    Before: GARLAND, Chief Judge, and EDWARDS and
    SILBERMAN, Senior Circuit Judges.
    Opinion for the Court filed by Chief Judge GARLAND.
    Concurring opinion filed by Senior Circuit Judge
    SILBERMAN.
    GARLAND, Chief Judge: Teachers College, an educational
    institution affiliated with Columbia University, petitions for
    review of a decision of the National Labor Relations Board.
    That decision affirmed an administrative law judge’s conclusion
    that the College violated the National Labor Relations Act by
    refusing to provide information requested by a union
    representing the College’s secretarial and clerical employees.
    The College contends that the union failed to demonstrate the
    relevance of the requested information. As we explain below,
    however, substantial evidence supports the Board’s finding that
    the information was relevant and that the College was obligated
    to provide it. We therefore deny the petition for review and
    grant the Board’s cross-application for enforcement.
    I
    Article I of the collective bargaining agreement (CBA)
    between the College and Local 2110, United Auto Workers,
    recognizes the union as “the exclusive bargaining agent for . . .
    all on campus full-time and part-time . . . secretarial and clerical
    employees.” CBA art. I, ¶ 1 (J.A. 157). Since 2012, the union
    has suspected the College of violating the CBA by transferring
    work reserved to the bargaining unit to non-unit College
    employees. See Email from Jennifer Myers, Local 2110, to
    3
    Randy Glazer, Teachers College (June 13, 2012) (J.A. 397);
    Teachers College, 365 N.L.R.B. No. 86, at 2 (May 31, 2017)
    (ALJ Opinion) (J.A. 463). After communicating these
    suspicions during contract negotiations in the spring of 2012, the
    union filed a formal grievance with the College. See Email from
    Myers to Glazer (Apr. 2, 2012) (J.A. 399); ALJ Opinion, 365
    N.L.R.B. No. 86, at 2 (J.A. 463).
    In its grievance, the union requested a list of “all non-unit
    part-time, casual, hourly, temporary and internship” employees
    and, for each employee, his or her “name, job title/classification,
    department, rate of pay, work schedule, actual number of hours
    worked per week,” and starting and ending dates. See Email
    from Myers to Glazer (Apr. 2, 2012) (J.A. 399). After a few
    weeks of back-and-forth, the College advised the union that it
    was “in the process of gathering items and w[ould] respond to
    [the union’s] requests when that process [wa]s completed.”
    Opinion & Award, Local 2110, UAW v. Teachers College, at 3
    (Mar. 25, 2015) (March 2015 Arbitrator Opinion) (J.A. 188).
    But the College later changed course, saying it believed the
    union was requesting this information only “to support a charge
    of unlawful conduct.” Email from Glazer to Myers (Sept. 7,
    2012) (J.A. 400). As such, the College asserted that it “ha[d] no
    obligation to provide [the requested] information.” 
    Id. The College
    acknowledged that, “if [the union] believe[s]
    that particular work has been improperly transferred out of the
    unit to a non-unit employee in violation of the CBA, this could
    be subject to the grievance and arbitration procedure.” 
    Id. And it
    further acknowledged that, “if a unit position is formally
    assigned a significant responsibility . . . , that position should
    normally maintain that responsibility unless there is good cause
    for it to not be the case.” Email from Glazer to Myers, at 2
    (Dec. 4, 2012) (J.A. 403). Claiming that the CBA permitted the
    shared work responsibilities about which the union complained,
    4
    however, the College denied the grievance in December 2012.
    
    Id. The union
    took the matter to arbitration. In January 2015,
    the arbitrator concluded that the union’s grievance was
    arbitrable under the CBA, and that he “ha[d] the authority to
    determine whether non-bargaining unit employees are
    performing unit work, and/or whether the College has
    transferred unit work to non-unit employees, and to fashion an
    appropriate remedy.” Opinion & Award, Local 2110, UAW v.
    Teachers College, at 12 (Jan. 21, 2015) (January 2015 Arbitrator
    Opinion) (J.A. 185). The arbitrator ordered the parties to agree
    on what information the College would provide the union to
    facilitate further proceedings. March 2015 Arbitrator Opinion,
    at 5 (J.A. 189).
    Following the arbitrator’s order, the union’s counsel sent
    the College’s counsel a more targeted request for information
    regarding non-unit positions it suspected were performing unit
    work. See Letter from Alek Felstiner, Local 2110, to Tara Daub,
    Teachers College, at 1 (Apr. 13, 2015) (J.A. 194). The College
    again refused to provide any information, saying that it would
    not do so unless the union identified for each position “(i) the
    unit work allegedly transferred to such employees; (ii) the basis
    for the Union’s belief that unit work has been transferred to such
    employees; and (iii) the alleged connection between the unit
    work and the information requested.” Letter from Daub to
    Felstiner, at 4 (Apr. 17, 2015) (J.A. 201).
    The union then made two further efforts to address those
    topics. First, in response to the College’s request that the
    arbitrator dismiss the grievance, the union wrote a letter
    explaining at length why it believed the information requested
    was relevant to determining whether the College had
    impermissibly transferred work outside the unit. See Letter from
    5
    Felstiner to Richard Adelman, Arbitrator, at 3-5 (Sept. 10, 2015)
    (J.A. 337-39).
    Second, after the arbitrator rejected the College’s request to
    dismiss the grievance, see Opinion & Award, Local 2110, UAW
    v. Teachers College, at 5 (Sept. 28, 2015) (September 2015
    Arbitrator Opinion) (J.A. 350), the union updated its request yet
    again and in more detail. As the administrative law judge (ALJ)
    summarized:
    [T]he Union had its members canvass the College, and
    review documentary and other evidence in their
    possession regarding what positions were performing
    unit work. Along with the Union’s attorney, they
    compiled a list of nonunit positions that, in the Union’s
    belief, performed unit work, going building by
    building, department by department, and floor by floor.
    The Union’s attorney gathered the information they
    knew about each position, including the title,
    department, and history of the position, and created a
    chart of 34 nonunit positions. Along with a list of the
    position titles, the chart included the department for
    each position, and a short “comments” section setting
    forth the basis for the Union’s belief and/or a
    description of the specific position in question.
    ALJ Opinion, 365 N.L.R.B. No. 86, at 3 (citation omitted) (J.A.
    464).
    On October 22, 2015, the union emailed this chart to the
    College, asking the College to provide the information related
    to the listed positions. The email stated that the union had
    developed the chart by using job postings, information about
    assignment changes from unit employees, and unit employees’
    observations of the job functions non-unit employees were
    6
    performing. See 
    id. The College
    once again accused the union
    of seeking the information for improper purposes and refused to
    budge unless the union further identified the unit work at issue.
    See Letter from Daub to Felstiner, at 4-5 (Oct. 28, 2015) (J.A.
    366-67).
    Three weeks later, the union filed an unfair labor practice
    charge with the National Labor Relations Board (NLRB). After
    a hearing, an ALJ concluded that the College violated section
    8(a)(1) and (5) of the National Labor Relations Act (NLRA), 29
    U.S.C. § 158(a)(1), (5), when it refused to provide the union
    with the information it had requested on October 22, 2015. ALJ
    Opinion, 365 N.L.R.B. No. 86, at 6 (J.A. 467).
    The ALJ found that, by the time of its October 2015
    request, the union “had established and demonstrated to the
    College both the relevance of the requested information and the
    existence of evidence that gave rise to the Union’s reasonable
    belief in the relevance of that information.” 
    Id. at 4
    (J.A. 465).
    The ALJ also concluded that the College had no valid defense
    because it failed to establish that the union’s information request
    was made in bad faith as a discovery substitute for intended
    Board proceedings. 
    Id. at 5
    (J.A. 466). Finally, the judge held
    that the union’s request was not overly broad or unduly
    burdensome because, inter alia, its request was “specifically
    targeted” to the positions identified, and the information was
    “the type of information that would either directly assist the
    Union in the arbitration or assist them in identifying further
    evidence to present to the arbitrator.” 
    Id. On May
    31, 2017, the NLRB affirmed the ALJ’s decision.
    See Teachers College, 365 N.L.R.B. No. 86, at 1 (Board
    Decision) (J.A. 462). The College now petitions for review, and
    the Board cross-applies for enforcement of its order.
    7
    II
    The College challenges the Board’s determination that it
    violated section 8(a)(5) and (1) of the NLRA by refusing to
    produce the information the union requested.
    Section 8(a)(5) imposes on an employer the “duty to
    bargain collectively.” Detroit Edison Co. v. NLRB, 
    440 U.S. 301
    , 303 (1979). That duty “has long been acknowledged to
    include a duty to supply a union with requested information that
    will enable [the union] to negotiate effectively and to perform
    properly its other duties as bargaining representative.” Oil,
    Chem. & Atomic Workers Local Union No. 6-418 v. NLRB, 
    711 F.2d 348
    , 358 (D.C. Cir. 1983) (internal quotation marks
    omitted). “Because a union’s other duties include the duty to
    see to it that an employer meets its [collective bargaining
    agreement] obligations, the employer’s duty to furnish
    information extends to data requested in order properly to
    administer and police a collective bargaining agreement.” N.Y.
    & Presbyterian Hosp. v. NLRB, 
    649 F.3d 723
    , 729 (D.C. Cir.
    2011) (citation and internal quotation marks omitted).
    “[T]he duty imposed by section 8(a)(5) is subject to a
    minimum standard of relevance: ‘The union’s need and the
    employer’s duty depend, in all cases, on the probability that the
    desired information [is] relevant, and that it [will] be of use to
    the union in carrying out its statutory duties and
    responsibilities.’” 
    Id. at 729-30
    (quoting Oil, Chem. & Atomic
    
    Workers, 711 F.2d at 359
    ). The requisite showing of relevance
    depends on whether the union is requesting information about
    employees who are part of the bargaining unit or outside it.
    “For information about employees in the bargaining unit, it is
    presumed that the requested information is relevant . . . , and the
    employer must provide the information unless it can show the
    information is irrelevant.” U.S. Testing Co. v. NLRB, 
    160 F.3d 8
    14, 19 (D.C. Cir. 1998). With respect to employees outside the
    bargaining unit, “the burden is on the union to demonstrate the
    relevance of [the requested] information.” Id.; see N.Y. &
    Presbyterian 
    Hosp., 649 F.3d at 730
    .
    In this case, the union sought information regarding
    employees outside the bargaining unit in order to determine
    whether the employer was improperly transferring unit work to
    them. Accordingly, the burden was on the union to demonstrate
    the relevance of the information. Thus, a “bare assertion that it
    needs information” would be insufficient; the union needed to
    “explain to the employer why the information is 
    relevant.” 649 F.3d at 730
    . “Nevertheless,” as we explained in Presbyterian
    Hospital, “the threshold for relevance is low. In particular, the
    union need not demonstrate the existence of some particular
    controversy or the need to dispose of some recognized problem.
    Rather, we apply a discovery-type standard, under which [t]he
    fact that the information is of probable or potential relevance is
    sufficient to give rise to an obligation” to provide it. 
    Id. (citations and
    internal quotation marks omitted); see NLRB v.
    Acme Indus. Co., 
    385 U.S. 432
    , 437 & n.6 (1967); Brewers &
    Maltsters, Local Union No. 6 v. NLRB, 
    414 F.3d 36
    , 45 (D.C.
    Cir. 2005); Oil, Chem. & Atomic 
    Workers, 711 F.2d at 359
    .
    The Board’s factual findings are conclusive if supported by
    “substantial evidence on the record considered as a whole.” 29
    U.S.C. § 160(e). “Under this standard, ‘the Board is to be
    reversed only when the record is so compelling that no
    reasonable factfinder could fail to find to the contrary.’” Pub.
    Serv. Co. v. NLRB, 
    843 F.3d 999
    , 1004 (D.C. Cir. 2016)
    (quoting Fort Dearborn Co. v. NLRB, 
    827 F.3d 1067
    , 1072
    (D.C. Cir. 2016)). And, “[b]ecause Congress has determined
    that the Board has the primary responsibility of marking out the
    scope . . . of the statutory duty to bargain, great deference is due
    to the Board’s determinations of the scope of an employer’s
    9
    obligation to provide requested information to a union,” as that
    obligation “derive[s] from the statutory duty to bargain.” 
    Id. (internal quotation
    marks omitted).
    A
    The College’s principal contention is that substantial
    evidence does not support the Board’s finding that the union met
    its burden to demonstrate the relevance of the information it
    sought. We disagree.
    1. As just noted, the courts and the Board apply a
    “discovery-type” standard, under which “[t]he fact that the
    information is of probable or potential relevance is sufficient to
    give rise to an obligation” to provide it. N.Y. & Presbyterian
    
    Hosp., 649 F.3d at 730
    (internal quotation marks omitted); see,
    e.g., 
    Acme, 385 U.S. at 437
    & n.6. All that is required is “a
    reasonable belief, supported by objective evidence, that the
    requested information is relevant.” Disneyland Park, 
    350 N.L.R.B. 1256
    , 1257-58 (2007). Under this standard, substantial
    evidence amply supports the ALJ’s finding that, “by the time of
    its October 22, 2015 information request, the Union had
    established and demonstrated to the College both the relevance
    of the requested information and the existence of evidence that
    gave rise to the Union’s reasonable belief in the relevance of
    that information.” ALJ Opinion, 365 N.L.R.B. No. 86, at 4 (J.A.
    465).
    As the ALJ explained, in early 2015, “the arbitrator
    determined that he had the authority to determine whether
    nonbargaining unit employees were performing bargaining unit
    work, and/or whether the College transferred unit work to non-
    unit employees, and to fashion an appropriate remedy.” 
    Id. Thereafter, “[r]elying
    upon information received from union
    members [who] canvass[ed] the College in October 2015, along
    10
    with job postings and other documents in the Union’s
    possession, the Union identified 34 nonunit positions it believed
    were performing bargaining unit work.” 
    Id. It then
    compiled
    this information into a chart that listed, for each such position,
    “to the best of its knowledge, the position name and department,
    and included a ‘comment’ section describing the specific
    position in question, or identifying the basis of the Union’s
    belief that the position was performing unit work.” 
    Id. On October
    22, 2015, the union emailed the chart to the
    College. Email from Felstiner to Daub (Oct. 22, 2015) (J.A.
    359) (attaching List of Positions Chart (J.A. 360-61)). The
    email stated the union’s belief “that the College has improperly
    transferred bargaining unit work to employees in these
    positions.” 
    Id. The email
    further advised the College that, as
    recounted above, the “comments” column of the chart included
    “a brief note reflecting the basis for the Union’s belief that the
    College improperly transferred unit work to the position(s) in
    question.” 
    Id. And it
    explained to the College how the union
    developed the information. 
    Id. The chart,
    and the work the union undertook to construct it,
    provide sufficient support for the ALJ’s finding that the union
    had, and presented to the College, a reasonable belief that unit
    work was being performed outside the unit -- a concern that was
    directly relevant to its grievance. See ALJ Opinion, 365
    N.L.R.B. No. 86, at 4 (J.A. 465). As we have noted, the CBA
    recognized the union as “the exclusive bargaining agent for . . .
    all on campus full-time and part-time . . . secretarial and clerical
    employees.” CBA art. I, ¶ 1 (J.A. 157). It further defined
    “secretarial and clerical employees” as
    including clerks, account clerks, secretaries,
    receptionist-typists, clerk-typists, assistant supervisors
    in the Word Processing Center, correspondence clerks,
    11
    postal clerks, library assistants, personnel assistants,
    duplicating equipment operators, electronic data
    processing machine operators, bookkeeping machine
    operators, bookkeeping machine operator supervisors,
    key-punch operators, key-punch operator supervisors,
    audiovisual technicians, student financial aid
    counselors, cashiers, and telephone operators . . . .
    
    Id. And the
    chart showed -- based on canvassing, job postings,
    and other documents -- numerous non-unit positions that
    appeared, at least on their face, to involve the bargaining unit
    work of “secretarial and clerical employees.” Those included:
    five “secretary” positions and four positions previously filled by
    secretaries; three “front desk” positions and a fourth with “front
    desk” duties included in its job description, positions that were
    traditionally and reasonably associated with receptionist or
    secretarial work; two interim bookkeeping “clerk” positions; as
    well as other positions that reasonably appeared to be included
    within the definition of “secretarial and clerical employees”
    quoted above. See List of Positions Chart (J.A. 360-61).
    The union’s October 22 email asked the College to provide
    the following information for each of the 34 positions listed in
    the chart: (1) the title of the position; (2) the name or names of
    employee(s) filling the position; (3) the position type; (4) the
    department; (5) the regular schedule for the position; (6) the rate
    of pay; and (7) the current or past job descriptions. Email from
    Felstiner to Daub (Oct. 22, 2015) (J.A. 359). It is obvious to us,
    as it was to the ALJ, that this kind of information was relevant
    for processing the grievance and preparing for arbitration on the
    issue, both of which are central to the union’s “carrying out its
    statutory duties and responsibilities,” 
    Acme, 385 U.S. at 437
    .
    See ALJ Opinion, 365 N.L.R.B. No. 86, at 4 (J.A. 465).
    12
    Indeed, in Presbyterian Hospital, we said as much
    regarding a union’s request for information including non-unit
    “nurse practitioners’ names . . . ; the departments or units where
    the nurse practitioners are assigned to work; their job duties and
    their start dates at the 
    hospital.” 649 F.3d at 727
    (internal
    quotation marks omitted). “There can be little dispute,” we said,
    that the information request “is relevant to the question whether
    non-bargaining unit [nurse practitioners] are performing
    bargaining unit work,” and so “the [h]ospital was obligated to
    provide [the information].” 
    Id. at 730.
    The same is true here.
    2. We find unpersuasive the College’s efforts to downplay
    the sufficiency of the union’s showing.
    The College argues that the union did not possess “objective
    evidence” of the relevance of its information requests “at the
    time of its request[s].” Reply Br. 1 (quoting Pub. Serv. 
    Co., 843 F.3d at 1005
    ; N.Y. & Presbyterian 
    Hosp., 649 F.3d at 731
    ). It
    charges that “Union counsel testified that he had no knowledge
    or belief, at the time he prepared and sent his October 2015 chart
    to Teachers College, as to what job duties the non-unit positions
    listed in the chart were performing or whether the union
    believed that any duties they performed were ‘unit work.’”
    College Br. 27 (citing ALJ Hearing Tr. 62-65, 125-26 (J.A. 42-
    45, 86-87)). But this contention mischaracterizes the testimony:
    union counsel said only that he could not “speak to the Union’s
    knowledge as of November 20, 2014,” ALJ Hearing Tr. 65
    (emphasis added) (J.A. 45) -- nearly a year before the October
    2015 information request at issue here.
    The parties agree that a union seeking information that is
    not presumptively relevant (as here) must “explain why the
    information is relevant” and must be able to support that
    explanation “with objective evidence.” College Br. 26-27;
    NLRB Br. 18-19; see N.Y. & Presbyterian 
    Hosp., 649 F.3d at 13
    730; Disneyland 
    Park, 350 N.L.R.B. at 1258
    . The College
    further contends, however, that a union must not only explain
    relevance and possess objective evidence, but must also present
    that evidence to the employer at the time of its request. The
    NLRB disagrees.1 Regardless of whether the College is correct
    on this front, the union has satisfied that requirement in this
    case. As of the date of the request, the union did have and did
    present the College with objective evidence: the member
    canvass and the postings to which it referred in its October 2015
    email and chart. See ALJ Opinion, 365 N.L.R.B. No. 86, at 3
    (J.A. 464). That evidence was sufficient.2

    objective, factual basis for [its belief] . . . . Under current Board law,
    however, the union is not obligated to disclose those facts to the
    employer at the time of the information request. Rather, it is sufficient
    that the General Counsel demonstrate at the hearing that the union
    had, at the relevant time, a reasonable belief.”); accord DirectSat USA,

    The College also complains that the chart proffered by the
    union was too “conclusory.” College Br. 44; see 
    id. at 26-27.
    The chart, the College says, “provided only a list of 34 vaguely
    identified non-unit positions.” 
    Id. at 33.
    Again, we disagree.
    For each of the 34 positions, the union named the position and
    the department in which it was located. The chart’s comments
    section added additional information, where available to the
    union, including the position’s physical location, its history, and
    whether it was listed in the College’s job postings.
    The College says that many of the 34 positions listed in the
    chart used imprecise or inaccurate job titles. But to the extent
    the union’s proffer reflected incomplete information about the
    identified work transfers, that lack of knowledge was precisely
    the reason for the information request and does not, as the
    College insists, prove that the union had “no good faith basis for
    the grievance,” 
    Id. at 8.
    See Crowley Marine Servs., Inc. v.
    NLRB, 
    234 F.3d 1295
    , 1296 (D.C. Cir. 2000) (upholding the
    Board’s finding of a violation where “the information was
    sought and needed to enable the Union to make an informed
    judgment” about pursuing contract violation remedies (internal
    quotation marks omitted)); Shoppers Food Warehouse, 
    315 N.L.R.B. 258
    , 259 (1994) (“The Union was not required to show
    that the information which triggered its request was accurate or
    ultimately reliable, and a union’s information request may be
    based on hearsay.”).
    Nor did the College, at any time, present any evidence
    contradicting the union’s characterization of the referenced job
    postings. Instead, it disclaimed any duty to look into the union’s
    allegations before refusing its request, unless the union met the
    College’s demands for greater specificity. See Recording of
    Oral Arg. 28:03-29:20. Indeed, after repeated questioning at
    oral argument, it was unclear whether the College had even
    bothered to review the job postings mentioned in the October
    15
    2015 chart. As the Seventh Circuit said in NLRB v. George
    Koch Sons, Inc.: “It was reasonable for the Union to rely on the
    . . . observations of union officials, employee reports and records
    in forming its reasonable suspicion that the [employer] was
    diverting work to [a nonunion business the employer operated].
    Therefore, considering that [the employer] did not present any
    evidence contradicting the contents of these reports and
    observations, [they] alone constitute substantial evidence . . .
    that the Union reasonably suspected that [the employer] was
    diverting work” in violation of the CBA. 
    950 F.2d 1324
    , 1333
    (7th Cir. 1991) (citations omitted).
    The College also argues that the chart’s listings were
    insufficient because Article I of the CBA “defines the
    bargaining unit by titles, not by the type of work done by the
    employees.” College Br. 30 n.5. This argument is somewhat
    confusing, given that the College’s human resources director
    acknowledged that allegations “that particular work has been
    improperly transferred out of the unit . . . could be subject to the
    grievance and arbitration procedure.” Email from Glazer to
    Myers (Sept. 7, 2012) (J.A. 400). It also disregards those chart
    listings that appear to describe positions by titles. The college
    further argues that, even if the unit is defined by job duties
    rather than titles, the cited duties are not exclusive to the unit
    under the CBA.
    In any event, both of these arguments go to the merits of the
    union’s grievance, upon which the Board does not pass in
    assessing the relevance of the requested information. Bell Tel.
    Labs., Inc., 
    317 N.L.R.B. 802
    , 803 (1995), enforced, 
    107 F.3d 862
    (3d Cir. 1997). As the Supreme Court has explained:
    [W]hen it order[s] the employer to furnish the
    requested information to the union, the Board [is] not
    making a binding construction of the labor contract. It
    16
    [is] only acting upon the probability that the desired
    information [is] relevant, and that it would be of use to
    the union in carrying out its statutory duties and
    responsibilities.     This discovery-type standard
    decide[s] nothing about the merits of the union’s
    contractual claims.
    
    Acme, 385 U.S. at 437
    . The union was “not required to accept”
    the College’s view of the CBA; it “was entitled to conduct its
    own investigation and reach its own conclusions about the
    applicability of the agreement.” Shoppers Food 
    Warehouse, 315 N.L.R.B. at 259
    .
    3. Finally, the College maintains that, “[i]n its prior
    decisions, the Board has made clear that this type of showing is
    insufficient to establish relevance.” College Br. 34. The prior
    decisions it cites are inapposite.
    The College cites Disneyland Park, in which the “Board
    held that the agent’s ‘testimony did not explain how the
    requested information would be relevant to support an arguable
    violation of the contract,’ and thus could not ‘serve to establish
    that the Union provided to the Respondent a sufficient factual
    basis to establish relevance at the time the information request
    was made.’” 
    Id. at 36
    (quoting Disneyland 
    Park, 350 N.L.R.B. at 1259
    ). According to the College, the “exact same analysis
    applies here.” 
    Id. But it
    does not. In Disneyland Park, the
    union requested information about non-unit employees to whom
    the CBA expressly permitted the employer to subcontract 
    work. 350 N.L.R.B. at 1258-59
    . Here, by contrast, the union points to
    CBA language that is reasonably read as reserving to the unit the
    work it believes was transferred. Indeed, the arbitrator
    repeatedly stated that the union had presented an arbitrable
    grievance regarding the transfer of unit work. See, e.g., January
    2015 Arbitrator Opinion, at 12 (J.A. 185); September 2015
    17
    Arbitrator Opinion, at 4 (J.A. 349) (stating that “the Union may
    be able to prove some contract violation”).
    The College also cites Postal Service, 
    310 N.L.R.B. 701
    (1993), for the proposition that “vague, general reports” are
    insufficient to show relevance. College Br. 35 (quoting Postal
    
    Serv., 310 N.L.R.B. at 703
    ). But in that case, the union’s basis
    for requesting information about supervisors it thought might
    have engaged in conduct similar to that for which an employee
    was disciplined was “nothing more than that, at a union meeting,
    employees had furnished supervisors’ names in response to an
    appeal for the names of those who had had ‘prolonged
    absences.’” Postal 
    Serv., 310 N.L.R.B. at 703
    . Here, by
    contrast, far from presenting the College with “vague, general
    reports,” the union explained that its allegations were founded
    on (1) a broad survey of unit members, who reported multiple
    instances of improper work transfers, and (2) the College’s own
    job postings. Union counsel Alek Felstiner testified before the
    ALJ as follows:
    After the arbitrator’s decision [declining to dismiss the
    grievance], I met with Union members twice; groups of
    Union members at Teachers College, and they
    essentially canvassed the college and also surveyed
    documentary evidence, information that they had, in
    order to compile this list . . . and identify sort of
    building by building, floor by floor, department by
    department which positions the Union believed were
    performing unit work even though the positions were
    not in the unit.
    ALJ Hearing Tr. 50 (J.A. 33).
    4. In sum, substantial evidence supports the NLRB’s
    determination that the union had adequate and objective
    18
    evidence to support a reasonable belief that the requested
    information was relevant to its pending grievance. What really
    appears to underlie the College’s argument is an implied claim
    that evidence satisfying more than a “discovery-type” standard
    is required. But that is a claim our precedent rejects.
    B
    The College challenges the Board’s decision on two
    additional, but equally unpersuasive, grounds.
    First, the College contends that the record compels the
    conclusion that the union requested the information in bad faith.
    Under Board precedent, a union may not use an information
    request, ostensibly made for purposes of policing a collective-
    bargaining agreement, as a discovery device to pursue
    proceedings before the NLRB. Union Tribune Publ’g Co., 
    307 N.L.R.B. 25
    , 26 (1992) (holding that, because Board procedures
    do not include prehearing discovery, a party may not use an
    information request to “impose a discovery requirement where
    none otherwise exists”), enforced, 
    1 F.3d 486
    (7th Cir. 1993);
    WXON-TV, Inc., 
    289 N.L.R.B. 615
    , 617-18 (1988), enforced,
    
    876 F.2d 105
    (6th Cir. 1989). “An employer charged with
    failing to provide requested information may argue as an
    affirmative defense that the request was made in bad faith . . . .”
    Monmouth Care Ctr. v. NLRB, 
    672 F.3d 1085
    , 1094 (D.C. Cir.
    2012). “But the employer bears the burden of persuasion on that
    defense,” 
    id., and substantial
    evidence supports the NLRB’s
    determination that the College failed to satisfy that burden.
    Much of the College’s argument on this point is a repetition
    of its claim that the union had no reasonable basis for believing
    that work had been transferred out of the unit, and hence no
    basis for requesting the information as relevant. The “Union’s
    inability to show an objective basis for the relevance of its
    19
    requests,” the College insists, “compels the conclusion that the
    Union’s real objective is to prepare to use Board procedures for
    organizing or accreting non-unit positions into the bargaining
    unit.” College Br. 42. But we have rejected the contention that
    the union was unable to show relevance, and thus that claimed
    inability can hardly form the basis for an affirmative defense of
    bad faith.
    The College also claims that the union openly “admitted its
    intent was to either pursue [an unfair labor practice] charge
    against Teachers College for ‘unlawful’ conduct or to file a unit
    clarification petition to accrete non-unit positions into the
    Union’s unit . . . , despite their express exclusion from the scope
    of the CBA’s recognition clause.” 
    Id. at 4
    0. That assertion rests
    on correspondence from three years before the October 2015
    request, in which the union filed a grievance stating that the
    College had improperly excluded positions from the unit. See
    Email from Myers to Glazer (Apr. 2, 2012) (J.A. 399). In the
    same correspondence chain, the union stated that the grievance
    included the improper work transfers. See Email from Myers to
    Glazer (June 13, 2012) (J.A. 397). Indeed, it pursued that work-
    transfer grievance to arbitration. And, as the ALJ pointed out,
    “at the time of the information request, there were no
    outstanding charges or complaints pending before the Board.”
    ALJ Opinion, 365 N.L.R.B. No. 86, at 5 (J.A. 466). To the
    contrary, the only ongoing proceeding when the union made its
    October 22, 2015 request was the arbitration. In that context,
    the three-year-old correspondence does not satisfy the College’s
    burden to show the union’s bad faith.
    Second, the College argues that, “even if, arguendo, the
    Union demonstrated relevance with respect to certain positions,”
    the union failed to establish the relevance of each type of
    information it requested for each individual position in its
    October 2015 chart. College Br. 43. As to this argument, our
    20
    analysis can be brief. In its exceptions below, the College did
    not challenge or dispute the request as it applied to any specific
    position. See College Br. in Supp. of Exceptions 20-21 (J.A.
    446-47). We therefore may not consider such challenges now.
    See 29 U.S.C. § 160(e); 
    Monmouth, 672 F.3d at 1094
    .
    III
    For the foregoing reasons, we deny the petition for review
    and grant the Board’s cross-application for enforcement.
    So ordered.
    SILBERMAN, Senior Circuit Judge, concurring: I am in full
    agreement with the court’s reasoning. I write separately to
    contest the reasonableness of the Board’s view expressed in
    Piggly Wiggly Midwest, LLC, 
    357 N.L.R.B. 2344
    , 2344 (2012),
    which we note in footnote 1 but upon which we do not rely. The
    Board there said that although a union seeking information
    concerning non-bargaining unit activities must have a factual
    basis to support the relevance to the bargaining unit of that
    information, it need not disclose those facts to the employer; it
    is sufficient that the General Counsel present those facts to the
    ALJ at an unfair labor practice hearing.
    I think that is a paradigmatic example of arbitrary and
    capricious decision-making. An employer under Board law
    must accommodate a union’s request for non-bargaining unit
    information if it is relevant to bargaining unit concerns, but can
    legitimately refuse if the union has no factual basis for asserting
    that relevance. That decision must be made at the time of the
    union’s request, and if the employer is wrong, it violates the law.
    It seems to me to be absurd for the Board to hold that an
    employer who is not faced with alleged facts supporting a
    union’s claim of relevance at the time of the request – and
    therefore apparently acting within the law – can be retroactively
    determined to have violated the Act by virtue of factual evidence
    first put on by the General Counsel at a hearing before an ALJ.
    This seems to even raise an issue of due process.
