    Appeal from the United States District Court
    for the Western District of Texas
    (5:06-VCV-236)
    Before GARWOOD, OWEN, and HAYNES, Circuit Judges.
    PER CURIAM:*
    Plaintiffs-appellants, approximately eighty current and former employees
    of defendant-appellee, Boeing Aerospace Operations, Inc., d/b/a Boeing Logistics
    Support Systems (Boeing), appeal the summary judgment dismissal of their
    collective action alleging that Boeing withheld overtime pay in violation of
    section 207 of the Fair Labor Standards Act (FLSA). 
    29 U.S.C. § 207
    . We hold
    *
    Pursuant to 5TH CIR . R. 47.5, the court has determined that this opinion should not
    be published and is not precedent except under the limited circumstances set forth in 5TH
    CIR . R. 47.5.4.
    that opt-in appellants Edward Montelongo and Jesus Lozano have presented
    sufficient evidence to preclude summary judgment, therefore we VACATE and
    REMAND the dismissal of their claims. However, we AFFIRM the district
    court’s dismissal of all other claims.
    I. FACTS AND PROCEEDINGS BELOW
    Appellants were employed at a Boeing facility in San Antonio, Texas
    dedicated to maintaining and repairing military aircraft. Appellants worked as
    mechanics; quality inspectors; “tool control attendants” charged with dispensing
    and inventorying specialized tools from the “tool crib”; and ramp operators
    responsible for ushering aircraft in and out of the facility.
    Boeing used a computer program known as “AutoTime” to monitor
    employee hours and job performance. For attendance purposes, employees were
    required to scan a personalized identification badge at the beginning and end of
    each workday at any of the numerous computers located throughout the facility.1
    Under this system, employees had to “clock in” any time within thirty minutes
    prior to their assigned shift and “clock out” any time within eighteen minutes
    after their shift, but they were only paid for the set number of hours covered by
    their shift. So long as the employees clocked in and out within these “grace
    periods,” AutoTime automatically erased their actual clock-in/out times.
    However, if an employee clocked in before this 30 minute grace period his actual
    clock in time would register in the computer and he would automatically be
    awarded (in addition to his regular shift time) compensable time for the entire
    period between his clock in and the beginning of his regular shift time.
    Similarly, if an employee clocked out after the 18 minute grace period his actual
    1
    Additionally, employees used those same computers to “scan labor,” which required
    them to scan their badges and enter work order numbers at the start and finish of each
    particular task assigned to them.
    2
    clock out time would register in the computer and he would automatically be
    awarded (in addition to his regular shift time) compensable time for the entire
    period between the end of his regular shift time and his clock out. Company
    policy, of which appellants were informed and aware, forbade work without
    overtime authorization during these grace periods when they were clocked-in but
    not on-shift. After clocking in, appellants’ only duty was to report to their work
    stations by the start of their shifts. Appellants were also instructed to cease
    working fifteen to thirty minutes before the end of their shifts to allow time for
    cleaning up, putting away tools, and entering time and job data on company
    computers.
    The four named appellants (Von Friewalde, Hartman, Compas and Bevins)
    filed this collective action in the Western District of Texas, claiming that Boeing
    unlawfully denied them and their fellow employees compensation for overtime
    work in violation of section 207 of the FLSA. Subject to Boeing’s right to later
    seek decertification, the parties entered into a conditional agreement certifying
    the collective action under 
    29 U.S.C. § 216
    (b), which allows one or more
    employees to bring suit on behalf of other “similarly situated” employees with
    their written consent. Pursuant to this agreement, the parties notified potential
    plaintiffs of the suit, and approximately seventy-six other current and former
    Boeing employees opted into the collective action. Appellants sought overtime
    wages for the following activities allegedly performed outside of their actual shift
    times: walking between their lockers and their work stations; obtaining and
    inventorying tools; donning and doffing ordinary protective gear such as safety
    glasses and hearing protection; and entering time and performing other work-
    3
    related tasks on Boeing’s computers.2
    Boeing filed a motion for summary judgment and a motion to decertify the
    collective action. On March 8, 2008, the district court granted Boeing’s motion
    for summary judgment, finding that appellants had failed to raise a fact issue
    as to whether Boeing had actual or constructive knowledge that appellants had
    performed uncompensated overtime work.                  As a consequence, the court
    dismissed Boeing’s motion to decertify the collective action as moot. On March
    13, 2008, appellants filed a motion for rehearing, which, because it was filed
    within ten days of the judgment, the district court treated as a F ED. R. C IV. P.
    59(e) motion to alter or amend the judgment. On June 10, 2008, the district
    court denied appellants’ motion, upholding its prior decision and additionally
    finding that the activities for which appellants sought overtime pay were non-
    compensable as a matter of law. Appellants timely filed this appeal.
    II. STANDARD OF REVIEW
    We review a grant of summary judgment de novo under the same legal
    standards applied by the district court. Harvill v. Westward Commc’ns, LLC,
    
    433 F.3d 428
    , 433–34 (5th Cir. 2005). Summary judgment is appropriate “if the
    pleadings, the discovery and disclosure materials on file, and any affidavits show
    that there is no genuine issue of material fact and that the movant is entitled to
    judgment as a matter of law.” F ED. R. C IV. P. 56(c). “Fact questions are viewed
    in the light most favorable to the nonmovant and questions of law are reviewed
    2
    Appellants’ original complaint also asserted that Boeing’s “9/80 program” violated
    the FLSA, because they were required to work over forty hours on some weeks without
    receiving overtime pay. Under the 9/80 program, employees still worked eighty hours
    every two weeks, but they were required to do so over a period of nine days rather than
    ten, working extra hours on most days and taking off every other Friday. However,
    plaintiffs later amended their complaint and abandoned this claim, purportedly in
    response to an Opinion Letter issued by the Department of Labor finding that the 9/80
    work schedule did not violate the FLSA’s overtime provisions.
    4
    de novo.” Dutcher v. Ingalls Shipbuilding, 
    53 F.3d 723
    , 725 (5th Cir. 1995). At
    least as to issues on which the nonmoving party would bear the burden of proof
    at trial, “‘i]f the record, taken as a whole, could not lead a rational trier of fact
    to find for the non-moving party, then there is no genuine issue for trial.’”
    Harvill at 433.
    III. DISCUSSION
    The FLSA mandates that “no employer shall employ any of his employees
    . . . for a workweek longer than forty hours unless such employee receives
    compensation for his employment in excess of the hours above specified at a rate
    not less than one and one-half times the regular rate at which he is employed.”
    
    29 U.S.C. § 207
    (a)(1). Moreover, the FLSA generally requires employers to pay
    employees for all hours worked. See 
    29 U.S.C. §§ 206
    , 207; Alvarez v. IBP, Inc.,
    
    339 F.3d 894
    , 902 (9th Cir. 2003), aff’d, 
    126 S.Ct. 514
     (2006). However, not all
    activities performed in the workplace are necessarily compensable under the
    FLSA. See 
    29 U.S.C. § 254
    (a). Therefore, as a threshold matter, we must first
    consider whether any of the “work” for which appellants seek overtime pay was
    compensable as a matter of law.3
    A. Compensability
    For the purposes of summary judgment, the district court assumed that
    at least some of the activities for which appellants sought overtime pay were
    3
    We will assume that the uncompensated activities in this suit constitute “work”
    under the FLSA, which the Supreme Court has broadly defined as “‘physical or mental
    exertion (whether burdensome or not) controlled or required by the employer and pursued
    necessarily and primarily for the benefit of the employer and his business.’” IBP, Inc. v.
    Alvarez, 
    126 S.Ct. 514
    , 519 (2006) (quoting Tenn. Coal, Iron & R. Co. v. Muscoda Local No.
    123, 
    64 S.Ct. 698
    , 703 (1944)). In fact, the Court has clarified that even “‘exertion’ [is] not
    in fact necessary for an activity to constitute ‘work’ under the FLSA,” for an employee may
    be hired “‘to do nothing, or to do nothing but wait for something to happen.’” 
    Id.
     (quoting
    Armour & Co. v. Wantock, 
    65 S.Ct. 165
    , 168 (1944)).
    5
    compensable. However, upon denying appellants’ motion for rehearing, the
    district court ultimately concluded that the following activities were non-
    compensable as a matter of law: “(1) obtaining tool bags; (2) donning safety
    glasses and hearing protection; (3) walking to and from lockers; (4) signing on
    to and using company computers; and (5) cleaning up their designated work
    locations at the end of their shifts.”
    In Anderson v. Mount Clemens Pottery Co., the Supreme Court held that,
    subject to a de minimis exception, certain preliminary activities such as donning
    work clothing and walking between the clock-in station and an employee’s work
    station were compensable under the FLSA.          
    66 S.Ct. 1187
    , 1195 (1946).
    Believing that the FLSA had been “interpreted judicially in disregard of long-
    established customs, practices, and contracts between employers and
    employees,” Congress responded by passing the Portal-to-Portal Act of 1947. See
    
    29 U.S.C. § 251
    . The Portal-to-Portal Act amended the FLSA to specifically
    relieve employers of the obligation to compensate employees for
    “(1) walking, riding, or traveling to and from the actual place of
    performance of the principal activity or activities which such
    employee is employed to perform, and
    (2) activities which are preliminary to or postliminary to said
    principal activity or activities,
    which occur either prior to the time on any particular workday at
    which such employee commences, or subsequent to the time on any
    particular workday at which he ceases, such principal activity or
    activities.”
    
    Id.
     § 254(a).   In Steiner v. Mitchell, the Supreme Court determined that
    preliminary or postliminary activities are compensable if they are not
    specifically excluded under section 254(a)(1) and are “an integral and
    indispensable part of the principal activities for which covered workmen are
    employed.” 
    76 S.Ct. 330
    , 335 (1956). “To be ‘integral and indispensable,’ an
    6
    activity must be necessary to the principal work performed and done for the
    benefit of the employer.” Alvarez, 
    339 F.3d at
    902–03 (citing, inter alia, Dunlop
    v. City Elec., Inc., 
    527 F.2d 394
    , 398 (5th Cir. 1976)). However, even if an
    activity might otherwise be compensable, we may disregard de minimis claims
    “‘concern[ing] only a few seconds or minutes of work beyond the scheduled
    working hours.’” Id. at 903 (quoting Anderson, 
    66 S.Ct. at 1195
    ). As the Ninth
    Circuit said in Lindow v. United States, 
    738 F.2d 1057
     (9th Cir. 1984), “[m]ost
    courts have found daily periods of approximately 10 minutes de minimus even
    though otherwise compensable.” 
    Id. at 1062
    . See also Anderson v. Pilgrim’s
    Pride Corp., 
    147 F. Supp. 2d 556
    , 564 (E.D. Tex. 2001) (same), aff’d, 44 Fed
    App’x 652 (5th Cir. 2002 (affirmed “essentially for the reasons stated by the
    careful opinion of Judge Hanna”).
    We agree with the district court that obtaining standard tool bags (located
    in easily accessible cabinets near appellants’ lockers), clocking in and out on
    AutoTime (a process that normally took seconds), and donning and doffing
    generic safety gear (e.g., hearing and eye protection) involved a de minimis
    amount of time and therefore were non-compensable activities under the FLSA.
    See id.; see also Anderson, 
    66 S.Ct. at 1195
    .            We also hold that the time
    appellants spent walking to and from their lockers at the beginning and end of
    each shift was non-compensable, as the Portal-to-Portal Act specifically provides
    that walking before and after the performance of an employee’s principal
    activities is non-compensable.4 See 
    29 U.S.C. § 254
    (a)(1). And, we also agree
    with the Second Circuit – and with the district court here – that donning and
    4
    We recognize that, under the “continuous workday” rule, “any walking time that
    occurs after the beginning of the employee’s first principal activity and before the end of
    the employee’s last principal activity . . . is covered by the FLSA.” Alvarez, 126 S.Ct. at
    525; see 
    29 U.S.C. § 254
    (a)(1). Here, however, appellants seek compensation for time spent
    walking before and after they performed their principal activities each day.
    7
    doffing of generic protection gear such as safety glasses and hearing protection,
    are in any event “non-compensable, preliminary tasks” under the Portal-to-
    Portal Act. See Gorman v. Consolidated Edison Corp., 
    488 F.3d 586
    , 594 (2d Cir.
    2007).
    However, we conclude that the following activities, if actually proven to
    involve more than a de minimis amount of time, were compensable as a matter
    of law: performing substantive tasks on Boeing computers, such as checking
    work-related emails and conducting research pertinent to job assignments;
    checking specialized tools in and out of the tool crib and, for those working as
    tool control attendants, preparing the tool crib prior to the shift and putting
    away tools at the close of the shift; and cleaning up work stations at the end of
    the shift. As these activities were necessary to appellants’ principal duties and
    were performed for Boeing’s benefit, they were “integral and indispensable” to
    appellants’ jobs. See Alvarez, 
    339 F.3d at
    902–03. Therefore, the district court
    erred to the extent that it held that these activities were not compensable as a
    matter of law.
    Our determination that some of the complained-of activities are
    compensable does not necessarily mean that appellants are entitled to recover
    under the FLSA. Appellants must still meet their burden of proving that they
    performed these activities “off the clock” and were not adequately paid for their
    efforts.
    B. Summary Judgment Evidence
    An employee seeking unpaid overtime compensation under the FLSA must
    first demonstrate that he “performed work for which he was not properly
    compensated.” Anderson, 
    66 S.Ct. at 1192
    . This may prove difficult where the
    employer has failed to keep accurate or adequate records, as appellants argue
    is the case here due to Boeing’s use of AutoTime. See 
    id.
     In such a situation,
    8
    however, “[t]he solution . . . is not to penalize the employee by denying him any
    recovery on the ground that he is unable to prove the precise extent of
    uncompensated work.” 
    Id.
     Rather, an employee is deemed to have met his
    burden
    if he proves that he has in fact performed work for which he was
    improperly compensated and if he produces sufficient evidence to
    show the amount and extent of that work as a matter of just and
    reasonable inference. The burden then shifts to the employer to
    come forward with evidence of the precise amount of work
    performed or with evidence to negative the reasonableness of the
    inference to be drawn from the employee’s evidence. If the employer
    fails to produce such evidence, the court may then award damages
    to the employee, even though the result be only approximate.
    Id.; see also Harvill, 
    433 F.3d at 441
    .
    Further, an employee must prove that he was “employed” during the time
    for which he seeks overtime compensation, which requires a showing that the
    employer had either actual or constructive knowledge that he was working
    overtime.   Newton v. City of Henderson, 
    47 F.3d 746
    , 748 (5th Cir. 1995).
    Constructive knowledge exists if by “exercising reasonable diligence” an
    employer would become aware that an employee is working overtime. Brennan
    v. Gen. Motors Acceptance Corp., 
    482 F.2d 825
    , 827 (5th Cir. 1973).          “‘An
    employer who is armed with [knowledge that an employee is working overtime]
    cannot stand idly by and allow an employee to perform overtime work without
    proper compensation, even if the employee does not make a claim for the
    overtime compensation.’”     Newton, 
    47 F.3d at 748
     (alteration in original)
    (quoting Forrester v. Roth’s I.G.A. Foodliner, Inc., 
    646 F.2d 413
    , 414 (9th Cir.
    1981)); see also 
    29 C.F.R. § 785.11
     (“Work not requested but suffered or
    permitted is work time.”). However, if the “‘employee fails to notify the employer
    or deliberately prevents the employer from acquiring knowledge of the overtime
    9
    work, the employer’s failure to pay for the overtime hours is not a violation of
    § 207.’” Newton, 
    47 F.3d at 748
     (quoting Forrester, 646 F.3d at 414); see also
    Harvill, 
    433 F.3d at 441
    .
    The district court determined that appellants had failed to raise a genuine
    issue of material fact as to whether Boeing had actual or constructive knowledge
    that appellants were working unpaid overtime; therefore, the court granted
    Boeing’s motion for summary judgment. The primary evidence presented by
    appellants in this case was the deposition testimony of three named appellants,
    two opt-in appellants, and several Boeing managers.                 None of the other
    appellants testified, nor did appellants provide any substantive answers to
    Boeing’s interrogatories.
    Appellants allege that there exists a “common nucleus of liability facts”
    among all of their claims. After reviewing the evidence, we disagree. Indeed,
    unlike the employees in Anderson and Alvarez, the details surrounding each of
    their claims vary in significant ways, such that few if any of the appellants are
    “similarly situated” for the purposes of the FLSA. See 
    29 U.S.C. § 216
    (b).
    Therefore, we address each appellant’s claim individually.                Moreover, we
    conclude that the claims of all those appellants who have not produced any
    evidence at all, including named appellant Mark Compas and all but two of the
    opt-in appellants, necessarily fail. Those appellants had numerous opportunities
    to provide deposition testimony, affidavits, documents, or answers to
    interrogatories in support of their claims.5 As it stands, we know nothing of
    those appellants other than their names and the fact that they were allegedly
    5
    Appellants had ample time to come forward with evidence in support of their
    claims, as the deadline for completing discovery was at their requests extended on multiple
    occasions. In response to Boeing’s interrogatories, appellants repeatedly stated that they
    were “in the process of attempting to determine the requested information and will
    continue to obtain and supplement this information,” yet they never did so.
    10
    employed in some unidentified capacity by Boeing when AutoTime was in use.
    Therefore, we affirm the district court’s dismissal of their claims. As to those
    appellants who submitted depositions (or other summary judgment evidence),
    we review the relevant portions of their evidence here.
    i. Deposition Testimony
    Named appellant Robert Bevins worked as a mechanic and ramp operator
    at Boeing.   Bevins stated that, generally speaking, he considered the time
    between clocking in and the start of his shift to be his own personal time.
    However, Bevins testified that occasionally when working as a ramp operator,
    he and his fellow crewmen would be instructed to start work approximately
    fifteen minutes before their shift when an aircraft arrived at the facility early.
    According to Bevins, this occurred perhaps five times over a six-year period.
    Bevins also testified that, over the course of approximately a decade, he was
    forced on two or three occasions to start work ten to fifteen minutes early to take
    care of potentially hazardous situations (e.g., an engine suspended from a cable)
    that were left by workmen on the preceding shift. Additionally, Bevins stated
    that occasionally managers would begin crew meetings five to ten minutes before
    a shift, but when crew members complained, the managers would nearly always
    wait until the start of the shift to commence. Finally, Bevins testified that he
    was forced to stay fifteen to twenty-five minutes late twice to search for a lost
    tool and approximately four times (of unestimated length) to place protective
    covers on airplane engines. Bevins did not request overtime compensation on
    any of these occasions.
    Named appellant Dave Hartman worked as a quality inspector at Boeing,
    where he was responsible for inspecting the mechanics’ work. Hartman testified
    that when he was required to stay late, he would normally send an email to his
    manager, who would approve the overtime work. Upon a couple of occasions
    11
    when he was not paid for an unestimated amount of overtime, Hartman
    complained to Boeing’s ethics department, which “blew [him] off.” Hartman also
    stated that on most days he did not work late, but when he was specifically
    asked to by his managers, he was compensated for it. Finally, Hartman said
    that, on his own initiative, he would often check his work email on company
    computers five to ten minutes before his shift without telling his superiors.
    Named appellant William Von Friewalde, who worked as a mechanic,
    claimed that he should be paid fifteen minutes of overtime per day based upon
    the average amount of time that he was clocked-in but not on-shift. However,
    it is apparent from his testimony that he was not always performing
    compensable activities during those grace periods for which he now seeks
    compensation.    While some of his post-shift time may have been spent
    performing compensable activities such as cleaning up his work station, the only
    consistent pre-shift activities that Von Friewalde complained of were obtaining
    his tool bag and his personal safety equipment before each shift, both of which
    we have concluded involve a de minimis amount of time and are non-
    compensable. When pressed for more specifics about his overtime claims, Von
    Friewalde stated that on the three or four occasions when he did inform the
    Boeing Human Relations department that he was not being paid for overtime
    work, they told him that his time was “locked” in the computer and could not be
    changed. Von Friewalde estimated that the total amount of overtime at issue
    in all these discussions was at most half an hour, which he accumulated over a
    year-long period.    Additionally, Von Friewalde stated that most of his
    supervisors would ensure that he was paid overtime if he told them he had
    worked extra hours. However, he also testified that most of the time he would
    not request overtime for the extra five to ten minutes he spent cleaning up at the
    end of a shift, because to do so involved too much effort on a regular basis and
    12
    felt like “chasing a rabbit.” Finally, Von Friewalde alleged that some of his
    managers physically erased his overtime hours, though he could not provide any
    details as to how much time was deleted or when or how often that occurred.
    Edward Montelongo, an opt-in appellant, was also a mechanic at Boeing.
    Montelongo testified that when he performed overtime work specifically at his
    manager’s request (i.e., when he was instructed to come into work early, when
    planes would arrive before the scheduled shift, or when a particular task could
    not be completed by the end of the shift), he was not always compensated. When
    he complained to his managers, they assured him that they would “take care of
    it” but never followed through. He testified that on a number of occasions his
    managers knowingly required him to work anywhere from half an hour to two
    hours of overtime for which he was never paid.6
    Jesus Lozano, an opt-in appellant who worked as a tool control attendant
    in the tool crib, presented the most satisfactory evidence of any appellant.
    Unlike any of the other appellants, Lozano kept track of his time over a three to
    four year period and submitted spreadsheets to the district court purportedly
    indicating when he performed and was paid for the overtime and when he was
    not paid for overtime performed. In order to produce a general estimate of his
    unpaid overtime, Lozano reviewed his spreadsheets covering one month and
    calculated approximately five hours of overtime for which he was never paid.
    Although Lozano was not allowed to dispense tools prior to the start of the shift,
    he testified that he consistently had to begin work ten to twenty minutes early
    to prepare the tool crib for the start of the shift, when the mechanics would come
    to obtain their tools. Therefore, Lozano attempted to arrive early enough every
    6
    Because AutoTime automatically registers overtime when an employee clocks in
    more than thirty minutes prior to a shift, we note that this apparently would have required
    his managers to manually erase Montelongo’s time.

    day to clock in at least a little more than thirty minutes before his shift, so that
    AutoTime would automatically record his overtime.            As a result, Lozano
    admitted that he received overtime pay “almost every day.” However, when he
    failed to clock in before the start of the thirty-minute grace period, Lozano
    generally did not inform his superiors (allegedly because they told him not to
    bother) and therefore lost that overtime. In addition, Lozano stated that on most
    days, he was able to close up the tool crib promptly at the end of his shift.
    However, often he had to stay several minutes late to receive and inventory tools
    when the mechanics were running behind schedule. Lozano stated that when
    he complained to his manager about not being paid overtime, his manager took
    no action other than to advise him to leave as quickly as possible at the end of
    the shift.   However, Lozano did admit that at least one of his managers
    authorized overtime freely when notified.
    For their own part, all of Boeing’s managers who were deposed testified
    that they always paid overtime when it was pre-authorized or when an employee
    informed them that he or she had worked extra time. One manager, Wallace
    Hatcher, stated that although he would approve overtime after-the-fact when
    requested, he would discourage his employees from working unauthorized
    overtime. Hatcher stated that it was not uncommon for some employees to work
    on company computers prior to the start of their shift for their own convenience,
    but he indicated that those employees could have waited until they were on the
    clock to perform those tasks. He also admitted to having on some occasions
    erased unauthorized overtime on some employees’ timecards that had registered
    automatically when they clocked out after the eighteen-minute grace period at
    the end of their shifts.
    Another manager, Jesus Morales, stated that it was sometimes impossible
    for the mechanics to stop work with enough time to clean up before the shift’s
    14
    end, because they were required to leave the workplace in a safe condition.
    Morales and another manager, Robert Ryan, testified that they would always
    authorize overtime when their employees requested it but that employees would
    often work several minutes past their shifts without asking for overtime.
    Morales believed that most employees did not consider it worthwhile to go
    through the trouble of seeking overtime authorization for just a few minutes of
    extra work.
    ii. Analysis
    We conclude that, for several reasons, appellants Bevins, Hartman, and
    Von Friewalde have failed to present sufficient evidence to permit a reasonable
    factfinder to conclude that they had met their burden under the FLSA. First of
    all, their claims rest upon an amount of unpaid overtime that is de minimis as
    a matter of law. See Anderson, 
    66 S.Ct. at 1195
     (“[I]t is appropriate to apply a
    de minimis doctrine so that insubstantial and insignificant periods of time spent
    in preliminary activities need not be included in the statutory workweek.”); see
    also Alvarez, 
    339 F.3d at 903
    . In Anderson and Alvarez, the workers produced
    evidence that they regularly engaged in the same compensable activities day
    after day yet were never paid for their efforts.     See Anderson, 
    66 S.Ct. at
    1190–91; see also Alvarez, 
    339 F.3d at
    898–99. Therefore, the accumulated
    amount of unpaid overtime was substantial, and a factfinder could reasonably
    infer the amount of damages based upon the activities in question and the
    number of days worked. Here, in contrast, neither Bevins, Hartman, nor Von
    Friewalde proved that they regularly performed compensable activities without
    being paid. Rather, on random occasions occurring perhaps a handful of times
    over the course of a year or more, they allegedly worked overtime amounting to
    some small portion of an hour without compensation. Their testimony reveals
    the de minimis nature of their claims and does not constitute “sufficient evidence
    15
    to show the amount and extent of that work as a matter of just and reasonable
    inference” under the standard laid out in Anderson. See 
    66 S.Ct. at 1192
    .
    Moreover, these appellants admitted that, on the vast majority of
    occasions, they were paid when they notified their superiors that they had
    worked overtime. Their claims largely arise from days on which they failed to
    inform their managers that they had been forced to stay a few minutes late to
    finish cleaning up, return tools, etc. While an employer may not “stand idly by”
    without paying an employee that he knows or should know is working overtime,
    an employee has a duty to notify his employer when he is working extra hours.
    See Newton, 
    47 F.3d at 748
    . Further, it is undisputed that all of Boeing’s
    employees were aware of its policy prohibiting overtime work without
    authorization, and we have expressly rejected the notion that an employer does
    “not have the right to require an employee to adhere to its procedures for
    claiming overtime.” 
    Id. at 749
    . Therefore, in the case of Hartman for instance,
    Boeing is not responsible for paying for the few moments he voluntarily spent
    checking work emails prior to his shift without notifying his manager. More
    broadly speaking, Boeing cannot be held liable for the sporadic occasions when
    its employees chose to start work early or were forced by circumstances (perhaps
    of their own making) to work a few minutes late but never informed their
    superiors.
    In the case of Von Friewalde, his claim that he worked on average fifteen
    minutes of unpaid overtime per day is, on its face, substantial enough to
    overcome the de minimis rule. However, Von Friewalde’s testimony does not
    establish that he was performing an extra fifteen minutes of compensable work
    each day, but rather only that he was clocked-in for an extra fifteen minutes. As
    the district court observed, “[t]he clock-in and clock-out times do not show what
    the employee was actually doing during those times, and they are not evidence
    16
    of actual or constructive knowledge that compensable work was being
    performed.” Von Friewalde’s testimony does not support the conclusion that he
    should be paid for all of the time he was clocked-in but not on-shift; nor does it
    contain, or furnish any basis for inferring, any reasonable estimate of the
    amount of time worked on such occasions. Further, Von Friewalde admitted
    that he normally did not notify his superiors that he was working overtime.
    And, when he did request overtime but they still refused to pay him, the amount
    of time involved was de minimis.
    In Lindow, “[a]s a general rule, the [employer] corps did not pay overtime
    for intervals of less than fifteen minutes.” 
    Id.,
     
    738 F.2d at 1063
    . In denying
    recovery for pre-shift compensable activities, the Ninth Circuit observed:
    There was also a wide variance in the amount of pre-shift time
    spent on compensable activities as opposed to social activities.
    Although plaintiffs spent an average of 7 to 8 minutes a day reading
    the log book and exchanging information, they did not always
    perform these duties before their shifts. The Corps would have had
    difficulty monitoring this pre-shift activity. Moreover, although
    plaintiffs reported early on a regular basis, they did not regularly
    engage in compensable activities. The district court found that
    ‘most employees came in about 15 minutes early, and sometimes
    spent a portion of this time reading the log book or exchanging
    information.’     Although plaintiffs’ aggregate claim may be
    substantial, we conclude that their claim is de minimus because of
    the administrative difficulty of recording the time and the
    irregularity of the additional pre-shift work.
    ...
    Occasionally, a lockage would occur at the time of a shift change and
    early arriving employees would be sent to the locks to relieve the
    operator. This practice enabled the departing employee to avoid
    having to work past the scheduled shift.
    The district court found that an employee was asked to relieve
    17
    the previous operator only once or twice a month, and that it took 5
    to 15 minutes to relieve an operator. It properly concluded that this
    claim was de minimus. The aggregate amount of time involved was
    insignificant and the practice was irregular.
    
    Id. at 1063-64
    . Much of the foregoing is analogous to most of the claims here and
    properly supports their denial.
    On the other hand, we conclude that Montelongo has created a fact issue
    as to whether Boeing violated the FLSA in failing to pay him overtime. Unlike
    the other appellants discussed above, Montelongo claims to have worked a
    substantial amount of overtime without pay, up to two hours on some days,
    which rises above the de minimis threshold. Additionally, he performed this
    work at his managers’ request, and he notified them directly when he was never
    paid for his efforts. Therefore, because his managers were clearly aware that
    Montelongo was working overtime, Boeing’s policy against unauthorized
    overtime offers no defense.
    We also conclude that Lozano has presented sufficient evidence to create
    a fact issue as to whether he performed uncompensated overtime work of which
    his superiors knew or should have known. Lozano testified that he consistently
    performed overtime work for which he was not compensated, and he was the
    only appellant to submit any sort of documentary evidence in support of his
    claim. Unlike the other appellants in this collective action, for whom unpaid
    overtime was a seemingly random and rare event, Lozano was forced to start
    work early and to finish late on a daily basis. Apparently, the Boeing policy
    against working during the pre- and post-shift grace periods did not apply to tool
    control attendants, who were expected to use that time to prepare the tool crib
    before the shift and to put away everyone’s tools at the end of the shift. It is also
    clear from Lozano’s testimony that his superiors knew or should have known
    that he was working extra hours on the days for which he did not receive
    18
    overtime.
    Thus, for summary judgment purposes, we hold that opt-in appellants
    Montelongo and Lozano have adequately demonstrated that they performed a
    more substantial than de minimus amount of uncompensated overtime work and
    have produced “sufficient evidence to show the amount and extent of that work
    as a matter of just and reasonable inference.” See Anderson, 
    66 S.Ct. at 1192
    .
    Therefore, the district court erred in dismissing their claims at this stage of the
    proceedings. However, we conclude that all of the other appellants have failed
    to present any evidence sufficient to support a judgment for recovery in their
    favor under the FLSA and that hence summary judgment was properly granted
    dismissing their claims. Most appellants, including Compas and almost all of
    the opt-ins, failed to present any evidence at all. As to named appellants Bevins,
    Hartman, and Von Friewalde, their claims fail for a number of reasons: either
    they worked a de minimis amount of overtime, they failed to notify their
    superiors, or they performed overtime work on their own initiative in
    contravention of Boeing’s overtime policy.
    IV. CONCLUSION
    We hold that appellants Montelongo and Lozano have presented sufficient
    evidence to create a fact issue. Therefore, we VACATE and REMAND as to their
    claims. However, as we find that all of the other appellants in this collective
    action have failed to present any sufficient evidence to justify recovery and that
    summary judgment was properly granted against them, we AFFIRM the district
    court’s dismissal of their claims.
