  • Affirmed in Part, Reversed and Remanded in Part, and Opinion filed January
    4, 2017.
    In The
    Fourteenth Court of Appeals
    NO. 14-15-00124-CV
    ROSEMARY TOOKER, Appellant
    V.
    ALIEF INDEPENDENT SCHOOL DISTRICT, Appellee
    On Appeal from the 127th District Court
    Harris County, Texas
    Trial Court Cause No. 2013-06192
    OPINION
    This appeal arises out of employment-discrimination claims. An employee
    filed suit against her employer, an independent school district, asserting claims
    based on the employer’s alleged violations of the Texas Commission on Human
    Rights Act, the Fair Labor Standards Act, the Family and Medical Leave Act, and
    the Texas Whistleblower Act. The trial court granted the employer’s pleas to the
    jurisdiction and summary-judgment motions and dismissed all of the employee’s
    claims. We reverse the trial court’s judgment as to a retaliation claim under the
    Fair Labor Standards Act and affirm the remainder of the judgment.
    I.     FACTUAL AND PROCEDURAL BACKGROUND
    Appellant/plaintiff Rosemary Tooker started working for appellee/defendant
    Alief Independent School District (the “District”) in 1986. At all times material to
    Tooker’s claims she was working for the District as an Energy Manager Assistant
    in the District’s Maintenance Department.        Tooker obtained a Class A Air
    Conditioning and Refrigeration Contractor License. Upon the retirement of the
    employee whose Class A Air Conditioning and Refrigeration Contractor License
    the District was using, Tooker offered the District the use of her Class A License.
    According to Tooker, in March 2011, the District offered to pay her $400 per
    month for the use of her License, even though the District had been paying the
    retired male employee $800 per month for the use of the same type of license.
    Tooker asserted that she lodged an internal complaint of gender discrimination
    with the District based on the District’s refusal to pay her $800 per month for the
    use of the Class A License. Tooker alleged that after she made this complaint, the
    District began harassing her “on almost a daily basis.” In July 2011, Tooker filed a
    charge alleging gender discrimination and retaliation (hereinafter the “First
    Charge”). She claimed the District retaliated against her because she had appealed
    the District’s decision to offer her only $400 per month for the use of her License.
    In April 2011, Tooker witnessed an incident that she believed may have
    been theft of the District’s property by her supervisor and a coworker. Tooker
    alleges that she promptly reported the incident to the District’s police department
    for investigation. Tooker claims that the police department took no action and that
    nearly two years later (in January 2013), she was told that the police department
    never received her incident report. The same month, Tooker met with
    2
    representatives from the District’s human resources department and mentioned that
    the police department had not investigated the 2011 theft incident. According to
    Tooker, soon after that meeting the human resources department contacted the
    police department to begin the investigation.          Tooker alleges that almost
    immediately thereafter several Department employees began making false
    allegations against Tooker in an effort to further harass her, force her to quit, and
    diminish the impact of her incident report and lawsuit that would soon follow. In
    January 2013, the District suspended Tooker with pay pending an investigation of
    allegations that Tooker had created a hostile work environment. Tooker filed a
    second charge of discrimination, alleging that the District was paying her less than
    males who perform the same or similar job duties and asserting continued
    retaliation and gender discrimination (hereinafter the “Second Charge”).
    Tooker also alleges that the District denied her compensatory time and
    refused to compensate her at time-and-a-half for all of her overtime hours.
    At the end of January 2013, Tooker filed suit against the District, eventually
    asserting claims based on the District’s alleged violations of the Texas
    Commission on Human Rights Act, Chapter 21 of the Texas Labor Code (the
    “Human Rights Act”), the Fair Labor Standards Act, title 29, chapter 8 of the
    United States Code (the “Fair Labor Act”), the Family and Medical Leave Act, title
    29, chapter 28 of the United States Code (the “Leave Act”), and the Texas
    Whistleblower Act, chapter 554 of the Texas Government Code (the
    “Whistleblower Act”). See 29 U.S.C. § 201, et seq. (West, Westlaw through 2015
    R.S.); 29 U.S.C. § 2611, et seq. (West, Westlaw through 2015 R.S.); Tex. Lab.
    Code Ann. § 21.001, et seq. (West, Westlaw through 2015 R.S.); Tex. Gov’t Code
    Ann. § 554.001, et seq. (West, Westlaw through 2015 R.S.).
    In May 2013, the District filed a plea to the jurisdiction, which the trial court
    3
    granted as to Tooker’s Human Rights Act claims.1 The trial court later rendered a
    final judgment when it granted pleas to the jurisdiction and summary-judgment
    motions filed by the District on July 7, 2014 and on July 28, 2014.2 Tooker
    perfected appeal from the trial court’s final judgment.
    II.    ISSUES AND ANALYSIS
    A. Did the trial court err in dismissing the gender-discrimination claim
    based on the stipend for the license?
    Tooker asserted a gender-discrimination claim against the District alleging
    that the District offered to pay her $400 per month for the use of her License, even
    though the District had been paying a male employee $800 per month for the use
    of the same type of license. The trial court granted the District’s plea to the
    jurisdiction and dismissed this claim for lack of jurisdiction. In her first argument
    on appeal Tooker asserts that the trial court erred in granting the District’s plea as
    to this claim.
    Sovereign immunity deprives a trial court of jurisdiction over lawsuits in
    which a party sues a school district unless the school district’s sovereign immunity
    has been waived. See Mission Consol. Indep. Sch. Dist v. Garcia, 
    372 S.W.3d 629
    ,
    636 (Tex. 2012). The Human Rights Act clearly and unambiguously waives
    immunity for suits brought against school districts under this statute. See Tex.
    Lab. Code Ann. §§ 21.002(4), 21.002(8)(D), 21.051, 21.254 (West, Westlaw
    through 2015 R.S.); 
    Garcia, 372 S.W.3d at 636
    . But, the Legislature has waived
    immunity only for those suits in which the plaintiff actually alleges a violation of
    the Human Rights Act by pleading facts that state a claim thereunder. See Tex.
    1
    In August of 2014, while this suit was pending in the trial court, the District terminated
    Tooker’s employment, but no claims by Tooker regarding this termination are part of this suit.
    2
    The second document bears a “July 29, 2014” file stamp, but the trial court signed an order
    deeming this document to have been filed on July 28, 2014.
    4
    Lab. Code Ann. §§ 21.002(4), 21.002(8)(D), 21.051, 21.254; 
    Garcia, 372 S.W.3d at 636
    –37.
    For a plaintiff who proceeds under the McDonnell Douglas burden-shifting
    framework, the prima facie case is the necessary first step to bringing a
    discrimination claim under the Human Rights Act. See 
    Garcia, 372 S.W.3d at 637
    . While such a plaintiff must sufficiently plead the prima facie case of her
    statutory claim, she will be required to submit evidence only if the defendant
    presents evidence negating one of those basic facts. See 
    id. In this
    situation,
    failure to raise a fact issue on a challenged element of the prima facie case means
    that the trial court has no jurisdiction and the claim should be dismissed. See 
    id. In the
    absence of direct evidence of discrimination, the elements of Tooker’s
    prima facie case of gender discrimination under the McDonnell Douglas
    framework are that Tooker (1) is a member of a protected class, (2) was qualified
    for her position, (3) was subject to an adverse employment decision, and (4) was
    treated less favorably than similarly situated persons not in the protected class. See
    College of the Mainland v. Glover, 
    436 S.W.3d 384
    , 393 (Tex. App.—Houston
    [14th Dist.] 2014, pet. denied). In its first plea to the jurisdiction, the School
    District challenged the third and fourth elements. The trial court impliedly granted
    the plea to the jurisdiction on all bases asserted by the School District.
    In filing a plea to the jurisdiction, the School District challenged the trial
    court’s subject-matter jurisdiction. Bland Indep. Sch. Dist. v. Blue, 
    34 S.W.3d 547
    ,
    554 (Tex. 2000). Because subject-matter jurisdiction is a question of law, we
    conduct a de novo review of the trial court’s granting of the plea. Tex. Dep’t of
    Parks & Wildlife v. Miranda, 
    133 S.W.3d 217
    , 226 (Tex. 2004). In its plea to the
    jurisdiction, the School District challenged the existence of jurisdictional facts;
    therefore, we consider relevant evidence submitted by the parties when necessary
    5
    to resolve the jurisdictional issues raised, as the trial court is required to do. See 
    id. If the
    evidence creates a fact question regarding the jurisdictional issue, then the
    plea to the jurisdiction must be denied. See 
    id. at 227–28.
    But, if the relevant
    evidence is undisputed or fails to raise a fact question on the jurisdictional issue,
    then the court rules on the plea to the jurisdiction as a matter of law. 
    Id. at 228.
    The District challenged the prima facie element that Tooker was treated less
    favorably than similarly situated males regarding payment of a stipend for use of a
    Class A Air Conditioning and Refrigeration Contractor License. See College of the
    
    Mainland, 436 S.W.3d at 393
    . The Supreme Court of Texas has concluded that
    “[e]mployees are similarly situated if their circumstances are comparable in all
    material respects.” Ysleta Indep. Sch. Dist. v. Monarrez, 
    177 S.W.3d 915
    , 917
    (Tex. 2005) (per curiam). The United States Court of Appeals for the Fifth Circuit
    has articulated a similar standard, saying that employees are similarly situated if
    their circumstances are “nearly identical.” See Perez v. Tex. Dep’t of Criminal
    Justice, Institutional Div., 
    395 F.3d 206
    , 213 (5th Cir.2004).
    The District submitted with its first plea to the jurisdiction affidavits of Jeff
    DeLisle and Charles Woods. DeLisle, the Director of the District’s Maintenance
    and Operations Department, testified that he supervised Tooker and all of the
    District’s Maintenance Department employees.3 According to DeLisle, in March
    2011, John Proffitt retired. Proffitt had been working as the HVAC Foreman.
    During the 2010-2011 school year, Proffitt received an $800 per month stipend for
    the “Use of License.” Proffitt held three licenses that accounted for the total
    amount of the stipend:       (1) a “Class A Air Conditioning and Refrigeration
    Contractor License,” (2) an “EPA 608 Certification-Universal License,” and (3) a
    3
    This paragraph and the following four paragraphs describe relevant portions of DeLisle’s
    testimony.
    6
    “3rd Grade Stationary Engineer License” (hereinafter “Boiler Operator License”).
    DeLisle determined that no other employee in the HVAC Department held
    all three licenses that Proffitt held. One employee had the EPA certification, and
    another employee had the Boiler Operator License, and each employee was willing
    to dedicate his license or certification for the District’s use. DeLisle testified that
    he and Wilton Curry, the Maintenance Department Supervisor, determined what
    they believed to be a fair value for each of the three licenses and divided the $800
    per month stipend that Proffitt had been receiving for the use of the three licenses
    according to the values they established, which were $400 per month for the Class
    A License, $200 per month for the EPA license, and $200 per month for the Boiler
    Operator License. Stanley Kuykendall, a male employee, began receiving a $200
    per month stipend for the use of his EPA license, and Robert Pritchard, another
    male employee, began receiving a $200 per month stipend for the use of his Boiler
    Operator License. Curry and DeLisle agreed that the Class A License should have
    a higher value than the other two licenses because it is more difficult to obtain and
    permits the licensee to perform a wide variety of services on HVAC systems.
    The District offered Tooker a $400 per month stipend for the use of her
    License, which is a Class A Air Conditioning and Refrigeration Contractor
    License.   Tooker refused to accept the $400 per month stipend and instead
    demanded the full $800 per month stipend that Proffitt had received in
    consideration of the use of all three of his licenses. DeLisle testified that the
    District could not have offered Tooker the $800 per month stipend that Proffitt
    formerly received because she did not hold the same licenses and she was not
    qualified to perform the full range of duties assigned to Proffitt while Proffitt
    served as the HVAC Forman. According to DeLisle, Tooker’s job duties as the
    Energy Manager Assistant differed from Proffitt’s duties as the HVAC Foreman.
    7
    As the Energy Manager Assistant, Tooker operated mostly in a clerical role.
    Her job goal was to assist in the coordination of energy management programs for
    the District’s campuses. Tooker received requests for maintenance to the District’s
    air conditioning systems and input those requests into an automatic scheduler.
    Tooker also received phone calls regarding the hot or cold conditions at the
    District’s campuses and remotely verified those conditions using the energy
    management system. Tooker also could dispatch technicians to investigate any
    suspected issues with the District’s HVAC systems. Tooker’s job description did
    not require her to travel to the District’s campuses to troubleshoot any HVAC
    equipment or to make any repairs to HVAC equipment.
    Proffitt supervised all of the District’s HVAC technicians, and ultimately
    was responsible for troubleshooting, repairing, maintaining, and installing HVAC
    equipment. Proffitt also was responsible for disciplining HVAC staff, conducting
    employee trainings, and for other human resources functions related to HVAC
    staff, such as granting leave and reviewing time cards and work orders. Proffitt
    also was charged with completing material and parts requisitions and with
    receiving bids on goods and services from outside contractors.
    Charles Woods, the Deputy Superintendent of Business Services for the
    District, testified that in the spring of 2011, DeLisle and Curry informed Woods
    that they had denied Tooker’s request for an $800 per month stipend for the
    District’s use of Tooker’s HVAC license.4 According to Woods, DeLisle informed
    Woods that Tooker demanded that amount based on her mistaken belief that
    Proffitt received an $800 per month stipend for the use of his HVAC license.
    Woods stated that Proffitt actually received the $800 per month stipend because he
    4
    This paragraph describes relevant portions of Woods’s testimony.
    8
    held three licenses, two of which Tooker did not possess. Woods affirmed the
    decision to offer Tooker a $400 per month stipend.
    The evidence attached to the District’s first plea to the jurisdiction negated
    the prima facie element that Tooker was treated less favorably than similarly
    situated males regarding payment of a stipend for use of a Class A Air
    Conditioning and Refrigeration Contractor License. See College of the 
    Mainland, 436 S.W.3d at 393
    –95.       Therefore, to avoid dismissal Tooker had to submit
    evidence raising a fact issue as to this essential element. See 
    Garcia, 372 S.W.3d at 637
    . The only evidence that Tooker filed in response to the first jurisdictional
    plea was a copy of the Second Charge. That charge does not raise a fact issue as to
    whether Tooker was treated less favorably than similarly situated males regarding
    payment of a stipend for use of a Class A Air Conditioning and Refrigeration
    Contractor License. See 
    id. On appeal,
    Tooker suggests that Proffitt received the $800 per month stipend
    solely for the use of Proffitt’s Class A Air Conditioning and Refrigeration
    Contractor License. Tooker also asserts that DeLisle misrepresented the facts in
    his affidavit attached to the first jurisdictional plea. According to Tooker, Proffitt
    did not obtain an $800 per month stipend based on his having three licenses, and
    Proffitt was receiving an $800 per month stipend before he obtained the EPA
    license and the Boiler Operator License. Tooker also makes other assertions. The
    primary evidence upon which Tooker relies as allegedly raising a fact issue is
    Tooker’s declaration that was attached to her “Motion to Reconsider Granting
    Defendant’s Plea to the Jurisdiction.” But, the trial court denied this motion as to
    Tooker’s claims under the Human Rights Act in an order in which the court did not
    say that the court had considered the evidence attached to Tooker’s motion to
    reconsider. Tooker does not argue that the evidence in this declaration was newly
    9
    discovered and could not have been discovered through due diligence before the
    trial court granted the first jurisdictional plea. Though Tooker attached the
    declaration to her motion to reconsider, the record does not show that the trial court
    considered this declaration in granting the first jurisdictional plea and dismissing
    Tooker’s claims under the Human Rights Act, nor does the record show that the
    trial court exercised its discretion to consider the untimely declaration as
    potentially raising a fact issue in connection with ruling on Tooker’s motion to
    reconsider.       In this context, we cannot consider the declaration as potentially
    raising a fact issue as to the grounds raised in the District’s first jurisdictional plea.
    See Guishard v. Money Mgmt. Intern., Inc., No. 14-14-000362-CV, 
    2015 WL 4984853
    , at *2 (Tex. App.—Houston [14th Dist.] Aug. 20, 2015, no pet.) (mem.
    op.); Smith v. City of League City, 
    338 S.W.3d 114
    , 123 n.6 (Tex. App.—Houston
    [14th Dist.] 2011, no pet.); McMahan v. Greenwood, 
    108 S.W.3d 467
    , 499–500
    (Tex. App.—Houston [14th Dist.] 2003, pet. denied).
    In response to the District’s first jurisdictional plea Tooker did not timely
    submit evidence raising a fact issue as to whether Tooker was treated less
    favorably than similarly situated males regarding payment of a stipend for use of a
    Class A Air Conditioning and Refrigeration Contractor License. See 
    Garcia, 372 S.W.3d at 637
    . Tooker has not shown that an exception applies under which this
    court can consider the declaration attached to her motion to reconsider in
    determining whether the evidence raised a fact issue on this point. See Guishard,
    
    2015 WL 4984853
    , at *2; 
    Smith, 338 S.W.3d at 123
    n.6; 
    McMahan, 108 S.W.3d at 499
    –500. We conclude that the trial court did not err in granting District’s first
    plea to the jurisdiction as to Tooker’s gender-discrimination claim regarding
    compensation for Tooker’s License.5 See College of the 
    Mainland, 436 S.W.3d at 5
        Tooker asserts that if we find the allegations in her pleading defective, we should reverse and
    10
    393–95.
    B. Has appellant sufficiently briefed a challenge to the trial court’s
    dismissal of her retaliation claim based on the District’s 2011 conduct?
    In two paragraphs in her appellate brief, Tooker states that the trial court had
    jurisdiction over her retaliation claim under the Human Rights Act based on the
    District’s conduct in 2011. Tooker asserts that the District substantially reduced or
    changed her job duties after her 2011 gender-discrimination complaint. Though
    Tooker cites three documents (two of which were not before the trial court when it
    granted the District’s first jurisdictional plea), she does not cite any legal
    authorities, nor does she discuss the grounds the District asserted in the first
    jurisdictional plea against this claim. Tooker has not provided any analysis or
    legal citations showing how the trial court erred in granting the District’s first plea
    to the jurisdiction as to this claim. Even liberally interpreting Tooker’s appellate
    briefing, we cannot conclude that she has adequately briefed this issue. See Tex.
    R. App. P. 38.1(i); Kaldis v. Aurora Loan Servs., 
    424 S.W.3d 729
    , 736–37 (Tex.
    App.—Houston [14th Dist.] 2014, no pet.). Therefore, Tooker has waived any
    challenge to the trial court’s granting of the District’s first jurisdictional plea as to
    the retaliation claim based on the District’s conduct in 2011. See 
    Kaldis, 424 S.W.3d at 736
    –37.
    C. Has appellant sufficiently briefed a challenge to the trial court’s
    dismissal of her retaliation claims based on other conduct?
    In her appellate brief, Tooker states in a conclusory manner that she
    provided sufficient facts in her petitions to support a prima facie case of retaliation
    remand to allow her a reasonable opportunity to cure the pleading defects. Our analysis in this
    section is not based on any pleading defects, so Tooker’s request for an opportunity to cure
    pleading defects does not apply.
    11
    claim under the Human Rights Act. As to any such claim based on conduct other
    than the alleged 2011 retaliation conduct that was the basis of the First Charge, the
    trial court dismissed these claims based on the District’s “Objections and Motion
    to Strike Plaintiff’s Changes to her Deposition Testimony, Plea to the Jurisdiction,
    Traditional, and No Evidence Motions for Summary Judgment” (hereinafter the
    “Second Motion”). Tooker does not address the grounds in the Second Motion on
    which the trial court dismissed these claims. Tooker does not provide any analysis
    or legal citations showing how the trial court erred in granting the Second Motion
    as to these claims. Even liberally interpreting Tooker’s appellate briefing, we
    cannot conclude that she has adequately briefed this issue. See Tex. R. App. P.
    38.1(i); 
    Kaldis, 424 S.W.3d at 736
    –37.         Therefore, Tooker has waived any
    challenge to the trial court’s granting of the Second Motion as to these claims. See
    
    Kaldis, 424 S.W.3d at 736
    –37.
    D. Has appellant sufficiently briefed a challenge to the trial court’s
    dismissal of her hostile-work-environment claims on the ground that
    she failed to exhaust administrative remedies?
    In its first jurisdictional plea, the District asserted that Tooker had not
    exhausted administrative remedies as to her hostile-work-environment claim. The
    trial court granted the plea on this ground and dismissed this claim. On appeal,
    Tooker has not challenged this dismissal. In fact, in her appellate brief, Tooker
    notes that although she argued in the trial court that the trial court had jurisdiction
    over her hostile-work-environment claim based on the First Charge, she does not
    make this argument on appeal or challenge the trial court’s dismissal of her hostile-
    work-environment claim based on the First Charge.
    Tooker amended her petition and apparently sought to plead another hostile-
    work-environment claim on the premise that she had exhausted administrative
    12
    remedies by means of the Second Charge. In the Second Motion, the District
    asserted, among other things, the following:
    (1) Tooker had not exhausted her administrative remedies as to her
    hostile-work-environment claim because neither the First Charge nor
    the Second Charge were sufficient to exhaust remedies as to this
    claim;
    (2) Tooker’s hostile-work-environment claim is time barred; and
    (3) Tooker has not pleaded and cannot prove that any alleged
    harassment under her hostile-work-environment claim affected a term,
    condition, or privilege of Tooker’s employment because the alleged
    conduct falls short of the severe or pervasive conduct necessary to
    establish such a claim.
    Tooker argues in one section of her appellate brief that the evidence raised a
    fact issue as to each of the essential elements of her hostile-work-environment
    claim.6    Exhaustion of administrative remedies is not one of these elements.
    Tooker also appears to argue in another section of her brief that her hostile-work-
    environment claim is not time-barred.                Tooker, however, has not adequately
    briefed the issue of whether she exhausted her administrative remedies as to her
    hostile-work-environment claim based on the Second Charge. Though Tooker
    6
    In her appellate briefing, Tooker conflates her allegations of actionable retaliation against her
    for engaging in a protected activity with a hostile-work-environment claim based on alleged
    harassment due to a protected status. Tooker asserts that evidence of retaliation raises a fact
    issue as to her hostile-work-environment claim. But, retaliation is not the same as discrimination
    or a hostile work environment. See University of Tex. M.D. Anderson Cancer Center v. Eltonsy,
    
    451 S.W.3d 478
    , 484–85 (Tex. App.—Houston [14th Dist.] 2014, no pet.) (distinguishing
    conduct in which an employer retaliates against an employee for engaging in a protected activity
    from conduct by the employer constituting gender discrimination); Fort Bend Indep. Sch. Dist. v.
    Williams, No. 01-13-00052-CV, 
    2013 WL 4779693
    , at *8–10 (Tex. App.—Houston [1st Dist.]
    Sept. 5, 2013, no pet.) (distinguishing conduct in which an employer retaliates against an
    employee for engaging in a protected activity from conduct creating a hostile work environment
    based on harassment regarding the employee’s protected status and concluding that charge of
    discrimination and the amendment alleging retaliation did not exhaust administrative remedies as
    to the hostile-work-environment claim, even though the charge mentioned a “hostile working
    environment”) (mem. op.).
    13
    does not assert in her opening brief that she exhausted administrative remedies as
    to her hostile-work-environment claim based on the Second Charge, in the section
    discussing the timeliness of this claim, Tooker cites the legal standard for
    exhausting administrative remedies, and states that the facts set forth in the First
    Charge and in the Second Charge amounted to allegations of a hostile work
    environment. Tooker also twice states in a conclusory manner that the trial court
    had jurisdiction over her hostile-work-environment claim based on the Second
    Charge. In a footnote, Tooker states that she does not concede that her hostile-
    work-environment claim based on the Second Charge “was not well-pled for the
    Second and Third Amended Petitions.”
    Though Tooker cites two cases on the general legal standard for exhausting
    administrative remedies in a charge of discrimination, she does not cite any legal
    authorities regarding exhaustion of administrative remedies as to a hostile-work-
    environment claim. More importantly, Tooker does not analyze the language of
    the First Charge or the Second Charge, nor does she apply any legal standard to
    this language in an attempt to show that she exhausted administrative remedies as
    to her hostile-work-environment claim. Tooker has not provided an analysis in
    which she purports to show that the trial court erred in granting the Second Motion
    based on the District’s argument that Tooker had not exhausted administrative
    remedies as to her hostile-work-environment claim.              Even under a liberal
    interpretation of Tooker’s appellate briefing, we cannot conclude that she has
    adequately briefed this issue. See Tex. R. App. P. 38.1(i); 
    Kaldis, 424 S.W.3d at 736
    –37. Therefore, Tooker has waived any challenge to the trial court’s granting
    of the Second Motion as to her hostile-work-environment claim.7 See Kaldis, 424
    7
    Even if Tooker had adequately briefed this issue, we would conclude that Tooker had not
    exhausted administrative remedies as to her hostile-work-environment claim. See Williams,
    
    2013 WL 4779693
    , at 
    *8–10. 14 S.W.3d at 736
    –37.
    E. Has appellant shown that she raised a fact issue as to whether the
    District treated her less favorably than similarly situated male
    employees regarding compensation?
    On appeal, Tooker asserts that the evidence raised a fact issue as to each
    element of her prima facie case on her disparate-compensation claim, in which she
    alleges that her salary was lower than similarly situated male employees. Under
    the McDonnell Douglas framework, one element of this claim is that the District
    treated Tooker less favorably as to salary than similarly situated male employees.
    See College of the 
    Mainland, 436 S.W.3d at 393
    . The Supreme Court of Texas has
    concluded that “[e]mployees are similarly situated if their circumstances are
    comparable in all material respects.” Ysleta Indep. Sch. 
    Dist., 177 S.W.3d at 917
    .
    The United States Court of Appeals for the Fifth Circuit has articulated a similar
    standard, saying that employees are similarly situated if their circumstances are
    “nearly identical.” See 
    Perez, 395 F.3d at 213
    . The District submitted with its
    Second Motion evidence that negated this element of Tooker’s prima facie case
    and showed that Tooker was not similarly situated to the male comparators
    identified by Tooker in the trial court. See College of the 
    Mainland, 436 S.W.3d at 393
    –95. Therefore, to avoid dismissal, Tooker had to submit evidence raising a
    fact issue as to this essential element. See 
    Garcia, 372 S.W.3d at 637
    .
    On appeal, Tooker points to evidence that Proffitt was in the same pay grade
    when he retired in 2011 as Tooker was in 1993.8 We presume for the sake of
    argument that this statement is correct. Tooker then asserts that she performed the
    job duties of a foreman and suggests that she should have received the same salary
    8
    We presume that Tooker has sufficiently briefed her challenge to the dismissal of her disparate-
    compensation claim.
    15
    as Proffitt, the only male comparator Tooker identifies on appeal. But, the evidence
    Tooker cites does not raise a fact issue as to whether she performed the same job
    duties as Proffitt. Tooker has not shown that she and Proffitt (or any other male
    comparator) were similarly situated. See College of the 
    Mainland, 436 S.W.3d at 393
    –95. Therefore, Tooker has not shown that the trial court erred in granting the
    Second Motion as to her disparate-compensation claim and dismissing this claim.
    See College of the 
    Mainland, 436 S.W.3d at 393
    –95; 
    Garcia, 372 S.W.3d at 637
    .
    F. Has appellant challenged all the grounds upon which the trial court
    dismissed appellant’s Whistleblower Act claim?
    Tooker asserts that the District violated the Whistleblower Act by
    suspending her with pay in 2013.       The District sought dismissal of Tooker’s
    Whistleblower Act claim in its “Plea to the Jurisdiction, Traditional, and No
    Evidence Motions for Summary Judgment,” deemed by the trial court to have been
    filed on July 28, 2014 (hereinafter the “Third Motion”). In the Third Motion, the
    District asserted the following grounds:
    (1) Tooker never filed a grievance under the District’s grievance
    procedures regarding her Whistleblower Act claim.
    (2) Tooker cannot establish a causal connection between her email to
    Captain Bonaparte in April 2011 and her administrative leave with
    pay in January 2013.
    (3) Tooker did not report an alleged violation of law to an appropriate
    authority.
    (4) The District would have taken the same action against Tooker
    even if she had not made the alleged report of a violation of law.
    (5) There is no evidence that Tooker suffered an adverse personnel
    action when she was placed on administrative leave with pay.
    (6) There is no evidence that Tooker made a report of a violation of
    law in good faith.
    (7) There is no evidence that, but for making the report to the District
    16
    Police Department in April 2011, Tooker would not have been placed
    on administrative leave with pay in January 2013.
    When, as in this case, the trial court does not specify the grounds upon
    which the trial court relied, we must affirm the trial court’s ruling if any of the
    independent grounds is meritorious. See FM Props. Operating Co. v. City of
    Austin, 
    22 S.W.3d 868
    , 872 (Tex. 2000). In this circumstance, the appealing party
    must challenge all possible grounds on which the motion could have been granted,
    properly or improperly. See FinServ Cas. Corp. v. Transamerica Life Ins. Co.,
    No. 14-14-0838-CV, —S.W.3d—, —, 
    2016 WL 6134442
    , at *6 (Tex. App.—
    Houston [14th Dist.] Oct. 20, 2016, no pet. h.).         Even construing Tooker’s
    appellate brief liberally, we cannot conclude that she has briefed arguments
    challenging each of the independent grounds on which the trial court granted the
    Third Motion as to Tooker’s Whistleblower Act claim. See Navarro v. Grant
    Thornton, LLP, 
    316 S.W.3d 715
    , 719–20 (Tex. App.—Houston [14th Dist.] 2010,
    no pet.).   As to the no-evidence summary-judgment ground that there is no
    evidence that Tooker suffered an adverse personnel action when she was placed on
    administrative leave with pay, Tooker’s opening brief, at most, addresses this
    ground in a single paragraph containing conclusory statements and no citations to
    the record or to legal authority. The briefing is inadequate to constitute a challenge
    to the trial court’s ruling on this ground. Because Tooker has not briefed arguments
    challenging each of the independent grounds on which the trial court granted the
    Third Motion as to Tooker’s Whistleblower Act claim, we overrule Tooker’s
    challenge to the trial court’s dismissal of her Whistleblower Act claim. See 
    id. G. Has
    appellant shown that the trial court erred in granting the Third
    Motion as to appellant’s Leave Act claim?
    The Leave Act allows eligible employees working for covered employers to
    take temporary leave without the risk of losing employment because of
    17
    (1) a serious health condition that makes the employee unable to
    perform the functions of the employee’s position,
    (2) the birth or adoption of a child,
    (3) the placement of a child with the employee for foster care,
    (4) the care of a spouse, child, or parent who has a serious health
    condition, or
    (5) any qualifying exigency (as determined by regulation) arising out
    of the fact that the spouse, or a son, daughter, or parent of the
    employee is on covered active duty (or has been notified of an
    impending call or order to covered active duty) in the Armed Forces.
    (collectively the “Statutory Reasons”). See 29 U.S.C. § 2612 (West, Westlaw
    through 2015 R.S.); Hunt v. Rapides Healthcare Sys., 
    277 F.3d 757
    , 762–63 (5th
    Cir. 2001), abrogated on other grounds by, Burlington N. & Santa Fe Ry. Co. v.
    White, 
    548 U.S. 53
    , 61–67, 
    126 S. Ct. 2405
    , 2411–14, 
    165 L. Ed. 2d 345
    (2006).
    The statute provides a series of substantive rights. See Hunt, 
    277 F.3d 757
    , 763.
    The Leave Act requires a covered employer to allow an eligible employee up to a
    specified amount of unpaid leave in a twelve-month period for one or more of the
    Statutory Reasons. See 29 U.S.C. § 2612; 
    Hunt, 277 F.3d at 763
    . Subject to
    certain provisions of the Leave Act, leave based on the employee’s serious health
    condition or to care for a spouse, child, or parent who has a serious health
    condition may be taken intermittently or on a reduced leave schedule when
    medically necessary. See 29 U.S.C. § 2612(b). When an eligible employee returns
    from leave taken under the Leave Act, the employer must restore the employee to
    the same position or to an equivalent position with equivalent employment
    benefits, pay, and other terms and conditions of employment. See 29 U.S.C. §
    2614(a)(1) (West, Westlaw through 2015 R.S.); 
    Hunt, 277 F.3d at 763
    . The Leave
    Act makes it “unlawful for any employer to interfere with, restrain, or deny the
    18
    exercise of or the attempt to exercise, any right provided under this subchapter.”9
    See 29 U.S.C. § 2615(a)(1) (West, Westlaw through 2015 R.S.); 
    Hunt, 277 F.3d at 763
    . An employer who engages in such unlawful conduct is liable to any eligible
    employee for certain losses incurred by such employee as a result of the unlawful
    conduct. See 29 U.S.C. § 2617(a)(1)(A)(i).
    Tooker asserted a damage claim against the District under title 29, section
    2617 of the United States Code. See 
    id. In the
    Third Motion, the District sought a
    no-evidence summary judgment as to this claim on the ground that there was no
    evidence of the essential element that the District denied Tooker Leave Act
    benefits to which she was entitled. Tooker agrees that this is an essential element
    of her claim. See Brackens v. Dallas Indep. Sch. Dist., No. 3:09-CV-0642-D, 
    2010 WL 5464823
    , at *21 (N.D. Tex. Sept. 20, 2010) (listing denial of Leave Act
    benefits to which the employee was entitled as one of the essential elements of this
    claim). The only evidence Tooker cites as raising a fact issue on this element is the
    following paragraph from an affidavit of Tooker:
    I requested FMLA10 leave in March 2014. I submitted all
    documentation and medical forms but my FMLA [sic] was never
    approved. In 2012 and 2013, I told DeLisle that my son was very ill.
    He never suggested FMLA leave. I had to use vacation or sick days.
    Some of these days were ultimately counted against me and affect my
    attendance record. I have been under the doctor care [sic] for years
    and would have benefitted from intermittent FMLA leave. I did not
    know this would qualify for FMLA until my attorney told me about it.
    She requested it as well on my behalf in March 2014 but did not hear
    9
    The Leave Act also makes it unlawful for any employer to discharge or in any other manner
    discriminate against any individual for engaging in certain protected activities. See 29 U.S.C. §
    2615(a)(2) & (b). Both in the trial court and on appeal, Tooker has stated that she is not
    asserting a Leave Act claim based on these provisions at this time.
    10
    Although the term “FMLA” is not defined or explained in the affidavit, “FMLA” is an
    acronym often used to refer to the Leave Act.
    19
    back from [the District’s] attorney[]s until July 2014. To date, I still
    have not received an answer regarding FMLA. Since I have been
    suspended and notified of my termination, it really is too late.
    In reviewing a no-evidence summary judgment, we ascertain whether the
    nonmovant pointed out summary-judgment evidence raising a genuine issue of fact
    as to the essential elements attacked in the no-evidence motion. Johnson v. Brewer
    & Pritchard, P.C., 
    73 S.W.3d 193
    , 206–08 (Tex. 2002). In our de novo review of
    a trial court’s summary judgment, we consider all the evidence in the light most
    favorable to the nonmovant, crediting evidence favorable to the nonmovant if
    reasonable jurors could, and disregarding contrary evidence unless reasonable
    jurors could not. Mack Trucks, Inc. v. Tamez, 
    206 S.W.3d 572
    , 582 (Tex. 2006).
    The evidence raises a genuine issue of fact if reasonable and fair-minded jurors
    could differ in their conclusions in light of all of the summary-judgment evidence.
    Goodyear Tire & Rubber Co. v. Mayes, 
    236 S.W.3d 754
    , 755 (Tex. 2007).
    The above-quoted paragraph does not raise a raise a genuine fact issue as to
    whether the District denied Tooker Leave Act benefits to which she was entitled.11
    See Brackens, 
    2010 WL 5464823
    , at *21.                   Tooker has not shown that the
    summary-judgment evidence raised a genuine fact question on this issue. See 
    id. Because Tooker
    has not shown that the trial court erred in granting the Third
    Motion as to Tooker’s Leave Act claim, we overrule Tooker’s challenge to the trial
    court’s dismissal of this claim.
    H. Has appellant shown that the trial court erred in dismissing her
    overtime-compensation claim under the Fair Labor Act?
    Tooker asserted a claim against the District under the Fair Labor Act for
    11
    In her briefing Tooker seems to suggest that the District does not dispute any of the essential
    elements of her Leave Act claim. The District disputes whether the District denied Tooker Leave
    Act benefits to which she was entitled.
    20
    unpaid overtime compensation. See 29 U.S.C. § 216(b) (West, Westlaw through
    2015 R.S.) (providing statutory damage claim for unpaid overtime compensation
    against employer who fails to provide overtime compensation as required by
    section 207 of the Fair Labor Act).
    The Fair Labor Act mandates that “[e]xcept as otherwise provided in
    [section 207], no employer shall employ any of his employees . . . for a workweek
    longer than forty hours unless such employee receives compensation for his
    employment in excess of the hours above specified at a rate not less than one and
    one-half times the regular rate at which he is employed.” 29 U.S.C. § 207(a)(1)
    (West, Westlaw through 2015 R.S.).
    As a public employee, Tooker could receive compensatory time off in lieu of
    overtime pay at a rate of at least one-and-a-half hours for each hour of employment
    for which overtime compensation is required. See 29 U.S.C. § 207(o). The
    employer and employee must agree on the compensatory-time-off arrangement
    before overtime work is performed. See 
    id. The evidence
    before the trial court established that Tooker and the District
    agreed Tooker would earn one-and-a-half hours of compensatory time for each
    hour of work in excess of forty hours per week. Until 2013, when the District
    ended the practice of having maintenance-department employees “on-call” during
    non-business hours, the Maintenance Department policy allowed department
    employees, including Tooker, to earn compensatory time for being “on-call,” even
    if the employee did not receive any calls and did not work any hours while “on
    call.”
    An employer who knows that an employee is working overtime cannot stand
    by and allow an employee to perform overtime work without proper compensation,
    even if the employee does not make a claim for the overtime compensation.
    21
    Harvill v. Westward Communications, L.L.C., 
    433 F.3d 428
    , 441 (5th Cir. 2005).
    If the employee fails to notify the employer or deliberately prevents the employer
    from acquiring knowledge of the overtime work, the employer does not violate
    section 207 of the Fair Labor Act by failing to provide compensation for the
    overtime hours.     
    Id. An employee
    bringing a claim for unpaid overtime
    compensation under the Fair Labor Act first must demonstrate she has performed
    work for which she was compensated improperly, and the employee must produce
    sufficient evidence to show the amount and extent of that work as a matter of just
    and reasonable inference. 
    Id. On appeal,
    Tooker asserts that the evidence raised a fact issue as to whether
    the District denied her overtime benefits from 2010 to 2012 and that the trial court
    erred in dismissing her overtime-compensation claim under the Fair Labor Act.
    Tooker asserts that two paragraphs in one of her affidavits and a two-page
    document that she created raise a genuine fact issue as to this claim. In one
    paragraph in the affidavit Tooker states she was supposed to stop working at 4:30
    p.m. Tooker then says that “[e]very day that I worked, I was required to lock up
    and take calls regarding HVAC problems until I was instructed not to work
    overtime or stay pas[t] 4:40 p.m.” In a sheet Tooker prepared, she lists “Earned
    Comp Time” for various dates in 2010, 2011, and 2012. Though it is not clear, it
    appears that Tooker calculates that she worked 42.5 weeks in each of these years
    and that each day she worked 21 extra minutes. This unsubstantiated and
    speculative estimate of uncompensated overtime does not raise a genuine fact issue
    to preclude summary judgment as to Tooker’s overtime-compensation claim under
    the Fair Labor Act. See Ihegword v. Harris Cnty. Hosp. Dist., 
    929 F. Supp. 2d 635
    ,
    
    668 A.K. Marsh. 7
    , 2013), aff’d, 555 Fed. Appx. 372 (5th Cir. 2014).
    In the other cited paragraph in her affidavit, Tooker states that she prepared
    22
    a document showing her calculations of compensatory time. She says she made
    these calculations based on documents the District produced in this lawsuit and
    that these documents “only show comp-time as straight time.” In her affidavit,
    Tooker does not identify the documents to which she refers.12 In any event,
    beyond the calculation of the 21 minutes extra per day discussed above, in her
    calculation document Tooker simply lists dates along with a corresponding number
    of compensatory hours earned, totals the hours, and adds 50% of the total to
    achieve time-and-a-half. In her calculations, Tooker does not reflect whether she
    timely submitted a form to the District claiming to have earned any of these hours
    of compensatory time. Nor does Tooker state how many hours of compensatory
    time the District gave her for the items listed in these calculations. Significantly,
    under the District’s policies during 2010-2012, Tooker could earn compensatory
    hours for reasons other than working more than forty hours in a week. For
    example, Tooker could have earned compensatory hours for being “on call.”
    Listing numbers of compensatory hours Tooker claims she earned is not the same
    as saying that she worked more than forty hours during any week because she
    might have earned the hours by being “on call.” Nowhere in her calculation
    document does Tooker state or clearly indicate that she worked more than forty
    hours in a week. Tooker’s conclusory, unsubstantiated, and speculative calculation
    document does not raise a genuine fact issue to preclude summary judgment as to
    Tooker’s overtime-compensation claim under the Fair Labor Act. See 
    Ihegword, 929 F. Supp. 2d at 668
    .
    In her affidavit, Tooker states, “[f]or instance, I worked 4 hours of overtime
    on January 14, 2010, as reflected in [the calculation document]. I should have
    received 6 hours of comp-time but [the District] only gave me 4 hours straight
    12
    In her appellate brief, Tooker says that the documents are attached to the Second Motion as
    Exhibit C-5.
    23
    time.” Evidence from the District shows that on that date Tooker earned 4 hours of
    compensatory time for being “on call,” not for working more than forty hours in a
    week. Presuming that Tooker’s statements in the affidavit raise a genuine fact
    issue as to whether she worked more than forty hours that week, the evidence also
    contained a document Tooker signed, showing that she was aware that “[a]ll time
    worked will be reflected on [the] time card” and that compensatory-time-earned
    sheets must be turned in to the Foreman and the Secretary by noon on Tuesday of
    the week after the compensatory time was earned. Employees asserting claims
    under the Fair Labor Act are bound by such policies. See Nieddu v. Lifetime
    Fitness, Inc., 
    977 F. Supp. 2d 686
    , 698–99 (S.D. Tex. 2013). Tooker did not submit
    evidence showing that her time cards reflected that she worked more than forty
    hours in a week and that she did not receive one-and-a-half compensatory hours for
    every hour worked in excess of forty during that week. Nor did Tooker submit any
    evidence showing that the District did not give her credit for the proper amount of
    compensatory time earned, even though Tooker submitted a form to obtain
    compensatory time based on having worked more than forty hours in a week.
    The evidence Tooker cites does not raise a raise a genuine fact issue as to
    her overtime-compensation claim under the Fair Labor Act. See 
    Harvill, 433 F.3d at 441
    ; 
    Ihegword, 929 F. Supp. 2d at 668
    . We overrule Tooker’s challenge to the
    trial court’s dismissal of this claim.
    I. Did the trial court err in dismissing appellant’s retaliation claim under
    the Fair Labor Act?
    The Fair Labor Act makes it unlawful for any person to “discharge or in any
    other manner discriminate against any employee because such employee has filed
    any complaint or instituted or caused to be instituted any proceeding under or
    related to this chapter.” 29 U.S.C. § 215(a)(3) (West, Westlaw through 2015 R.S.).
    24
    A retaliation claim under the Fair Labor Act is subject to the McDonnell
    Douglas analytical framework. See Kanida v. Gulf Coast Med. Pers., LP, 
    363 F.3d 568
    , 577 (5th Cir. 2004). For a Fair Labor Act retaliation claim the plaintiff must
    make a prima facie showing of (1) participation in protected activity under the Fair
    Labor Act, (2) an adverse employment action, and (3) a causal link between the
    activity and the adverse action.13 See Hagan v. Echostar Satellite, LLC, 
    529 F.3d 617
    , 624 (5th Cir. 2008).
    The trial court dismissed Tooker’s Fair Labor Act retaliation claim based on
    the District’s grounds that there is no evidence of any of the three elements of the
    prima facie case.14 On appeal, Tooker asserts that the evidence raises a fact issue
    as to each element.
    Tooker filed the original petition in the trial court, asserting a claim against
    the District for violation of the Fair Labor Act and alleging that the District failed
    to compensate her for all of the overtime she had worked. This action constitutes
    participation in protected activity under the Fair Labor Act. See 29 U.S.C. §
    215(a)(3); 
    Hagan, 529 F.3d at 624
    .
    For      purposes       of     a    Fair      Labor      Act      retaliation     claim,
    an adverse employment action must include conduct that “a reasonable employee
    would have found . . . materially adverse, which in this context means it well might
    have dissuaded a reasonable worker from [participating in the protected activity].”
    13
    To succeed in a Fair Labor Act retaliation claim, a plaintiff need not show that she had a
    meritorious Fair Labor Act compensation claim; therefore, Tooker’s failure to show that the trial
    court erred in dismissing her Fair Labor Act compensation claim does not affect this court’s
    analysis of her Fair Labor Act retaliation claim. See Little v. Technical Specialty Prods.,
    LLC, 
    940 F. Supp. 2d 460
    , 478 (E.D. Tex. 2013).
    14
    The trial court also impliedly dismissed the Federal Labor Act retaliation claim to the extent
    Tooker relied on a termination of her employment as the adverse employment action, based on a
    traditional ground in the Second Motion. Tooker has not challenged this ruling on appeal.

    Tooker asserts that the District engaged in an adverse employment action
    when Jeff DeLisle gave her a memorandum on February 22, 2013, less than a
    month after she filed this lawsuit. In this memorandum, DeLisle stated as follows:
    In addition to your issues above it has come to my attention that you
    have alleged that you have not been properly compensated for
    overtime work. You are hereby directed not to work any overtime
    unless specifically asked to do so by either Wilton Curry or me.
    Failure to follow these directives will be viewed as insubordination
    and/or misconduct; therefore, resulting in disciplinary action up to and
    including a recommendation for termination.
    Evidence before the trial court showed a District policy requiring all nonexempt
    employees to have the approval of their supervisor before working overtime.
    Thus, before the lawsuit, Tooker was permitted to seek approval to work overtime.
    DeLisle’s memorandum changed that. Tooker was not to work overtime unless the
    named individuals asked her to do so, and DeLisle threatened Tooker with a
    potential recommendation for termination if she failed to comply with this
    directive. The evidence raises a fact issue as to (1) whether under the new
    restriction, Tooker could not initiate an overtime possibility as other employees
    were permitted to do under the District’s policy; and (2) whether the new
    restriction effectively eliminated Tooker’s overtime hours unless she received a
    specific request. Because the potential need for overtime work is sometimes only
    26
    within the employee’s knowledge, an employee who is barred from seeking prior
    approval for overtime might effectively lose that overtime and so might be
    dissuaded from pursuing the protected activity.
    The evidence raises a genuine fact issue as to whether, when DeLisle gave
    Tooker the overtime-restriction memorandum and had her sign it, Tooker had
    worked and been compensated for overtime in the past under a policy requiring
    only prior supervisor approval. In the memorandum, DeLisle noted Tooker’s
    overtime-compensation claim and then directed Tooker not to work any overtime
    unless specifically asked to do so by either Wilton Curry or DeLisle. The evidence
    raises a genuine fact issue as to whether a reasonable employee, who had worked
    overtime in the past and been compensated for it, would have found DeLisle’s
    memorandum to be materially adverse conduct due to DeLisle’s change in policy,
    apparently only as to that one employee, from a requirement of prior approval to a
    requirement that Curry or DeLisle specifically ask the employee to work overtime.
    See White v. Denton Cnty., No. 4:13CV13, 
    2015 WL 5047955
    , at *6–7 (E.D. Tex.

    2010 WL 797145
    , at *5–6 (Tex. App.—Austin Feb. 19, 2010, no pet.) (mem. op.). On
    this record, we see a fact issue as to whether the overtime-restriction memorandum
    “well might” have dissuaded a reasonable worker in this context from making or
    supporting a Fair Labor Act compensation claim. See White, 
    2015 WL 5047955
    ,
    at *6–7; Williams, 
    2010 WL 797145
    , at *5–6.
    The District cites two authorities in support of the position that an
    employer’s limitation on an employee’s ability to work overtime cannot constitute
    an adverse employment action. The first authority is title 29, section 785.13 of the
    Code of Federal Regulations. See 29 C.F.R. 785.13 (stating that “In all such cases
    it is the duty of the management to exercise its control and see that the work is not
    27
    performed if it does not want it to be performed. It cannot sit back and accept the
    benefits without compensating for them. The mere promulgation of a rule against
    such work is not enough. Management has the power to enforce the rule and must
    make every effort to do so.”). This regulation addresses the need for employers to
    enforce policies restricting the performance of overtime. See 
    id. This regulation
    does not address whether an employer’s increase in the restriction that it places on
    overtime work as to a specific employee — coupled with threats of discipline for
    “insubordination and/or misconduct” resulting in action “up to and including a
    recommendation for termination” — after she files a Fair Labor Act compensation
    claim may constitute an adverse employment action in the employee’s Fair Labor
    Act retaliation claim. See 
    id. The District
    also cites an opinion form the United
    State Court of Appeals for the Fifth Circuit.      See Von Friewalde v. Boening
    Aerospace Operations, Inc., 339 Fed. Appx. 448, 459 (5th Cir. 2009). It is an
    unpublished opinion and is not precedential. See 5th Cir. R. 47.5.4. Even if it
    were, the court did not address any Federal Labor Act retaliation claim; instead, the
    court concluded that the employer’s overtime policies may be considered and
    given effect in determining whether the employee has made the initial showing
    required in a Fair Labor Act compensation claim. See 
    id. The District
    has not cited any authority holding that an increased restriction
    on an employee’s ability to work overtime coupled with threats of discipline “up to
    and including a recommendation for termination” cannot constitute an adverse
    employment action. The Third Court of Appeals has concluded that evidence an
    employer’s action decreased the employee’s opportunity to work overtime and
    earn overtime pay can constitute evidence that the action is an adverse employment
    action. See Williams, 
    2010 WL 797145
    , at *5–6. We conclude that the evidence
    raised a genuine fact issue as to whether DeLisle’s memorandum constituted an
    28
    adverse employment action for the purposes of the prima facie case in Tooker’s
    Federal Labor Act retaliation claim. See White, 
    2015 WL 5047955
    , at *6–7;
    Williams, 
    2010 WL 797145
    , at *5–6.
    The final element of the Tooker’s prima facie case requires some “causal
    link” between Tooker’s filing of this lawsuit and the alleged adverse employment
    action — DeLisle issuing the memorandum to Tooker. See 
    Hagan, 529 F.3d at 624
    . A causal link is shown when the evidence demonstrates that the adverse
    employment action was based in part on knowledge of the employee’s protected
    activity. See Medina v. Ramsey Steel Co., 
    238 F.3d 674
    , 684 (5th Cir. 2001).
    While temporal proximity is not determinative, close timing between the
    employee’s protected activity and the adverse employment action may provide a
    causal link for the purposes of the employee’s prima facie case in a retaliation
    claim. Swanson v. Gen. Servs. Admin., 
    110 F.3d 1180
    , 1188 (5th Cir. 1997). The
    adverse employment action occurred less than a month after Tooker engaged in a
    protected activity under the Fair Labor Act. In the memorandum DeLisle noted
    Tooker’s protected activity and appeared to indicate that he imposed the additional
    restriction on overtime work in response to the protected activity. We thus find a
    genuine fact issue as to whether there is a causal link between Tooker’s protected
    activity and the adverse employment action.      See Mora v. Affiliated Customs
    Brokers USA, Inc., No. EP-13-CV-367-KC, 
    2015 WL 12551108
    , at *9 (E.D. Tex.
    Aug. 26, 2015).
    The evidence raises a genuine fact issue as to each element of Tooker’s
    prima facie case, and the District did not seek dismissal based on any alleged
    legitimate, nondiscriminatory reason, or on any other ground as to the Fair Labor
    Act retaliation claim based on DeLisle’s memorandum. We thus sustain Tooker’s
    29
    appellate challenge to the trial court’s dismissal of this claim. 15
    III.   CONCLUSION
    Because the evidence raises a genuine fact issue as to each element of
    Tooker’s prima facie case in her Fair Labor Act retaliation claim based on the
    overtime-restriction memorandum, the trial court erred in dismissing this claim.
    We thus sustain the part of Tooker’s fourth appellate issue in which she challenges
    the trial court’s dismissal of this claim. As to all of the other claims whose
    dismissal Tooker challenges on appeal, we have addressed all of Tooker’s
    appellate arguments necessary to the disposition of this appeal without finding any
    reversible error. We thus overrule all of Tooker’s other appellate issues as well as
    the remainder of Tooker’s fourth issue. We reverse the trial court’s judgment as to
    the Fair Labor Act retaliation claim based on the overtime-restriction
    memorandum, remand this claim for further proceedings, and affirm the remainder
    of the trial court’s judgment.
