    ARGUED SEPTEMBER 13, 2021 — DECIDED DECEMBER 14, 2021

    Before RIPPLE, ROVNER, and SCUDDER, Circuit Judges.
    RIPPLE, Circuit Judge. Michael Moss brought this class ac-
    tion against United Airlines (“United”) under the Uniformed
    Services Employment and Reemployment Rights Act
    (“USERRA”). This statute requires employers to provide
    employees on military leave any seniority-based benefit the
    employee would have accrued but for the military leave.
    USERRA also requires employers to provide employees on
    2                                                           No. 20-3246
    military leave any nonseniority-based benefits that the em-
    ployer provides to employees on a comparable leave of ab-
    sence. This latter provision is not at issue in this appeal.
    The district court granted summary judgment to United
    Airlines on Mr. Moss’s claim that the company had violated
    USERRA by denying sick-time accrual in excess of ninety
    days to military reservist employees. The district court held
    that sick-time accrual was not a seniority-based benefit with-
    1
    in the meaning of the statute.
    We now affirm the judgment of the district court. The
    district court correctly determined that United’s sick-time
    accrual is not a seniority-based benefit. For a benefit to be
    seniority-based, the benefit must be a reward for length of
    service. Sick leave is not such a reward.
    I
    BACKGROUND
    A.
    From April 1, 2005, to 2010, United Air Lines pilots, who
    also served in the reserve components of the Armed Forces
    of the United States and were called periodically to active
    duty, accrued sick time throughout their entire military
    leave. In contrast, Continental Pilots, who served the Coun-
    try in the same capacity, accrued sick time only through the
    first thirty days of their military leave during the same peri-
    od.
    1 The court further held that military leave was not comparable to other
    forms of leave offered by United. This part of the district court’s holding
    is not at issue on this appeal.
    No. 20-3246                                                                3
    In 2010, these two airlines began a merger process. They
    first became wholly owned subsidiaries of United Continen-
    tal Holdings. During this stage, the separate bargaining
    agreements of each legacy airline continued to govern for
    two years. In March 2013, United and Continental merged
    2
    into a single entity—United Airlines. Nevertheless, the poli-
    cies of the two legacy airlines continued in effect until Unit-
    ed Airlines standardized the sick-time policy in 2014: “[A]ll
    pilots only accrued sick time during the first ninety (90) days
    3
    of military leave.”
    The operative collective bargaining agreement sets forth
    United Airlines’ post-standardization policy: “[F]or each Bid
    Period of Active Employment, five (5) hours of sick leave
    shall be deposited into a Pilot’s sick leave bank up to a max-
    4
    imum of 1300 hours.” “Active Employment” is when “a Pi-
    lot is available for assignment, on sick leave or on vacation
    5
    for any part of a Bid Period.” A Bid Period is, essentially,
    one month. Therefore, all pilots accrue a consistent five
    hours of sick time per Bid Period. Two final provisions on
    United’s sick-time policy are also relevant: (a) “Sick leave
    with pay shall be granted only in cases of actual sickness[,]”
    2Before the merger, “United Air Lines” had a space; following the mer-
    ger, the space was removed: “United Airlines.”
    3 R.95-1 at 4. We will refer to pilots or leave policies from before 2014 as,
    for example, the “legacy United pilots” or “legacy Continental leave.”
    Anything after 2014 will be the “modern” or “current” era.

    and (b) “upon separation of employment, a Pilot shall not
    6
    receive payment for any balance in his sick leave bank.”
    United Air Lines hired Michael Moss, the plaintiff, in ear-
    ly 2000. On September 16, 2009, United Air Lines placed
    Mr. Moss on furlough, but he was hired by Continental on
    January 24, 2012. He continued working at United Airlines
    through the merger process. Throughout the relevant time
    period, he also held a commission as a Lieutenant Colonel in
    the Reserve Component of the United States Marine Corps.
    B.
    On August 30, 2016, Mr. Moss brought this action against
    United Airlines, alleging violations of USERRA. Count I (the
    only Count at issue on appeal) alleged that United violated
    USERRA by denying sick-time accrual to pilots on military
    leave because (a) sick time is a seniority-based benefit and
    thus should have continuously accrued; or (b) sick-time ac-
    crual was available to pilots on comparable periods of leave.
    Count II made the same allegations about vacation time ac-
    crual; Count III addressed the same alleged violations with
    respect to pension payments.
    The district court certified classes for each Count. The
    sick-time class for Count I is comprised of:
    All past and present pilots employed by the
    Company from April 1, 2005, to the present,
    who: (i) did not accrue sick time while on peri-
    ods of military leave from April 1, 2005, to the
    present; and (ii) were not at the maximum sick
    6 Id.   § 13-A-5; Id. § 13-B.
    No. 20-3246                                                                  5
    leave accrual level of 1,300 hours at the time of
    their military leave(s) of absence or at any time
    7
    thereafter.
    The parties moved for summary judgment. United asked
    for summary judgment on all counts; Mr. Moss only asked
    for summary judgment on Counts I and II.
    The district court granted United’s motion as to Counts I
    and II. The district court first addressed Count II (vacation
    accrual) and held that “the ‘real nature’ of vacation days in
    this case is not a reward for length of service. Thus, vacation
    days are not a seniority-based benefit under the collective
    7  R.68 at 7. When the class definition sweeps within it individuals who
    could not have suffered injury, it is too broad. See Kohen v. Pac. Inv.
    Mgmt. Co., 
    571 F.3d 672
    , 677 (7th Cir. 2009). In TransUnion LLC v. Ramirez,
    
    141 S. Ct. 2190
    , 2205 (2021), the Supreme Court reminded us that “Article
    III grants federal courts the power to redress harms that defendants
    cause plaintiffs, not a freewheeling power to hold defendants accounta-
    ble for legal infractions.” 
    Id. at 2205
     (quoting Casillas v. Madison Ave. As-
    socs., Inc., 
    926 F.3d 329
    , 332 (7th Cir. 2019)). It also made clear that plain-
    tiffs must “maintain their personal interest in the dispute at all stages of
    litigation.” 
    Id. at 2208
    . Article III standing, the irreducible constitutional
    minimum, requires a plaintiff to have suffered an injury in fact. Lujan v.
    Defs. of Wildlife, 
    504 U.S. 555
    , 560 (1992).
    Although it did not have the benefit of TransUnion when it focused
    on the class definition issue, the district court nevertheless examined the
    necessity of injury in fact. On this record, we are not prepared to say that
    the district court erred. Nevertheless, we note that the advent of
    TransUnion sets the stage for a renewed examination of the intersection
    of the demands of Article III and the requirements of Rule 23 of the Fed-
    eral Rules of Civil Procedure.
    6                                                             No. 20-3246

    bargaining agreement.” In reaching this conclusion, the dis-
    trict court rejected Mr. Moss’s argument that vacation-time
    accrual is a seniority-based benefit because it “accrues solely
    9
    with the passage of time.” Noting that “this is true of any
    employment benefit,” the court concluded that this charac-
    teristic “is not particularly informative, let alone dispositive,
    10
    of whether vacation day accrual is seniority-based.”
    The court then concluded that “[s]ince vacation days are
    not a seniority-based benefit, Plaintiffs are entitled to only
    the ‘other’ benefits ‘generally provided,’ to employees on
    11
    ‘comparable leaves of absence.’” The district court disa-
    greed with Mr. Moss that United’s jury duty, association
    leave, and sick leave are “‘comparable’ to military leave,
    such that vacation time accrual should be available to mili-
    12
    tary leave longer than 90 days.”
    8 R.106 at 8; cf. Ala. Power Co. v. Davis, 
    431 U.S. 581
    , 589 (1977) (“If the
    benefit … is in the nature of a reward for length of service, it is a ‘perqui-
    site of seniority.’”); Accardi v. Penn. R.R. Co., 
    383 U.S. 225
    , 230 (1966)
    (“The use of the label ‘compensated service’ cannot obscure the fact that
    the real nature of these payments was compensation for loss of jobs.”).

    , 865 (7th Cir. 2009)).

    Id.
     at 10–13. Mr. Moss has dropped this argument from his appeal.
    Instead, he argues that United’s legacy military leave policy should be
    compared to Continental’s legacy military leave policy.
    No. 20-3246                                                                 7
    Having disposed of Count II (vacation accrual), the dis-
    trict court turned to Count I, the sick-time accrual claim, and
    entered summary judgment for United. It stated:
    Likely because there is no material difference
    in the accrual of “sick time” and “vacation
    time” under the collective bargaining agree-
    ment, Plaintiffs’ arguments on Count I mirror
    their arguments on Count II. Therefore, the
    Court grants summary judgment to Defend-
    ants on Count I for the same reasons it grants
    summary judgment to Defendants on
    13
    Count II.
    The district court then addressed potential objections
    based upon the collective bargaining agreement’s different
    policies on the accrual of sick time and the accrual of vaca-
    tion time. The court explained that “the numbers of hours or
    days accrued, and the rates of accrual” are “differences in
    the ‘particular formulas’ by which accrual is ‘calculated,’ and
    14
    thus are not material to the Court’s analysis.”
    The parties subsequently settled Count III, and the dis-
    trict court approved that settlement on October 19, 2020. Af-
    ter the approval of the settlement, the district court entered
    13 
    Id.
     at 13–14 (footnote omitted). Mr. Moss contends that the district
    court’s treatment of Count I violated Circuit Rule 50 for not adequately
    documenting the reasons for the grant of summary judgment. We disa-
    gree. The district court’s rationale was clear from the record and the
    court’s opinion. See Stoller v. Pure Fishing Inc., 
    528 F.3d 478
    , 480 (7th Cir.
    2008).

    final judgment, and Mr. Moss timely appealed the grant of
    summary judgment on Count I, the sick-time accrual claim.

    DISCUSSION
    “We review the district court’s grant of summary judg-
    ment de novo.” Flexible Steel Lacing Co. v. Conveyor Accesso-
    ries, Inc., 
    955 F.3d 632
    , 643 (7th Cir. 2020). “Summary judg-
    ment is appropriate when ‘there is no genuine dispute as to
    any material fact and the movant is entitled to judgment as a
    matter of law.’” 
    Id.
     (quoting Fed. R. Civ. P. 56(a)). Here the
    facts are not disputed.
    We also note that it is well established that any “interpre-
    tative doubt is to be resolved in the veteran’s favor,” Brown
    v. Gardner, 
    513 U.S. 115
    , 118 (1994), and that “provisions for
    benefits to members of the Armed Services are to be con-
    strued in the beneficiaries’ favor,” King v. St. Vincent’s Hosp.,
    
    502 U.S. 215
    , 220 n.9 (1991).
    A.
    USERRA is the modern iteration of a line of statutes de-
    signed to protect employment and reemployment rights of
    those who serve in the Armed Forces. First, the Selective
    Training and Service Act of 1940 required private employers
    to reemploy qualified military veterans to their previous po-
    sition or “to a position of like seniority, status, and pay.”
    Pub. L. No. 76-783, § 8(b)(3)(C), 
    54 Stat. 885
    , 890 (codified at
    
    50 U.S.C. § 301
     et seq. (repealed 1955)). In an early case inter-
    preting the Selective Training and Service Act, the Supreme
    Court gave breath to what has become known as the “escala-
    tor principle”: “[The returning servicemember] does not step
    back on the seniority escalator at the point he stepped off.
    No. 20-3246                                                     9
    He steps back on at the precise point he would have occu-
    pied had he kept his position continuously during the war.”
    Fishgold v. Sullivan Drydock & Repair Corp., 
    328 U.S. 275
    , 284–
    85 (1946). This principle was codified in the Veterans’
    15
    Reemployment Rights Act and continues to be a founda-
    tional principle of seniority-based reemployment rights un-
    der USERRA.
    Enacted in 1994, USERRA serves three purposes:
    (1) to encourage noncareer service in the uni-
    formed services by eliminating or minimizing
    the disadvantages to civilian careers and em-
    ployment which can result from such service;
    (2) to minimize the disruption to the lives of
    persons performing service in the uniformed
    services as well as to their employers, their fel-
    low employees, and their communities, by
    providing for the prompt reemployment of
    such persons upon their completion of such
    service; and
    (3) to prohibit discrimination against persons
    because of their service in the uniformed ser-
    vices.
    
    38 U.S.C. § 4301
    . USERRA was not intended to change or
    disrupt the longstanding caselaw developed under the pre-
    decessor statutes. Congress viewed the existing law protect-

    ing veterans’ rights and the cases interpreting those laws as
    “successful,” and intended them to remain in full effect, to
    the extent consistent with USERRA. 
    20 C.F.R. § 1002.2
    .
    B.
    1.
    Mr. Moss first submits that he is entitled to sick-pay cred-
    it during his time of military service because sick pay is a
    seniority benefit of his employment with United. He views
    sick time as a future-oriented benefit because it provides
    economic security in case of illness. In support of this charac-
    terization, Mr. Moss notes that sick-time accrual does not
    expire annually, can only be used if an employee is sick, and
    is not paid out at the end of an employee’s employment. The
    work requirement is, in his view, illusory because the benefit
    accrues without the performance of actual work; working
    additional hours cannot increase the sick time accrued.
    These considerations, considered together, demonstrate, in
    his view, that United’s sick-time accrual is a perquisite of
    seniority and therefore should have accrued while Mr. Moss
    was on military leave.
    United disagrees. In its view, sick-time accrual is not a
    seniority-based benefit for two main reasons. First, all em-
    ployees earn the same amount of sick time. There is no vest-
    ing threshold; employees start to accrue sick time on their
    first day of work. Second, employees can only use sick time
    when they are actually sick. Employees cannot bank time
    over years knowing that the time can be used for a longer
    vacation later, thus incentivizing them to keep working.
    In assessing these views, we begin, as we always do, with
    the words of the statutory provision:
    No. 20-3246                                                             11
    A person who is reemployed under this chap-
    ter is entitled to the seniority and other rights
    and benefits determined by seniority that the
    person had on the date of the commencement
    of service in the uniformed services plus the
    additional seniority and rights and benefits
    that such person would have attained if the
    person had remained continuously employed.
    
    38 U.S.C. § 4316
    (a). Thus, returning servicemembers step
    back onto the seniority escalator where they would have
    been but for the military service; they receive any seniori-
    ty-based benefits to which they would have been entitled
    had they remained continuously employed.
    A right and benefit is seniority-based if the right (1)
    “would have accrued, with reasonable certainty, had the
    veteran been continuously employed by the private employ-
    er”; and (2) if “it is in the nature of a reward for length of
    16
    service.” Ala. Power Co. v. Davis, 
    431 U.S. 581
    , 589 (1977);
    DeLee v. City of Plymouth, 
    773 F.3d 172
    , 177–78, 180 (7th Cir.
    2014) (applying the Alabama Power test); see also 
    20 C.F.R. § 1002.212
     (listing the factors set forth in the Alabama Power
    17
    test, along with one factor not relevant here, as interpretive
    guidance to determine if a benefit is seniority-based).
    16Although Alabama Power pre-dates USERRA, the Alabama Power test
    and pre-USERRA case law remain in full effect to the extent consistent
    with USERRA. See, e.g., Crews, 
    567 F.3d at
    865 (citing 
    20 C.F.R. § 1002.2
    ).
    17Whether United had an “actual custom or practice to provide or with-
    hold the right or benefit as a reward for length of service” only applies
    where the actual practice differs from the practice on paper. 20 C.F.R.
    (continued … )
    12                                                             No. 20-3246
    The Supreme Court of the United States, like the district
    court in this case, has pointed out that although the princi-
    ples set forth in Alabama Power are straightforward, their ap-
    plication in a practical setting is not always easy. See Coffy v.
    Republic Steel Corp., 
    447 U.S. 191
    , 203 (1980) (“[E]ven the
    most traditional kinds of seniority privileges could be as eas-
    ily tied to a work requirement as to the more usual criterion
    of time as an employee.” (quoting Ala. Power, 
    431 U.S. at 592
    )). As the district court noted, the difficulty is rooted in
    the practical reality that there is an “inherent tie between
    time and work” and a lack of an “objective difference be-
    tween a ‘work requirement’ (or ‘compensation for services
    rendered’) and ‘time as an employee’ (or ‘length of service’),
    18
    because employees spend their time working.”
    The Supreme Court wrestled with this conceptual prob-
    lem in Foster v. Dravo Corp., 
    420 U.S. 92
     (1975). There, Foster
    worked for his employer at the beginning of 1967, left for
    military service, and was reemployed for the remainder of
    1968. 
    Id.
     at 94–95. Although he did not meet the required
    twenty-five weeks of work for vacation benefits, he asked
    his employer for the vacation time accrued during both
    years. 
    Id. at 95
    . The Supreme Court did not sustain his claim;
    ( … continued)
    § 1002.212(c); see also id. (“Provisions of an employment contract or poli-
    cies in the employee handbook are not controlling if the employer’s ac-
    tual custom or practice is different from what is written in the contract or
    handbook.”). Here there is no allegation that United’s actual practice of
    providing sick time differed from that written in the collective bargain-
    ing agreement.
    18   R.106 at 4 (emphasis omitted).
    No. 20-3246                                                   13
    it decided that the vacation benefits at issue were properly
    characterized as “short-term compensation for work per-
    formed.” Id. at 100. In reaching that decision, the Supreme
    Court considered the work requirement, the option to earn
    more vacation time through overtime, and the pro rata pay-
    out if an employee left his employment early. In the final
    analysis, however, the nature of the benefit, the “common
    conception of a vacation as a reward for and respite from a
    lengthy period of labor” convinced the Court that the statu-
    tory provision protecting seniority rights did not apply. Id. at
    101. Foster did not hold that all vacation-time accrual was a
    nonseniority benefit. The Court explicitly noted that “the
    statute should be applied only where it clearly appears that
    vacations were intended to accrue automatically as a func-
    tion of continued association with the company.” Id.
    In Alabama Power, by contrast, the Court reasoned that
    the pension plans at issue were seniority based because their
    “true nature” was a reward for length of service.

    is the lengthy period required for pension rights to vest in

     In Coffy, the Court considered the case of
    an individual who had been laid off after his return from a
    period of military service. He received supplemental unem-
    ployment benefits for twenty-five weeks. Coffy, 
    447 U.S. at 193
    . Had his civilian work history not been interrupted by a
    period of military service, he would have received fifty-two
    weeks of supplemental unemployment benefits. 
    Id.
     at 193–
    94. The Supreme Court held the unemployment benefits
    were seniority based: Their essential function “is to provide
    economic security for regular employees in the event they
    are laid off. Protection against layoff is, of course, one of the
    traditional attributes of seniority.” 
    Id. at 200

    the employees in Coffy were only entitled to the benefits if
    they had worked two continuous years prior to being termi-
    nated. 
    Id.
     at 198–99. Thus, the benefits were a “reward for
    length of service.”

    Two of our fellow circuits already have addressed the
    question we face today. Although each court understanda-
    bly focused on the facts of the case before it, the reasoning of
    each court is helpful. In LiPani v. Bohack Corp., 
    546 F.2d 487
    ,
    490 (2d Cir. 1976), our colleagues in the Second Circuit char-
    acterized sick leave as a form of deferred compensation of
    the same general nature as vacation pay. The sick time at is-
    sue there was predicated upon a work requirement: “one
    week of paid vacation accrues after ‘six months of continu-
    ous working service.’” 
    Id.
     Also, there was no relationship
    between seniority and the benefits; all employees earned the
    same amount of sick time during each year of employment.
    
    Id.
     at 490–91. The Tenth Circuit came to the same conclusion,
    holding sick-time accrual to be nonseniority-based because it
    was tied to a work requirement. Jackson v. Beech Aircraft
    Corp., 
    517 F.2d 1322
    , 1326 (10th Cir. 1975), overruled on other
    grounds by Ala. Power, 
    431 U.S. 581
    ; see also Hoefert v. Am. Air-
    lines, Inc., 
    438 F. Supp. 3d 724
    , 735–36 (N.D. Tex. 2020) (hold-
    ing sick-time accrual to not be a seniority-based benefit
    where tied to a “month of service”).
    2.
    We now assess United’s sick-time accrual policy under
    the decisional matrix provided by Alabama Power. We first
    ask whether the right “would have accrued, with reasonable
    certainty, had the veteran been continuously employed by
    the private employer.” This factor—synthesized in Alabama
    Power from the existing caselaw—asks whether the benefit
    No. 20-3246                                                  15
    was awarded automatically or subject to discretion. See
    McKinney v. Mo.-Kan.-Tex. R.R. Co., 
    357 U.S. 265
    , 272 (1958)
    (holding that a discretionary promotion was not a perquisite
    of seniority); see also Ala. Power, 
    431 U.S. at
    585 (citing
    McKinney in explaining the development of the two-prong
    test); Coffy, 
    447 U.S. at 199
    .
    We answer this question in the affirmative. Mr. Moss
    would have continued to accrue sick time with reasonable
    certainty if he had been employed continuously by United.
    Notably, there is no discretion involved. Had Mr. Moss not
    been on military leave, it was reasonably certain that he
    would have accrued sick time.
    Having determined that the first prong of the two-part
    conjunctive test is satisfied, we turn to the second prong:
    Whether the benefit is a reward for length of service. Here,
    we think it clear that the sick pay in question is not such a
    reward. A benefit is seniority-based if the “real nature” of
    the benefit is a “reward for length of service” rather than
    “compensation for services rendered.” Ala. Power, 
    431 U.S. at
    588–89. Our inquiry is therefore whether the benefit is
    backward-looking compensation for work performed or a
    future-oriented longevity incentive.
    Alabama Power instructs that the “most significant factor
    pointing to th[e] conclusion [that the pension payment is a
    reward for length of service] is the lengthy period required
    for pension rights to vest in the employee.” 
    Id. at 593
     (em-
    phasis added). United’s sick-time accrual policy has no vest-
    ing period. From their first day at United, all pilots earn five
    16                                                        No. 20-3246
    19
    hours per Bid Period. A lack of a vesting threshold sug-
    gests sick-time accrual is not tied to seniority but is deferred
    compensation designed to cover those periods when an em-
    ployee is unable to report for work because of illness, an
    event inherent in the human condition.
    Nor do United employees accrue more sick time the
    longer they have been at the company. Here, all employees
    earn the same five hours per Bid Period, day in and day out,
    without regard to how long they have been employed. This
    consideration also suggests sick time to not be a product of
    seniority. See LiPani, 
    546 F.2d at 490
     (finding persuasive the
    lack of relationship between seniority and sick-time accrual).
    The fact that sick time is not seniority-based becomes
    clearer by comparing its real nature to that of other bene-
    20
    fits. Pensions, severance pay, and supplemental unem-
    ployment benefits incentivize workers to continue working
    19Also, we note that United provides for accelerated accrual for a pilot
    who uses more than 255 hours of sick leave because of a single illness
    and for “fronted” hours for new-hire pilots. R.94-2 § 12-A-1-a to -b.
    Mr. Moss does not suggest these facts are relevant, nor do they influence
    our analysis.
    20During the enactment of USERRA, the Director of the Office of Veter-
    ans’ Employment, Reemployment, and Training testified before Con-
    gress that: “Various courts have also found that the returning service-
    member is not entitled to benefits such as … sick days … which have
    been determined to be short term compensation for work performed.”

    Reemployment & Training, to Hon. John D. Rockefeller, Chairman,
    Comm. on Veterans’ Affs., reprinted in S. Rep. 103-158, at 93 (1993).
    No. 20-3246                                                            17

    at a company. These benefits look to the future—they give
    a reason to stay at a job and have accordingly been properly
    held to be perquisites of seniority. On the other hand, sick
    time is a respite. Without sick time, the employee would
    have had to go to work ill; with sick time, the employee has
    a respite, a break from their work, as compensation for the
    services they have rendered.
    Mr. Moss counters that attributes of United’s sick leave
    point to characterizing it as seniority-based. Specifically, he
    notes that United sick-time accrual does not expire annually,
    can only be used if an employee is sick, and is not paid out
    at the end of an employee’s employment. We think that
    these considerations, whether considered separately or to-
    gether, reaffirm that sick time is more properly characterized
    as a period designed to allow the working employee a res-
    pite and to encourage the sick employee to stay away from
    the workplace. As Mr. Moss points out, sick time does not
    expire annually. This feature might suggest an incentive to
    remain at a company (so the employee does not lose their
    banked time), but that consideration is certainly reduced in
    importance because employees cannot take sick time with-
    out actually being sick. Sick time therefore cannot be used to
    augment an employment transition, or to extend a vacation.
    Moreover, in the ordinary course of human events, sick time
    21 Ala. Power, 
    431 U.S. at
    593–94 (pension payments); Accardi, 
    383 U.S. at 230
     (severance pay); Coffy v. Republic Steel Corp., 
    447 U.S. 191
    , 205–06
    (1980) (supplemental unemployment benefits).

    will be used periodically. It is generally not regarded as pro-
    22
    tection against long-term illness or disability.
    By contrast, supplemental unemployment benefits, like
    those at issue in Coffy, provide economic security based on
    seniority. Supplemental unemployment benefits promise in-
    come where otherwise the employee would not have re-
    ceived any. In this way, supplemental unemployment bene-
    fits encourage employees to stay with an employer based on
    the promise of the future benefit. Sick time however offers a
    brief respite earned on a pro rata monthly basis, in compen-
    sation for labor, to recover and then come back to work. Sick
    time does not provide economic security in the same way
    that supplemental unemployment benefits do. It only offers
    a brief respite.
    United’s sick-time accrual policy contains, moreover, a
    work requirement. Benefits conditioned on a bona fide work
    requirement are more likely to be compensation than a re-
    ward for long service. “Generally, the presence of a work re-
    quirement is strong evidence that the benefit in question was
    intended as a form of compensation.” Foster, 
    420 U.S. at 99
    .
    Courts read through illusory and insubstantial work re-
    quirements—the labels do not control. Compare Accardi v.
    Penn. R.R. Co., 
    383 U.S. 225
    , 229–30 (1966) (explaining that
    the “use of the label ‘compensated service’ cannot obscure”
    the illusory nature of the work requirement), with Foster,
    
    420 U.S. at 99
     (explaining that providing additional benefits
    22 United also offers Medical Leave, Company Offered Leaves of Ab-
    sence, Family & Medical Leave, and Maternity/Paternity Leave. See
    R.94-2 §§ 12-B, -C, -E, -F.
    No. 20-3246                                                 19
    for overtime and pro rata payment for early termination
    suggested that the work requirement was bona fide).
    Here, the parties dispute whether the United sick leave
    policy contains a legitimate work requirement. We believe
    that it does. The collective bargaining agreement contains
    the following provision: “for each Bid Period of Active Em-
    ployment, five (5) hours of sick leave shall be deposited into
    23
    a Pilot’s sick leave bank up to a maximum of 1300 hours.”
    “Active Employment” is defined as “a Pilot is available for
    assignment, on sick leave or on vacation for any part of a Bid
    24
    Period.” A Bid Period is defined as “the period from the
    first day of, to and including the last day of each of twelve
    25
    (12) thirty (30) or thirty-one (31) day periods.”
    Mr. Moss questions whether the requirement that a pilot
    need only be available for assignment, on sick leave, or on
    vacation, is sufficiently substantial to constitute a bona fide
    work requirement. He submits that being “available for as-
    signment” “for any part of a Bid Period” could be seen as
    being no real requirement at all. United takes another view.
    It sees the work requirement in the collective bargaining
    agreement as a real effort to compensate pilots for work ac-
    tually performed. It points out that the requirement ex-
    cludes, among other things, personal leave, and thus re-
    quires the pilot to actually be working before earning sick
    time.

    24 Id.   § 2-A.
    25   Id. § 2-I.

    United has the better of the argument. By conditioning
    sick-time accrual on “Active Employment,” United condi-
    tions accrual on work. Given the nature of a pilot’s schedul-
    ing and the industry overall, counting “on call” time as
    compensated time for purposes of the sick-time program is
    reasonable.
    In sum, sick time would have accrued with reasonable
    certainty had Mr. Moss remained at United. There was no
    discretion involved. There is no vesting period and no rela-
    tionship between seniority and benefits. All United employ-
    ees accrue the same five hours per Bid Period, from the new
    hire to the most senior pilot. The real nature of sick-time ac-
    crual is to provide a respite from work, not to incentivize
    longevity.
    C.
    USERRA also prohibits providing nonseniority-based
    benefits to some employees on leave but not to employees
    26
    on comparable military leave. 
    38 U.S.C. § 4316
    (b)(1)(B).
    26 This   subsection of the statute provides:
    (b)(1) … [A] person who is absent from a position of
    employment by reason of service in the uniformed ser-
    vices shall be—
    …
    (B) entitled to such other rights and benefits not deter-
    mined by seniority as are generally provided by the em-
    ployer of the person to employees having similar senior-
    ity, status, and pay who are on furlough or leave of ab-
    sence under a contract, agreement, policy, practice, or
    plan in effect at the commencement of such service or es-
    tablished while such person performs such service.

    USERRA therefore mandates that if an employer offers non-
    seniority-based benefits to an employee taking leave, it must
    provide to servicemembers on military leave the “most fa-
    vorable” benefit offered to employees taking a comparable
    leave. 
    20 C.F.R. § 1002.150
    (b).
    In the district court, Mr. Moss argued that jury duty, as-
    sociation leave, and sick leave were comparable to military
    leave such that servicemembers were to be afforded the most
    favorable benefits that employees on those nonmilitary
    leaves received. The district court held that jury duty, asso-
    ciation leave, and sick leave were not comparable to military
    leave. Mr. Moss does not renew that argument here, and we
    therefore cannot consider it.
    Now, Mr. Moss puts forth a new argument. He asks us to
    compare legacy military United leave and legacy military
    Continental leave. We cannot. Arguments not adequately
    presented to the district court are waived on appeal. Fednav
    Int’l Ltd. v. Cont’l Ins. Co., 
    624 F.3d 834
    , 841 (7th Cir. 2010).
    Because Mr. Moss did not adequately present this issue to
    the district court, it is waived.

    38 U.S.C. § 4316
    (b).
    Because we hold that Mr. Moss waived this argument, we take no
    position on whether 
    38 U.S.C. § 4316
    (b)(1)(B) only prohibits providing a
    benefit to an employee on civilian leave but not to an employee on com-
    parable military leave or if it also prohibits providing a benefit to one
    employee on military leave but not to another on a comparable military
    leave.

    Conclusion
    We hold that sick-time accrual is not a seniority-based
    benefit. Accordingly, we affirm the decision of the district
    court.
