    DONOHUE v. AMN SERVICES, LLC
    S253677
    Opinion of the Court by Liu, J.
    Under California law, employers must generally provide
    employees with one 30-minute meal period that begins no later
    than the end of the fifth hour of work and another 30-minute
    meal period that begins no later than the end of the tenth hour
    of work. (Lab. Code, § 512, subd. (a); Industrial Welfare
    Commission (IWC) wage order No. 4-2001, § 11(A) (Wage Order
    No. 4).) If an employer does not provide an employee with a
    compliant meal period, then “the employer shall pay the
    employee one additional hour of pay at the employee’s regular
    rate of compensation for each workday that the meal . . . period
    is not provided.” (Lab. Code, § 226.7, subd. (c); Wage Order
    No. 4, § 11(B).)
    In this case, we decide two questions of law relating to
    meal periods. First, we hold that employers cannot engage in
    the practice of rounding time punches — that is, adjusting the
    hours that an employee has actually worked to the nearest
    preset time increment — in the meal period context. The meal
    period provisions are designed to prevent even minor
    infringements on meal period requirements, and rounding is
    incompatible with that objective. Second, we hold that time
    records showing noncompliant meal periods raise a rebuttable
    presumption of meal period violations, including at the
    summary judgment stage.

    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    In light of our holdings, we reverse the Court of Appeal’s
    judgment and remand the matter to permit either party to bring
    a new summary adjudication motion as to the meal period claim.
    (See TRB Investments, Inc. v. Fireman’s Fund Ins. Co. (2006) 
    40 Cal.4th 19
    , 23, 31–32 (TRB Investments).) The remand offers
    the parties the opportunity to present evidence and arguments
    bearing on the question of liability in light of our analysis here.
    I.
    Defendant AMN Services, LLC (AMN) is a healthcare
    services and staffing company that recruits nurses for
    temporary contract assignments. Between September 2012 and
    February 2014, plaintiff Kennedy Donohue worked as a nurse
    recruiter at AMN’s San Diego offices. In that role, Donohue did
    not have predetermined shifts but was expected to work eight
    hours per day. Per AMN’s company policy, nurse recruiters
    were provided with 30-minute meal periods beginning no later
    than the end of the fifth hour of work. AMN’s policy and
    trainings emphasized that the meal period was an
    “uninterrupted 30 minute” break, during which employees were
    “relieved of all job duties,” were “free to leave the office site,” and
    “control[led] the time.”        The policy also specified that
    supervisors should not “impede or discourage team members
    from taking their break.”
    Until April 2015, AMN used an electronic timekeeping
    system called Team Time to track its employees’ compensable
    time. Employees used their work desktop computers to punch
    in and out of Team Time, including at the beginning of the day,
    at the beginning of lunch, at the end of lunch, and at the end of
    the day. Employees could also ask to manually adjust any
    inaccurate time punches — for example, if they forgot to clock
    2
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    out for lunch or if they worked when they were clocked out. For
    purposes of calculating work time and compensation, Team
    Time rounded the time punches to the nearest 10-minute
    increment. For example, if an employee clocked out for lunch at
    11:02 a.m. and clocked in after lunch at 11:25 a.m., Team Time
    would have recorded the time punches as 11:00 a.m. and 11:30
    a.m. Although the actual meal period was 23 minutes, Team
    Time would have recorded the meal period as 30 minutes.
    Similarly, if an employee clocked in for work at 6:59 a.m. and
    clocked out for lunch at 12:04 p.m., Team Time would have
    rounded the time punches to 7:00 a.m. and 12:00 p.m. In that
    case, the actual meal period started after five hours and five
    minutes of work, but Team Time would have recorded the meal
    period as starting after exactly five hours of work.
    AMN also used Team Time to manage potentially
    noncompliant meal periods. Before September 2012, whenever
    Team Time records showed a missed meal period, a meal period
    shorter than 30 minutes, or a meal period taken after five hours
    of work, AMN assumed there had been a meal period violation
    and paid the employee a premium wage. In September 2012,
    AMN added a feature to Team Time to comply with the meal
    period requirements articulated in Brinker Restaurant Corp. v.
    Superior Court (2012) 
    53 Cal.4th 1004
     (Brinker): When an
    employee recorded a missed, short, or delayed meal period, a
    dropdown menu would appear on Team Time. The dropdown
    menu prompted the employee to choose one of three options: (1)
    “I was provided an opportunity to take a 30 min break before the
    end of my 5th hour of work but chose not to”; (2) “I was provided
    an opportunity to take a 30 min break before the end of my 5th
    hour of work but chose to take a shorter/later break”; (3) “I was
    not provided an opportunity to take a 30 min break before the
    3
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    end of my 5th hour of work.” The employee was required to
    choose an option before submitting his or her timesheet at the
    end of the pay period. If the employee chose the first or second
    option, then AMN assumed the employee was provided with a
    compliant meal period but voluntarily chose not to take one, and
    the employee did not receive premium pay for a meal period
    violation. If the employee chose the third option, then AMN
    assumed there had been a meal period violation and paid the
    employee a premium wage. In addition, at the end of each
    biweekly pay period, employees were required to sign a
    certification statement: “By submitting this timesheet, I am
    certifying that I have reviewed the time entries I made and
    confirm they are true and accurate. I am also confirming that
    . . . I was provided the opportunity to take all meal breaks to
    which I was entitled, or, if not, I have reported on this timesheet
    that I was not provided the opportunity to take all such meal
    breaks . . . .”
    AMN relied on the rounded time punches generated by
    Team Time to determine whether a meal period was short or
    delayed. Consider the example above, where a 23-minute lunch
    starting at 11:02 a.m. and ending at 11:25 a.m. was recorded on
    Team Time as a 30-minute lunch starting at 11:00 a.m. and
    ending at 11:30 a.m. Before September 2012, AMN would not
    have paid a premium wage for this lunch because it would have
    appeared as a full 30-minute meal period in the Team Time
    records. Similarly, after September 2012, the dropdown menu
    would not have been triggered for this lunch because it would
    have appeared as a compliant meal period on Team Time. In
    other words, Team Time would not have prompted the employee
    taking the lunch to indicate whether there had been a meal
    period violation.
    4
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    In April 2014, Donohue filed a class action lawsuit against
    AMN. Donohue alleged various wage and hour violations,
    including the meal period claim at issue here. In October 2015,
    the trial court certified a class of all nonexempt California nurse
    recruiters who were employed by AMN between April 23, 2010
    and April 26, 2015 with respect to the meal period claim. April
    26, 2015 marks the end of the class period because on that date
    AMN switched to a timekeeping system that does not round
    time entries.
    In November 2016, Donohue filed a motion for summary
    adjudication. As to the meal period claim, Donohue argued that
    AMN denied its employees compliant meal periods, improperly
    rounded time records for meal periods using Team Time, and
    failed to pay premium wages for noncompliant meal periods. To
    support the motion, Donohue submitted her testimony that
    AMN had an office culture that discouraged employees from
    taking full and timely lunches. Donohue also provided a
    declaration from an expert witness, a statistics professor.
    According to the expert, the use of Team Time resulted in the
    denial of premium wages for 40,110 short lunches and 6,651
    delayed lunches during the class period, which totaled
    $802,077.08. The expert calculated the number of noncompliant
    lunches for which no premium wages were paid by comparing
    the rounded time records for meal periods to the actual time
    records. For example, the expert would have counted a 23-
    minute lunch starting at 11:02 a.m. and ending at 11:25 a.m.,
    recorded on Team Time as a 30-minute lunch starting at 11:00
    a.m. and ending at 11:30 a.m., as an uncompensated short
    lunch.
    AMN filed a cross-motion for summary judgment or, in the
    alternative, summary adjudication. As to the meal period claim,
    5
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    AMN contended that it did not have a uniform policy or practice
    of denying employees compliant meal periods. It also argued
    that Donohue did not plead in the operative complaint that
    AMN’s rounding policy resulted in meal period violations. AMN
    submitted the declarations of 40 class members in support of its
    motion. Thirty of the nurse recruiters stated that they “always”
    or “usually” took lunches that were at least 30 minutes long.
    Other recruiters said that they only “sometimes” took 30-minute
    lunches but that it was their choice to forgo a full lunch on the
    other days. No declarant stated that a supervisor had tried to
    discourage him or her from taking a full or timely meal period.
    AMN also submitted a declaration from its expert witness,
    a labor economist and statistician. The expert explained that
    because AMN’s rounding policy sometimes rounded meal period
    times up and sometimes down, AMN sometimes paid employees
    for a few extra minutes they did not work and sometimes did not
    pay them for a few minutes that they did work. Unlike
    Donohue’s expert, AMN’s expert did not account for meal period
    premium wages that would have been paid based on actual meal
    period times. According to the expert, AMN’s practice of
    rounding meal period times evened out over time and actually
    resulted in the overcompensation of the class by 85 work hours.
    The expert also stated that based on the nurse recruiters’ actual
    time punches, the average length of a meal period during the
    class period was 45.6 minutes.
    The trial court granted AMN’s motion for summary
    judgment and denied Donohue’s motion for summary
    adjudication, including on the meal period claim. The court
    concluded there was insufficient evidence that AMN had a policy
    or practice of denying employees compliant meal periods.
    According to the court, AMN’s meal period policy complied with
    6
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    California law, and its practice of rounding the time punches for
    meal periods was proper. The court said that even if no case has
    ever applied rounding to meal periods, “the rationale behind
    allowing rounding for work time would be the same for meal
    break time.” According to the court, AMN’s rounding policy
    fairly compensated employees over time, and there was
    insufficient evidence that supervisors at AMN prevented
    employees from taking compliant meal periods.
    The Court of Appeal affirmed and generally agreed with
    the trial court’s reasoning as to the meal period claim. The court
    decided that it was proper for AMN to round time punches for
    meal periods. (Donohue v. AMN Services, LLC (2018) 
    29 Cal.App.5th 1068
    , 1086–1092 (Donohue).) According to the
    court, the plain text of Labor Code section 512 and Wage Order
    No. 4, which govern meal periods, does not prohibit rounding.
    (Donohue, at p. 1087.) The court explained that rounding “ ‘is a
    practical method for calculating worktime and can be a neutral
    calculation tool for providing full payment to employees’ ” and
    that no case law suggests rounding does not apply to meal
    periods. (Id. at p. 1090.) The court rejected Donohue’s
    argument that rounding meal period time punches “ ‘would
    quickly eviscerate employee[s’] statutory right to full 30 minute
    meal periods.’ ” (Ibid.)
    The court also concluded that AMN’s rounding policy was
    neutral on its face and as applied, as required by California law.
    (Donohue, supra, 29 Cal.App.5th at pp. 1083–1086.) The court
    agreed with AMN that the rounding policy fully compensated
    employees over time and actually resulted in the
    overcompensation of the class as a whole. (Id. at p. 1084.) The
    court rejected Donohue’s argument that the rounding policy did
    not properly pay employees premium wages for meal period
    7
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    violations. (Id. at p. 1090.) According to the court, “the
    neutrality of a rounding policy does not depend on the frequency
    of penalties.” (Ibid.)
    In addition, the court rejected Donohue’s argument that
    time records showing missing, short, or delayed meal periods
    give rise to a rebuttable presumption of meal period violations.
    (Donohue, supra, 29 Cal.App.5th at pp. 1087–1088.) In the
    court’s view, this rebuttable presumption applies only at the
    class certification stage, not at the summary judgment stage.
    (Ibid.) Finally, the court considered Donohue’s testimony that
    AMN’s office culture discouraged employees from taking full and
    timely lunches. (Id. at p. 1091.) The court noted that Donohue
    never indicated a meal period violation on Team Time and
    always certified that her timesheet was accurate. (Ibid.) Thus,
    the court concluded, her testimony was insufficient to raise a
    triable issue of material fact as to the meal period claim.
    We granted review to address two questions of law
    relating to the meal period claim: whether an employer may
    properly round time punches for meal periods, and whether time
    records showing noncompliant meal periods raise a rebuttable
    presumption of meal period violations.
    II.
    We first examine whether the practice of rounding time
    punches, which was developed for the purpose of calculating
    wages, can be properly applied to the meal period context. To
    be clear, the question is not whether AMN’s rounding policy
    resulted in the proper compensation of employees for all time
    worked. Donohue does not dispute that the rounding policy
    overcompensated the class by 85 work hours, as AMN’s expert
    concluded, when considering only compensation for time
    8
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    worked. Instead, the issue is whether AMN’s rounding policy
    resulted in the proper payment of premium wages for meal
    period violations. AMN’s claim that it overpaid the class based
    on time worked does not address this issue.
    AMN, for its part, does not argue that any meal periods
    rounded to 30 minutes are per se lawful. Rather, it argues that
    the undisputed evidence shows that no meal period violations
    occurred for which premium wages were not paid. AMN asserts
    that this evidence, regardless of its use of rounding, supports
    judgment on the meal period claim. But because AMN asserted
    that rounding applies to meal periods as an affirmative defense
    and because the trial court certified a meal period class on the
    basis of this question, the issue of rounding is properly before
    us.
    The issue arises solely under state law because the federal
    Fair Labor Standards Act of 1938 (
    29 U.S.C. § 201
     et seq.) does
    not require employers to provide meal periods to employees.
    (Mitchell v. JCG Industries, Inc. (7th Cir. 2014) 
    745 F.3d 837
    ,
    840.) In California, “wage and hour claims are today governed
    by two complementary and occasionally overlapping sources of
    authority: the provisions of the Labor Code, enacted by the
    Legislature, and a series of 18 wage orders, adopted by the
    IWC.” (Brinker, 
    supra,
     53 Cal.4th at p. 1026.) “The IWC is the
    state agency empowered to promulgate wage orders, which are
    legislative regulations specifying minimum requirements with
    respect to wages, hours, and working conditions.” (Augustus v.
    ABM Security Services, Inc. (2016) 
    2 Cal.5th 257
    , 262, fn. 5
    (ABM Security).)
    “The IWC’s wage orders are to be accorded the same
    dignity as statutes. They are ‘presumptively valid’ legislative
    9
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    regulations of the employment relationship [citation],
    regulations that must be given ‘independent effect’ separate and
    apart from any statutory enactments [citation].” (Brinker,
    
    supra,
     53 Cal.4th at p. 1027.) “When construing the Labor Code
    and wage orders, we adopt the construction that best gives effect
    to the purpose of the Legislature and the IWC. [Citations.]
    Time and again, we have characterized that purpose as the
    protection of employees—particularly given the extent of
    legislative concern about working conditions, wages, and hours
    when the Legislature enacted key portions of the Labor Code.
    [Citations.] In furtherance of that purpose, we liberally
    construe the Labor Code and wage orders to favor the protection
    of employees.” (ABM Security, supra, 2 Cal.5th at p. 262.)
    Wage Order No. 4, which applies to professional, clerical,
    mechanical, and similar occupations, applies to the certified
    class of AMN nurse recruiters here. (Wage Order No. 4, § 2(O).)
    This wage order and the relevant statute provide: “No employer
    shall employ any person for a work period of more than five (5)
    hours without a meal period of not less than 30 minutes . . . .
    Unless the employee is relieved of all duty during a 30 minute
    meal period, the meal period shall be considered an ‘on duty’
    meal period and counted as time worked.” (Wage Order No. 4,
    § 11(A); accord, Lab. Code, § 512, subd. (a) [“An employer shall
    not employ an employee for a work period of more than five
    hours per day without providing the employee with a meal
    period of not less than 30 minutes . . . . An employer shall not
    employ an employee for a work period of more than 10 hours per
    day without providing the employee with a second meal period
    of not less than 30 minutes . . . .”].)
    This means that employers must generally provide “a first
    meal period [of at least 30 minutes] no later than the end of an
    10
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    employee’s fifth hour of work, and a second meal period [of at
    least 30 minutes] no later than the end of an employee’s 10th
    hour of work.” (Brinker, 
    supra,
     53 Cal.4th at p. 1041.) In
    Brinker, we clarified that an “employer satisfies this obligation
    if it relieves its employees of all duty, relinquishes control over
    their activities and permits them a reasonable opportunity to
    take an uninterrupted 30-minute break, and does not impede or
    discourage them from doing so. . . . [¶] . . . [T]he employer is not
    obligated to police meal breaks and ensure no work thereafter is
    performed.” (Id. at p. 1040.) There is no meal period violation
    if an employee voluntarily chooses to work during a meal period
    after the employer has relieved the employee of all duty. (Id. at
    pp. 1040–1041.) The voluntariness of an employee’s choice
    matters because “an employer may not undermine a formal
    policy of providing meal breaks by pressuring employees to
    perform their duties in ways that omit breaks.” (Id. at p. 1040.)
    If an employer does not provide an employee with a
    compliant meal period, then the employer must provide the
    employee with premium pay for the violation. Specifically, the
    relevant wage order and statute provide: “If an employer fails
    to provide an employee a meal period in accordance with the
    applicable provisions of this order, the employer shall pay the
    employee one (1) hour of pay at the employee’s regular rate of
    compensation for each workday that the meal period is not
    provided.” (Wage Order No. 4, § 11(B); accord, Lab. Code,
    § 226.7, subd. (c) [“If an employer fails to provide an employee a
    meal . . . period in accordance with a state law, including, but
    not limited to, an applicable statute or applicable regulation,
    standard, or order of the Industrial Welfare Commission . . . the
    employer shall pay the employee one additional hour of pay at
    the employee’s regular rate of compensation for each workday
    11
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    that the meal . . . period is not provided.”].) Under this
    provision, even a minor infringement of the meal period triggers
    the premium pay obligation. In addition to providing premium
    pay, the employer must compensate the employee for any time
    worked during the meal period if “it ‘knew or reasonably should
    have known that the worker was working through the
    authorized meal period.’ ” (Brinker, supra, 53 Cal.4th at
    p. 1040, fn. 19.) To avoid liability, an employer must provide its
    employees with full and timely meal periods whenever those
    meal periods are required.
    The practice of rounding time punches for meal periods is
    inconsistent with the purpose of the Labor Code provisions and
    the IWC wage order. The text of Labor Code section 512 and
    Wage Order No. 4 sets precise time requirements for meal
    periods. Each meal period must be “not less than 30 minutes,”
    and no employee shall work “more than five hours per day” or
    “more than 10 hours per day” without being provided with a
    meal period. (Lab. Code, § 512, subd. (a); accord, Wage Order
    No. 4, § 11(A) [“No employer shall employ any person for a work
    period of more than five (5) hours without a meal period of not
    less than 30 minutes . . . .”]; see Brinker, 
    supra,
     53 Cal.4th at
    p. 1041.) These provisions speak directly to the calculation of
    time for meal period purposes.
    The precision of the time requirements set out in Labor
    Code section 512 and Wage Order No. 4 — “not less than 30
    minutes” and “five hours per day” or “ten hours per day” — is at
    odds with the imprecise calculations that rounding involves.
    The regulatory scheme that encompasses the meal period
    provisions is concerned with small amounts of time. (Troester v.
    Starbucks Corp. (2018) 
    5 Cal.5th 829
    , 844 (Troester).) For
    example, we have “requir[ed] strict adherence to” the Labor
    12
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    Code’s requirement that employees receive two daily 10-minute
    rest periods and “scrupulously guarded against encroachments
    on” these periods. (Ibid.) The same vigilance is warranted here.
    Given the relatively short length of a 30-minute meal period, the
    potential incursion that might result from rounding is
    significant. (See Kaanaana v. Barrett Business Services, Inc.
    (2018) 
    29 Cal.App.5th 778
    , 801 (Kaanaana) [“ ‘On a 30-minute
    break, time is scarce’ ” and “ ‘[w]hen time is scarce, minutes
    count.’ ”], review granted Feb. 27, 2019, S253458.)
    Consider, for example, an employee who is provided with
    a 21-minute lunch from 12:04 p.m. to 12:25 p.m. Under AMN’s
    timekeeping system, which rounded time punches to the nearest
    10-minute increment, the lunch would have been recorded as a
    30-minute lunch from 12:00 p.m. to 12:30 p.m. In that scenario,
    an employee would have lost nine of the 30 minutes — or almost
    a third of the time — to which he or she was entitled, and Team
    Time would not have flagged the lunch as a meal period
    violation. Small rounding errors can amount to a significant
    infringement on an employee’s right to a 30-minute meal period.
    The premium pay structure under Labor Code section
    226.7 and Wage Order No. 4 confirms that rounding is
    inappropriate in the meal period context. In general, premium
    pay serves the dual purposes of compensating employees for
    their injuries and incentivizing employers to comply with labor
    standards. (Murphy v. Kenneth Cole Productions, Inc. (2007) 
    40 Cal.4th 1094
    , 1110 (Murphy).) In the meal period context, an
    employee receives the full amount of premium pay — one
    additional hour of pay at the employee’s regular rate of
    compensation for each workday that the meal period is not
    provided — regardless of the extent of the violation. (Lab. Code,
    § 226.7, subd. (c); Wage Order No. 4, § 11(B).) In other words,
    13
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    whether an employer provides a shortened meal period or no
    meal period at all, the employee receives one additional hour of
    pay.
    The premise of this approach is that even relatively minor
    infringements on meal periods can cause substantial burdens to
    the employee. Forcing employees to work through their meal
    periods not only causes economic burdens in the form of extra
    work but also noneconomic burdens on the employees’ health,
    safety, and well-being. (Murphy, 
    supra,
     40 Cal.4th at p. 1113.)
    Employees denied compliant meal periods “face greater risk of
    work-related accidents and increased stress” and lose valuable
    time “free from employer control that is often needed to be able
    to accomplish important personal tasks.” (Ibid.) Shortening or
    delaying a meal period by even a few minutes may exacerbate
    risks associated with stress or fatigue, especially for workers
    who are on their feet most of the day or who perform manual
    labor or repetitive tasks.      Further, within a 30-minute
    timeframe, a few minutes can make a significant difference
    when it comes to eating an unhurried meal, scheduling a
    doctor’s appointment, giving instructions to a babysitter,
    refreshing oneself with a cup of coffee, or simply resting before
    going back to work.
    By requiring premium pay for any violation, no matter
    how minor, the structure makes clear that employers must
    provide compliant meal periods whenever such a period is
    triggered. This corroborates the conclusion that rounding is
    improper here. A premium pay scheme that discourages
    employers from infringing on meal periods by even a few
    minutes cannot be reconciled with a policy that counts those
    minutes as negligible rounding errors.
    14
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    Legislative history supports this understanding. “Meal
    and rest periods have long been viewed as part of the remedial
    worker protection framework. . . . Concerned with the health
    and welfare of employees, the IWC issued wage orders
    mandating the provision of meal and rest periods in 1916 and
    1932, respectively. . . . The wage orders required meal and rest
    periods after specified hours of work. The only remedy available
    to employees, however, was injunctive relief aimed at
    preventing future abuse. In 2000, due to a lack of employer
    compliance, the IWC added a pay remedy to the wage orders,
    providing that employers who fail to provide a meal or rest
    period ‘shall pay the employee one (1) hour of pay at the
    employee’s regular rate of compensation for each work day’ that
    the period is not provided.” (Murphy, supra, 40 Cal.4th at
    pp. 1105–1106, citations omitted.) Around the same time, the
    Legislature “wrote into statute various guarantees that
    previously had been left to the IWC, including meal break
    guarantees.” (Brinker, 
    supra,
     53 Cal.4th at pp. 1037–1038.)
    The legislative history indicates that the meal period
    provisions are not “aimed at protecting or providing employees’
    wages. Instead, [they are] primarily concerned with ensuring
    the health and welfare of employees by requiring that employers
    provide meal . . . periods as mandated by the IWC.” (Kirby v.
    Immoos Fire Protection, Inc. (2012) 
    53 Cal.4th 1244
    , 1255.) As
    Donohue argues, the health and safety concerns underlying
    these provisions distinguish the meal period context from the
    wage calculation context, in which the practice of rounding time
    punches was developed. For purposes of calculating wages,
    counting slightly fewer minutes one day can be made up by
    counting a few more minutes another day. But the same is not
    true for meal periods. Under the applicable statute and wage
    15
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    order, a shorter or delayed meal period one day cannot be offset
    by a longer or earlier meal period another day. The premium
    pay scheme reflects the Legislature’s and the IWC’s
    determination that infringements on meal period requirements
    threaten employees’ health and safety whenever they occur
    (Murphy, supra, 40 Cal.4th at p. 1113; Kaanaana, supra, 29
    Cal.App.5th at p. 801, rev.gr.), and the scheme was enacted to
    address inadequate employer compliance (Murphy, at pp. 1105–
    1106). Rounding policies are at odds with the requirement that
    employers pay the full premium wage for meal period violations.
    When the actual times that an employee must work during a
    day reveal a meal period violation, the violation cannot be
    papered over by rounding.
    This understanding also comports with the remedial
    purpose of the Labor Code and wage orders. “Because the laws
    authorizing the regulation of wages, hours, and working
    conditions are remedial in nature, courts construe these
    provisions liberally, with an eye to promoting the worker
    protections they were intended to provide.” (Prachasaisoradej
    v. Ralphs Grocery Co., Inc. (2007) 
    42 Cal.4th 217
    , 227.) As we
    have explained, rounding is incompatible with promoting strict
    adherence to the safeguards for workers’ health, safety, and
    well-being that meal periods are intended to provide.
    The Court of Appeal here relied on See’s Candy Shops, Inc.
    v. Superior Court (2012) 
    210 Cal.App.4th 889
     (See’s Candy I).
    See’s Candy I concluded that employers may use rounded time
    punches to calculate regular and overtime wages if the rounding
    policy is neutral on its face and as applied. (Id. at p. 907.) That
    court consulted a federal regulation under the Fair Labor
    Standards Act of 1938 that addresses rounding practices. (
    29 C.F.R. § 785.48
    (b) (2020).) The regulation, first promulgated in
    16
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    1961, states: “It has been found that in some industries,
    particularly where time clocks are used, there has been the
    practice for many years of recording the employees’ starting
    time and stopping time to the nearest 5 minutes, or to the
    nearest one-tenth or quarter of an hour. Presumably, this
    arrangement averages out so that the employees are fully
    compensated for all the time they actually work.                For
    enforcement purposes this practice of computing working time
    will be accepted, provided that it is used in such a manner that
    it will not result, over a period of time, in failure to compensate
    the employees properly for all the time they have actually
    worked.” (Ibid.)
    Federal courts had interpreted the regulation to permit
    rounding policies as long as they “on average, favor[] neither
    overpayment nor underpayment” and do not “ ‘consistently
    result[] in a failure to pay employees for time worked.’ ” (Alonzo
    v. Maximus, Inc. (C.D.Cal. 2011) 
    832 F.Supp.2d 1122
    , 1126.)
    Conversely, rounding policies violate the regulation if they
    “systematically undercompensate employees” (id. at pp. 1126–
    1127), such as when the rounding policy “encompasses only
    rounding down” (Eyles v. Uline, Inc. (N.D.Tex., Sept. 4, 2009,
    No. 4:08-CV-577-A) 
    2009 WL 2868447
    , p. *4).
    The See’s Candy I court observed that the Division of
    Labor Standards Enforcement (DLSE), the agency that enforces
    California’s labor laws, had adopted the federal regulation in its
    manual. (See’s Candy I, supra, 210 Cal.App.4th at p. 902; see
    ibid. [DLSE Manual is not binding but may be considered for its
    persuasive value].) The court then concluded it was appropriate
    to adopt the federal regulatory standard: “Assuming a
    rounding-over-time policy is neutral, both facially and as
    applied, the practice is proper under California law because its
    17
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    net effect is to permit employers to efficiently calculate hours
    worked without imposing any burden on employees.” (See’s
    Candy I, supra, 210 Cal.App.4th at p. 903.) The court observed
    that employers across the country have long used rounding and
    it would be unreasonable to prevent California employers from
    doing the same. (Ibid.) The court held that an employer is
    entitled to use a rounding policy if it “is fair and neutral on its
    face and ‘it is used in such a manner that it will not result, over
    a period of time, in failure to compensate the employees properly
    for all the time they have actually worked.’ ” (Id. at p. 907.)
    The See’s Candy I court believed this rounding standard is
    consistent with Labor Code section 204, subdivision (a), which
    provides: “All wages . . . earned by any person in any
    employment are due and payable twice during each calendar
    month, on days designated in advance by the employer as the
    regular paydays.” According to the court, the focus of section
    204 is on the timing of wage payments, not the way those wages
    are calculated. (See’s Candy I, supra, 210 Cal.App.4th at
    pp. 904–905.) In addition, the court observed that the phrase
    “all wages” does not necessarily refer to an amount calculated
    on the basis of unrounded time punches. (Id. at p. 905
    [“Fundamentally, the question whether all wages have been
    paid is different from the issue of how an employer calculates
    the number of hours worked and thus what wages are owed.
    Section 204 does not address the measurement issue.”].) Thus,
    the court concluded, the phrase “all wages” in section 204 does
    not bar the practice of rounding time punches.
    Further, See’s Candy I held that rounding is consistent
    with Labor Code section 510, subdivision (a), which provides:
    “Any work in excess of eight hours in one workday and any work
    in excess of 40 hours in any one workweek . . . shall be
    18
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    compensated at the rate of no less than one and one-half times
    the regular rate of pay for an employee.” The court said the
    provision “sets the multiplier for the rate at which ‘[a]ny’
    overtime work must be paid” and “has nothing to do with
    rounding or calculating time.” (See’s Candy I, supra, 210
    Cal.App.4th at p. 905.) The court also rejected the argument
    that rounding can never be neutral because California law
    requires the compensation rate to increase after eight hours of
    work a day. (Id. at pp. 905–906.) Ultimately, the court said,
    whether California’s overtime rules render a rounding policy
    unfair is a factual, not legal, issue. (Id. at p. 906.)
    Since See’s Candy I was decided, state and federal courts
    have applied its standard to determine whether various
    rounding policies are valid under California law. (See, e.g.,
    David v. Queen of Valley Medical Center (2020) 
    51 Cal.App.5th 653
    , 664; AHMC Healthcare, Inc. v. Superior Court (2018) 
    24 Cal.App.5th 1014
    , 1027–1028; Utne v. Home Depot U.S.A., Inc.
    (2017) (N.D.Cal. Dec. 4, 2017, No. 16-cv-01854-RS) 
    2017 WL 5991863
    , pp. *2–*3.) This court has never decided the validity
    of the rounding standard articulated in See’s Candy I, and we
    are not asked to do so here.
    But even assuming the validity of See’s Candy I, a
    rounding policy in the meal period context does not comport with
    its neutrality standard. As noted, failing to provide employees
    with full and timely meal periods burdens their health, safety,
    and well-being by aggravating risks associated with stress or
    fatigue. By deeming delayed or shortened meal breaks as
    “timely” and “complete” when they are not, a rounding policy
    erodes the health and safety protections that the meal period
    requirements are intended to achieve. (See Murphy, 
    supra,
     40
    Cal.4th at p. 1113.) Moreover, in articulating its standard, See’s
    19
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    Candy I reasoned that the rounding policy “ ‘averages out’ ” and
    “employees are fully compensated ‘over a period of time.’ ” (See’s
    Candy I, supra, 210 Cal.App.4th at p. 901.) In the meal period
    context, however, there is an asymmetry between the treatment
    of rounded-up minutes (i.e., time not worked that is
    compensated with regular pay) and the treatment of rounded-
    down minutes (i.e., time worked that may trigger premium pay).
    As noted, under AMN’s policy, a 21-minute lunch from
    12:04 p.m. to 12:25 p.m. would be recorded as a 30-minute lunch
    from 12:00 p.m. to 12:30 p.m. Meanwhile, a 38-minute lunch
    from 11:55 a.m. to 12:33 p.m. would be recorded as a 30-minute
    lunch from 12:00 p.m. to 12:30 p.m. This means that the
    rounding policy, while never triggering premium pay for
    compliant meal periods, does not always trigger premium pay
    for noncompliant meal periods. The same concern applies to the
    timing of meal periods; the policy never triggers premium pay
    for early or on-time meal periods, but it does not always trigger
    premium pay for meal periods that are improperly delayed.
    AMN argues that its rounding policy was neutral over
    time because it sometimes paid employees for a few extra
    minutes that they did not work and sometimes did not pay them
    for a few minutes that they did work. AMN asserts that the
    policy slightly overcompensated the class as a whole. But this
    argument does not properly account for the underpayment of
    premium pay. It is true that in the 38-minute lunch example
    above, the rounding policy would count the extra eight minutes
    of lunch as work time and would trigger regular pay for those
    eight minutes. But in the 21-minute lunch example, the
    rounding policy does not trigger the “one additional hour of
    [regular] pay” (Lab. Code, § 226.7, subd. (c); Wage Order No. 4,
    § 11(B)) that the employee is owed. In this respect, the rounding
    20
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    policy is not neutral. It never provides employees with premium
    pay when such pay is not owed, but it does not always trigger
    premium pay when such pay is owed.
    We recognize that rounding was developed as a means of
    “efficiently calculat[ing] hours worked” and wages owed to
    employees (See’s Candy I, supra, 210 Cal.App.4th at p. 903) and
    is useful “in some industries, particularly where time clocks are
    used” (
    29 C.F.R. § 785.48
    (b) (2020)). But technological advances
    may help employers to track time more precisely, and
    “employers are in a better position than employees to devise
    alternatives.” (Troester, supra, 5 Cal.5th at p. 848.) In this case,
    AMN was already using an electronic timekeeping system,
    Team Time, that recorded employees’ unrounded time punches.
    The system could have kept track of potentially noncompliant
    meal periods using those unrounded time punches instead of
    rounding the punches to the nearest 10-minute increment. As
    Donohue observes, Team Time actually had to take the extra
    step of converting the unrounded time punches to rounded ones;
    it is not clear what efficiencies were gained from this practice.
    AMN eventually switched to a new timekeeping system that
    does not round time punches after this lawsuit was filed. As
    technology continues to evolve, the practical advantages of
    rounding policies may diminish further.
    III.
    We now consider whether time records showing
    noncompliant meal periods raise a rebuttable presumption of
    meal period violations at summary judgment. We hold they do.
    This rebuttable presumption was first discussed in Justice
    Werdegar’s concurrence in Brinker: “Employers covered by
    Industrial Welfare Commission (IWC) wage order No. 5-2001
    21
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    (Cal. Code Regs., tit. 8, § 11050) have an obligation both to
    relieve their employees for at least one meal period for shifts
    over five hours (id., subd. 11(A)) and to record having done so
    (id., subd. 7(A)(3) [‘Meal periods . . . shall also be recorded.’]). If
    an employer’s records show no meal period for a given shift over
    five hours, a rebuttable presumption arises that the employee
    was not relieved of duty and no meal period was provided. This
    is consistent with the policy underlying the meal period
    recording requirement, which was inserted in the IWC’s various
    wage orders to permit enforcement. (See, e.g., IWC board for
    wage order No. 7-63 meeting mins. (Dec. 14–15, 1966) pp. 4–5
    [rejecting proposal to eliminate the meal period recording
    requirement because ‘without the recording of all in-and-out
    time, including meal periods, the enforcement staff would be
    unable to adequately investigate and enforce’ a wage order’s
    meal period provisions].) An employer’s assertion that it did
    relieve the employee of duty, but the employee waived the
    opportunity to have a work-free break, is not an element that a
    plaintiff must disprove as part of the plaintiff’s case-in-chief.
    Rather, . . . the assertion is an affirmative defense, and thus the
    burden is on the employer, as the party asserting waiver, to
    plead and prove it.” (Brinker, supra, 53 Cal.4th at pp. 1052–
    1053 (conc. opn. of Werdegar, J.).)
    Justice Werdegar added: “As the Division of Labor
    Standards Enforcement (DLSE) has explained, even under the
    less restrictive wage order applicable to agricultural employees,
    if ‘a meal period is not taken by the employee, the burden is on
    the employer to show that the agricultural employee had been
    advised of his or her legal right to take a meal period and has
    knowingly and voluntarily decided not to take the meal period.
    Again, we emphasize, the burden is on the employer.’ (Dept.
    22
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    Industrial Relations, DLSE Opn. Letter No. 2003.08.13 (Aug.
    13, 2003) p. 2 [interpreting IWC wage order No. 14 (Cal. Code
    Regs., tit. 8, § 11140)].) To place the burden elsewhere would
    offer an employer an incentive to avoid its recording duty and a
    potential windfall from the failure to record meal periods. Both
    the United States Supreme Court and the courts of this state
    have rejected such an approach. (See Anderson v. Mt. Clemens
    Pottery Co. (1946) 
    328 U.S. 680
    , 686–688 [where an employer is
    subject to a recordkeeping requirement, the burden shifts to
    that employer to rebut employee proof of monies owed once a
    prima facie case has been made]; Ghazaryan v. Diva Limousine,
    Ltd. (2008) 
    169 Cal.App.4th 1524
    , 1536, fn. 11 [refusing to allow
    an employer to use any shortcomings in its records to resist
    employee wage claims]; Cicairos v. Summit Logistics, Inc. (2005)
    
    133 Cal.App.4th 949
    , 961 [‘ “[W]here the employer has failed to
    keep records required by statute, the consequences for such
    failure should fall on the employer, not the employee.” ’].)”
    (Brinker, 
    supra,
     53 Cal.4th at p. 1053, fn. 1 (conc. opn. of
    Werdegar, J.).)
    The term “waiver,” as Justice Werdegar used it, should not
    be confused with the “waived” meal period that Labor Code
    section 512, subdivision (a), authorizes only under limited
    circumstances. We understand an employee’s “waiver” in this
    context in the colloquial sense that the employee chose to work
    when he or she was not required. We do not suggest that
    employees have the unilateral option — without regard for the
    waiver requirements in Labor Code section 512,
    subdivision (a) — to waive their employer’s obligation to relieve
    them from duty and from employer control for a 30-minute meal
    period within the required timeframe. (See Brinker, 
    supra,
     53
    Cal.4th at pp. 1039–1040 & fn. 19.)
    23
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    After Brinker, various Courts of Appeal have cited
    approvingly to Justice Werdegar’s analysis of the rebuttable
    presumption issue. (See, e.g., Carrington v. Starbucks Corp.
    (2018) 
    30 Cal.App.5th 504
    , 527; ABM Industries Overtime Cases
    (2017) 
    19 Cal.App.5th 277
    , 311; Lubin v. Wackenhut Corp.
    (2016) 
    5 Cal.App.5th 926
    , 951; Safeway, Inc. v. Superior Court
    (2015) 
    238 Cal.App.4th 1138
    , 1159–1160; Bradley v. Networkers
    Internat., LLC (2012) 
    211 Cal.App.4th 1129
    , 1144–1145.) We
    now adopt her discussion of the rebuttable presumption in full.
    As Justice Werdegar explained, an employer’s assertion
    that an employee waived a meal period “is not an element that
    a plaintiff must disprove as part of the plaintiff’s case-in-chief.”
    (Brinker, 
    supra,
     53 Cal.4th at p. 1053 (conc. opn. of Werdegar,
    J.).) Instead, the assertion is “an affirmative defense,” and “the
    burden is on the employer, as the party asserting waiver, to
    plead and prove it.” (Ibid.) The “plaintiff’s case-in-chief” and
    the “affirmative defense” refer to the merits of the case.
    Contrary to AMN’s argument, the presumption goes to the
    question of liability and applies at the summary judgment stage,
    not just at the class certification stage.
    Moreover, AMN is incorrect that the presumption applies
    only to records showing missed meal periods; the presumption
    applies to records showing short and delayed meal periods as
    well. Providing employees with short or delayed meal periods is
    just as much a violation of the meal period provisions as failing
    to provide employees with a meal period at all.
    The rationale underlying the rebuttable presumption
    supports these conclusions. The presumption derives from an
    employer’s duty to maintain accurate records of meal periods.
    (Brinker, supra, 53 Cal.4th at p. 1053 (conc. opn. of Werdegar,
    24
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    J.); Wage Order No. 4, § 7(A)(3) [“Every employer shall keep
    accurate information with respect to each employee . . . . [¶] . . .
    [¶] . . . Meal periods . . . shall also be recorded.”].) It is
    important that employers keep accurate records so that
    enforcement agencies can “ ‘adequately investigate and enforce’
    a wage order’s meal period provisions.” (Brinker, at p. 1053
    (conc. opn. of Werdegar, J.).) Because time records are required
    to be accurate, it makes sense to apply a rebuttable presumption
    of liability when records show noncompliant meal periods. If the
    records are accurate, then the records reflect an employer’s true
    liability; applying the presumption would not adversely affect
    an employer that has complied with meal period requirements
    and has maintained accurate records. If the records are
    incomplete or inaccurate — for example, the records do not
    clearly indicate whether the employee chose to work during
    meal periods despite bona fide relief from duty — then the
    employer can offer evidence to rebut the presumption. It is
    appropriate to place the burden on the employer to plead and
    prove, as an affirmative defense, that it genuinely relieved
    employees from duty during meal periods. (Ibid.) “To place the
    burden elsewhere would offer an employer an incentive to avoid
    its recording duty and a potential windfall from the failure to
    record meal periods.” (Id. at p. 1053, fn. 1.) “ ‘ “[W]here the
    employer has failed to keep records required by statute, the
    consequences for such failure should fall on the employer, not
    the employee.” ’ ” (Ibid.)
    In addition, we reject AMN’s argument that applying the
    presumption at the summary judgment stage would eviscerate
    the rule that employers need not police meal periods. In
    Brinker, we said that an “employer satisfies [meal period]
    obligation[s] if it relieves its employees of all duty, relinquishes
    25
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    control over their activities and permits them a reasonable
    opportunity to take an uninterrupted 30-minute break, and does
    not impede or discourage them from doing so. . . . [¶] . . . [T]he
    employer is not obligated to police meal breaks and ensure no
    work thereafter is performed. Bona fide relief from duty and the
    relinquishing of control satisfies the employer’s obligations, and
    work by a relieved employee during a meal break does not
    thereby place the employer in violation of its obligations and
    create liability for premium pay . . . .” (Brinker, 
    supra,
     53
    Cal.4th at pp. 1040–1041.) In AMN’s view, applying the
    presumption at the summary judgment stage means that time
    records showing missed, short, or delayed meal periods create
    “automatic liability” for employers. According to AMN, this
    would leave employers with two options for avoiding liability:
    Employers could monitor every meal period and ensure no work
    is performed, or employers could eliminate flexible meal period
    policies and punish employees for choosing to work during
    scheduled meal periods.          AMN says both options are
    inconsistent with Brinker, which does not require employers to
    police meal periods and allows employees to voluntarily work
    during meal periods.
    AMN misunderstands how the rebuttable presumption
    operates at the summary judgment stage. Applying the
    presumption does not mean that time records showing missed,
    short, or delayed meal periods result in “automatic liability” for
    employers. If time records show missed, short, or delayed meal
    periods with no indication of proper compensation, then a
    rebuttable presumption arises. Employers can rebut the
    presumption by presenting evidence that employees were
    compensated for noncompliant meal periods or that they had in
    fact been provided compliant meal periods during which they
    26
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    chose to work.        “Representative testimony, surveys, and
    statistical analysis,” along with other types of evidence, “are
    available as tools to render manageable determinations of the
    extent of liability.” (Brinker, 
    supra,
     53 Cal.4th at p. 1054 (conc.
    opn. of Werdegar, J.).) Altogether, this evidence presented at
    summary judgment may reveal that there are no triable issues
    of material fact. The rebuttable presumption does not require
    employers to police meal periods. Instead, it requires employers
    to give employees a mechanism for recording their meal periods
    and to ensure that employees use the mechanism properly.
    The court in Silva v. See’s Candy Shops, Inc. (2016) 
    7 Cal.App.5th 235
    , 253–254 (See’s Candy II) concluded that the
    rebuttable presumption is inapplicable when reviewing a
    motion for summary judgment as opposed to a motion for class
    certification. Similarly, the court in Serrano v. Aerotek, Inc.
    (2018) 
    21 Cal.App.5th 773
     “specifically reject[ed] [the plaintiff’s]
    contention that ‘time records show[ing] late and missed meal
    periods creat[ed] a presumption of violations,’ ” even though
    that plaintiff’s time records had shown “that on several days on
    which she worked more than six hours, she took her meal breaks
    more than five hours after beginning work or, in a couple of
    instances, did not take a meal break at all.” (Id. at pp. 781, 778.)
    We disapprove Silva v. See’s Candy Shops, Inc., supra, 
    7 Cal.App.5th 235
    , and Serrano v. Aerotek, Inc., supra, 
    21 Cal.App.5th 773
    , to the extent they are inconsistent with this
    opinion.
    We reiterate the rules set forth in Brinker: An employer
    is liable only if it does not provide an employee with the
    opportunity to take a compliant meal period. The employer is
    not liable if the employee chooses to take a short or delayed meal
    period or no meal period at all. The employer is not required to
    27
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    police meal periods to make sure no work is performed. Instead,
    the employer’s duty is to ensure that it provides the employee
    with bona fide relief from duty and that this is accurately
    reflected in the employer’s time records. Otherwise, the
    employer must pay the employee premium wages for any
    noncompliant meal period. (See Brinker, 
    supra,
     53 Cal.4th at
    pp. 1040–1041.) If time records show noncompliant meal
    periods, then a rebuttable presumption of liability arises. This
    presumption applies at the summary judgment stage, and the
    employer may rebut the presumption with evidence of bona fide
    relief from duty or proper compensation. Employers may use a
    timekeeping system like Team Time to track meal period
    violations as long as the system does not round time punches.
    Team Time included a dropdown menu for employees to indicate
    whether they were provided a compliant meal period but chose
    to work, and the system triggered premium pay for any missed,
    short, or delayed meal periods due to the employer’s
    noncompliance. Thus, Team Time would have ensured accurate
    tracking of meal period violations if it had simply omitted
    rounding.
    IV.
    We now apply our holdings to the facts of this case. We
    conclude that AMN improperly used rounded time punches to
    track potentially noncompliant meal periods. Before September
    2012, when Team Time records showed a missed meal period or
    a meal period that was shorter than 30 minutes or taken after
    five hours of work, AMN assumed a meal period violation and
    paid the employee a premium wage. This system may have
    resulted in some overcompensation because AMN gave
    employees premium pay regardless of whether they voluntarily
    chose to work during an off-duty meal period. But this system
    28
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    did not properly account for meal periods that were short or
    delayed based on actual time punches but did not appear as
    short or delayed under the rounding policy. AMN would be
    liable for premium pay for any instances in which employees did
    not voluntarily choose to shorten or delay those meal periods.
    After September 2012, when an employee recorded a
    missed, short, or delayed meal period, a dropdown menu
    appeared on Team Time. The dropdown menu prompted the
    employee to choose one of three options: (1) “I was provided an
    opportunity to take a 30 min break before the end of my 5th hour
    of work but chose not to”; (2) “I was provided an opportunity to
    take a 30 min break before the end of my 5th hour of work but
    chose to take a shorter/later break”; (3) “I was not provided an
    opportunity to take a 30 min break before the end of my 5th hour
    of work.” This system also did not properly account for meal
    periods that were short or delayed based on unrounded as
    opposed to rounded time punches. The dropdown menu did not
    appear for such meal periods. If any of those meal periods were
    not voluntarily shortened or delayed, then AMN would be liable
    for premium pay.
    The Court of Appeal reached the opposite conclusion as to
    the rounding policy before and after September 2012 and ruled
    in favor of AMN. We reverse the Court of Appeal’s judgment as
    to the meal period claim and remand with directions to remand
    the matter to the trial court to permit either party to file a new
    summary adjudication motion as to the meal period claim. (See
    TRB Investments, 
    supra,
     40 Cal.4th at pp. 23, 31–32.) Because
    the parties did not have the benefit of this decision when
    litigating the defendant’s summary judgment motion and the
    plaintiff’s summary adjudication motion, they should now be
    afforded another opportunity to present relevant evidence
    29
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    concerning AMN’s compliance with Brinker. As to the meal
    periods that are short or delayed based on unrounded time
    punches and for which no premium wages were paid, did the
    employees voluntarily choose to take short or delayed meal
    periods? On remand, the parties will have the opportunity to
    present evidence bearing on this question.
    We provide some guidance on how the rebuttable
    presumption should be applied on remand in light of the usual
    summary adjudication standards. According to Donohue’s
    expert witness, AMN’s time records showed 40,110 short meal
    periods and 6,651 delayed meal periods for which premium
    wages were not paid; these meal periods did not show up as
    short or delayed in AMN’s timekeeping system because of
    rounding. The introduction of these time records by either party
    would trigger the rebuttable presumption. If AMN renews its
    motion for summary adjudication, it must satisfy the initial
    burden of production and make a prima facie showing that “one
    or more elements of the cause of action . . . cannot be
    established, or that there is a complete defense to the cause of
    action.” (Code Civ. Proc., § 437c, subd. (p)(2).) To satisfy this
    burden, AMN could try to establish the defense that it genuinely
    relieved employees from duty during meal periods. Specifically,
    to rebut the presumption of noncompliance arising from the
    time records, AMN would need to provide evidence that
    employees voluntarily chose to work during off-duty meal
    periods that appear in time records to be short or delayed based
    on unrounded time punches. If AMN satisfies this burden, then
    the burden of production shifts to Donohue “to show that a
    triable issue of one or more material facts exists as to the cause
    of action or a defense.” (Ibid.) But the ultimate burden of
    persuasion remains with the defendant to show that no genuine
    30
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    issue of material fact exists and that it is entitled to judgment
    as a matter of law.
    Conversely, when a plaintiff moves for summary
    adjudication, the plaintiff meets “his or her burden of showing
    that there is no defense to a cause of action” if the plaintiff
    “prove[s] each element of the cause of action entitling the party
    to judgment on the cause of action.” (Code Civ. Proc., § 437c,
    subd. (p)(1).) Donohue can satisfy that burden by using time
    records to raise a rebuttable presumption of meal period
    violations. Once the plaintiff meets that burden, the burden
    shifts to the defendant “to show that a triable issue of one or
    more material facts exists as to the cause of action or a defense.”
    (Ibid.) But the plaintiff bears the ultimate burden of persuasion
    to show that no genuine issue of material fact exists and that it
    is entitled to judgment as a matter of law. The parties may
    present new evidence and arguments to address these issues on
    remand.
    According to AMN, it has already established that the
    time records do not raise a rebuttable presumption of meal
    period violations. AMN argues that Donohue never used Team
    Time’s dropdown menu to indicate that she was not provided
    with a compliant meal period, which suggests that she was
    never denied a compliant meal period. But because the
    dropdown menu was triggered by rounded time punches, this
    evidence does not encompass all meal periods that were short or
    delayed based on actual time punches. Thus, AMN cannot rely
    on this evidence to prove that there were no meal period
    violations.
    AMN also contends that the biweekly certifications signed
    by Donohue and other class members show that there were no
    31
    DONOHUE v. AMN SERVICES, LLC
    Opinion of the Court by Liu, J.
    meal period violations. Those certifications stated: “I was
    provided the opportunity to take all meal breaks to which I was
    entitled, or, if not, I have reported on this timesheet that I was
    not provided the opportunity to take all such meal breaks.”
    Donohue argues that AMN cannot rely on the certifications to
    prove that there were no meal period violations. Because the
    Team Time dropdown menu was triggered by rounded time
    punches, the system did not flag meal periods that were short or
    delayed based on unrounded as opposed to rounded time
    punches. As a result, Donohue contends, employees would not
    have known about the potentially noncompliant meal periods
    that Team Time did not flag unless they kept their own time
    records. According to Donohue, Team Time thus led to the
    systematic underreporting of noncompliant meal periods and
    caused the biweekly certifications to be inaccurate. In addition,
    Donohue argues that the significance of the certifications should
    be discounted because employees had to sign them to get paid.
    We leave these issues for the parties and the trial court to
    address on remand. We note that if, as Donohue contends,
    employees would not have known about potentially
    noncompliant meal periods that Team Time did not flag unless
    they kept their own time records, then the certifications would
    be inaccurate and cannot be used to prove that there were no
    meal period violations. It is the employer’s duty to maintain
    accurate time records; the law does not expect or require
    employees to keep their own time records to uncover potential
    meal period violations. (Wage Order No. 4, § 7(A)(3).)
