    No. 20-50474
    Plaintiff-Appellant Ricky Danell Lockhart appeals the district court’s
    grant of summary judgment in favor of his former employer, Defendant-
    Appellee Republic Services, Inc. (“Republic”). Lockhart has raised no
    genuine issues of material fact with respect to either his claims of racial
    discrimination under Title VII of the Civil Rights Act of 1964 (“Title VII”)
    or overtime violations and retaliation under the Fair Labor Standards Act
    (“FLSA”), so we affirm.
    I. BACKGROUND
    Ricky Danell Lockhart, an African American man, worked for
    Republic as a roll-off driver before being fired in November 2017. In that job,
    he provided waste removal service to Republic’s customers in San Antonio,
    Texas. Republic’s drivers were paid on a piece-rate basis, also known as “can
    pay,” which was computed weekly by multiplying the individual driver’s
    personal “can rate” (determined by that driver’s experience and seniority)
    by each haul’s “can value” (based on the location of the can, its distance
    from the landfill, and the difficulty of the haul). 1 Can values were set by
    Republic and communicated to the drivers on a detailed spreadsheet. At the
    end of the day, each driver filled out a route sheet, recording the containers
    he had hauled that day and the values associated with each haul. Drivers also
    clocked in and out of work every day.
    In 2017, Republic General Manager Ryan Whiteside selected
    Lockhart to participate in the 2017 ROAD-EO, an annual event designed to
    showcase the company’s best drivers. At the ROAD-EO in Phoenix, Arizona,
    Lockhart complained to a Republic District Manager about his can pay. Back
    1
    Republic illustrates this payment system as follows: “For example, if Lockhart’s
    can rate was $15 and a particular haul was valued at three cans, Lockhart was paid $45 for
    that haul.”

    No. 20-50474
    in San Antonio, Lockhart discussed his complaint with Whiteside. Lockhart
    believed that he and his colleagues were not being properly compensated for
    each haul they completed because the company classified some hauls as
    container “swaps,” rather than “dump and returns.” A swap occurs when a
    driver travels to a customer’s location with an empty container, exchanges
    the empty container for the full container, and takes the full container to the
    landfill. This trip involves two legs. A dump-and-return involves traveling to
    a customer’s location, picking up and transporting the full container to the
    landfill, and returning the empty container to the customer’s location. This
    trip involves three legs. Because a dump-and-return involves more travel, it
    is compensated at a higher rate. Although Republic predetermined how a
    particular can was to be treated, Lockhart believed that he could be more
    productive if he could decide whether to treat a given haul as a swap or a
    dump-and-return while he was still in the field.
    Shortly after returning from the ROAD-EO, Lockhart was involved in
    four separate disciplinary incidents. Republic uses a progressive discipline
    plan to address employee infractions: The first infraction elicits an oral
    warning; the second a written warning; the third a suspension; the fourth the
    termination of employment. Kenny Ramzinski, Lockhart’s supervisor, orally
    reprimanded Lockhart in April 2017 for recording the incorrect container pay
    on his route sheets. Lockhart next received a warning in June of that year for
    abuse of company equipment, charging him with causing more than $4,000
    in damage to his company-owned vehicle by pushing the truck’s “regen
    button” in excess of forty times. A few months later, Lockhart was suspended
    for (1) discussing his personal vehicle with an on-duty mechanic, (2) refusing
    to wear personal protective equipment as required, and (3) being
    insubordinate to Shop Manager Hilda Juarez. Finally, in November 2017,
    Lockhart was terminated after he entered a landfill through an exit gate, in
    violation of company policy.

    No. 20-50474
    Lockhart filed a discrimination charge with the Equal Employment
    Opportunity Commission, received a Notice of Right to Sue, and filed this
    lawsuit against Republic, BFI Waste Services of Texas, LP, Republic Waste
    Services of Texas, LTD., Allied Waste Systems, Inc., Kenny Ramzinski, and
    Ryan Whiteside (collectively, “Defendants” or “Republic”). Lockhart
    alleged that he had been discriminated against on the basis of race, religion,
    and sex, and retaliated against in violation of Title VII and 42 U.S.C. § 1981.
    He also made claims for overtime violations and retaliation under the FLSA.
    Following the district court’s dismissal of Lockhart’s religion and sex
    discrimination claims, Defendants moved for summary judgment on all
    remaining claims. The court granted the motion and dismissed Lockhart’s
    case. He timely appealed.
    II. APPLICABLE LAW
    Summary judgment grants are reviewed de novo, “applying the same
    legal standards as the district court.” 2 The court of appeals must consider
    “[t]he evidence and inferences from the summary judgment record . . . in
    the light most favorable to the nonmovant.” 3 Summary judgment is
    appropriate only “if the movant shows that there is no genuine dispute as to
    any material fact and the movant is entitled to judgment as a matter of law.” 4
    “A fact is material if it ‘might affect the outcome of the suit,’” and “[a]

    return a verdict for the nonmoving party.’” 5
    III. ANALYSIS
    On appeal, Lockhart contends that the evidence creates genuine
    issues of material fact as to whether he was (1) fired because of his race; (2)
    paid overtime in compliance with the FLSA; and (3) retaliated against for
    complaining of Republic’s refusal to pay him in accordance with the FLSA.
    A. Title VII
    Title VII makes it unlawful for an employer to “discharge any
    individual, or otherwise to discriminate against any individual with respect to
    his compensation, terms, conditions, or privileges of employment, because
    of such individual’s race.” 6 When a claim relies on circumstantial evidence,
    the court applies the burden-shifting framework set forth in McDonnell
    Douglas Corp. v. Green, 
    411 U.S. 792
    , 802 (1973). 7 Under that framework, the
    plaintiff must establish a prima facie case of discrimination. 8 If he does, the
    burden “shifts to the employer to articulate a legitimate, nondiscriminatory
    reason for its actions.” 9 If a legitimate explanation is offered by the employer,
    the plaintiff may nevertheless defeat summary judgment by establishing

    42 U.S.C. § 2000e-2(a)(1). Because Title VII and § 1981 are “parallel causes of
    action” that “require the same proof to establish liability,” Harville v. City of Houston,
    Miss., 
    945 F.3d 870
    , 874 n.10 (5th Cir. 2019) (quotation marks omitted), this opinion
    discusses only Lockhart’s Title VII claim.

    Lockhart concedes that this is not a direct evidence case.

    either that (1) the proffered reason is pretextual or (2) “the employer's
    reason, while true, is not the only reason for its conduct, and another
    ‘motivating factor’ is the plaintiff’s protected characteristic.” 10
    We can decide this case on the basis of pretext, so we assume,
    arguendo, that Lockhart has established a prima facie case of racial
    discrimination. A plaintiff pursuing a racial discrimination claim under
    McDonnell Douglas typically must establish that he “(1) is a member of a
    protected group; (2) was qualified for the position at issue; (3) was discharged
    or suffered some adverse employment action by the employer; and (4) was
    replaced by someone outside his protected group or was treated less favorably
    than other similarly situated employees outside the protected group.” 11
    The vast majority of our cases concerning McDonnell Douglas in a
    racial discrimination context recite the elements in this fashion, but a handful
    of cases employ a broader formulation. For example in Autry v. Fort Bend
    Independent School District, we defined the fourth element as requiring proof
    that the employer “either gave the promotion to someone outside of that
    protected class or otherwise failed to promote the plaintiff because of his race.” 12
    Similarly, in Ebbs v. Folger Coffee Co., we required evidence that the plaintiff
    “was replaced by a person outside the protected class or . . . otherwise that his
    discharge was due to race.” 13 In light of this apparent confusion and the fact

    that “[t]he McDonnell Douglas rule was intended to be a flexible one,” 14
    clarification of the proper legal standard for such claims might be necessary
    in short order. But because we can resolve this case on simpler grounds, we
    decline to do so today.
    Assuming that Lockhart has set forth a prima facie case, Republic
    satisfied its burden of providing a nondiscriminatory reason for Lockhart’s
    termination. It asserted that he was fired in compliance with the company’s
    progressive discipline policy after committing four disciplinary infractions in
    a twelve-month period.
    To rebut Republic’s explanation, Lockhart had to demonstrate that
    the proffered reason was pretextual by showing that the explanation for his
    termination was “false or unworthy of credence.” 15 Such evidence “must be
    enough to support a reasonable inference that the proffered reason is false; a
    mere shadow of doubt is insufficient.” 16 Evidence that a proffered
    explanation is false, coupled with a prima facie case, permits a jury to find
    that intentional discrimination occurred. It does not, however, compel such
    a conclusion in every case: There are cases in which, despite such evidence,
    “no rational factfinder could conclude that the action was discriminatory.” 17

    Lockhart contends that (1) the “highly contested” nature of the
    events leading to his termination and (2) evidence of racial slurs used by
    Republic employees, including his supervisor, Ramzinski, demonstrate that
    Republic’s explanation for his termination was false. We disagree.
    The contested nature of Lockhart’s violations is insufficient to
    establish that his termination was pretextual. Lockhart disputes the
    underlying basis for three of the disciplinary violations he received. He
    stresses, for example, that (1) he never abused his truck’s regen button, (2) it
    was common practice for drivers to speak to mechanics about their personal
    vehicles, and (3) the exit gate to the landfill was not properly marked. But
    Title VII does not allow us to second guess an employer’s reasonable
    business decisions. 18 We have noted that “evidence that the employer’s
    investigation merely came to an incorrect conclusion does not establish a
    racial motivation behind an adverse employment decision. Management does
    not have to make proper decisions, only non-discriminatory ones.” 19
    There is no evidence that Ramzinski did not reasonably believe
    Lockhart had committed these infractions before he was disciplined.
    Ramzinski’s decision to discipline Lockhart was, in all three disputed
    instances, based on the reports of third parties. With respect to the
    equipment abuse incident, it is undisputed that a third-party mechanic
    reported that the regen button had been pushed over forty times and that
    Lockhart had driven that truck on all but five days in the eleven-week period
    preceding the mechanical issue. As to the incidents of insubordination

    reported by Juarez, “[i]n cases in which an employer [disciplines] an
    employee based on the complaint of another employee, the issue is not the
    truth or falsity of the allegation, but ‘whether the employer reasonably
    believed the employee’s allegation and acted on it in good faith.’” 20 The
    same is true of the gate incident. Although it is disputed whether Garza gave
    Lockhart permission to enter the landfill through the exit gate, Ramzinski
    reasonably believed that Lockhart had not received permission to do so and
    relied on Garza’s report of the infraction in disciplining Lockhart. The factual
    dispute regarding Lockhart’s job performance would thus not permit a
    reasonable fact finder to conclude that Republic’s proffered explanation is
    false or unworthy of credence.
    Evidence that Ramzinski used racial slurs to refer to Lockhart requires
    closer attention. Discriminatory remarks can constitute circumstantial
    evidence of pretext if they display discriminatory animus on the part of the
    person responsible for making the adverse employment decision or someone
    with influence over that person. 21
    Citing deposition testimony of former employee Juan Puga, Lockhart
    contends that Ramzinski used a Spanish-language racial slur to refer to
    Lockhart behind his back. 22 Puga testified that Ramzinski used the slur

    22
    Lockhart also contends that Republic was a hostile work environment in which
    racial slurs were commonplace. However, he never raised a hostile work environment
    claim. Therefore, evidence that landfill employees often used racial slurs to refer to him
    and ordered him to dump his haul in dangerous areas of the landfill are irrelevant at this
    juncture.

    “multiple times during the day,” and that “for him it was a joke. It was
    something cool.”
    As an initial matter, we disagree with Republic’s contention that
    Ramzinski’s use of the racial slur did not display racial animus simply because
    he used the term as a joke. The word Ramzinski allegedly used is the Spanish-
    language equivalent to the n-word, which the Ninth Circuit has described as
    “perhaps the most offensive and inflammatory racial slur in English,” 23 and
    “evoking a history of racial violence, brutality, and subordination.” 24
    Because of such words’ history, using them to refer to an individual or group,
    particularly in the employment context, typically will imply discriminatory
    animus on the part of the speaker, regardless of whether the speaker believes
    he uses such words in jest.
    Even though use of this slur is relevant to the pretext inquiry, it is
    nevertheless insufficient to create a genuine issue of fact about the veracity
    of Republic’s proffered explanation. Puga’s testimony about Ramzinski’s use
    of the slur is non-specific in time and context. Neither has Lockhart provided
    evidence that use of the word had any bearing on his termination, especially
    not in contrast to the ample evidence that Lockhart was terminated, pursuant
    to company policy, because he committed four disciplinary violations in a

    twelve-month span. 25 Further, this remark is the only arguable evidence of
    pretext. As such, it is not probative of discriminatory intent under Palasota v.
    Haggar Clothing Co. 26 We conclude that, at best, this evidence creates only a
    “weak issue of fact,” insufficient to overcome the “uncontroverted
    independent evidence that no discrimination had occurred.” 27
    A Title VII plaintiff can also survive summary judgment with evidence
    that race was a motivating factor in the adverse employment decision. 28 It is
    unclear whether Lockhart intends to pursue this theory on appeal. He never
    argued mixed motives to the district court, and his appellate brief is devoid
    of any reference to this theory, save for a single cite to Bostock v. Clayton
    County, Georgia, 29 in support of the idea that the district court impermissibly
    required him to prove that race was “the sole or primary cause” of his
    termination. Typically, Lockhart’s failure to raise the issue in the district
    court would result in the waiver of this argument. 30 However, even if we
    entertained the argument on appeal, such a claim would fare no better than
    Lockhart’s pretext claim. The undisputed evidence indicates that Lockhart
    was terminated in accordance with Republic’s progressive disciplinary
    policy. Nothing in the record suggests that Lockhart’s infractions were
    reported more often or punished more severely than those of other

    that Lockhart’s race had anything to do with his termination.
    B. FLSA
    Lockhart contends that Republic violated the FLSA by failing to
    compensate him properly for overtime hours and by firing him in retaliation
    for making wage-related complaints. We disagree.
    i. Overtime Violations
    The FLSA obligates employers to pay non-exempt employees no less
    than one and a half times their “regular rate” of pay for all overtime hours
    worked, i.e., for all hours worked in excess of forty hours per week. 31 The
    “‘regular rate’ under the Act is a rate per hour,” so when an employee is
    paid on a basis other than hourly, the employee’s “compensation must be
    converted to an hourly rate” before overtime can be properly assessed. 32 The
    “regular rate” for a piece-rate employee like Lockhart “is computed by
    adding together total earnings for the workweek” and dividing that sum by
    “the number of hours worked in the week.” 33
    With respect to piece-rate workers, “[i]n determining the number of
    hours for which overtime compensation is due, all hours worked . . . in a
    particular workweek must be counted.” 34 Although it is unlawful for an
    employer to fail to count and pay an employee for nonproductive hours, such

    as time “spent in waiting . . . [or] time spent in travel on the employer’s
    behalf,” 35 “it is permissible for the parties to agree that the pay the
    employees will earn at piece rates is intended to compensate them for all
    hours worked, the productive as well as the nonproductive hours.” 36
    Lockhart contends that Republic violated overtime laws by
    mischaracterizing the can values associated with particular hauls, which had
    the effect of reducing his overall piece rate and the overtime rate based on it.
    He also claims that his “overtime premium was improperly diluted” by non-
    productive hours spent on the clock.
    As an initial matter, there is no record evidence that Republic
    miscalculated can values in the fashion Lockhart suggests. Contrary evidence
    is clear: Roll-off drivers were given a spreadsheet that indicated the value
    associated with each particular can haul and were instructed to record that
    predetermined value on their route sheets at the end of each day. Although
    Lockhart might believe that the values assigned to particular hauls
    undervalued his work or failed to properly consider the amount of time a
    particular haul took to complete, there is no evidence that Republic paid less
    for a particular can than it had promised.
    Whether Lockhart agreed that his piece rate was intended to
    compensate him for nonproductive time is a more nuanced question. FLSA
    regulations do not specify what is required for the existence of such an
    agreement, and there is little caselaw addressing the matter. However, a
    recently issued guidance letter from the Department of Labor (“DOL”) is
    instructive. In that letter, the DOL explained that it is lawful for an employer
    to use a piece rate system designed to cover both productive and

    No. 20-50474
    nonproductive time, even without a “specific agreement . . . regarding
    the . . . method of computing the regular rate and overtime pay.” 37
    Analogizing to the FLSA’s fluctuating workweek provisions, the DOL
    explained that an agreement requires a “clear and mutual understanding”
    between the parties about the intended compensation, but that such
    understanding “may be inferred from the parties’ conduct.” 38 Further, the
    employees          need     not    “understand[]           the   precise   mathematical
    methodology . . . in how the regular rate is computed.” 39
    The DOL guidance letter relies heavily on Espenscheid v. DirectSat
    USA, LLC, 40 in which the court considered the existence of an agreement by
    reference to the FLSA’s fluctuating workweek provisions. It noted that when
    a fixed salary is intended to compensate an employee for all hours worked in
    a particular week, regardless of the actual number of hours worked, there
    must be a “clear mutual understanding” between the employer and the
    employee regarding what the weekly salary is meant to cover. 41 The court
    reasoned that the existence of an “agreement” with respect to piece rate
    employees mirrored the “clear mutual understanding” requirement, because
    “both [systems] insure [sic] that employees are made aware of methods of
    compensation that depart from the general rules of compensation under the
    FLSA.” 42 Although non-binding, the DOL’s approval of this position is

    persuasive, and we agree that evidence of a “clear mutual understanding”
    between employer and employee may be inferred from the parties’ conduct. 43
    The record demonstrates that (1) Republic’s piece rate system was in-
    tended to compensate roll-off drivers for both their productive and non-pro-
    ductive time, and (2) Lockhart agreed to be compensated in that fashion. It
    is undisputed that Lockhart and his fellow drivers’ piece rates were deter-
    mined by multiplying their personal can rate by each haul’s can value. For
    overtime, Republic calculated each driver’s hourly rate by dividing the total
    weekly earnings by the total hours that driver clocked in that week. All hours
    worked in excess of forty were compensated at one-and-one-half times that
    hourly rate. The daily route sheets did not require drivers to differentiate be-
    tween productive and nonproductive time, and there is no evidence that Re-
    public intended to compensate drivers differently for productive and non-
    productive activities, or communicated as much to its employees.
    The record also reflects that Lockhart agreed to being compensated in
    this manner. For one thing, he testified that, in accepting employment with
    Republic, he agreed to be paid “just on the can rate,” with “no other type of
    pay like hourly pay.” He also accepted payment in this fashion for many years
    before beginning to complain to his supervisors about his pay.
    More importantly, Lockhart’s complaints about the pay structure
    focused not on the productive versus nonproductive time issue, but on the
    value of each can haul. These are two entirely different grievances. He
    expressly complained about how specific hauls were classified as swaps rather
    than dumps-and-returns, believing he could be more productive if he were

    , 717 (4th Cir. 1998))).

    allowed to determine how to treat a particular haul while in the field.
    Ramzinski and others explained the payment system to Lockhart on multiple
    occasions, clarifying why some hauls were coded as they were. And in fact,
    Lockhart testified that, after Republic modified the pay plan in 2017 to
    incorporate his suggestions, he was “real happy” with the adjustment, even
    though he continued to be paid in the exact same fashion as before (i.e., his
    piece rate covering both productive and nonproductive time).
    Neither is there evidence that Republic ever communicated to its
    drivers that they would be paid separately for nonproductive time or that
    Republic ever departed from this payment scheme. However, Lockhart also
    suggests that Serrano v. Republic Services, Inc. 44 demonstrates that there was
    no such agreement here. In Serrano, a group of industrial drivers sued
    Republic for overtime violations. Following a bench trial, the court concluded
    that the drivers had not agreed that their piece rate was meant to compensate
    them for both productive and nonproductive time, citing evidence that (1) no
    one had ever explained the system to the drivers; and (2) when they
    complained about not being paid for non-productive time, they were ignored
    or told that their supervisors would handle the matter. These responses, the
    Serrano court found, “implied a promise of additional compensation or at
    least a matter that was up for negotiation rather than a pay structure that was
    set and agreed to.” 45 Additionally, the Serrano court stressed that Republic’s
    own witnesses took a number of inconsistent positions about the way
    nonproductive time was compensated, including testifying that:
    (1) there is no non-production time in the waste hauling
    business; (2) the only non-production time is sick leave or
    annual leave; (3) Republic does not compensate for down time;

    (4) non-production time is compensated by day rates that are
    applied for down time over four hours in a day or when
    production does not exceed the day rate; and (5) all non-
    production time is included in, and compensated by, the zone
    rates. 46
    This case is different. Here, Republic’s supervisors explained the
    payment structure to Lockhart on multiple occasions in response to his
    confusion, and there is no evidence that the company was ever inconsistent
    in the manner it explained or applied the payment plan.
    Finally, the only indication that Lockhart did not agree to this
    compensation scheme exists in the form of a self-serving declaration that he
    wrote after Republic moved for summary judgment. In that declaration,
    Lockhart asserted that he “never agreed that the can rate was supposed to
    reimburse [him] for both productive and non-productive time.” But nowhere
    in his pleadings did Lockhart make this claim, and his affidavit cannot
    controvert the ample evidence, cited above, indicating that he understood
    and agreed to this payment scheme. Furthermore, his declaration itself belies
    his apparent confusion about the payment scheme. In it, he states:
    [H]ow much I made in overtime was dependent on how much
    the cans I serviced were worth divided by how many hours I
    worked to service those cans. In other words, I was paid based
    on my productivity, not based solely on how many hours I
    worked. The more cans I picked up and/or the less time I took
    to pick them up, the more I made per hour, and therefore the
    more I made in overtime. But not all cans are created equal.
    Considering the foregoing, there is simply no evidence from which a
    reasonable jury could find that Lockhart did not agree to his piece rate
    covering productive and nonproductive time.

    ii. Retaliation
    The FLSA makes it unlawful “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.” 47 To establish a prima facie claim for such
    retaliation, a plaintiff must demonstrate that (1) he participated in an activity
    protected by the FLSA; (2) he suffered an adverse employment action; and
    (3) there exists a causal link between the activity and the adverse action. 48
    “[I]f [Lockhart] cannot prove that he was engaged in protected
    activity . . ., then he cannot make out a viable claim under the FLSA.” 49
    “[A]n informal, internal complaint may constitute protected activity,” 50 as
    may an oral complaint, 51 but “not all ‘abstract grumblings’ or vague
    expressions of discontent are actionable.” 52 To constitute protected activity,
    the informal complaint must “concern some violation of the law” 53 that puts
    the employer on “notice that [the] employee is making a complaint that could
    subject the employer to a later claim of retaliation.” 54

    Lockhart’s informal complaints are not protected by the FLSA. All of
    his complaints to management focused on the value of different can hauls,
    meaning that he was complaining about the amount of his compensation. In
    calling for allowing drivers to determine whether a haul should be treated as
    a swap or as a dump-and-return, Lockhart was advocating for increasing the
    value of his work. He was not suggesting that Republic’s manner of
    calculating the hauls was unlawful. True, a change in the value of a driver’s
    hourly rate would necessarily impact his overtime rate, but that does not
    mean that Lockhart’s complaints were reasonably understood as a challenge
    to the lawfulness of Republic’s compensation scheme. 55 Both Ramzinski and
    Whiteside testified that Lockhart never mentioned overtime pay, but focused
    his complaints only on specific can values, which he believed should have
    been higher. Because Lockhart did not engage in a protected activity under
    the FLSA, summary judgment rejecting this claim was appropriate.

    Based on the foregoing, the judgment of the district court is
    AFFIRMED.
