    Opinion for the Court filed by Circuit Judge WILKINS.
    WILKINS, Circuit Judge: Wendt Corporation (“Wendt”)
    petitions for review of a decision and order of the National
    Labor Relations Board (“NLRB” or “Board”), finding that
    Wendt engaged in unfair labor practices in violation of the
    National Labor Relations Act (“NLRA” or “Act”). For the
    reasons discussed below, we grant in part and deny in part the
    petition for review. Likewise, we grant in part and deny in part
    the cross-application for enforcement.
    I.
    Wendt is a company that designs and manufactures
    equipment for the scrap-metal recycling industry. Shopmen’s
    Local Union No. 576 (the “Union”) is the exclusive collective-
    bargaining representative of 33 employees who work in the
    warehouse and production shop of Wendt’s New York-based
    manufacturing facility. The Union filed several charges with
    the National Labor Relations Board, alleging that Wendt
    committed unfair labor practices in violation of the NLRA,
    citing various incidents and company actions affecting unit
    employees. Between September 10-14, 2018, and November
    5-7, 2018, an Administrative Law Judge (“ALJ”) held a
    hearing on the Union’s charges. The ALJ found that Wendt
    engaged in numerous unfair labor practices in violation of
    Sections 8(a)(1), (3), and (5) of the NLRA. The Board rejected
    Wendt’s exceptions and almost entirely adopted the ALJ’s
    findings, save for two determinations that are not implicated by
    the petition. Wendt seeks review of the Board’s determination
    that it engaged in unfair labor practices in violation of Sections
    8(a)(1), 8(a)(3), and 8(a)(5) of the NLRA, 
    29 U.S.C. §§ 158
    (a)(1), (3), (5). The Board submitted a cross-application for
    3
    enforcement. Central to this dispute are five incidents and
    actions Wendt took that affected unit employees.
    First, in October 2017, John Fricano, a unit employee,
    loaded an item onto a forklift and moved the forklift into a paint
    booth to paint it. As Fricano began to paint the item, Wendt
    operations director Richard Howe approached him and asked
    him whether he felt that painting with the forklift inside the
    booth was safe. Howe testified that Fricano’s eyes “doubled in
    size” and Fricano agreed that it was not safe. Joint Appendix
    (“J.A.”) 83. Two days later, Wendt plant manager Daniel
    Voigt summoned Fricano to the main office to question him
    about the forklift incident. Fricano requested the presence of a
    union representative during questioning, but Voigt denied the
    request and represented to Fricano that it would not be
    necessary because he only had to answer some questions.
    When Fricano arrived in the office, Wendt’s human resources
    official, Denise Williams, gave him a disciplinary document
    that reflected Wendt’s description of the forklift incident. The
    document included a section for Fricano to indicate agreement
    or disagreement with Wendt’s statement on the incident by
    checking a box, and it had a space for him to leave comments.
    Fricano refused to sign the document or leave a comment, but
    he checked the box indicating disagreement. Wendt then
    suspended Fricano for three days without pay. Based on this
    incident, the Board ruled that Wendt violated Section 8(a)(1)
    of the Act by refusing a unit employee’s request for a union
    representative during an investigative disciplinary interview.
    Next, on February 8, 2018, while negotiations for a
    collective-bargaining agreement with the Union were ongoing,
    Wendt temporarily laid off 10 unit employees. Before the
    layoffs, Voigt had made threatening comments toward pro-
    union employees, created an impression of surveillance of pro-
    union employees, and represented that employees who
    4
    supported the Union would be laid off. The Board held that
    Wendt violated Section 8(a)(5) and (1) of the Act by
    unilaterally laying off 10 unit employees in the absence of a
    bargaining impasse.
    Further, William Hudson, a highly skilled welder and
    active union leader, was one of the 10 unit employees
    temporarily laid off. He was also a member of the Union’s
    bargaining team. On April 6, 2018, two months after the
    layoff, Wendt recalled Hudson to work and exclusively
    assigned him to “the saw,” a task generally reserved for
    unspecialized workers, for over four months. Wendt assigned
    all other recalled welders, as well as certain temporary
    employees, to perform welding work. Wendt asserted that it
    assigned Hudson to saw work because Hudson had not
    operated the saw and needed experience. Additionally, Hudson
    observed that other recalled employees were working overtime,
    and so he also requested to work overtime. Wendt denied his
    requests multiple times, but granted overtime to other welders
    and at least one employee on a short-term saw work
    assignment. The Board found that Wendt’s decisions to
    exclusively assign Hudson to low-skilled saw work and deny
    him overtime were motivated by anti-union animus, in
    violation of Section 8(a)(3) and (1) of the Act.
    The next issue concerns Wendt’s administration of
    performance reviews and wage increases. Pursuant to its
    employee handbook, Wendt provides employees with
    performance reviews on an annual basis. In 2016, for example,
    Wendt provided annual performance reviews and wage
    increases to all employees—unit and non-unit—in the same
    time frame. Following the Union’s certification for collective
    bargaining purposes, Wendt evaluated non-unit employees and
    gave them wage increases in November and December 2017.
    In November 2017, the Union requested that Wendt provide
    5
    unit employees with their 2017 performance reviews based on
    its understanding of Wendt’s past practice of providing
    performance reviews for unit and non-unit employees alike at
    roughly the same time. Wendt failed to evaluate unit
    employees until April 2018, delaying unit employees’
    performance evaluations and accompanying wage increases for
    about six months.
    During negotiations in May 2018, Wendt proposed a 3.42
    percent wage increase for unit employees, retroactive to April
    8, 2018, the date Wendt completed unit employees’
    evaluations. The Union, however, counter-proposed a 4
    percent wage increase, retroactive to October 2017, to account
    for the six-month delay of reviews. Wendt told the Union that
    its offer of a 3.42 percent wage increase would expire if the
    Union did not accept it by June 20, 2018. The Union accepted
    the offer but stated that it wanted to continue bargaining for the
    increased percentage and retroactivity to October 2017.
    Wendt’s chief negotiator replied, “Fair enough. You can
    bargain for that.” J.A. 127. Later, when the Union renewed its
    request to bargain for retroactive wage increases, Wendt
    responded that the parties had already reached an agreement,
    referencing the Union’s acceptance of Wendt’s offer for a 3.42
    percent wage increase, retroactive to April 2018. The Union
    responded that there was no final agreement regarding the
    retroactive wage increases and reminded Wendt that it
    specifically reserved the right to bargain for further retroactive
    pay. Wendt refused to bargain with the Union. The Board
    ruled that Wendt violated Section 8(a)(3) and (1) when it
    delayed performance reviews, and thereby deprived unit
    employees of wage increases for approximately six months,
    and violated Section 8(a)(5) and (1) when it failed to afford the
    Union an opportunity to bargain over providing annual
    performance reviews and wage increases from about
    6
    November          2017        through        April        2018.
    Finally, Wendt posted openings for three shop supervisor
    positions—one recently vacant position and two newly created
    positions—and promoted three unit employees into the
    positions. Wendt did not hire anyone to fill the three vacant
    unit roles. Instead, the new supervisors were required to
    continue doing some of the unit work from their previous roles,
    and temporary employees and contractors completed the rest.
    The Union requested to bargain with Wendt over the newly
    created supervisor positions, but Wendt refused. The Board
    held that Wendt violated Section 8(a)(5) and (1) when it
    unilaterally removed unit work and transferred it to three newly
    appointed shop supervisors without bargaining with the Union.
    II.
    The NLRA guarantees employees “the right to self-
    organization, to form, join, or assist labor organizations, to
    bargain collectively through representatives of their own
    choosing, and to engage in other concerted activities for the
    purpose of collective bargaining or other mutual aid or
    protection . . . .”

    On petitions for review of an NLRB order, “we must
    uphold the judgment of the Board unless its findings are
    unsupported by substantial evidence, or it acted arbitrarily or
    otherwise erred in applying established law to the facts of the
    case.” Novato Healthcare Ctr. v. NLRB,

    , 1100
    (D.C. Cir. 2019) (citing Spurlino Materials, LLC v. NLRB, 
    805 F.3d 1131
    , 1136 (D.C. Cir. 2015); Bally’s Park Place, Inc. v.
    NLRB, 
    646 F.3d 929
    , 935 (D.C. Cir. 2011)). “Substantial
    evidence ‘means such relevant evidence as a reasonable mind
    might accept as adequate to support a conclusion.’” NLRB v.

    Universal Camera Corp. v. NLRB, 
    340 U.S. 474
    , 477 (1951)).
    We must therefore “affirm the Board’s findings unless ‘no
    reasonable factfinder’ could find as it did.” Ingredion, 930
    F.3d at 514 (quoting Alden Leeds, Inc. v. NLRB, 
    812 F.3d 159
    ,
    165 (D.C. Cir. 2016)).
    We will take each of Wendt’s challenges in turn, starting
    with its argument that the Board’s finding of a Section 8(a)(1)
    violation in connection to the forklift incident involving
    Fricano was not supported by substantial evidence.
    A.
    Wendt first challenges the Board’s finding that it violated
    Section 8(a)(1) when it denied employee John Fricano a right
    to a union representative during a disciplinary interview. In
    National Labor Relations Board v. J. Weingarten, Inc., 
    420 U.S. 251
     (1975), the Supreme Court held that an employee has
    a right to union representation in an investigative interview
    when the employee reasonably believes the interview may
    result in discipline. 
    Id.
     at 256–62. We discussed the
    Weingarten rule’s elements and application in Circus Circus
    Casinos, Inc. v. National Labor Relations Board:
    To prove a Weingarten allegation, the general
    counsel must show (1) the employee made a
    valid request for a union representative to be
    present during an investigatory interview; (2)
    the employee reasonably believed the interview
    might result in disciplinary action; and (3) the
    employer compelled the employee to attend the
    interview without union representation.
    
    961 F.3d 469
    , 477 (D.C. Cir. 2020) (citations omitted).
    8
    As indicated, Wendt called in unit employee John Fricano
    for questioning on the forklift incident, denied his request to be
    accompanied by a union representative during the interview,
    and then suspended him for three days without pay.
    Substantial evidence supports the Board’s finding that
    Wendt violated Section 8(a)(1). First, when Wendt plant
    manager Voigt approached Fricano and told him to come to the
    office to answer questions about the forklift incident, he denied
    Fricano’s valid request for a union representative to be present
    during the interview. Voigt even told Fricano he did not need
    a representative because Voigt and the human resources
    official, Williams, just wanted to ask Fricano a few questions
    about the incident. Next, the record reflects that Fricano
    reasonably believed that the interview might result in
    discipline. For example, consider Wendt operations director
    Howe’s testimony about the moment he approached Fricano as
    he was about to paint the item while the forklift was in the
    painting booth. When Howe “asked [Fricano] if he felt that
    [what he was doing] was safe,” Fricano’s “eyes doubled in size
    as he glared at [Howe] and immediately began to accuse other
    people of telling him to do it.” J.A. 550–51. Moreover, Voigt
    called Fricano in for questioning just two days after the
    incident, so Fricano had reason to believe that he might face
    discipline during the meeting. The record therefore supports
    the Board’s finding that Fricano had reasonable cause to
    believe that the interview would result in disciplinary action
    against him and that Wendt compelled him to participate
    without the representation he requested. See Circus Circus
    Casinos, 961 F.3d at 477.
    Wendt’s argument that Fricano was not entitled to a
    Weingarten representative because it had already made the
    decision to discipline Fricano and only called the meeting to
    9
    inform him that he was being disciplined lacks merit and is
    belied by the record evidence. At the time of the interview,
    when Fricano entered the room, Williams handed Fricano a
    notice of unpaid suspension for three days for a safety code
    violation. Williams told him that he would be terminated if he
    committed another violation. Williams invited Fricano to
    respond to Wendt’s statement on the incident by checking a
    box on the disciplinary document indicating agreement or
    disagreement, signing his name, and leaving comments. Thus,
    contrary to Wendt’s argument, the “sole purpose of the meeting
    was [not] to deliver the warning to [Fricano].” Cf. Jackson
    Hosp. Corp. v. NLRB, 
    647 F.3d 1137
    , 1142 (D.C. Cir. 2011).
    Rather, as the Board acknowledged in its order, Wendt invited
    Fricano to respond to its assessment of Fricano’s wrongdoing.
    See Baton Rouge Water Works Co., 
    246 N.L.R.B. 995
    , 997
    (1979) (noting that if an employer informs “the employee of a
    disciplinary action and then seek[s] facts or evidence in support
    of that action” or “attempt[s] to have the employee admit his
    alleged wrongdoing or to sign a statement to that effect,” then
    “the employee's right to union representation . . . attach[es]”).
    We therefore sustain the Board’s ruling that Wendt violated
    Section 8(a)(1) of the Act.
    B.
    Next, Wendt contends that substantial evidence does not
    support the Board’s determination that it violated Section
    8(a)(3) and (1). Wendt disputes the Board’s finding that it
    assigned Hudson to low-skilled saw work and denied him
    overtime because of his union activities.
    Section 8(a)(3) “makes it an unfair labor practice for an
    employer ‘by discrimination in regard to hire or tenure of
    employment or any term or condition of employment to
    encourage or discourage membership in any labor
    10
    organization[.]’” Napleton 1050, Inc. v. NLRB, 
    976 F.3d 30
    ,
    34 (D.C. Cir. 2020) (quoting 
    29 U.S.C. § 158
    (a)(3)) (alteration
    in original). “[A] violation of § 8(a)(3) constitutes a derivative
    violation of § 8(a)(1).” Metro. Edison Co. v. NLRB, 
    460 U.S. 693
    , 698 n.4 (1983). “To prove a § 8(a)(3) violation, the Board
    must first demonstrate that anti-union animus motivated the
    employer to take an adverse employment action.” Fortuna
    Enters., LP v. NLRB, 
    665 F.3d 1295
    , 1303 (D.C. Cir. 2011).
    The Board applies the two-part Wright Line test when
    evaluating claims of anti-union animus. See Tasty Baking Co.
    v. NLRB, 
    254 F.3d 114
    , 125 (D.C. Cir. 2001) (citing Wright
    Line, 
    251 N.L.R.B. 1083
    , 1089 (1980)).
    Under the Wright Line test, the Board must “determine
    whether an unlawful motive underlay an adverse action taken
    by an employer.” Napleton 1050, 976 F.3d at 40. First, “the
    General Counsel must make a prima facie showing sufficient
    to support the inference that protected . . . conduct was a
    motivating factor behind the discipline.” Fort Dearborn Co. v.
    NLRB, 
    827 F.3d 1067
    , 1072 (D.C. Cir. 2016) (citation and
    internal quotation marks omitted). “Relevant factors in
    determining an employer’s motive include the employer’s
    knowledge of the employee’s union activities, the employer’s
    hostility toward the union, and the timing of the employer’s
    action.” Ozburn-Hessey Logistics, LLC v. NLRB, 
    833 F.3d 210
    , 218 (D.C. Cir. 2016) (citations and internal quotation
    marks omitted). If the General Counsel makes a prima facie
    showing, then at step two, “the burden shifts to the company to
    show that it would have taken the same action in the absence
    of the unlawful motive.” Tasty Baking, 
    254 F.3d at 126
    . The
    employer “avoid[s] an unfair labor practice finding by showing
    by a preponderance of evidence that the worker would have
    [faced an adverse employment action] even if he had not been
    involved with the union.” See Davis Supermarkets, Inc v.
    NLRB, 
    2 F.3d 1162
    , 1167 (D.C. Cir. 1993) (citation and
    11
    internal quotation marks omitted). Importantly, this Court’s
    review “of the Board’s conclusions as to discriminatory motive
    is even more deferential” than the “substantial evidence
    standard” because “most evidence of motive is circumstantial.”
    Fort Dearborn Co., 827 F.3d at 1072 (citations and internal
    quotation marks omitted). And “[t]he court accepts the ALJ’s
    credibility determinations as adopted by the Board, unless they
    are patently unsupportable.” Id. (citations and internal
    quotation marks omitted).
    Wendt argues that under the Wright Line test, the NLRB
    General Counsel failed to establish a prima facie case of
    discrimination because it did not show a causal relationship
    between Hudson’s protected union activities and Wendt’s
    decisions regarding Hudson’s employment. Wendt argues that
    the Board’s finding of anti-union animus hinges on plant
    manager Voigt’s threatening comments to pro-union
    employees even though there is no record evidence of Voigt
    making such comments to Hudson specifically. Moreover,
    Wendt says that even if the General Counsel did establish a
    prima facie case, Wendt met its burden of showing that it
    would have taken the same action against Hudson absent his
    protected union activity because it had a “business need” to
    assign Hudson to saw work. Pet’r’s Br. 20–21.
    The Board’s findings are supported by substantial
    evidence. First, the Board had ample evidence to support its
    conclusion that the General Counsel made a prima facie
    showing that anti-union animus was a motivating factor in
    Wendt’s decision to assign Hudson to the saw and deny him
    overtime. The record reflects that Voigt made “repeated threats
    . . . [and] expressed a general threat to all employees,”
    including “threatening to target union supporters for layoff and
    to get rid of ‘a lot of’ shop employees.” J.A. 106–07. Turning
    to Wendt’s argument that the Board improperly considered
    12
    Voigt’s anti-union conduct and comments, even though he
    never made anti-union comments toward Hudson, we conclude
    that the Board did not err when it considered this evidence.
    In Parsippany Hotel Management Co. v. NLRB, 
    99 F.3d 413
     (D.C. Cir. 1996), we addressed an employer’s argument
    that a general manager’s anti-union speech is not evidence of
    anti-union animus. 
    Id. at 423
    . The Court rejected this
    argument and explained that “[a] company’s open hostility
    toward Union activity,” including a manager’s anti-union
    speech, is “clearly sufficient to establish anti-union animus on
    the part of that company.” 
    Id.
     (citation and internal quotation
    marks omitted). The Court also rejected the employer’s
    assertion that the manager’s speech “did not establish anti-
    union animus because [the manager] was not involved in the
    discharge and discipline of [the employee].” 
    Id.
     Accordingly,
    the Court determined that the General Counsel established a
    prima facie case of anti-union animus under the Wright Line
    test. 
    Id. at 424
    .
    Our ruling in Parsippany undermines Wendt’s assertion
    that the Board’s decision to consider Voigt’s anti-union
    comments was erroneous. See 
    id.
     at 423–24. As the Board
    reasoned, Voigt’s comments “expressed a general threat to all
    employees”—including threats to lay off union supporters like
    Hudson. Accordingly, it was appropriate for the Board to
    consider Voigt’s anti-union animus. J.A. 68–69.
    Furthermore, ample record evidence supports the Board’s
    conclusion that Wendt singled Hudson out from “the other laid-
    off welders by denying only him any welding work and any
    overtime work opportunities, and instead making him the sole
    welder assigned exclusively to the low-skill saw.” J.A. 69.
    Wendt also had knowledge of Hudson’s status as a Union
    leader: Hudson was on the Union negotiation committee,
    13
    attended almost all of the bargaining sessions, was the Union’s
    observer at the election, regularly wore Union apparel at work,
    and was nicknamed “The President” because he organized
    most of the employees. J.A. 82 & n.16. All in all, Wendt’s
    “knowledge of [Hudson’s] union activities” and Wendt’s
    “hostility toward the union,” as evidenced by Voigt’s anti-
    union comments, are substantial evidence that Hudson’s
    protected activities were a motivating factor in Wendt’s
    adverse action toward him. See Fort Dearborn Co., 827 F.3d
    at 1072 (citation and internal quotation marks omitted). And
    the fact that Hudson was singled out for this low-skilled work
    while other welders were permitted to continue welding
    negates Wendt’s defense that it would in any event have
    selected Hudson for the saw work for purely business reasons,
    wholly apart from its anti-union animus against him.
    There is likewise no merit to Wendt’s claim that an
    inference of unlawful motive is unwarranted because it
    contemporaneously granted overtime to another union
    supporter. “An employer’s failure to discriminate against
    every union supporter does not disprove a conclusion that it
    discriminated against one of them.” Handicabs, Inc., 
    318 N.L.R.B. 890
    , 897–98 (1995), enforced, 
    95 F.3d 681
     (8th Cir.
    1996). Accordingly, the Board’s finding, that Wendt violated
    Section 8(a)(3) and (1) of the NLRA, is supported by
    substantial evidence in the record.
    C.
    Next, Wendt challenges the Board’s finding that it violated
    Section 8(a)(5) and (1) of the Act when it removed three
    positions from the bargaining unit in connection to its
    promotion of three unit employees into shop supervisor roles.
    Wendt argues that the Board’s findings are not supported by
    substantial evidence because the total loss of unit work
    14
    attributable to the three promotions amounted to less than one
    full-time position. Thus, Wendt contends that it was not a
    material and substantial change that triggered its obligation to
    bargain with the Union. Wendt also argues that its unilateral
    transfer of the work from the vacant unit positions to non-unit
    employees and to shop supervisors was consistent with past
    practice.
    “Section 8(a)(5) provides that it is ‘an unfair labor practice
    for an employer to refuse to bargain collectively with the
    representatives of his employees.’” Ingredion, 930 F.3d at 513
    (quoting 29 U.S.C § 158(a)(5)). “Because a refusal to bargain
    necessarily interferes with bargaining, ‘an employer who
    violates section 8(a)(5) also, derivatively, violates section
    8(a)(1).’” Ingredion, 930 F.3d at 513 (quoting Exxon Chem.
    Co. v. NLRB, 
    386 F.3d 1160
    , 1164 (D.C. Cir. 2004)).
    Substantial evidence supports the Board’s finding that
    Wendt failed to show that its unilateral removal and transfer of
    unit work was consistent with an established past practice and
    its holding that Wendt’s conduct violated Section 8(a)(5) and
    (1) of the Act.
    We have held that the “transfer of bargaining unit work to
    managers and assistant managers” triggers “the employer’s
    duty to bargain where the change results in the loss of
    bargaining unit jobs.” See Regal Cinemas, Inc. v. NLRB, 
    317 F.3d 300
    , 307 (D.C. Cir. 2003). In Regal Cinemas, this Court
    upheld the Board’s ruling that Regal’s transfer of duties of
    union-represented projectionists to managers and assistant
    managers, without bargaining with the unions, violated Section
    8(a)(5) and (1) of the NLRA. 
    Id.
     at 302–03. Even though the
    duties of a projectionist are limited, as “[t]he work required of
    a projectionist prior to the start of a film . . . takes
    approximately five to ten minutes,” 
    id. at 303
    , we rejected
    15
    Regal’s argument that “the assignment of the few . . . minimal
    tasks [of union projectionists] to managers and assistant
    managers cannot . . . be characterized as a transfer of work.”
    
    Id. at 307
     (internal quotation marks and citation omitted). Even
    when minimal, where “the change results in the loss of
    bargaining unit jobs,” it is a mandatory subject of bargaining.
    
    Id. at 307
    .
    In this case, as the Board noted, Wendt’s removal of three
    unit positions and transfer of their work to non-unit employees
    and to the newly appointed supervisors amounted to a loss of
    “1,372 man-hours from the unit annually, which is more than
    26 hours of unit work lost each week.” J.A. 72. Accordingly,
    the amount of unit work lost in this case far exceeded the
    amount lost in Regal Cinemas. 
    317 F.3d at
    303–07. Thus, we
    are not persuaded by Wendt’s assertion that there was not a
    material and significant loss of unit work as a result of its
    unilateral removal and transfer of unit work. Pet’r’s Br. 43–44.
    The Board’s findings were supported by substantial evidence.
    Turning next to Wendt’s past practice argument, Wendt
    argues that the Board’s decision was not supported by
    substantial evidence because Wendt established a past practice
    of having supervisors perform unit work. Wendt obfuscates
    the grounds on which the Board rested its finding of an NLRA
    violation. As the Board noted, “[t]he issue is not whether
    [Wendt] may continue a past practice of supervisors
    performing some unit work, but whether [Wendt], when it
    promoted the three shop employees to supervisory positions,
    effectively removed their work from the unit entirely and did
    not replace it.” J.A. 72. In any event, Wendt did not present
    any evidence that it had a past practice of unilaterally removing
    unit positions, let alone a past practice of doing what it did here:
    unilaterally eliminating and transferring unit work. In sum, we
    16
    sustain the Board’s rejection of Wendt’s past practice argument
    because it is supported by substantial evidence.
    D.
    Next, Wendt challenges the Board’s holding that it
    violated the Act by delaying wage increases and performance
    reviews and refusing to bargain with the Union over retroactive
    wage increases. Wendt contends that the Board’s ruling is
    erroneous, in part because it conflicts with another recent
    NLRB ruling, and also because it is unsupported by substantial
    evidence. The Board ruled that Wendt violated Section 8(a)(3)
    and (1) by failing to provide annual performance reviews and
    accompanying wage increases to bargaining unit employees,
    thereby depriving them of wage increases for approximately
    six months, and violated Section 8(a)(5) and (1) by failing to
    afford the Union an opportunity to bargain.
    Substantial evidence in the record supports the Board’s
    findings that Wendt violated the Act when it delayed unit
    employees’ performance reviews and wage increases and
    refused to bargain with the Union. The record reflects that
    Wendt told the Union both that it could accept the offer of a
    3.42 percent wage increase that applied retroactively to April
    2018 before it expired and that it could continue bargaining for
    a 4 percent wage increase, retroactive to October 2017. Wendt
    then reneged on its word and refused to bargain.
    Wendt also argued that the Board failed to apply the
    “contract coverage” standard to determine whether it was
    obligated to bargain with the Union on a matter covered by an
    agreement between itself and the Union, pursuant to the
    Board’s ruling in MV Transportation, Inc., 368 N.L.R.B. No.
    66 (Sept. 10, 2019). The Board decided MV Transportation
    several months before it issued the ruling underlying this
    17
    petition. But Wendt never raised the “contract coverage”
    argument before the Board. Consequently, this challenge is
    forfeited and we lack jurisdiction to consider it. Pet’r’s Br. 37;
    Spectrum Health—Kent Cmty. Campus v. NLRB, 
    647 F.3d 341
    ,
    348 (D.C. Cir. 2011).
    E.
    Finally, Wendt argued before the Board that its unilateral
    temporary layoff of 10 unit employees in February 2018 was
    consistent with past practice.
    In its opening brief, Wendt contends that it has historically
    implemented layoffs during economic slowdowns, including in
    2001, 2002, 2003, 2009, and 2015, when it laid off employees
    “based on decreases in customer orders and/or a decrease in
    available work.” Pet’r’s Br. 9–10. The Board concluded that
    Wendt failed to meet its burden of establishing the past practice
    affirmative defense.
    The Board noted that Wendt had previously implemented
    temporary layoffs in 2001 and 2009 but held that Wendt’s “use
    of temporary layoffs twice in 17 years falls well short of
    establishing a regular and consistent practice sufficient to
    privilege unilateral action.” J.A. 70. The Board also noted that
    Wendt’s 2009 layoff affected both non-unit and unit employees
    in equal numbers, whereas the 2018 layoff at issue here only
    affected unit employees. Accordingly, the Board ruled that
    Wendt did not consistently and regularly implement temporary
    layoffs affecting unit employees and thus unit employees could
    not expect or recognize the contested action as a continuation
    of past practice.
    Wendt argues that the Board inexplicably focused on the
    number of layoffs Wendt has implemented, rather than
    Wendt’s practice of laying off employees during economic
    18
    slowdowns. In doing so, Wendt says, the Board strayed from
    its past precedent. See Raytheon Network Centric Sys., 365
    N.L.R.B. No. 161, at *21 (Dec. 15, 2017) (“an employer’s past
    practice constitutes a term and condition of employment that
    permits the employer to take actions unilaterally that do not
    materially vary in kind or degree from what has been
    customary in the past”); Mike-Sell’s Potato Chip Co., 368
    N.L.R.B. No. 145, at *6 (Dec. 16, 2019) (“To establish the
    existence of a past practice, it is enough to show that frequent,
    recurrent, and similar actions have been taken . . . .”) (emphasis
    omitted).
    We do not believe the Board adequately addressed
    Wendt’s past practice argument. If the Board had considered
    all five of the past layoffs that Wendt says comprise its past
    practice, then the Board may have had grounds to conclude that
    Wendt lacked a past practice of layoffs that occurred with
    sufficient regularity and frequency to privilege Wendt to act
    unilaterally. But the Board considered only a subset of the
    layoffs Wendt identified without adequately explaining the
    materiality of its distinctions between those considered and
    those excluded. Because our review is limited to the grounds
    on which the Board ruled, see Temple Univ. Hosp., Inc. v.
    NLRB, 
    929 F.3d 729
    , 734 (D.C. Cir. 2019), we remand for the
    Board to complete its explanation of its distinctions or to
    consider each of the identified layoffs as materially similar in
    its assessment of whether Wendt’s claimed past practice
    “occurred with such regularity and frequency that employees
    could reasonably expect the practice to reoccur on a consistent
    basis.” Mike-Sell’s Potato Chip Co., 368 N.L.R.B. No. 145, at
    *4 (Dec. 16, 2019).

    III.
    Wendt also challenges the Board’s imposition of remedies
    that it contends “compel the outcome of the bargaining
    process.” Pet’r’s Br. 3. We defer to the Board’s remedial
    determinations, subject to appropriate challenges in the
    compliance phase. RAV Truck & Trailer Repairs, Inc. v.
    NLRB, 
    997 F.3d 314
    , 329 (D.C. Cir. 2021).
    IV.
    Consistent with the foregoing discussion, the petition for
    review is granted in part and denied in part. The Board’s cross-
    application for enforcement is likewise granted in part and
    denied in part. We remand the case for further consideration
    of whether Wendt’s temporary layoff of unit employees in
    February 2018 was privileged by past practice. We summarily
    enforce the unchallenged portions of the Board’s order. Allied
    Mech. Servs., Inc. v. NLRB, 
    668 F.3d 758
    , 765 (D.C. Cir.
    2012).
    Also, the Board inadvertently included two dismissed
    allegations in adopting the ALJ’s Section 8(a)(1) violations.
    Wendt did not challenge those errors, but the Board has
    requested that in enforcing the Board’s order, we correct those
    parts of the order and notice. Resp.’s Br. 12 n.2. Pursuant to
    the Board’s request, we modify the order to exclude references
    to the two dismissed allegations and direct the Board to submit
    to the Court a proposed judgment conforming to this opinion.
