    Circuit Judge RAO.
    ROGERS, Circuit Judge: The National Labor Relations
    Board determined that Pacific Maritime Association
    (“Pacific”) and Long Beach Container Terminal (“Long
    Beach”) committed two distinct unfair labor practices in
    violation of the National Labor Relations Act when they
    applied disciplinary provisions of one employee’s collective
    bargaining agreement for resolving discrimination complaints
    to an employee represented by a different union under a
    collective bargaining agreement with different procedures and
    remedies. Pacific and Long Beach (hereinafter referred to
    together as “The Employers”), seek to avoid their statutory
    obligations by contending that they reasonably interpreted their
    contractual agreement with the disciplined employee to permit
    the use of procedures and imposition of penalties that were not
    included in this agreement, and their disciplinary action did not
    unilaterally change the terms and conditions of the disciplined
    employee’s employment. In view of the plain text of the
    Employers’ agreement that covered the disciplined employee
    and the record before the Board, we deny their petitions for
    review and grant the Board’s cross-applications for
    enforcement of its Order.
    I.
    Pacific Maritime Association (“Pacific”) and Long Beach
    Container Terminal (“Long Beach”) are involved in shipping,
    longshore, and cargo-handling industries at ports on the Pacific
    coast. Pacific is a mutual benefit corporation that serves as the
    multi-employer bargaining representative for its employer
    members, with the primary purpose of negotiating, executing,
    and administering collective bargaining agreements (“CBAs”).
    One of its members, Long Beach, operates a marine container
    3
    terminal at the Port of Long Beach and employs both watchmen
    and marine clerks. Each classification of employee is
    represented by a different union, and Pacific has entered into
    separate agreements with each union. We begin with a
    summary of those CBAs.
    A.
    Watchmen at the Port of Long Beach have long been
    represented by ILWU, Warehouse, Processing and Distribution
    Workers Union, Local 26 (“Local 26”).                      Under the
    Watchmen’s Agreement, Local 26 and Pacific jointly operate a
    dispatch hall that refers watchmen to work for Pacific’s
    members. Article 18 establishes a procedure for addressing
    disciplinary issues and other disputes arising under the
    Agreement. Article 16 of the Agreement broadly prohibits
    discrimination against “any person” on the basis of “race,
    color, national origin . . . or political beliefs . . . .” Pursuant to
    Article 18(C), a Joint Labor Relations Committee of employer
    and union representatives establishes the rules and penalties
    governing watchmen’s conduct; employers retain an
    unrestricted right of discipline for five offenses. Otherwise,
    Article 18(D)(1) requires the employer to “attempt to notify
    and discuss the alleged incident with the individuals involved”
    and Local 26. “Following a good faith discussion with the
    Union, or inability to contact the designated Union
    representative within a reasonable time period,” the employer
    may file a formal complaint, Article 18(D)(1), or request a
    meeting with the Joint Committee, Article 18(E). “If a
    satisfactory settlement cannot be reached” by the Joint
    Committee, then “either party may refer the matter” to the
    contractual Watchmen Arbitrator.
    Id. Rules control the
    arbitration process, including the parties’ selection of
    arbitrators, and rules also limit appeals.
    4
    Article 18(H) provides that the “grievance machinery” in
    the Watchmen’s Agreement “shall be the exclusive remedy
    with respect to any dispute arising under [it] and no other
    remedies shall be used by the Union, the Employer, or any
    covered employee until the grievance procedures have been
    exhausted.”      Where a disciplinary action affecting a
    watchman’s dispatch right is involved, Article 18(I) specifies
    that an employer complaint shall only be applicable “to the
    terminal where the complaint arose.” Article 21 states that no
    provision of the contract “may be amended, modified, changed,
    altered or waived, except by a written document executed by
    the parties hereto.”
    The marine clerks are represented by the International
    Longshore and Warehouse Union (“the International”). The
    Pacific Coast Longshore and Clerks’ Agreement (“Clerks’
    Agreement”) covers approximately 25,000 longshore workers
    and marine clerks at Pacific coast ports. This CBA contains its
    own mechanism for the signatory unions and employers to
    address disputes regarding covered longshore workers and
    marine clerks. Notably for present purposes, the Clerks’
    Agreement includes Section 13.2, which establishes a special
    grievance procedure for resolving allegations of discrimination
    or harassment. Under this streamlined procedure, an individual
    employee may file a complaint, which will be assigned directly
    to an arbitrator. The arbitrator must promptly schedule an
    evidentiary hearing to investigate the alleged incident. Within
    fourteen days after the hearing, the arbitrator shall issue a
    written decision that includes, as necessary, disciplinary
    penalties consistent with the guidelines in the Clerks’
    Agreement. The arbitrator’s decision is final, with only limited
    appeal. In addition to the broad prohibition on discrimination
    in Section 13.1, side agreements set forth rules of conduct and
    examples of conduct warranting discipline. In July 2014,
    Pacific and the International clarified, by letter of
    5
    understanding (“2014 LOU”), that Section 13.2 complaints
    may be brought against “other employees of [Pacific’s]
    member companies,” but those outside employees may not file
    Section 13.2 complaints.
    B.
    The events giving rise to the Board’s determination that
    the Employers had violated the Act began on March 28, 2017.
    Demetrius Pleas, a watchman represented by Local 26, and a
    marine clerk represented by the International had a work-
    related argument during which both men allegedly engaged in
    racial name-calling. At the time, Pleas was working for Long
    Beach. The two employees resolved the matter informally that
    day, but on March 30, 2017, the marine clerk filed a grievance
    against Pleas pursuant to Section 13.2 of the Clerks’
    Agreement. Long Beach informed Local 26 the next day that
    it was investigating the incident and intended, if necessary, to
    pursue discipline against Pleas under Article 18(C) of the
    Watchmen’s Agreement. Long Beach ultimately concluded
    that there was insufficient evidence Pleas engaged in
    wrongdoing to warrant filing a formal Article 18 complaint, but
    warned Pleas that future incidents would be dealt with through
    the Watchmen Joint Committee process.
    Meanwhile, the Arbitrator assigned to the Section 13.2
    grievance scheduled a hearing for May 3, 2017. Counsel for
    Local 26 wrote Pacific that Local 26 was not bound by Section
    13.2 and neither Local 26 nor Pleas would participate in the
    hearing, and requested that Pacific not take any adverse action
    against Local 26 members based on these proceedings. Pacific
    responded by letter that Long Beach and the other Pacific
    employer members would implement whatever discipline the
    Arbitrator determined would be appropriate. Neither Pleas nor
    a Local 26 representative attended the arbitration hearing, but
    6
    representatives from Pacific and Long Beach did attend and
    actively participated. At the beginning of the hearing the
    Arbitrator stated that he did not “really have authority over Mr.
    Pleas” pursuant to the Clerks’ Agreement and that “it would be
    up to the Employer to enforce any decision if any if action was
    needed.” Arb. Hr’g Tr. 19–20 (May 3, 2017). Pacific made a
    statement that the “direct employer” (referring to Long Beach)
    “is prepared to implement any decision made by the
    Arbitrator,” and that Pleas (the watchman) “is subject to
    complaints under Section 13.2 of the [Clerks’ Agreement] as
    outlined in the 2014 LOU” between Pacific and the
    International. Arb. Dec. 3 (June 5, 2017).
    The Arbitrator proposed that Pleas be barred from working
    at Long Beach until a final decision was rendered. In his final
    decision, the Arbitrator found that Pleas had violated Section
    13.2 policies and should be suspended from working at all
    Pacific employer member terminals for twenty eight days, and
    also required to undertake an unpaid training video and to sign
    a statement pledging to abide by Section 13.2 policy before
    returning to work. See
    id. at 8.
    Local 26 appealed; the
    Arbitrator’s Order and Decision were sustained, rejecting
    Local 26’s jurisdictional argument. In July 2017, Pacific
    notified its employer members of Pleas’ suspension from
    working at terminals covered by the Clerks’ Agreement.
    Local 26 filed unfair labor practice charges against the
    Employers in May 2017, alleging that they had violated the Act
    by committing two theoretically distinct unfair labor practices
    in disciplining watchman Pleas under the Section 13.2
    procedure in the Clerks’ Agreement: (1) impermissibly
    modifying the Watchmen’s Agreement and (2) unilaterally
    imposing a new term and condition of employment without
    bargaining.    The Board affirmed the decision of an
    administrative law judge (“ALJ”) that the Employers had
    7
    violated Sections 8(a)(5) and (1) of the Act under either of the
    General Counsel’s alternative theories: when they applied
    Section 13.2 of the Clerks’ Agreement, to Pleas, an employee
    of the watchmen’s unit represented by Local 26 and covered by
    that unit’s Watchmen’s Agreement, and when they disciplined
    him pursuant to the Section 13.2 process. Pac. Mar. Ass’n, 
    367 NLRB No. 121
    , 
    2019 WL 1977314
    , at *1, 4–6 (May 2, 2019).
    The Employers were ordered to cease and desist, to rescind the
    suspension and make Pleas financially whole, and, among
    other things, to delete from their records any reference to his
    suspension. One Member dissented, arguing the Employers
    did not apply the Section 13.2 procedure since they did not file
    the complaint, they reasonably believed the Watchmen’s
    Agreement did not preclude imposing Section 13.2 discipline,
    and they did not unilaterally change the terms and conditions
    of Pleas’ employment because there was no consistent
    disciplinary practice. Pacific and Long Beach both petitioned
    for review of the Board’s Decision and Order. The Board filed
    cross-applications for enforcement of its Order.
    II.
    The Board determined that the Employers committed two
    distinct unfair labor practices: contract modification and
    unilateral change. These alternative grounds for the Board’s
    Decision involve distinct violations of the Act with different
    governing standards, defenses, and remedies. Bath Iron Works
    Corp., 
    345 N.L.R.B. 499
    , 501–03 (2005), enforced sub nom. Bath
    Marine Draftsmen’s Ass’n v. NLRB, 
    475 F.3d 14
    (1st Cir.
    2007). The Board has concluded that it may find an unlawful
    unilateral change, in addition or in the alternative, where it has
    also found an unlawful contract modification. See, e.g.,
    Comau, Inc., 
    364 NLRB No. 48
    , 
    2016 WL 3853834
    , at *4–6
    (July 14, 2016). Its counsel explains that “an employer’s
    actions may modify a provision ‘contained in’ a [CBA] while
    8
    also imposing a change to a mandatory bargaining subject
    where nothing in the contract ‘covers’ the employer’s right to
    act unilaterally.” Resp’ts’ Br. 22 (citations omitted).
    The Supreme Court has recognized that “the authority of
    the Board and the law of contract are overlapping, concurrent
    regimes,” and that “the Board may proscribe conduct which is
    an unfair labor practice even though it is also a breach of
    contract remediable as such by arbitration and in the courts.”
    NLRB v. Strong, 
    393 U.S. 357
    , 360–61 (1969). But neither the
    Supreme Court nor this court has spoken directly to the
    question whether the Board has the authority to proceed on
    different theories of violation based on the same set of facts.
    Nor need we do so today. The Employers challenge the
    Board’s findings of both statutory violations but they present
    no challenge to the application of both theories to the same set
    of facts. Therefore, the court has no occasion to decide whether
    both unfair labor practices can be properly found in cases of
    this sort and proceeds on the assumption the Board may do so.
    Turning to the Employers’ challenges, the scope of the
    court’s review of the Board’s decision is limited. As the
    Supreme Court has long acknowledged, Congress has
    determined that the Board has “the primary responsibility of
    marking out the scope . . . of the statutory duty to bargain,”
    Ford Motor Co. v. NLRB, 
    441 U.S. 488
    , 496 (1979), and “great
    deference” is due to the Board because determining whether a
    party has violated this statutory duty is “particularly within” the
    Board’s expertise, see Crowley Marine Servs., Inc. v. NLRB,
    
    234 F.3d 1295
    , 1297 (D.C. Cir. 2000) (quoting Local 13,
    Detroit Newspaper Printing & Graphic Commc’ns Union v.
    NLRB, 
    598 F.2d 267
    , 272 (D.C. Cir. 1979)); see also Ford
    
    Motor, 441 U.S. at 495
    . Consequently, this court “must sustain
    the Board’s decision ‘unless, reviewing the record as a whole,
    it appears that the Board’s factual findings are not supported by
    9
    substantial evidence, or that the Board acted arbitrarily or
    otherwise erred in applying established law to the facts at
    issue.’” S. Nuclear Operating Co. v. NLRB, 
    524 F.3d 1350
    ,
    1355 (D.C. Cir. 2008) (quoting Int’l All. of Theatrical & Stage
    Emps. v. NLRB, 
    334 F.3d 27
    , 31 (D.C. Cir. 2003)); Universal
    Camera Corp. v. NLRB, 
    340 U.S. 474
    , 477, 488 (1951); 29
    U.S.C. § 160(e). Reviewing courts may not “displace the
    Board’s choice between two fairly conflicting views,” even if
    the court “would justifiably have made a different choice” in
    the first instance. Universal 
    Camera, 340 U.S. at 488
    .
    Where a challenge is made to the Board’s interpretation of
    a contract, however, the court need give “no special deference”
    to “ultimate legal conclusions that rest on” the Board’s contract
    interpretations and interprets such contracts de novo. Local
    Union No. 47, Int’l Bhd. of Elec. Workers v. NLRB, 
    927 F.2d 635
    , 640–41 (D.C. Cir. 1991). The court applies “ordinary
    principles of contract law.” M&G Polymers USA, LLC v.
    Tackett, 
    574 U.S. 427
    , 435 (2015). Still, the court’s deference
    to the Board’s fact-finding extends to findings necessary to
    interpret the meaning of the contract, “including evidence of
    intent from bargaining history, and other factual findings on
    matters bearing on the intent of the parties,” as long as those
    findings are supported by substantial evidence in the record
    considered as a whole. StaffCo of Brooklyn, LLC v. NLRB, 
    888 F.3d 1297
    , 1302 (D.C. Cir. 2018) (citations and internal
    quotations marks omitted).
    A.
    An employer violates Sections 8(a)(5) and (1) of the Act
    by modifying terms and conditions of employment established
    in a CBA. 29 U.S.C. §§ 158(a)(1), (5), 158(d). Because the
    unfair labor practice question derives from an employer’s
    statutory duty to bargain, a midterm modification is unlawful
    10
    only if it involves a mandatory subject of bargaining for which
    the employer was required to bargain in the first place. Allied
    Chem. & Alkali Workers of Am., Local Union No. 1 v.
    Pittsburgh Plate Glass Co., 
    404 U.S. 157
    , 185–88 (1971).
    Disciplinary procedures are a mandatory subject of bargaining.
    See, e.g., El Paso Elec. Co., 
    355 N.L.R.B. 428
    , 453 (2010),
    enforced, 
    681 F.3d 651
    , 662–64 (5th Cir. 2012).
    The Board has recognized that an employer has not
    violated Section 8(a)(5) by modifying terms and conditions of
    employment under a CBA where the employer has a “sound
    arguable basis” for its interpretation of a contract and it is not
    motivated by animus or bad faith. Bath Iron 
    Works, 345 N.L.R.B. at 502
    . This exception has limits: no “sound arguable basis”
    in support of an employer’s purported interpretation of the
    contract can exist where, that interpretation runs “counter to the
    clear intention of the parties,”
    id., or the contract
    “cannot be
    colorably interpreted to permit” the employer’s interpretation,
    MV Transp., Inc., 
    368 NLRB No. 66
    , 
    2019 WL 4316958
    , at
    *30 (Sept. 10, 2019).
    The Employers contend that they reasonably believed
    enforcing Section 13.2 of the Clerks’ Agreement against
    watchman Pleas was consistent with the Watchmen’s
    Agreement under which Pleas was covered. In their view, they
    did not modify the Article 18 procedures because no employer
    had filed the complaint as is contemplated by the Watchmen’s
    Agreement; rather a marine clerk covered by the Clerk’s
    Agreement filed the complaint. So, in their view, it was
    reasonable to interpret Article 18(D) regarding exhaustion
    requirements to apply only in cases in which an employer files
    a complaint. For the same reasons, they contend that there was
    no modification of Article 18(H), which provides that Article
    18’s grievance procedures are the exclusive remedy with
    respect to any dispute arising under the Watchmen’s
    11
    Agreement, because the dispute was initiated by the marine
    clerk and arose under the Clerks’ Agreement.
    But as the Board concluded, Article 18 of the Watchmen’s
    Agreement cannot be colorably interpreted to permit the
    Employers to unilaterally impose an alternative disciplinary
    procedure contrary to the exclusive procedure in that CBA, or
    to affirmatively grant the Employers the right to impose
    alternative disciplinary procedures unilaterally. First, the
    Employers’ view that Article 18 of the Watchmen’s Agreement
    did not limit their ability as employers to discipline Pleas for
    racial harassment is implausible on the face of the plain terms
    of the CBA. Article 18(H) expressly limits the Employers’
    ability to discipline employees “with respect to any dispute
    arising under the [Agreement]” unless the “grievance
    procedures have been exhausted.” Pleas’ alleged misconduct
    arose under the Agreement — specifically, Article 16’s anti-
    discrimination     provision,     which     broadly     prohibits
    discrimination against “any person” on the basis of “race,
    color, national origin, religious or political beliefs, sex, age,
    Veteran’s status, or disability.” Given the plain express terms
    of the Watchmen’s Agreement, an employer who seeks to
    discipline a covered employee for conduct prohibited by
    Article 16, must exhaust the grievance procedures in Article 18
    before pursuing other disciplinary remedies. See Pac. Mar.
    Ass’n, 
    367 NLRB No. 121
    , 
    2019 WL 1977314
    , at *5 & n.18,
    20. Such procedures include filing a complaint after attempting
    to informally resolve the dispute with Local 26, Article
    18(D)(1), or meeting with the Joint Committee and if a
    satisfactory settlement cannot be reached, referring the matter
    to the Watchmen Arbitrator, Article 18(E). The Employers did
    neither, and Long Beach expressly acknowledged the
    applicability of Article 18 procedures in declining to file a
    complaint against Pleas. The employers, therefore, could not
    reasonably conclude that, without first exhausting these
    12
    procedures, enforcing Section 13.2 of the Clerks’ Agreement
    against watchman Pleas was consistent with the Watchmen’s
    Agreement under which he was covered.
    The Employers press on, contending that Article 18(C)
    affirmatively grants employers the right to unilaterally
    discipline Pleas for racial harassment. This too is facially
    implausible. The plain text of Article 18(C) limits the
    employers’ unrestricted right of discipline to the specific
    offenses involving “intoxication, pilferage, assault,
    incompetency, or failure to perform work as directed.” Pleas’
    misconduct did not fall within these five offenses. Reading
    Article 18(C) to provide the employers an open-ended right to
    unilaterally discipline, as the Employers do, would effectively
    render the enumeration of offenses superfluous and Article
    18’s established disciplinary procedures largely meaningless.
    With Article 18(H) so understood, the Employers lacked a
    sound arguable basis for interpreting the CBA to permit their
    disciplinary action. Stark differences between the exclusive
    Article 18 grievance procedures and the Section 13.2 procedure
    applied by the Employers compel this conclusion. In a contract
    modification case, the dispositive issue is whether the
    Employers “had a ‘sound arguable basis’ for [their] actions,”
    Bath Iron 
    Works, 345 N.L.R.B. at 503
    . Here, the Employers
    interpreted their CBA with Local 26 to permit a marine clerk,
    covered by a different CBA, to refer his dispute with Pleas to
    arbitrators identified under the special Section 13.2 Grievance
    process and to permit the Employers to impose the Arbitrator’s
    discipline that exceeded the discipline allowed under the CBA
    that covered Pleas, and to do so without first exhausting the
    Article 18 procedures. The Employers’ conduct in imposing
    discipline was inconsistent with the exclusive provisions of
    Article 18, such as Article 18(E), which provides that the
    Employers may refer grievances to the “Watchmen Arbitrator,”
    13
    who is jointly selected and appointed by the Employers and
    Local 26, if a satisfactory settlement cannot be reached with the
    Joint Committee. Even if the marine clerk could properly file
    a complaint against watchman Pleas under Section 13.2, that
    did not mean the Employers could ignore their CBA with Local
    26 that covered Pleas. Therefore, they fail to show that the
    Board erred in rejecting their attempt to come within the scope
    of the sound arguable basis exception for contract
    interpretation.
    Second, the Employers maintain that the basic premise of
    the Board’s Decision, that they applied Section 13.2 against
    Pleas, is belied by the record. It is true that the Section 13.2
    procedures were initially invoked and pursued by the marine
    clerk, and not initiated by an employer. But the Board’s
    finding that the Employers actively participated before, during,
    and after the Section 13.2 arbitration hearing is supported by
    substantial evidence in the record considered as a whole. That
    evidence effectively rendered the marine clerk’s complaint the
    Employers’ complaint. Long Beach suggests it merely
    observed the arbitration proceeding and did not enforce the
    Arbitrator’s order. But at the hearing, Pacific represented to
    the Arbitrator, without objection, that Long Beach was Pleas’
    direct employer and stood ready to carry out any discipline
    recommended by the Arbitrator, and that Pleas was subject to
    the Section 13.2 procedures under the 2014 LOU between
    Pacific and the International. Participating in this Section 13.2
    arbitration proceeding was inconsistent with the terms of Pleas’
    Watchmen’s Agreement for addressing discrimination
    complaints. Furthermore, the Employers “implemented the
    resulting discipline,” Pet’rs’ Br. 47, by notifying all member
    terminals of Pleas’ suspension. That action, among others,
    resulted in penalties beyond those authorized under the
    Watchmen’s Agreement. For example, when Pleas was
    dispatched in July 2017 for a job at Hanjin Terminal, a covered
    14
    terminal under the Watchmen’s Agreement, he was ordered to
    leave.
    Third, the parties’ bargaining history and past practice
    further support the Board’s conclusion that the plain language
    of the Watchmen’s Agreement does not permit or authorize the
    Employers to discipline a Local 26 watchman using the special
    Section 13.2 procedure. In evaluating an employer’s sound
    arguable basis, the Board may examine “both the contract
    language itself and relevant extrinsic evidence,” such as
    bargaining history or past practice to determine the parties’
    intent, Knollwood Country Club, 
    365 NLRB No. 22
    , 
    2017 WL 1088796
    , at *1 (Mar. 8, 2017), and the Board has repeatedly
    relied on extrinsic evidence to support its sound arguable basis
    analysis, see, e.g.
    , id. at *1
    & n.8; see also ADT, LLC, 
    369 NLRB No. 31
    , 
    2020 WL 996271
    , at *5 & n.10 (Feb. 27, 2020);
    see also Comau, 
    364 NLRB No. 48
    , 
    2016 WL 3853834
    , at *5
    & n.16. The Board’s analysis here is in line with its precedent.
    The Board first determined that the “clear language” of Article
    18 prohibited the Employers’ disciplinary action and then
    explained how the parties’ past practice and bargaining history
    supported this finding. Pac. Mar. Ass’n, 
    367 NLRB No. 121
    ,
    
    2019 WL 1977314
    , at *5.
    There is substantial evidence to support the Board’s
    finding that Local 26 consistently rejected the Employers’
    proposals to incorporate procedures similar to a Section 13.2
    procedure into the Watchmen’s Agreement.               During
    negotiations in 2008 and 2014, the Employers proposed that a
    Section 13.2 procedure be added to the Watchmen’s
    Agreement and Local 26 repeatedly rejected these proposals.
    The Employers suggest that the Board has mischaracterized the
    record evidence because the parties never bargained over
    whether a non-watchman could use Section 13.2 to accuse a
    watchman of workplace harassment. Yet evidence credited by
    15
    the ALJ indicated that in October 2014 Pacific proposed to
    amend Article 16 to allow “any employee” to file a Section
    13.2 type grievance, General Counsel Ex. 5 (Employer
    Proposals: Article 16 (Oct. 8, 2014)) (emphasis added), and
    Local 26 rejected this proposal.
    There also is substantial evidence to support the Board’s
    finding that the parties have historically used Article 18
    procedures to resolve complaints of worker-versus-worker
    harassment. Sometimes this has been done informally with
    Local 26; other times it has been done through the formal
    complaint process. In the instant case, Long Beach notified
    Local 26 of its investigation into the discrimination allegations,
    and later issued Pleas an informal warning that future such
    occurrences would be resolved through the Article 18
    disciplinary process. Long Beach’s general manager testified
    that he had had informally resolved at least two dozen similar
    harassment complaints by issuing warning letters. In 2016,
    when Long Beach filed a formal Article 18 complaint against
    a watchman accused of harassing another watchman in
    violation of Article 16, the matter was resolved by the Joint
    Committee.
    Still, the Employers maintain that the evidence fails to
    support the Board’s position that Article 18 is the exclusive
    means for addressing these types of complaints. Putting aside
    the fact that Article 18(H) clearly states as much, the
    Employers point to no record evidence that the parties intended
    for the Employers to have a unilateral right to enforce Section
    13.2 against covered watchmen accused of discrimination. It
    is undisputed that the parties have not previously resolved
    worker-versus-worker harassment allegations in this way. The
    Board could properly conclude, therefore, that the Employers
    had no sound arguable basis to believe that their Section 13.2
    16
    disciplinary action was consistent with the Watchmen’s
    Agreement.
    Fourth, the Employers maintain that Local 26 is not
    entitled to override the Employers’ agreements with other
    unions and other workers’ rights under these agreements. They
    misconstrue federal labor law and principles of contract law.
    The Act establishes a system of exclusive collective-bargaining
    representation in which employers are statutorily obligated to
    bargain with their employees’ chosen representative over
    subjects such as employee disciplinary procedures. See 29
    U.S.C. §§ 158(a)(5), 159(a); see generally First Nat. Maint.
    Corp. v. NLRB, 452 U.S 666, 674–79 (1981). The Employers
    speculate that if they had refused to enforce Section 13.2, then
    the Board would have entertained contract modification
    charges from the marine clerk’s union. Even if that were true,
    which we need not decide, it does not change the Employers’
    statutory and contractual obligations to Local 26.
    “[A] contract cannot bind a nonparty.” EEOC v. Waffle
    House, Inc., 
    534 U.S. 279
    , 294 (2002). Local 26, the watchmen
    employees’ union, was not a party to the Clerks’ Agreement.
    Neither was there evidence that Local 26 had acted in a manner
    as would give the Employers reason to conclude that Local 26
    had agreed, albeit informally and not in writing as Article 21
    contemplated, to the use of Section 13.2 procedures where a
    non-watchman files a complaint against a covered watchman,
    nor any other evidence that the Agreement permitted this
    departure from Article 18 procedures. Local 26 is apparently
    the last holdout among unions with which Pacific contracts to
    use Section 13.2 procedures, most recently in negotiations for
    the 2014-2019 Watchmen’s Agreement. The Employers point
    to no conduct by Local 26 that provided a basis for them to
    conclude that the Agreement would permit using Section 13.2
    procedures against watchman Pleas.
    17
    In sum, this contractual defense, much like the Employers’
    others, ignores the plain text of the Watchmen’s Agreement,
    the parties’ bargaining history, and their negotiations for the
    2014-2019 contract where Local 26 again rejected the
    Employers’ proposal to import the special Section 13.2
    disciplinary procedure in the Clerks’ Agreement into the
    Watchmen’s Agreement. The remainder of the Employers’
    challenges to the contract-modification violation fail because
    the Board’s findings are supported by substantial evidence in
    the record considered as a whole.
    Our dissenting colleague changes the question before the
    court. To avoid the plain text of the Watchmen’s Agreement
    covering Pleas, the dissent defines the relevant question as
    whether the Employers had “a sound arguable basis for
    concluding that employee discipline may occur before or apart
    from filing an employer grievance under the Watchmen’s
    Agreement.” Dis. Op. 13; see also
    id. 2, 16.
    The answer
    provided distorts the standard adopted by the Board for the
    sound arguable basis exception, and it does not meaningfully
    engage with the Employers’ disciplinary action against Pleas
    nor with Article 18(H)’s exclusivity and exhaustion
    requirements, much less Article 18’s provisions on individual
    cases of employee discipline. Not only does Article 18(H)
    provide that the Article 18 procedures are the “exclusive
    remedy with respect to any dispute arising under the
    [Watchmen’s Agreement],”
    id. (emphasis added), but
    Article
    18(D) regarding employer complaints of employee discipline,
    provides that Employers “may implement the established
    procedures as outlined in Articles 18 and 19 of Agreement,”
    Article 18(D)(1). Article 18(D)(1) requires the Employers to
    participate in a good faith discussion with Local 26 prior to
    implementing the Article 18 procedures, namely referring a
    matter to the Joint Committee, Article 18(E), or filing a formal
    complaint, Article 18(D); there is no exception to Article
    18
    18(H)’s exclusivity and exhaustion requirements. To the
    extent our colleague interprets Article 18(H) to mean that the
    Pleas disciplinary incident did not “aris[e] under” the
    Watchmen’s Agreement, this interpretation also flounders on
    the plain text. And in responding to the dissent by pointing to
    the plain text’s statement of what Article 18(H)’s exclusivity
    entails, the court does not create a rationale for denying the
    petitions    other    than    the    Board’s     reliance   on
    Article 18.
    Authority involving a different context and different
    contract terms does not advance the dissent’s position. See Dis.
    Op. 10–11. For example, in Nolde Bros., Inc. v. Local No. 358,
    
    430 U.S. 243
    (1977), the Supreme Court considered whether
    an arbitration clause in a CBA that required the parties to
    arbitrate “any grievance” arising between the parties applied to
    a contractual dispute over severance pay that arose after the
    contract’s termination.
    Id. at 244–45, 248–49.
    Moreover, even
    applying the reasoning in Nolde Brothers to Article 18(H), the
    Court’s interpretation of “arising under” supports the Board’s
    conclusion that the Employers lacked a sound arguable basis
    for their disciplinary action, which was precluded by the plain
    text of the Watchmen’s Agreement.
    Nor does resolution of whether Pleas’ conduct violated the
    no-discrimination provision of Article 16 “hinge[] on the
    interpretation ultimately given” by the Arbitrator to the Section
    13.2 policy of the Clerks’ Agreement, Nolde 
    Bros., 430 U.S. at 249
    , because the present dispute does not cease to arise under
    the Watchmen’s Agreement simply because the Employers
    chose not to determine whether Pleas violated Article 16 of that
    Agreement using Article 18 procedures and instead chose to
    apply the different procedures and penalties in the Clerks’
    Agreement, enforcing Section 13.2 remedies in the Arbitrator’s
    order. The Employers did not challenge the Board’s internal
    19
    operating procedures using three-member panels, see Dis. Op.
    19, and consequently that issue is not properly before the court,
    see 29 U.S.C. § 160(e).
    B.
    An employer violates Sections 8(a)(5) and (1) “by
    unilaterally changing an existing term or condition of
    employment without first bargaining to impasse.” Regal
    Cinemas, Inc. v. NLRB, 
    317 F.3d 300
    , 309 & n.5 (D.C. Cir.
    2003). The General Counsel must show that “there is an
    employment practice concerning a mandatory bargaining
    subject, and that the employer has made a significant change
    thereto without bargaining.” Bath Iron 
    Works, 345 N.L.R.B. at 501
    (emphasis in original). Disciplinary procedures are a
    mandatory subject of bargaining. See, e.g., El Paso 
    Elec., 355 N.L.R.B. at 453
    .
    The Employers contend that the Board’s finding that there
    was a significant change to an established employment practice
    is not supported by substantial evidence. They assert that
    allegations of worker-versus-worker discrimination were not
    previously addressed in any consistent way and were often
    handled outside of Article 18’s process. But the record before
    the Board shows that the parties had consistently utilized the
    established Article 18 disciplinary procedure in the
    Watchmen’s Agreement to discipline bargaining unit
    employees and that this included the informal resolution of
    disputes prior to the issuance of formal employer complaints.
    See, e.g., Bill Carson testimony, ALJ Hr’g Tr. 465–66 (Apr.
    17, 2018); Letter of March 31, 2017, from Long Beach General
    Manager Bill Carson to Luisa Gratz, Local 26 President; Letter
    of April 27, 2017, from Long Beach to Pleas. Indeed, as noted,
    even in the present case Long Beach acknowledged that if Pleas
    were to be formally disciplined, it would be pursuant to the
    20
    Watchmen’s Agreement. Although there is no evidence of an
    established practice for handling inter-union employee
    complaints, the Employers acknowledge that a non-Local 26
    employee had never filed a harassment complaint against a
    watchman. Pet’rs’ Br. 53. Absent established disciplinary
    practices to resolve this type of dispute, the Employers’
    decision to enforce Section 13.2 against a covered watchman
    was a change in practice and itself a deviation from the status
    quo that supports the Board’s determination that there was a
    unilateral change without bargaining. See NLRB. v. Katz, 
    369 U.S. 736
    , 744–47 (1962); Wilkes-Barre Hosp. Co. v. NLRB,
    
    857 F.3d 364
    , 375–76 (D.C. Cir. 2017). Cf. E.I. Du Pont De
    Nemours & Co. v. NLRB, 
    682 F.3d 65
    , 67–68 (D.C. Cir. 2012).
    The Employers’ invocation of the contract coverage
    doctrine fares no better. The court has interpreted the “contract
    coverage” standard in unilateral-change cases to present the
    question whether a union has already “exercise[d] its right to
    bargain” by memorializing in a contract the employer’s right to
    act unilaterally, thereby removing the covered action from the
    range of further mandatory bargaining. NLRB v. U.S. Postal
    Serv., 
    8 F.3d 832
    , 836 (D.C. Cir. 1993) (quoting Local Union
    No. 
    47, 927 F.2d at 640
    ). The evidence does not show that
    Local 26 ever “surrendered the[] right to bargain over the . . .
    change[] through either waiver or contract.” Wilkes-Barre
    
    Hosp., 857 F.3d at 376
    (quoting S. Nuclear 
    Operating, 524 F.3d at 1357
    ).
    The Employers maintain that the Board’s ruling must be
    vacated because the Board applied a “clear and unmistakable
    waiver” standard and the Board recently ruled that the
    “contract coverage” doctrine is the appropriate mode of
    analysis, MV Transp., 
    368 NLRB No. 66
    , 
    2019 WL 4316958
    ,
    at *1. The Board noted that application of the “contract
    coverage” standard would not require a different result. Pac.
    21
    Mar. Ass’n, 
    367 NLRB No. 121
    , 
    2019 WL 1977314
    , at *6 n.21.
    Even so, the Employers maintain that the Board failed to
    explain, under the contract coverage doctrine, why procedures
    related to employee discipline in the Watchmen’s Agreement
    did not encompass the Employers’ decision to apply Section
    13.2 to Pleas. Yet after reviewing the text of the Watchmen’s
    Agreement, the parties’ bargaining history, and the parties’ past
    practice, and concluding that the Employers had no sound
    arguable basis for their interpretation of the Agreement, the
    Board also concluded that the Agreement did not cover the
    Employers’ disciplinary action.
    Id. at *5–6
    & n.21. Given the
    overlap between the sound arguable basis and contract
    coverage analysis, (as conceded by the Employers, see Oral
    Arg. Tape 6:55–8:17 (Jan. 22, 2020)), the Employers fail to
    demonstrate that the Board’s explanation was deficient.
    To conclude that a CBA covers the challenged unilateral
    conduct, the conduct must fall “within the compass or scope of
    contract language granting the employer the right to act
    unilaterally.” MV Transp., 
    368 NLRB No. 66
    , 
    2019 WL 4316958
    , at *17; see also Wilkes-Barre 
    Hosp., 857 F.3d at 377
    .
    In the Employers’ view, their conduct falls “within the
    compass” of the Watchmen’s Agreement even if the
    Agreement does not specifically authorize discipline pursuant
    to Section 13.2 because the Agreement grants an “unrestricted
    unilateral right to impose discipline for a number of broadly
    stated reasons” and “any dispute over the propriety of Pleas’s
    discipline falls ‘within the compass’ of the Watchmen’s
    Agreement.” Pet’rs’ Br. 59–60. As noted, Pleas was not
    disciplined for any of the exempted offenses in Article 18(C),
    and disciplinary disputes falling within the terms of Article 16
    of the Watchmen’s Agreement are governed by Article 18’s
    procedure, which is exclusive and does not encompass Section
    13.2. Given the text of the Watchmen’s Agreement and the
    Employers’ bargaining history with Local 26, their attempt to
    22
    stretch the Agreement to cover the Section 13.2 discipline is
    implausible at best. Although the contract coverage standard
    does not require that the parties’ Agreement “specifically
    mention” the disciplinary action at issue, see Wilkes-Barre
    
    Hosp., 857 F.3d at 377
    (quoting Enloe Med. Ctr. v. NLRB, 
    433 F.3d 834
    , 839 (D.C. Cir. 2005)), nor does it mean an employer
    can unilaterally change the terms and conditions of
    employment without bargaining because they fall within a
    broad subject area that the parties’ Agreement had addressed in
    other respects, cf.
    id. at 376–77.
    The Employers’ interpretation
    of the Watchmen’s Agreement would render its long-familiar
    and carefully bargained-for terms meaningless by achieving
    the modification of the Agreement that Local 26 had repeatedly
    rejected during bargaining with Pacific. This approach is
    contrary to the Employers’ statutory obligations under Sections
    8(a)(5) and (d) of the Act to adhere to the terms of the
    Agreement and effectively dismisses the Supreme Court’s
    reasoning on the importance of abiding by the parties’
    Agreement, see First Nat. Maint. 
    Corp., 452 U.S. at 674
    .
    In sum, assuming that both of the theories for violation can
    be applied, the court sustains the Board’s determinations that
    the Employers made both a midterm contract modification and
    a unilateral change to the terms and conditions of Pleas’
    employment. The Board could properly conclude, in view of
    the plain text of the Watchmen’s Agreement, that there was no
    “sound arguable basis” for the Employers to apply the Clerks’
    Agreement Section 13.2 procedures and enforce the
    Arbitrator’s order against Pleas, who was covered under the
    Watchmen’s Agreement. And, by so doing, the Employers
    unlawfully unilaterally changed the terms and conditions of
    Pleas’ employment. Accordingly, the court denies the petitions
    for review and grants the Board’s cross-applications for
    enforcement of its Order.
    RAO, Circuit Judge, concurring in part and dissenting in
    part: The National Labor Relations Board (“NLRB” or “the
    Board”) found the employers in this case violated federal law
    by committing two unfair labor practices: first, unlawfully
    modifying a collective bargaining agreement without union
    consent; and second, unilaterally imposing new terms and
    conditions of employment without providing the union notice
    and an opportunity to bargain. While the majority enforces both
    unfair labor practices, I would vacate the contract modification
    finding. The Board may find a contract modification only when
    an employer violates a specific contractual term that plainly
    bars the actions taken. Because the relevant collective
    bargaining agreement is silent or at least ambiguous as to the
    discipline imposed in this case, the employers had reasonable
    grounds for their disciplinary actions under the “sound
    arguable basis” standard. This well-established standard
    ensures that the Board does not overreach into ordinary labor
    contractual disputes that Congress placed firmly within the
    jurisdiction of the federal courts. Because the majority relaxes
    longstanding standards for contract modification, I respectfully
    dissent from Part II.A of the court’s opinion.
    I.
    The majority carefully sets out the relevant facts, Maj. Op.
    2–7, but I would frame this contractual dispute in a somewhat
    different way. The Long Beach Container Terminal and the
    Pacific Maritime Association (“the Employers”) entered into
    a collective bargaining agreement known as the Watchmen’s
    Agreement with ILWU, Warehouse, Processing and
    Distribution Workers’ Union, Local 26 (“the Union”). The
    Union represents watchmen at the Employers’ port facilities.
    Demetrius Pleas was a member of the Union and thus subject
    to the Watchmen’s Agreement. Marine clerks at the port
    facilities are represented by a different union operating under
    a different contract, the Pacific Coast Longshore and Clerks’
    Agreement (“Clerks’ Agreement”). When Pleas made racially
    2
    insensitive comments in the workplace, a marine clerk filed
    a complaint under Section 13.2 of the Clerks’ Agreement,
    which sends discrimination complaints to an arbitrator to
    resolve factual disputes and recommend appropriate discipline.
    The Employers allowed the clerk’s complaint against Pleas to
    proceed under Section 13.2 and imposed the arbitrator’s
    recommended discipline. Both the Board and the majority
    emphasize that the Employers used the wrong mechanism
    when disciplining Pleas because they should have filed
    a grievance under Article 18 of the Watchmen’s Agreement
    rather than use the Section 13.2 process. Pac. Mar. Ass’n, 
    367 NLRB No. 121
    , at *5–6 (May 2, 2019); see Maj. Op. 9–19.
    The distinction between Section 13.2 of the Clerks’
    Agreement and Article 18 of the Watchmen’s Agreement,
    however, is a red herring. The contract modification charge
    does not turn on whether the Employers disciplined Pleas
    pursuant to the Section 13.2 process. Rather, the dispositive
    issue is whether the Watchmen’s Agreement allows the
    Employers to impose discipline at their discretion or instead
    requires the Employers to discipline Union members
    exclusively through an Article 18 grievance. Thus, my analysis
    focuses on whether the Employers justified disciplining Pleas
    under a reasonable interpretation of the Watchmen’s
    Agreement—a burden they readily carried here—and whether
    the Board respected limitations on its jurisdiction by
    adjudicating this case under the appropriate legal standard.
    Understanding the Board’s limited authority over
    contractual matters requires recollecting the distinction
    between unfair labor practices under the National Labor
    Relations Act of 1935 (“NLRA”) and breaches of contract
    under the Labor Management Relations Act of 1947
    (“LMRA”), a distinction the majority overlooks. The NLRA
    creates public rights related to collective bargaining and
    3
    empowers the Board to adjudicate unfair labor practices
    infringing those rights. Section 8(a)(5) and (1) of the NLRA
    make it unlawful for an employer to “refuse to bargain” with
    employee representatives on wages, hours, and other
    mandatory subjects of bargaining. 29 U.S.C. § 158(a)(5), (1).
    Section 8(d) protects the integrity of the collective bargaining
    process by prohibiting parties from “terminat[ing] or
    modify[ing]” provisions “contained in” a collectively
    bargained agreement.
    Id. § 158(d), (d)(4).
    The Board’s
    authority over matters of contract extends only as far as
    adjudicating unfair labor practices. Traditional contractual
    disputes, by contrast, are reserved for the federal courts under
    Section 301 of the LMRA, which recognizes that collective
    bargaining agreements are voluntary contracts between
    employers and unions giving rise to private rights when
    breached. To vindicate contractual rights, the LMRA grants
    district courts broad jurisdiction over “[s]uits for violation of
    contracts between an employer and a labor organization.” 29
    U.S.C. § 185(a); see Dist. No. 1 v. Liberty Mar. Corp., 
    933 F.3d 751
    , 756–58 (D.C. Cir. 2019).
    The jurisdictional division between the NLRA and the
    LMRA means the Board interprets contracts only “so far as [is]
    necessary” to determine whether an unfair labor practice
    occurred. Honeywell Int’l, Inc. v. NLRB, 
    253 F.3d 119
    , 124
    (D.C. Cir. 2001) (quoting NLRB v. C&C Plywood Corp., 
    385 U.S. 421
    , 428 (1967)). “But the federal courts, not the Board,
    are legislatively empowered to be the primary interpreters of
    contracts.”
    Id. (citing Litton Fin.
    Printing Div. v. NLRB, 
    501 U.S. 190
    , 202–03 (1991)). Under prevailing standards for
    contract-related unfair labor practices and associated defenses,
    the Board performs a “limited review” of a labor contract’s
    plain language to determine whether to assert jurisdiction. MV
    Transp., Inc., 
    368 NLRB No. 66
    , at *17 (Sept. 10, 2019).
    Resolving contractual ambiguity by reaching beyond the plain
    4
    meaning, however, is a task reserved for the courts. As the
    agency freely admits, “the Board is not an expert in contract
    interpretation, nor was it intended to be.”
    Id. at *9
    (cleaned up).
    When contractual obligations are in dispute, “[t]he Board is not
    the proper forum for parties seeking an interpretation of their
    collective-bargaining agreement.” Vickers, Inc., 
    153 N.L.R.B. 561
    , 570 (1965). That much flows from the bargaining
    structure of the NLRA, which leaves employers and unions free
    to set the terms and conditions of employment by mutual
    consent rather than administrative fiat. Orders of the Board are
    “ineffective to determine any private rights of the employees
    and leave[] them free to assert such legal rights as they may
    have acquired under their contracts.” Nat’l Licorice Co. v.
    NLRB, 
    309 U.S. 350
    , 366 (1940); cf. Stern v. Marshall, 
    564 U.S. 462
    , 484 (2011) (“[I]n general, Congress may not
    ‘withdraw from judicial cognizance any matter which, from its
    nature, is the subject of a suit at the common law, or in equity,
    or admiralty.’”) (quoting Murray’s Lessee v. Hoboken Land &
    Improvement Co., 59 U.S. (18 How.) 272, 284 (1856)).
    Jurisdictional considerations thus operate in the
    background of the Board’s adjudication of contract
    modification charges under Sections 8(a)(5) and (d). Judicial
    review of such cases ensures the Board respects limits on its
    authority and does not decide breach of contract claims that
    Congress assigned to the courts. Accordingly, we review the
    Board’s contract interpretation de novo while according
    substantial evidence deference to the agency’s findings of fact.

    As the Board has explained on multiple occasions, contract
    modification and unilateral change unfair labor practices “are
    fundamentally different in terms of principle, possible
    defenses, and remedy.” ADT, LLC,

    Bath Iron Works Corp., 
    345 N.L.R.B. 499
    , 501 (2005). In this
    case, the Board found that the Employers both unilaterally
    changed established practice and modified the Watchmen’s
    Agreement by imposing terms from Section 13.2 of the Clerks’
    Agreement. Pac. Mar., 
    367 NLRB No. 121
    , at *5–6. In doing
    so, the Board contradicted precedents that foreclose finding
    both unilateral change and contract modification based on the
    same underlying employer conduct.1 Because the Employers
    1
    Although our court has yet to definitively address the issue, the
    Board’s precedents have long treated contract modification and
    unilateral change as mutually exclusive. Contract modification
    charges “require greater proof” because their remedy—specific
    performance of the contract’s terms—is more severe than that
    assessed for the “lesser allegation” of unilateral change. ABF Freight
    Sys., Inc., 
    369 NLRB No. 107
    , at *4 & n.8 (June 19, 2020) (citing
    Bath Iron 
    Works, 345 N.L.R.B. at 502
    –03). In rare situations, the Board
    has found both violations when an employer imposed multiple rules
    at the same time, some of which modified an existing contract and
    some of which altered established practice. See, e.g., Comau, Inc.,
    
    364 NLRB No. 48
    , at *4–6 (July 14, 2016). Since deciding this case,
    the Board has reaffirmed that the findings are mutually exclusive:
    “Unlike an employer that unlawfully modifies a contract, an
    employer that implements an unlawful unilateral change only needs
    to restore the status quo ante until the parties reach an impasse in
    bargaining. Because the remedies are mutually exclusive, an
    allegedly unlawful employer decision cannot be both a unilateral
    6
    failed to challenge the joint nature of the findings, however, we
    cannot vacate the Board’s order on this basis. 29 U.S.C.
    § 160(e); see Maj. Op. 8.
    On these facts, I join the majority in enforcing the Board’s
    unilateral change finding because the Employers imposed new
    terms and conditions of employment without giving the Union
    notice and an opportunity to bargain. Pac. Mar., 367 NLRB
    No. 121, at *6; see Maj. Op. 19–22. Unilateral changes to prior
    practices violate Sections 8(a)(5) and (1) by circumventing the
    Section 8(d) procedural protections meant to promote
    collective bargaining. NLRB v. Katz, 
    369 U.S. 736
    , 743 (1962).
    To prove a unilateral change, the Board must show (1) “an
    established past practice” and (2) “‘a material, substantial, and
    significant change’” to that practice without bargaining. ABF
    Freight Sys., Inc., 
    369 NLRB No. 107
    , at *2 (June 19, 2020)
    (quoting MV Transp., 
    368 NLRB No. 66
    , at *4). Substantial
    evidence supports the Board’s view that the Employers had
    established past practices of investigating discrimination
    allegations against watchmen informally and imposing less
    severe penalties than those levied against Pleas. By
    participating in and adopting the results of procedures from
    Section 13.2 of the Clerks’ Agreement, the Employers made
    material changes to employee discipline, an employment term
    recognized as a mandatory subject of bargaining. See El Paso
    Elec. Co., 
    355 N.L.R.B. 428
    , 453 (2010).
    Yet these same facts do not support a contract modification
    violation, which turns on matters of contract interpretation for
    which the Board has considerably less prerogative and enjoys
    change and a contract modification.” ADT, 
    369 NLRB No. 31
    , at *3
    (citing Bath Iron 
    Works, 345 N.L.R.B. at 503
    ). While the NLRB’s
    general counsel may allege both theories in the alternative, the Board
    will not find both violations simultaneously.
    Id. 7
    no judicial deference. Contract modification is an unfair labor
    practice under Sections 8(a)(5) and (d) because failing to
    adhere to agreed-upon terms undermines collective bargaining
    and a union’s role as the employees’ chosen representative. To
    find contract modification, the Board must (1) identify
    “a specific term ‘contained in’ the contract” to which a party
    failed to adhere without the consent of the counterparty, United
    Auto. Workers v. NLRB, 
    765 F.2d 175
    , 179 (D.C. Cir. 1985)
    (quoting 29 U.S.C. § 158(d)(4)), and (2) assess the four corners
    of the agreement to determine whether the charged party has
    a “sound arguable basis” for interpreting the contract to support
    its actions, Bath Iron 
    Works, 345 N.L.R.B. at 502
    . Under the
    “sound arguable basis” standard, an alleged breach of contract
    is not an unfair labor practice if the party acted under
    a “reasonable” interpretation of the contract. MV Transp., 
    368 NLRB No. 66
    , at *28. “[W]hen ‘an employer has a sound
    arguable basis for ascribing a particular meaning to his contract
    and his action is in accordance with the terms of the contract as
    he construes it,’ the Board will not enter the dispute to serve
    the function of arbitrator in determining which party’s
    interpretation is correct.” NCR Corp., 
    271 N.L.R.B. 1212
    , 1213
    (1984) (quoting 
    Vickers, 153 N.L.R.B. at 570
    ). In other words,
    only clear violations of an unambiguous term rise to the level
    of an unlawful contract modification.
    In finding contract modification on these facts, the Board
    departed from longstanding precedent in three ways. First, the
    Board failed to identify a specific contract provision “contained
    in” the Watchmen’s Agreement that the Employers modified.
    Second, the Board misapplied the “sound arguable basis”
    standard by rejecting the Employers’ reasonable interpretation
    of the Watchmen’s Agreement as allowing employee discipline
    outside the Article 18 grievance process. Third, by relying on
    extrinsic evidence of bargaining history, the Board
    transgressed the limitations on its contract interpretation
    8
    authority. In my view, any one of these errors requires vacating
    the contract modification finding. Taken together, they
    represent a troubling departure from applicable standards and
    undermine the clarity and predictability of federal labor law.
    A.
    To determine whether the Employers unlawfully modified
    the contract, the Board was required first to identify a specific
    term “contained in” in the Watchmen’s Agreement that the
    Employers ignored without the Union’s consent. United Auto.
    
    Workers, 765 F.2d at 179
    ; see also St. Vincent Hosp., 
    320 N.L.R.B. 42
    , 42 (1995); Milwaukee Spring Div., 
    268 N.L.R.B. 601
    ,
    602 (1984). The Board concluded the Employers modified
    Articles 18(D) and (H) by disciplining Pleas after arbitration
    under Section 13.2 of the Clerks’ Agreement rather than filing
    an employer grievance under Article 18 of the Watchmen’s
    Agreement. Pac. Mar., 
    367 NLRB No. 121
    , at *5–6. Although
    employee arbitration under Section 13.2 was a departure from
    prior practice and thus an unlawful unilateral change, this does
    not necessarily mean the Employers modified Article 18 when
    they adopted the results of arbitration. Instead, the ultimate
    question is whether the Watchmen’s Agreement requires the
    Employers to discipline Pleas exclusively through Article 18’s
    “Grievance Machinery.” Watchmen’s Agreement at 33
    (“W.A.”). For the following reasons, the Watchmen’s
    Agreement provisions identified by the Board do not require
    the Employers to discipline employees exclusively through an
    employer grievance under Article 18.
    As an initial matter, “grievance” is a term of art in the
    collective bargaining context that means more than
    a “complaint” or “dispute.” As the Supreme Court has
    explained, “[t]he processing of disputes through the grievance
    machinery is actually a vehicle by which meaning and content
    9
    are given to the collective bargaining agreement.” United
    Steelworkers of Am. v. Warrior & Gulf Nav. Co., 
    363 U.S. 574
    ,
    581 (1960). The Watchmen’s Agreement grievance machinery
    is a specific type of complaint process that covers some, but
    not all, disputes arising between employees and the Employers.
    Article 18(D) requires the Employers to attempt informal
    resolution with affected parties before submitting
    a “grievance” to the joint Labor Relations Committee.2 If the
    Committee is unable to negotiate a resolution, the matter may
    proceed to arbitration between the Employers and the Union.
    W.A. at 33–34; see also Art. 18(E)–(G), W.A. at 34–35.
    Nothing in Article 18(D) requires or suggests that the
    2
    Article 18(D) reads, in relevant part:
    Prior to a complaint being filed by the Employer or the
    Union, the following procedures shall apply:
    (1.) (A.) The Employer shall notify and discuss the alleged
    incident with the individuals involved and president and/or
    a steward of [the Union] and attempt to resolve the matter.
    Whatever evidence the parties have or have relied upon
    relating to the discharge and/or grievance shall be provided
    to the Union at the time of request. … Following a good faith
    discussion with the Union, … the Employers may implement
    the established procedures as outlined in Articles 18 and 19
    of the Agreement.
    (B.) The Union shall notify and discuss the alleged incident
    with management and attempt to resolve the matter. …
    Following a good faith discussion with the Employer, … the
    Union may implement the established procedures as outlined
    in Article[s] 18 and 19 of the Agreement.
    (2.) In cases of discipline and/or discharge, the Employer
    shall identify, specifically, and describe in detail the
    violation committed by the watchman. The Employer shall
    specify the company procedure and/or Contract provision
    violated.
    10
    Employers must file a contractual grievance before
    investigating employee misconduct or imposing discipline.
    Similarly, Article 18(H) speaks to the scope of the
    grievance procedure but does not require prior Labor Relations
    Committee approval of employee discipline: “This grievance
    machinery shall be the exclusive remedy with respect to any
    dispute arising under the Collective-Bargaining Agreement
    and no other remedies shall be used by the Union, the
    Employer, or any covered employee until the grievance
    procedures have been exhausted.” W.A. at 35. Article 18(H)
    says nothing about employee discipline. Yet the Board and the
    majority would insert new language into the Watchmen’s
    Agreement by reading Article 18(H) to “expressly limit[] the
    Employers’ ability to discipline employees ‘with respect to any
    dispute arising under the [Agreement].’” Maj. Op. 11
    (emphasis added). There is simply no textual basis for claiming
    that Article 18(H) makes any provision, express or otherwise,
    regarding the discipline of employees. Accord Pac. Mar., 
    367 NLRB No. 121
    , at *12 (Kaplan dissenting).
    The Watchmen’s Agreement subjects only those disputes
    “arising under” its terms exclusively to the Article 18 grievance
    process. Grievances “aris[e] under” a contract provision when
    “the resolution of that claim hinges on the interpretation
    ultimately given the contract clause.” Nolde Bros., Inc. v. Local
    No. 358, 
    430 U.S. 243
    , 249 (1977). Despite containing detailed
    rules on many aspects of the employment relationship, the
    Agreement is generally silent on matters of discipline. The
    Employers’ decision to discipline in this case does not “arise
    under” the Agreement because no term speaks to Pleas’s
    conduct or the resulting consequences. Grievance procedures
    like those in Article 18 cannot be read expansively to cover
    matters outside the contract without undermining the freedom
    of contract policies embedded in federal labor law. Cf. Dep’t of
    11
    Navy v. FLRA, 
    962 F.2d 48
    , 57 (D.C. Cir. 1992) (“Because of
    the fundamental policy of freedom of contract, the parties are
    generally free to agree to whatever specific rules they like, and
    in most circumstances it is beyond the competence of the …
    National Labor Relations Board or the courts to interfere with
    the parties’ choice.”). Without any indication that the parties
    intended to do so, we have no basis for assuming a contractual
    grievance process covers individual cases of employee
    discipline.3
    In reaching a contrary reading of Articles 18(D) and (H),
    the Board stated only that “article 18’s plain language
    establishes that the parties intended to prohibit all other
    mechanisms—including, a fortiori, one set forth in a different
    contract covering a different bargaining unit—for addressing
    alleged watchman misconduct.” Pac. Mar., 
    367 NLRB No. 121
    , at *5. The majority now adopts this finding by relying on
    an argument the Board did not: that this dispute “arose under”
    Article 16 of the Watchmen’s Agreement, which “broadly
    prohibits discrimination against ‘any person’ on the basis of
    ‘race, color, national origin, [and] religious or political
    beliefs.’” Maj. Op. 11, 18–19. The Board, however, relied
    exclusively on its reading of Article 18 to find an unlawful
    contract modification. See Pac. Mar., 
    367 NLRB No. 121
    , at
    3
    The grievance provision of the Clerks’ Agreement, by contrast,
    explicitly specifies that a joint labor relations committee shall
    “investigate and adjudicate any complaint against any clerk whose
    conduct on the job … causes disruption of normal harmony in the
    relationship of the parties hereto or the frustration and/or violation of
    the provisions of the working or dispatching rules or of this
    Agreement.” Clerks’ Agreement § 17.125, at 59. The contrast
    between this language and Article 18(H) demonstrates the
    Employers and the Union had alternative language readily available
    but instead left discipline outside the scope of matters subject
    exclusively to the grievance process in the Watchmen’s Agreement.
    12
    *5–6.4 We cannot sustain an agency’s decision on a different
    basis than the one relied upon below. See SEC v. Chenery
    Corp., 
    332 U.S. 194
    , 196–97 (1947); Point Park Univ. v.
    NLRB, 
    457 F.3d 42
    , 50 (D.C. Cir. 2006) (“Nor can our Court
    fill in critical gaps in the Board’s reasoning. We can only look
    to the Board’s stated rationale.”).
    Because the Board cannot identify a specific term in the
    Watchmen’s Agreement that subjects employee discipline to
    the grievance procedure, the Employers did not modify specific
    terms and conditions contained in the Agreement. The Board
    failed to establish an unlawful contract modification.
    B.
    Even if Article 18 addressed the question of employee
    discipline, the Board cannot sustain a contract modification
    charge if the Employers had a “sound arguable basis” for
    interpreting the Watchmen’s Agreement to permit their
    disciplinary actions. Reading the Watchmen’s Agreement as
    a whole, the Employers clearly had a “sound arguable basis”
    for their conduct because the Agreement was at least
    ambiguous with respect to employee discipline outside the
    contractual grievance procedures of Article 18.
    As discussed above, nothing in the plain terms of Article
    18 requires discipline to proceed through an employer
    grievance. Moreover, despite relying heavily on Article 18(D),
    the Board and the majority ignore clear references to employee
    4
    The Board referred to Article 16 to reject an argument by one of the
    Employers that the provision, if applicable, would allow the
    Employers to investigate and discipline based on such complaints.
    See Pac. Mar., 
    367 NLRB No. 121
    , at *6 n.20. But the Board never
    found the Employers filed a complaint under Article 16 or that the
    dispute turned on interpreting this provision.
    13
    discipline arising outside the grievance machinery. For
    instance, Article 18(D)(1) presupposes that a discharge and
    a grievance are distinct employer actions: “Whatever evidence
    the parties have or have relied upon relating to the discharge
    and/or grievance shall be provided to the Union at the time of
    request.” W.A. at 33–34 (emphasis added); see Encino
    Motorcars, LLC v. Navarro, 
    138 S. Ct. 1134
    , 1141 (2018)
    (“‘[O]r’ is ‘almost always disjunctive.’”) (citation omitted).
    Moreover, Article 18(D) uses the past tense when referring to
    employee discipline, suggesting review of discipline under the
    grievance process could occur post hoc. See W.A. at 33–34.
    These provisions at a minimum support a sound arguable basis
    for concluding that employee discipline may occur before or
    apart from filing an employer grievance under the Watchmen’s
    Agreement.
    Next, the Board and the majority fail to consider the
    broader structure of the Labor Relations Committee as
    reflected in Articles 18(A) and (J). Article 18(A) establishes
    the Committee “to resolve grievances, secure conformance to
    the terms of the Agreement, maintain current employee
    registration rosters, maintain dispatch procedures, and
    generally administer the Agreement.” W.A. at 33. None of
    these roles for the Committee include employee discipline, and
    the term “grievance[]” is not naturally read to include
    allegations of employee misconduct. Supra at 8–10. Article
    18(J) includes an extensive list of topics the Committee must
    discuss on at least a monthly basis. W.A. at 35.5 Yet despite
    5
    Article 18(J) reads:
    There shall be designated monthly [Labor Relations
    Committee] meetings for the following purposes:
    (1.) Two (2) regularly scheduled meetings each month
    exclusively for general LRC issues
    14
    containing significant detail, the list does not include matters
    of employee discipline. If the Committee were intended as the
    sole adjudicator of misconduct allegations for hundreds of
    employees at a large shipping terminal, one would expect this
    responsibility to be explicit.
    Finally, the Employers offer a persuasive interpretation of
    Article 18(C), which includes the Agreement’s only reference
    to disciplinary rules.6 This provision instructs the Labor
    Relations Committee to “establish rules and regulations
    governing the conduct of watchmen as well as penalties for the
    breach of these rules and regulations,” and provides further that
    “nothing herein shall restrict the Employer’s existing right to
    discipline or discharge” for five enumerated offenses not
    implicated in this case. W.A. at 33. According to the
    (2.) One (1) meeting exclusively for Registered Watchmens’
    complaints (non-dispatch issues)
    (3.) One (1) meeting exclusively for Dispatch Violations
    (4.) One (1) meeting exclusively for Emergency watchmen
    complaints
    (5.) One (1) Dispatch Committee meeting exclusively for
    Time Books and Emergency Watchmen Dispatch Audit
    (6.) One (1) meeting exclusively to audit Registered guards
    Dispatch Records and Reports
    (7.) One (1) meeting exclusively for Watchmen Safety.
    6
    Article 18(C) reads:
    The Labor Relations Committee shall establish rules and
    regulations governing the conduct of watchmen as well as
    penalties for the breach of these rules and regulations.
    However, nothing herein shall restrict the Employer’s
    existing right to discipline or discharge men for intoxication,
    pilferage, assault, incompetency, or failure to perform work
    as directed, but any man who considers that he has been
    improperly disciplined or discharged may appeal to the
    Labor Relations Committee.
    15
    Employers, Article 18(C)’s reference to an “existing right”
    means they retain the right to discipline for an offense unless
    the Committee issues rules and penalties applicable to that
    offense. The five enumerated offenses represent carve-outs for
    which the Committee cannot preempt the Employers’
    discretion. Read together, “a reasonable interpretation is that
    [Article 18(C)] is limited to granting the [Committee] the
    power to make disciplinary rules, so long as those rules do not
    restrict the employers’ right to discipline for the five
    enumerated offenses, but does not limit the Employer’s ability
    to discipline employees in the absence of any controlling
    [Committee] rule.” Pac. Mar., 
    367 NLRB No. 121
    , at *12
    (Kaplan dissenting). The majority says this interpretation
    renders the enumeration superfluous, Maj. Op. 12, but the
    Employers’ interpretation of Article 18(C) preserves a role for
    the grievance process to resolve complaints by the Union and
    the Employers, to channel disputes into binding arbitration, and
    to allow grievances to be filed after discipline if its imposition
    conflicts with the Agreement.
    The majority’s “sound arguable basis” analysis does not
    square with precedent. Rather than engage de novo with the
    plain meaning of the contract, the majority seeks to squeeze its
    interpretation into substantial evidence deference whenever
    possible. See Maj. Op. 13–16. Yet disputed evidence of past
    practice and bargaining history cannot supplant plain meaning,
    which, as discussed further below, is the lodestar of the sound
    arguable basis analysis. At most, the majority demonstrates that
    Article 18 may be interpreted to cover individual cases of
    employee discipline. But one plausible interpretation does not
    foreclose the Employers’ interpretation as fundamentally
    unsound.
    To defeat this contract modification charge, the Employers
    needed only a “sound arguable basis” to argue the Watchmen’s
    16
    Agreement allowed disciplining Pleas for racial harassment
    without filing an Article 18 grievance. Because the Agreement
    is at a minimum ambiguous on employee discipline outside the
    contractual grievance procedure, the Employers had a “sound
    arguable basis” for their disciplinary actions.
    C.
    The Board further erred by supporting its contract
    modification finding with extrinsic evidence that the Union
    rejected terms like those in Section 13.2 of the Clerks’
    Agreement and that the parties had not previously applied such
    procedures to discrimination allegations. The Board concluded
    that “the parties’ past practice and bargaining history” meant
    that the Employers “could not have mistaken or misunderstood
    [the Union’s] intent that no such [Section 13.2] procedure be
    applicable to watchmen.” Pac. Mar., 
    367 NLRB No. 121
    , at
    *5–6, *16. Under the “sound arguable basis” test, however, the
    Board’s authority to interpret contracts ends where ambiguity
    begins. Rather than dismiss the charge in the face of ambiguity,
    the Board reached beyond the four corners of the Watchmen’s
    Agreement by looking to the evidence it used to find
    a unilateral change violation. Yet as noted earlier, the contract
    modification analysis does not turn on whether the Employers
    applied Section 13.2 to Pleas, or whether the Union would have
    consented to amending Article 18 to include such procedures.
    Rather, the issue is whether the Employers had a “sound
    arguable basis” for disciplining Pleas without filing a grievance
    under the Watchmen’s Agreement. Relying on extrinsic
    evidence caused the Board’s decision to run crosswise with
    longstanding precedent.
    To begin with, the Board’s use of extrinsic evidence to
    rebut the Employers’ otherwise “sound arguable basis” rests on
    a misreading of prior cases. For example, the Board cites
    17
    Knollwood Country Club, 
    365 NLRB No. 22
    (Mar. 8, 2017),
    for the proposition that plain meaning and extrinsic evidence
    stand on equal footing when interpreting a contract. In
    Knollwood, however, the Board rejected an employer’s
    interpretation as unreasonable because the employer failed to
    read the contract as a whole and merely noted that extrinsic
    evidence “also” was consistent with the plain meaning of the
    contract.
    Id. at *1
    & n.8. This holding is consistent with
    ordinary principles of contract interpretation embracing the
    plain meaning approach. Moreover, Knollwood relied in
    relevant part on Mining Specialists, Inc., 
    314 N.L.R.B. 268
    , 268–
    69 (1994), a unilateral change case emphasizing that
    “contractual language … is always paramount.” Neither the
    Board nor the majority cite to a single case in which extrinsic
    evidence supported a finding of contract modification when the
    provision in question was ambiguous. In fact, both the agency’s
    precedents and the law of this circuit are clear that plain
    meaning governs when adjudicating unfair labor practices
    arising from contract.7 The Board’s limited statutory authority
    7
    See, e.g., Metalcraft of Mayville, Inc., 
    367 NLRB No. 116
    , at *4–5
    (Apr. 17, 2019) (dismissing charge where employer had
    a “colorable” argument that “conforming to applicable law”
    provision allowed it to stop deducting union dues pursuant to state
    law); MV Transp., 
    368 NLRB No. 66
    , at *28–34 (dismissing several
    charges where employer had a “sound arguable basis” for
    interpreting contract to allow new company policies); see also Am.
    Fed’n of Gov’t Emps. v. FLRA, 
    470 F.3d 375
    , 381 (D.C. Cir. 2006)
    (“Interpretation of a contract, like statutory and treaty interpretation,
    must begin with the plain meaning of the language.”). Evidence of
    prior practice and bargaining history, if mentioned at all, are cited
    only to note its consistency with plain meaning. See, e.g., ADT, 
    369 NLRB No. 31
    , at *5 & n.10 (concluding plain language required
    dismissing modification charge and then noting the parties’ past
    practice “further supports” the interpretation offered by the
    employer); Comau, 
    364 NLRB No. 48
    , at *5 & n.16 (in the absence
    of an applicable contract provision, prior practice demonstrated the
    18
    over contract disputes necessarily means it cannot use extrinsic
    evidence to refute plain meaning or resolve ambiguity, which
    is a role reserved for the courts.
    Perhaps the fundamental problem of the Board’s approach
    here is that it sought to revise the contract modification
    standard sub silentio. By deploying extrinsic evidence in
    a “sound arguable basis” inquiry, the Board failed to adhere to
    governing law setting out distinct evidentiary standards for
    contract modification and unilateral change. For example, in
    Bath Iron Works, the Board distinguished between contract
    modification and unilateral change and rejected arguments to
    apply the same standard to both charges. 
    See 345 N.L.R.B. at 501
    –02. Instead, the Board reaffirmed that the “sound arguable
    basis” test governs contract modification charges—a policy the
    Board continues to follow. See MV Transp., 
    368 NLRB No. 66
    ,
    at *13–17, *28 (emphasizing the Board’s limited authority to
    interpret contracts and declining to go beyond plain meaning
    when adjudicating unfair labor practices). Here, rather than
    assess the Employers’ “sound arguable basis” against the plain
    meaning of the Agreement, the Board held the Employers to
    a different standard by faulting them for not proving the Union
    would have accepted procedures like those in Section 13.2 of
    the Clerks’ Agreement.8
    contract applied to employees in question); Hosp. San Carlos, Inc.,
    
    355 N.L.R.B. 153
    , 153 & n.5 (2010) (concluding plain meaning
    foreclosed employer’s interpretation before observing that testimony
    regarding the parties’ intent also supported the conclusion).
    8
    To determine whether an employer unilaterally changed an
    established prior practice, the Board often looks to evidence of
    conduct and bargaining history—typically a mix of testimony and
    non-contractual written records. See, e.g., ABF Freight, 369 NLRB
    No. 107, at *2–3 (discussing evidence of employer’s past actions).
    Similarly, extrinsic evidence is relevant when an employer raises
    19
    This intermingling of legal frameworks for contract
    modification and unilateral change, however, has never been
    adopted by the Board as a whole and has been previously
    advanced only in dissenting opinions.9 Yet in this case, two
    members of a three-member panel conflated the evidentiary
    standard for contract modification with those for unilateral
    change and waiver. Unlike many multi-member agencies, the
    NLRB decides cases by delegating to three-member panels as
    a matter of course. See 29 U.S.C. § 153(b); NLRB, Guide to
    Board Procedures § 3.8(a) (Apr. 2017). As a consequence of
    this practice, a position held by a two-member minority of the
    five-member Board may prevail on a panel in a manner
    inconsistent with the Board’s governing precedents.10
    a waiver defense, which requires showing the union clearly and
    unmistakably waived its statutory right to bargain on the contested
    issue. See, e.g., Provena Hosps., 
    350 N.L.R.B. 808
    , 811 (2007).
    9
    Over the years, a persistent minority of the Board has questioned
    whether Bath Iron Works was wrongly decided and advocated for
    limiting the “sound arguable basis” standard or imposing a different
    standard that falls within the scope of the Board’s substantial
    evidence deference for factfinding. See, e.g., Metalcraft, 367 NLRB
    No. 116, at *15 (McFerran dissenting); MV Transp., 
    368 NLRB No. 66
    , at *41 (McFerran concurring in part and dissenting in part);
    Knollwood, 
    365 NLRB No. 22
    , at *1 n.5 (separate footnote by Pearce
    and McFerran); Comau, 
    364 NLRB No. 48
    , at *4 n.14 (separate
    footnote by Pearce and Hirozawa); Bath Iron 
    Works, 345 N.L.R.B. at 504
    (Liebman dissenting); see also Pac. Mar., 
    367 NLRB No. 121
    ,
    at *5 n.15 (separate footnote by McFerran) (reserving the question
    of whether Bath Iron Works was wrongly decided).
    10
    The question is not whether the procedure is permissible under the
    NLRA, or whether the Employers challenged its use in this case. Cf.
    Maj. Op. 18–19. Rather, the question is whether this panel of the
    Board followed the agency’s announced standards. Given the
    unexplained break with precedent evident in this case, I would
    answer that question in the negative.
    20
    Although the NLRA authorizes decisions by delegated panels,
    those panels must follow the Board’s announced standards in
    order to satisfy the reasoned decisionmaking requirement
    applicable to all administrative action. See Allentown Mack
    Sales & Serv., Inc. v. NLRB, 
    522 U.S. 359
    , 374 (1998). As
    a reviewing court, we must ensure the Board adheres to its
    announced standards, not the preferred interpretations of
    individual members. See Pub. Citizen, Inc. v. FERC, 
    839 F.3d 1165
    , 1169–70 (D.C. Cir. 2016) (applying the “almost
    universally accepted common-law rule” that “only a majority
    of a collective body is empowered to act for the body”)
    (cleaned up).
    The majority endorses the Board’s use of extrinsic
    evidence by taking a myopic view of governing law. When
    reviewing an adjudicatory standard, we must examine its
    application in prior cases and then determine whether the
    instant case is a faithful application of existing law. See Circus
    
    Circus, 961 F.3d at 476
    . Instead, the majority relies on
    a selective reading of the Board’s decision in Knollwood, see
    Maj. Op. 14, and fails to engage with cases like Bath Iron
    Works and MV Transportation that set out a clear plain
    meaning requirement. It is a fundamental principle of
    administrative law that prior departures from announced
    standards do not excuse an agency’s duty to acknowledge and
    justify a change in policy. “It is hard to imagine a more violent
    breach of that requirement than applying a rule of primary
    conduct or a standard of proof which is in fact different from
    the rule or standard formally announced. And the consistent
    repetition of that breach can hardly mend it.” Allentown 
    Mack, 522 U.S. at 374
    ; see, e.g., ABM Onsite Servs.-West, Inc. v.
    NLRB, 
    849 F.3d 1137
    , 1144–46 (D.C. Cir. 2017) (vacating
    order when the Board improperly applied the applicable
    standard over the course of four years). Without a reasoned
    revision by the Board of the “sound arguable basis” standard,
    21
    this court must reject individual decisions departing from those
    standards. The Board in this case was wrong to dislodge the
    employer’s reasonable interpretation using extrinsic evidence.
    *   *    *
    Contract modifications are breaches of contract that rise to
    the level of offending public rights by undermining the
    collective bargaining process. The “sound arguable basis”
    standard provides a means of separating unfair labor practices
    from contractual disputes reserved for the courts. See
    
    Honeywell, 253 F.3d at 123
    –25; Int’l Union, United Mine
    Workers of Am. v. NLRB, 
    257 F.2d 211
    , 215 (D.C. Cir. 1958).
    By finding a contract modification in these circumstances, the
    Board departed from precedent in an arbitrary and capricious
    manner and exceeded its limited jurisdiction over contract
    disputes. I therefore respectfully dissent from enforcing the
    Board’s contract modification finding.
