of employment “[w]hen
    the workplace is permeated with ‘discriminatory intimidation, ridicule,
    and insult’ . . . ‘sufficiently severe or pervasive to alter the conditions of
    the victim’s employment and create an abusive working environment.’ ”
    Farmland Foods, 672 N.W.2d at 743 (alterations in original) (quoting
    Harris v. Forklift Sys., Inc., 
    510 U.S. 17
    , 21, 
    114 S. Ct. 367
    , 370 (1993)).
    When harassment is perpetrated by a nonsupervisory employee, an
    employer will be liable if the plaintiff proves the employer “knew or
    should have known of the harassment and failed to take proper remedial
    action.” Id. at 744 (quoting Stuart v. Gen. Motors Corp., 
    217 F.3d 621
    ,
    631 (8th Cir. 2000)).    However, when harassment is perpetrated by a
    supervisory employee, an employer may be subject to vicarious liability.
    20
    Id.   The employer defending a vicarious liability claim may assert the
    Faragher–Ellerth affirmative defense
    by showing it: (1) “exercised reasonable care to prevent and
    correct promptly any . . . harassing behavior,” and (2) “that
    the plaintiff employee unreasonably failed to take advantage
    of preventive or corrective opportunities provided by the
    employer or to avoid harm otherwise.”
    Id. at 744 n.2 (quoting Faragher, 524 U.S. at 807, 118 S. Ct. at 2293).
    HES argues the jury should have been instructed on vicarious
    liability, including the Faragher–Ellerth defense, because vicarious
    liability replaced the negligence standard for supervisor harassment.
    Haskenhoff argues the vicarious liability standard did not replace, but
    rather supplemented, the direct negligence standard. Because the ICRA
    hostile-work-environment claim is modeled after its Title VII counterpart,
    we consider federal law instructive. 2           Boyle, 710 N.W.2d at 749–50
    (recognizing that Title VII hostile-work-environment claim has the same
    elements as ICRA claim); see also DeBoom, 772 N.W.2d at 7 (“When
    interpreting discrimination claims under Iowa Code chapter 216, we turn
    2It  has been suggested that we should not rely on federal law because Iowa civil
    rights statutes were enacted before Title VII. The Iowa legislature, however, did not
    expressly include a hostile-work-environment provision in the ICRA. See Iowa Code
    § 216.6(1). Rather, the claim has been developed through our caselaw, beginning in
    1990, based expressly on Title VII precedent. We first recognized a hostile-work-
    environment claim for sex discrimination in Lynch v. City of Des Moines, 
    454 N.W.2d 827
    , 833 (Iowa 1990), relying on Chauffeurs, Teamsters & Helpers, Local Union No. 238
    v. Iowa Civil Rights Commission, 
    394 N.W.2d 375
    , 378 (Iowa 1986). Chauffeurs, in turn,
    delineated the elements of a racial hostile-work-environment harassment claim, relying
    on Henson v. City of Dundee, 
    682 F.2d 897
    , 909 (11th Cir. 1982), a Federal Title VII
    case, for the appropriate framework under the ICRA. Chauffeurs, 394 N.W.2d at 378,
    381 (holding union liable when members harassed African-American man with racial
    epithets and threatening actions). In Meritor Savings Bank, FSB v. Vinson, the Supreme
    Court also relied on Henson to adopt the framework for a Title VII hostile-work-
    environment claim for sex discrimination. 
    477 U.S. 57
    , 66–67, S. Ct. 2399, 2405
    (1986). Henson states that to hold an employer responsible for “creating or condoning
    [a hostile] environment at the workplace,” the plaintiff must prove, among other things,
    “the employer knew or should have known of the harassment in question and failed to
    take prompt remedial action.” 682 F.2d at 901, 905.
    21
    to federal law, including Title VII of the United States Civil Rights Act
    . . . .”).   Accordingly, we will review the development of these liability
    theories under federal caselaw and the interplay of those decisions with
    our court’s precedents.
    The United States Supreme Court first recognized hostile-work-
    environment sexual harassment as actionable discrimination in Meritor
    Savings Bank, FSB v. Vinson, 
    477 U.S. 57
    , 66, 
    106 S. Ct. 2399
    , 2405
    (1986), notably a supervisor-harassment case.         Although the Court
    declined to adopt a definitive rule for sexual-harassment liability, it
    expressly rejected the notion that “employers are always automatically
    liable for sexual harassment by their supervisors.” Id. at 72, 106 S. Ct.
    at 2408. Instead, the Court looked to “agency principles for guidance” in
    setting liability standards. Id. at 72, 106 S. Ct. at 2408. A four-justice
    concurrence noted the predominant standard at the time for coworker-
    harassment liability: that an employer will be liable when it “knows or
    should have known of the conduct, unless it can show that it took
    immediate and appropriate corrective action.”      Id. at 74, 106 S. Ct. at
    2409 (Marshall, J., concurring) (quoting 29 C.F.R. § 1604.11(c), (d)
    (1985)).
    Four years later, in Lynch v. City of Des Moines, we held that
    “maintenance of a sexually hostile work environment through sexual
    harassment is a form of illegal sex discrimination under [the ICRA].” 
    454 N.W.2d 827
    , 833 (Iowa 1990). We determined the plaintiff was required
    to prove “the employer knew or should have known of the harassment
    and failed to take prompt and appropriate remedial action.”             Id.
    Although Lynch was a coworker-harassment case, subsequent decisions
    recognized this standard applied to both supervisor and coworker
    harassment under the ICRA.          See Greenland v. Fairtron Corp., 500
    
    22 N.W.2d 36
    , 38 (Iowa 1993) (citing same standard for supervisor
    harassment); Vaughn v. Ag Processing, Inc., 
    459 N.W.2d 627
    , 634 (Iowa
    1990) (en banc) (applying same standard to supervisor harassment);
    Edmunds v. Mercy Hosp., 
    503 N.W.2d 877
    , 879 (Iowa Ct. App. 1993)
    (noting same standard for supervisor harassment).
    In 1998, the United States Supreme Court recognized employer
    vicarious liability for supervisor harassment. Ellerth, 524 U.S. at 759,
    118 S. Ct. at 2267.     The Court relied on the Restatement (Second) of
    Agency, which states,
    (2) A master is not subject to liability for the torts of his
    servants acting outside the scope of their employment,
    unless:
    ....
    (b) the master was negligent or reckless, or
    ....
    (d) the servant purported to act or speak on behalf of
    the principal and there was reliance upon apparent
    authority, or he was aided in accomplishing the tort by the
    existence of the agency relation.
    Id. at 758, 118 S. Ct. at 2267 (quoting Restatement (Second) of Agency
    § 219(2) (1957)).   The Court reasoned harassment committed by a
    supervisor was “aided by the agency relation” within the scope of section
    (d) when a supervisor takes a tangible employment action against the
    employee because “the injury could not have been inflicted absent the
    agency relation. . . . A tangible employment decision requires an official
    act of the enterprise, a company act.” Id. at 761–62, 763, 118 S. Ct. at
    2269; see also Faragher, 524 U.S. at 802, 118 S. Ct. at 2290 (“[I]n
    implementing Title VII it makes sense to hold an employer vicariously
    liable for some tortious conduct of a supervisor made possible by abuse
    of his supervisory authority, and that the aided-by-agency-relation
    principle embodied in § 219(2)(d) of the Restatement provides an
    23
    appropriate starting point for determining liability . . . .”).   In addition,
    even when no tangible employment action results, the Court observed
    that “a supervisor’s power and authority invests his or her harassing
    conduct with a particular threatening character, and in this sense, a
    supervisor is always aided by the agency relation.” Ellerth, 524 U.S. at
    763, 118 S. Ct. at 2269. Thus, the Court held that the employer would
    be vicariously liable unless it could show
    (a) that [it] exercised reasonable care to prevent and correct
    promptly any sexually harassing behavior, and (b) that the
    plaintiff employee unreasonably failed to take advantage of
    any preventive or corrective opportunities provided by the
    employer or to avoid harm otherwise.
    Id. at 765, 118 S. Ct. at 2270. The Court echoed this vicarious liability
    standard for supervisor liability in Faragher, another supervisor-
    harassment case decided on the same day. 524 U.S. at 807, 118 S. Ct.
    at 2292–93.
    Iowa adopted the vicarious liability standard of Ellerth and
    Faragher in Farmland Foods, a hostile-work-environment claim under
    the ICRA.     672 N.W.2d at 744.          Since then, employees bringing
    harassment claims under the ICRA have used the vicarious liability
    standard to hold employers liable for supervisor harassment. See, e.g.,
    Reed v. Cedar County, 
    474 F. Supp. 2d 1045
    , 1061–62 (N.D. Iowa 2007);
    Krambeck v. Children & Families of Iowa, Inc., 
    451 F. Supp. 2d 1037
    ,
    1041 (S.D. Iowa 2006); Lopez v. Aramark Unif. & Career Apparel, Inc.,
    
    426 F. Supp. 2d 914
    , 949 (N.D. Iowa 2006); Fisher v. Elec. Data Sys., 
    278 F. Supp. 2d 980
    , 986–87 (S.D. Iowa 2003).
    Merely because vicarious liability is available in cases of supervisor
    harassment does not mean the negligence standard in place before
    Ellerth, Faragher, and Farmland Foods has been abrogated.              To the
    24
    contrary, Ellerth expressly states that the direct negligence standard, set
    forth in subsection (b) of the Restatement of Agency, remains an
    alternative ground for establishing employer liability for supervisor
    harassment:
    Subsections (b) and (d) are possible grounds for
    imposing employer liability on account of a supervisor’s acts
    and must be considered. Under subsection (b), an employer
    is liable when the tort is attributable to the employer’s own
    negligence.      Thus, although a supervisor’s sexual
    harassment is outside the scope of employment because the
    conduct was for personal motives, an employer can be liable,
    nonetheless, where its own negligence is a cause of the
    harassment. An employer is negligent with respect to sexual
    harassment if it knew or should have known about the
    conduct and failed to stop it. Negligence sets a minimum
    standard for employer liability under Title VII; but Ellerth
    seeks to invoke the more stringent standard of vicarious
    liability.
    Ellerth, 524 U.S. at 758–59, 118 S. Ct. at 2267 (emphasis added)
    (citation omitted).     We conclude the vicarious liability theory was
    intended to supplement, not replace, the direct negligence theory for
    supervisor harassment.
    The Supreme Court’s decision in Vance v. Ball State University, 
    570 U.S.
    ___, 
    133 S. Ct. 2434
     (2013), is not to the contrary.       At issue in
    Vance was whether a certain employee was merely a coworker, for which
    the employer could only be held liable under the negligence standard, or
    a supervisor, for which the employer could also face vicarious liability.
    See id. at ___, 133 S. Ct. at 2443.    The Court stated that “Ellerth and
    Faragher   identified    two   situations   in   which   the   aided-in-the-
    accomplishment rule warrants employer liability even in the absence of
    negligence.”   Id. at ___, 133 S. Ct. at 2441 (emphasis added).        That
    sentence simply confirms a nonnegligent employer can be vicariously
    liable for its supervisor’s harassment. See id. at ___, 133 S. Ct. at 2439
    25
    (“[A]n employer’s liability for such harassment may depend on the status
    of the harasser.” (Emphasis added.)). We read nothing in Vance that
    precludes allowing a direct negligence theory.     While Vance notes that
    “[i]n cases in which the harasser is a ‘supervisor’ . . . different rules
    apply,” that simply reiterates that vicarious liability is imposed only for
    supervisor harassment, not for harassment by a nonsupervisory
    coemployee. Id. at ___, 133 S. Ct. at 2439.
    Several federal circuit courts of appeals after Ellerth and Faragher
    have held that suits for supervisor harassment can be brought under
    either vicarious liability or direct negligence theories. In Sharp v. City of
    Houston, the United States Court of Appeals for the Fifth Circuit
    recognized that a claim for supervisor harassment could proceed on a
    negligence “knew or should have known” theory because the negligence
    standard for supervisor harassment was “not disturbed by Faragher or
    [Ellerth].”   
    164 F.3d 923
    , 929 (5th Cir. 1999).     The court noted that
    although the negligence standard was typically applied to coworker
    harassment, “[t]he concept of negligence thus imposes a ‘minimum
    standard’ for employer liability—direct liability—under title VII, a
    standard that is supplemented by the agency-based standards for
    vicarious liability as articulated in Faragher and [Ellerth].” Id. (citation
    omitted); see also Debord v. Mercy Health Sys. of Kan., Inc., 
    737 F.3d 642
    , 650–53 (10th Cir. 2013) (analyzing employer liability for supervisor
    harassment under both negligence and vicarious liability standards);
    Dees v. Johnson Controls World Servs., Inc., 
    168 F.3d 417
    , 421 (11th Cir.
    1999) (“[A]n employer can be held directly liable for a supervisor’s
    harassment when the employer either intended, or negligently permitted,
    the tortious conduct to occur.”); Wilson v. Tulsa Junior Coll., 
    164 F.3d 534
    , 540 n.4 (10th Cir. 1998) (recognizing the “continuing validity of
    26
    negligence as a separate basis for employer liability” in action in which
    employee alleged supervisor harassment).       HES cites no decision that
    holds a plaintiff cannot bring a direct negligence claim against an
    employer for supervisor harassment, and we have found none.
    That employers are directly liable for their own negligence is not a
    new proposition. The Restatement (Second) of Employment Law, section
    4.02, at 134 (2015), entitled “Employer’s Direct Liability to Employees for
    Its Own Conduct,” provides that “an employer is subject to liability in
    tort to an employee for harm caused in the course of employment by the
    tortious conduct of the employer or the controlling owner.”      (Emphasis
    added.)   Similarly, the Restatement (Third) of Agency, section 7.03, at
    151 (2006), provides that a principal is liable for its own negligence in
    “selecting, supervising, or otherwise controlling the agent” in addition to
    any vicarious liability that may be imposed via the agent’s actions.
    We hold that plaintiffs under the ICRA may proceed against the
    employer on either a direct negligence or vicarious liability theory for
    supervisor harassment in a hostile-work-environment case.                The
    Faragher–Ellerth affirmative defense, with the burden of proof on the
    employer, applies only to claims of vicarious liability. Ellerth, 524 U.S. at
    764, 118 S. Ct. at 2270 (adopting affirmative defense “in order to
    accommodate the agency principle of vicarious liability for harm caused
    by misuse of supervisory authority” (emphasis added)); accord Faragher,
    524 U.S. at 807, 118 S. Ct. at 2292; see also Johnson v. Shinseki, 
    811 F. Supp. 2d 336
    , 348 n.2 (D.D.C. 2011) (holding because the court
    applied the negligence standard, “the Faragher defense is inapplicable”);

    , 1081 (D. Kan. 1999) (rejecting Faragher–Ellerth

    defense in direct negligence action). By contrast, on a direct negligence
    claim, the plaintiff must prove “the employer . . . failed to take prompt
    and appropriate remedial action.” Lynch, 454 N.W.2d at 833.
    B. Whether the District Court Correctly Instructed the Jury
    on the Direct Negligence Theory. We next address whether the jury
    was correctly instructed on the direct negligence theory.     The district
    court essentially adopted Haskenhoff’s proposed marshaling instruction,
    which omitted an element she was required to prove—that HES “failed to
    take prompt and appropriate remedial action.” Id. HES objected to the
    omission of that element, and we conclude the district court prejudicially
    erred by overruling the objection and giving Instruction No. 14 without
    that language.   Whether HES in fact took “prompt and appropriate
    action” was a fighting issue at trial and a jury question. Haskenhoff did
    not establish as a matter of law that HES failed to take prompt and
    appropriate action.
    The standard requiring a plaintiff to prove the employer’s failure to
    take prompt remedial action “places a reasonable duty on an employer
    who is aware of discrimination in the workplace to take reasonable steps
    to remedy it.” Vaughn, 459 N.W.2d at 634. Whether the employer met
    this duty is a question of fact and turns on “the gravity of the harm, the
    nature of the work environment, and the resources available to the
    employer.” Id.
    The first time Haskenhoff complained to management about
    Howes’s harassment, senior management promptly met with her and
    Howes. Howes was verbally confronted in a manner that led him and
    others to believe he faced termination. Howes apologized to Haskenhoff,
    and Haskenhoff, believing the harassment issue was resolved, asked that
    no further action be taken at that time.     See Nurse “BE” v. Columbia
    28
    Palms W. Hosp. Ltd. P’ship, 
    490 F.3d 1302
    , 1310 (11th Cir. 2007)
    (holding that if employee “did not want [the harassing behavior] reported
    or acted upon, then [the employer] would not have been placed on proper
    notice of the harassment” (alterations in original) (quoting Olson v.
    Lowe’s Home Ctrs., Inc., 130 F. App’x 380, 391 n.21 (11th Cir. 2005))).
    Haskenhoff made no further complaints to management during the next
    nine months.     HES management could reasonably assume its prior
    remedial efforts were adequate. See An v. Regents of Univ. of Cal., 94
    F. App’x 667, 676 (10th Cir. 2004) (determining employer not liable when
    initial complaint limited to one comment that made employee feel
    uncomfortable, then employee made no further complaint and assured
    management that things were “okay” until second complaint).
    When Haskenhoff next complained of harassment in August of
    2011, HES took immediate remedial action. A formal investigation was
    launched with outside counsel.        Witnesses were interviewed.     HES
    management      admonished      coemployees     to   conduct   themselves
    professionally and take down the offensive screen saver.            Sexual
    harassment training was scheduled.          Howes was disciplined and
    apologized. See Wilson, 164 F.3d at 540 (jury may consider availability
    and effectiveness of employer’s complaint procedure). HES was entitled
    to have the jury decide whether Haskenhoff proved that it had failed to
    take prompt and appropriate action.
    Haskenhoff argues Vance imposes liability when an employer is
    negligent in allowing harassment to occur, regardless of notice or
    subsequent corrective action.    We disagree.   Haskenhoff relies on this
    sentence in Vance: “As an initial matter, an employer will always be liable
    when its negligence leads to the creation or continuation of a hostile
    29
    work environment.” 
    570 U.S.
    at ___, 133 S. Ct. at 2452. 3 However, the
    Vance Court, two paragraphs later, reiterates the relevance of the
    3It has been suggested that Vance created two types of negligence liability,
    negligence in failing to prevent the harassment and negligence in failing to remedy it.
    But the standard for both negligent failure to prevent and negligent failure to remedy is
    the same: an employer is only liable if he knows or should have known of the
    harassment and failed to take prompt measures to rectify it. See, e.g., Ocheltree v.
    Scollon Prods., Inc., 
    335 F.3d 325
    , 333–34 (4th Cir. 2003) (“[T]he employer may be liable
    in negligence if it knew or should have known about the harassment and failed to take
    effective action to stop it.” (Emphasis added.)); Sharp v. City of Houston, 
    164 F.3d 923
    ,
    929 (5th Cir. 1999) (“An employer may be liable for sexual harassment if it ‘knew or
    should have known of the harassment in question and failed to take prompt remedial
    action.’ ” (quoting Williamson v. City of Houston,

    negligent either in discovering or remedying the harassment.’ An employer’s legal duty

    , 677 (10th Cir. 1990) (stating it was an “essential element for employer
    liability” that the plaintiff establish the employer “inadequately responded to incidents
    of harassment of which it knew or should have known”); Paroline v. Unisys Corp., 
    879 F.2d 100
    , 106 (4th Cir. 1989) (“In a hostile environment claim such as we have here, an
    employer is liable for one employee’s sexual harassment of another worker if the
    employer had ‘actual or constructive knowledge of the existence of a sexually hostile
    working environment and took no prompt and adequate remedial action.’ ” (quoting
    Swentek v. USAIR, Inc., 
    830 F.2d 552
    , 558 (4th Cir. 1987) (emphasis added))), vacated
    in part on other grounds, 
    900 F.2d 27
     (4th Cir. 1990).
    The employer’s knowledge and response are key: if the employer did not have
    notice of the harassment, either actual or constructive, the employer is not liable. If an
    employer is negligent in failing to discover workplace harassment, the employee
    proceeds under a should-have-known framework, but the employer’s responsive actions
    are still relevant. See, e.g., Sharp, 164 F.3d at 930 (analyzing employer’s constructive
    knowledge of conduct and concluding it could be liable because it should have known of
    harassment and tolerated it); Adler, 144 F.3d at 673, 676–77; Paroline, 879 F.2d at 107
    (stating that employee must prove the employer should have reasonably anticipated
    harassment because of its pervasiveness and that the employer “failed to take action
    reasonably calculated to prevent such harassment”). Here, however, it is undisputed
    that HES had actual knowledge of the harassment—Haskenhoff complained twice.
    Thus, the jury should have been instructed that HES was liable only if it failed to take
    prompt responsive action.
    30
    employer’s remedial efforts under a negligence theory: “Evidence that an
    employer did not monitor the workplace, failed to respond to complaints,
    failed to provide a system for registering complaints, or effectively
    discouraged complaints from being filed would be relevant.” Id. at ___,
    133 S. Ct. at 2453. Removing the requirement for the plaintiff to prove
    the employer neglected to take corrective action would impose strict or
    automatic liability on an employer whenever supervisor harassment
    occurred without a tangible adverse employment action, a position our
    court has never adopted and the Supreme Court has expressly declined
    to adopt.     See Faragher, 524 U.S. at 804–05, 118 S. Ct. at 2291–92.
    Haskenhoff cites cases that she contends establish that an employer can
    be liable regardless of whether it took remedial action. Yet each of those
    decisions indicates the employer’s remedial action or lack thereof is
    relevant to whether it acted negligently. 4
    It has been suggested that the jury need not be instructed
    regarding the employer’s remedial efforts if management, negligently
    unaware of harassment, took no action.                     That is not this case.

    Haskenhoff on two occasions complained to management about Howes’s
    harassment.       On both occasions, management took action to stop the
    harassment. It was for the jury to determine, under proper instructions,
    whether HES’s responses were adequate—that is, whether it “failed to
    take prompt and appropriate remedial action.”                   Lynch, 454 N.W.2d at
    833.
    We decline to interpret the ICRA to impose employer liability for
    supervisor harassment under a direct negligence theory despite the
    employer’s prompt and appropriate action to end the harassment.
    Notably, the Equal Employment Opportunity Commission (EEOC) in
    interpreting Title VII does not go so far.               See 29 C.F.R. § 1604.11(d)
    (2016) (“[A]n employer is responsible for acts of sexual harassment in the
    workplace where the employer (or its agents or supervisory employees)
    knows or should have known of the conduct, unless it can show that it
    took immediate and appropriate corrective action.”                 (Emphasis added.)).
    Indeed, most federal circuit model jury marshaling instructions for
    sexual harassment under Title VII require the plaintiff to prove the
    defendant failed to take prompt and appropriate remedial action. 5 None
    5See Pattern Jury Instruction for Cases of Emp’t Discrimination for the Dist. Cts.
    of the U.S. Ct. of Appeals for the First Circuit 2.3 (2011) (requiring plaintiff to prove six
    elements, including “Fifth, [defendant; management level employees of defendant] either
    knew or should have known of the harassment; and Sixth, [defendant; management
    level employees of defendant] failed to take prompt and appropriate remedial action”
    (emphasis added) (footnote omitted)); Third Circuit Model Civil Jury Instruction 5.1.5
    (2016) (“You must find for [defendant] if you find that [defendant] has proved both of the
    following elements by a preponderance of the evidence: First, [Defendant] exercised
    reasonable care to prevent harassment in the workplace on the basis of [protected
    status], and also exercised reasonable care to promptly correct any harassing behavior
    that does occur.” (Emphasis added.)); Fifth Circuit Pattern Civil Jury Instruction 11.4
    (2014) (“Plaintiff [name] must prove that: a. the harassment was known by or
    communicated to a person who had the authority to receive, address, or report the
    complaint, . . . or the harassment was so open and obvious that Defendant [name]
    should have known of it; and b. Defendant [name] failed to take prompt remedial action
    designed to stop the harassment.” (Emphasis added.)); Fed. Civil Jury Instruction of the
    32
    of the federal circuits hold an employer liable merely for “negligently
    creating or continuing a hostile work environment”—as the jury was
    instructed in this case. Rather, a party must not only show the employer
    knew of the harassment, but also that it unreasonably failed to take
    remedial action. See, e.g., Swinton, 270 F.3d at 803 (“[I]t was Swinton’s
    burden . . . to prove that management knew or should have known of the
    harassment and ‘failed to take reasonably prompt, corrective action.’ ”).
    Under the instruction as given, the jury could have found HES liable
    even if the jury found the employer had in fact taken prompt and
    appropriate remedial action.
    Employers would lose a key incentive to take corrective action if
    they were automatically liable for harassment whether or not they put a
    stop to it. As the Fifth Circuit observed, “Imposing vicarious liability on
    an employer for a supervisor’s ‘hostile environment’ actions despite its
    swift and appropriate remedial response to the victim’s complaint would
    . . . undermine not only Meritor but Title VII’s deterrent policy.” Indest v.
    Freeman Decorating, Inc., 
    164 F.3d 258
    , 266 (5th Cir. 1999). Employers
    are better deterred from allowing harassment to continue if their prompt
    corrective action will avoid liability.         See Ellerth, 524 U.S. at 745, 118
    S. Ct. at 2261 (“Limiting employer liability is also consistent with Title
    _________________________
    Seventh Circuit 3.04 (2015) (stating plaintiff must prove “seven things by a
    preponderance of the evidence: . . . 7. Defendant did not take reasonable steps to [correct
    the situation]/[prevent harassment from recurring”] (emphasis added)); Model Civil Jury
    Instruction for the Dist. Cts. of the Eighth Circuit 8.42 (2017) (requiring plaintiff to
    show seven elements, including “Seventh, the defendant failed to take prompt and
    appropriate corrective action to end the harassment”); Model Civil Jury Instructions for
    the Dist. Cts. of the Ninth Circuit 10.7 (2017) (“The plaintiff has the burden of proving
    both of the following elements by a preponderance of the evidence: . . . 2. the
    defendant or a member of the defendant’s management knew or should have known of
    the harassment and failed to take prompt, effective remedial action reasonably calculated
    to end the harassment.” (Emphasis added.)).
    33
    VII’s purpose to the extent it would encourage the creation and use of
    antiharassment policies and grievance procedures.”).
    Finally, allowing one marshaling instruction on direct negligence—
    requiring the plaintiff to prove the employer knew or should have known
    of the harassment and failed to take prompt and appropriate remedial
    action—for   both   coemployee     and   supervisor    harassment    avoids
    confusing jury instructions with differing standards.       It also avoids
    issues over whether a particular employee is a supervisor.           Mixing
    different authority levels of employees “presents no problem for the
    negligence standard.” Vance, 
    570 U.S.
    at ___, 133 S. Ct. at 2452.
    Haskenhoff is the master of her own pleadings. But by deciding to
    pursue a direct negligence theory for supervisor harassment, rather than
    vicarious liability, she assumed the burden of proving not only that HES
    knew or should have known of Howes’s harassment, but also that it
    failed to take prompt remedial action to stop it. Lynch, 454 N.W.2d at
    833–34.
    While the reasonableness of an employer’s response to
    sexual harassment is at issue under both standards, the
    plaintiff must clear a higher hurdle under the negligence
    standard, where she bears the burden of establishing her
    employer’s negligence, than under the vicarious liability
    standard, where the burden shifts to the employer to prove
    its own reasonableness and the plaintiff’s negligence.
    Curry v. District of Columbia, 
    195 F.3d 654
    , 660 (D.C. Cir. 1999); see also
    Swinton, 270 F.3d at 804 (“It might reasonably be argued, in fact, that
    employers are ‘better off’ in the negligence context, where the plaintiff is
    required to prove both the employer’s knowledge of the harassment (or
    that it should have known) and that it failed to take reasonable corrective
    action.”). The district court erred by omitting that element of proof from
    Instruction No. 14. This error was not harmless.
    34
    Reversal is required when jury instructions contain a “material
    misstatement of the law” or are misleading or confusing.       Rivera, 865
    N.W.2d at 902. When an instruction fails to convey a central principle of
    liability, this warrants a new trial. See Benn v. Thomas, 
    512 N.W.2d 537
    ,
    539–40 (Iowa 1994) (remanding for new trial when jury instruction on
    proximate cause “failed to adequately convey the existing law”); Law v.
    Hemmingsen, 
    249 Iowa 820
    , 825–26, 
    89 N.W.2d 386
    , 390–91 (1958)
    (determining refusal to instruct on well-settled principle of negligence “at
    the very heart of the case” was error). The instruction omitted a central
    element of the plaintiff’s claim—to show the failure of the employer to
    take prompt and appropriate remedial action. Omission of this element
    was a material misstatement of the law and entitles HES to a new trial.
    See State v. Pearson, 
    804 N.W.2d 260
    , 265 n.1 (Iowa 2011) (holding
    omission in the jury instruction of element of offense “requires a new
    trial”); Law, 249 Iowa at 825–26, 89 N.W.2d at 390–91 (reversing
    because it was error for court to refuse to instruct on combined
    negligence).
    “We assume prejudice unless the record affirmatively establishes
    that there was no prejudice.” Rivera, 865 N.W.2d at 903. No prejudice
    results when “one instruction arguably omits a legal requirement that is
    included in subsequent instructions on the ground that the instructions
    are to be read as a whole.”        Id.   “When, however, an inadequate
    instruction relating to the right of recovery goes to ‘the very heart of the
    case,’ it is not rescued by abstract instructions elsewhere.” Id. (quoting
    Law, 249 Iowa at 825, 89 N.W.2d at 390). That is what we have here.
    The district court gave a separate instruction, No. 24, on remedial
    action, which stated,
    35
    Once an employer knows or should have known of
    sexual harassment, it must take prompt remedial action
    reasonably calculated to end the conduct. The employer has
    the duty to take this remedial action even if an employee
    asks the employer not to do anything.
    (Emphasis omitted.)         This instruction was not cross-referenced in the
    marshaling instruction or any other instruction and does not cure the
    flaw in the marshaling instruction when the instructions are read as a
    whole. The jury was nowhere told Haskenhoff had the burden to prove
    HES failed to take prompt and appropriate remedial action to end the
    harassment. 6
    Haskenhoff cites no case holding the fatal omission in the
    marshaling instruction could be cured by counsel during summation.7
    6Nor  is the plaintiff’s burden of proof addressed in Instruction No. 22, entitled
    “Existence of Official Policies—Explained,” which told the jury that they could “consider
    whether the defendant exercised reasonable care to”
    [a] Monitor the workplace;
    [b] Provide a system for making complaints;
    [c] Encourage employees who believe they are being harassed to
    complain
    [d] Conduct prompt, thorough and impartial investigations into any
    potential sexual harassment they become aware of, whether it is through a
    complaint or observation or hearsay;
    [e] Reasonably assure that any person who reports sexual harassment
    will not suffer retaliation;
    [f] Communicate their harassment policy to employees so employees will
    understand what they may and may not do in the workplace;
    [g] Educate the workforce, especially members of management, with
    appropriate training to avoid committing sexual harassment . . . .
    (Emphasis added.) This instruction allowed the jury to find for Haskenhoff if HES was
    negligent in any of the above respects, even if the jury found the employer in fact took
    prompt and appropriate remedial action to end the harassment.
    7Hillrichs v. Avco Corp. is not to the contrary. 
    478 N.W.2d 70
     (Iowa 1991),
    overruled on other grounds by Reed v. Chrysler Corp., 
    494 N.W.2d 224
    , 230 (Iowa 1992),
    overruled by Jahn v. Hyundai Motor Corp., 
    773 N.W.2d 550
    , 558–60 (Iowa 2009)).
    There, we determined a uniform jury instruction on ordinary care adequately conveyed
    the proper legal concept to the jury because it referred to care that “a reasonably careful
    person would use under similar circumstances.” Id. at 74. We noted that the words
    “under similar circumstances” allowed the standard to “adjust[] to both the status of
    36
    To the contrary, Haskenhoff’s counsel took advantage of the flawed jury
    instruction in her closing argument. She did not say it was plaintiff’s
    burden to prove HES failed to take prompt remedial action, but instead
    argued
    Number 24 talks about remedial action. Once an employer
    knows or should know about the sexual harassment, it must
    take prompt remedial action reasonably calculated to end
    the conduct. The employer has a duty to take this remedial
    action even if an employee asks the employer to do nothing.
    (Emphasis added.) This is not a case like State v. Thorndike in which
    counsel’s closing argument effectively cured the instructional error by
    conceding the improper instruction did not apply under the evidence.
    
    860 N.W.2d 316
    , 322–23 (Iowa 2015).
    There was no instruction given by the court that allowed HES to
    argue plaintiff could not recover without proving it failed to take prompt
    remedial action.      Closing arguments were lengthy, extending from the
    morning until 2:30 p.m. and encompassing 130 pages of the trial
    transcript. Closing arguments “generally carry less weight with a jury
    than do instructions from the court.” Boyde v. California, 
    494 U.S. 370
    ,
    384, 
    110 S. Ct. 1190
    , 1200 (1990).             “The former are usually billed in
    advance to the jury as matters of argument, not evidence, and are likely
    viewed as the statements of advocates; the latter . . . are viewed as

    We therefore determine HES is entitled to a new trial. 8 Rivera, 865
    N.W.2d at 892 (“Prejudice occurs and reversal is required if jury
    instructions have misled the jury, or if the district court materially
    misstates the law.”).
    C. Whether the District Court Erred in Instructing on a
    “Motivating Factor” Standard for Retaliatory Discharge. HES argues
    the district court erroneously adopted the lower “motivating factor”
    causation standard used in discriminatory discharge claims (Iowa Code
    section 216.6(1)(a)), rather than the higher “significant factor” causation
    standard used in retaliatory discharge claims (Iowa Code section
    8Because  it may arise on remand, we clarify Haskenhoff cannot prove that HES
    “knew or should have known” and failed to take remedial action by showing only that
    Howes “knew what he was doing” when he behaved inappropriately toward Haskenhoff.
    For example, the following exchange took place between Wendland and Haskenhoff’s
    counsel regarding the alleged harassment:
    Q. So regardless of whether somebody complains, if men are
    commenting on another female’s breasts in the workplace, that would be
    a violation of Homeland’s policy? A. Absolutely. If it was brought to my
    attention and I knew about it or anybody in the company knew about it,
    we would address it immediately.
    Q. Including the plant manager?            A. Including the plant
    manager.
    Q. And obviously if your plant manager is making the comments
    about a woman’s breast, he knows he’s doing that; yes?
    It is not sufficient that the perpetrator himself knows what he is doing, even if he is a
    supervisor. Rather, to be placed on actual notice, someone “with authority to address
    the problem” must be notified. Sharp, 164 F.3d at 930 (quoting Nash v. Electrospace
    Sys., Inc., 
    9 F.3d 401
    , 404 (5th Cir. 1993); see also Sandoval v. Am. Bldg. Maint. Indus.,
    Inc., 
    578 F.3d 787
    , 801 (8th Cir. 2009) (“An employer has actual notice of harassment
    when sufficient information either comes to the attention of someone who has the power
    to terminate the harassment, or it comes to someone who can reasonably be expected to
    report or refer a complaint to someone who can put an end to it.”). The inquiry must
    focus on whether someone with authority to discipline Howes and to take remedial
    action knew of and failed to address the conduct. Sharp, 164 F.3d at 930 (“In the
    context of sexual harassment, such persons are those with remedial power over the
    harasser.”). Alternatively, Haskenhoff may prove constructive knowledge by showing
    harassment was so open and pervasive that, in the exercise of reasonable care, it
    should have been discovered by management-level employees.               See Alvarez v.
    Des Moines Bolt Supply, Inc., 
    626 F.3d 410
    , 422 (8th Cir. 2010).

    216.11(2)).   Haskenhoff argues that (1) under DeBoom, 772 N.W.2d at
    12–13, the correct causation standard for all ICRA claims is the
    motivating-factor test, and (2) unlike federal law, a lower causation
    standard for retaliation should be used because the ICRA is a unified
    statute and should be read broadly to effectuate its broad remedial goals.
    See Iowa Code § 216.18(1). We note DeBoom was not a retaliation case
    and apply our retaliation decisions that require the higher causation
    standard. 772 N.W.2d at 13.
    Our analysis begins with the text of the statute. The ICRA, Iowa
    Code section 216.11(2), makes it an unfair or discriminatory practice for
    [a]ny person to . . . retaliate against another person in any of
    the rights protected against discrimination by this chapter
    because such person has lawfully opposed any practice
    forbidden under this chapter, obeys the provisions of this
    chapter, or has filed a complaint, testified, or assisted in any
    proceeding under this chapter.
    In order to recover for retaliatory discharge, the plaintiff must prove
    (1) he or she was engaged in statutorily protected activity,
    (2) the employer took adverse employment action against
    him or her, and (3) there was a causal connection between
    his or her participation in the protected activity and the
    adverse employment action taken.
    Boyle, 710 N.W.2d at 750.         The causation standard in retaliatory
    discharge cases has been characterized as “a high one.”              City of
    Hampton, 554 N.W.2d at 535 (quoting Hulme, 480 N.W.2d at 42). The
    causal connection “must be a ‘significant factor’ motivating the adverse
    employment decision.” Id. (quoting Hulme, 480 N.W.2d at 42). A factor
    is significant if the reason “ ‘tips the scales decisively one way or the
    other,’ even if it is not the predominate reason behind the employer’s
    decision.” Teachout v. Forest City Cmty. Sch. Dist., 
    584 N.W.2d 296
    , 302
    39
    (Iowa 1998) (quoting Smith v. Smithway Motor Xpress, Inc., 
    464 N.W.2d 682
    , 686 (Iowa 1990)).
    A separate provision, Iowa Code section 216.6(1)(a), forbids
    discriminatory discharge, i.e., discharge because of discrimination based
    on a protected characteristic.           Retaliatory discharge is different; it
    prohibits discharge or discrimination based on the employee’s engaging
    in a protected activity. See id. § 216.11(2). Though the two concepts are
    related, they are not the same; one prohibits status-based discriminatory
    discharge, while the other prohibits discharge based on a protected
    activity in which an employee chooses to engage. See Univ. of Tex. Sw.
    Med. Ctr. v. Nassar, 
    570 U.S.
    ___, ___, 
    133 S. Ct. 2517
    , 2532 (2013)
    (explaining the difference between status-based claims and retaliation
    claims). Under the discriminatory discharge statute, an employee must
    show discrimination based on a characteristic—not engaging in a
    protected activity—constituted a “motivating factor” in the adverse action
    of the employer.      DeBoom, 772 N.W.2d at 12–13.               Discrimination is a
    “motivating factor” in an adverse action if an employee’s status as a
    member of a protected class “played a part” in the employer’s decision.
    Id. at 12 (emphasis omitted). This is a lower causation standard than the
    significant-factor standard applied in retaliatory discharge cases under
    the ICRA and the common law. 9
    DeBoom clarified that the motivating-factor test applied to
    discriminatory discharge cases. See DeBoom, 772 N.W.2d at 13. But it
    did not alter—or even reference by name or Code section—retaliatory
    9This  standard does not require retaliation to be the sole cause; the retaliatory
    motive may combine with other factors to produce the result so long as “the other
    factors alone would not have done so—if, so to speak, it was the straw that broke the
    camel’s back.” Burrage v. United States, 
    571 U.S.
    ___, 
    134 S. Ct. 881
    , 888 (2014).

    discharge claims. Id. Rather, in DeBoom, we were careful to note the
    difference between the discriminatory discharge causation standard and
    the “higher” causation standard of claims such as tortious discharge. Id.
    We have frequently compared tortious discharge under common law and
    retaliatory discharge under the ICRA, as the two have traditionally
    possessed similar elements and causation standards. See Teachout, 584
    N.W.2d at 301–02 (stating high causation standard for tortious discharge
    and comparing to Hulme, a retaliatory discharge case under the ICRA);
    see also Brown v. Farmland Foods, Inc., 
    178 F. Supp. 2d 961
    , 979 (N.D.
    Iowa 2001) (“[T]he Iowa Supreme Court has consistently sought guidance
    in its common-law retaliatory discharge cases from its decisions involving
    claims of statutory retaliation, which further demonstrates that the Iowa
    Supreme Court would analyze these distinct causes of action in a similar
    manner.”); cf. Scott Rosenberg & Jeffrey Lipman, Developing a Consistent
    Standard for Evaluating a Retaliation Case Under Federal and State Civil
    Rights Statutes and State Common Law Claims: An Iowa Model for the
    Nation, 53 Drake L. Rev. 359, 414–15 (2005) (“The federal courts have
    used the same approach in defining actionable employment conduct in
    both statutory and common law cases.”). We noted in DeBoom that the
    lower motivating-factor standard did not apply to tortious discharge, nor
    was it intended to alter the higher significant-factor causation standard
    used in ICRA retaliatory discharge claims. 772 N.W.2d at 13.
    Because Count II alleged retaliatory discharge under Iowa Code
    section   216.11   and   not   discriminatory   discharge   under   section
    216.6(1)(a), the jury should have been instructed on the correct
    causation   standard—requiring Haskenhoff to        prove   her   protected
    conduct was a significant factor. See, e.g., French v. Cummins Filtration,
    Inc., No. C11-3024-MWB, 
    2012 WL 3498566
    , at *3 (N.D. Iowa Aug. 15,
    41
    2012) (“[Under ICRA] [a]s to the causal connection element, the standard
    is high: ‘[T]he “causal connection” must be a “significant factor”
    motivating the adverse employment decision.’ ” (alteration in original)
    (quoting City of Hampton, 554 N.W.2d at 535)); Gilster v. Primebank, 
    884 F. Supp. 2d 811
    , 831 n.4 (N.D. Iowa 2012) (analyzing both Title VII and
    ICRA together using determinative-factor approach), overruled on other
    grounds,

     (8th Cir. 2014); Van Horn v. Best Buy Stores,
    L.P., 
    526 F.3d 1144
    , 1148 (8th Cir. 2008) (applying same higher
    causation to ICRA and federal claim).
    Haskenhoff       notes    the    ICRA       discriminatory     discharge      and
    retaliatory discharge provisions use “similar” language.                Compare Iowa
    Code § 216.6(1)(a) (stating it is a “discriminatory practice for any . . .
    [p]erson to . . . discharge any employee . . . because of” a protected
    characteristic (emphasis added)), with id. § 216.11 (stating it is a
    “discriminatory practice for . . . [a]ny person to discriminate or retaliate
    against    another     person     in   any    of   the   rights    protected     against
    discrimination by this chapter because such person has lawfully opposed
    any practice forbidden under this chapter” (emphasis added)). 10 But, as
    we previously noted in Estate of Harris v. Papa John’s Pizza, the
    10The    phrase “because of” does not require a motivating-factor standard of
    causation. As the Supreme Court noted in Nassar, the default rule in interpreting
    causation in tort is that “[i]n the usual course, this standard requires plaintiff to show
    ‘that the harm would not have occurred’ in the absence of—that is, but for—the
    defendant’s conduct.” 
    570 U.S.
    ___, 133 S. Ct. at 2525 (quoting Restatement of Torts
    § 431 cmt. a (1934) (negligence)). Additionally, “the ordinary meaning of ‘because of’ is
    ‘by reason of’ or ‘on account of.’ ” Id. at ___, 133 S. Ct. at 2527 (quoting Gross v. FBL
    Fin. Servs., Inc., 
    557 U.S. 167
    , 176, 
    129 S. Ct. 2343
    , 2350 (2009)). Thus, the Nassar
    Court concluded that when interpreting “because of,” it must mean that the retaliatory
    intent was “ ‘the “reason” that the employer decided to act,’ or, in other words, that
    ‘[retaliation] was the “but-for” cause of the employer’s adverse decision.’ ” Id. at ___,
    133 S. Ct. at 2527 (quoting Gross, 557 U.S. at 176, 129 S. Ct. at 2350).
    42
    retaliation provision of the ICRA mirrors almost exactly the retaliation
    provision of Title VII, which states,
    It shall be an unlawful employment practice for an employer
    to discriminate against any of his employees . . . because he
    has opposed any practice made an unlawful employment
    practice by this subchapter, or because he has made a
    charge, testified, assisted, or participated in any manner in
    an investigation, proceeding, or hearing under this
    subchapter.
    
    679 N.W.2d 673
    , 677 (Iowa 2004) (quoting 42 U.S.C.A. § 2000e–3
    (2004)). “Title VII was designed to ensure equal opportunity in
    employment for all, regardless of sex. The ICRA was modeled after Title
    VII, and therefore we have consistently employed federal analysis when
    interpreting the ICRA.”    Id. at 677–78 (citation omitted).     Finally, the
    ICRA’s elements for establishing a prima facie case of retaliation were
    derived “from federal decisions involving comparable provisions of Title
    VII of the Civil Rights Act of 1964.” Hulme, 480 N.W.2d at 42 (citing 42
    U.S.C. §§ 2000e–2000e-3).
    Title VII provides a higher causation standard for retaliation claims
    than discriminatory discharge actions. See Nassar, 
    570 U.S.
    at ___, 133
    S. Ct. at 2534. In Nassar, a retaliation case brought under Title VII, the
    Supreme Court explained that in codifying the 1991 Amendment to the
    Civil Rights Act, Congress did not intend to lower the causation standard
    for retaliatory discharge cases, although it unquestionably did so for
    discriminatory discharge. Id. at ___, 133 S. Ct. at 2528–30. The Court
    reasoned that the two provisions used different language and were found
    in different sections of the Act and that Congress had inserted the
    amendment into only one part.           Id.   The Court also pointed out the
    increasing number of retaliation claims being filed. Id. at ___, 
    133 S. Ct. 43
    at 2531. Lowering the causation standard, the Court explained, could
    increase the number of unfounded claims:
    In addition lessening the causation standard could
    also contribute to the filing of frivolous claims, which would
    siphon resources from efforts by employer[s], administrative
    agencies, and courts to combat workplace harassment.
    Consider in this regard the case of an employee who knows
    that he or she is about to be fired for poor performance,
    given a lower pay grade, or even just transferred to a
    different assignment or location. To forestall that lawful
    action, he or she might be tempted to make an unfounded
    charge of racial, sexual, or religious discrimination; then,
    when the unrelated employment action comes, the employee
    could allege that it is retaliation. . . . Even if the employer
    could escape judgment after trial, the lessened causation
    standard would make it far more difficult to dismiss dubious
    claims at the summary judgment stage.              It would be
    inconsistent with the structure and operation of Title VII to
    so raise the costs, both financial and reputational, on an
    employer whose actions were not in fact the result of any
    discriminatory or retaliatory intent. Yet there would be a
    significant risk of that consequence if respondent’s position
    were adopted here.
    Id. at ___, 133 S. Ct. at 2531–32 (citations omitted).
    Turning to the ICRA, the retaliatory discharge and discriminatory
    discharge provisions are codified at different sections of the Act, as they
    are in Title VII, which supports the same conclusion reached in Nassar
    that different causation standards apply.      See id. at ___, 133 S. Ct. at
    2530–31. Compare Iowa Code § 216.6 (discriminatory discharge), with id.
    § 216.11 (retaliatory discharge).       Moreover, as the Nassar Court
    concluded under Title VII, we have emphasized that the ICRA’s
    retaliation protections cannot be so low as to “immunize the complainant
    from   discharge   for   past   or   present   inadequacies,   unsatisfactory
    performance, or insubordination.” City of Hampton, 554 N.W.2d at 535–
    36 (quoting Hulme, 480 N.W.2d at 43).
    We reject Haskenhoff’s contention that we are “blindly” following
    federal law. First, we are following our own precedent: our cases have
    44
    made clear that the correct causation standard for a retaliatory discharge
    claim brought under section 216.11(2) of the ICRA is the significant-
    factor standard.   See id. at 535; Hulme, 480 N.W.2d at 42.          We are
    adhering to our consistent prior interpretations of the Act since 1992—
    interpretations that have not been disturbed by the legislature—and the
    doctrine of stare decisis.   Ackelson v. Manley Toy Direct, L.L.C., 
    832 N.W.2d 678
    , 688 (Iowa 2013) (relying on stare decisis and legislative
    acquiescence to adhere to interpretation of the ICRA disallowing punitive
    damages); see also In re Estate of Vajgrt, 
    801 N.W.2d 570
    , 574 (Iowa
    2011) (“The rule of stare decisis ‘is especially applicable where the
    construction placed on a statute by previous decisions has been long
    acquiesced in by the legislature . . . .’ ” (quoting Iowa Dep’t of Transp. v.
    Soward, 
    650 N.W.2d 569
    , 574 (Iowa 2002)).
    Predictability and stability are especially important in employment
    law. Employers must comply with both state and federal law. Human
    resources personnel and supervisors must apply myriad rules and
    regulations in complex situations. Employers and prospective employers
    should be able to rely on our precedents. We would generate significant
    uncertainty if we overrule our own long-standing precedent to diverge
    from settled federal interpretations. Uncertainty invites more litigation
    and increasing costs for all parties.     An uncertain or costly litigation
    environment inhibits job creation.
    The legislative history of the ICRA does not support the view that
    we should depart from our long-standing practice of looking to federal
    decisions to interpret the same or equivalent statutory language. While it
    45
    is true some provisions of the ICRA predated Title VII, 11 the ICRA’s
    retaliation provision was enacted after Title VII and closely tracked the
    federal provision. 12         Accordingly, we appropriately look to federal
    decisions for guidance.             Moreover, other states follow the federal
    causation standard when interpreting their own state antiretaliation
    statutes. 13 Congruity between state and federal requirements makes it
    easier for employers and the bench and bar to apply and follow the law.
    11Iowa   had a statute predating Title VII, a criminal provision, which stated,
    1. Every person in this state is entitled to the opportunity for
    employment on equal terms with every other person. It shall be unlawful
    for any person or employer to discriminate in the employment of
    individuals because of race, religion, color, national origin or ancestry.
    However, as to employment such individuals must be qualified to
    perform the services or work required.
    ....
    3. Any person, employer, labor union or officer of a labor union
    or organization convicted of a violation of subsections one (1) or two (2) of
    this Act shall be punished by a fine not to exceed one hundred dollars or
    imprisonment in the county jail not to exceed thirty days.
    1963 Iowa Acts ch. 330, § 1 (codified at Iowa Code § 735.6 (1966), subsequently
    transferred to section 729.4 (1979)). This statute makes no mention of retaliation.
    12See   1965 Iowa Acts ch. 121, § 8 (codified at Iowa Code § 105A.8 (1966)). The
    Iowa provision used the language in Title VII of the Civil Rights Act of 1964. Compare
    id. § 8(2) (prohibiting retaliation “because such person has lawfully opposed any
    practice forbidden under this Act, obeys the provisions of this Act, or has filed a
    complaint, testified, or assisted in any proceeding under this Act”), with Civil Rights Act
    of 1964, Pub. L. No. 88–352, § 704(a), 78 Stat. 241, 258 (codified as amended at 42
    U.S.C. § 2000e-3(a) (prohibiting retaliation “because he has opposed any practice made
    an unlawful employment practice by this title, or because he has made a charge,
    testified, assisted, or participated in any manner in an investigation, proceeding, or
    hearing under this title”).
    13For example, in Wholf v. Tremco, Inc., the Ohio Court of Appeals applied a
    higher causation standard to a retaliation claim under its own civil rights statute. 
    26 N.E.3d 902
    , 908–09 (Ohio Ct. App. 2015). The Wholf court noted,
    [T]he [Ohio] General Assembly separated status-based discrimination
    claims from retaliation claims in separate subsections of R.C. 4112.02.
    And, despite Wholf’s argument to the contrary, Ohio’s anti-retaliation
    provision is nearly identical to Title VII’s anti-retaliation provision.
    Id. at 908. The court also pointed out that “the ‘but-for’ standard articulated in Nassar
    is not a new standard; it is a clarification of the standard that has been applied in
    46
    We    conclude      the    district    court’s   instruction     applying      the
    motivating-factor causation standard was erroneous. In the marshaling
    instruction for Count II, retaliatory discharge, the district court should
    have instructed the jury that Haskenhoff must prove the protected
    activity was a significant factor motivating the adverse action, consistent
    with our precedent.
    D. Whether the District Court’s Jury Instruction Improperly
    Defined “Adverse Employment Action.” Next, we address whether the
    court’s   instruction      defining    an     adverse    employment        action    was
    erroneous. HES argues the instruction reflected an inaccurate statement
    of the law because it listed the following as examples of adverse action:
    reprimands or threats of reprimands, . . . false accusations
    or complaints, being investigated, being placed on a
    performance improvement plan, being placed on probation,
    or other actions which adversely affect or undermine the

    words, that he would have been treated differently in the absence of the unlawful

    position of the employee[,] . . . an employer seeking out
    negative feedback on an employee, or condoning or
    encouraging other employees to complain about her.
    HES points out that no Iowa court has held these actions are “materially
    adverse actions” for purposes of a retaliation claim under the ICRA.
    In order to prove retaliation, a plaintiff must show “the employer
    took adverse employment action against him or her.” Boyle, 710 N.W.2d
    at 750. We previously held that an adverse employment action is “an
    action that detrimentally affects the terms, conditions, or privileges of
    employment.    Changes in duties or working conditions that cause no
    materially significant disadvantage to the employees are not adverse
    employment actions.” Channon v. United Parcel Serv., Inc., 
    629 N.W.2d 835
    , 862 (2001).   “[A] wide variety of actions, some blatant and some
    subtle, can qualify” as adverse employment actions. Id. at 863 (quoting
    Bryson v. Chi. State Univ., 
    96 F.3d 912
    , 916 (7th Cir. 1996)). Adverse
    action may include “disciplinary demotion, termination, unjustified
    evaluations and reports, loss of normal work assignments, and extension
    of probationary period.” Id. (quoting McKenzie v. Atl. Richfield Co., 
    906 F. Supp. 572
    , 575 (D. Colo. 1995)). We have also concluded that losing a
    prestigious title or opportunity for advancement, physically punching an
    employee, and reducing an employee from full- to part-time can qualify
    as adverse employment actions. See id. at 865 (constructive demotion);
    see also Estate of Harris, 679 N.W.2d at 678 (punching employee in
    chest); City of Hampton, 554 N.W.2d at 536 (reduction of hours).
    Whether an adverse employment action occurred “normally depend[ed]
    on the facts of each situation.” Channon, 629 N.W.2d at 862 (quoting
    Bryson, 96 F.3d at 916); see also Burlington N. & Santa Fe Ry. v. White,
    
    548 U.S. 53
    , 71, 
    126 S. Ct. 2405
    , 2417 (2006) (“[M]aterially adverse
    depends upon the circumstances of the particular case, and ‘should be
    48
    judged from the perspective of a reasonable person in the plaintiff’s
    position, considering “all the circumstances.” ’ ” (quoting Oncale v.
    Sundowner Offshore Servs., Inc., 
    523 U.S. 75
    , 81, 
    118 S. Ct. 998
    , 1003
    (1998))).
    The Supreme Court in Burlington Northern provided further
    guidance on what qualifies as an adverse employment action in a
    retaliation claim.   A female employee, Sheila White, was assigned to
    operate a forklift, a desirable position because it was less arduous and
    cleaner than other tasks. 548 U.S. at 57–58, 126 S. Ct. at 2409. After
    White complained about a male employee harassing her, she was moved
    off forklift duty and reassigned to a more physically demanding position.
    Id. at 58, 126 S. Ct. at 2409.    White filed an EEOC complaint.       Id.
    Shortly thereafter, her supervisor alleged she was insubordinate, and the
    company suspended her without pay for thirty-seven days.       Id.   After
    determining the complaint was unfounded, the company reinstated her
    with backpay. Id.
    Deciding whether White had suffered an adverse employment
    action, the Court declined to limit a retaliatory adverse action to only
    those that “affect the terms and conditions of employment.” Id. at 64,
    126 S. Ct. at 2412–13. This differed from the Court’s interpretation of
    adverse action under the antidiscrimination provision, which only
    prohibited “employment-related” adverse action. Id. at 63, 126 S. Ct. at
    2412. This was because the antidiscrimination provision was intended
    to promote equality in employment opportunities, and therefore, the
    purpose would be achieved “were all employment-related discrimination
    miraculously eliminated.” Id. But the Court recognized the retaliation
    provision’s objective could not likewise be achieved by only prohibiting
    employment-related harms because        “[a]n employer can effectively
    49
    retaliate against an employee by taking actions not directly related to his
    employment or by causing him harm outside the workplace.” Id.
    Thus, the Court took a broader approach, allowing a plaintiff
    alleging an adverse action was “materially adverse” to prove the action
    would have “dissuaded a reasonable worker from making or supporting a
    charge of discrimination.” Id. at 68, 126 S. Ct. at 2415 (quoting Rochon
    v. Gonzales, 
    438 F.3d 1211
    , 1219 (D.C. Cir. 2006)).             The Court
    elaborated,
    We speak of material adversity because we believe it is
    important to separate significant from trivial harms. Title
    VII, we have said, does not set forth “a general civility code
    for the American workplace.” An employee’s decision to
    report discriminatory behavior cannot immunize the
    employee from those petty slights or minor annoyances that
    often take place at work and that all employees experience.
    The antiretaliation provision seeks to prevent employer
    interference with “unfettered access” to Title VII’s remedial
    mechanisms. It does so by prohibiting employer actions that
    are likely “to deter victims of discrimination from
    complaining to the EEOC,” the courts, and their employers.
    And normally petty slights, minor annoyances, and simple
    lack of good manners will not create such deterrence.
    Id. (citations omitted) (first quoting Oncale, 523 U.S. at 80, 118 S. Ct. at
    1002; and then quoting Robinson v. Shell Oil Co., 
    519 U.S. 337
    , 346, 
    117 S. Ct. 843
    , 848 (1997)).
    The Court stressed that the “significance of any given act of
    retaliation will often depend on the particular circumstances.” Id. at 69,
    126 S. Ct. at 2415.        Under this standard, the Court held that
    reassignment to a less desirable job and suspension was an adverse
    employment action. Id. at 71, 126 S. Ct. at 2417. The Court noted,
    Common sense suggests that one good way to discourage an
    employee such as White from bringing discrimination
    charges would be to insist that she spend more time
    performing the more arduous duties and less time
    performing those that are easier or more agreeable.
    50
    Id. at 70–71, 126 S. Ct. at 2416. Still, the Court took pains to recognize
    that “reassignment of job duties is not automatically actionable” and will
    “depend[] upon the circumstances of the particular case.” Id. at 71, 126
    S. Ct. at 2417.     The Court also concluded that although White had
    received backpay for the time of her suspension, it was still adverse
    action because “White and her family had to live for 37 days without
    income. . . . Many reasonable employees would find a month without a
    paycheck to be a serious hardship.” Id. at 72, 126 S. Ct. at 2417. We
    find Burlington Northern persuasive and adopt it as the appropriate
    inquiry for evaluating an adverse employment action under the ICRA.
    Burlington Northern, however, does not rescue the jury instruction
    here.    Even before Burlington Northern, we recognized that adverse
    employment actions can occur in a variety of situations and “will
    normally depend on the facts of each situation.” Channon, 629 N.W.2d
    at 862 (quoting Bryson, 96 F.3d at 916). To the extent that Burlington
    Northern broadened the inquiry to situations that do not directly affect
    the terms or conditions of employment, the jury instruction captured this
    sentiment, defining adverse action as “anything that might dissuade a
    reasonable    person   from   making     or   supporting   an   allegation   of
    discrimination or harassment.” But the instruction went too far when it
    effectively told the jury that reprimands or performance improvement
    plans constituted adverse action as a matter of law. Cases both before
    and after Burlington Northern have consistently held that “a negative
    performance review on its own does not constitute an ‘adverse
    employment action’ . . . unless the review was relied on in making
    promotion decisions about the employee.” Rebouche v. Deere & Co., 
    786 F.3d 1083
    , 1088 (8th Cir. 2015).
    51
    Prior to Burlington Northern, in Farmland Foods, when an employer
    criticized an employee because of the slow pace of his work, we
    determined that “occasional complaints voiced by an employer about
    employee    performance   standards”     did   not   constitute   “substantial
    evidence of a materially adverse employment action.”         672 N.W.2d at
    742.   We explained that the employee’s internal transfer also did not
    qualify as an adverse action because “minor changes in working
    conditions that only amount to an inconvenience cannot support
    discrimination.” Id. We added, “An employment action is not adverse
    merely because the employee does not like it or disagrees with it.” Id.
    Similarly, in Powell v. Yellow Book USA, Inc., although an employee
    received three written reprimands after filing a complaint with the ICRC,
    “she [could] point to no cut in her pay, no reduction in her hours, nor
    any other significant change to the conditions of her employment.” 
    445 F.3d 1074
    , 1079 (8th Cir. 2006).       The Eighth Circuit concluded that
    “formal criticisms or reprimands that do not lead to a change in
    compensation, responsibilities, or other benefits do not constitute an
    adverse employment action under Title VII.” Id. In addition, “placing [an
    employee] on a ‘performance improvement plan,’ without more, [does] not
    constitute an adverse employment action.” Givens v. Cingular Wireless,
    
    396 F.3d 998
    , 998 (8th Cir. 2005) (per curiam).
    A majority of circuits addressing the question have held that a
    reprimand or performance improvement plan, without more, cannot be
    considered an adverse employment action under Burlington Northern.
    See Rebouche, 786 F.3d at 1088; see also Jensen-Graf v. Chesapeake
    Emp. Ins., 616 F. App’x 596, 598 (4th Cir. 2015) (per curiam) (concluding
    denial of professional development course because employee was on
    performance improvement plan was not adverse action under Burlington
    52
    Northern); Barnett v. Athens Reg’l Med. Ctr. Inc., 550 F. App’x 711, 715
    (11th Cir 2013) (per curiam) (“[T]he negative performance evaluation
    would not, by itself, have deterred a reasonable person from making a
    charge of discrimination, especially in this case, where such an
    evaluation, by itself, would not impact his salary or job status.”); Fox v.
    Nicholson, 304 F. App’x 728, 733 (10th Cir. 2008) (per curiam) (applying
    Burlington Northern under Americans with Disabilities Act and finding
    that when employee had lower scores and negative comments on reviews
    but was still in satisfactory range, no adverse employment action);
    Vaughn v. Louisville Water Co., 302 F. App’x 337, 348 (6th Cir. 2008)
    (stating lower performance reviews may only be adverse actions if they
    “significantly impact an employee’s wages or professional advancement”);
    James v. Metro. Gov’t of Nashville, 243 F. App’x 74, 79 (6th Cir. 2007)
    (concluding poor evaluations not adverse action unless “markedly worse
    than earlier ones” and impacted “professional advancement” because
    they would not have dissuaded a reasonable employee from filing a Title
    VII claim).
    Under the facts of this case, the performance improvement plan,
    alone, did not cause Haskenhoff material harm either within the
    workplace or outside of it.    Haskenhoff was never suspended, with or
    without pay. See Burlington N., 548 U.S. at 72, 126 S. Ct. at 2417. Her
    work hours were not reduced, nor was her pay cut. The performance
    improvement plan did not affect her professional advancement. See id.
    at 69, 126 S. Ct. at 2416. Her duties and status remained unchanged,
    both within the workplace and outside of it.       Under her performance
    improvement plan, Haskenhoff was only required to abide by rules
    applicable to others in her position. See Fischer v. Andersen Corp., 
    483 F.3d 553
    ,   556–58   (8th   Cir.   2007)   (holding   that   placement   on
    53
    performance improvement plan was not a constructive discharge when
    employee acknowledged that plan requirements “were largely fair and in
    conformance with what one would expect from an engineer”). 14
    Moreover, Finke and Wendland assured Haskenhoff that if she wanted
    any revisions, the plan would be changed to reflect her concerns. The
    timing of the plan and allegations giving rise to it were suspect, but these
    factors were for the jury to weigh under a correct instruction.                          The
    district court erred by instructing the jury the performance improvement
    plan was an adverse employment action as a matter of law.
    “We have on a number of occasions found instructions that unduly
    emphasized certain evidence were flawed and required reversal.” Alcala,
    880 N.W.2d at 710 (quoting Burkhalter v. Burkhalter, 
    841 N.W.2d 93
    ,
    106 (Iowa 2013)).         Jury instructions should not comment on specific
    evidence or erroneously advise the jury “that certain facts are undisputed
    when there is conflicting evidence on the question.”                          Locksley v.
    Anesthesiologists of Cedar Rapids, P.C., 
    333 N.W.2d 451
    , 455 (Iowa
    1983); see also 89 C.J.S. Trial § 581, at 36 (2012) (“[I]mpermissible
    comments in jury instructions include those where the court assumes
    the truth of a material controverted fact or . . . withdraws some pertinent
    evidence from the jury’s consideration.”). For example, in Locksley, we
    upheld a district court’s refusal to give a jury instruction that defendant
    was competent as a matter of law because his competence was disputed,
    14The    performance improvement plan stated Haskenhoff must abide by the
    following: (1) not “walk[] off the job and abandon [her] job responsibilities”; (2) not “us[e]
    vulgar language towards another”; (3) not “send[] hostile, disrespectful, or inappropriate
    emails to employees”; (4) not “post[] comments about the company or other employees
    on a social network”; (5) go through the chain of command rather than “address[ing] the
    problem [her]self”; (6) attend work during the “core work hours of 8AM to 4PM” and
    “approv[e] ahead of time” coming in or leaving early; (7) not leave the plant “during the
    work day for non-work related reasons”; and (8) approve paid time off “ahead of time.”
    54
    and the proposed instruction would have taken a factual determination
    from the jury. 333 N.W.2d at 455.
    Instruction No. 30 provided that certain activities constituted
    adverse employment actions as a matter of law.                 The list included
    matters that no court in Iowa—or the Iowa Civil Rights Commission or
    EEOC,    for   that   matter—has     concluded         constitute   an   adverse
    employment action as a matter of law. See EEOC Enforcement Guidance
    on   Retaliation   and   Related    Issues     (Aug.     25,   2016),    https://
    www.eeoc.gov/laws/guidance/retaliation-guidance.cfm#_ftnref113.               By
    stating certain instances of conduct that occurred in this case were
    examples of adverse employment actions (and thus adverse action as a
    matter of law), the instruction took that factual determination away from
    the jury and relieved Haskenhoff of her burden of proof on that element
    of the retaliation claim.   See Anderson, 620 N.W.2d at 267 (providing
    examples of breaches of duty of care in negligence action takes
    determination away from the jury because jury must be the one to apply
    the legal standard to the facts).         We conclude the adverse-action
    instruction misstated the law and unduly emphasized certain evidence.
    This prejudicial error requires a new trial.
    E. Whether the Constructive Discharge Instruction Misstated
    the Law. We next address the district court’s instruction on constructive
    discharge. “Constructive discharge exists when the employer deliberately
    makes an employee’s working conditions so intolerable that the employee
    is forced into an involuntary resignation.”               Van Meter Indus. v.
    Mason City Human Rights Comm’n, 
    675 N.W.2d 503
    , 511 (Iowa 2004)
    (quoting First Judicial Dist. Dep’t of Corr. Servs. v. Iowa Civil Rights
    Comm’n, 
    315 N.W.2d 83
    , 87 (Iowa 1982)). The policy behind constructive
    discharge is simple: an employer “should not be able to accomplish
    55
    indirectly what the law prohibits directly.”    1 Barbara T. Lindemann
    et al., Employment Discrimination Law 21-33 (5th ed. 2012) [hereinafter
    Lindemann].
    In an attempt to avoid liability, an employer may refrain from
    actually firing an employee, preferring instead to engage in
    conduct causing him or her to quit.           The doctrine of
    constructive discharge addresses such employer-attempted
    “end runs” around wrongful discharge and other claims
    requiring employer-initiated terminations of employment.
    Balmer v. Hawkeye Steel, 
    604 N.W.2d 639
    , 641 (Iowa 2000) (quoting
    Turner v. Anheuser-Busch, Inc., 
    876 P.2d 1022
    , 1025 (Cal. 1994)
    (en banc)). Employees often allege discriminatory constructive discharge
    because it allows recovery of backpay. Van Meter Indus., 675 N.W.2d at
    510–11. “[T]rivial or isolated acts of the employer are not sufficient to
    support a constructive discharge claim.”       Id. at 511.    “Rather, the
    ‘working conditions must be unusually “aggravated” or amount to a
    “continuous pattern” before the situation will be deemed intolerable.’ ”
    Id. (quoting Haberer v. Woodbury County, 
    560 N.W.2d 571
    , 576 (Iowa
    1997)). Constructive discharge is not its own cause of action, but must
    be asserted under a common law or statutory framework, such as the
    Iowa Civil Rights Act.   See Balmer, 604 N.W.2d at 642 (outlining that
    constructive discharge can be a form of wrongful discharge or asserted
    under statute allowing recovery). As such, it can either be alleged under
    a discrimination claim (“The employer made my working conditions
    intolerable by discriminating on the basis of an unfair characteristic.”),
    or as an adverse action under a retaliation theory (“The employer
    retaliated against me by making my working conditions intolerable.”). As
    is the case here, “[c]onstructive discharge, like any other discharge, is an
    adverse employment action that will support an action for unlawful
    56
    retaliation.” West v. Marion Merrell Dow, Inc., 
    54 F.3d 493
    , 497 (8th Cir.
    1995).
    HES asserts three errors in the constructive discharge instruction.
    First, HES contends that it was error to instruct the jury, “The employer
    need not really want the employee to quit.”      Second, HES argues the
    district court erred by inserting a subjective standard into the definition
    of constructive discharge. Third, HES assigns error to the district court’s
    refusal to allow an instruction stating “conditions will not be considered
    intolerable unless the employer has been given a reasonable chance to
    resolve the problem.”
    1. Employer need not want the employee to quit.         We conclude
    there was no error in the district court’s instruction on the principle that
    “[t]he employer need not really want the employee to quit.” In Van Meter
    Industries, Jane Sires quit her job with Van Meter Industries after being
    passed over for a promotion and “relegated to the operations side of the
    business where there was no reasonable likelihood of advancement into a
    manager position” because of her sex.        675 N.W.2d at 511.         Sires
    conceded she did not think Van Meter Industries “really wanted her to
    quit.” Id. at 512. We stated,
    Although it may be undisputed that VMI wanted Sires to
    stay on the job, this fact does not preclude a finding that the
    company deliberately rendered Sires’ working conditions so
    intolerable that a reasonable employee in Sires’ position
    would resign.
    Id.   It is enough “that the employee’s resignation was a reasonably
    foreseeable consequence of the insufferable working conditions created
    by the employer.” Id. We reversed the district court’s finding there was
    not substantial evidence Sires was constructively discharged. Id. at 513.
    Pursuant to Van Meter Industries, the jury was correctly instructed the
    57
    employer need not really want the employee to quit to claim constructive
    discharge.
    2. Objective standard for constructive discharge. HES next asserts
    error because the constructive discharge instruction wrongly directed the
    jury to consider a subjective standard.       The instruction stated, “The
    employee must show that she was subjected to sexual harassment or
    retaliation [that] made her believe there was no chance for fair treatment
    at Homeland.”    (Emphasis added.)       We conclude it should have said,
    “made her reasonably believe.”
    The test for constructive discharge is objective, evaluating whether
    a reasonable person in the employee’s position would have been
    compelled to resign and whether an employee reasonably believed there
    was no possibility that an employer would respond fairly.      Id. at 511.
    “The issue thus is not how plaintiff felt but whether a reasonable person
    in his position would have felt the same way.” Reihmann v. Foerstner,
    
    375 N.W.2d 677
    , 683 (Iowa 1985).
    “[W]orking conditions must be unusually ‘aggravated’ or amount to
    a ‘continuous pattern’ before the situation will be deemed intolerable.”
    Van Meter Indus. 675 N.W.2d at 511 (quoting Haberer, 560 N.W.2d at
    576). In Haberer, a police officer resigned after he was placed on a paid,
    eighteen-month suspension followed by an unpaid thirty-day suspension
    pending a criminal investigation against him. 560 N.W.2d at 573. When
    the officer returned to duty, he was reassigned to office work. Id. After
    receiving notice his wages would be garnished for unpaid child support,
    the officer resigned. Id. We held, as a matter of law, no constructive
    discharge had occurred.    Id. at 578.    Haberer’s reassignment to office
    work was not “(1) a change in grade, (2) inconsistent with or outside the
    scope of his job description, (3) a decrease in pay or prestige, (4)
    58
    impossible to do, or (5) anything beyond a mere ‘difficulty’ because of a
    lack of ‘experience.’ ” Id. at 577. We noted,
    Under the cases, an employee cannot simply “quit and sue,”
    claiming he or she was constructively discharged. The
    conditions giving rise to the resignation must be sufficiently
    extraordinary and egregious to overcome the normal
    motivation of a competent, diligent, and reasonable employee
    to remain on the job to earn a livelihood and to serve his or
    her employer. . . .
    . . . Every job has its frustrations, challenges, . . . and
    disappointments; these inhere in the nature of work. [An
    employee is not] guaranteed a working environment free of
    stress.
    Id. at 575–76 (alteration in original) (quoting Turner, 876 P.2d at 1026–
    27).
    The first paragraph of the constructive discharge instruction
    focused on whether the conditions were “intolerable so that the employee
    reasonably feels forced to quit.” But the second paragraph implied that
    “intolerable” conditions equated to the employee’s subjective belief there
    was “no chance for fair treatment at Homeland.” This was not a correct
    statement of law. See Van Meter Indus., 675 N.W.2d at 511–12 (stating
    that constructive discharge results when “employee has no recourse
    within the employer’s organization or ‘reasonably believes there is no
    chance for fair treatment’ ” (emphasis added) (citation omitted) (quoting
    Kimzey v. Wal-Mart Stores, Inc., 
    107 F.3d 568
    , 574 (8th Cir. 1997))).
    Nevertheless, omitting “reasonably” in one sentence of the
    constructive discharge instruction was harmless when the instructions
    are read as a whole. “[W]e look to the instructions as a whole and do not
    require perfection.”   Rivera, 865 N.W.2d at 902.        Another instruction
    stated,
    59
    INSTRUCTION NO. 34
    INTOLERABLE WORKING CONDITIONS – DEFINED
    Working conditions are intolerable if a reasonable
    person in the plaintiff’s situation would have deemed
    resignation the only reasonable alternative.
    The conditions giving rise to the resignation must be
    sufficiently extraordinary and egregious to overcome the
    normal motivation of a competent, diligent and reasonable
    employee to remain on the job to earn a livelihood and to
    serve his or her employer.
    The adverse working conditions must be unusually
    “aggravated” or amount to a “continuous pattern” before the
    situation will be deemed intolerable. A single, trivial or
    isolated act is insufficient to support a constructive
    discharge claim.
    The instructions on constructive discharge mentioned the standard of
    “reasonable belief” or “reasonable employee” no less than five times. In
    addition, the sentence immediately following the offending statement in
    the marshaling instruction clarified the objective standard, elaborating
    that the employee must “reasonably believe” there is no possibility of fair
    treatment. Reading the instructions together “leads to the inevitable
    conclusion the jury could not have misapprehended the issue” on the
    constructive discharge objective standard.       Moser v. Stallings, 
    387 N.W.2d 599
    , 605 (Iowa 1986).
    3. Reasonable chance to resolve the problem. HES raises a final
    point that the district court should have given its requested instruction
    stating that “conditions cannot be considered intolerable unless the
    employer has been given a reasonable chance to resolve the problem.”
    We conclude HES’s requested instruction was a correct statement of the
    law and was not adequately embodied in other instructions. Therefore,
    on this record, it was reversible error for the district court to refuse to
    give that instruction.
    In Van Meter Industries, we squarely decided that an employee
    must give an employer “a reasonable chance to resolve the problem.”
    60
    675 N.W.2d at 511. Sires reported to one of her superiors and to the
    director of human resources before resigning that she felt she “ ‘had
    reached [the] highest level [she] was going to be allowed to go’ and that
    she was considering resigning.” Id. at 508 (alterations in original). Her
    superior asked her to “wait,” and the human resources director told her
    to “hang in there.” Id. A week passed with no response. Id. Sires then
    received a phone call in which she was given “vague reassurance[s]” and
    informed that if the individual who made the promotion decision “had it
    to do over again, he would still promote [the male employee] over her.”
    Id. Sires resigned two days later, and Van Meter Industries accepted her
    resignation without protest. Id. The commission found that Sires had
    been constructively discharged. Id. at 509. The district court reversed,
    believing “Sires had not given VMI ‘any opportunity to work on the
    problem before she quit,’ ” among other reasons. 15 Id. at 510.
    On review, we began by noting that “conditions will not be
    considered intolerable unless the employer has been given a reasonable
    chance to resolve the problem.”          Id. at 511.     We then tempered this
    statement: “On the other hand, an employee need not stay if he or she
    reasonably believes there is no possibility the employer will respond
    fairly.” Id. Examining Sires’ constructive discharge claim, we observed
    she gave Van Meter Industries a reasonable opportunity to remedy the
    discrimination. Id. at 513. Although she waited only one month before
    15It   has been suggested our decision in Van Meter Industries was not
    precedential on this point. However, whether Sires could recover without giving the
    employer a “reasonable opportunity to resolve the problem” was a fighting issue. That
    was the basis for the district court’s reversal of the commission’s decision. See
    Van Meter Indus., 675 N.W.2d at 510. We recognized the defendant employer “claim[ed]
    Sires failed to give the company an adequate opportunity to address her grievances and
    so cannot rely on the constructive discharge doctrine.” Id. at 513. We addressed that
    claim, spending almost a full page on the discussion. Id.; see also Ackelson, 832
    N.W.2d at 688 (“We are slow to depart from stare decisis and only do so under the most
    cogent circumstances.”).
    61
    quitting, Sires had a reasonable belief her employer would not resolve the
    problem:
    In the weeks between Meyers’ promotion and Sires’
    resignation the company not only took no action to
    investigate Sires’ complaints, it gave no indication that it
    intended to conduct an inquiry. The company’s indifference
    was further demonstrated by the fact Sires was referred to
    the individual who made the discriminatory promotion
    decision to seek a resolution of her grievance.        This
    individual, rather than assuring Sires that appropriate and
    prompt remedial action would be taken, informed her that he
    would make the same decision again if he had it to do over
    and reaffirmed that the company saw her future in
    operations.
    Id. (citation omitted).   Because Sires demonstrated a reasonable belief
    her employer would not resolve the problem, we concluded,
    [W]e cannot say under the specific circumstances of this
    particular case that she acted precipitously. A review of the
    evidence shows this case is not one where the company did
    not have sufficient time to rectify its wrong. . . . Rather, this
    case presents a situation where the company, when given
    the opportunity, chose to perpetuate its discriminatory
    practices.
    Id.
    We supported our decision by citing Iowa precedent and precedent
    from the Eighth Circuit.      See id. at 511 (citing Breeding v. Arthur J.
    Gallagher & Co., 
    164 F.3d 1151
    , 1159 (8th Cir. 1999), abrogated in part
    on other grounds by Torgerson v. City of Rochester, 
    643 F.3d 1031
    , 1043
    (8th Cir. 2011); First Judicial Dist. Dep’t of Corr. Servs., 315 N.W.2d at
    89).   In First Judicial District Department of Correctional Services, we
    denied recovery on a race and disability constructive discharge claim
    when the department of corrections issued an order restricting an
    African-American blind counselor’s access to the jail due to a security
    risk. 315 N.W.2d at 85. The employee quit one day later. Id. We held
    the employee “was precipitous; she overreacted.” Id. at 89. She “failed to
    62
    make a good faith effort to determine whether the restriction from the jail
    would render her employment as onerous as she now contends,” and the
    record contained nothing showing the restriction was permanent.             Id.
    Her   “immediate   resignation     ...   deprived   [the   employer]   of   the
    opportunity to investigate and remedy the situation.”           Id.; see also
    Haberer, 560 N.W.2d at 577 (denying recovery based in part on
    employee’s “rash and intemperate” act of resigning); cf. Johnson v. Dollar
    Gen., 
    880 F. Supp. 2d 967
    , 998 n.6 (N.D. Iowa 2012) (“[T]he Iowa
    Supreme Court has observed that ‘conditions will not be considered
    intolerable [so as to constitute constructive discharge] unless the
    employer has been given a reasonable chance to resolve the problem,’
    and Johnson gave Dollar General and Williams no such opportunity
    before resigning.” (alteration in original) (citation omitted) (quoting
    Van Meter Indus., 675 N.W.2d at 511)), aff’d, 508 F. App’x 587 (8th Cir.
    2013).
    The Eighth Circuit has held that to demonstrate constructive
    discharge, an employee must show that a “reasonable person would find
    the working conditions intolerable.” Phillips v. Taco Bell Corp., 
    156 F.3d 884
    , 890 (8th Cir. 1998).        “Such intolerability . . . is judged by an
    objective standard, not the plaintiff’s subjective feelings.”    Id.   “To act
    reasonably, an employee has an obligation not to assume the worst and
    not to jump to conclusions too quickly.”       Tidwell v. Meyer’s Bakeries,
    Inc., 
    93 F.3d 490
    , 494 (8th Cir. 1996). Thus, “[a]n employee who quits
    without giving [the] employer a reasonable chance to work out a problem
    has not been constructively discharged.” Id. Indeed, “passivity in the
    face of working conditions alleged to be intolerable is often inconsistent
    with the allegation.” Lindale v. Tokheim Corp., 
    145 F.3d 953
    , 955 (7th
    Cir. 1998). But “[i]f an employee quits because she reasonably believes
    63
    there is no chance for fair treatment, there has been a constructive
    discharge.” Kimzey, 107 F.3d at 574.
    Peggy    Kimzey,   an    employee   at   Wal-Mart,   complained   to
    management several times about repeated harassment by her supervisor.
    Id. at 571.   Management told her they were aware of the problem but
    took no action to investigate or follow up on the complaint. Id. Even
    after Kimzey resigned because of her supervisor’s continued conduct, her
    manager “did not indicate that he would investigate her complaints or
    take any other action required by Wal-Mart’s open door policy.” Id. at
    572. The Eighth Circuit held that “[a] reasonable jury could find that the
    continuing    harassment      and   management’s   indifference   rendered
    Kimzey’s working conditions intolerable and forced her to quit.” Id. at
    574–75.   It highlighted the evidence that members of Wal-Mart knew
    Kimzey was being harassed, but “generally ignored those complaints.”
    Id. at 574. Because Kimzey demonstrated a reasonable belief there was
    no chance of fair treatment at Wal-Mart, the Eighth Circuit found no
    error in submitting the constructive discharge claim to the jury. Id. at
    575; see also Sanders v. Lee Cty. Sch. Dist. No. 1, 
    669 F.3d 888
    , 894 (8th
    Cir. 2012) (finding discriminatory constructive discharge claim supported
    when employee reasonably believed no chance for fair treatment because
    employer failed to respond to repeated requests for information about
    reassignment); Henderson v. Simmons Foods, Inc., 
    217 F.3d 612
    , 617
    (8th Cir. 2000) (affirming constructive discharge claim when employee
    “essentially is left with no choice other than the termination of her
    employment” due to employer’s failure to investigate or respond to
    knowledge of harassment).
    By contrast, in Alvarez v. Des Moines Bolt Supply, Inc., the Eighth
    Circuit held the district court properly granted summary judgment on a
    64
    constructive discharge claim when an employee failed to notify the
    employer of retaliatory harassment. 
    626 F.3d 410
    , 418 (8th Cir. 2010).
    Veronica Alvarez notified her employer of inappropriate sexual conduct
    by her coworker. Id. at 413–14. Her employer investigated the claims
    and suspended the harassing coworker.                 Id. at 415.    Other coworkers
    then began to harass her in retaliation for her complaint. Id. However,
    Alvarez       failed   to   notify   the   employer    about   the    postsuspension
    harassment before she resigned.              Id.   The Eighth Circuit concluded
    Alvarez had given her employer “no reasonable opportunity to remedy the
    problem.” Id. at 419. Alvarez argued she should be excused from the
    notice requirement because her prior complaint showed she “had no
    chance for fair treatment if she complained again about harassment.” Id.
    But “[p]art of an employee’s obligation to be reasonable,” the court held,
    “is an obligation not to assume the worst, and not to jump to conclusions
    too fast.”      Id. (quoting Smith v. Goodyear Tire & Rubber Co., 
    895 F.2d 467
    , 473 (8th Cir. 1990)).           Thus, her prior complaint “did not excuse
    Alvarez from at least notifying DMB about the continued misconduct to
    see how the company would respond.” Id.
    Other cases have similarly held, unless the employee demonstrates
    a reasonable belief there is no chance for fair treatment, he or she must
    give the employer a chance to respond before resigning due to retaliatory
    conduct. 16       See Phillips, 156 F.3d at 891 (determining employee not
    16Ithas been suggested giving the employer a reasonable chance to resolve the
    problem “is another effort to transplant” the Faragher–Ellerth defense. However, this
    assertion overlooks that the Faragher–Ellerth defense has already been held to apply to
    certain instances of constructive discharge. See Pa. State Police v. Suders, 
    542 U.S. 129
    , 141, 
    124 S. Ct. 2342
    , 2351 (2004) (stating absent a “tangible employment action,”
    the defense “is available to the employer whose supervisors are charged with
    harassment” resulting in constructive discharge); see also id. at 150–51 & n.10, 124
    S. Ct. at 2356 & n.10 (noting Eighth Circuit and other caselaw analyzing whether
    “employee’s decision to resign was reasonable under the circumstances” specifically
    65
    constructively discharged when manager retaliated against her by
    speaking to her in “nasty” tone because she “fail[ed] to give Taco Bell a
    fair opportunity to demonstrate that it had remedied the situation”);
    Coffman v. Tracker Marine, L.P., 
    141 F.3d 1241
    , 1247–48 (8th Cir. 1998)
    (holding    employee     was     not   constructively    discharged      when    she
    complained about retaliation but failed to give the employer’s method for
    solving the problem a chance); Tidwell, 93 F.3d at 496 (concluding
    employee who quit the day after seeing allegedly retaliatory schedule
    change not constructively discharged because he failed to give employer
    “an opportunity to explain the situation or remedy it”).               Such a rule
    recognizes that “a reasonable waiting period is inversely related to the
    severity of the situation,” Watson v. Heartland Health Labs., Inc., 
    790 F.3d 856
    , 864 (8th Cir. 2015), and there may be cases of severe
    harassment or retaliation when it is reasonable for the employee to
    resign immediately. It also acknowledges there may be times when the
    _________________________
    consider whether the employer was given “a chance to respond” (first quoting Suders v.
    Easton, 
    325 F.3d 432
    , 462 (3d Cir. 2003); and then quoting Jaros v. LodgeNet, Entm’t
    Corp., 
    294 F.3d 960
    , 965 (8th Cir. 2002))).
    Principles of deterrence and avoidance undergird theories of employment
    liability. See Sara Kagay, Applying the Ellerth Defense to Constructive Discharge: An
    Affirmative Answer, 
    85 Iowa L
    . Rev. 1035, 1061 (2000) (“The purpose of Title VII is to
    encourage anti-harassment policies, promote conciliation, and prevent harassment.”).
    These principles are evident in both the doctrine of constructive discharge and the
    Faragher–Ellerth defense. See Shari M. Goldsmith, The Supreme Court’s Suders Problem:
    Wrong Question, Wrong Facts Determining Whether Constructive Discharge Is a Tangible
    Employment Action, 6 U. Pa. J. Lab. & Emp. L. 817, 837–37 (2004) (“By emphasizing the
    employee’s obligation to seek redress and the employer’s duty to avoid harm, the
    dominant approach to constructive discharge goes to the heart of the Court’s
    Ellerth/Faragher motivations and purpose.”).
    If the victim could have avoided harm, no liability should be found
    against the employer who had taken reasonable care, and if damages
    could reasonably have been mitigated no award against a liable employer
    should reward a plaintiff for what her own efforts could have avoided.
    Faragher, 524 U.S. at 807, 118 S. Ct. at 2292.
    66
    employee can demonstrate a complaint would be fruitless, such as when
    the prescribed method of recourse is through the alleged harasser or
    when an employer has failed to respond to previous instances of
    harassment. See, e.g., Van Meter Indus., 675 N.W.2d at 513 (“Sires was
    referred to the individual who made the discriminatory promotion
    decision to seek a resolution of her grievance.”).
    “[A]ntidiscrimination policies are better served when the employee
    and employer attack discrimination within their existing employment
    relationship, rather than when the employee walks away and then later
    litigates whether his employment situation was intolerable.”       Poland v.
    Chertoff, 
    494 F.3d 1174
    , 1184 (9th Cir. 2007). We empathize with the
    fact that in many cases coming forward with allegations of retaliation
    may seem difficult. See Cathy Shuck, That’s It, I Quit: Returning to First
    Principles in Constructive Discharge Doctrine, 23 Berkeley J. Emp. & Lab.
    L. 401, 429–30 (2002) (“The most frequently cited reason for failing to
    report harassment is fear of negative outcomes—fear that the employee
    will lose her job, not be believed, or ‘simply because it will not help [her]
    situation[].’ ” (alterations in original) (quoting Theresa M. Beiner, Sex,
    Science and Social Knowledge: The Implications of Social Science Research
    on Imputing Liability to Employers for Sexual Harassment, 7 Wm. & Mary
    J.   Women    &   L.   273,   317   (2001))).   But   countervailing   policy
    considerations counsel us the burden placed on the employee is
    reasonable. A preeminent treatise on employment law explains,
    Courts generally require that the employee must give
    higher levels of management the opportunity to correct an
    adverse situation before quitting and claiming constructive
    discharge. The evident purpose of the requirement is to
    allow the employer as an entity—as opposed to, for example,
    an individual (and perhaps aberrational) supervisor—to
    redress the problem.     However, to avoid a finding of
    constructive discharge, the employer’s response must be
    67
    adequate; the employee need              not    suffer     prolonged
    harassment or discrimination.
    Lindemann, at 21-44 to 21-45 (footnotes omitted).                 Moreover, an
    employee can escape the requirement of coming forward by alleging there
    would have been no “chance for fair treatment” in the face of a
    complaint. Kimzey, 107 F.3d at 574.
    Courts     have   consistently    required     “something        more”   for
    constructive discharge claims than for ordinary discrimination or
    retaliation.   Pa. State Police v. Suders, 
    542 U.S. 129
    , 147, 
    124 S. Ct. 2342
    , 2354 (2004).      Constructive discharge occurs when the working
    conditions deteriorate, as a result of discrimination or retaliation, “to the
    point that they become ‘sufficiently extraordinary and egregious to
    overcome the normal motivation of a competent, diligent, and reasonable
    employee to remain on the job to earn a livelihood and to serve his or her
    employer.’ ”   Brooks v. City of San Mateo, 
    229 F.3d 917
    , 930 (9th Cir.
    2000) (quoting Turner, 876 P.2d at 1026).            These discriminatory or
    retaliatory actions are best handled within the employment relationship.
    Poland, 494 F.3d at 1184. The employee can recover for any additional
    acts of harassment suffered until he resigns. See Green v. Brennan, 
    578 U.S.
    ___, ___, 
    136 S. Ct. 1769
    , 1782 (2016) (holding the claim of
    constructive discharge does not accrue until an employee resigns).
    The First, Fifth, Seventh, Eighth, Tenth, and Eleventh Circuits
    consider whether the employee reasonably gave the employer an
    opportunity to respond before claiming constructive discharge. See, e.g.,
    EEOC v. Kohl’s Dep’t Stores, Inc., 
    774 F.3d 127
    , 134 (1st Cir. 2014)
    (holding employee failed to meet “reasonable person” element when her
    “choice to resign was ‘grossly premature, as it was based entirely on [her]

    , 501 (Mo. Ct.
    App. 2013) (“Reasonableness requires an employee not to assume the
    69
    worst, and not to jump to conclusions too quickly.”). 17 As Lindemann
    states,
    The general rule is that a reasonable employee must remain
    and fight discrimination on the job. Indeed, even when the
    employee is faced with what he anticipates will be an
    intolerable job environment, courts generally hold that the
    employee should not quit precipitously, but rather should
    remain to see whether those fears in fact do materialize.
    Moreover, an employee cannot simply speculate that
    intolerable conditions will develop, that an impending
    discharge will occur, or that management will ignore the
    problem.
    Lindemann, at 21-41 to 21-42 (footnotes omitted).
    Haskenhoff failed to establish as a matter of law that it would have
    been fruitless to give HES management more time to respond.                           To
    contrary, HES was actively engaged in responding to her complaint when
    she quit.     It was for the jury to decide, under proper instructions,
    whether she jumped the gun, or rather, was constructively discharged. A
    reasonable employee has “an obligation not to assume the worst and not
    to jump to conclusions too quickly.”             Brenneman, 507 F.3d at 1144
    (quoting Duncan v. Gen. Motors Corp., 
    300 F.3d 928
    , 935 (8th Cir. 2002)).
    17In Missouri, a previous case held an employee did not have to allow a
    reasonable opportunity to respond before claiming constructive discharge. See Pollock
    v. Wetterau Food Distribution Grp., 
    11 S.W.3d 754
    , 761, 765–66 (Mo. Ct. App. 1999).
    That case has been undermined by later cases holding a constructive discharge does
    not occur “without giving the employer a reasonable chance to resolve the problem.”
    DeWalt, 398 S.W.3d at 501; see also Gamber v. Mo. Dep’t of Health & Senior Servs., 
    225 S.W.3d 470
    , 479 (Mo. Ct. App. 2007). Other states considering whether an employee
    gave the employer a reasonable opportunity to respond include West Virginia,
    Nebraska, and Minnesota. Waldron v. Lyman Lumber Co., No. A10–997,

    it was simply one rational option for the employee.”                    Haberer, 560

    Instruction No. 33 omitted language requested by HES and

    employer “a reasonable chance to resolve the problem.”                      Van Meter
    Indus., 675 N.W.2d at 511. That omission constituted prejudicial error.
    F. Whether the Expert Testimony of Dr. Fitzgerald Should
    Have Been Excluded. Because the issue is likely to arise on remand, we
    will discuss whether the district court abused its discretion by allowing
    the testimony of Dr. Fitzgerald.         Iowa Rule of Evidence 5.702 (2014)18
    provides,
    If scientific, technical, or other specialized knowledge will
    assist the trier of fact to understand the evidence or to
    determine a fact in issue, a witness qualified as an expert by
    knowledge, skill, experience, training, or education may
    testify thereto in the form of an opinion or otherwise.
    HES argues expert testimony by Dr. Fitzgerald should not have been
    admitted because it “invade[s] the province of the court to determine the
    applicable law and to instruct the jury as to that law.”                 In re Det. of
    Palmer, 
    691 N.W.2d 413
    , 419 (Iowa 2005) (quoting Torres v. County of
    Oakland, 
    758 F.2d 147
    , 150 (6th Cir. 1985)), overruled on other grounds
    by Alcala, 880 N.W.2d at 708 n.3.                    HES specifically objects to
    Dr. Fitzgerald’s testifying to “the requirements and standards for an
    18Iowa   Rule of Evidence 5.702 has since been amended and now reads,
    A witness who is qualified as an expert by knowledge, skill, experience,
    training, or education may testify in the form of an opinion or otherwise
    if the expert’s scientific, technical, or other specialized knowledge will
    help the trier of fact to understand the evidence or to determine a fact in
    issue.
    Iowa R. Evid. 5.702 (2017).
    71
    effective sexual harassment program and whether [HES]’s harassment
    prevention   and   remediation    program   was   consistent   with   those
    standards.” HES also objects to Dr. Fitzgerald’s testimony about what a
    reasonable company would do. Haskenhoff states that Dr. Fitzgerald’s
    testimony provided helpful insight based on reasonable industry
    standards and did not delve into instruction upon the law.
    HES’s challenge to Dr. Fitzgerald’s testimony focused on the
    linkage to erroneous jury instructions.     Because we are reversing and
    ordering a new trial based on the instructional errors, the admissibility of
    her testimony will be in a somewhat different context on remand. We
    review the general parameters of expert testimony.
    “An opinion is not objectionable just because it embraces an
    ultimate issue.” Iowa R. Evid. 5.704 (2017). We favor a “liberal view on
    the admissibility of expert testimony.”      Ranes, 778 N.W.2d at 685.
    Whether an opinion should be excluded on the basis that it is couched in
    legal terms “depends on ‘whether the terms used by the witness have a
    separate, distinct and specialized meaning in the law different from that
    present in the vernacular.’ ”    In re Det. of Palmer, 691 N.W.2d at 420
    (quoting Torres, 758 F.2d at 151).        If so, the testimony should be
    excluded. Id. For example, questions such as whether a defendant was
    negligent or not negligent are improper because “[e]xperts are not to state
    opinions as to legal standards.”    Iowa R. Evid. [5.]704 committee cmt.
    (1983).
    The district court allowed Dr. Fitzgerald’s testimony, finding she
    was “qualified as an expert on the subjects presented, as provided by
    Iowa Rule of Evidence 5.702.” Dr. Fitzgerald testified she was hired for
    two reasons: (1) to speak with Haskenhoff and evaluate whether she
    displayed typical victim behavior in response to harassment, and (2) to
    72
    examine HES’s policies and procedures on sexual harassment and opine
    whether they met accepted standards in the field of human resources.
    She opined that Haskenhoff suffered from major depressive disorder and
    posttraumatic stress disorder, described these conditions for the jury,
    and stated why they may be caused by harassing behavior. She testified
    about whether this was common for victims of harassment.         She also
    testified about what a “reasonable” company should do to prevent sexual
    harassment according to human resources standards and whether HES
    conformed to those standards. She skirted close to the line prohibiting
    testimony on legal conclusions:
    A. . . . [T]here’s a distinction between—that I should make
    here—between violation of a company’s policy and violation
    of the law.
    Because they’re not—although there’s a great deal of
    overlap, they’re not always exactly the same. So there are
    things that can violate a company’s policy and not violate the
    law. . . .
    ....
    Q. Okay. “The standard of professional practice says
    an investigation,” and then you set out steps a competent
    investigator would take in order to conduct a real
    investigation into this or any other matter. And what are
    those steps? A. Well, I probably should have said “should”
    instead of must, because it’s not the law or anything. But
    the common practice recommendation . . . .
    ....
    Q. And your testimony doesn’t purport to tell the
    jurors what the law is proscribing sex harassment, does it?
    A. No, I do not speak to legal issues.
    Testimony that particular conduct violated the ICRA clearly would be an
    inadmissible legal conclusion.
    Expert testimony on the standard of care or standard of practice is
    generally permitted in negligence actions. See Alcala, 880 N.W.2d at 709
    (collecting cases requiring evidence of an employer’s standard of care and
    73
    its breach to recover under a negligent-training theory); Oswald v.
    LeGrand, 
    453 N.W.2d 634
    , 635 (Iowa 1990) (noting that in a professional
    negligence action, “[o]rdinarily, evidence of the applicable standard of
    care—and its breach—must be furnished by an expert”); Brandt v.
    Richter, 
    159 N.W.2d 471
    , 474 (Iowa 1968) (allowing testimony of farm
    safety expert and       discussing precedent rejecting argument such
    testimony improperly altered the standard of care). But expert testimony
    as to a legal conclusion is inadmissible in an ordinary negligence action.
    See, e.g., Bell v. Cmty. Ambulance Serv. Agency, 
    579 N.W.2d 330
    , 338
    (Iowa 1998) (affirming exclusion of opinion testimony of law enforcement
    trainer that ambulance driver’s “actions were highly dangerous and likely
    to cause injury”); Terrell v. Reinecker, 
    482 N.W.2d 428
    , 430 (Iowa 1992)
    (holding it was reversible error to allow investigating police officer to
    testify to the legal conclusion that plaintiff “failed to yield the right-of-
    way”).     We have not previously decided where the line is drawn in a
    hostile-work-environment case. We conclude the district court did not
    abuse its discretion in allowing Dr. Fitzgerald’s testimony on the record
    made at the first trial.
    IV. Disposition.
    For those reasons, we reverse the district court’s ruling denying
    HES’s motion for new trial, vacate the judgments for plaintiff, and
    remand the case for a new trial consistent with this opinion.

    74
    #15–0574, Haskenhoff v. Homeland Energy Solutions, LLC
    CADY, Chief Justice (concurring in part and dissenting in part).
    I concur in the result reached in the opinion authored by Justice
    Waterman.      I agree the jury verdict must be reversed and a new trial
    must be granted.     I write separately because I do not agree with the
    result or reasoning on all the issues addressed in the opinion by Justice
    Waterman. As to those issues with which I disagree, I join in the opinion
    by Justice Appel.
    I. Direct Negligence Claim.
    The two opinions in this case both hold that a plaintiff may pursue
    a hostile-work-environment claim against an employer under the Iowa
    Civil Rights Act based on supervisor harassment under a legal theory of
    either vicarious liability or negligence. I concur. The two opinions also
    hold an employer cannot assert the affirmative defense recognized for
    vicarious liability claims in Faragher v. City of Boca Raton, 
    524 U.S. 775
    ,
    807–08, 
    118 S. Ct. 2275
    , 2292–93 (1998), and Burlington Industries, Inc.
    v. Ellerth, 
    524 U.S. 742
    , 764–65, 
    118 S. Ct. 2257
    , 2270 (1998), when
    defending a negligence action.     To this, I also concur.     The dispute,
    however, is whether the district court erred in failing to instruct the jury
    that the employee must prove the employer failed to take prompt and
    appropriate remedial action to end the harassment.          I conclude the
    district court erred in failing to integrate this concept into its marshaling
    instruction.
    It is a general rule of law that an employer is liable for negligently
    creating or continuing a hostile work environment.       See Vance v. Ball
    State Univ., 570 U.S ___, ___, 
    133 S. Ct. 2434
    , 2452 (2013). This is a
    correct statement of law, but far too general to be used as a marshaling
    instruction for a claim of employer negligence based on sexual
    75
    harassment by a supervisor.      Negligence in continuing a hostile work
    environment is required to be analyzed within the context of whether or
    not the employer failed to take reasonable remedial action within a
    reasonable period of time.    Boyle v. Alum-Line, Inc., 
    710 N.W.2d 741
    ,
    747–48 (Iowa 2006). This was the essence of Haskenhoff’s claim based
    on supervisor harassment. When the plaintiff asserts a vicarious liability
    claim, the essential analysis is presented as an affirmative defense. See
    Farmland Foods, Inc. v. Dubuque Human Rights Comm’n, 
    672 N.W.2d 733
    , 744 n.2 (Iowa 2003). When the plaintiff asserts a negligence claim,
    the analysis comes within the reasonable care standard of negligence.
    Lynch v. City of Des Moines, 
    454 N.W.2d 827
    , 833 (Iowa 1990).          The
    employee must establish that a reasonable employer knew or should
    have known of the harassment and failed to take reasonable action to
    stop it within a reasonable period of time. Id. The instruction in this
    case totally failed to inform the jury of this essential analysis.    As a
    result, I would conclude the instruction materially misstated the law to
    the detriment of the employer.
    II. Retaliatory Discharge: Causation.
    The two opinions disagree on the proper causation standard for
    retaliatory discharge.   I agree the causation standard under the Iowa
    Civil Rights Act is the same for discrimination claims under Iowa Code
    section 216.6(1)(a) (2011) as it is for retaliation claims under section
    216.11(2).    I also agree the standard is “a motivating factor.”
    Nevertheless, the district court instruction modified this standard to only
    require that the discrimination “played a part.”      This change in the
    standard was not justified.
    In DeBoom v. Raining Rose, Inc., we explained that a motivating
    factor must only have “played a part” and “need not have been the only
    76
    reason.” 
    772 N.W.2d 1
    , 13 (Iowa 2009). Yet, this was only done to aid
    the jury in applying the standard, not to eliminate the central concept of
    the standard that the protected activity be a motivating factor in the
    employer’s decision.   See id.   A motivating factor is one that helped
    compel the decision, and the “played a part” language exists only to
    clarify that the motivating factor need not be the only factor. See id.; see
    also Hasan v. U.S. Dep’t of Labor, 
    400 F.3d 1001
    , 1006 (7th Cir. 2005)
    (“A motivating factor is a factor that weighs in the defendant’s decision to
    take the action complained of—in other words, it is a consideration
    present to his mind that favors, that pushes him toward, the action. It is
    a, not necessarily the, reason that he takes the action. Its precise weight
    in his decision is not important.” (Citations omitted.)).      Therefore, I
    concur in the opinion of Justice Appel to adopt the motivating factor
    causation standard. However, I would find that the jury instruction in
    this case failed to capture this standard.
    III. Retaliatory Discharge: Adverse Employment Action.
    Both opinions agree an adverse employment action is one that
    “well might have ‘dissuaded a reasonable worker from making or
    supporting a charge of discrimination.’ ” Burlington N. & Santa Fe Ry. v.
    White, 
    548 U.S. 53
    , 68, 
    126 S. Ct. 2405
    , 2415 (2006) (quoting Rochon v.
    Gonzales, 
    438 F.3d 1211
    , 1219 (D.C. Cir. 2006)).       Both opinions also
    agree the district court erred in defining an “adverse employment action”
    by including examples of actions that would be adverse as a matter of
    law. I concur on both of these issues. As Burlington Northern instructs,
    and as reason dictates, an adverse action “depend[s] upon the particular
    circumstances.”    548 U.S. at 69, 126 S. Ct. at 2415.        The dispute,
    therefore, is whether the error was harmless. It was not.
    77
    The court instructed the jury that one example of an adverse
    action is a constructive discharge.         A constructive discharge occurs
    “when the employer deliberately makes an employee’s working conditions
    so    intolerable   that   the   employee   is   forced   into   an   involuntary
    resignation.” Van Meter Indus. v. Mason City Human Rights Comm’n, 
    675 N.W.2d 503
    , 511 (Iowa 2004) (quoting First Judicial Dist. Dep’t of Corr.
    Servs. v. Iowa Civil Rights Comm’n, 
    315 N.W.2d 83
    , 87 (Iowa 1982)). We
    recognize constructive discharge to discourage “employers’ ‘end runs’
    around the law”—employers know they cannot retaliate by formally
    terminating the employee, so they may attempt to force the employee to
    quit.    Balmer v. Hawkeye Steel, 
    604 N.W.2d 639
    , 641 (Iowa 2000).
    Whether a discharge is formal or compelled, if it was motivated by the
    employee’s engaging in a protected activity, it is still prohibited
    retaliation.
    But constructive     discharge can also be a separate              claim,
    recognized in extreme cases of hostile work environments. In this type of
    constructive discharge claim, the employee must show the environment
    was so bad he or she had no choice but to quit. See Pa. State Police v.
    Suders, 
    542 U.S. 129
    , 147–48, 
    124 S. Ct. 2342
    , 2354 (2004) (“A hostile-
    environment constructive discharge claim entails something more: A
    plaintiff who advances such a compound claim must show working
    conditions so intolerable that a reasonable person would have felt
    compelled to resign.”).      An employee may want to prove constructive
    discharge in a hostile-work-environment claim “because, as a general
    rule, employees are entitled to back pay only when they have been
    actually or constructively discharged.” Van Meter, 675 N.W.2d at 510–
    11.      In a hostile-environment constructive discharge claim, the
    employer’s motivation for the constructive discharge is irrelevant. See id.
    78
    at 512. In a retaliatory discharge claim, the employee must show the
    employer constructively discharged the employee “because” the employee
    engaged in a protected activity. Iowa Code § 216.11(2). These two uses
    of constructive discharge are related, but distinct.
    Here, the jury was instructed Haskenhoff must show “she was
    subjected to sexual harassment or retaliation[,] which[] made her believe
    there was no chance for fair treatment at Homeland.” (Emphasis added.)
    It is possible the jury was confused by these alternatives. Under these
    instructions, a jury could find the sexual harassment was so severe and
    pervasive that Haskenhoff had no choice but to quit. But, Haskenhoff
    did not advance constructive discharge based on an extreme case of
    hostile work environment.       She used constructive discharge as an
    example of retaliation. Even if the jury appropriately found constructive
    discharge based on the severity of the hostile work environment, it does
    not mean Homeland retaliated against Haskenhoff for reporting the
    harassment. Therefore, the erroneous instruction on adverse action was
    not harmless, and Homeland is entitled to reversal and a new trial.
    IV. Constructive Discharge Instruction.
    Both opinions agree that the district court did not err in the
    constructive discharge instruction by explaining that an employer does
    not need to want the employee to quit.       Both opinions also agree the
    district court erred by using a subjective standard in the constructive
    discharge instruction. I concur on both of these issues. See Van Meter,
    675 N.W.2d at 511–12. The dispute is whether the district court erred in
    refusing to instruct the jury that the employee must give the employer a
    reasonable chance to resolve the problem before it may find the working
    conditions were so intolerable a reasonable employee would have been
    forced into resignation.    I conclude the district court did not err in
    79
    refusing to give this instruction because it would not be a correct
    statement of the law.
    Constructive discharge is a concept of reasonableness. At times, it
    would not be reasonable for an employee to quit without giving the
    employer a chance to resolve the problem. See id. at 511. But, at other
    times, it would not be reasonable to require an employee to remain in
    intolerable working conditions.   See id.    Evidence indicates employees
    often choose not to report discrimination in the workplace at the time it
    occurs. See Brief of Amici Curiae NAACP Legal Defense & Educational
    Fund, Inc. & The National Women’s Law Center in Support of Petitioner,
    Green v. Brennan, 
    578 U.S.
    ___, 
    136 S. Ct. 1769
     (2016) (No. 14–613),
    
    2015 WL 4237675
    , at *14–15 & nn.10–11 (compiling studies).           If the
    unreported discrimination then turns the workplace intolerable, no
    employee should reasonably be expected to remain on the job merely to
    give the employer a chance to fix it.       Consequently, I concur in the
    opinion of Justice Appel that the district court did not err in refusing to
    instruct the jury that an employer must have a reasonable time to fix the
    problem.
    V. Conclusion.
    First, an employee may bring a direct-negligence action against an
    employer based on a supervisor’s harassment. The employer does not
    have the benefit of an affirmative defense when defending such a claim.
    The employee must, however, show the employer knew or should have
    known of the harassment and failed to take reasonable action to stop it
    within a reasonable period of time.      Second, in a claim for retaliatory
    discharge, the employee must show the employee’s engaging in a
    protected activity was a motivating factor in the employer’s decision to
    take an adverse employment action. An adverse-employment action is
    80
    one that would have deterred a reasonable employee from filing a
    complaint.   Actions are not ordinarily adverse as a matter of law, but
    depend on the circumstances. An employer taking such an action need
    not really want the employee to quit, but the employee’s decision to quit
    must be objectively reasonable. A constructive discharge may occur if a
    reasonable employee would find the working conditions intolerable, even
    if that employee did not give the employer an opportunity to correct the
    problem.
    Because the jury instructions in this case did not accurately state
    the above legal principles, I concur in part and with the result of the
    opinion authored by Justice Waterman. I would remand for retrial on
    both counts.   I dissent in part from that opinion and join in part the
    opinion authored by Justice Appel for the reasons expressed above.
    81
    #15–0574, Haskenhoff v. Homeland Energy Solutions, LLC
    APPEL, Justice (concurring in part and dissenting in part).
    I respectfully concur in part and dissent in part from the
    majority/plurality opinion.   In my view, only the instruction related to
    material adverse action in connection with plaintiff’s retaliation claim is
    flawed. I find the district court properly instructed the jury on all other
    issues in this case.
    I. Factual and Procedural Background.
    Homeland Energy Solutions, LLC (HES) is an ethanol processing
    facility in Lawler, Iowa, where it opened in February 2009.           Tina
    Haskenhoff began work at HES as a lab manager immediately upon its
    opening.
    Kevin Howes was Haskenhoff’s supervisor.         Howes, along with
    several of Haskenhoff’s coworkers, repeatedly made demeaning sexual
    comments to Haskenhoff and engaged in other offensive behavior. This
    included Howes frequently commenting on Haskenhoff’s breasts in front
    of Haskenhoff and with other HES employees.
    In November 2010, Haskenhoff informed Howes that she would be
    absent from a meeting for a medical appointment. Howes asked about
    the reason for the appointment and, upon learning that it was for a
    mammogram, told Haskenhoff that she should have the breast exam in
    the parking lot in order to earn some money.
    Later that week, Haskenhoff told Chad Kuhlers about the offensive
    behavior.   Kuhlers was on the board of directors for HES.        Kuhlers
    immediately reported this information to HES’s president and CEO
    Walter Wendland and to human resource manager Sarah Frein.
    Howes learned that Haskenhoff had complained about him, and he
    met with Haskenhoff to ask that she drop the complaint. Howes said
    82
    that he was worried he was going to be fired. Wendland also met with
    Haskenhoff about the complaint, stating the employees of HES were “like
    family.”    Haskenhoff reported later that she found Howes’s and
    Wendland’s behaviors intimidating, and she feared the consequences to
    her employment if she continued with the complaint. Haskenhoff agreed
    to drop the complaint on the assumption that Howes’s behavior would
    change.
    The sexually offensive behavior, however, continued.          Finally, on
    August 8, 2011, Haskenhoff overheard Howes tell another employee that
    Haskenhoff was marrying her fiancé for the money. This comment upset
    Haskenhoff who told a coworker that Howes was “a fucking asshole.”
    Haskenhoff left work in the middle of the day and sent an email to Howes
    complaining about his comment.
    On August 17, Haskenhoff filed a sexual-harassment complaint
    against Howes with Frein.      Several meetings occurred between the
    participants thereafter. Finally, on August 30, Haskenhoff was asked to
    meet with Wendland, David Finke—the CFO and head of human
    resources—and    Howes.       At   this    meeting,    Haskenhoff’s       sexual-
    harassment complaint was discussed.          Additionally, Howes presented
    Haskenhoff with a ninety-day “performance improvement plan” for using
    vulgar language when referring to Howes and walking off the job on
    August     8.   The    plan   noted,      “Failure    to   adhere    to    these
    expectations/conditions will result in further disciplinary action up to
    termination.”
    Haskenhoff later said that after the August 30 meeting, she
    realized HES would take no effective action against Howes and that if she
    continued to complain about the harassment she would be fired.                On
    August 31, Haskenhoff confronted Finke and accused him of letting
    83
    Howes get away with the harassment and permitting Howes to retaliate
    against her. Haskenhoff resigned.
    On May 21, 2012, Haskenhoff brought charges of employment
    discrimination at the Iowa Civil Rights Commission.       The commission
    gave Haskenhoff a release to bring suit, after which she brought suit in
    district court for sexual harassment and retaliation under the Iowa Civil
    Rights Act (ICRA). The jury found in favor of Haskenhoff and awarded
    her damages. HES appealed, and we retained the appeal.
    II. Relationship Between State and Federal Civil Rights
    Statutes.
    A. Introduction. Before analyzing the substantive issues in this
    case, it is important to stress that the ICRA is not simply a knockoff of
    the Federal Civil Rights Act. We have sometimes loosely said that the
    ICRA was “modeled after” or mirrors Title VII. See, e.g., Estate of Harris
    v. Papa John’s Pizza, 
    679 N.W.2d 673
    , 677–78 (Iowa 2004); Pecenka v.
    Fareway Stores, Inc., 
    672 N.W.2d 800
    , 803 (Iowa 2003).               These
    observations have validity only in the most general sense, can be
    materially misleading, and in any case do not provide meaningful
    guidance in the resolution of any concrete controversy under the ICRA.
    First, the modeled-after or mirror theory generally overlooks the
    fact that the ICRA, as well as Title VII, were preceded by more than
    twenty   state   statutes.   See    Andrea   Catania,   State   Employment
    Discrimination Remedies and Pendent Jurisdiction Under Title VII: Access
    to Federal Courts, 32 Am. U. L. Rev. 777, 782 n.24 (1983) [hereinafter
    Catania]. Beginning in the 1940s, states passed civil rights statutes that
    included many of the features now embraced in Title VII. Alex Elson &
    Leonard Schanfield, Local Regulation of Discriminatory Employment
    Practices, 56 Yale L.J. 431, 434 (1947).        There is a rich body of
    84
    commentary on these state laws that seems to have been overlooked in
    our cases suggesting that the ICRA mirrors or is modeled after Title VII. 19
    In fact, both the ICRA and Title VII drew from this preexisting body
    of state law. See Pippen v. State, 
    854 N.W.2d 1
    , 30 (Iowa 2014). In an
    article that appeared in the Iowa Law Review in the year that the ICRA
    was passed, Professor Arthur Bonfield, a leading proponent of the
    legislation, cited the experience in other states in support of the
    legislation.     Arthur Earl Bonfield, State Civil Rights Statutes: Some
    Proposals, 
    49 Iowa L
    . Rev. 1067, 1082 & n.65 (1964).
    Thus, the ICRA and Title VII both mirrored and were modeled after
    preexisting state law in the same general sense that the ICRA is modeled
    after or mirrors federal law.          For example, the “because of” causation
    language in the ICRA and Title VII, which is at the heart of one of the
    issues in this litigation, was used in state civil rights statutes that
    predate them. 20 Similarly, retaliation provisions in state civil rights laws
    19See,  e.g., Arthur E. Bonfield, The Substance of American Fair Employment
    Practices Legislation I: Employers, 61 Nw. U. L. Rev. 907, 909–10 & n.6 (1967); Elmer A.
    Carter, Practical Considerations of Anti-Discrimination Legislation—Experience Under the
    New York Law Against Discrimination, 40 Cornell L.Q. 40, 40 (1954); Richard B. Dyson
    & Elizabeth D. Dyson, Commission Enforcement of State Laws Against Discrimination: A
    Comparative Analysis of the Kansas Act, 14 U. Kan. L. Rev. 29, 29–31 (1965); Herbert
    Hill, Twenty Years of State Fair Employment Practice Commissions: A Critical Analysis
    with Recommendations, 14 Buff. L. Rev. 22, 22 (1964); Robert G. Meiners, Fair
    Employment Practices Legislation, 62 Dick. L. Rev. 31, 31 & n.1, 33 (1957); Arnold H.
    Sutin, The Experience of State Fair Employment Commissions: A Comparative Study, 18
    Vand. L. Rev. 965, 965 & n.1 (1965).
    20The because-of causation language in Title VII’s discrimination and retaliation
    provisions is also found in earlier state antidiscrimination statutes. See, e.g., Wash.
    Rev. Code § 49.60.030 (1957) (“The right to be free from discrimination because of race,
    creed, color, or national origin is recognized as and declared to be a civil right.”); Int’l
    Bhd. of Elec. Workers Local 35 v. Comm’n on Civil Rights, 
    102 A.2d 366
    , 367 n.1 (Conn.
    1953) (quoting the 1949 Connecticut Fair Employment Practices Act that “[i]t shall be
    an unfair employment practice . . . (c) for a labor organization, because of the race,
    color, religious creed, national origin or ancestry of any individual to exclude from full
    membership rights or to expel from its membership such individual or to discriminate
    in any way against any of its members”).
    85
    predated the retaliation provision in the ICRA and Title VII. See, e.g.,
    Wash. Rev. Code § 49.60.200 (1957); Wis. Stat. § 111.32(5)(b)(3) (1961);
    Morroe Berger, New York State Law Against Discrimination: Operation
    and Administration, 35 Cornell L. Rev. 747, 751 (1950) (describing the
    contents of New York’s 1945 law). In this case, the relevant provisions of
    the ICRA and Title VII are, as a matter of historical fact, modeled after or
    mirror preexisting state law. Alex Long, State Anti-Discrimination Law as
    Model for Amending the Americans with Disabilities Act, 65 U. Pitt. L. Rev.
    597, 600 (2004) (stating “Congress modeled Title VII . . . on existing state
    anti-discrimination laws”).
    Second, the modeled-after or mirrors theory particularly overlooks
    the fact that Iowa had a preexisting civil rights statute before Title VII
    was enacted.   Iowa’s first civil rights act was enacted in 1883 shortly
    after the United States Supreme Court, in an appalling decision
    corrected only decades later, held that a key portion of the Federal Civil
    Rights Act of 1871—prohibiting discrimination by private persons—was
    unconstitutional. See United States v. Harris, 
    106 U.S. 629
    , 644, 
    1 S. Ct. 601
    , 613 (1883), abrogated by Griffin v. Breckenridge, 
    403 U.S. 88
    , 104,
    
    91 S. Ct. 1790
    , 1799 (1971).     Then, in 1963, fully a year prior to the
    enactment of Title VII, Iowa joined twenty-six states in enacting a statute
    prohibiting discrimination in employment.        That statute declared it
    unlawful “for any person or employer to discriminate in the employment
    of individuals because of race, religion, color, national origin, or
    ancestry.” 1963 Iowa Acts ch. 330, § 1 (codified at Iowa Code § 105A.7
    (1966)). Thus, the because-of causation language that later appeared in
    the ICRA was based on language in an Iowa statute that predated Title
    VII which was modeled after civil rights legislation in other states. It is
    simply wrong to suggest that the because-of language in the ICRA was
    86
    modeled after Title VII.       A more accurate statement would be that the
    because-of language in Title VII was modeled after state law precedents,
    including the ICRA of 1963.
    Third, while the texts of the two statutes are sometimes similar,
    they are often quite dissimilar. There are material differences between
    the two statutes in scope, structure, and remedy. Thus, a generalized
    statement that the ICRA is modeled on, similar to, or mirrors Title VII
    even from a textual viewpoint is often not true. 21               Further, as will be
    shown below, the legislative history behind Title VII is often quite
    distinctive and plainly inapplicable to any construction of the ICRA.
    Instead of employing a generalized and often inaccurate slogan, in
    interpreting the ICRA we must engage in serious, provision-by-provision
    analysis, recognizing similarities when they appear, but also honoring
    the differences.
    B. Legislative Direction that the ICRA “Shall Be Construed
    Broadly to Meet Its Purposes.”              As all judges, lawyers, and litigants
    know, the ICRA has many ambiguities and gaps which courts are called
    upon to resolve and fill in the context of adversarial litigation. While the
    Iowa legislature has advanced a statute with ambiguities and gaps, it has
    provided courts with an instruction on how to approach it. Specifically,
    the legislature has directed that the ICRA “shall be construed broadly to
    21The  same historical mistake is often made with respect to the Iowa
    Constitution, which some claim is modeled after the United States Constitution. In
    fact, the United States Constitution, and every provision of its Bill of Rights, was
    derived from provisions of state constitutions that existed before 1789, especially the
    Virginia Declaration of Rights and the Massachusetts Constitution. The documents
    published in Paris by Benjamin Franklin, hailed to be the first written constitutions,
    were state constitutions, not the later and largely derivative United States Constitution.
    See Daniel J. Hulsebosch, The Revolutionary Portfolio: Constitution-Making and the
    Wider World in the American Revolution, 47 Suffolk U. L. Rev. 759, 802 & n.222 (2014).
    87
    effectuate its purposes.” Iowa Code § 216.18(1) (2011). As we pointed
    out in Pippen, there is no comparable language in the federal statute.
    854 N.W.2d at 28.        Iowa Code section 216.18(1) is an example of a
    provision of the ICRA that is not modeled after and does not mirror Title
    VII.
    Our better reasoned cases show that this marked textual difference
    is consequential. In Pippen, we pointed out that a number of other state
    supreme courts have construed similar statutory language in civil rights
    acts to require the “widest constitutional application.” Id. (quoting Fair
    Emp’t Practices Comm’n v. Rush-Presbyterian-St. Luke’s Med. Ctr., 
    354 N.E.2d 596
    , 600 (Ill. App. Ct. 1976) (holding that a wide application was
    required given the legislative intent for the remedial provisions of the
    act)); see also Wondzell v. Alaska Wood Prods., Inc., 
    601 P.2d 584
    , 585
    (Alaska 1979) (finding Alaska civil rights act not simply modeled after
    federal law, but “intended to be more broadly interpreted than federal law
    to further the goal of eradication of discrimination . . . [as shown by the]
    legislature’s intent ‘to put as many “teeth” into the statute as possible’ ”
    (quoting McLean v. State, 
    583 P.2d 867
    , 869 (Alaska 1978) (citations
    omitted))); Marquis v. City of Spokane, 
    922 P.2d 43
    , 49–50 (Wash. 1996)
    (en    banc)   (explicitly   recognizing    legislative   directive   to   construe
    Washington civil rights statute liberally); Allison v. Hous. Auth. of Seattle,
    
    821 P.2d 34
    , 38 (Wash. 1981) (en banc) (“Title VII differs from
    [Washington civil rights law] in that Title VII does not contain a provision
    which requires liberal construction for the accomplishment of its
    purposes.”); Lodis v. Corbis Holdings, Inc., 
    292 P.3d 779
    , 787 (Wash. Ct.
    App. 2013) (Adopting federal precedent would “impermissibly narrow the
    protective language and purposes of [Washington’s civil rights law],
    contrary to the liberal construction mandate of the act.”).
    88
    A few state civil rights statutes passed prior to the ICRA also
    contained provisions directing courts to construe the statute broadly.
    See, e.g., Del. Code Ann. tit. 6, § 4502 (1963) (“This chapter shall be
    liberally construed to the end that the rights herein provided for all
    people without regard to race, creed, color or national origin may be
    effectively safeguarded.”); Wash. Rev. Code § 49.60.020 (1957) (“The
    provisions   of   this   chapter   shall   be   construed   liberally   for   the
    accomplishment of the purposes thereof.”); W. Va. Code § 5-11-265(161)
    (1961) (“The provisions of this article shall be liberally construed to
    accomplish its objectives and purposes.”); Wis. Stat. § 111.31 (1961) (“All
    the provisions of this subchapter shall be liberally construed for the
    accomplishment of this purpose.”).
    Plainly, a narrow construction of the ICRA would be in defiance of
    the legislative mandate to broadly construe the statute to effectuate its
    purposes and would amount to a judicial recrafting of the statute. As we
    stated in Pippen, an Iowa court “must keep in mind the legislative
    direction of broadly interpreting the Act when choosing among plausible
    legal alternatives.” 854 N.W.2d at 28.
    The legislative direction that we broadly interpret the ICRA makes
    federal authority that chooses narrow constructions among available
    options suspect.     Federal courts, and particularly the United States
    Supreme Court, have demonstrated a marked tendency to embrace a
    narrow construction of federal civil rights statutes in the face of more
    generous plausible alternatives.      As a result, Congress has repeatedly
    overridden by statute narrow interpretations of federal civil rights laws.

    overridden by Congress include General Electric Co. v. Gilbert,

    90
    5 (codified as amended at 42 U.S.C. § 2000e–5(e)(3)). See, e.g., Sandra F.
    Sperino,      Diminishing      Deference:       Learning     Lessons      from   Recent
    Congressional      Rejection    of   the    Supreme        Court’s   Interpretation   of
    Discrimination Statutes, 33 Rutgers L. Rec. 40, 40 (2009) (stating “blind
    adherence to federal interpretation of discrimination principles on state
    employment discrimination claims is not only often inappropriate, but
    also   has     seriously     impacted       the    development       of    employment
    discrimination law”); Sandra F. Sperino, Revitalizing State Employment
    Discrimination Law, 20 Geo. Mason L. Rev. 545, 583 (2013) [hereinafter
    Sperino, Revitalizing] (“[T]he federal courts have repeatedly interpreted
    federal law narrowly in ways that drew a response from Congress.”).
    Uncritical incorporation of the principles of these now superseded cases
    under the ICRA would run counter to the Iowa legislature’s directive that
    the ICRA be “broadly interpreted to effectuate its purposes.” Iowa Code
    § 216.18(1); see also Goodpaster v. Schwan’s Home Servs., Inc., 
    849 N.W.2d 1
    , 9–10 (Iowa 2014).
    And these are only the cases that Congress managed to override.
    Whenever a highly divided United States Supreme Court chooses a
    narrow interpretive path under federal civil rights statutes, we must
    consider whether the dissenting opinion is more consistent with the
    legislative direction that the ICRA be broadly interpreted to achieve its
    goals. 22
    22It is sometimes asserted that we should follow federal precedent under Title VII
    to foster uniformity. When Congress enacted Title VII in 1964, approximately one-half
    of the states had some kind of antidiscrimination statute. See Susan Elizabeth Powley,
    Exploring a Second Level of Parity: Suggestions for Developing an Analytical Framework
    for Forum Selection in Employment Discrimination Litigation, 44 Vand. L. Rev. 641, 667 &
    n.184 (1991). Congress expressly considered the question of requiring uniformity when
    it declared that Title VII does not preempt state law. See 42 U.S.C. § 2000h-4;
    Alexander v. Gardner-Denver Co., 
    415 U.S. 36
    , 48–49, 
    94 S. Ct. 1011
    , 1019–20 (1974)
    (“[T]he legislative history of Title VII manifests a congressional intent to allow an
    91
    The directive to construe the ICRA broadly has had impact. For
    instance, in Goodpaster, we considered whether an intermittent or
    episodic impairment—multiple sclerosis—fell within the definition of
    “disability” under the ICRA. 849 N.W.2d at 6. We emphasized section
    216.8(1)’s instruction to interpret the ICRA broadly in reaching the result
    that multiple sclerosis could be a disability under the ICRA. Id. at 9–10,
    18. We noted that this difference with federal law rendered many federal
    cases inapposite in interpreting the ICRA. Id. at 10. We cited several of
    our cases in which section 216.18(1) had a “substantive impact on the
    outcome.”      Id.; see, e.g., Polk Cty. Secondary Rds. v. Iowa Civil Rights
    Comm’n, 
    468 N.W.2d 811
    , 815–16 (Iowa 1991).
    In construing a provision of the ICRA, the legislative direction to
    broadly construe the statute to effectuate its purposes must be
    recognized. To ignore this provision is to rewrite the statute to achieve
    desired policy results.
    C. Textual Differences Between the ICRA and Federal Civil
    Rights Statutes. When there are textual differences between the ICRA
    and federal civil rights statutes, we must be attentive to those
    differences.    When there are textual differences, the modeled-after or
    mirror declarations have no application, and indeed an opposite
    _________________________
    individual to pursue independently his rights under both Title VII and other applicable
    state and federal statutes. The clear inference is that Title VII was designed to
    supplement rather than supplant, existing laws and institutions relating to employment
    discrimination.”)   Further, it is doubtful that uniformity will be advanced by
    incorporation of federal law. The United States Supreme Court has resolved only a
    handful of cases in the civil rights area over the years. The literature is full of
    documentation of various splits in the federal circuits on numerous questions that the
    Supreme Court has not resolved. The stability of incorporating a handful of Supreme
    Court precedents is outweighed by dragging into Iowa law the many controversies in the
    federal caselaw that have not been resolved.
    92
    conclusion may be more appropriate, namely, that differences in text are
    deliberate and substantive.
    A good example of the need to recognize textual differences
    between the ICRA and federal civil rights law is Hulme v. Barrett
    (Hulme I), 
    449 N.W.2d 629
     (1990). In Hulme I, we considered whether
    the provision of the Federal Age Discrimination in Employment Act
    (ADEA) of 1967 limiting coverage to those forty years of age or older
    applied under the ICRA.       Id. at 631.   The district court, apparently
    following a version of the modeled-after or mirror theory, held that the
    limitation in the Federal ADEA also applied under the ICRA. Id. at 631.
    We reversed. Id. at 632. We noted that while the federal statute
    had language explicitly limiting claims to persons above the age of forty,
    the ICRA had no such textual limitation. Id. at 631–32. In Hulme I, we
    correctly declined to follow federal precedent because the text of our
    statute was not modeled after and did not mirror federal law. As will be
    seen below, there are important textual and legislative history differences
    between the ICRA and Title VII as it relates to the causation element in
    retaliation claims.
    D. Structural Differences Between the ICRA and Federal Civil
    Rights Statutes. As pointed out in Pippen, there is also an important
    structural difference between the ICRA and various civil rights statutes.
    See 854 N.W.2d at 28. The ICRA is a unified statute. In contrast, the
    federal civil rights regime is more fragmented. See Age Discrimination in
    Employment Act of 1967, 29 U.S.C. § 623; Civil Rights Act of 1964, 42
    U.S.C. § 2000e–2 (Title VII); American with Disabilities Act of 1990, 42
    U.S.C. § 12112. Thus, while the federal courts have developed different
    tests for different causes of action under different statutes, the Iowa
    statute generally calls out for a singular, unified approach.    See, e.g.,
    93
    Gross v. FBL Fin. Servs., Inc., 
    557 U.S. 167
    , 176–78, 
    129 S. Ct. 2343
    ,
    2350–51 (2009) (holding that Title VII and ADEA causation standards are
    different).   It would be very difficult to come to the same conclusion
    under the ICRA, a unified statute with one statutory provision
    establishing what constitutes status-based discrimination. The fractured
    nature of federal law compared to the unified approach of the ICRA
    makes wholesale importation of federal law questionable. See Sperino,
    Revitalizing, 20 Geo. Mason L. Rev. at 560 (contrasting unified state
    regimes with fractured federal law).
    E. Interpretation of Gaps and Ambiguous Phrases. Civil rights
    statutes contain many notoriously open-ended or ambiguous phrases
    that cry out for interpretation. For ambiguous phrases, there is rarely
    only one plausible interpretation.     See Hack v. President & Fellows of
    Yale Coll., 
    237 F.3d 81
    , 95 (2d Cir. 2000) (“The Act’s ambiguous language
    . . . has allowed a number of contradictory standards to emerge.”). For
    example, the phrase “because of” sex, race, and other classifications has
    given rise to a wide number of potential interpretations. See David S.
    Schwartz, When Is Sex Because of Sex? The Causation Problem in Sexual
    Harassment Law, 150 U. Pa. L. Rev. 1697, 1708–09 (2002) [hereinafter
    Schwartz] (noting different approaches to ambiguous terms).      There is
    simply no requirement that in construing ambiguous phrases we should
    follow the lead of the United States Supreme Court rather than that of
    another state court or where our own judgment would lead us.
    Further, many legal structures developed by the United States
    Supreme Court are not found in the statutory text of Title VII and have
    been fashioned by the Supreme Court based on its policy perceptions.
    For example, the requirement that harassment be “pervasive and severe”
    in order to amount to actionable discrimination does not appear in the
    94
    text of Title VII. See Meritor Sav. Bank, FSB v. Vinson, 
    477 U.S. 57
    , 67,
    
    106 S. Ct. 2399
    , 2405–06 (1986). It is a judicial construct created by the
    United States Supreme Court.     The complex architecture surrounding
    disparate impact also has no clear textual foundation. Cf. Wards Cove,
    490 U.S. at 656–58, 109 S. Ct. at 2124–25; Watson v. Ft. Worth Bank &
    Tr., 
    487 U.S. 977
    , 986–89, 
    108 S. Ct. 2777
    , 2784–86 (1988); Griggs v.
    Duke Power Co., 
    401 U.S. 424
    , 431–32, 
    91 S. Ct. 849
    , 853–54 (1970).
    The burden-shifting approach to causation found in various United
    States Supreme Court cases is without explicit textual support.       See
    Desert Palace, Inc. v. Costa, 
    539 U.S. 90
    , 93–94, 
    123 S. Ct. 2148
    , 2150–
    51 (2003); Price Waterhouse, 490 U.S. at 244–45, 109 S. Ct. at 1787–88;
    McDonnell Douglas Corp. v. Green, 
    411 U.S. 792
    , 802, 
    93 S. Ct. 1817
    ,
    1824 (1973). The notion that an “adverse action” is required to support a
    retaliation claim is not mentioned in Title VII. Burlington N. & Santa Fe
    Ry. v. White, 
    548 U.S. 53
    , 56–57, 
    126 S. Ct. 2405
    , 2408–09 (2006). And,
    the Faragher–Ellerth defense developed by the Supreme Court for cases
    involving vicarious liability of supervisors when there is no tangible
    adverse employment action has no explicit textual support in Title VII,
    but was crafted primarily as a result of the policy considerations of the
    Court. See Faragher v. City of Boca Raton, 
    524 U.S. 775
    , 804–05, 
    118 S. Ct. 2275
    , 2291–92 (1998); Burlington Indus., Inc. v. Ellerth, 
    524 U.S. 742
    , 765, 
    118 S. Ct. 2257
    , 2270 (1998).
    These judicially developed constructs are not textually guided, but
    instead reflect the views of a majority of the United States Supreme
    Court on the subject of discrimination. If one believes, for example, that
    discrimination in the workplace is a relatively rare occurrence, the
    development of demanding judicial standards through interpretation or
    construction may seem to make sense.         On the other hand, if one
    95
    believes that discrimination is widespread and intractable, a different
    result might occur. Sperino, Revitalizing, 20 Geo. Mason L. Rev. at 575–
    77.
    Because of the lack of textual support, it is not surprising that a
    number of courts have declined to create a Faragher–Ellerth defense for
    cases involving vicarious liability under state civil rights acts. See, e.g.,
    Myrick v. GTE Main St. Inc., 
    73 F. Supp. 2d 94
    , 98 (D. Mass. 1999)
    (declining to apply Faragher–Ellerth defense on state law grounds);
    Chambers v. Trettco, Inc., 
    614 N.W.2d 910
    , 918 (Mich. 1990) (rejecting
    Faragher–Ellerth      under    Michigan        law);   Pollock   v.   Wetterau    Food
    Distribution Grp., 
    11 S.W.3d 754
    , 767 (Mo. Ct. App. 1999) (refusing to
    add words to Missouri human rights statute to establish a Faragher–
    Ellerth defense).
    In making choices regarding ambiguous phrases and determining
    whether and how to fill legislative gaps, Iowa courts are free to depart
    from what are often very narrow and cramped approaches of federal
    law. 23 For example, in Goodpaster, we rejected United States Supreme
    Court precedent that, contrary to the ICRA, declared the Americans with
    Disabilities Act must be “interpreted strictly to create a demanding
    standard for qualifying as disabled.” 849 N.W.2d at 10 (quoting Toyota,
    534 U.S. at 197, 122 S. Ct. at 691); see Sutton, 527 U.S. at 488, 119
    S. Ct. at 2149. The Supreme Court’s determination to strictly interpret
    23No one would suggest, for instance, that if Iowa were to adopt a statute
    modeled after the statute of another state, we would be compelled to follow the
    interpretations of the supreme court of the other state in interpretation of Iowa law.
    See Crosby v. Alton Ochsner Med. Found., 
    276 So. 2d 661
    , 665 (Miss. 1973) (holding
    that when Mississippi adopted a statute modeled after a Georgia enactment, decisions
    of the Georgia courts did not bind Mississippi courts in interpretation of the statute).
    96
    the statute flies in the face of the Iowa legislature’s direction to construe
    the statute broadly. See Iowa Code § 216.18(1). 24
    Thus, in order to choose the best interpretive option on a statutory
    issue under the ICRA, it is not enough to simply cut and paste a version
    of federal law into the Northwest Reporter and call it a day. 25 We do not
    follow federal constitutional interpretations lockstep, even of parallel
    provisions,     and     there    is   no    reason     to   follow    federal     statutory
    interpretation in a lockstep fashion in similar statutes. 26                       Instead,
    24For  an interesting discussion, see Tyler S. Smith, Note, A Mid-Life Crisis in the
    Interpretation of the Iowa Civil Rights Act of 1965: How Should State Courts Interpret
    Original State Antidiscrimination Statutes After Federal Counterpart Statutes Are
    Amended?, 64 Drake L. Rev. 1117, 1141–49 (2016).
    25Such a reaction has been referred to as a “Pavlovian response” to federal
    opinions. Stone v. St. Joseph’s Hosp. of Parkersburg, 
    538 S.E.2d 389
    , 410 (W. Va. 2000)
    (McGraw, J., concurring in part and dissenting in part).
    26Many   state civil rights cases have declined to follow federal authorities. See,

    with the thrust of our state’s statute” (quoting Wentz v. Industrial Automation, 847
    97
    consistent with preservation principles, 27 we must first identify potential
    interpretive options that are available to the court.                  Ordinarily, this
    involves a survey of state as well as federal law.                Once the potential
    alternative approaches are identified, we should proceed to select the
    interpretive option that we find most consistent with the ICRA, its
    underlying purposes, and the legislative direction that the text be
    “broadly construed to effectuate its purposes.” Iowa Code § 216.18(1).
    We may, of course, rely on persuasive federal precedents, especially
    when the language of Title VII and the ICRA are, in fact, similar, the
    federal interpretation is consistent with the legislature’s directive of
    broad interpretation, and the rationale of the federal caselaw persuades
    us that the best choice has been made. But we must look for persuasive
    reasoning that fits the Iowa statute. And, we should not mask our policy

    choices in resolving ambiguities and filling statutory gaps through
    language suggesting that the choice was somehow inexorable or
    determined with a mathematical certainty that may be found in the
    scientific world but evades the law. We are in the business of judging,
    not calculating.
    F. Independent       Interpretation       of   ICRA   Consistent    with
    Federalism and Congressional Intent Behind Title VII.                    When
    Congress enacted Title VII, approximately one-half of the states had civil
    rights statutes already.       Catania, 32 Am. U. L. Rev. at 782 n.24.
    Congress expressly determined not to preempt state law.              42 U.S.C.
    § 2000h-4.    As noted by the United States Supreme Court, Congress
    intended Title VII “to supplement, rather than supplant, existing laws
    and institutions related to employment discrimination.” See Alexander v.
    Gardner-Denver Co., 
    415 U.S. 36
    , 47–48, 
    94 S. Ct. 1011
    , 1019–20 (1974)
    (finding legislative history showed clear congressional intent to allow an
    individual to pursue state law remedies simultaneously with Title VII).
    Congress plainly did not intend to preempt state civil rights laws. Id. As
    noted by Professor Bonfield, “the federal act . . . recognizes the continued
    effectiveness of state fair employment laws and provides that they will
    retain a vital and perhaps dominant role in this area.”              Arthur E.
    Bonfield,    The   Substance    of   American    Fair   Employment    Practices
    Legislation I: Employers, 61 Nw. U. L. Rev. 907, 919 (1967).
    A conclusion that state courts should generally follow the twists
    and turns in federal law would be ironic in light of the congressional
    intent to allow, if not encourage, state experimentation.
    G. A Note on Law of the Case, Stare Decisis, and Dictum. If
    one looks through our ICRA cases, federal cases are often simply cited
    for propositions of law without substantive discussion. Often times in
    99
    this setting, we were simply restating legal principles that the parties
    were not contesting in the case. When a legal principle is embraced by
    the parties by agreement and is not contested on appeal, the court’s
    subsequent recitation of the legal principle is not a holding in the case
    that was a product of an adversary proceeding. See Berger v. Gen. United
    Grp., Inc., 
    268 N.W.2d 630
    , 635 (Iowa 1978) (holding that because
    plaintiffs assumed Delaware law was properly pled and proven by
    defendants, we would consider Delaware law, but stressed that this case
    was not precedent for ignoring our rules of pleading and proof on foreign
    law); see also United States v. Hemingway, 
    734 F.3d 323
    , 335 (4th Cir.
    2013) (finding a prior case to have no precedential value on a question
    because the issue was not contested in the earlier case); Goldberger v.
    Integrated Res., Inc., 
    209 F.3d 43
    , 49 (2d Cir. 2000) (earlier case was not
    precedent because “that issue was neither contested by the parties, nor
    addressed by the panel”); Fulton Found. v. Wis. Dep’t of Taxation, 
    108 N.W.2d 312
    , 316–17 (Wis. 1961) (holding previous case when no one
    challenged the issue could not be precedent on the issue); Silver Lake
    Sanitary Dist. v. Wis. Dep’t of Nat. Res., 
    607 N.W.2d 50
    , 54 (Wis. Ct. App.
    1999) (“It is blackletter law that an opinion does not establish binding
    precedent for an issue if that issue was neither contested nor decided.”).
    An uncontested statement of law is not entitled to stare decisis.
    See, e.g., Hemingway, 734 F.3d at 335; Goldberg, 209 F.3d at 49; Berger,
    268 N.W.2d at 635; Fulton, 109 N.W.2d at 317. Instead, the agreed upon
    legal principle is law of the case binding on the parties in the event of
    retrial, but nothing more. State v. Ragland, 
    812 N.W.2d 654
    , 658 (Iowa
    2012) (holding settled legal principles are binding on litigants throughout
    future progress of case); accord State ex rel. Goettsch v. Diacite Distribs.,

    596 N.W.2d 532
    , 537 (Iowa 1999).

    III. Negligence Theory, Vicarious Liability, and the Faragher–
    Ellerth Defense.
    A. Overview of the Issue.           When an employee is sexually
    harassed by other employees, the question arises to what extent the
    employer may be held responsible for the actions of its employees under
    civil rights laws.   One question is whether it should matter that the
    harassment was committed by a coworker or by a supervisor.             If the
    harassment is by a supervisor, should the supervisor be considered an
    agent of the employer and thus provide a basis for vicarious liability? If
    different legal consequences flow from harassment involving a supervisor
    compared to harassment by coworkers, how does the law handle
    situations when harassers include both coworkers and supervisors?
    As with many similar issues, nothing in the ICRA or Title VII
    expressly answers these questions, and as a result, courts are left to
    resolve the issue through statutory interpretation. Courts are required
    to fill the gaps in the statute in the crucible of an adversary proceeding.
    B. Challenged Trial Court Instruction. The starting place of our
    analysis is a review of the jury instructions on Haskenhoff’s claim of
    negligence under the ICRA.       In Instruction No. 14, the marshalling
    instruction for sexual harassment, the jury was instructed Haskenhoff
    had to prove, among other things, that “6. Homeland Energy Solutions,
    L.L.C., knew or should have known of the occurrence of one or more
    sexually harassing incidents.     7. Homeland Energy Solutions, L.L.C.,
    acted negligently in creating or continuing a hostile work environment.”
    The language in Instruction No. 14 is drawn nearly verbatim from the
    United States Supreme Court description of direct negligence claims
    under Title VII provided in Vance v. Ball State University, 
    570 U.S.
    ___,
    ___, 
    133 S. Ct. 2434
    , 2452 (2013), which stated “an employer will always
    101
    be liable when its negligence leads to the creation or continuation of a
    hostile work environment.”
    With respect to negligence, Instruction No. 17 instructed the jury
    that
    “Negligence” means failure to use ordinary care.
    Ordinary care is the care which a reasonably careful
    employer would use in similar circumstances. “Negligence”
    is doing something a reasonable careful employer would not
    do under similar circumstances, or failing to do something a
    reasonably careful; employer would do under similar
    circumstances.
    Except for substituting the term “employer” for “person,” Instruction
    No. 17 is a verbatim version of Iowa State Bar Association Jury
    Instruction 700.2 entitled “Ordinary Care—Common Law Negligence—
    Defined.” This instruction has been used countless times in the courts
    of this state in negligence cases.
    Finally, in Instruction No. 24, the jury was instructed that
    [o]nce an employer knows or should have known of sexual
    harassment, it must take prompt remedial action reasonably
    calculated to end the conduct. The employer has a duty to
    take this remedial action even if an employee asks the
    employer not to do anything.
    (Emphasis added.)     Instruction No. 24 is derived from the affirmative
    defense for vicarious liability claims from Faragher–Ellerth.
    C. Overview of Review of Jury Instructions. In fashioning jury
    instructions, we have repeatedly stated that a trial court “need not
    instruct in a particular way so long as the subject of the applicable law is
    correctly covered when all the instructions are read together.” State v.
    Uthe, 
    542 N.W.2d 810
    , 815 (Iowa 1996). A trial court “is free to draft jury
    instructions in its own language.” Hoekstra v. Farm Bureau Mut. Ins.,
    
    382 N.W.2d 100
    , 110 (Iowa 1986). We have emphasized that the court
    need not use terms suggested by the parties. Bossuyt v. Osage Farmers
    102
    Nat’l Bank, 
    360 N.W.2d 769
    , 772 (Iowa 1985). And, our instructions do
    not need to follow particular authorities. In Bossuyt, we emphasized that
    an instruction on fraud was sufficient even though it did not follow the
    exact phrasing of the Restatement (Second) of Contracts. Id. at 774.
    Our well-established Iowa caselaw is consistent with federal
    precedent.   As noted by one federal appellate court, review of jury
    instructions does not require “word-by-word hairsplitting.”     Johnson v.
    Breeden, 
    280 F.3d 1308
    , 1314 (11th Cir. 2002). As long as instructions
    “accurately reflect the law, the trial judge is given wide discretion as to
    the style and wording employed.” United States v. Starke, 
    62 F.3d 1374
    ,
    1380 (11th Cir. 1995).
    The question in considering the legal sufficiency of a jury
    instruction is whether relevant elements of a claim “may be adequately
    conveyed to the jury by the evidence and by argument of counsel under
    the instruction that the court gave.” Hillrichs v. Avco Corp., 
    478 N.W.2d 70
    , 74 (Iowa 1991), abrogated on other grounds by Reed v. Chrysler Corp.,
    
    494 N.W.2d 224
    , 226 (Iowa 1992).          What is important is that the
    instructions, considered as a whole, were sufficient “so that the jurors
    understood the issues and were not misled.” Johnson, 280 F.3d at 1314
    (quoting Starke, 62 F.3d at 1380). Generally understood terms which are
    in ordinary usage do not need to be defined. State v. Kellogg, 
    542 N.W.2d 514
    , 516 (Iowa 1996).
    When error in a jury instruction is not of constitutional magnitude,
    “the test of prejudice is whether it sufficiently appears that the rights of
    the complaining party have been injuriously affected or that the party
    has suffered a miscarriage of justice.” State v. Gansz, 
    376 N.W.2d 887
    ,
    891 (Iowa 1985). Reversal is required if the jury instructions misled the
    103
    jury or if the court materially misstates the law.   Rivera v. Woodward
    Res. Ctr., 
    865 N.W.2d 887
    , 892 (Iowa 2015).
    D. Positions of the Parties.
    1. Defendants. HES maintains the district court erred in its jury
    instructions by “adopting a common law negligence standard” and
    denying HES’s affirmative defense. Specifically, HES asserts that under
    the ICRA, HES was entitled to an instruction on the Faragher–Ellerth
    affirmative defense, which has been adopted by the United States
    Supreme Court. HES maintains that it is entitled to the Faragher–Ellerth
    defense in this case because the plaintiff’s claims involve a supervisor
    and the alleged harassment did not culminate in a tangible employment
    action.   Under Faragher–Ellerth, HES asserts entitlement to an
    affirmative defense that allows it to show “(a) [HES] exercised reasonable
    care to prevent and correct promptly any sexually harassing behavior,
    and (b) that [Haskenhoff] unreasonably failed to take advantage of any
    preventative or corrective opportunities provided by [HES] or to avoid
    harm otherwise.” See Ellerth, 524 U.S. at 765, 118 S. Ct. at 2270.
    HES recognizes that in cases involving coworker harassment, a
    different framework applies. HES recognized that in Vance, the Supreme
    Court declared, “If the harassing employee is the victim’s co-worker, the
    employer is liable only if it was negligent in controlling working
    conditions.” 
    570 U.S.
    at ___, 133 S. Ct. at 2439.
    But HES claims that a plaintiff in a negligence case involving
    coworkers must prove more than the Vance formulation that the
    employer is liable only if it was negligent in controlling working
    conditions.   Id.   HES adds another element to the negligence claim.
    According to HES, in cases involving coworker harassment, the plaintiff
    is required to prove not only the presence of harassment that the
    104
    employer knew or should have known existed, but also that the employer
    “failed to take prompt and appropriate corrective action.” McCombs v.
    Meijer, Inc., 
    395 F.3d 346
    , 353 (6th Cir. 2005). An instruction that the
    plaintiff must prove the defendant acted negligently in creating or
    continuing a sexually hostile environment is not enough according to
    HES.     It claims that the district court was obligated to include its
    additional verbal formulation. HES further asserts prejudice arose from
    the failure to so instruct. Rivera, 365 N.W.2d at 892.
    2. Haskenhoff. Haskenhoff argues that under the ICRA, a plaintiff
    may choose to proceed under either a direct negligence or vicarious
    liability theory.   She asserts that she elected to proceed under a
    negligence theory, and thus the law related to vicarious liability claims
    against an employer is irrelevant.
    Haskenhoff supports her choice-of-theories approach by citing
    language of the Supreme Court in Vance, 
    570 U.S.
    at ___, 133 S. Ct. at
    2434. In Vance, the United States Supreme Court stated “an employer
    will always be liable when its negligence leads to the creation or
    continuation of a hostile work environment.” Id. at ___, 133 S. Ct. at 2452
    (emphasis added).     Haskenhoff further cites Vance for the proposition
    that a situation where some harassers are coworkers and others are
    supervisors “presents no problem for the negligence standard.”       Id. at
    ___, 133 S. Ct. at 2451–52; see also Phelan v. Cook County, 
    463 F.3d 773
    , 784 (7th Cir. 2006) (declining to sort out who were supervisors
    since    sexual   harassment   claim   survived   summary   judgment    via
    negligence method); Sharp v. Houston, 
    164 F.3d 923
    , 928–29 (5th Cir.
    1999) (allowing jury instruction on negligence theory even though
    harasser was top manager in plaintiff’s unit).
    105
    Because at trial Haskenhoff proceeded only on a direct negligence
    theory, she claims that HES was not entitled to the Faragher–Ellerth
    defense, which may be utilized only in a vicarious liability case.      See
    Johnson v. Shinseki, 
    811 F. Supp. 2d 336
    , 348 n.2 (D.C. Cir. 2011);
    Curry v. District of Columbia, 
    195 F.3d 654
    , 660 (D.C. Cir. 1999).
    According to Haskenhoff, the reason for the Faragher–Ellerth defense was
    to ensure that employers would not be held automatically liable for
    harassment involving supervisors. Faragher, 524 U.S. at 804, 118 S. Ct.
    at 2291; Ellerth 524 U.S. at 763, 118 S. Ct. at 2270. But when vicarious
    liability is not asserted, the Faragher–Ellerth framework is inapplicable.
    Direct negligence, according to Haskenhoff, is a tried and true method of
    litigating sexual-harassment cases.       See Boyle v. Alum-Line, Inc., 
    710 N.W.2d 741
    , 748 (Iowa 2006); Farmland Foods, Inc. v. Dubuque Human
    Rights Comm’n, 
    672 N.W.2d 733
    , 744 (Iowa 2003).
    In addition, Haskenhoff maintains that HES was not prejudiced by
    the failure to give HES’s requested Faragher–Ellerth defense instruction.
    Haskenhoff argues the plaintiff’s burden under a negligence standard is
    higher than that under Faragher–Ellerth.             In a negligence case,
    Haskenhoff asserts, the plaintiff must prove the employer was negligent.
    In a vicarious liability case, however, the plaintiff does not have to prove
    negligence, and the defense has the burden of showing “prompt and
    effective” remedial action under Faragher–Ellerth.
    E. The Distinction Between Direct Negligence Claims and
    Vicarious Liability Claims Under Federal and Civil Rights State Law.
    1. Distinction between direct negligence and derivative liability.
    The federal and state civil rights caselaw clearly distinguishes direct
    negligence claims from claims based on vicarious liability.        A direct
    negligence approach is generally used in federal cases under Title VII by
    106
    plaintiffs who seek to thrust liability onto employers for the harassment
    they suffered at the hands of coworkers.        The direct negligence cases
    stress that employer liability for coworkers “is direct liability for
    negligently allowing harassment, not vicarious liability for the harassing
    actions of employees.” Williamson v. Houston, 
    148 F.3d 462
    , 465 (5th
    Cir. 1998); Pierce v. Commonwealth Life Ins., 
    40 F.3d 796
    , 804 n.11 (6th
    Cir. 1994) (“The term ‘respondeat superior’—which connotes derivative
    liability—is an incorrect label for co-worker harassment cases, where the
    employer is directly liable for its own negligence.”).
    2. Two types of direct negligence: negligence in the creation and
    negligence in the continuation of harassment.            The Supreme Court
    explored some elements of a direct negligence claim in Vance, 
    570 U.S.
    at
    ___, 133 S. Ct. at 2434. Vance held a plaintiff could bring a derivative
    claim based on vicarious liability for acts of a supervisor if the plaintiff
    suffers tangible adverse consequences of the harassment, but that
    vicarious liability could not arise if the consequences were intangible. Id.
    at ___, 133 S. Ct. at 2439. In Vance, the Supreme Court recognized the
    two theories of direct negligence actions, observing that “an employer will
    always be liable when its negligence leads to the creation or continuation
    of a hostile work environment.” Id. at ___, 133 S. Ct. at 2452 (emphasis
    added).
    3. Relevant evidence in fact-based direct negligence actions.      In
    discussing direct negligence actions as a distinct alternative to a
    derivative claim based on vicarious liability, the Vance Court observed,
    “Evidence that an employer did not monitor the workplace, failed to
    respond to complaints, failed to provide a system for registering
    complaints, or effectively discouraged complaints from being filed would
    be relevant.”   Id. at ___, 133 S. Ct. at 2453 (emphasis added).      These
    107
    evidentiary observations appear to be germane to direct negligence
    actions based on a failure to prevent and negligence related to the
    continuation of harassment.
    4. Combining coworkers and supervisors in direct negligence
    actions. While a direct negligence theory is generally used to affix liability
    to the employer when the harassers are solely coworkers, the question
    arises as to whether a direct negligence claim can also be made when one
    or even all of the harassers are supervisors. A plaintiff may want to use
    such a strategy when it is not entirely clear whether the harassers would
    be considered coworkers or supervisors.        By assuming the burden of
    proving direct negligence, rather than shifting the burden to the
    defendant under the derivative approach of vicarious liability, the
    plaintiff avoids the risk that the court could ultimately conclude a
    harasser was not a supervisor and thus an employer could not be held
    derivatively liable on a vicarious liability theory. Thus, plaintiffs are not
    forced to litigate harassment cases involving supervisors under a
    vicarious liability theory. They may choose to proceed under the more
    demanding direct negligence theory.
    There is dicta in support of the notion that supervisors may be
    considered coworkers for purposes of a direct negligence claim brought
    under Title VII.   In Ellerth, the Supreme Court observed that while a
    derivative claim based upon a vicarious liability might be available for
    claims against supervisors under certain circumstances, “an employer
    can be liable, nonetheless, where its own negligence is a cause of the
    harassment.” 524 U.S. at 758–59, 118 S. Ct. at 2267. There is lower
    federal and state court authority consistent with the proposition that the
    conduct of supervisors may be considered part of a direct negligence
    claim brought by a Title VII plaintiff. See, e.g., Rios Da Silva v. One, Inc.,
    108
    
    980 F. Supp. 2d 148
    , 163 (D.P.R. 2013); Nadeau v. Rainbow Rugs, Inc.,
    
    675 A.2d 973
    , 976–77 (Me. 1996); Hoy v. Angelone, 
    691 A.2d 476
    , 481
    (Pa. Super. Ct. 1997).
    F. The      Kaleidoscope        of   Federal     Circuit     Model       Jury
    Instructions on Direct Negligence in Harassment Cases. A survey of
    federal circuit court model jury instructions for harassment claims based
    on   direct   negligence   demonstrates         the   kaleidoscope       of   verbal
    formulations that may be used in instructing juries on direct negligence
    claims. See generally 3C Kevin F. O’Malley et al., Federal Jury Practice
    and Instructions § 171:23, at 262–77 (6th ed. 2014) [hereinafter O’Malley
    2014] (providing model jury instructions from the federal circuits and
    collecting cases on those instructions). Some instructions are long, some
    are short. In describing the plaintiff’s burden in showing the employer
    was negligent, some use language of reasonableness, some use the
    somewhat narrower language of prompt and appropriate or effective
    remedial action, and many use both.
    The model instruction for the United States Court of Appeals for
    the Third Circuit is detailed and elaborate.           According to the Third
    Circuit   model   instruction,   in    sexual    harassment      cases    involving
    nonsupervisors, the plaintiff must show that management “knew, or
    should have known of the abusive conduct.” Id. at 264. If the plaintiff
    proves its case, however, the defendant is allowed an affirmative defense.
    Id. at 265.
    Interestingly, though, the affirmative defense, which the defendant
    has the burden of proving, is couched in terms of reasonableness. See
    id. According to the Third Circuit model instruction, in order to satisfy
    the requirements of the affirmative defense, the defendant must show
    (1) that it “exercised reasonable care” to prevent the harassment and to
    109
    promptly correct any harassing behavior, and (2) that the plaintiff
    “unreasonably failed to take advantage of any preventive or corrective
    opportunities.”       Id.    On the first prong of reasonableness, the Third
    Circuit offers a further instruction that a defendant meets that burden
    by showing the defendant had an explicit policy against harassment, the
    policy was fully communicated to its employees, the policy provided a
    reasonable way for plaintiff to make a claim of harassment, and
    reasonable steps were taken to correct the problem.            Id.   The Third
    Circuit instruction for coworker harassment tends to mix and match
    concepts of direct negligence liability with concepts of derivative liability
    based on vicarious liability theory as outlined in Faragher–Ellerth. See
    id. at 264–65.
    The Fifth Circuit takes a materially different tack in a lengthy
    model instruction on direct negligent-harassment claims by coworkers.
    3C Kevin F. O’Malley et al., Federal Jury Practice and Instructions
    § 171:23 (6th ed.), Westlaw (database updated Aug. 2016).            Under the
    Fifth Circuit instruction for a claim of a hostile work environment
    involving coworkers based on direct negligence, the plaintiff must show
    the defendant “knew, or in the exercise of reasonable care should have
    known, that [the plaintiff] was being [sexually harassed] because of the
    [Plaintiff’s sex].”    Id.   The Fifth Circuit instruction states the plaintiff
    must show that the harassment was “known by or communicated to a
    person who had authority to receive, address, or report the complaint,”
    or that the harassment was so “open and obvious” the defendant should
    have known of it. Id. In addition, the plaintiff must prove the defendant
    failed to take “prompt remedial action” to stop the harassment.             Id.
    Interestingly, though, the instruction further defines “prompt remedial
    110
    action” as conduct “reasonably calculated to stop the harassment and
    remedy the situation.” Id.
    The Seventh Circuit model jury instruction eschews the arguably
    meandering instruction of the Fifth Circuit for a more direct approach.
    O’Malley 2014, at 270–71. In a harassment case involving negligence, a
    jury in the Seventh Circuit is instructed that when harassment has been
    proved, an employer is liable if it “knew or should have known about the
    conduct”   and   “did   not   take   reasonable   steps   to   [correct   the
    situation]/[prevent harassment from recurring].” Id. at 271. That is it.
    The Seventh Circuit model instruction is quite similar to the marshalling
    instruction given by the district court in this case and, compared to the
    Fifth Circuit model instruction, has the advantage of simplicity.
    The Eighth Circuit model instruction requires that the plaintiff
    show the defendant “knew or should have known” of the alleged conduct
    and “the defendant failed to take prompt and appropriate corrective
    action.” Id. at 272. Although this instruction differs somewhat from the
    instruction in our case, “prompt and appropriate corrective action” does
    not seem to be a lesser standard than “reasonableness.” An action that
    is not “prompt” might still be considered reasonable by a jury, while an
    action that is “appropriate” is surely also reasonable.
    The Ninth Circuit has a longer model instruction for direct
    negligence claims, but it comes to essentially the same place as the
    Seventh Circuit’s instruction. Id. at 274–75. Under the Ninth Circuit’s
    instruction, a plaintiff who proves harassment and seeks to impose
    liability on the employer must show that “the defendant or a member of
    the defendant’s management knew or should have known of the
    harassment and failed to take prompt, effective remedial action
    reasonably calculated to end the harassment.”       Id. at 274. The Ninth
    111
    Circuit instruction further defines who qualifies as management and
    states the defendant’s remedial action “must be reasonable and
    adequate.” Id. Although more detailed, there is no substantive difference
    between the Ninth Circuit instruction and the totality of the district
    court’s instruction in this case.
    What these diverse jury instructions demonstrate is that there is
    not one “correct” jury instruction in a direct negligence case. They can
    vary from the fairly complex instructions used by the Fifth and Ninth
    Circuits to the very simple instruction utilized by the Seventh Circuit. It
    is clear, however, that the model instructions in the Fifth, Seventh,
    Eighth, and Ninth Circuits are consistent with the trial court’s
    instruction in this case.
    G. Iowa Caselaw on Negligence Claims.          In the pre-Faragher–
    Ellerth cases of Chauffeurs, Teamsters & Helpers, Local Union No. 238 v.
    Iowa Civil Rights Commission, 
    394 N.W.2d 375
     (Iowa 1986), and Lynch v.
    Des Moines, 
    454 N.W.2d 827
     (Iowa 1990), we considered cases in which
    the plaintiff claimed the defendants maintained hostile environments
    based on race and sex respectively. In describing one of the elements of
    a hostile-environment claim, we stated in Lynch that the plaintiff must
    prove “the employer knew or should have known of the harassment and
    failed to take prompt and appropriate remedial action.” 454 N.W.2d at
    833 (emphasis added). In Chauffeurs, we used a slightly different verbal
    formulation, indicating that the plaintiff needs to prove the defendant
    knew or should have known of the harassment and “failed to take prompt
    remedial action.” 394 N.W.2d at 378 (emphasis added). The cases do not
    discuss a difference between “prompt remedial action” or “prompt and
    appropriate remedial action.”       In both cases, we held the evidence
    sufficient to support the plaintiff’s claims.
    112
    In another pre-Faragher–Ellerth case, Vaughn v. Ag Processing, Inc.,
    we again were asked to consider a hostile-environment harassment
    claim, this time based on religion. 
    459 N.W.2d 627
    , 632 (Iowa 1990).
    We noted specifically the plaintiff did not assert that “Mueller, as
    supervisor, was acting as Ag or that Ag was strictly liable for Mueller’s
    actions.”   Id. at 634.   In other words, plaintiff was pursuing a direct
    negligence theory and not an agency theory that would give rise to strict
    liability against the employer.
    Unlike in Chauffeurs and Lynch, however, we found in Vaughn that
    the defendant was entitled to prevail. Id. at 639. We found that while
    the defendant knew of the harassment, the employer took prompt
    remedial action to remedy the problem.        Id. at 634.   We explained
    “prompt remedial action” as placing “a reasonable duty on an employer
    who is aware of discrimination in the workplace to take reasonable steps
    to remedy it.” Id. at 634 (emphasis added). We noted that whether an
    employer takes such reasonable steps to remedy the harassment is a
    question of fact.   Id.   We further noted in Vaughn that the employer’s
    conduct was “especially reasonable” in light of the evidence which
    showed that the employer did not know the plaintiff was a victim of
    religious discrimination.    Id. at 635.   Under Vaughn, it seems that
    “prompt remedial action” and “reasonableness” are interchangeable
    concepts, much like the model instructions in the Fifth and Ninth
    Circuits.
    Our first post-Faragher–Ellerth case involving a claim of a hostile
    environment was Farmland Foods, 
    672 N.W.2d 733
    . In Farmland Foods,
    we cited Eighth Circuit precedent for the proposition that in order to
    establish a hostile-environment claim, a plaintiff must show the
    employer “knew or should have known of the harassment and failed to
    113
    take proper remedial action.” Id. at 744. We then added, as dictum, a
    sentence stating, “When a supervisor perpetrates the harassment, but no
    tangible employment action occurred, the employer may assert the
    Faragher–Ellerth affirmative defense to avoid liability.” 28 Id. In Farmland
    Foods, we concluded the plaintiff failed, on the evidence presented, to
    show a hostile environment of racial harassment.                  Id. at 746.      As a
    result, the question of whether the employer acted reasonably in
    response to the allegedly hostile environment was not considered.
    In Boyle, 710 N.W.2d at 741, we considered whether a plaintiff
    established a hostile environment based on sex.                   The district court
    concluded the employer knew of the harassment but the employer “did
    take steps reasonably calculated to stop the sexual harassment.” Id. at
    747 (emphasis added). We also stated that in order to establish liability
    for a hostile environment, a plaintiff must show that “the employer knew
    or should have known of the harassment and failed to take proper
    remedial action.” Id. at 746 (emphasis added) (quoting Farmland Foods,
    672 N.W.2d at 744).            We equated the test, however, with “steps
    reasonably calculated to end the sexual harassment.”                       Id. at 747
    (emphasis added). After canvassing the record, we concluded the record
    did not support the trial court’s conclusion that the employer took steps
    reasonably calculated to stop the harassment. Id. Because the employer
    did not show that it took steps “reasonably calculated to stop the sexual
    28This  dictum is correct as applied to a derivative claim based upon vicarious
    liability, but it does not apply to a claim based upon direct negligence. When a
    supervisor participates in the harassment, the plaintiff has a choice. The plaintiff may
    proceed directly against the employer under a negligence theory and bear the burden of
    showing that the employer knew or should have known of the harassment and failed to
    stop it, or she may proceed under a vicarious liability theory. If the plaintiff proceeds
    under a vicarious liability theory, then the employer is entitled to the Faragher–Ellerth
    defense.
    114
    harassment,” we stated that the employer failed to “implement prompt
    and appropriate corrective action.” Id. at 748. In Boyle as in Vaughn,
    the shorthand phrases “prompt remedial action” and “prompt and
    appropriate action” are equated with steps “reasonably calculated to stop
    the sexual harassment.” See id.; Vaughn, 459 N.W.2d at 634.
    H. Discussion: Can the Faragher–Ellerth Defense “Jump the
    Track”? 29      At the outset, there is no question under the current
    prevailing state and federal caselaw that a plaintiff in a sexual-
    harassment case may proceed against an employer on a direct negligence
    theory and that the direct negligence theory is distinct from a derivative
    claim based on vicarious liability.          I would thus set aside the caselaw
    that might relate to derivative claims based on vicarious liability and
    focus solely on the law related to direct negligence.
    In direct negligence cases, an employer is entitled to a jury
    instruction stating that the plaintiff has the burden of proving the
    employer’s negligence “leads to the creation or the continuation of a
    hostile work environment.”           Vance, 
    570 U.S.
    ___, 133 S. Ct. at 2452.
    Under negligence theory, there is no Faragher–Ellerth affirmative defense.
    The Faragher–Ellerth affirmative defense, if it is available, applies only in
    cases based on vicarious liability. Beckford v. Dep’t of Corr., 
    605 F.3d 951
    , 960–61 (11th Cir. 2010) (finding a refusal to give a Faragher defense
    instruction proper when plaintiff did not argue vicarious liability). 30
    29See generally Alex B. Long, “If the Train Should Jump the Track . . .”: Divergent
    Interpretations of State and Federal Employment Discrimination Statutes, 
    40 Ga. L
    . Rev.
    469 (2006).
    30Although   the parties have assumed in our cases that the Faragher–Ellerth
    defense is available under the ICRA, we have not adjudicated the issue in a contested
    case. A number of state courts have declined to adopt the Faragher–Ellerth defense
    under their state civil rights acts. See, e.g., Myrick, 73 F. Supp. 2d at 98; Chambers,
    614 N.W.2d at 918; Pollock, 11 S.W.3d at 767.
    115
    As a result, it is important to note that under a claim based on
    negligence, the second prong of the Faragher–Ellerth defense, namely,
    that the employer may prove the plaintiff failed to avail herself of an
    employer’s internal remedy, has no application. Indeed, that is the main
    advantage of a negligence claim—specifically, that it can provide a basis
    for liability when the harassment victim never formally complained to his
    or her employer. See Zayadeen v. Abbott Molecular, Inc., No. 10 C 4621,
    
    2013 WL 361726

    1153, 1161–62 (2013).     The fact that a report to management is not
    required is an important feature of direct negligence liability, for many
    women are reluctant to step forward to report sexual harassment to
    superiors.   See L. Camile Hebert, Why Don’t “Reasonable Women”
    Complain About Sexual Harassment?, 82 Ind. L.J. 711, 724–29 (2007).
    For instance, some victims may not report harassment for fear of
    retaliation from coworkers. See Christopher M. Courts, Note, An Adverse
    Employment Action—Not Just an Unfriendly Place to Work: Co-Worker
    Retaliatory Harassment Under Title VII, 
    87 Iowa L
    . Rev. 235, 236 (2001).
    As a result, HES’s argument that it was entitled to an affirmative
    Faragher–Ellerth defense is without merit.     Interestingly, however, the
    trial court did instruct the jury on the first prong of the Faragher–Ellerth
    affirmative defense in Instruction No. 24. That instruction stated that
    HES had the burden of showing that it took prompt and appropriate
    remedial action reasonably calculated to end the conduct.             In a
    negligence action, however, HES does not have any burden. Rather, the
    burden is always on the plaintiff to prove negligence. But HES sought
    this instruction and does not object to it now. It may have been wrong,
    116
    but HES cannot complain about an instruction it sought and does not
    challenge on appeal.
    I now turn to the question of whether the district court properly
    instructed the jury on what the plaintiff must show to affix liability to
    HES based upon direct negligence. The marshalling instruction required
    the plaintiff to prove that HES acted “negligently in the creation or
    continuance of a hostile work environment.” These words are virtually
    lifted verbatim from Vance and are a correct statement of law.
    So far so good. Next, the district court offered an instruction on
    negligence.   The district court instructed the jury that “negligence”
    means “the failure to exercise ordinary care.” Further, “ordinary care is
    the care which a reasonably careful employer would use under all the
    circumstances.”
    HES asserts the district court’s formulation is inadequate.        It
    insists the district court was required to instruct the jury that the
    plaintiff must show not that the employer failed to act reasonably, but
    instead that the employer failed to use “prompt and appropriate remedial
    action.”
    In short, HES insists on magic words. But not only does our law
    not require magic words for jury instructions, but such demanding word
    regimes are contrary to our declarations that the trial court “need not
    instruct in a particular way so long as the subject of the applicable law is
    correctly covered.” Uthe, 542 N.W.2d at 815; Hoekstra, 382 N.W.2d at
    110.
    One can only wonder what the difference is between acting
    reasonably and acting appropriately.        Federal cases refer to such
    arguments with disdain as “word-by-word hairsplitting.”       See Johnson,
    280 F.3d at 1314.      Certainly, the difference between the concept of
    117
    reasonability   in   the   district   court’s   negligence   instruction   and
    appropriateness in HES’s formulation is not a basis for reversal here.
    HES’s formulation also uses the term “prompt” while the district
    court’s instruction simply referred to reasonability. This is not the stuff
    of reversible error. Our caselaw has repeatedly equated prompt remedial
    action with action “reasonably calculated to stop the sexual harassment”
    or placing a “reasonable duty on an employer who is aware of
    discrimination in the workplace to take reasonable steps to remedy it.”
    Boyle, 710 N.W.2d at 747; Vaughn, 459 N.W.2d at 634. If anything, the
    term “prompt” may be more demanding on the employer then the
    reasonability requirement as instructed by the district court.         In any
    event, I would find that no reasonable jury would draw a distinction
    between reasonable action by an employer to stop the harassment and
    prompt and appropriate remedial action.
    In considering the negligence instructions given in this case, the
    instructions accurately reflect the law. The instructions were very close
    to the model instruction in use in the Seventh Circuit and, in their
    totality, are certainly consistent with the model instructions in the Fifth
    and Ninth Circuits.        The district court instructed the jury in the
    marshalling instruction that Haskenhoff had the burden to prove that
    HES “knew or should have known” of the harassment. The instruction
    further required Haskenhoff to prove that HES “acted negligently in
    creating or continuing a hostile work environment.” The district court
    also gave a proper instruction to the jury regarding the meaning of
    negligence as a failure to use ordinary care “which a reasonably careful
    employer would use in a similar circumstance.”
    The fact the instruction was adequate is demonstrated by the
    record in this case. In her opening statement, Haskenhoff told the jury
    118
    that “an employer has a duty to . . . protect its employees insofar as they
    can reasonably do so from sexual harassment.” Further, Haskenhoff told
    the jury “if an employer knows about sexual harassment and lets it
    continue for a month—let alone several months—and it violates the law
    . . . the employer must compensate the victim for whatever harm is
    caused.”
    In its opening statement, HES responded that “this is a case about
    a lab manager that failed for months or years to report prohibited
    conduct and, before HES could act on the information she reported, quit
    on the job.” HES further asked the jury “will the evidence show that the
    plaintiff followed HES policy . . . and that HES was given a chance to
    promptly remedy the conduct that she did report?”         Then in closing
    argument, Haskenhoff told the jury,
    Homeland acted negligently . . . . They did not monitor the
    workplace. They did nothing more to protect Tina going
    forward . . . . They did nothing to stop it. They allowed the
    environment to continue and caused great harm to Tina . . . .
    Once the employer knows or should have known about
    sexual harassment, it must take prompt remedial action
    reasonably calculated to end the conduct.
    (Emphasis added.) Thus, in the closing statement, Haskenhoff’s counsel
    told the jury that the obligation of the employer, once it knew or should
    have known about the harassment, was to take “prompt remedial action
    reasonably calculated to end the conduct.”
    In its closing statement, HES picked up on the plaintiff’s closing
    argument.    HES told the jury that “she needs to prove . . . that HES
    failed to act reasonably and responsibly in a way calculated to bring the
    conduct of which she complained to an end.             That’s the biggest
    question.”
    Further, HES told the jury that
    119
    Instruction 17 and 24 go to the last element, if you will.
    What the plaintiff has to prove is that this employer was
    either not doing something a reasonable careful employer
    would do or failed to do something a reasonably careful
    employer would do.
    HES further asked the jury “did the company put a plan together that
    was reasonably calculated to end the conduct?” According to HES, the
    company “wanted it to just stop,” and cited “the evidence here that it
    did.” In rebuttal, Haskenhoff told the jury, “You have to conduct prompt,
    thorough     and    impartial    investigation   into   any   potential   sexual
    harassment, however you become aware of it, whether it is in a written
    complaint or not, whether you see or whether it’s just a rumor.”
    What the opening and closing arguments demonstrate is that the
    instructions, though brief like the Seventh Circuit model instruction,
    were clearly and demonstrably sufficient to allow HES to make the
    argument which it claims on appeal it was foreclosed from making. See
    Hillrichs, 478 N.W.2d at 74 (finding instructions adequate in which they
    allowed consideration of evidence and arguments by counsel on legal
    elements).   HES thus advances a battle not over principle, but over
    semantics.       Under the instructions, Haskenhoff had the burden of
    proving negligence.       As the model instructions of the various circuits
    indicate, “prompt and effective remedial action” is a another way of
    expressing reasonableness. See also Lehmann v. Toys ‘R’ Us, Inc., 
    626 A.2d 445
    , 464 (N.J. 1993) (“Effective” remedial measures are those
    “reasonably calculated to end the harassment.”); Campbell v. Fla. Steel
    Corp., 
    919 S.W.2d 26
    , 33 (Tenn. 1996) (stating no precise definition of
    “prompt and appropriate remedial action” though in general employers
    are   required     to   take   steps   “reasonably   calculated”   to   terminate
    harassment); Davis v. Modine Mfg., Co., 
    979 S.W.2d 602
    , 607 (Tenn. Ct.
    App. 1998) (equating “prompt and appropriate corrective action” with
    120
    action “reasonably calculated to terminate the alleged harassment”). If
    HES could convince a jury that it took prompt and effective remedial
    action, it would not be found to have acted unreasonably. There is no
    error in the instructions that were based on the language of Vance and
    the ISBA Model Jury Instruction defining negligence.
    IV. Causation Instruction on Retaliatory Discharge.
    A. Introduction.
    1. Ambiguity in “because” language.          Causation has been one of
    the most controversial aspects of employment law.             The literature is
    chock-full     of   alternate   causation    standards,   including   “but   for,”
    “motivating factor,” “substantial factor,” “a motivating factor,” and similar
    terms.   There are arguments aplenty for each of them.           See generally
    Kendall D. Isaac, Is It “A” Or Is It “The”? Deciphering the Motivating-Factor
    Standard in Employment Discrimination and Retaliation Cases, 1 Tex.
    A&M L. Rev. 55, 73–77 (2013); Schwartz, 150 U. Pa. L. Rev. at 1708
    (citing various different approaches to causation requirement).
    By using “because” in Iowa Code section 216.11(2), the section
    related to causation in retaliation cases, the Iowa legislature has left the
    causation question to the courts to determine as a matter of statutory
    construction. Because the statute is ambiguous, we have a number of
    plausible interpretive choices.      In exercising our authority to construe
    the statute and choose among plausible interpretive choices, we must be
    cognizant of the text of the statute, its goals, and the legislative direction
    to construe the ICRA broadly to effectuate its underlying purposes. Id.
    § 216.18(1).
    2. Centrality of reporting requirements in Iowa civil rights law and
    linkage to substantive violations. Some may regard a retaliation claim as
    a second-class claim under the ICRA compared to status-based
    121
    discrimination claims. Retaliation claims, however, are not second-class
    claims at all, but instead are claims that strike at the very heart of the
    enforcement regime of the ICRA. Under the ICRA, a claimant is required
    to file a timely claim with the Iowa Civil Rights Commission in order to
    present a claim.    McElroy v. State, 
    703 N.W.2d 385
    , 391 (Iowa 2005).
    The requirement is mandatory. See id. Thus, being able to file a claim
    free from fear of workplace retaliation is directly linked to the ability of a
    claimant to vindicate his or her rights under the ICRA. A statute that
    forces workers to invoke an administrative process or to cooperate in
    subsequent investigations should protect workers who comply. Sandra
    F. Sperino, Retaliation and the Reasonable Person, 
    67 Fla. L
    . Rev. 2031,
    2074 (2015) [hereinafter Sperino, Retaliation].
    As a result, keeping the channels of reporting potential civil rights
    claims free, open, and unfettered is crucial to vindicating the substantive
    policies of the ICRA.    And, closing the channels of reporting through
    retaliation does not only affect the party but harms the system itself. See
    Richard Moberly, The Supreme Court’s Antiretaliation Principle, 61 Case
    W. Res. L. Rev. 375, 380 (2010) (citing law enforcement rationale). In
    addition to protecting the person claiming discrimination, coworkers
    participating in investigations need protection if the system is to function
    properly. A retaliation claim thus is not a satellite claim on the fringes of
    civil rights law. It is an essential claim, without which the ICRA could
    not fulfill its laudatory statutory purpose.
    3. Purpose of retaliation provision as affecting causation.          In
    considering whether the plaintiff has presented sufficient evidence to
    reach a jury on a retaliation claim, much debate has occurred on the
    level of causation—a motivating factor, a substantial factor, a but-for
    factor, etc.   Aside from level of causation, however, there is another
    122
    issue. Causation is not a free radical floating around the employment
    law universe untethered to any other legal principle. There is a relational
    question, namely, causal connection in relation to what, exactly?
    And that is a key question. In the retaliation context, the question
    is whether the causation is judged by whether the alleged retaliatory
    conduct would likely deter a plaintiff from making a complaint
    contemplated by our civil rights laws.      Or, is it judged by whether it
    “affects a term, condition, or privilege” of employment? This relational
    question is just as important as the calibration of the “level” of causation
    required in determining whether a plaintiff has made a sufficient showing
    to support a retaliation claim.
    4. Difficulty of fact-finding in retaliation cases. Finally, we should
    recognize the evidentiary challenges facing a plaintiff in proving a
    retaliation claim.   In retaliation cases, we are necessarily probing into
    difficult factual issues involving the motivation of the defendant.     The
    evidence related to motivation is almost always in the hands of the
    defendant. In addition, the evidence in the modern work place is often
    indirect, although “smoking guns” are still occasionally uncovered.
    Further, to the extent causation involves whether a reasonable
    person in the position of the plaintiff would be deterred from utilizing
    appropriate   reporting   procedures,     the   question   becomes    highly
    contextual.   Highly contextual factual issues are rarely amenable to
    summary judgment.
    B. Challenged Trial Court Instructions.         With respect to her
    retaliation claim, the jury was instructed that Haskenhoff need only
    prove that her report of sexual harassment “played a part” in HES’s
    decision to take adverse employment action against her to prevail on her
    retaliation claim. The jury was further instructed that to “play a part”
    123
    the report need only have been “a factor” in HES’s employment action
    but “need not be the only factor.”
    HES offered an instruction that Haskenhoff’s report of sexual
    harassment must have been “a significant factor motivating the
    Defendant’s decision to take materially adverse employment action
    against Plaintiff” in order for the jury to find in favor of Haskenhoff on
    her retaliation claim.
    C. Federal Caselaw on Causation Standard for Civil Rights
    Claims.
    1. Causation standard for status-based discrimination. Title VII of
    the Civil Rights Act of 1964 provides that it “is an unlawful employment
    practice for an employer . . . to discriminate against any individual . . .
    because of such individual’s race, color, religion, sex, or national origin.”
    42 U.S.C. § 2000e-2(a)(1)–(2) (emphasis added).           Like prior state
    legislatures who used the term in their state civil rights acts, Congress
    provided no guidance as to the meaning of the ambiguous phrase
    “because of” in its status-based discrimination provision. The meaning
    of the phrase “because of” has been a major point of controversy in
    federal civil rights law.
    Early federal caselaw struggling with the “because of” language
    came to mixed results. Many federal courts adopted a relaxed standard
    of proof close to a played-a-part standard. See King v. N.H. Dep’t of Res.
    & Econ. Dev., 
    420 F. Supp. 1317
    , 1327 (D. N.H. 1976). Others adopted
    something like a significant-factor test. See Baldwin v. Birmingham Bd.
    of Educ., 
    648 F.2d 950
    , 956 (5th Cir. 1981); Whiting v. Jackson State
    Univ., 
    616 F.2d 116
    , 121 (5th Cir. 1980). Some cases embraced a more
    124
    stringent determinative-factor or motivating-factor test. See Womack v.
    Munson, 
    619 F.2d 1292
    , 1297 (8th Cir. 1980). 31
    In Price Waterhouse, the United States Supreme Court considered
    the   meaning      of   the   term    “because     of”   under     the   status-based
    classification provision of Title VII.       490 U.S. at 239–40, 109 S. Ct. at
    1785.    A majority of the court concluded the proper approach to the
    phrase “because of” was a motivating-factor test. Id. at 258, 109 S. Ct.
    at 1795 (plurality opinion); id. at 259, 109 S. Ct. at 1795 (White, J.,
    concurring); id. at 276, 109 S. Ct. at 1804 (O’Connor, J., concurring). As
    Justice Brennan noted in his plurality opinion, Congress has specifically
    rejected an amendment to put the term “solely” in front of the “because
    of” language.       Id. at 241, 109 S. Ct. at 1785 (plurality opinion).
    According     to   Justice     Brennan,      Congress      intended      to   eliminate
    employment decisions in which discriminatory motivation “played a part”
    in an employment decision, even if it was not the sole basis for the
    decision. Id.
    The Price Waterhouse Court, however, added an important caveat
    to its motivating-factor interpretation. In cases of mixed motive, the Price
    Waterhouse Court concluded that an employer was entitled to a “same
    decision” affirmative defense. Id. at 242, 109 S. Ct. at 1786. In other
    words, if an employer could show in a mixed-motive case that the same
    decision would have been made absent the discriminatory motivation,
    the employer could escape liability. Id.
    In response to the same-decision aspect of Price Waterhouse and
    other Supreme Court civil rights decisions, Congress enacted the Civil
    31Womack   appears to have been subsequently modified by later cases. See, e.g.,
    Tuttle v. Henry J. Kaiser Co., 
    921 F.2d 183
    , 186 n.3 (8th Cir. 1990); Balicao v. Univ. of
    Minn., 
    737 F.2d 747
    , 750 n.2 (8th Cir. 1984).
    125
    Rights Act of 1991. Civil Rights Act of 1991, Pub. L. No. 102-166, 105
    Stat. 1071 (codified at 42 U.S.C. § 2000e-2(m)). The purpose of the 1991
    Act, according to Congress, was to provide “additional protections against
    unlawful discrimination in employment.”            Id.   The Civil Rights Act of
    1991    added    the   following   section    to   Title   VII:   “[A]n   unlawful
    unemployment practice is established when the complaining party
    demonstrates that race, color, religion, sex, or national origin was a
    motivating factor for any employment practice, even though other factors
    also motivated the practice.” 42 U.S.C. § 2000e-2(m) (emphasis added).
    This section plainly endorsed the motivating-factor approach of Price
    Waterhouse.
    Congress further amended the statute, however, to limit the same-
    decision affirmative defense established in Price Waterhouse. Congress
    limited the same-decision defense by providing that if the employer
    demonstrates that it
    would have taken the same action in the absence of the
    impermissible motivating factor, the court . . . may grant
    declaratory relief, injunctive relief . . . and [limited] attorney’s
    fees and costs . . . and . . . shall not award damages or issue
    an order requiring any admission, reinstatement, hiring,
    promotion, or payment.
    42 U.S.C. § 2000e-5(g)(2)(B).      The impact of this amendment provided
    employees with greater protection than allowed under the Supreme
    Court’s decision in Price Waterhouse.         The same-decision amendment
    was thus consistent with the underlying statutory purpose of the Civil
    Rights Act of 1991 to “provide additional protections” to employees
    suffering from impermissible discrimination.
    Notably, however, the Civil Rights Act of 1991 did not amend the
    retaliation provision of Title VII, which also contains a because-of
    requirement of causation. What gloss should be put on the because-of
    126
    language in the retaliation in light of the Price Waterhouse and the Civil
    Rights Act of 1991?
    There were a number of possible approaches.          Several courts
    concluded that because Congress did not specifically amend the separate
    retaliation section in the Civil Rights Act of 1991, the causation standard
    existing before the passage of the Act announced in Price Waterhouse
    provided the proper approach to causation in retaliation claims.      See,
    e.g., Medlock v. Ortho Biotech, Inc., 
    164 F.3d 545
    , 552 n.4 (10th Cir.
    1999); Woodson v. Scott Paper Co., 
    109 F.3d 913
    , 934–35 (3d Cir. 1997);
    Tanca v. Nordberg, 
    98 F.3d 680
    , 683–84 (lst Cir. 1996).              While
    recognizing that the Civil Rights Act of 1991 amendments did not extend
    to retaliation claims, these courts took the position that the Supreme
    Court’s decision in Price Waterhouse, which involved a status-based
    claim, did extend to retaliation claims. These courts thus relied on the
    unique nature of the 1991 legislation to uncouple the causation standard
    of retaliation-based claims from status-based claims.
    Other federal courts seem to have taken a different approach.
    Although short of an express holding, the Seventh Circuit in Veprlinsky
    v. Fluor Daniel, Inc., cited the 1991 amendments establishing a
    motivating-factor causation test for status-based discrimination as also
    applying for treatment of retaliation claims. 
    87 F.3d 881
    , 886, 887 n.3
    (7th Cir. 1996); see also Hall v. City of Brawley, 
    887 F. Supp. 1333
    , 1345
    (S.D. Cal. 1995) (finding impermissible motivation, sustaining “same
    decision” defense, but affording statutory remedies permitted under Civil
    Rights Act of 1991 but not under Price Waterhouse). In de Llano v. North
    Dakota State University, the district court concluded that “it would be
    illogical and contrary to congressional intent to apply different standards
    of proof and accompanying relief provisions to retaliation claims as
    127
    opposed to discrimination claims.”       
    951 F. Supp. 168
    , 170 (D. N.D.
    1997).
    The fighting issue in this split was whether the employer was
    entitled to a complete same-decision affirmative defense under Price
    Waterhouse for retaliation claims, or whether the limitations of the same-
    decision defense contained in the 1991 Act were applicable.             See
    generally Lawrence D. Rosenthal, A Lack of “Motivation” or Sound Legal
    Reasoning? Why Most Courts Are Not Applying Either Price Waterhouse’s
    or the 1991 Civil Rights Act’s Motivating-Factor Analysis to Title VII
    Retaliation Claims in a Post-Gross World (But Should), 
    64 Ala. L
    . Rev.
    1067, 1070–73 (2013).
    2. Causation standard for claims under the Federal ADEA at
    variance with generally applicable federal status-based causation test. In
    Gross, the United States Supreme Court considered the question of
    causation in an age discrimination case brought under the ADEA. 557
    U.S. at 169–70, 129 S. Ct. at 2346. Unlike Iowa law, which has a unified
    statute, age discrimination in the federal regime is addressed in a
    separate statutory provision.
    In Gross, the Court considered the meaning of an ADEA provision
    which stated,
    It shall be unlawful for an employer . . . to fail or refuse to
    hire or to discharge any individual or otherwise discriminate
    against any individual with respect to his compensation,
    terms, conditions, or privileges of employment, because of
    such individual’s age.
    Id. at 182, 129 S. Ct. at 2353 (quoting 29 U.S.C. § 623(a)(1) (emphasis
    added)).
    The district court in Gross instructed the jury that liability could
    be based upon a determination that age was a motivating factor. 557
    128
    U.S. at 170–71, 129 S. Ct. at 2347. The jury returned a verdict in favor
    of the plaintiff. Id. at 171, 129 S. Ct. at 2347. On appeal, the Eighth
    Circuit reversed. Id. The Eighth Circuit ruled that because the plaintiff
    did not advance any direct evidence of age discrimination, the plaintiff
    was not entitled to a mixed-motive instruction under Price Waterhouse.
    Id.   While the question presented focused on whether a plaintiff must
    present direct evidence of age discrimination to obtain a mixed-motive
    jury instruction under the ADEA, the Supreme Court instead decided to
    answer the question of whether a mixed-motive instruction is even
    allowed under the ADEA. Id. at 173, 129 S. Ct. at 2348.
    In a 5–4 decision, the United States Supreme Court held that Price
    Waterhouse-type burden shifting did not apply to claims brought under
    the ADEA. Id. The reasoning of the Gross Court, however, is pertinent to
    this case. The Supreme Court stressed that in statutory interpretation,
    the court “must be careful not to apply rules applicable under one
    statute to a different statute without careful and critical examination.” Id.
    at 174, 129 S. Ct. at 2349. The Supreme Court emphasized that Title
    VII, after the 1991 amendments, expressly authorized mixed-motive
    analysis, while no similar change was introduced into the ADEA.           Id.
    Using dictionary definitions, the majority concluded that “because of” in
    the ADEA meant “but for” rather than the lesser standard in Price
    Waterhouse. Id. at 176–77, 129 S. Ct. at 2350.
    Obviously, the analysis in Gross of “because of” in the ADEA was
    at odds with the similar analysis of the exact same term in Title VII in
    Price Waterhouse.      There were now two competing approaches to
    “because of” in the United States Supreme Court precedents.             With
    respect to retaliation claims under Title VII, the question after Gross was
    whether the motivating-factor approach to “because of” in Price
    129
    Waterhouse would apply to retaliation claims under Title VII, or would
    the new Gross but-for test for “because of” supplant it
    3. Causation standard for federal retaliatory claims. In University
    of Texas Southwestern Medical Center v. Nassar, another bare 5–4
    majority of the Supreme Court held that the proper causation test for a
    retaliation claim under Title VII is the but-for test. 
    570 U.S.
    ___, ___, 
    133 S. Ct. 2517
    , 2534 (2013). The Nassar majority focused on the language
    of the Civil Rights Act of 1991.            Id. at ___, 133 S. Ct. at 2526.
    Specifically, the majority noted that in 1991, Congress required a
    motivating-factor causation test for status-discrimination claims, but did
    not expressly extend that standard to retaliation claims. Id. at ___, 133
    S. Ct. at 2529. The majority characterized this as a structural choice.
    Id.   The majority emphasized the importance of allowing Congress to
    choose its structure by differentiating between the status-discrimination
    and the retaliation provisions of Title VII.        Id.   The majority then
    compared the “because of” language in the ADEA with the “because of”
    language in the provision of Title VII. Id. at ___, 133 S. Ct. at 2528–29.
    Finding them similar, and finding the rationale of Gross equally
    applicable to the retaliation provision, the Supreme Court concluded that
    a but-for test for retaliation under Title VII was proper. Id. at ___, 133
    S. Ct. at 2533.     Interestingly, by its “structural” interpretation, the
    Supreme Court majority used the Civil Rights Act of 1991—which was
    designed to provide additional protections—to narrow protections under
    the retaliation provision of Title VII.
    The majority also offered a pragmatic justification for the but-for
    test. Citing increases in the number of retaliation claims with the EEOC,
    the majority stated that it was of “central importance” to the judicial
    system to limit the number of claims.         Id. at ___, 133 S. Ct. at 2531.
    130
    According to the majority, if the Court used a motivating-factor standard,
    frivolous claims would increase and judicial resources would be diverted
    from genuine efforts to combat discrimination. Id. at ___, 133 S. Ct. at
    2531–32.
    Justice    Ginsburg—joined      by    Justices      Breyer,   Kagan,      and
    Sotomoyor—dissented.       Id. at ___, 133 S. Ct. at 2534 (Ginsburg, J.,
    dissenting).     Justice   Ginsberg      maintained       that   “retaliation    for
    complaining     about   discrimination     is   tightly   bonded    to   the    core
    prohibition [of discrimination] and cannot be disassociated from it.” Id.
    Justice Ginsburg noted with irony that the majority utilized a statutory
    revision designed to strengthen the Civil Rights Act to weaken it in
    retaliation claims. Id. at ___, 133 S. Ct. at 2540–41. Justice Ginsburg
    argued that the 1991 Amendment to the Civil Rights Act applied to “any
    employment practice,” a phrase broad enough to include retaliation
    claims. Id. at ___, 133 S. Ct. at 2539. She rejected the conservation-of-
    resources argument, declaring that the majority was blinded by “a zeal to
    reduce the number of retaliation claims filed against employers.” Id. at
    ___, 133 S. Ct. at 2547.
    D. State Caselaw on Causation Standard for Retaliation
    Claims.
    1. Causation test on generally applicable discrimination. The vast
    majority of state courts have generally adopted a version of Price
    Waterhouse for status-based discrimination claims.               For instance, in
    Harvard v. Bushberg Brothers, Inc., the New Jersey court emphasized
    that discrimination on the basis of sex is shown if sex played at least a
    part and was a causal factor in the failure of the complainant to be
    promoted. 
    350 A.2d 65
    , 67 (N.J. Super. Ct. 1975). In Navy v. College of
    the Mainland, a Texas court noted some division in the federal cases
    131
    about required causation, but ultimately adopted a motivating-factor test
    based on the plain meaning of Texas law. 
    407 S.W.3d 893
    , 899 & n.3
    (Tex. App. 2013).
    2. Causation test regarding retaliation. State courts have adopted
    a wide range of tests for claims based on retaliatory conduct by an
    employer. They range from the least demanding a-factor test to the most
    demanding but-for test.
    In VECO, Inc. v. Rosebrock, the Alaska Supreme Court considered
    the standard for causation in a retaliation case.     
    970 P.2d 906
    , 920
    (Alaska 1999).      The Alaska court noted that under Price Waterhouse,
    “because” meant a “motivating part in an employment decision” and held
    that a plaintiff was required to meet the same test in a retaliation case
    under Alaska law.       Id.   In Mole v. University of Massachusetts, the
    Massachusetts court also considered causation in a retaliation case. 
    814 N.E.2d 329
    , 338 (Mass. 2004).        The Massachusetts court stated the
    plaintiff must show that “a causal connection existed between the
    protected conduct and the adverse action.” Id. at 339; see also Hollins v.
    Federal Nat’l Mortg. Ass’n, 
    760 A.2d 563
    , 579 (D.C. 2000).
    In Ruffin Hotel Corp. of Maryland, Inc. v. Gasper, the Maryland
    court considered the proper causation test in a retaliatory discharge
    case.    
    17 A.3d 676
    , 686 (Md. Ct. App. 2011).       The Maryland court
    adhered to a motivating-factor test in the retaliation context. Id. The
    Maryland court noted that in Price Waterhouse, the Supreme Court
    expressly rejected a but-for test for status discrimination, quoting Price
    Waterhouse for the proposition that to construe the words “because of”
    as a short hand for “but for” is “to misunderstand them.” Id. at 685.
    The Maryland court cited the Supreme Court’s handiwork in Desert
    Palace for the proposition that a motivating factor was sufficient to
    132
    establish causation in a Title VII status-classification claim. Id. (citing
    Desert Palace, 
    539 U.S. 90
    , 
    123 S. Ct. 2148
    ).
    Similarly, in Mele v. Hartford, the Connecticut Supreme Court
    considered the question of what a plaintiff must show in the context of a
    claim that the employer retaliated because of the plaintiff’s assertion of
    his right to workers’ compensation benefits. 
    855 A.2d 196
    , 206 (2004).
    The Connecticut court held the plaintiff must show that retaliatory
    motive “played a part” in the adverse employment action.       Id. at 211.
    Consistent with Mele, a Connecticut trial court expressly declined to
    follow the Nassar and Gross cases. Gonska v. Highland View Manor, Inc.,
    No. CV126030032S, 
    2014 WL 3893100
    , at *7 (Conn. Super. Ct. June 26,
    2014).   Instead, the Connecticut court adopted the McDonnell Douglas
    burden-shifting approach, coupled with the more lenient motivating-
    factor standard, which only requires a showing that a retaliatory motive
    contributed or played a part in the adverse action. Id.
    Missouri courts have developed a contributing-factor test for
    causation in retaliation cases.   See Turner v. Kan. City Pub. Sch., 
    488 S.W.3d 719
    , 723 (Mo. Ct. App. 2016); Williams v. Trans States Airlines,
    Inc., 
    281 S.W.3d 854
    , 866 (Mo. Ct. App. 2009); McBryde v. Tienour Sch.
    Dist., 
    207 S.W.3d 162
    , 170 (Mo. Ct. App. 2007). It is not entirely clear
    what “contributing” means or how it adds to the analysis.
    Some states have adopted a substantial-factor test. For instance,
    in Allison, the Washington Supreme Court adopted a substantial-factor
    test for retaliation claims under the Washington Human Rights Act. 821
    P.2d at 38. In rejecting the but-for test, the Washington Supreme Court
    emphasized the legislative instruction that Washington courts provide a
    liberal construction of the Act. Id. at 37. As a result, the Washington
    Supreme Court noted the local statute differed from Title VII, which did
    133
    not contain a liberal-construction directive. Id. at 38. The Washington
    Supreme Court concluded that a but-for causation standard would put
    an unrealistic burden on plaintiffs, limiting the ability of many plaintiffs
    to assert antidiscrimination claims. Id. at 42. On the other hand, the
    court rejected a “to any degree” standard advocated by the plaintiff. Id.
    According to the Washington court, even a slight retaliatory animus
    could be the basis of employer liability. Id. at 42. The Washington court
    characterized its substantial-factor test as an intermediate one. Id.; see
    also Rymal v. Baergen, 
    686 N.W.2d 241
    , 249 (Mich. Ct. App. 2004)
    (stating to establish causation in retaliation case, plaintiff must show
    illegal action was “a significant factor” in adverse action).
    In the above substantial-factor cases, it is not entirely clear how
    stringent the test is. In Lacasse v. Owen, the Oregon court suggests that
    the substantial-factor test is about the same as a but-for test. 
    373 P.3d 1178
    , 1183 (Or. Ct. App. 2016). This view, of course, is in variance with
    the Allison court, which interpreted the substantial-factor test as falling
    well short of the but-for test. See 821 P.2d at 85.
    The Supreme Court of California considered the standard for
    retaliation claims in Harris v. Santa Monica, 
    294 P.3d 49
    , 66 (Cal. 2013).
    The Harris court developed a substantial-motivating-factor or -reason
    test. Id. The court drew a distinction between a substantial-motivating
    factor and a motivating factor.         Id.   According to the court, the
    substantial-motivating-factor test ensured that liability would not be
    imposed “on evidence of mere thoughts or passing statements unrelated
    to the disputed employment decision.” Id.; see Alamo v. Practice Mgmt.
    Info. Corp., 
    161 Cal. Rptr. 3d 758
    , 769 (Ct. App. 2013) (reversing trial
    court judgment when instruction required a motivating factor instead of
    a substantial-motivating factor).    The court further decided that if an
    134
    employer demonstrated the decision would have been made in any event,
    that would not be a complete defense, but the plaintiff would still be
    entitled to injunctive relief and attorney’s fees. 294 P.3d at 68. In other
    words, the court adopted, through judicial decision, the approach in the
    Civil Rights Act of 1991 modifying Price Waterhouse.      See also King v.
    Cowboy Dodge, Inc., 
    357 P.3d 755
     (Wyo. 2015) (rejecting Nassar and
    adopting a “substantial and motivating” test, borrowed largely from
    workers’ compensation retaliation cases).
    Some state courts, however, have adopted the very stringent but-
    for test for retaliation claims.   For example, in Ashbury University v.
    Powell, the Kentucky Supreme Court summarized the majority argument
    in Nassar and accepted it under Kentucky law. 
    486 S.W.3d 240
    , 254–
    55 (Ky. 2016). Similarly, in Navy, the court declared, with little analysis,
    that there must be a substantial factor, and not just a causal link,
    supporting any retaliation claim. 407 S.W.3d at 899; see also Wholf v.
    Tremco Inc., 
    26 N.E.3d 902
    , 908 (Ohio Ct. App. 2015) (noting Ohio civil
    rights statute “modeled after Title VII” and embracing the reasoning of
    the Nassar majority). In Gorree v. United Parcel Service, Inc., a Tennessee
    appellate court applied the but-for test of Nasser in a retaliation case,
    noting the legislature in Tennessee intended Tennessee law “to be
    coextensive with federal law.”     
    490 S.W.3d 413
    , 439 (2015).      None of
    these cases discussed the impact of the 1991 Civil Rights Act nor the
    unique legislative history behind Title VII compared to state civil rights
    statutes.
    E. Iowa Caselaw on Causation Under ICRA.
    1. Generally   applicable    causation   standard   for   status-based
    discrimination. Our most recent exploration of causation in a claim of
    status-based discrimination was DeBoom v. Raining Rose, Inc., 772
    
    135 N.W.2d 1
    , 13 (Iowa 2009). In DeBoom, we emphasized the causation test
    for status-based discrimination under the ICRA was not “the determining
    factor” test but rather “a determining factor” test. Id. at 13–14 (emphasis
    added).   We further noted it was sufficient to show that status-based
    discrimination “played a part in the Defendant’s later actions toward
    Plaintiff.” Id. at 13.
    2. Causation in retaliation cases. In Hulme v. Barrett (Hulme II),
    
    480 N.W.2d 40
    , 42 (1992), we briefly considered the question of proof in
    a retaliatory discharge case.      In Hulme II, we declared in a brief
    paragraph that the causation standard for retaliation claims under the
    ICRA was a “high one.” Id. Citing one case from the Sixth Circuit but
    offering no analysis, we declared the “causal connection” required for a
    retaliation claim must be a “significant factor” motivating the adverse
    employment decision. Id. Notably, we used both the term “significant”
    and the term “motivating” to describe the causation requirement.        Id.
    After having stated that causation must be a significant factor motivating
    the adverse employment decision, we then cited another case from the
    Eighth Circuit applying a substantial-factor test. Id.; see Womack, 619
    F.2d at 1297.
    We returned to the causation question for retaliation claims in City
    of Hampton v. Iowa Civil Rights Commission, 
    554 N.W.2d 532
     (Iowa
    1996). The brief discussion of causation in City of Hampton was dicta as
    no argument regarding level of causation was presented to the Iowa Civil
    Rights Commission.       See id. at 535–36.   In City of Hampton, we cited
    Hulme II for the proposition that in retaliation cases, causation is
    established by a “significant factor” motivating the adverse employment
    decision. Id. We did not cite the motivating-factor language in Hulme II.
    We again cited the Womack case, but this time for the proposition that
    136
    the Eighth Circuit had established a but-for test and not a substantial-
    factor test as suggested in Hulme II.          Id.   We also cited, without
    elaboration, a Sixth Circuit case under Michigan law supporting a
    significant-factor standard.    Id. (citing Polk v. Yellow Freight Sys., Inc.,
    
    801 F.2d 190
     (6th Cir. 1986)).
    In Hulme II and City of Hampton, we did not review the underlying
    statutory text of the ICRA. We did not engage in a reasoned discussion
    of the available interpretative options. We did not consider the impact of
    Iowa Code section 216.18(1) requiring that we “broadly interpret the act
    to effectuate its purposes.”     In fact, there is no analysis at all, only
    ambiguous and inconsistent declarations regarding a substantial-factor
    test and a motivating-factor test.
    F. Analysis.      I   begin   the   discussion   of   causation   with
    consideration of the proper level of causation required to sustain a
    retaliation claim. Under the unified ICRA, the legislature has used the
    same term for causation for both status-based discrimination and
    retaliation claims, namely, the familiar “because” and “because of”
    language.    Iowa Code §§ 216.6(1)(a), .11(2).       Two conclusions may be
    drawn from the use of the “because” and “because of” causation
    language in both the status-based and the retaliation sections of the
    ICRA.
    First, there is a strong textual argument that the level of causation
    for status-based claims and retaliation claims should be the same. We
    have frequently said that when the same term appears multiple times in
    the same statute, it should have the same meaning. State v. Paye, 
    866 N.W.2d 1
    , 7 (Iowa 2015); accord Carson v. Roediger, 
    513 N.W.2d 713
    ,
    716 (Iowa 1994); State v. Johnson, 
    604 N.W.2d 669
    , 672 (Iowa Ct. App.
    1999). This familiar rule has been applied repeatedly in the context of
    137
    civil rights statutes. See, e.g., EEOC v. Fry’s Elecs., Inc., 
    770 F. Supp. 2d 1168
    , 1171 (W.D. Wash. 2011); Patino v. Birken Mfg. Co., 
    41 A.3d 1031
    ,
    1041 (Conn. 2012); San Antonio v. Baer, 
    100 S.W.3d 249
    , 253 (Tex. App.
    2001); see generally 3B Norman J. Singer & Shambie Singer, Statutes
    and Statutory Construction § 76.9, at 205 & n. 11 (7th ed. 2011).
    Further, there is no policy reason to question the legislative
    judgment to use nearly identical causation language, thereby implying
    the same level of causation for retaliation claims as well as for status-
    based discrimination.     As indicated above, retaliation claims are not
    second-class citizens, but are critical to effective enforcement of the
    ICRA.     Policy reasons do not provide a basis for overriding the
    legislature’s textual choice.
    Indeed, status-based discrimination and retaliation claims are two
    halves of the same walnut.       The success of each depends upon the
    efficacy of the other.    Nassar, 
    570 U.S.
    at ___, 133 S. Ct. at 2531.
    Retaliation for complaining about discrimination is tightly bonded to the
    core prohibition and cannot be disassociated from it.         Id.   Thus, in
    addition to the textual argument based upon common use of the
    because-of causation standard in both status-based discrimination
    claims and retaliation provisions under the ICRA, there is also a strong
    functional argument for utilizing the same legal standard. Indeed, the
    United States Supreme Court, prior to its innovation in Nassar,
    repeatedly held that retaliation was a type of status discrimination. See
    Jackson v. Birmingham Bd. of Educ., 
    544 U.S. 167
    , 174, 
    125 S. Ct. 1497
    ,
    1504 (2005).
    This approach represents a refinement, perhaps, of the standard
    for retaliation claims under the ICRA used in Hulme II and City of
    Hampton.      In these cases, we applied a substantial-factor test for
    138
    retaliation claims under the ICRA. City of Hampton, 554 N.W.2d at 535–
    36; Hulme II, 480 N.W.2d at 43.         I do not believe there is a great
    difference between the substantial-factor test in Hulme II and City of
    Hampton and the motivating-factor or played-a-part test in DeBoom. But
    to the extent there is any distance between the two standards, this case
    presents an opportunity to close that distance.
    By adopting a unified approach to status-based and retaliation
    causation, we would avoid juror confusion. We would avoid what Justice
    Ginsberg noted would be the result in Nassar, namely, that different
    causation standards would cause jurors to “puzzle over the rhyme or
    reason for the dual standards.”     
    570 U.S.
    at ___, 133 S. Ct. at 2535.
    Such a double standard would be “virtually certain to sow confusion” in
    its practical application.   Id. at ___, 133 S. Ct. at 2546.   The different
    standards are made even more problematic by the fact that the status-
    based and retaliatory conduct will have an overlapping or “symbiotic
    relationship,” as Justice Ginsberg suggested.     Id. at ___, 133 S. Ct. at
    2535. Retaliation is simply another form of sex discrimination. Jackson,
    544 U.S. at 174, 125 S. Ct. at 1504.          I would thus conclude the
    motivating-factor or played-a-part test that applies for status-based
    discrimination should also apply in retaliation claims under the ICRA.
    In reaching this conclusion, I note the Nassar case has no bearing
    in the interpretation of the ICRA.      The legislative history behind the
    status-classification and retaliation provisions of Title VII discussed in
    Nassar is fundamentally different than the legislative history behind the
    ICRA.     Nassar relied extensively on the difference in congressional
    language between causation for status-based claims and causation for
    retaliation claims that arose after the enactment of the Civil Rights Act of
    1991. 
    570 U.S.
    at ___, 133 S. Ct. at 2529 (majority opinion).
    139
    In light of the Civil Rights Act of 1991, the text of Title VII is now
    fundamentally different than the text of the ICRA with respect to the
    causation requirements in status-based and retaliation cases.        Under
    Title VII, the motivating-factor test was explicitly incorporated into
    status-based discrimination, but the same change was not introduced
    into the retaliation section of Title VII. Here, our caselaw has defined
    causation in the status-based discrimination clause as being a
    motivating factor and the same causation language is used in the
    retaliation section of the ICRA.       The reasoning of Nassar is thus
    completely inapplicable here.
    Aside from the markedly different legislative history, I would reject
    Nassar for other reasons. In particular, I am unpersuaded by the notion
    that higher standards for a retaliation claim are required in light of the
    number of complaints filed with the EEOC. At the outset, it is odd that a
    provision of substantive law should be affected by the number of
    administrative complaints made to an agency responsible under a
    statute to adjust such claims. If the number of claims decreases to a
    trickle, does that provide a basis for lessening the substantive
    standards?    Can it be that a substantive legal standard expands and
    contracts based upon its use?
    Further, it makes no sense to limit relief for very substantial and
    powerful claims, like those in Nassar, in order to also limit frivolous
    claims.   Other tools are available.   A charge of discrimination may be
    filed under the ICRA only under penalty of perjury. A court may award
    attorneys’ fees as a sanction for claims brought in bad faith. Attorneys
    who file false claims are subject to ethical sanctions.      See generally
    Sandra F. Sperino & Suja A. Thomas, Fakers and Floodgates, 10 Stan. J.
    C.R. & C.L. 223, 228 (2014).       Further, there is no evidence that a
    140
    heightened standard of causation would deter false claims.                     A person
    willing to file a false claim is not likely to be affected by a higher
    substantive causation standard.
    Further, the mere existence of an increase in EEOC claims is not a
    powerful empirical tool. The executive branch, through an amicus brief
    filed by the United States Department of Justice, did not advance the
    argument and supported the lower motivating-factor standard for
    discrimination claims. See Brief for the United States as Amicus Curiae
    Supporting Respondent at 7, Nassar, 
    570 U.S.
    ___, 
    133 S. Ct. 2517
     (No.
    12-484), 
    2013 WL 1462056
    , at *7.                 Further, the EEOC—through its
    guidelines—advocated a motivating-factor standard.                  U.S. Equal Emp’t
    Opportunity Comm’n, EEOC Compliance Manual: EEOC Directives
    Transmittal No. 915.003 (May 20, 1998), https://web.archive.org/

    [hereinafter EEOC Manual 1998 Update] (replacing section 614 in the
    1991 Manual); see also 2 U.S. Equal Emp’t Opportunity Comm’n, EEOC
    Compliance Manual § 614.3(e), at 614–10 (Dec. 1, 1991) (stating the
    protected action must be “at least a factor” in the retaliation). Thus, the
    agency principally responsible for dealing with workplace discrimination,
    the EEOC, did not raise the argument itself about filing of frivolous
    claims and siphoning of its resources. 32
    The majority in Nassar believed it was in a better position to judge
    the administrative impact of substantive retaliation law on filings. See
    32See also U.S. Equal Emp’t Opportunity Comm’n, Theories of Discrimination:
    Intentional and Unintentional Employment Discrimination A–19 (May 1995) (“The
    retaliation provisions [of the EPA, ADA, and ADEA] provide exceptionally broad
    protection to individuals who file charges or otherwise aid the EEOC’s enforcement
    function. It is the EEOC’s policy to expedite the investigation of retaliation charges and
    seek injunctive relief, since it has the unique interest of preserving the integrity of its
    investigative process and preventing a chilling effect on the willingness of individuals to
    protest discriminatory conduct.”).

    570 U.S.
    at ___, 133 S. Ct. at 2531–32. Yet, the Nassar Court had no
    evidence of the reasons for the increase in retaliation claims.        The
    increase in claims may reflect an increased awareness of the availability
    of remedies.   And, the failure to report civil rights claims for fear of
    retaliation may well continue to be an intractable problem that should
    not be exacerbated by imposing a higher substantive law standard on
    causation. See Deborah L. Brake & Joanna L. Grossman, The Failure of
    Title VII as a Rights-Claiming System, 
    86 N.C. L
    . Rev. 859, 897–900
    (2008); Deborah L. Brake, Retaliation, 
    90 Minn. L
    . Rev. 18, 25–26 (2005)

    Litigation as a Claiming System, 
    2005 Wis. L
    . Rev. 663, 673–75 (2005).
    As noted in Crawford v. Metropolitan Government of Nashville & Davidson
    County, “[f]ear of retaliation is the leading reason why people stay silent
    instead of voicing their concerns about bias and discrimination.”      
    555 U.S. 271
    , 279, 
    129 S. Ct. 846
    , 852 (2009) (quoting Brake, Retaliation, 
    90 Minn. L
    . Rev. at 20).     The higher standard is inconsistent with the
    unfettered access to the remedial system espoused in Smith v. Jackson,
    
    544 U.S. 228
    , 233, 
    125 S. Ct. 1536
    , 1540–41 (2005).
    In the end, once the Nassar rhetoric is examined, the majority
    appears to have been motivated by “zeal to reduce the number of
    retaliation claims filed against employers.” 
    570 U.S.
    at ___, 133 S. Ct. at
    2547 (Ginsberg, J., dissenting). The lowered protection from retaliation
    will tend to defeat the early reporting of harassment claim and their
    prompt adjustment.      Ernest F. Lidge, III, The Necessity of Expanding
    Protection from Retaliation for Employees Who Complain About Hostile
    Environment Harassment, 453 U. Louisville L. Rev. 39, 56 (2014). The
    approach in Nassar is inconsistent with the observation in Burlington
    142
    Northern that “[i]nterpreting the antiretaliation provision to provide broad
    protection from retaliation helps ensure the cooperation upon which
    accomplishment of the Act’s primary objective depends.” 548 U.S. at 67,
    126 S. Ct. at 2414. And certainly the flavor of the majority opinion in
    Nassar does not reflect the command of Iowa Code section 218.1(2) to
    broadly construe provisions of the ICRA.
    Based on the above reasoning, we conclude the reasoning of
    Nassar should be rejected under the ICRA. The “because of” language in
    the status-based discrimination provision of the ICRA should be
    interpreted the same as the “because of” language for retaliation claims.
    We have not used identical language in our past cases dealing with
    causation in retaliation cases. In Hulme II, 480 N.W.2d at 43, and City of
    Hampton, 554 N.W.2d at 535, we used the substantial-factor language,
    but in DeBoom, 772 N.W.2d at 13, we employed the motivating-factor or
    played-a-part test.
    There are two ways to address the apparent difference in the
    language of our cases.     One is to simply state that the difference in
    language in the cases inconsequential and that the instruction in this
    case was sufficient on the law.        That is the position taken by a
    commentator after review of the disparate federal caselaw of retaliation
    causation.   Martin J. Katz, The Fundamental Incoherence of Title VII:
    Making Sense of Causation in Disparate Treatment Law, 94 Geo L.J. 489,
    at 507–10 (2006) (indicating there is no difference between “substantial
    factor” and “motivating factor” formulations but, as between the two,
    endorsing an “a factor,” “a role,” or “a motivating factor” formulation.).
    To the extent there is a difference, however, we would go with our more
    recent formulation in DeBoom, 772 N.W.2d at 13, where the issue of level
    of causation was a contested issue, and not with the older approach in
    143
    Hulme II, 480 N.W.2d at 43, and City of Hampton, 554 N.W.2d at 535,
    where the question of level of causation was not disputed by the parties.
    The DeBoom causation test, to the extent it is different than the
    approach in Hulme II and City of Hampton, is more protective of the
    channels of communication that are so essential to the effective
    enforcement of the ICRA.
    V. Instructions Regarding “Materially Adverse Action” in
    Retaliation Cases.
    A. Overview of Issue.       Neither the ICRA nor federal statute
    requires a plaintiff make a showing of a “materially adverse action” in
    order to support a retaliation claim.    Nonetheless, the United States
    Supreme Court has grafted such a requirement onto Title VII and many
    courts have followed the Supreme Court’s lead. See Burlington Northern,
    548 U.S. at 68, 126 S. Ct. at 2415 (“In our view, a plaintiff must show
    that a reasonable employee would have found the challenged action
    materially adverse . . . .”); Rachel K. Alexander, Taking the Detour Around
    Defending Protected Activity: How Burlington Northern v. Santa Fe
    Railway Co. v. White Unnecessarily Complicates Litigation of Retaliation
    Claims, 27 Rev. Litig. 333, 350–52 (2008) (describing that the materially-
    adverse-action standard has been read into state antidiscrimination
    statutes by courts).
    The parties in this case do not contest the basic proposition that a
    plaintiff in a retaliation case must show materially adverse action. The
    question is, instead, whether the trial court’s instructions accurately
    described adverse action necessary to support a retaliation claim under
    the ICRA.
    144
    B. Challenged Trial Court Instructions.        The district court’s
    instruction defined “adverse actions” required to support a retaliation
    claim under the ICRA as follows:
    [A]ny action which has material consequences to an
    employee. It is anything that might dissuade a reasonable
    person from making or supporting an allegation of
    discrimination or harassment.
    It includes but is not limited to such employment
    actions as constructive discharge, reprimands or other
    threats of reprimands, a change in opportunities, false
    accusations or complaints, being investigated, being placed on
    performance improvement plan, being placed on probation or
    other actions which adversely affect or undermine the position
    of the employee. It also includes an employer seeking out
    negative feedback on an employee or condoning or
    encouraging other employees to complain about her. You
    should judge whether an action is sufficiently adverse from
    the point of view of a reasonable person in the plaintiff’s
    positions.
    (Emphases added.)
    HES had offered the following instruction on adverse action:
    [A]n “adverse employment action” is an action that
    detrimentally affects the terms, conditions, or privileges or
    employment. Changes in duties or working conditions that
    cause no materially significant disadvantage to the employee
    are not adverse employment actions. It includes, but is not
    limited to, employment actions such as termination of
    employment, failure to promote, or any action that would
    discourage a reasonable employee from making a complaint
    of harassment.       Giving an employee a performance
    improvement plan or negative employment review is not
    “adverse employment action” unless they are later used as a
    basis to alter the employee’s terms or conditions of
    employment in a detrimental way. Both the action and its
    context must be examined.
    C. Positions of the Parties.       HES asserts the district court’s
    instruction was inaccurate because it includes actions which do not
    “materially significantly disadvantage” the employee. According to HES,
    145
    no court has ever found the actions italicized in the instructions to
    amount to an adverse employment action.
    Haskenhoff notes the first paragraph of the instruction provides
    that in order to be an adverse action, the action must have “material
    consequences” for the employee. Further, the jury found Haskenhoff was
    constructively discharged.     Thus, the jury plainly found there was a
    legally sufficient adverse action by the employer.       As a result, to the
    extent the instruction is flawed, Haskenhoff argues it is harmless.
    D. Federal    Caselaw      and      EEOC    Authority   on    Scope    of
    “Materially Adverse Action” in the Context of Retaliation Claims.
    1. Introduction. With respect to retaliation, Title VII states that it
    is an unlawful employment practice for an employer “to discriminate
    against any of his employees . . . because he has opposed any practice
    made an unlawful employment practice by this subchapter, or because
    he has made a charge, testified, assisted, or participated in any manner
    in an investigation proceeding or hearing under this subchapter.”            42
    U.S.C. § 2000e-3(a). The phrase “to discriminate” is not defined by the
    statute. Congress left that question for the courts. Unlike the status-
    discrimination provision of Title VII, however, the retaliation provision
    does not contain the phrase “terms, conditions, or privileges of
    employment.”     42 U.S.C. § 2000e-2(a).         The presence of the phrase
    “terms,   conditions,   or   privileges   of   employment”    in   the   status-
    discrimination section of Title VII, when it is excluded in the retaliation
    provision, gives rise to the inference that Congress has made a deliberate
    choice.
    2. EEOC 1998 guidelines. The EEOC has confronted the question
    of what constitutes adverse action sufficient to support a retaliation
    claim under Title VII in revisions to its compliance manual issued in
    146
    1998. See EEOC Manual 1998 Update. According to the EEOC, while
    the “most obvious types of retaliation are denial of promotion, refusal to
    hire, denial of job benefits, demotion, suspension, and discharge”
    retaliation can also include “threats, reprimands, negative evaluations,
    harassment, or other adverse treatment.”        Id.; see EEOC v. Bd. of
    Governors of State Colls. & Univs., 
    957 F.2d 424
     (7th Cir. 1992);
    Christopher v. Strouder Mem’l Hosp., 
    936 F.2d 870
    , 873–74 (6th Cir.
    1991); Johnson v. Palma, 
    931 F.2d 203
     (2d Cir. 1991).
    The EEOC, however, rejected the “ultimate employment action”
    test adopted by the Eighth Circuit in Ledergerber v. Strangler, 
    122 F.3d 1142
     (8th Cir. 1997), and the “terms and conditions of employment” test
    embraced by the Fourth Circuit in Munday v. Waste Management of
    North America, 
    126 F.3d 239
     (4th Cir. 1997).         EEOC Manual 1998
    Update. According to the EEOC, such tests were “unduly restrictive.” Id.
    While the EEOC recognized that “petty slights and trivial annoyances are
    not actionable,” it stressed the degree of harm suffered by the individual
    “goes to the issue of damages, not liability.” Id. (quoting Hashimoto v.
    Dalton, 
    118 F.3d 671
    , 676 (9th Cir. 1997)).
    The EEOC justified its approach based on text and policy. On text,
    the EEOC emphasized that while the status discrimination of Title VII
    states it is unlawful to discriminate against a person with respect to
    “terms, conditions, or privileges of employment,” the retaliation provision
    of Title VII has no such limitation. EEOC Manual 1998 Update; see 42
    U.S.C. § 2000e-2.
    On policy, the EEOC emphasized the primary purpose of the
    antiretaliation provisions is to “maintain[ ]unfettered access to the
    statute’s remedial mechanisms.”    EEOC Manual 1998 Update; see also
    Robinson v. Shell Oil Co., 
    519 U.S. 337
    , 345, 
    117 S. Ct. 843
    , 848 (1997).
    147
    According to the EEOC, an interpretation of Title VII “that permits some
    forms of retaliation to go unpunished would undermine the effectiveness
    of the EEOC statutes and conflict with the language and purpose of the
    anti-retaliation provisions.”   EEOC Manual 1998 Update; see generally
    Joel A. Kravetz, Deterrence v. Material Harm: Finding the Appropriate
    Standard to Define an “Adverse Action” in Retaliation Claims Brought
    Under the Applicable Equal Employment Opportunity Statutes, 4 U. Pa. J.
    Lab. & Emp. L. 315, 355–65 (2002).
    3. The Burlington Northern case.      Prior to the seminal United
    States Supreme Court case of Burlington Northern, the federal courts
    splintered on the question of what a plaintiff must show to support a
    retaliation claim under Title VII.
    In Ray v. Henderson, the Ninth Circuit outlined the differing
    approaches to retaliation claims in the various circuits. 
    217 F.3d 1234
    ,
    1241–42 (9th Cir. 2000). According to Ray, the First, Seventh, Tenth,
    Eleventh, and D.C. Circuits all “take an expansive view” of the type of
    actions that can be considered adverse employment actions. Id. at 1241;
    see Wideman v. Wal-Mart Stores, 
    141 F.3d 1453
    , 1456 (11th Cir. 1998);
    Knox v. Indiana, 
    93 F.3d 1327
    , 1334 (7th Cir. 1996); Corneveaux v.
    CUNA Mut. Ins. Grp., 
    76 F.3d 1498
    , 1507 (10th Cir. 1996); Wyatt v.
    Boston, 
    35 F.3d 13
    , 15–16 (1st Cir. 1994); Passer v. Am. Chem. Soc., 
    935 F.2d 322
    , 330–31 (D.C. Cir. 1991). In contrast, Ray cited the Second
    and Third Circuits as holding adverse action is something that
    “materially affects the terms and conditions of employment.” 217 F.3d at
    1242; see Robinson v. Pittsburgh, 
    120 F.3d 1286
    , 1300 (3d Cir. 1977);
    Torres v. Pisano, 
    116 F.3d 625
    , 640 (2d Cir. 1997).    Finally, the Ray
    court noted the Fifth and Eighth Circuits had adopted the most
    restrictive test, namely, the “ultimate employment action” test which
    148
    required actions such as hiring, firing, promoting, and demoting to
    support a retaliation claim. 217 F.3d at 1242; see Mattern v. Eastman
    Kodak Co., 
    104 F.3d 702
    , 707 (5th Cir. 1997); Ledergerber, 122 F.3d at
    1144.
    In 2006, the Supreme Court entered the fray in Burlington
    Northern, 548 U.S. at 53, 126 S. Ct. at 2405. Under Burlington Northern,
    a plaintiff must show an employment action is materially adverse, “which
    in this context means it well might have dissuaded a reasonable worker
    from making or supporting a charge of discrimination.” Id. at 68, 126
    S. Ct. at 2415.      In so concluding, the court rejected the “terms,
    conditions,   or   benefits”   and   the    “ultimate   employment   decision”
    standards percolating through the federal courts in the Second, Third,
    Fifth, and Eighth Circuits. Id. at 61–63, 126 S. Ct. at 2411–12.
    In Burlington Northern, the Supreme Court adopted a general,
    functional approach to the retaliation provision of Title VII. See id. at 68,
    126 S. Ct. at 2415. The Burlington Northern Court tied material adversity
    directly to the purpose of the retaliation provision of Title VII—
    encouraging unfettered access to Title VII.       Id. at 62–63, 126 S. Ct. at
    2411–12. In determining whether the employer’s action “might well have
    dissuaded a reasonable worker from making or supporting a charge of
    discrimination,” the Court instructed that the question be determined
    from “the perspective of a reasonable person in the plaintiff’s position
    under all the circumstances.”        Id. at 71, 126 S. Ct. at 2417.    Under
    Burlington Northern, trial courts are required to examine the specific facts
    from someone in the plaintiff’s position, a highly individualized inquiry.
    See id.
    Thus, as the Burlington Northern Court repeatedly emphasized,
    “context matters” because an “act that would be immaterial in some
    149
    situations is material in others.”    Id. at 69, 126 S. Ct. at 2416.      The
    Supreme Court emphasized “the significance of any given act of
    retaliation will often depend upon the particular circumstances.” Id. The
    inquiry is fact specific to the workplace and to the individual pressing the
    retaliation claim. Id. The plain implication is that except in the most
    marginal of cases, because of their fact intensive nature, retaliation
    claims should survive summary judgment.
    4. Post-Burlington Northern federal caselaw. Burlington Northern
    was something of a bombshell in the employment law world.              As a
    general matter, there seemed to be little question that under Burlington
    Northern, more retaliation cases would survive summary judgment.
    Further, most of the post-Burlington Northern federal caselaw recognized
    that in determining whether a plaintiff has suffered disparate treatment,
    the “terms, conditions, and privileges of employment” test was not
    applicable in retaliation cases. The lower federal courts widely came to
    recognize that in retaliation cases, a lesser standard applies. See Powell
    v. Lockhart, 
    629 F. Supp. 2d 23
    , 41 (D.D.C. 2009) (holding that placing
    employee on performance improvement plan was insufficient to support
    disparate treatment claim, but could support retaliation claim because of
    lesser standard).
    Burlington Northern emphasized the proper test for a retaliation
    case was “material adverse action” which “well might have dissuaded a
    reasonable   worker     from   making      or   supporting   a   charge    of
    discrimination.”    548 U.S. at 68, 126 S. Ct. at 2415.      This feature of
    Burlington Northern appears to be lost in some of the cases, which seem
    to require tangible impact on “terms, conditions, and privileges of
    employment.” See Sutherland v. Mo. Dep’t of Corrs., 
    580 F.3d 748
    , 752
    (8th Cir. 2009) (rejecting adverse employment action when plaintiff “had
    150
    no reductions in pay, salary, benefits, or prestige”). And, in other cases,
    the test applied by the courts seems to be too high.         For example, in
    Deleon v. Kalamazoo County Road Commission, the Sixth Circuit
    suggested in a retaliation case that the question was whether a
    reassignment without loss of pay was “objectively intolerable” to a
    reasonable person. 
    739 F.3d 914
    , 919 (6th Cir. 2014). This formulation
    seems to be more demanding than a Burlington Northern standard where
    the plaintiff must show that a reasonable person “might well have been
    deterred” from supporting or filing a charge.
    Many post-Burlington Northern cases recognize that the totality of
    the circumstances must be considered when the “might well have
    deterred” standard is applied and bright-line declarations about whether
    certain   actions   were   sufficient    or   insufficient   were   generally
    inappropriate under Burlington Northern.           For example, following
    Burlington Northern, the Fifth Circuit in Thompson v. Waco, held that a
    change in job responsibilities did not automatically qualify as an adverse
    impact, but it could be adverse action depending upon a jury’s view of
    the facts. 
    764 F.3d 500
    , 504–05 (5th Cir. 2014).
    A related concept is that certain actions individually might not be
    sufficient, but cumulatively such actions may arise to adverse action for
    purposes of supporting a retaliation claim. For example, in Sanford v.
    Main Street Baptist Church Manor, Inc., the Sixth Circuit recognized that
    although some of the incidents might not rise to the level of adverse
    action, “the incidents taken together might dissuade a reasonable worker
    from making or supporting a discrimination charge.” 327 F. App’x 587,
    599 (6th Cir. 2009); see also Vega v. Hempsted Union Free Sch. Dist., 
    801 F.3d 72
    , 90 (2d Cir. 2015) (finding combination of being assigned absent
    students, temporary paycheck reduction, and failure to notify of
    151
    curriculum claim cumulatively amount to “material adverse action”);
    Alvarado v. Fed. Express Corp., 384 F. App’x 585, 589 (9th Cir. 2010)
    (holding delayed paychecks, denial of personal time, criticism of work
    performance, and shift change were adverse actions); Shannon v.
    Bellsouth Telecomm., Inc., 
    292 F.3d 712
    , 715–16 (11th Cir. 2002) (stating
    reassignment alone is not adverse action, but reassignment, together
    with denial of overtime and allocation of a more difficult assignment in
    an unairconditioned van, amounted to adverse action); Ridley v. Costco
    Wholesale Corp., 217 F. App’x 130, 135 (3d Cir. 2007) (holding while jury
    verdict finding demotion was not retaliatory, combination of other events
    after demotion, including transfer to warehouse, counseling notices for
    minor incidents, and failure to investigate these incidents satisfied
    Burlington Northern test); see generally Joan M. Savage, Adopting the
    EEOC Deterrence Approach to the Adverse Employment Action Prong in
    Prima Facie Case for Title VII Retaliation, 46 B.C. L. Rev. 215, 235–36
    (advocating broad case-by-case approach).
    Burlington    Northern   recognized   that   petty   slights,   minor
    annoyances, and simple lack of good manners is not enough to establish
    material adverse action to support a retaliation claim.      Some federal
    courts have regarded this declaration as an invitation to take a laundry-
    list approach and declare, as a matter of law, that certain types of
    actions never amount to material adverse actions. Other federal cases,
    however, are more sensitive to context.
    5. EEOC August 2016 enforcement guidelines on retaliation and
    related issues.    In August 2016, the Equal Employment Opportunities
    Commission issued its “Enforcement Guidelines on Retaliation and
    Related Issues,” superseding its previous guidance in 1998. See EEOC
    Enforcement Guidance on Retaliation and Related Issues (Aug. 25, 2016),
    152
    https://www.eeoc.gov/laws/guidance/retaliation-guidance.cfm
    [hereinafter EEOC Enforcement Guidance]. The new guidelines generally
    embraced Burlington Northern and provided the commission’s view of
    retaliation claims in a post-Burlington Northern world. Id. II.B.1.
    Among other things, the EEOC emphasized that combinations of
    incidents could cumulatively amount to a material adverse action even if
    the individual incidents, considered alone, might not qualify. Id. The
    EEOC further emphasized that under Burlington Northern, potential
    retaliatory incidents must be considered in context and not in isolation.
    Id.
    The EEOC addressed the question of what type of actions might
    rise to the level of a material adverse action. Id. II.B.2. According to the
    EEOC, “[t]he most obvious types of adverse actions are denial of
    promotion, refusal to hire, denial of job benefits, demotion, suspension,
    and discharge.” Id. But the EEOC went on to say,
    Other types of adverse actions may include work-related
    threats, warnings, reprimands, transfers, negative or lowered
    evaluations, transfers to less prestigious or desirable work or
    work locations, and any other types of adverse treatment
    that in the circumstances might well dissuade a reasonable
    person from engaging in protected activity.
    Id.
    The EEOC concluded the determination of whether a plaintiff has
    made the necessary showing of material adverse action to support a
    retaliation claim was fact driven. Id. According to the EEOC,
    A fact–driven analysis applies to determine if the challenged
    employer action(s) in question would be likely to deter
    participation or opposition. To the extent some lower courts
    applying Burlington Northern have found that some of the
    above-listed actions can never be significant enough to deter
    protected activity, the Commission concludes that such a
    categorical view is contrary to the context-specific analysis,
    153
    broad reasoning, and specific examples endorsed by the
    Supreme Court.
    Id.
    The EEOC also addressed the question of whether a materially
    adverse action required harm to the employee. Id. The EEOC concluded
    it did not. Id. According to the EEOC, the degree of harm suffered by the
    individual “goes to the issue of damages, not liability.”    Id. (quoting
    Hashimoto v. Dalton, 
    118 F.3d 671
    , 675 (9th Cir. 1997)).
    Finally, the EEOC distinguished between the standard required to
    prove a hostile environment claim and the standard to show retaliation.
    Id. As noted by the EEOC, “[t]he threshold for establishing retaliatory
    harassment is different than for discriminatory hostile environment.” Id.
    II.B.3.
    According to the EEOC, harassment sufficient to support a retaliation
    claim does not need to be severe or pervasive enough to alter the terms
    and conditions of employment. Id.
    E. State Caselaw on Retaliation Requirements.         Neither party
    cited any state caselaw on the question of what constituted adverse
    action sufficient to support a retaliation claim.   We have been able to
    discern no clear pattern in the state caselaw.
    Some state cases recognize the impact of Burlington Northern. For
    instance, in Donovan v. Broward County Board of Commissioners, a
    Florida court of appeals recognized that Burlington Northern found the
    ordinary approach to discrimination cases too limiting in the context of
    retaliation claims. 
    974 So. 2d 458
    , 461 (Fla. Dist. Ct. App. 2008). The
    Donovan court applied the broadened Burlington Northern standard. Id.
    Another case that employs Burlington Northern contextualization is
    Ellis v. Jungle Jim’s Market, Inc., 
    44 N.E.3d 1034
     (Ohio Ct. App. 2013).
    154
    In Ellis, an employee was transferred from the seafood department into a
    bagging position after reporting workplace harassment. Id. at 1052. The
    plaintiff produced evidence that the transfer significantly diminished her
    job responsibilities and that she would learn fewer skills in the bagging
    position. Id. at 1053–54. The Ohio court held that she raised an issue of
    fact with respect to whether the transfer amounted to a “material adverse
    action” by her employer. Id. at 1054.
    Similarly, in Hoffelt v. Illinois Department of Human Rights, a
    plaintiff claiming retaliation offered evidence that she was called names
    and treated in a demeaning manner, was assigned to a position known
    as “a punishment post,” and had her requests for compensatory leave
    denied under circumstances in which they were granted in the past. 
    867 N.E.2d 14
    , 21 (Ill. Ct. App. 2006). Citing Burlington Northern, the Illinois
    court concluded that under the circumstances, she “well might have
    dissuaded a reasonable worker from making or supporting a charge of
    discrimination.” Id. at 20.
    Another state court has emphasized the need to broadly construe
    the retaliation provision in its civil rights legislation. In Albunio v. City of
    New York, the court emphasized the retaliation provision would be
    construed “broadly in favor of discrimination plaintiffs, to the extent
    such a construction is possible.” 
    847 N.E.2d 135
    , 137 (N.Y. 2011); see
    also Roa v. Roa, 
    955 A.2d 930
    , 938 (N.J. Super. Ct. App. Div. 2008)
    (adopting Burlington Northern approach).          At least one state court,
    however,   has    characterized    the   Burlington   Northern   inquiries   as
    ordinarily posing questions of law. In Montgomery County v. Park, the
    Texas Supreme Court held that changes in a job position did not support
    a retaliation claim. 
    246 S.W.3d 610
    , 615–16 (Tex. 2007).
    155
    F. Iowa Caselaw on “Adverse Employment Action.”                   We have
    considered the meaning of “adverse employment action” 33 in a limited
    number of cases.        In most of them we have indicated what the vague
    term “adverse employment action” might include, not what it excludes.
    In the pre-Burlington Northern case of Channon v. United Parcel Service,
    Inc., we noted that “[a] wide variety of actions, some blatant, some
    subtle,” can qualify as “adverse employment actions.” 
    629 N.W.2d 835
    ,
    863 (Iowa 2001).       Indeed, we have indicated that whether an adverse
    employment action occurred “will normally depend on the facts of each
    situation.” Id. at 862. This fact-specific language is consistent with the
    strain in the federal law that recognizes, as did Burlington Northern, that
    the determination is to be made under all of the facts and circumstances.
    See 548 U.S. at 71, 126 S. Ct. at 2417. We cited with approval cases
    that found loss of title and committee assignments, transfers, and
    reduction of supervisor status as amounting to “adverse employment
    actions.” Channon, 629 N.W.2d at 863–64.
    Yet, we have indicated that “[c]hanges in duties or working
    conditions that cause no materially significant disadvantages to the
    employee are not adverse employment actions.” Id. at 862. Of course,
    the Channon formulation that an “adverse employment action” must be a
    “materially significant disadvantage,” id., is somewhat circular and not
    very helpful.        And, it is inconsistent with the Burlington Northern
    standard. In Channon, however, we concluded when the plaintiff offered
    evidence tending to show she faced ridicule, a constructive demotion,
    33Burlington  Northern makes it clear that the adverse action might not be
    employment related and thus the plaintiff in a retaliation case must show “adverse
    action” rather than “adverse employment action.” See 548 U.S. at 57, 126 S. Ct. at
    2408. Nonetheless, I will use the nomenclature used by our pre-Burlington Northern
    precedents.
    156
    and open hostility about her lawsuit, the record was sufficient to support
    a finding of adverse employment action. Id. at 866.
    The next pre-Burlington Northern Iowa retaliation case is Estate of
    Harris, 679 N.W2d 673.             In that case, the district court rather
    remarkably concluded that a punch to the chest delivered by a
    supervisor that ultimately killed the employee was not an “adverse
    employment action” sufficient to support a retaliation claim. Id. at 676.
    We reversed, noting it was for the jury to determine whether the action
    was simply an act of machismo or should be considered something more
    sinister. Id. at 679.
    In our analysis in Estate of Harris, we favorably cited a federal
    district court case for the proposition that moving an employee to an
    isolated corner might be sufficient to support a retaliation claim. Id. at
    678; see Harris v. Richards Mfg. Co., 
    511 F. Supp. 1193
    , 1203 (W.D.
    Tenn. 1981), aff’d in part and rev’d in part, 
    675 F.2d 811
     (6th Cir. 1982).
    We further cited Ray, 
    217 F.3d 1234
    , for the proposition that federal
    circuit courts were split on how               broadly to determine adverse
    employment action. 34 Estate of Harris, 679 N.W2d at 679. Nowhere in
    Estate of Harris, however, did we describe precisely what the appropriate
    standard was for determining an “adverse employment action” for
    purposes of a retaliation claim.
    34We also cited Farmland Foods for the proposition that materially adverse
    employment action embraces a wide variety of facts. 672 N.W.2d at 742. Farmland
    Foods involved a claim of a hostile environment, not a retaliation claim. Id. The
    substantive standard for establishing a hostile-environment claim is not the same as
    that for establishing a retaliation claim. For example, under Title VII, the focus on a
    hostile-environment claim is “terms and conditions of employment,” while the focus on
    a retaliation claim is whether the action might well reasonably deter an employee from
    pursuing a civil rights claim. Burlington Northern, 548 U.S. at 69, 126 S. Ct. at 2415–
    16. Yet, the application of both standards generally involve factual inquiries. See
    McElroy, 637 N.W.2d at 498–500.
    157
    Our last retaliatory discharge case is the pre-Burlington Northern
    case of Boyle, 
    710 N.W.2d 741
    . In Boyle, the district court found against
    the plaintiff on the underlying harassment claim and appeared to believe
    this resolution rendered the plaintiff’s alternative claim that she was
    discharged in retaliation for making her complaint moot. Id. at 750. We
    reversed.   Id. at 752.   In Boyle, however, we did not have occasion to
    explore the requirements of retaliatory discharge other than to emphasize
    that a retaliatory discharge claim did not depend upon the merits of the
    underlying complaint. Id.
    On balance, we should recognize that our pre-Burlington Northern
    adverse-employment-action cases did not have the benefit of Burlington
    Northern’s key insight that the test for material adverse action in the
    context of retaliation claim was whether a reasonable person would likely
    be deterred from utilizing complaint procedures, and not the familiar
    terms, conditions, and privileges of employment test that applies to
    disparate treatment cases.     See 548 U.S. at 73, 126 S. Ct. at 2417.
    Thus, cases like Channon embraced what federal law now recognizes is
    the wrong test.
    Although our cases reflect superseded federal law, they still
    generally recognized the subtlety of the workplace and the need to
    consider factual issues related to employment claims in light of the
    totality of facts and circumstances. See Channon, 629 N.W.2d at 862.
    Our cases further reflect the desirability of jury determinations of
    disputed factual issues in the retaliation context. See Estate of Harris,
    679 N.W.2d at 678.
    G. Discussion. At the outset, we are obliged to construe the ICRA
    broadly to effectuate its purposes.      Iowa Code § 216.18(1).   As has
    already been noted, maintaining clear channels for pursuing complaints
    158
    is critical to the regime established by the ICRA. Cf. Robinson, 519 U.S.
    at 346, 117 S. Ct. at 848 (stating purpose of retaliation provision to
    maintain “unfettered access to statutory remedial mechanisms”).
    The parties both accept the notion that we must determine what is
    a material adverse action for purposes of a retaliation claim under the
    ICRA.    I have little hesitance in embracing the approach of Burlington
    Northern, the EEOC, and the better reasoned caselaw that the test is
    whether a reasonable employer might be deterred from filing a complaint
    by the conduct in question. The purpose of a retaliation claim is to keep
    the access to the channels of civil rights law clear and open. The test for
    retaliation should be tied to its fundamental purpose.
    The test for material adverse action for purposes of retaliation is
    thus distinct from the test for an adverse employment action for
    purposes of a disparate-treatment claim.     As stated by the EEOC, the
    question of tangible harm goes to damages, not to liability, for retaliatory
    conduct. To the extent our prior cases suggest otherwise, they should be
    overruled.    I would thus specifically reject the approach of the mostly
    pre-Burlington Northern Eighth Circuit cases that indicate a material
    adverse action must include tangible employment action or must affect
    terms and conditions of employment.        See Scott Rosenberg & Jeffrey
    Lipman, Developing a Consistent Standard for Evaluating a Retaliation
    Case Under Federal and State Civil Rights Statutes and State Common
    Law Claims: An Iowa Model for the Nation, 53 Drake L. Rev. 359, 384–85
    (2005) (urging adoption of Ninth Circuit standard in Ray). As stated by
    the EEOC, in addition to the most obvious adverse actions such as
    denial of promotion, refusal to hire, denial of job benefits, demotion,
    suspension and discharge,
    159
    [o]ther types of adverse action may include work-related
    threats, warnings, reprimands, transfers, negative or lowered
    evaluations, transfers to less prestigious or desirable work or
    work locations, and any other types of adverse treatment
    that in the circumstances might well dissuade a reasonable
    person from engaging in protected activity.
    EEOC Enforcement Guidance II B.2.
    I would also agree with Burlington Northern, the EEOC, and the
    better reasoned caselaw that the determination of whether a plaintiff has
    introduced evidence sufficient to establish a material adverse action is
    fact specific and will, in most cases, generate a jury question. Of course,
    petty incidents in isolation do not suffice to show a materially adverse
    impact, but determining what is so petty that it would not deter a
    reasonable person from utilizing complaint procedures is usually best
    decided by a diverse jury with a mix of real world experience rather than
    by the court. Cf. Bell v. Johnson, 
    308 F.3d 594
    , 603–05 (6th Cir. 2002)
    (holding unless claimed retaliatory action is truly inconsequential, the
    plaintiff’s First Amendment claim should go to the jury); Gallagher v.
    Delaney, 
    139 F.3d 338
    , 342 (2d Cir. 1988) (noting that federal judges
    usually live “in a narrow segment of the enormously broad American
    socio-economic spectrum” and generally lack “the current real-life
    experience required in interpreting subtle sexual dynamics of the
    workplace,      based   on    nuances,     subtle    perception,   and    implicit
    communications”).
    We should embrace the notion that while each individual act might
    not   provide    sufficient   evidence    of   a   material   adverse   action,   a
    combination of relatively petty slights poses a different issue. Ordinarily,
    the cumulative weight of multiple or repetitive actions will generate a fact
    question for the jury to determine. Sanford, 327 F. App’x at 599; Vega,
    801 F.2d at 90; Ridley, 217 F. App’x at 135.
    160
    Finally, I would reject the laundry-list notion that various
    employment actions such as reprimands or negative job evaluations,
    transfers without loss of pay, or “snubbing” may be categorically
    regarded as never arising to the level of material adverse action. Take
    the negative job evaluation. In some setting, a negative job evaluation
    might not matter at all.         A negative job evaluation for an employee
    approaching retirement might produce a cynical grunt, but not much
    more. On the other hand, a negative job evaluation for an economically
    struggling head of household who is anxious to climb the work ladder to
    provide a better life for his or her family might reasonably feel quite
    different. 35 See, e.g., Walker v. Johnston, 
    798 F.3d 1085
    , 1095 (D.C. Cir.
    2015) (holding denial of deserved rise in performance rating may be
    actionable); Porter v. Shah, 
    606 F.3d 809
    , 817–18 (D.C. Cir. 2010)
    (stating interim performance of “borderline unacceptable” not materially
    adverse when delivered orally, no written record was made, and was
    superseded by end of the year review); see generally EEOC Manual 1998
    Update § 5.B.2 n.113.        This is precisely the kind of contextualization
    called for in Burlington Northern, which noted that a transfer to a night
    shift would be inconsequential for some, but not for others. 36 Of course,
    an insistence on contextualization is a two-way street.               It applies to
    plaintiffs as well as defendants.
    35In one study, ninety-five laws students at the University of Cincinnati were
    surveyed about what kind of job actions would dissuade them from filing a civil rights
    complaint. See Sperino, Retaliation, 
    67 Fla. L
    . Rev. at 2045. In the survey, eighty
    percent indicated that a negative evaluation either would or might dissuade them from
    pursuing a potential claim. Id.
    36Depending on the context, “snubbing” could easily be regarded by a factfinder
    as something that might well have dissuaded a reasonable worker from making or
    supporting a charge of discrimination. See B. Glenn George, Revenge, 83 Tul. L. Rev.
    439, 443 (2008).
    161
    In general, the first paragraph of the instruction accurately
    captures the test of material adverse action in the retaliation context. It
    emphasizes that material adverse action is action that is likely to deter a
    reasonable person from filing a complaint. That is the legal standard I
    would adopt under the ICRA.
    The second paragraph of the instruction, however, is problematic.
    It offers the unqualified statement that material adverse action includes
    a list of actions.   A reasonable jury could interpret the instruction to
    mean that if one of the listed actions is present, material adverse action
    is necessarily present as a matter of law, end of story. But, as stated
    above, the test is whether a reasonable person in the shoes of the
    plaintiff might well be deterred from pursuing a civil rights claim.       In
    considering this question, as Burlington Northern teaches us, “context
    matters.”    Id. at 69, 126 S. Ct. at 2416.    Though each of the listed
    actions, in context, separately or cumulatively, might rise to an “adverse
    material action” if it met the Burlington Northern test that it “might well
    deter” a reasonable person in the shoes of the plaintiff from engaging in
    protected activity, a jury is not compelled to make that finding as the
    trial court’s instruction might suggest. Id.
    Ordinarily, this instructional error would be prejudicial and require
    vacation of the verdict and remand for a new trial. Haskenhoff argues,
    however, that any error is cured by the jury’s verdict finding that
    Haskenhoff    was    constructively   discharged   by   HES.    Plainly,   a
    constructive discharge amounts to a material adverse action. 1 Andrew
    J. Ruzicho et al., Employment Practices Manual § 6B:7, Westlaw
    (database updated Mar. 2017) (“An actual or constructive discharge
    remains the clearest example of an adverse action.”).
    162
    But, as pointed out in Chief Justice Cady’s concurrence, there is a
    problem with Haskenhoff’s theory that the jury’s verdict on constructive
    discharge remedies any potential flaw in the instructions on retaliation.
    On questions number one and two, the jury answered in the affirmative
    that Haskenhoff proved her case of sexual harassment and retaliation
    respectively.     On question number three, the jury answered in the
    affirmative     the   question   of   whether   Haskenhoff   was   subject   to
    constructive discharge. In response to question number four, the jury
    returned a general damage verdict of $100,000 for lost wages and
    benefits, $300,000 for emotional distress, and $1,000,000 for the present
    value of emotional distress.
    While the jury did find a constructive discharge, it is not clear from
    the verdict form whether the jury’s constructive-discharge verdict was
    based upon the plaintiff’s claim of sexual harassment found in question
    one or whether it was based on the plaintiff’s claim of retaliation in
    question two. In order to cure the defect in the retaliation instruction,
    we must be able to conclude the jury found a causal relationship-
    protected activity giving rise to the retaliation claim and the constructive
    discharge.
    From the jury verdict form, however, it is possible the jury believed
    sexual harassment in question one, and not retaliation in question two,
    was causally related to the constructive discharge. If so, the jury could
    have awarded part of the general award damages in this case based upon
    the faulty retaliation instruction. See Farmers’ Nat’l Bank of Oskaloosa
    v. Stanton, 
    191 Iowa 433
    , 438–39, 182 N.W.647, 650 (1924). Further, we
    cannot say as a matter of law that Haskenhoff established a material
    adverse action which we have declared ordinarily involves a fact-based
    163
    determination.   As a result, I agree the judgment of the district court
    must be reversed and the matter remanded for a new trial.
    VI. Instructions Regarding Constructive Discharge.
    A. Overview of Constructive Discharge. The application of the
    constructive   discharge   doctrine    to   civil   rights   claims   has   been
    controversial. See Mark S. Kende, Deconstructing Constructive Discharge:
    The Misapplication of Constructive Discharge Standards in Employment
    Discrimination Remedies, 71 Notre Dame L. Rev. 39, 41–45 (1995)
    [hereinafter Kende] (“[B]y forcing discrimination victims to endure
    continuing discrimination, the constructive discharge approach [of a
    majority of federal courts] contravenes Title VII’s purposes.”).
    In this case, however, the parties do not contest whether the
    doctrine of constructive discharge applies but instead battle over the
    substantive contours of constructive discharge. In exploring constructive
    discharge, we recognized that while constructive discharge is generally a
    demanding doctrine, a too stringent constructive discharge test may
    simply be “a sophisticated means of providing undeserved protection to
    employers who discriminate.” Id. at 78.
    B. Challenged Instructions on Constructive Discharge.                 The
    jury was instructed on constructive discharge as follows: “The employer
    need not really want the employee to quit. . . . The employee must show
    that she was subjected to sexual harassment or retaliation which made
    her believe there was no chance for fair treatment at Homeland.”
    HES had sought to instruct the jury that Haskenhoff had to show
    “the Defendant acted with the intent of forcing the Plaintiff to quit, or the
    Plaintiff’s resignation was a reasonably foreseeable result of the
    Defendant’s actions.” Additionally, HES sought to instruct the jury as
    follows:
    164
    An employee cannot “quit and sue” and then claim to
    have been constructively discharged. Rather, the conditions
    giving rise to the resignation must be sufficiently
    extraordinary and egregious to overcome the normal
    motivation of a competent, diligent and reasonable employee
    to remain on the job to earn a livelihood and to serve his or
    her employer.      In order to amount to a constructive
    discharge, adverse working conditions must be unusually
    “aggravated” or amount to a “continuous pattern” before the
    situation will be deemed intolerable. Generally speaking, a
    single, trivial or isolate act is insufficient to support a
    constructive discharge claim. Finally, conditions cannot be
    considered intolerable unless the employer has been given a
    reasonable chance to resolve the problem.
    C. Positions of the Parties.
    1. HES. HES asserts the constructive discharge instruction was
    erroneous because of the assertion that the employer “need not really
    want the employee to quit.”        Further, HES claims the instruction
    improperly injected the subjective views of Haskenkoff into the issue.
    Further, HES, citing Van Meter Industrial v. Mason City Human Rights
    Commission, 
    675 N.W.2d 503
    , 511 (Iowa 2004), argues the district court
    erred in failing to instruct that “conditions will not be considered
    intolerable unless the employer has been given a reasonable chance to
    resolve the problem.” Finally, in a footnote, HES challenges the repeated
    reference to “fairness” in the instruction.
    2. Haskenhoff. With respect to the instruction regarding the fact
    that “the employer need not really want the employee to quit,”
    Haskenhoff argues that this language is supported by Van Meter, 675
    N.W.2d at 512. While the instruction did refer to fairness, Haskenhoff
    states the Van Meter case repeatedly referred to the concept of fair
    treatment. Id. at 511–12.
    With respect to the question of whether the instruction was
    erroneous because of reference to her subjective feelings, Haskenhoff
    notes the instructions, taken as a whole, repeatedly referred to the
    165
    objective standard for constructive discharge. According to Haskenhoff,
    Instruction Nos. 33 and 34 dealing with constructive discharge contained
    no less than seven references to the reasonableness standard.
    Haskenhoff also asserts that HES’s proposed instruction that
    “conditions will not be considered intolerable unless the employer has
    been given a reasonable chance to resolve the problem” was presented in
    the instructions.   Haskenhoff notes the instructions stated that the
    “conditions . . . must be sufficiently extraordinary and egregious” that
    “adverse working conditions must be unusually ‘aggravated’ or amount
    to a ‘continuous pattern’ before the situation will be deemed intolerable,”
    and “a single, trivial, or isolated act is insufficient to support a
    constructive discharge claim.” In any event, Haskenhoff suggests that in
    light of the evidence the jury would not have found that the employer did
    not have a reasonable chance to resolve the issue under the evidence
    adduced at trial.
    D. Federal Caselaw on Constructive Discharge.
    1. Introduction. When applying the law of constructive discharge,
    it appears almost universally accepted that the test of whether there is a
    constructive discharge is whether working conditions are sufficiently
    intolerable that a reasonable person in the position of the employee
    would have felt compelled to resign. See 2 Christopher Bello, Litigating
    Wrongful Discharge Claims § 7.62 n.3, at 7–260 (2013–2014 Cumulative
    Supp.) (collecting cases).   The reasonable-person test is generally an
    objective test, but it is qualified by the notion that the reasonable person
    must be one “in the position of the employee.” Id.
    2. Intent to create hostile environment.    The federal cases under
    Title VII are split on the question of whether a plaintiff in a constructive
    discharge case must prove employer intent.       The majority view is that
    166
    constructive discharge occurs even if the employer did not intend to
    create the intolerable working conditions.      See, e.g., Ramsey v. City &
    Cty. of Denver, 
    907 F.2d 1004
    , 1010 (10th Cir. 1990); Watson v.
    Nationwide Ins., 
    823 F.2d 360
    , 361 (9th Cir. 1987); Alicea Rosado v.
    Garcia Santiago, 
    562 F.2d 114
    , 119 (lst Cir. 1977). On the other hand,
    some cases hold that employer intent must be proved. See, e.g., Martin
    v. Cavalier Hotel Corp., 
    48 F.3d 1343
    , 1354 (4th Cir. 1995); Yates v. Avco
    Corp., 
    819 F.2d 630
    , 636 (6th Cir. 1987); Junior v. Texaco, Inc., 
    688 F.2d 377
    , 379 (5th Cir. 1982).
    3. Reasonable chance to work out the problem. The Eighth Circuit
    has stated that an employee who quits without giving his or her employer
    a reasonable chance to work out a problem is not constructively
    discharged. Trierweiler v. Wells Fargo Bank, 
    639 F.3d 456
    , 460 (8th Cir.
    2011); Vajdl v. Mesabi Acad. of KidsPeace, Inc., 
    484 F.3d 546
    , 553 (8th
    Cir. 2007).   A similar approach has been embraced by the Fifth and
    Eleventh Circuits. Kilgore v. Thompson & Brook Mgt., Inc., 
    93 F.3d 752
    ,
    754 (11th Cir. 1996); Bozé v. Branstetter, 
    912 F.2d 801
    , 805 (5th Cir.
    1990).
    In Suders v. Easton, the Third Circuit held it was relevant whether
    the employee explored alternative avenues to resolve the alleged
    discrimination before resigning, but that “a failure to do so will not defeat
    a claim of constructive discharge.”        
    325 F.3d 432
    , 445–46 (3rd Cir.
    2003), vacated on other grounds sub nom Pa. State Police v. Suders, 
    542 U.S. 129
    , 
    124 S. Ct. 2343
     (2004). Other federal circuits have found that
    the failure to attempt to resolve the problem prior to quitting as only a
    factor to be considered by the fact finder in determining whether a
    constructive discharge is present.    Lindale v. Tokheim Corp., 
    145 F.3d 953
    , 956 (7th Cir. 1998); Levendos v. Stern Entm’t, Inc., 
    909 F.2d 747
    ,
    167
    753 (3d Cir. 1991).    A case out of the First Circuit took yet another
    position, indicating that staying on the job while seeking redress is
    required except in exceptional cases, Lee-Crespo v. Schering-Plough Del
    Caribe Inc., 
    354 F.3d 34
    , 35 (1st Cir. 2003). One court found such an
    exceptional case when an employee correctly believed her termination
    was imminent. EEOC v. Univ. of Chi. Hosps., 
    276 F.3d 326
    , 331–32 (7th
    Cir. 2002).
    One federal court noted the potential tightrope that a plaintiff must
    show in proving a constructive discharge claim.       In Bristow v. Daily
    Press, Inc., the Fourth Circuit noted that while an employee must show
    his working conditions are intolerable, his “desire for reinstatement to
    his position belies the claim that intolerable conditions underlay his
    resignation.” 
    770 F.2d 1251
    , 1256 (4th Cir. 1975). It is surely true that
    a   requirement   an   employee   remain   employed    in   an   intolerable
    employment environment is a concept in tension with itself.
    E. State Caselaw on Constructive Discharge. A number of state
    courts have expressly considered whether an employer must have a
    reasonable chance to remedy the situation before a finder of fact may
    find that an employee was constructively discharged.        In Pollock, the
    court held there was no legal requirement that an employee must
    complain of harassment and wait and see what happens in all
    circumstances.    11 S.W.3d at 761.    The Pollock court reasoned that a
    failure to complain may show the employee was not constructively
    discharged, but not in all cases. Id. at 765. In some cases, according to
    the court, a failure to complain may indicate that other factors were at
    play other than the tolerability of the working conditions. Id. The court
    concluded that courts must consider the totality of the circumstances in
    determining whether working conditions were, in fact, intolerable.       Id.
    168
    Later Missouri appellate court cases, however, seemed to abandon the
    Pollock approach in favor of a reasonable-chance-to-resolve requirement.
    See DeWalt v. Davidson Serv./Air, Inc., 
    398 S.W.3d 491
    , 501 (Mo. Ct.
    App. 2013); Gamber v. Mo. Dep’t of Health & Senior Servs., 
    225 S.W.3d 470
    , 475 (Mo. Ct. App. 2010). Other state courts, however, have followed
    the general approach in Pollock.      See, e.g., Charles v. Regents of N.M.
    State Univ., 
    256 P.3d 29
    , 34–35 (N.M. Ct. App. 2010); Ballinger v.
    Klamath Pacific Corp., 
    898 P.2d 232
    , 238 (Or. Ct. App. 1995); see also
    Binkley v City of Tacoma, 
    787 P.2d 1366
    , 1376 (Wash 1990).
    A final case of interest is Marten Transportation, Ltd. v. Department
    of Industry, Labor, & Human Relations, 
    491 N.W.2d 96
     (Wis. Ct. App.
    1992), rev’d, 
    501 N.W.2d 391
     (Wis. 1993).        The Wisconsin court, in a
    case noted by commentators, declared that “requiring a discrimination
    victim to stay put to mitigate damages [is] like requiring ‘victims’ of legal
    malpractice to continue being serviced by their negligent lawyer in order
    to give the lawyer the chance to improve his or her skills.” Id. at 199; see
    Arthur Young & Co. v. Sutherland, 
    631 A.2d 354
    , 362 (D.C. 1993)
    (explaining that when working conditions are intolerable, an employee
    need not remain in them and attempt to resolve them in order to recover
    for constructive discharge); see also Kende, 71 Notre Dame L. Rev. at 53
    n.78.    The Marten Transportation case, however, was overruled by the
    Wisconsin Supreme Court in a divided opinion. Marten Transp., Ltd. v.
    Dep’t of Indus., Labor, & Human Relations, 
    501 N.W.2d 391
    , 399 (Wis.
    1993).
    F. Iowa Caselaw on Constructive Discharge. In the pre-Suders
    case of Van Meter Industrial, we considered constructive discharge under
    a local human rights ordinance. 675 N.W.2d at 505. We presented a
    basic outline of the legal parameters of a constructive discharge claim,
    169
    which appear to have been uncontested. Id. at 510–12. Citing an Eighth
    Circuit case, we stated that “conditions will not be considered intolerable
    unless the employer has been given a reasonable chance to resolve the
    problem.” Id. at 511.     But we balanced this observation with the
    contrapuntal declaration in the next sentence, stating, “On the other
    hand, an employee need not stay if he or she reasonably believes there is
    no possibility the employer will respond fairly.” Id. Thus, Van Meter is
    ambiguous on the question of whether an employee suffering intolerable
    discrimination must remain on the job while the employer investigates.
    In any event, Van Meter is not entitled to stare decisis because the
    parties agreed on the elements of constructive discharge in their briefs
    before the court. See, e.g., Hemingway, 734 F.3d at 335 (holding a prior
    case was not precedent on an issue when the issue was not contested);
    Goldberger, 209 F.3d at 49 (finding certain cases did not support an
    issue when the issue was not contested by the parties nor addressed by
    the panel); Fulton Found., 108 N.W.2d at 316–17 (stating a case was not
    efficacious on an issue which was not challenged by the parties). In any
    event, it remains to be seen whether this conclusion remains good Iowa
    law after law Suders.
    G. Discussion.
    1. No requirement of wanting employee to quit. As seen above, the
    caselaw is divided on the question of whether an employer must desire
    the employee to quit before a plaintiff may prove constructive discharge.
    I agree with the majority approach, however, that there is no such
    subjective legal requirement. I do so for several reasons. The focus on
    constructive discharge should be on the perceptions of a reasonable
    employee in light of the remedial purposes of the ICRA. I do not think
    subjective protestations on the part of the employer should be a defense
    170
    if the objective evidence demonstrates working conditions would be
    considered intolerable by a reasonable person in the shoes of the
    plaintiff.   See Ramsey, 907 F.2d at 1010; Watson, 823 F.2d at 361;
    Alicea Rosado, 562 F.2d at 119.
    2. Objective test. In Van Meter, 675 N.W.2d at 511, we stated that
    the standard was objective and most courts, including the United States
    Supreme Court in Suders, have made similar statements. 542 U.S. at
    141, 124 S. Ct. at 2351.      And, no party here contests the objective
    nature of a constructive discharge claim.
    Therefore, the suggestion in the instruction that constructive
    discharge may be shown if the employee subjectively believes conditions
    are intolerable is not in accord with the law as agreed upon by the
    parties in this case. Although the instruction was imperfect, taken as a
    whole, any error was harmless on this point in light of the repeated
    reference to reasonability throughout the instructions.         On retrial,
    however, the district court might want to eliminate any confusion by
    consistently referencing the objective nature of the inquiry.
    3. Reasonable chance to resolve the problem: Can Faragher-Ellerth
    jump the track (again)? The last issue is the district court’s refusal to
    instruct that the “conditions will not be considered intolerable unless the
    employer has been given a reasonable chance to resolve the problem.” At
    its core, this is another effort to transplant the thrust of the Farragher-
    Ellerth affirmative defense outside the context of vicarious liability. See
    Sara Kagay, Applying the Ellerth Defense to Constructive Discharge: An
    Affirmative Answer, 
    85 Iowa L
    . Rev. 1035, 1050–51 (2000).             This
    approach appears to have been embraced by the Eighth and Eleventh
    Circuits, but not in the Seventh Circuit. Trierweiler, 639 F.3d at 460;
    Lindale, 145 F.3d at 956; Bozé, 912 F.2d at 805. As seen above, there is
    171
    state caselaw from Missouri, New Mexico, and Oregon to the contrary.
    Pollock, 11 S.W.3d at 761, Charles, 256 P.3d at 34–35; Ballinger, 898
    P.2d at 238.      The caselaw thus presents us with an important
    interpretive choice.
    Based on our review of the possible approaches, I think the better
    view is not to impose a legal requirement that an employee must give the
    employer a reasonable period of time to remedy the problem in all
    constructive discharge cases. As pointed out in the caselaw and in the
    commentary, this requirement is a Catch-22 in that the plaintiff must
    prove conditions are so intolerable that any reasonable person would
    quit, while remaining patiently in the workplace to see if an employer can
    change its behavior and come up with a remedy. See Gormley v. Coca-
    Cola Enters., 
    109 P.3d 280
    , 285 (N.M. 2005) (finding fact that employee
    gave employer one-month notice before quitting a factor in the employer’s
    favor in considering summary judgment on constructive discharge
    claim). In addition, requiring a plaintiff to remain in a situation that is
    objectively intolerable based upon the employer’s discriminatory conduct
    has a cynical if not brutal quality. There seems little point to require an
    employee to stay and fight when the employment relationship has been
    seriously damaged by discriminatory conduct of the employer. Martha
    Chamallas, Title VII’s Midlife Crisis: The Case for Constructive Discharge,
    77 S. Cal. L. Rev. 307, 372 (2004) [hereinafter Chamallas].
    Empirical sources confirm that very few victims of sexual
    harassment pursue complaints through internal grievance procedures.
    Although now somewhat dated, scholarly literature suggests that
    workers who suffer harassment who utilize internal channels range from
    2.5%–12%. See Chamallas, 77 S. Cal. L. Rev. at 373. Remarkably, even
    among persons who ultimately sued their employer for workplace
    172
    harassment, nearly half did not report the harassment and only fifteen
    percent did so in a timely manner. Id. The question thus arises as to
    whether   a   court   evaluating    reasonable   employee   behavior    in   a
    constructive discharge context should require atypical behavior. See id.
    And, courts should be cautious in assuming as a matter of law that an
    assertive approach which judges on an appellate bench with relative job
    security might think reasonable might not be regarded as reasonable by
    a jury of lay persons with wide experience in a diverse labor market.
    Finally, forcing persons into internal processes tends to privatize
    civil rights enforcement in an environment where sexual harassment may
    be considered to be a personal problem for individual women rather than
    a systemic issue.     Id.    Internal complaint procedures are thus often
    unappealing because of a lack of empathy from decision-makers and the
    perceived risks of retaliation. The end result may be for victims to simply
    suffer in silence and then quit when conditions get bad. Id. at 379.
    I would thus conclude there is no legal requirement to prevail on a
    hostile environment claim that an employer had an opportunity to
    resolve the problem. Pollock, 11 S.W.3d at 761; Charles, 256 P.3d at 37;
    Ballinger, 898 P.2d at 238.       That said, the failure of an employee to
    pursue available remedies with the employer may be evidence for the fact
    finder to consider in determining whether a work environment was truly
    so intolerable as to satisfy the requirements of a constructive discharge.
    See Lindale, 145 F.3d at 955–56; Levendos, 909 F.2d at 1230. It is not,
    however, dispositive.       Whether conditions were so intolerable that a
    reasonable person would have no choice but to leave employment is “a
    heavily fact-driven determination.” Levendos, 909 F.2d at 1230. As a
    result, the constructive discharge instruction was not flawed because of
    its failure to require as a matter of law that the plaintiff remain in the
    173
    intolerably hostile workplace to allow the employer to attempt to remedy
    the problem.
    VII. Conclusion.
    For the above reasons, I would generally conclude the approach of
    the district court comported with Iowa law except with respect to the
    instruction regarding materially adverse conditions required to support
    retaliation.   For this reason, I too would reverse the judgment of the
    district court and remand for a new trial.

    in part. Cady, C.J., joins in part.
