    Before MARTIN, ANDERSON and BLACK, Circuit Judges.
    BLACK, Circuit Judge:
    Case: 15-10291     Date Filed: 10/03/2016   Page: 2 of 55
    Mercedes-Benz U.S. International, Inc. (MBUSI) petitions this Court to
    review the order of a three-member panel of the National Labor Relations Board
    (NLRB or the Board) modifying and adopting as modified the recommended order
    of the administrative law judge (ALJ). The Board found that MBUSI violated the
    National Labor Relations Act, 29 U.S.C. § 151 et seq. (the Act), in three ways:
    (1) maintaining an overly broad solicitation and distribution rule that employees
    would reasonably understand to prohibit solicitation in work areas by employees
    not on working time of other employees not on working time; (2) prohibiting an
    employee not on working time from distributing union literature in one of
    MBUSI’s team centers, which are mixed-use areas; and (3) prohibiting employees
    not on working time from distributing union literature in the MBUSI atrium, which
    is a mixed-use area. Mercedes-Benz U.S. Int’l, Inc., 361 N.L.R.B. No. 120 (Nov.
    26, 2014). On petition for review, MBUSI challenges each of these findings, and
    the General Counsel of the NLRB cross-petitions this Court to enforce the Board’s
    order. The Union, United Automobile, Aerospace, and Agricultural Implement
    Workers of America (UAW), intervenes in support of the order. After review, we
    enforce in part and remand in part with instructions.
    I. BACKGROUND
    First enacted in 1935, “a primary purpose of the National Labor Relations
    Act was to redress the perceived imbalance of economic power between labor and
    2
    Case: 15-10291     Date Filed: 10/03/2016    Page: 3 of 55
    management.” Am. Ship Bldg. Co. v. NLRB, 
    380 U.S. 300
    , 316, 
    85 S. Ct. 955
    , 966
    (1965). The Act “sought to accomplish that result by conferring certain affirmative
    rights on employees and by placing certain enumerated restrictions on the activities
    of employers.” 
    Id. Section 7
    of the Act grants employees affirmative rights such
    as the right to self-organize, to bargain collectively, “and to engage in other
    concerted activities for the purpose of collective bargaining or other mutual aid or
    protection.” National Labor Relations (Wagner-Connery Labor Relations) Act § 7,
    29 U.S.C. § 157. Section 8 of the Act defends the Section 7 rights by prohibiting
    an employer’s “interfer[ing] with, restrain[ing], or coerc[ing] employees in the
    exercise of the rights guaranteed in [Section 7].” 
    Id. § 8,
    29 U.S.C. § 158(a)(1).
    The Act also created and empowered the modern NLRB. See 29 U.S.C.
    §§ 153–156. Within the NLRB, the Act created the office of the General Counsel,
    which has final authority regarding investigations into unfair labor practices and
    prosecution of complaints before the Board. 
    Id. § 153(d).
    The Supreme Court has
    described the Board’s role in interpreting and applying the Act as follows:
    The Wagner Act did not undertake the impossible task of specifying
    in precise and unmistakable language each incident which would
    constitute an unfair labor practice. On the contrary that Act left to the
    Board the work of applying the Act’s general prohibitory language in
    the light of the infinite combinations of events which might be
    charged as violative of its terms. Thus a rigid scheme of remedies is
    avoided and administrative flexibility within appropriate statutory
    limitations obtained to accomplish the dominant purpose of the
    legislation.

    Republic Aviation Corp. v. NLRB, 
    324 U.S. 793
    , 798, 
    65 S. Ct. 982
    , 985 (1945)
    (quotation marks omitted).
    Applying Section 8 to a common issue, the Board has long held that an
    employer may not prohibit union solicitation by employees who are not on
    working time 1 irrespective of whether they are in working or non-working areas of
    the employer’s property. Stoddard-Quirk Mfg. Co., 
    138 N.L.R.B. 615
    , 621 (1962).
    An employer also may not prohibit distribution of union literature by employees
    who are in non-working areas and not on working time. 
    Id. An employer
    may
    prohibit distribution in working areas, however, because “the employer’s interest
    in cleanliness, order, and discipline [in a working area] is undeniably greater than it
    is in nonworking areas.” 
    Id. at 620.
    This petition involves MBUSI’s alleged
    interference with protected solicitation and distribution in violation of Section 8.
    A. The MBUSI Solicitation and Distribution Rule
    In Vance, Alabama, MBUSI operates two plants at which it manufactures
    luxury automobiles. In May 2012, the UAW began a campaign to unionize
    MBUSI’s employees in Vance. MBUSI has a policy of strict neutrality with
    respect to unionization but maintains rules regarding solicitation and distribution of
    non-work related material by employees on MBUSI property. In pertinent part and
    1
    “Working time” refers to “periods when employees are performing actual job duties,
    periods which do not include the employees’ own time such as lunch and break periods.” See
    Our Way, Inc., 
    268 N.L.R.B. 394
    , 395 (1983).
    4
    Case: 15-10291    Date Filed: 10/03/2016    Page: 5 of 55
    for the pertinent time period, MBUSI’s solicitation and distribution rule read as
    follows:
    MBUSI prohibits solicitation and/or distribution of non-work related
    materials by Team Members during work time or in working areas.
    The General Counsel contends that this rule is overly broad because an employee
    would reasonably interpret the rule to prohibit protected union solicitation.
    Specifically, while an employer may not prohibit union solicitation in a working
    area by an employee not on working time of an employee not on working time, the
    final “or” in MBUSI’s written rule suggests that MBUSI bars all solicitation in
    working areas.
    B. MBUSI Team Centers
    The MBUSI plant at issue in this case has 19 team centers, 15 of which are
    immediately adjacent to the production line and all of which are adjacent to the
    logistics aisle, an indoor path used by forklifts and other motorized vehicles to
    transport parts in the assembly area. The few team centers that are not
    immediately adjacent to the production line are between 10 and 60 feet from the
    production line. Some team centers are completely or partially walled, while other
    team centers are separated from the production line by chains.
    Team centers serve several functions in the MBUSI production process.
    They serve as offices for Group Leaders and Team Leaders and as observation
    posts for engineers and quality personnel. From the team centers, these personnel
    5
    Case: 15-10291     Date Filed: 10/03/2016   Page: 6 of 55
    supervise a wide variety of aspects of production along the line, including quality,
    performance, machinery and tools, parts and equipment, output, shift assignments,
    and safety. Team centers also serve as second offices for human resources staff
    and upper management. Finally, at the beginning of each shift, Group Leaders use
    team centers to conduct pre-production meetings, after which the incoming shift
    relieves the outgoing shift. Employees often gather in their team center for an
    indeterminate period before the pre-production meeting and may use the team
    center during shift and meal breaks (although about half eat in MBUSI’s on-site
    cafeteria).
    MBUSI’s policy is to treat team centers as work areas when the production
    line is running and as non-work areas when the production line is halted.
    Typically, the production line runs 24 hours a day, 7 days a week, except for 30-
    minute meal breaks, 10-minute shift breaks, and a brief pause during a shift
    change. Per MBUSI policy, only during production line pauses (i.e. shift and meal
    breaks) may MBUSI employees distribute non-work literature to other MBUSI
    employees in the team centers.
    On June 20, 2013, employee David Gilbert went to his team center a few
    minutes before his shift began. Gilbert’s team center is completely walled and
    approximately 10 feet from the production line. In the team center, Gilbert
    distributed copies of a pro-union flyer to other off-duty employees. Gilbert’s Team
    6
    Case: 15-10291     Date Filed: 10/03/2016   Page: 7 of 55
    Leader and a human resources representative each separately spoke with Gilbert
    and informed him that he was not permitted to distribute literature in the team
    center while the production line was moving. Gilbert was not disciplined, and the
    conversation was polite and non-threatening.
    C. The MBUSI Atrium
    The MBUSI atrium is the first room that an employee enters after arriving
    for work, parking, and passing through a security turnstile. The atrium is
    approximately 60 feet wide by 100 feet long. In the atrium, MBUSI maintains a
    security kiosk, a merchandise store, a medical office, a vehicle leasing desk, and an
    Alabama Credit Union branch. MBUSI uses the atrium to provide company and
    employee information through bulletin boards and television monitors. Because it
    accommodates several hundred employees beginning and ending their shift each
    day, the atrium becomes extremely congested and busy during shift change.
    In late August, 2013, Gilbert, Kirk Garner, and several other MBUSI
    employees were distributing UAW handbills in the atrium during a shift change.
    Two MBUSI human resources representatives approached Garner and informed
    him that MBUSI prohibits distribution of literature in the atrium. A few hours
    later, the human resources representatives met with Garner and told him that
    MBUSI management had decided to permit distribution of literature in the atrium.
    Garner, a member of the UAW leadership council, informed Gilbert and
    7
    Case: 15-10291      Date Filed: 10/03/2016   Page: 8 of 55
    understood from that conversation that employees were thereafter permitted to
    distribute literature in the atrium.
    II. PROCEDURAL HISTORY
    On September 3, 2013, Garner initiated the underlying action charging
    MBUSI with unfair labor practices. On February 21, 2014, the General Counsel
    consolidated Garner’s charge with two charges filed by the UAW in October 2013
    and January 2014 respectively. The ALJ conducted a three-day hearing in April
    2014 and issued his decision in July 2014. The ALJ found that MBUSI had
    violated the act as follows:
    (a) Maintaining an overly broad solicitation and distribution rule
    which employees reasonably would understand to prohibit
    solicitation, in work areas, by employees not on working time of other
    employees not on working time.
    (b) Prohibiting an employee not on working time from distributing
    union literature in one of [MBUSI’s] team centers, which are mixed
    use areas within [MBUSI’s] plant.
    (c) Prohibiting employees not on working time from distributing
    union literature in the atrium, which is a mixed use area within
    [MBUSI’s] plant.
    Among other things, the ALJ recommended that the Board order MBUSI to
    rescind its written solicitation and distribution rule and to cease and desist from
    prohibiting distribution of literature in the team centers and atrium by employees
    not on working time of employees not on working time.
    8
    Case: 15-10291       Date Filed: 10/03/2016       Page: 9 of 55
    MBUSI filed with the Board 22 exceptions to the ALJ’s order. In its brief,
    MBUSI primarily argued that the ALJ had misapplied the law regarding MBUSI’s
    written solicitation and distribution policy, the team centers are work areas when
    the production line is moving, certain employees were not supervisors, and the
    atrium incident could not be a violation in light of its de minimis impact. On
    November 26, 2014, the Board affirmed the ALJ’s decision and adopted the ALJ’s
    proposed order with a slight modification to the remedy. 2 In a footnote, the Board
    noted that one member of the Board found it “unnecessary to pass on the status of
    [MBUSI’s] team centers that are adjacent to its production line.”
    On January 23, 2015, MBUSI filed with this Court a petition for review of
    the Board’s order (the Order). On February 9, 2015, the General Counsel filed a
    cross-petition for enforcement.
    MBUSI contends the Board erred in finding that MBUSI’s written
    solicitation and distribution policy was unlawful because MBUSI could and did
    rebut the presumption that its ambiguous rule interfered with or restrained
    protected activity. Additionally, MBUSI insists the Order is overly broad in
    imposing a remedy as to all team centers after explicitly considering only the team
    center in which Gilbert was censured. MBUSI states more broadly that the
    2
    The Board ordered that MBUSI rescind its written solicitation and distribution rule and
    gave MBUSI a few options to replace or amend its employee handbook. The Board also
    required MBUSI to file a sworn certification with the NLRB attesting to the steps it has taken to
    comply with the order.
    9
    Case: 15-10291     Date Filed: 10/03/2016    Page: 10 of 55
    Board’s mixed-use findings as to both the team centers and the atrium represent an
    unexplained departure from precedent. MBUSI also contends the Board erred in
    failing to find special circumstances justifying the prohibition on distribution of
    literature in team centers when the production line is moving.
    The General Counsel answers that the Board need not find that MBUSI’s
    employees subjectively believed the policy prohibited protected activity. Rather,
    the test is objective, and an employer’s mere maintenance of an overly broad rule
    constitutes a violation. As to the team centers, the General Counsel contends the
    Order was consistent with precedent holding “[w]here an employer permits both
    work and non-work activities of a non-incidental nature to occur in the same area,
    the Board properly deems it a mixed use area.” Likewise, the General Counsel
    states that MBUSI failed to support its special circumstances argument and the
    ALJ’s decision was not limited to the team center in which Gilbert was censured.
    Finally, the General Counsel contends MBUSI waived its right to challenge the
    ALJ’s finding that the atrium is a mixed-use area by failing to raise it to the Board
    in MBUSI’s exceptions to the ALJ’s proposed order.
    MBUSI replies that its failure to challenge the ALJ’s holding was excused
    by “extraordinary circumstances.” Specifically, while the ALJ found a violation
    notwithstanding the de minimis effect of MBUSI’s interference, the Board changed
    10
    Case: 15-10291     Date Filed: 10/03/2016    Page: 11 of 55
    the rationale for MBUSI’s violation and found a violation due to interference that
    was not de minimis.
    III. STANDARD OF REVIEW
    The Court reviews de novo the Board’s legal conclusions and reviews for
    substantial evidence the Board’s findings of fact. See NLRB v. Babcock & Wilcox
    Co., 
    351 U.S. 105
    , 112, 
    76 S. Ct. 679
    , 684 (1956). “[A]n administrative order
    cannot be upheld unless the grounds upon which the agency acted in exercising its
    powers were those upon which its action can be sustained.” SEC v. Chenery
    Corp., 
    318 U.S. 80
    , 95, 
    63 S. Ct. 454
    , 462 (1943). In other words, we may not
    enforce an order of the NLRB on alternate grounds without remanding to the
    Board for further consideration. See First Nat. Maint. Corp. v. NLRB, 
    452 U.S. 666
    , 672 n.6, 
    101 S. Ct. 2573
    , 2577 (1981).
    “[I]n light of its experience,” the Board may fashion general rules and
    presumptions regarding the lawfulness of employer restrictions “without the
    necessity of proving the underlying generic facts which persuaded it to reach that
    conclusion.” Beth Israel Hosp. v. NLRB, 
    437 U.S. 483
    , 493, 
    98 S. Ct. 2463
    , 2470
    (1978). Where the Board departs from prior decisions, however, it must explain
    the reasons for the new approach. NLRB v. Sunnyland Packing Co., 
    557 F.2d 1157
    , 1160 (5th Cir. 1977) (“[A]n agency must either conform itself to its own
    prior decisions or else explain the reason for its departure.”); see also Sharron
    11
    Case: 15-10291       Date Filed: 10/03/2016      Page: 12 of 55
    Motor Lines, Inc. v. United States, 
    633 F.2d 1115
    , 1117 (5th Cir. 1981) (“[L]aw
    does not permit an agency to grant one person the right to do that which it denies to
    another similarly situated. There may not be a rule for Monday, another for
    Tuesday, a rule for general application, but denied outright in a specific case.”
    (quoting Mary Carter Paint Co. v. FTC, 
    333 F.2d 654
    , 660 (5th Cir. 1964) (Brown,
    J., concurring))).3 Therefore, while we defer to the Board’s rational constructions
    of the Act, Ga. Power Co. v. NLRB, 
    427 F.3d 1354
    , 1358 (11th Cir. 2005), such
    deference does not extend to unexplained deviations from prior Board precedent,
    Sunnyland Packing 
    Co., 557 F.2d at 1160
    ; NLRB v. WGOK, Inc., 
    384 F.2d 500
    ,
    503 (5th Cir. 1967).
    IV. DISCUSSION
    We consider in turn MBUSI’s written solicitation and distribution rule, the
    distribution of union literature in MBUSI’s team centers, and the distribution of
    union literature in the MBUSI atrium.
    A. MBUSI’s Written Solicitation and Distribution Rule
    A rule explicitly restricting protected activity is per se unlawful. Martin
    Luther Mem’l Home, Inc., 
    343 N.L.R.B. 646
    , 646 (2004). An ambiguous or
    overbroad rule that employees would reasonably understand to prohibit protected
    3
    In Bonner v. City of Pritchard, 
    661 F.2d 1206
    , 1209 (11th Cir. 1981) (en banc), this
    Court adopted as binding precedent all decisions of the former Fifth Circuit handed down prior
    to close of business on September 30, 1981.
    12
    Case: 15-10291       Date Filed: 10/03/2016      Page: 13 of 55
    activity, on the other hand, is presumptively unlawful. Our 
    Way, 268 N.L.R.B. at 395
    n.6. If a rule is presumptively unlawful, the employer can rebut the
    presumption with evidence showing that the rule “was communicated or applied in
    such a way as to convey an intent clearly to permit” the protected activity. 
    Id. (quoting Essex
    Int’l, Inc., 
    211 N.L.R.B. 749
    , 750 (1974)) (emphasis in original);
    accord United Servs. Auto. Ass’n v. NLRB, 
    387 F.3d 908
    , 915 (D.C. Cir. 2004);
    NLRB v. Aluminum Casting & Eng’g Co., 
    230 F.3d 286
    , 293 (7th Cir. 2000);
    Motor Inn of Perrysburg, Inc. v. NLRB, 
    647 F.2d 692
    , 695 (6th Cir. 1981); Am.
    Safety Equip. Corp. v. NLRB, 
    643 F.2d 693
    , 696 (10th Cir. 1981); Birmingham
    Ornamental Iron Co. v. NLRB, 
    615 F.2d 661
    , 667 (5th Cir. 1980).
    When an employer attempts to rebut the presumption of unlawfulness with
    extrinsic evidence of either communication or application, the ALJ and the Board
    ask whether the evidence shows that the employer “convey[ed] an intent clearly to
    permit” the protected activity. Essex 
    Int’l, 211 N.L.R.B. at 750
    . If so, the
    overbroad rule does not represent a violation of the Act.4 Before considering the
    Order, we review Board and circuit court cases applying this fact-based analysis.
    4
    Contrary to the General Counsel’s suggestion, the Essex rule permits an employer to
    rebut the presumption of invalidity that attaches to any overbroad solicitation or distribution
    workplace rule. See United Servs. Auto. 
    Ass’n, 387 F.3d at 914
    (applying Essex rule where
    company banned solicitation and distribution “at any time in the work area and only during non-
    working hours in non-work areas”); Aluminum Casting & Eng’g 
    Co., 230 F.3d at 293
    (applying
    Essex rule where company banned solicitation “on company premises except when all concerned
    are relieved from duty”); Birmingham Ornamental Iron 
    Co., 615 F.2d at 667
    (applying Essex
    rule where company banned “ any soliciting on company premises and time”); Shaw, Inc., 350

    1. Cases applying the Essex rule
    a. Cases finding rebuttal
    In Standard Motor Products, in an effort to rebut the presumption of
    unlawfulness, an employer offered evidence of both clarifying communication and
    application. 
    265 N.L.R.B. 482
    , 483–84 (1982). The plant manager testified
    without contradiction “that it was his practice in going over [the employer’s] rules
    with new employees to tell them that breaks were their own time and they could do
    what they wanted during breaks and lunch periods.” 
    Id. at 484.
    The manager also
    testified “that the rule was not applied or enforced against any kind of union talk,”
    and the ALJ found that “there was no evidence in the record . . . to establish that
    any employee was under the impression that he could not engage in union activity
    during the lunch periods or breaktime.” 
    Id. Even a
    witness called by the General
    Counsel “testified that ‘everybody’ understood that breaks were their own free
    time.” 
    Id. The ALJ
    found, therefore, that the employer had rebutted the
    presumption of invalidity “by properly orally clarifying to employees the extent of
    application of the rule.” 
    Id. The Board
    affirmed the ALJ’s decision. 
    Id. at 482.
    N.L.R.B. 354, 377 (2007) (applying Essex rule where company banned solicitation during
    working time and “distribution of literature on company property at any time”); Laidlaw Transit,
    Inc., 
    315 N.L.R.B. 79
    , 82 (1994) (applying Essex rule where company banned solicitation and
    distribution “on company property, on company time”); Ichikoh Mfg., Inc., 
    312 N.L.R.B. 1022
    ,
    1022 (1993) (applying Essex rule where company banned solicitation and distribution of
    literature “on company premises or during company business hours”).
    14
    Case: 15-10291     Date Filed: 10/03/2016    Page: 15 of 55
    In The Broadway, the ALJ considered Standard Motor Products to stand for
    the proposition that an employer could rebut the presumption upon showing that it
    had clarified the rule “either through oral communication, or in such a manner as to
    convey an intent to permit [lawful] solicitation.” The Broadway, 
    267 N.L.R.B. 385
    , 403 (1983). Although the employer maintained an overbroad solicitation rule,
    the ALJ found that “employees were permitted to engage in a wide range of
    organizing activities in the employee lounge and canteen during their break and
    lunch periods with full knowledge of [the employer] and without interference.” 
    Id. The ALJ
    believed that “the uniform practice of applying the rule governing
    solicitation and distribution of literature in a manner fully consonant with
    [employees’ Section 7 rights] constitutes a fully efficacious clarification of the
    rule.” 
    Id. at 403–404.
    The ALJ reasoned that “[t]he objective interpretation
    accorded the scope and limitation of [the employer’s] rule by employees directly
    affected by it are more likely to be influenced by empirical experiences under the
    literal application of the rule, than by oral assurances.” 
    Id. at 404.
    The ALJ
    therefore concluded that the employer had rebutted the presumption. 
    Id. at 403.
    The Board affirmed the ALJ’s decision. 
    Id. at 385.
    In American Safety Equipment Corp., the Tenth Circuit considered the
    propriety of the Board’s having set aside a union election due to the employer’s
    overbroad solicitation and distribution 
    rule. 643 F.2d at 695
    . The court held that
    15
    Case: 15-10291       Date Filed: 10/03/2016      Page: 16 of 55
    the Board “erroneously applied” the Essex rule. 
    Id. at 696.
    Specifically, the court
    noted the uncontradicted affidavits of one manager and two employees. The
    manager averred that employees were informed of and were otherwise well aware
    that the rules applied only to working time. The manager and the two employees
    all agreed that employees openly distributed union material during nonworking
    time without repercussion. 
    Id. The court
    noted that the employer’s evidence of
    clarifying written or verbal communication was limited but set aside the Board’s
    order because “the evidence [was] uncontroverted that the rules were applied by
    [the employer] to permit proper Union solicitation.” 
    Id. The employer
    had
    rebutted the presumption with uncontradicted evidence that it “applied the rules
    lawfully, and that the employees understood [the rules] to permit [protected
    activity].” 
    Id. at 697.
    In Motor Inn of Perrysburg, the Sixth Circuit considered a violation
    regarding overly broad solicitation and distribution 
    rules. 647 F.2d at 695
    . The
    court noted the ALJ’s finding that the rules were never enforced, the lack of
    evidence that employees were chilled in exercising their Section 7 rights, and that
    “the evidence shows that the employees exercised these rights freely, openly, and
    frequently.” 
    Id. The court
    concluded, therefore, that “mere enactment of the
    overly broad rules was not a violation of the Act.” 5 
    Id. 5 This
    quote would be questionable if taken out of context. See Lafayette Park Hotel, 326

    b. Cases finding no rebuttal
    In Chicago Magnesium Castings Co., the ALJ found that an employer’s
    ambiguous rule was a violation “even though it appears from evidence in the
    record discussed herein, that [the rule] has not been consistently enforced.” 
    240 N.L.R.B. 400
    , 404 (1979). The ALJ held that the rule “was not cured by [the
    employer’s clarifying letter] since this letter was not posted, but was simply
    handed to [one employee] alone.” 
    Id. The employer
    ’s “publication of its
    disclaimer was inadequate for the purpose of absolving it from liability for a
    violation of the Act.” 
    Id. The Board
    affirmed the ALJ’s decision. 
    Id. at 400.
    In Ichikoh Manufacturing, the Board disagreed with the ALJ’s application of
    The Broadway and found that the employer had failed to rebut the presumption.
    Ichikoh 
    Mfg., 312 N.L.R.B. at 1022
    . The Board noted the ALJ’s “brief analysis” in
    which the ALJ found dispositive the employer’s evidence that some employees
    “have been permitted to solicit fellow employees and distribute campaign materials
    to employees during their lunch and rest breaks in non-working areas.” 
    Id. The Board
    paraphrased the ALJ’s reasoning to be “that the maintenance of a
    presumptively invalid no-solicitation rule is not violative of the Act, absent
    evidence that the rule ha[s] been enforced in an unlawful way.” 
    Id. The Board
    N.L.R.B. 824, 825 (“Where the rules are likely to have a chilling effect on Section 7 rights, the
    Board may conclude that their maintenance is an unfair labor practice, even absent evidence of
    enforcement.”). In Motor Inn of Perrysburg, however, the ALJ made findings that suggested
    open and knowing 
    non-enforcement. 647 F.2d at 695
    ; see also infra, note 7.
    17
    Case: 15-10291        Date Filed: 10/03/2016       Page: 18 of 55
    rejected the ALJ’s reasoning and conclusion because there was no evidence that
    the employer “clearly communicated” any clarification and because “[t]he fact that
    some employees ignored the rule and were not disciplined fails to meet [the
    employer’s] burden of establishing that it conveyed to employees ‘an intent clearly
    to permit solicitation during breaktime or other periods when employees are not
    actively at work.’” 
    Id. (quoting Our
    Way, 268 N.L.R.B. at 395 
    n.6).6
    In Laidlaw Transit, an employer argued that it “overcame the presumption
    of invalidity” attached to its overbroad solicitation and distribution policy “by
    communicating to its employees that the policy permitted [protected 
    activity].” 315 N.L.R.B. at 82
    . The ALJ wrote that “[c]larifications of ambiguous rules or
    narrowing interpretations of overly broad rules must be effectively communicated
    to an employer’s work force before the Board will conclude that the impact of
    facially illegal rules has been eliminated.” 
    Id. at 83.
    The ALJ found no evidence
    of the employer’s clarification and instead credited an employee’s testimony that
    “no one in management ever explained to [the employee] what the meaning of the
    rule was.” 
    Id. Thus, although
    the employer argued that it had clarified the rule by
    communication, the employer failed to meet its evidentiary burden on rebuttal. See
    
    id. The Board
    affirmed the ALJ’s decision. 
    Id. at 79.
    6
    The Board also mentions in a footnote that The Broadway does not support the ALJ’s
    broad proposition because “[i]n that case, no exceptions were filed concerning the [ALJ’s]
    finding that [the employer] had rebutted the presumptive invalidity of the no-solicitation rule.”
    Ichikoh 
    Mfg., 312 N.L.R.B. at 1022
    n.5.
    18
    Case: 15-10291    Date Filed: 10/03/2016    Page: 19 of 55
    In Shaw, the ALJ rejected an attempt by several employers to rebut the
    presumption that their overly broad distribution rule was a violation of Section 
    8. 350 N.L.R.B. at 377
    . The ALJ found the employers’ sparse evidence to be
    insufficient and listed showings the employers failed to make, such as “fail[ing] to
    adduce any evidence that [the employers] told employees that distribution during
    nonworking time was permitted [and failing to] show that [they] knowingly
    tolerated distribution by employees during nonworking time.” 
    Id. The ALJ
    therefore held that the employers “failed to show that the rule means anything
    other than what it says, viz., all distribution on company property at any time is
    prohibited.” 
    Id. The Board
    affirmed the ALJ’s decision as to this violation. See
    
    id. at 358.
    In Aluminum Casting & Engineering Co., the Seventh Circuit considered
    whether an employer had rebutted the presumption of invalidity by posting a
    lawful rule in its 
    cafeteria. 230 F.3d at 293
    . Noting that “the rule posted in the
    cafeteria made no reference to the [presumptively invalid rule], nor did it tell
    employees which rule took precedence,” the court reasoned that “[c]onscientious
    employees who had read both [rules] would not have known what was or was not
    permitted.” 
    Id. Therefore, the
    employer had failed to adequately rebut the
    presumption. 
    Id. at 294.
    c. Summary
    19
    Case: 15-10291      Date Filed: 10/03/2016       Page: 20 of 55
    The cases applying Essex indicate that, to clearly convey an intent to permit
    protected activity, an employer’s communication must be broadly disseminated
    and authoritative. See Aluminum Casting & 
    Eng’g, 230 F.3d at 293
    ; Laidlaw
    
    Transit, 315 N.L.R.B. at 83
    ; Standard Motor 
    Prods., 265 N.L.R.B. at 48
    ; Chicago
    Magnesium 
    Castings, 240 N.L.R.B. at 404
    . To clearly convey an intent to permit
    protected activity with evidence of a clarifying application, the employers’
    evidence should demonstrate that the employer openly and knowingly permitted
    employees to engage in the protected activity notwithstanding the available
    overbroad interpretation of the work rule. See Motor Inn of 
    Perrysburg, 647 F.2d at 695
    ; Am. Safety 
    Equip., 643 F.2d at 696
    ; 
    Shaw, 350 N.L.R.B. at 377
    ; Ichikoh
    Mfg., 
    312 N.L.R.B. 1022
    ; The 
    Broadway, 267 N.L.R.B. at 403
    –404. Without open
    permission of protected activity, the employer’s clarification may not have reached
    all employees. Without knowledge of the protected activity, an employer cannot
    be said to have conveyed its intent to permit the activity.
    Having attempted to articulate the line between sufficient and insufficient
    evidence that an employer clearly conveyed an intent to permit protected activity,
    we consider how (and whether) the Essex rule was applied in this case.7
    7
    The General Counsel attempts to cast doubt upon the Essex rule by discussing a series
    of cases holding that “mere maintenance” of an overbroad rule is a violation. See Martin Luther
    Mem’l 
    Home, 343 N.L.R.B. at 646
    ; Lafayette Park 
    Hotel, 326 N.L.R.B. at 825
    . But neither case
    expressly overrules Essex or Our Way, and neither case considers rebuttal of the presumption.
    Rather, the “mere maintenance” cases support the proposition that the General Counsel need not
    present evidence of enforcement to establish a prima facie case. See Beverly Health & Rehab.

    Case: 15-10291       Date Filed: 10/03/2016       Page: 21 of 55
    2. The ALJ’s application of the Essex rule
    In the instant case, the ALJ correctly identified the Martin Luther Memorial
    Home framework and found that MBUSI’s rule prohibiting “solicitation and/or
    distribution of non-work related materials . . . during work time or in work areas”
    did not explicitly prohibit protected activity but could reasonably be read to
    prohibit solicitation in work areas notwithstanding the fact that the employees may
    not be on working time. The presumption of unlawfulness therefore arose. The
    ALJ next considered MBUSI’s proffered rebuttal evidence and found that MBUSI
    “generally allowed employees to discuss the union in the workplace” and “truly
    sought to be neutral” towards the UAW.
    The ALJ next considered whether these findings rebutted the presumption of
    unlawfulness. First, the ALJ acknowledged that “an employer can cure an
    ambiguity in a work rule by communicating further with employees” and that
    “[MBUSI’s] defense may extend beyond the argument that it did not enforce the
    rule in its handbook.” Although the ALJ agreed with MBUSI that its non-
    enforcement “would contribute to how employees reasonably would understand
    Servs., Inc., 
    332 N.L.R.B. 347
    , 349 (2000) (citing Our Way for the proposition that “mere
    maintenance” raises the presumption). It also bears mentioning that the absence of evidence of
    enforcement differs significantly from affirmative evidence “that the employees exercised [their]
    rights freely, openly, and frequently,” Motor Inn of 
    Perrysburg, 647 F.2d at 695
    , or that the
    employer engaged in “the uniform practice of applying the rule . . . in a manner fully consonant
    with [employees’ Section 7 rights],” The 
    Broadway, 267 N.L.R.B. at 403
    –404. Thus, we are
    unpersuaded that the Essex rule no longer applies.
    21
    Case: 15-10291        Date Filed: 10/03/2016       Page: 22 of 55
    [the rule’s] meaning,” the ALJ expressed skepticism that MBUSI’s evidence
    showed that it had clearly conveyed to its employees an intent to permit solicitation
    in work areas by employees not on working time. The ALJ believed that MBUSI’s
    employees would continue to rely on the written rule “for a definitive answer” and
    concluded that MBUSI therefore violated the Act by maintaining an overbroad
    solicitation rule.
    We see no reversible error in the ALJ’s analysis. MBUSI showed that it
    generally permitted protected solicitation, but that is not necessarily enough. See
    Ichikoh 
    Mfg., 312 N.L.R.B. at 1022
    (“The fact that some employees ignored the
    rule and were not disciplined fails to meet [the employer’s] burden of establishing
    that it conveyed to employees an intent clearly to permit [protected solicitation].”).
    MBUSI bore the burden on rebuttal to prove that it applied the rule “in such a way
    as to convey an intent clearly to permit” protected solicitation. Essex 
    Int’l, 211 N.L.R.B. at 750
    . The ALJ did not believe that MBUSI clearly conveyed to
    employees its intent to permit protected solicitation, and the ALJ’s finding is
    supported by substantial evidence. We therefore enforce the Order and deny
    MBUSI’s petition for review as to this issue. 8
    B. Distribution of Union Literature in MBUSI Team Centers
    8
    The specific portions affected are as follows: paragraphs 1(a), 2(a), and 2(b) and the
    first, fourth, and fifth “We Will Not” paragraphs in the Appendix to the Order.
    22
    Case: 15-10291       Date Filed: 10/03/2016      Page: 23 of 55
    While the Act requires an employer to permit distribution of literature by
    employees on non-working time in non-work areas, an employer may prohibit
    distribution at any time in work areas. See Stoddard-Quirk 
    Mfg., 138 N.L.R.B. at 621
    . If special circumstances necessitate a more restrictive rule to maintain
    production and discipline, however, an employer may lawfully impose such a rule.
    
    Id. at 617
    n.4, 620.
    When deciding whether an area is a work area as contemplated by Stoddard-
    Quirk, “the Board has looked at the quality and quantity of work, which occurs in
    the area at issue, and examines whether the work is more than de minimus [sic]
    and whether it involves production.” Brockton 
    Hosp., 333 N.L.R.B. at 1375
    ; see
    also Patio Foods v. NLRB, 
    415 F.2d 1001
    , 1003 (5th Cir. 1969) (holding that a
    loading area was a work area notwithstanding the fact that employees used it for
    ingress and egress because “[t]he loading of trucks is no less a vital part of the
    production process because it is performed outside the plant building”). More
    recently, the Board has deemed certain areas to be mixed-use areas, in which
    distribution must be permitted. See, e.g., Transcon Lines, 
    235 N.L.R.B. 1163
    ,
    1165 (1978) enforced in relevant part, 
    599 F.2d 719
    (5th Cir. 1979).
    Mixed-use areas have been found in lunchrooms, 9 hallways, 10 parking lots,11
    and driver assembly and waiting areas.12 At oral argument, the General Counsel
    9
    Kaynard ex rel. NLRB v. Palby Lingerie, Inc., 
    625 F.2d 1047
    , 1052 n.6 (2d Cir. 1980);
    23
    Case: 15-10291       Date Filed: 10/03/2016       Page: 24 of 55
    suggested the Board has never established a test to determine whether an area is
    mixed use. Certainly though, the numerous Board and circuit court cases finding a
    mixed-use area or reviewing a mixed-use finding can inform us as to the
    appropriate analysis.
    1. A review of cases involving mixed-use areas
    The “mixed-use area” moniker developed out of two different situations:
    (1) a converted mixed-use area, which is a work area that periodically
    accommodates non-work (or a mix of both work and non-work) for a fixed
    duration;13 and (2) a permanent mixed-use area, which is an area that is perpetually

    used for both work and non-work activities. 14 An employer may never prohibit
    distribution of literature in a permanent mixed-use area but may prohibit
    distribution in a converted mixed-use area when the area is being used as a work-
    area. At oral argument, the General Counsel urged the Court to consider this a
    permanent mixed-use area case. MBUSI, however, contends that this is a
    conversion case and that its policy permitting distribution when the production line
    is stopped is therefore lawful. Based upon our review of conversion cases and
    permanent mixed-use area cases below, we conclude that mixed-use analysis is
    highly fact-intensive and often requires consideration of both conversion and
    permanent mixed-use cases.
    a. Conversion cases
    The earliest conversion case, Rockingham Sleepwear, does not use the term
    “mixed-use area” at all. See generally 
    188 N.L.R.B. 698
    . Rather, the case
    identifies a specific period during which a work area “is not a ‘work area’ . . . but a
    lunchroom where distribution may not lawfully be prohibited.” 
    Id. at 701.
    Rockingham Sleepwear involved a garment manufacturer that threatened to fire an
    be mixed-use area “during… the prestart period”); Ford Motor

    employee who had distributed literature in the manufacturer’s sewing room. 
    Id. at 699.
    The manufacturer had no cafeteria or other facility where employees could
    eat. 
    Id. Instead, the
    manufacturer would halt all production and permit employees
    to eat in the sewing room. 
    Id. The trial
    examiner, with the Board’s affirmance,
    held that the sewing room was therefore not a work area during the lunch period.
    
    Id. at 701.
    By restricting distribution of union literature by employees on their
    lunch break in a converted lunchroom, the manufacturer had violated Section 8.
    See 
    id. A few
    years later, in Oak Apparel, the Board considered a similar 
    situation. 218 N.L.R.B. at 701
    . The employer, an apparel manufacturer, had prohibited
    several employees who had placed union “leaflets on machines in [the employer’s]
    production area during the employees’ 45-minute lunch break.” 
    Id. As in
    Rockingham Sleepwear, the employer had no designated lunch area and permitted
    employees to eat lunch at their machines. 
    Id. Unlike Rockingham
    Sleepwear,
    “some employees (paid on a piece rate basis) continued to work at their machines
    during the lunch period.” 
    Id. The ALJ
    declined to find a violation but failed to
    clearly state a reason. See 
    id. at 709.
    Citing Rockingham Sleepwear, the Board
    reversed the ALJ and found a violation because “[i]t [wa]s sufficiently clear from
    the . . . record that the work area was being used principally as a lunchroom at the
    time that the distribution of union literature was attempted.” 
    Id. at 701–702.

    Years later, in Ford Motor Co., the Board affirmed an ALJ’s application of
    Oak Apparel to a case involving an employer’s automobile engine test 
    facility. 315 N.L.R.B. at 609
    –610, 612. The facility had four wings, each of which
    contained several enclosed testing cells. 
    Id. at 611.
    “Between every two cells was
    a ‘control room’ with an interior glass window to permit the employee-technicians
    seated at consoles adjacent to the window, to see into the cell and monitor the
    tests.” 
    Id. In the
    center of the control room was a table that employees frequently
    used for lunch. 
    Id. There was
    a separate cafeteria in the facility, but it was not
    always open. 
    Id. An employee
    was stopped by supervisors while distributing
    union material during his lunch break to other employees who were both on their
    lunch break and sitting at the center table. 
    Id. The ALJ
    disagreed with the
    employer’s contention that “the control rooms remained worksites regardless of
    their periodic use as luncheon areas.” 
    Id. at 612.
    The ALJ quoted the Board’s
    finding in Oak Apparel that “the work area was being used principally as a
    lunchroom at the time” and therefore held that the employer had violated the Act.
    
    Id. The Second
    Circuit considered the conversion issue in Kaynard ex rel.
    NLRB v. Palby Lingerie, 
    Inc., 625 F.2d at 1052
    n.6. Citing Oak Apparel and
    Rockingham Sleepwear, the court described the rule as follows:
    Where, as here, a production area is regularly used by employees as a
    lunch area with the “full knowledge and approval” of the employer,
    27
    Case: 15-10291      Date Filed: 10/03/2016    Page: 28 of 55
    the Board’s position is that the area ceases, for the duration of the
    lunch period, to be a “work area” where distribution can be
    prohibited.
    
    Id. Finding the
    rule to be reasonable, the Second Circuit affirmed a Board order
    finding that the employer had violated the Act when it fired an employee for
    repeatedly distributing union material in the production area during lunch breaks.
    
    Id. at 1051,
    1052 n.6.
    The Sixth Circuit has also considered a conversion case, United Parcel
    Service, Inc. v. NLRB, in which the employer had disciplined an employee-driver
    for distributing a union newspaper in a check-in area, “where drivers congregate
    before [their work day 
    starts].” 228 F.3d at 775
    . The ALJ held that this “prestart
    period” was “the only time during the day that drivers assemble together off the
    clock.” United Parcel Serv., Inc., 
    325 N.L.R.B. 1
    , 4 (1997). In the check-in area,
    drivers were “free to talk, read newspapers and magazines, or stand around until
    their assigned starting time.” 
    Id. Although the
    employer offered evidence of work
    activities that took place in the check-in area at other times, the ALJ found that
    “during the prestart period itself . . . the package drivers are not on the clock and
    they do not perform work.” 
    Id. at 5.
    Likewise, evidence that “a supervisor
    [would] occasionally give some instructions or supplies to a driver during the
    prestart period,” was “the exception and not the rule.” 
    Id. The ALJ
    therefore held
    that the check-in areas were non-work or mixed-use areas during the prestart
    28
    Case: 15-10291     Date Filed: 10/03/2016   Page: 29 of 55
    period. 
    Id. The Board
    agreed, stating “concerns for protecting the production
    process . . . do not rise to the same level when an employer compromises a work
    area by permitting nonwork use of it.” United Parcel Serv., Inc., 
    327 N.L.R.B. 317
    , 317 (1998).
    On petition for review, the Sixth Circuit affirmed and enforced the Board’s
    order. United Parcel Serv., 
    Inc., 228 F.3d at 782
    . Citing Rockingham Sleepwear,
    Oak Apparel, and Transcon Lines, the court described a mixed-use area as follows:
    “while some people may use the area for work, most of the employees use it for
    non-work purposes—such as a lunch area or a break 
    area.” 228 F.3d at 776
    . The
    court held that the ALJ’s findings of fact supported the mixed-use characterization
    and distinguished several work-area cases as “deal[ing] with areas still retaining
    the characteristics of a work area but where non-working employees happened to
    be found, not areas transformed into lounge or break areas during certain times of
    the day.” 
    Id. at 777.
    b. Permanent mixed-use area cases
    In Transcon Lines, the Board challenged an interstate freight handling,
    hauling, and storage company’s conduct in censuring an employee who distributed
    material critical of the local union in the “drivers’ room” of the company 
    terminal. 235 N.L.R.B. at 1164
    . The drivers’ room was open 24 hours per day to
    accommodate the company’s around-the-clock operation. 
    Id. Upon two
    hours’
    29
    Case: 15-10291     Date Filed: 10/03/2016   Page: 30 of 55
    notice of a trip, a driver would go to the terminal, punch the timeclock in the
    drivers’ room, pick up and complete necessary trip documents, and read any
    company notices and bulletins. 
    Id. A driver
    might also wait in the drivers’ room
    for his or her companion driver. After a trip, a driver would complete travel
    documents and other reports and may wait in the drivers’ room for transportation
    home. 
    Id. “While in
    the drivers’ room, the employees may drink coffee or eat
    snacks from machines provided therein, and may converse freely with other
    drivers.” 
    Id. Some drivers
    would go to the drivers’ room to speak with other
    drivers, but the room was not commonly used for loitering. 
    Id. The drivers’
    room had two bulletin boards. 
    Id. One belonged
    to the union,
    and the other contained miscellaneous items such as solicitations and religious
    material. 
    Id. Although drivers
    were not paid for their time in the drivers’ room,
    their mileage pay accounted for the fact that drivers must complete certain
    paperwork for each trip. 
    Id. at 1165.
    There was no other location at the
    company’s terminal where drivers could congregate, meet, and exchange
    information. 
    Id. The Board
    adopted the ALJ’s proposed order, which rejected for several
    reasons the company’s assertion that it lawfully prohibited distribution in the
    drivers’ room. 
    Id. First, the
    company had no non-discriminatory solicitation and
    distribution rule. Rather, the company permitted union distribution and
    30
    Case: 15-10291     Date Filed: 10/03/2016   Page: 31 of 55
    miscellaneous non-protected distribution in the drivers’ room. 
    Id. Second, to
    the
    extent one could determine a rule, the company’s rule was impermissibly vague.
    
    Id. Third, “the
    drivers’ room is, at best, a mixed use area, where drivers may either
    work or relax.” 
    Id. Fourth, the
    drivers’ room “is also the only area where drivers
    can regularly communicate with one another on subjects of mutual concern.” 
    Id. The Board
    therefore found that the company had impermissibly prohibited
    protected distribution in violation of the Act. On appeal, the Fifth Circuit affirmed
    the Board’s finding regarding the drivers’ room but remanded the case upon
    concluding that the remedy was overbroad relative to the ALJ’s factual inquiry and
    findings. Transcon 
    Lines, 599 F.2d at 721
    , 722.
    In Superior Emerald Park Landfill, the Board affirmed the ALJ’s finding
    that an employer unlawfully prohibited distribution of union literature in a
    company 
    lunchroom. 340 N.L.R.B. at 449
    , 457. During a union representative
    campaign, an employee had placed union literature on a table in the lunchroom,
    which was also used for occasional meetings. 
    Id. at 453,
    457. The employer used
    the lunchroom tables for distribution of information to employees, and witnesses
    testified to occasional employee use for things such as Girl Scout cookie sign-up
    sheets and other noncompany activities. 
    Id. at 453–54.
    Citing United Parcel
    Service and Rockingham Sleepwear, the ALJ stated “if an area is used for
    production during most of the day, but serves as a lunchroom during the lunch
    31
    Case: 15-10291       Date Filed: 10/03/2016     Page: 32 of 55
    period, distribution of literature may not be prohibited.” 
    Id. at 456.
    The ALJ then
    noted that the occasional meetings in the lunchroom were “relatively infrequent
    and there is no doubt that the primary purpose of the room was as a lunch facility.”
    
    Id. at 457.
    Therefore, the employer unlawfully prohibited distribution of union
    literature in its lunchroom, a mixed-use area. 
    Id. In Foundation
    Coal West, a two-member panel of the Board 15 affirmed the
    ALJ’s finding that a coal mining company violated the Act by calling a sheriff to
    remove off-duty employees who were distributing union literature in the
    company’s 
    hallway. 352 N.L.R.B. at 147
    –49. In the hallway, one could find “the
    timeclock, . . . a bench where employees congregate to socialize and eat their lunch
    opposite the coffeemaker and microwave, various bulletin boards, three vending
    machines, an ice machine, . . . desks[,] and cabinets for first aid supplies, forms,
    medicine, and ear plugs.” 
    Id. at 148
    (footnotes omitted). At the beginning of each
    shift, the employees would meet in a room off the hallway for a short pre-shift
    meeting. 
    Id. “Occasionally the
    dispatcher will tell an employee of an assignment
    change in the hallway if they cannot contact the employee in the [room off the
    hallway].” 
    Id. at 148
    –49. Some employees, blasters and drillers, would speak
    with each other or their supervisors in the hallway during shift change. 
    Id. at 149.
           15
    The Supreme Court later determined in a different case that a two-member panel may
    not exercise the Board’s delegated authority. See New Process Steel, L.P. v. NLRB, 
    560 U.S. 674
    , 
    130 S. Ct. 2635
    (2010). The ALJ’s analysis, in which two Board members concurred, is
    nevertheless informative. See DHL Express, Inc. v. NLRB, 
    813 F.3d 365
    , 377 n.2 (D.C. Cir.
    2016).
    32
    Case: 15-10291      Date Filed: 10/03/2016   Page: 33 of 55
    The time within which these work discussions would take place in the hallway was
    minimal, “as little as 15 minutes out of a 12-hour workday.” 
    Id. After briefly
    discussing Transcon Lines and United Parcel Service, the ALJ
    found significant the fact that the employer’s “main function is the digging,
    removal, sorting, and distribution of coal.” 
    Id. at 150.
    According to the ALJ, “[i]t
    is the main production areas of an employer’s facility where the hazards of littering
    and maintaining order are paramount over employee distribution of literature.” 
    Id. Although the
    re was “no doubt that some work incidental to [the employer’s] main
    function takes place in the [h]allway,” the hallway was at best a mixed-use area,
    “where both socializing and nonproduction work, incidental to [the employer’s]
    main function, the production of coal, take place.” 
    Id. Therefore, the
    employer
    had violated the Act. In its brief affirmance, the two-member panel stated “we
    agree that the hallway at issue was a mixed use area in which extensive nonwork
    activities, such as dining and socializing, occurred and that, consequently, under
    extant Board precedent, [the employer] was not free to ban distribution of union
    literature in the hallway.” 
    Id. at 147
    n.1.
    Recently, the D.C. Circuit considered the Board’s standards for mixed-use
    areas. See DHL Express, Inc. v. NLRB, 
    813 F.3d 365
    (D.C. Cir. 2016). In DHL
    Express, an international shipping company on several occasions interrupted an
    employee trying to distribute union literature in a hallway in the company’s United
    33
    Case: 15-10291     Date Filed: 10/03/2016   Page: 34 of 55
    States hub facility. DHL Express, Inc., 
    357 N.L.R.B. 1742
    , 1743 (2011). The
    employer argued that its hallway was a work area because (1) employees traverse
    the hallway on their way to and from work and during the infrequent times when
    they must assist with a task in the company’s ramp area, (2) on a less than daily
    basis, quality control personnel carry misplaced or damaged packages through the
    hallway for two or three minutes each trip, and (3) on a less than daily basis, the
    employer brings new employees or other visitors in the hallway for five to ten
    minutes for a tour. 
    Id. at 1744.
    The evidence indicated that the employer had on
    several occasions permitted non-work solicitation and distribution activity in the
    hallway such as gymnasium membership solicitation and distribution of t-shirts
    hats, and raffle tickets in conjunction with major sporting events. 
    Id. at 1745.
    The
    ALJ found that “the hallway area is used for recreation as well as some work but
    [the employer] compromised the hallway area by permitting nonwork use of it.”
    
    Id. Therefore, the
    employer had violated the Act.
    The Board affirmed but disagreed on the basis for affirmance. 
    Id. at 1742.
    Two members based their affirmance on the employer’s interference with
    distribution in a mixed-use area, stating that “an employer’s right to preclude
    distribution of literature in working areas does not extend to mixed-use areas.” 
    Id. at 1742
    n.1. One member believed that “the hallway could reasonably be
    considered a working area even if all activity within that area did not involve
    34
    Case: 15-10291    Date Filed: 10/03/2016    Page: 35 of 55
    employees performing work.” 
    Id. That member
    would have affirmed on the
    ALJ’s alternate finding that the employer discriminated against union activity in its
    enforcement of the no-distribution rule. 
    Id. The D.C.
    Circuit enforced the Board’s order and discussed at length the
    employer’s challenge to the ALJ’s mixed-use finding. See DHL 
    Express, 813 F.3d at 375
    –78. According to the court, “[t]he Board has for decades—with court
    approval—found areas in which minimal or solely incidental work is conducted are
    to be considered ‘mixed-use’ areas in which a prohibition on distribution during
    non-work time has to be justified by special circumstances.” 
    Id. at 375
    (citing
    United Parcel Serv., 
    327 N.L.R.B. 317
    ; Transcon 
    Lines, 235 N.L.R.B. at 1165
    ;
    Rockingham 
    Sleepwear, 188 N.L.R.B. at 701
    ). The employer argued the ALJ
    improperly broadened the test for a mixed-use area when he stated that the hallway
    was not used “exclusively” for work, but the court disagreed, stating “a miniscule
    amount of nonwork will not now convert a work area into a ‘mixed use’ area.” 
    Id. at 376.
    Rather, a mixed-use area is one in which “very little work occurs.” 
    Id. The court
    agreed with the analysis in Foundation Coal West and considered it
    persuasive that only incidental, nonproduction work took place in the hallway. 
    Id. at 377–78.
    Therefore, the court found substantial evidence supporting the ALJ’s
    mixed-use-area finding and enforced the Board’s order. 
    Id. at 378,
    380.
    c. Summary of the mixed-use area cases
    35
    Case: 15-10291     Date Filed: 10/03/2016    Page: 36 of 55
    The mixed-use area cases reflect the variance typical of a fact-intensive
    analysis. The core considerations for both conversion and permanent mixed-use
    areas are (1) the volume of work and non-work activity; (2) whether the non-work
    activity is limited to specific time periods; and (3) the nature of work and non-
    work activity. Cf. DHL 
    Express, 813 F.3d at 376
    (“[T]he ALJ carefully considered
    the type, duration, and frequency of work and nonwork occurring in the hallway
    prior to concluding that it should be considered a ‘mixed-use’ area.”); United
    Parcel 
    Serv., 228 F.3d at 776
    ; 
    Kaynard, 625 F.2d at 1052
    n.6.
    2. The ALJ’s findings and the Order
    The ALJ found that the team centers are mixed-use areas and that MBUSI
    therefore interfered with protected activity in violation of the Act when it
    reprimanded Gilbert for distributing union literature in his team center in the
    minutes before shift change. In deciding the team centers are mixed-use areas, the
    ALJ noted that the team centers have refrigerators, microwave ovens, and picnic
    tables in the same general area as filing cabinets, desks, and computers. The ALJ
    also gave weight to the fact that employees use the team centers for lunch, citing
    Superior Emerald Park 
    Landfill, 340 N.L.R.B. at 456
    (“[I]f an area is used for
    production during most of the day, but serves as a lunchroom during the lunch
    period, distribution of literature may not be prohibited.”). The ALJ considered
    MBUSI’s argument regarding the proximity of team centers to the production line
    36
    Case: 15-10291     Date Filed: 10/03/2016   Page: 37 of 55
    and the logistics line as an argument not that team centers are work areas but that
    MBUSI is entitled to an exception due to special circumstances. The ALJ declined
    to rule on special circumstances as to the other 18 team centers but found that
    MBUSI failed to demonstrate special circumstances as to Gilbert’s team center.
    The Board affirmed. One member of the Board noted separately that he
    considered it unnecessary for the Board to determine the status of any team center
    other than the one in which the June 20, 2013 incident occurred. Among other
    remedies, the Board ordered MBUSI to cease and desist from prohibiting
    employees not on working time from distributing literature in mixed-use areas,
    which the Board defined to include all of MBUSI’s team centers.
    3. The Board’s errors
    We conclude the Board’s affirmance was error for two reasons. First, the
    ALJ failed to recognize the distinction between converted and permanent mixed-
    use areas and failed to analyze the relative volume and nature of work and non-
    work activity in the team centers. Second, the ALJ imposed a remedy that
    exceeded the scope of his factual inquiry and findings. We therefore decline to
    enforce the Order as to this violation and remand to the Board with instructions as
    stated below.
    a. The inadequately supported mixed-use area finding
    37
    Case: 15-10291     Date Filed: 10/03/2016     Page: 38 of 55
    Team centers are walled or chained areas within the production area of
    MBUSI’s plant. MBUSI uses the team centers daily in its production process as
    offices for Group Leaders and Team Leaders, as observation posts for engineers
    and quality personnel, and as the marshalling place for pre-production meetings.
    At least 15 of the 19 team centers are immediately adjacent to the production line,
    and all of the team centers are adjacent to the logistics aisle, an indoor path used by
    forklifts and other motorized vehicles to transport parts in the assembly area. The
    work that takes place in the team centers could hardly be described as “non-
    production” or “incidental” to MBUSI’s main function, manufacturing
    automobiles. On the other hand, the General Counsel properly notes that
    employees often gather in the team centers for an indeterminate period before the
    pre-production meeting and use the team center during shift and meal breaks.
    During this time, employees may take advantage of the refrigerators, microwave,
    and picnic tables that can be found in the team centers.
    The ALJ reasoned that “[t]he fact that the team centers serve as meeting and
    eating places for off-the-clock employees taking lunch or break time and also as
    offices for [MBUSI] clearly weighs in favor of finding the centers to be mixed use
    areas.” The ALJ therefore held that “the team centers, which employees use to eat
    lunch while on nonworking time, properly are classified as mixed use areas.” In
    support of its conclusion, the ALJ quotes Superior Emerald Park Landfill, which
    38
    Case: 15-10291       Date Filed: 10/03/2016        Page: 39 of 55
    observed that “if an area is used for production during most of the day, but serves
    as a lunchroom during the lunch period, distribution of literature may not be
    
    prohibited.” 340 N.L.R.B. at 456
    (citing United Parcel Serv., 
    327 N.L.R.B. 317
    ).
    Although the ALJ relied exclusively upon non-work use during lunch and break
    periods, the Order does not limit the mixed-use finding to any specific period of
    time. This was error.
    Some language in Superior Emerald Park Landfill appears to suggest that if
    a production area is used for lunch, distribution must be perpetually allowed in the
    area. 
    See 340 N.L.R.B. at 456
    . In fact, when a production area is converted to
    non-work use for a discrete period (such as lunch), the conversion cases hold that
    distribution may not be prohibited during the non-work period. See United Parcel
    
    Serv., 327 N.L.R.B. at 318
    (affirming and adopting an order that required the
    employer to cease and desist enforcing its no distribution rule “prior to the starting
    time of the package 
    drivers,” 325 N.L.R.B. at 12
    (emphasis added)); Rockingham
    
    Sleepwear, 188 N.L.R.B. at 701
    (“[I]n effect, the sewing room, for the duration of
    the lunch period, is not a ‘work area’ . . . but a lunchroom where distribution may
    not be lawfully prohibited.” (emphasis added)).16 This is the essence of the
    distinction between converted mixed-use areas and permanent mixed-use areas.
    16
    We attribute Superior Emerald Park Landfill’s incomplete statement of the holding in
    conversion cases to the fact that Superior Emerald Park Landfill is not a conversion case at all.
    In Superior Emerald Park Landfill, the room was used for “occasional meetings,” but “the
    39
    Case: 15-10291       Date Filed: 10/03/2016       Page: 40 of 55
    The ALJ’s analysis, affirmed by the Board without comment, does not
    support the conclusion that the team centers are permanent mixed-use areas. The
    only non-work use to which the ALJ refers occurs during the lunch period and
    scheduled breaks. This evidences conversion, not perpetual mixed use.
    The ALJ’s analysis cannot support a permanent mixed-use finding for a
    second reason: the ALJ failed to “carefully consider[] the type, duration, and
    frequency of work and nonwork occurring in the [team centers] prior to concluding
    that [they] should be considered [] ‘mixed-use’ area[s].” See DHL 
    Express, 813 F.3d at 376
    . The ALJ made no finding regarding the relative volume of work and
    non-work that takes place in the team centers or regarding the number of
    employees who use the team centers for each. See 
    id. at 375–77;
    United Parcel
    
    Serv., 228 F.3d at 776
    . Nor did the ALJ consider whether the work that takes place
    in the team centers is essential or merely incidental to production. See DHL
    
    Express, 813 F.3d at 375
    –77. As discussed above, the ALJ did not find that team
    centers are perpetually used for both work and non-work activities. Thus, the
    ALJ’s analysis fails to support a conclusion that the team centers are permanent
    mixed-use areas.
    primary purpose of the room was as a lunch 
    facility.” 340 N.L.R.B. at 457
    . That is a far cry
    from “an area [that] is used for production during most of the day.” 
    Id. at 456.
    Thus, Superior
    Emerald Park Landfill does not support broadening the remedy in converted mixed-use cases.
    40
    Case: 15-10291     Date Filed: 10/03/2016    Page: 41 of 55
    Although we find that the ALJ misapplied the mixed-use test to conclude
    that the team centers are permanent mixed-use areas, we note that the Order may
    be supportable in a narrowed form. As discussed above, if an employer
    temporarily converts a work area to non-work or mixed-use, the employer may not
    prohibit distribution of literature among employees on non-working time. See
    United Parcel 
    Serv., 325 N.L.R.B. at 4
    , 5. The ALJ’s mixed-use analysis was
    fixated upon the lunch period and scheduled breaks (periods during which MBUSI
    already permits distribution), but the ALJ’s findings of fact include references to a
    third time period. In the several minutes before a shift change, off-the-clock
    employees gather in the team centers in anticipation of their shift. During that
    same period, supervisors in the team centers prepare for a pre-shift meeting. It is
    during this period that the alleged violation underlying this issue took place.
    We believe that Board precedent may have supported a conclusion that the
    team centers are converted mixed-use areas during the pre-shift period. The ALJ
    did not analyze the effect of the pre-shift period on the work status of the team
    centers, however, and we may not adopt alternate grounds to enforce a Board
    order. See First Nat. Maint. 
    Corp., 452 U.S. at 672
    n.6, 101 S. Ct. at 2577
    
    (“Because the court adopted different grounds for enforcement of the Board’s
    order, it was error to enforce without a remand to the Board for further
    examination of the evidence and proper factfinding.”). We therefore decline to
    41
    Case: 15-10291       Date Filed: 10/03/2016       Page: 42 of 55
    enforce the Order17 but remand for the Board to consider whether the evidence and
    its precedent support the narrower finding that MBUSI’s team centers are
    converted mixed-use areas during the pre-shift period.
    b. The overbroad remedy
    Even if we agreed with the Board’s mixed-use finding, we would be
    compelled to deny enforcement of the Order as written because it imposes a
    remedy that exceeds the scope of its factual findings by a factor of 19. In
    compliance with Stoddard-Quirk Manufacturing, after concluding that all 19 team
    centers are mixed-use areas, the ALJ considered whether special circumstances
    justified MBUSI’s prohibition on distribution of literature in team centers when the
    production line is moving.
    Before the ALJ, MBUSI offered testimony regarding the pace of its just-in-
    time production process, the proximity of team centers to the production line and
    the logistics aisle, the dangers associated with vehicular traffic in the logistics
    aisle, and MBUSI’s safety concerns regarding distribution of literature. The ALJ
    noted the persuasiveness of some of MBUSI’s testimony, stating as follows:
    The team center depicted in [MBUSI’s offered] video was so close to
    the production line and so proximate to the hustle and bustle of the
    assembly process it produced an intuitive feeling that this busy place
    certainly must be a work area, even if there is a picnic table for
    workers to use on breaks and at lunch. At the least, it created the
    17
    The specific portions affected are as follows: the last four words of paragraph 1(b) and
    the words “team centers and” in the Appendix to the Order.
    42
    Case: 15-10291     Date Filed: 10/03/2016    Page: 43 of 55
    impression that unique circumstances warranted an exception to the
    general rule that an employer could not prohibit distribution of union
    literature in a mixed use area.
    (emphasis added). The ALJ noted the significant differences among the 19 team
    centers, however, and concluded that “it would not be appropriate to generalize
    from the video.” The ALJ concluded that MBUSI failed to meet its burden of
    showing special circumstances as to the team center where Gilbert was distributing
    union literature, “which is the only team center relevant to the allegations.”
    Therefore, the ALJ reasoned, “I need not, and do not, decide whether special
    circumstances existed at any other team center, such as the one depicted in the
    video.”
    Although only one team center was relevant to the inquiry and the ALJ
    explicitly declined to consider whether MBUSI met its burden of proving special
    circumstances at any of the other 18 team centers, the Order requires MBUSI to
    cease and desist from distributing literature in “its team centers.” Nothing in the
    Order limits its scope to the sole team center that the ALJ considered. Rather, even
    though MBUSI’s evidence “created the impression that unique circumstances
    warranted an exception to the general rule” at least as to one team center, the Order
    uniformly applies to all team centers. This was error.
    As the former Fifth Circuit noted in Transcon Lines, when the Board
    “narrow[s] the case for decision purposes,” it may not then “broaden it to the
    43
    Case: 15-10291     Date Filed: 10/03/2016     Page: 44 of 55
    widest possible limits for purposes of 
    remedy.” 599 F.2d at 722
    . Because the ALJ
    and the Board declined to consider MBUSI’s evidence of special circumstances as
    to the 18 team centers not at issue, the Order cannot impose a remedy as to those
    team centers. Therefore, on remand, absent additional factfinding regarding
    special circumstances at the other team centers, the Board may consider a violation
    and a remedy only as to the team center at which Gilbert attempted to distribute
    union literature.
    C. Distribution of Union Literature in the MBUSI Atrium
    Before the ALJ, MBUSI contended that any interference with Section 7
    rights was de minimis because within hours of stopping Garner and Gilbert’s
    handbilling MBUSI retracted its position prohibiting distribution in the atrium.
    Alternatively, MBUSI argued that its atrium is a work area where it can lawfully
    prohibit distribution. The ALJ found that MBUSI’s atrium was at most a mixed-
    use area and that MBUSI therefore violated the Act by prohibiting Garner and
    Gilbert from distributing union literature in the atrium during their non-work time.
    The ALJ agreed that MBUSI’s interference was de minimis but nevertheless
    recommended the Board find a violation because “[MBUSI’s] continued position
    that the atrium is a work area leaves open the possibility that it might decide to
    reverse its distribution policy sometime in the future.”
    44
    Case: 15-10291     Date Filed: 10/03/2016     Page: 45 of 55
    MBUSI filed 22 exceptions to the ALJ’s decision and recommended order,
    none of which identified the ALJ’s finding the atrium to be a mixed-use area. In
    fact, MBUSI expressly disavowed its previous argument that the atrium was a
    work area, stating that it wished to “remov[e] that issue from consideration.”
    Instead, MBUSI insisted that any interference with protected activity was de
    minimis and not a sufficient basis for a violation. The Board disagreed and
    affirmed the ALJ as to both the mixed-use finding and the violation.
    Before this Court, MBUSI contends the Board erred in concluding that the
    MBUSI atrium is a mixed-use area.18 We need not address this possible error,
    however, because MBUSI waived the issue by failing to raise it before the Board.
    Section 10 of the Act precludes judicial review of an error not first raised
    before the Board absent extraordinary circumstances. 29 U.S.C. § 160(e). We find
    nothing extraordinary in the circumstances that led MBUSI to make the tactical
    decision to focus its argument before the Board on the de minimis issue. We also
    find nothing extraordinary in the fact that the Board would not have entertained a
    motion for reconsideration on the mixed-use issue for the same reason we do not
    consider the issue: waiver. With nothing to review, we summarily enforce the
    Order as to this violation.
    18
    With Court approval, MBUSI withdrew from consideration its de minimis argument.

    Case: 15-10291    Date Filed: 10/03/2016   Page: 46 of 55
    V. CONCLUSION
    For the foregoing reasons, we enforce the Order with the exception of the
    last four words of paragraph 1(b) and the words “team centers and” in the
    Appendix. We remand to the Board with instructions to consider whether
    MBUSI’s team centers are converted mixed-use areas during the pre-shift period.
    If so, the Board should either narrow the scope of the Order to Gilbert’s team
    center or conduct additional factfinding regarding special circumstances at the 18
    team centers the ALJ did not consider.
    Enforced in Part, Enforcement Denied in Part, and Remanded in Part
    with Instructions.

    MARTIN, Circuit Judge, dissenting in part:
    I agree with the Majority’s ruling about the atrium violation and Mercedes-
    Benz’s solicitation and distribution policy. I also agree with the Majority that the
    ALJ’s remedial order regarding the team centers was overbroad. The order should
    be remanded to the Board to either narrow its scope or do more factual
    development about special circumstances at the eighteen team centers for which
    the ALJ did not make findings.
    However, I do not agree with the Majority’s holding that “the ALJ failed to
    recognize the distinction between converted and permanent mixed-use areas and
    failed to analyze the relative volume and nature of work and non-work activity in
    the team centers.” The Board does not impose this distinction on its factfinders,
    and I believe it exceeds our institutional role to create these categories and require
    the Board to apply them.
    The ALJ and the Board followed the Board’s precedent in designating the
    team centers as mixed-use areas after finding and reviewing the facts. I would
    affirm the Board’s ruling that the team center where Mr. Gilbert distributed union
    materials is a mixed-use area. I respectfully dissent.
    I.
    We apply a narrow and deferential standard of review to Board decisions.

    “[T]he findings of the Board with respect to questions of fact if supported by
    substantial evidence on the record considered as a whole shall . . . be conclusive.”
    29 U.S.C. § 160(f). “So long as the Board has made a plausible inference from the
    record evidence, we will not overturn its determinations, even if we would have
    made different findings upon a de novo review of the evidence.” Cooper/T. Smith,
    Inc. v. NLRB, 
    177 F.3d 1259
    , 1261 (11th Cir. 1999); see also NLRB v. McClain of
    Ga., Inc., 
    138 F.3d 1418
    , 1424–25 (11th Cir. 1998) (“Our standard of review is
    limited . . . to determining whether the Board’s inference . . . is supported by
    substantial evidence—not whether it is possible to draw the opposite inference.”).
    We also defer to the Board’s expertise in developing rules that create legal
    presumptions. See Republic Aviation Corp. v. NLRB, 
    324 U.S. 793
    , 798, 
    65 S. Ct. 982
    , 985 (1945) (The National Labor Relations Act “left to the Board the work of
    applying the Act’s general prohibitory language in the light of the infinite
    combinations of events which might be charged as violative of its terms. Thus a
    ‘rigid scheme of remedies’ is avoided and administrative flexibility within
    appropriate statutory limitations obtained to accomplish the dominant purpose of
    the legislation.”); Beth Israel Hosp. v. NLRB, 
    437 U.S. 483
    , 492, 
    98 S. Ct. 2463
    ,
    2469 (1978) (“The effect of [the Board’s] rules is to make particular restrictions on
    employee solicitation and distribution presumptively lawful or unlawful . . . .”).
    For example the distribution of union materials in nonworking areas is
    48
    Case: 15-10291      Date Filed: 10/03/2016     Page: 49 of 55
    presumptively lawful. See Stoddard-Quirk Mfg. Co., 
    138 N.L.R.B. 615
    , 621
    (1962). Congress gave the Board authority to use its national labor relations policy
    expertise to formulate rules that balance conflicting legitimate interests such as
    employee-organization rights and employer-property rights. Beth Israel 
    Hosp., 437 U.S. at 492
    , 500–01, 98 S. Ct at 2469, 2473. Thus, “[t]he rule which the
    Board adopts is judicially reviewable for consistency with the Act, and for
    rationality, but if it satisfies those criteria, the Board’s application of the rule, if
    supported by substantial evidence on the record as a whole, must be enforced.” 
    Id. at 501,
    98 S. Ct at 2473–74. Instead of reviewing the Board’s rules, the majority
    creates its own rule and faults the ALJ for not applying it.
    II.
    The Majority’s opinion presents the distinction between “permanent” and
    “converted” mixed-use areas as a framework established by the Board. Indeed, the
    Majority cites “45 years of Board precedent” to support its distinction. But I read
    none of the cases it cites to state a rule creating or even distinguishing between two
    types of mixed-use categories. It is beyond our deferential role to create a rule and
    then hold that the ALJ erred in failing to apply it. See NLRB v. Curtin Matheson
    Sci., Inc., 
    494 U.S. 775
    , 786, 
    110 S. Ct. 1542
    , 1549 (1990) (“[T]he NLRB has the
    primary responsibility for developing and applying national labor policy.”).
    49
    Case: 15-10291     Date Filed: 10/03/2016    Page: 50 of 55
    The Majority recognizes that the Board has never clearly established a test
    for deciding whether an area is mixed-use. And it is the Board that has the
    expertise to establish a test if it decides one is necessary. The Board can also
    choose to grant its ALJs flexibility in crafting solutions for a circumstance that is
    unique. See Beth Israel 
    Hosp., 437 U.S. at 500
    –01, 98 S. Ct at 2473 (“[I]t is to the
    Board that Congress entrusted the task of ‘applying the Act’s general prohibitory
    language in the light of the infinite combinations of events which might be charged
    as violative of its terms.’” (quoting Republic 
    Aviation, 324 U.S. at 798
    , 65 S. Ct. at
    985)). What matters here is that the Board has extended this flexibility to ALJs
    charged with making mixed-use determinations.
    The Board’s allowance of flexibility to ALJs in designating mixed-use areas
    results in some variations in that designation. For example, in Transcon Lines, 
    235 N.L.R.B. 1163
    (1978), the ALJ found generally that “the drivers’ room is, at best, a
    mixed use area, where drivers may either work or relax.” 
    Id. at 1165.
    But in In Re
    United Parcel Serv., 
    325 N.L.R.B. 1
    (1997), the ALJ ruled “that the check-in areas
    are used as nonwork or, at most, mixed use areas between 7:30 a.m. and the
    drivers’ start time of 8:30 a.m.,” thus limiting the area’s mixed-use status based on
    the time of day. 
    Id. at 3.
    The Majority chooses one understanding of the Board’s approach to these
    cases and makes it a new rule for how ALJs must analyze the facts of all cases
    50
    Case: 15-10291        Date Filed: 10/03/2016       Page: 51 of 55
    about distributing union materials. Under the Majority’s rule, an ALJ will now be
    required “to analyze the relative volume and nature of work and non-work
    activity” in a given area. If both work and nonwork activities “perpetually” 1 occur
    in an area, then the Majority allows the ALJ to find that it is a “permanent mixed-
    use area.” If the activities are not “perpetual,” then the Majority directs the ALJ to
    consider whether an area is “converted” to mixed-use during specific times of the
    day. The Majority’s requirements impose a framework of analysis on ALJs the
    Board has never adopted. Beyond that, the Majority’s requirement that ALJs
    consider time-limitations in “converted” mixed-use cases narrows the Board’s
    existing rule, which already limits distribution to nonworking time. See DHL
    Express, Inc., 
    357 N.L.R.B. 1742
    , 1743 (2011) (“The Board has long held that
    rules prohibiting distribution of literature are presumed valid unless they extend to
    activities during nonworking time and in nonworking areas.”) The Majority, while
    no doubt well intentioned, is doing the Board’s job for it.
    The Majority also cites the D.C. Circuit for support. That court said that
    “[t]he Board has for decades—with court approval—found areas in which minimal
    or solely incidental work is conducted are to be considered ‘mixed-use’ areas in
    which a prohibition on distribution during non-work time has to be justified by
    1
    The Majority does not explain this “perpetually” standard. Is it that an area can be used
    at all times for either work or nonwork activities or both? Or is it that an area is used for both
    types of activities at all times? What about 80% usage of a space for either? 50%? 33%?
    51

    special circumstances.” DHL Express, Inc. v. NLRB, 
    813 F.3d 365
    , 375 (D.C. Cir.
    2016) (citing United Parcel Serv., 
    327 N.L.R.B. 317
    (1998); Transcon 
    Lines, 235 N.L.R.B. at 1165
    ; Rockingham Sleepwear, 
    188 N.L.R.B. 698
    , 701 (1971)); see
    also United Parcel Serv., Inc. v. NLRB, 
    228 F.3d 772
    , 776 (6th Cir. 2000) (citing
    Transcon Lines and Rockingham to support a similar proposition). But two out of
    three of the citations the D.C. Circuit gave for this proposition are cases the
    Majority gives as examples of “converted mixed-use” (Rockingham and United
    Parcel Serv.) and the third is offered by the majority as a “permanent mixed-use”
    case (Transcon Lines). See DHL 
    Express, 813 F.3d at 375
    . This contrasting view
    of identical case law given by two Circuit courts is more evidence that the Majority
    created its own framework instead of deferring to the Board’s flexible approach. I
    do not understand the Board to have limited the definition of “mixed-use” to either
    of the categories imposed by the Majority. Rather, the Board has left room for the
    ALJs to designate mixed-use areas, or not, based on the various situations that
    come before them. See, e.g., Ford Motor Co., 
    315 N.L.R.B. 609
    , 612 (1994)
    (discussing specific employee activities at times of specific distribution incidents
    to determine whether there was a distribution violation); Transcon 
    Lines, 235 N.L.R.B. at 1164
    –65 (referring to several fixtures and functions of a drivers’ room
    in determining that it was “at best, a mixed use area, where drivers may either
    work or relax”); 
    Rockingham, 188 N.L.R.B. at 701
    (discussing plant schedule and
    52
    Case: 15-10291    Date Filed: 10/03/2016   Page: 53 of 55
    use of spaces at various times before determining when distribution must be
    allowed).
    III.
    I view the ALJ’s decision that the team center was a mixed-use area to be
    supported by substantial evidence. In Stoddard-Quirk, the Board held that
    employees can distribute union literature in nonworking areas on the employer’s
    
    premises. 138 N.L.R.B. at 621
    . In Transcon Lines, the Board extended that
    holding to mixed-use areas, meaning areas where employees “may either work or
    
    relax.” 235 N.L.R.B. at 1165
    . And the Board has reasoned that “[t]he concerns for
    protecting the production process which were at issue in Stoddard Quirk do not rise
    to the same level when an employer compromises a work area by permitting
    nonwork use of it.” United Parcel 
    Serv., 327 N.L.R.B. at 317
    ; accord DHL
    
    Express, 357 N.L.R.B. at 1744
    . Further, the Board has recognized that “[i]t is the
    main production areas of an employer’s facility where the hazards of littering and
    maintaining order are paramount over employee distribution of literature.” Found.
    Coal W., Inc., 
    352 N.L.R.B. 147
    , 150 (2008). However, aside from these broader
    observations, the Board also recognizes that special circumstances can call for
    more restrictive rules. See 
    Stoddard-Quirk, 138 N.L.R.B. at 617
    n.4, 620. These
    complex realities have led the Board to avoid establishing a more detailed test for
    53
    Case: 15-10291       Date Filed: 10/03/2016       Page: 54 of 55
    determining whether an area is mixed-use. I fear the Majority opinion puts this
    Court at cross-purposes with the Board in this way.
    This case requires only the simple application of our precedent in NLRB v.
    Transcon Lines, 
    599 F.2d 719
    (5th Cir. 1979).2 In that case we described “the
    drivers’ room as a place for lounging, recreation and waiting, as well as a place to
    receive dispatches and complete documents.” 
    Id. at 721–22.
    On that record, we
    upheld the Board’s finding that the room was a mixed-use area as “supported by
    substantial evidence.” 
    Id. at 721.
    This ALJ found that the team centers at issue here were mixed-use areas
    based on their use “as meeting and eating places for off-the clock employees taking
    lunch or break time and also as offices for [Mercedes-Benz] supervisors.” This
    finding was supported by the design of the team centers, which “resemble[d] an
    office in some respects and a breakroom in others.” The ALJ also considered
    special circumstances, finding that the evidence provided by Mercedes-Benz was
    not specific to the team center where Mr. Gilbert distributed union materials.
    Our job is to review this finding to see whether it is supported by substantial
    evidence in the record. This record shows the team centers are used for certain
    work functions, like pre-shift employee meetings. They contain a few desks and
    2
    In Bonner v. City of Prichard, 
    661 F.2d 1206
    (11th Cir. 1981) (en banc), we adopted as
    binding precedent all decisions of the former Fifth Circuit handed down before October 1, 1981.
    
    Id. at 1209.
                                                   54
    Case: 15-10291     Date Filed: 10/03/2016   Page: 55 of 55
    computers, and work-related items like attendance calendars and bulletin boards
    are fixed to the walls. But the team centers also have the trappings of a typical
    breakroom, like refrigerators and microwaves for employees to use during breaks
    and before shifts. The centers also contain several tables that employees use for
    eating, drinking, and relaxing during lunch and break periods. Like the drivers’
    room in Transcon Lines, the team centers are used for a combination of work and
    non-work functions. The ALJ’s designation of the team center as a mixed-use area
    was supported by substantial evidence.
    IV.
    Also, in my view, the Majority fails to properly credit the analysis in the
    ALJ’s order. The Majority opines that the ALJ erred because “the Order does not
    limit the mixed-use finding to any specific period of time.” To the contrary, the
    ALJ ordered Mercedes-Benz to “[c]ease and desist from . . . [p]rohibiting
    employees not on working time from distributing literature to other employees not
    on working time in a mixed use area.” This effectively limits the mixed-use status
    of the team centers to lunch periods, scheduled breaks, and pre-shift changes.
    While I don’t agree with the Majority’s invention of “converted mixed-use areas,”
    even accepting it, the ALJ’s order complies.
    I respectfully dissent.
