    OPINION
    PER CURIAM:
    The National Labor Relations Board (NLRB) petitions to enforce
    an order that it issued after proceedings held following a remand by
    this Court, in which the NLRB found that the Pepsi-Cola Bottling
    Company of Fayetteville, Inc. (Pepsi) violated §§ 8(a)(3) and (5) of
    the National Labor Relations Act, 
    29 U.S.C.A. § 158
     (West 1998)
    (the Act), by unilaterally changing various employment practices and
    policies. Because substantial evidence in the record indicates that
    each of the changes implemented by Pepsi represented material
    changes to the terms and conditions of employment, and further, that
    the United Food and Commercial Workers, Local 204, AFL-CIO-
    CLC (the Union) did not waive its right to bargain over these
    changes, we grant enforcement of the NLRB’s order.
    I.
    A.
    The NLRB has found that Pepsi violated the Act by unlawfully
    implementing a change to its moving violations policy, resulting in
    the discharge of two employees, by unlawfully changing its "zero set-
    tlement" policy, resulting in the discharge of one employee, by
    unlawfully changing other terms and conditions of employment, and
    by unlawfully withholding a wage increase from employees. Pepsi-
    Cola Bottling Co. of Fayetteville, 
    330 NLRB No. 134
     (2000) (herein-
    after NLRB II). In 1994, the NLRB made the same conclusions.
    Pepsi-Cola Bottling Co. of Fayetteville,

     (1994) (here-
    NLRB v. PEPSI-COLA                           3
    inafter NLRB I). It sought enforcement before this Court, which
    enforced the NLRB’s order in part, denied enforcement in part, and
    remanded to the NLRB for further development of the record on
    remaining issues. NLRB v. Pepsi-Cola Bottling Co. of Fayetteville,
    No. 95-1924, 
    1996 U.S. App. LEXIS 23936
     (4th Cir. Sep. 10, 1996)
    (unpublished) (hereinafter Pepsi I). This Court upheld the NLRB’s
    determination that two employees, Hyatt and Faas, were terminated
    based on anti-union animus in violation of § 8(a)(3) of the Act,
    reversed the NLRB’s determination that two employees, Deskin and
    Evers, were made to change tires and clean garage drains on the basis
    of anti-union animus, and remanded with respect to the issues now
    raised by this appeal. Id. at *22. Following this Court’s remand, two
    days of additional evidentiary hearings were held before an Adminis-
    trative Law Judge, whose findings that Pepsi violated the Act in each
    of the areas alleged were upheld by the NLRB. The NLRB now peti-
    tions for enforcement of its order.
    B.
    Pursuant to a petition filed by the Union, the NLRB ordered a rep-
    resentation election at Pepsi’s Fayetteville, N.C. plant, which was
    held on October 11, 1991. The preliminary result of the election
    showed 33 votes in favor of representation, 31 against, and 3 determi-
    native ballots challenged by the NLRB agent on the ground that the
    employees’ names did not appear on the voter eligibility list. After
    proceedings to resolve a challenge to these disputed ballots, the
    NLRB resolved the challenged ballots favorably to the Union on
    August 17, 1992, and on September 4, 1992, the Union was certified
    by the NLRB as the bargaining agent for the bargaining unit employ-
    ees at the Fayetteville plant. Thereafter, Pepsi took several actions
    which the NLRB held to constitute unfair labor practices in violation
    of the Act. We will examine the record regarding each of these
    actions in turn.
    1. The Annual Wage Increase
    First, the NLRB found that Pepsi illegally withheld a customary
    annual pay increase from the non-supervisory employees at the Fay-
    etteville plant, during the interval between the representation vote and
    the resolution of challenges to several determinative ballots. The evi-
    4                         NLRB v. PEPSI-COLA
    dence indicates that in or about August of each year, Pepsi’s corporate
    parent, Pepsi Bottling Ventures, LLC, estimates a cap on wage
    increases for the following year and gives this estimate to each of
    Pepsi’s facilities; in turn, these facilities have latitude to determine if,
    and how much, of a wage increase to give each individual employee,
    subject to the requirement that the total payroll increase for each facil-
    ity must be within the cap authorized by the corporate office. In 1992
    with the exception of the Fayetteville plant, each of Pepsi’s facilities
    provided a general, across-the-board pay increase for employees. At
    the Fayetteville facility in 1992, management decided to grant pay
    increases to all supervisory employees while withholding wage
    increases from all non-supervisory employees, that is, employees who
    would be in the Union bargaining unit if the Union won the election
    and was certified by the NLRB.
    David Schriber, a former route salesman for Pepsi at the Fayette-
    ville plant, testified at the remand hearing that he worked at the Fay-
    etteville plant from 1987 to 1993, and received a one cent per case
    cost of living increase in his commission every year except 1992.
    Schriber also testified that in February 1992 he attended a meeting
    where the subject of wage increases came up and that at this meeting,
    Fayetteville General Sales Manager Randall Kennedy stated that
    raises were delayed because Pepsi was waiting for the NLRB to
    resolve the ballot challenges and determine whether the Union had
    won the representation election. Thomas Leak, another former
    employee at the Fayetteville plant, testified that he worked for Pepsi
    from 1986 to 1997 and received an annual pay increase during every
    year except 1992. Kennedy testified that he did not have knowledge
    of the decision making process at the Fayetteville plant for wage
    increases prior to 1992, when he transferred to Fayetteville from the
    Lumberton plant, but that at the Lumberton plant it was customary to
    grant a general wage increase to all, or nearly all, employees within
    the wage increase parameters set by Pepsi headquarters each year.
    In Pepsi I, this Court remanded the wage increase issue to the
    NLRB for the NLRB to, inter alia, "identify the employees, if any,
    affected by the wage increase," explain possible inconsistencies in the
    NLRB’s position regarding the wage increase,1 develop additional
    1
    Pepsi argued below, but does not argue on appeal, that the NLRB has
    taken inconsistent positions regarding the discretionary nature of the
    NLRB v. PEPSI-COLA                             5
    evidence regarding whether the wage increase was discretionary in
    nature, and explain the effect of any compliance proceedings regard-
    ing the wage increase. Pepsi I, 
    1996 U.S. App. LEXIS 23936
    , at *14.
    In its decision, the NLRB determined that compliance proceedings
    would be a better device to determine the specific affected employees.
    NLRB II, 330 N.L.R.B. No. 134 at *3 n.10. The NLRB denied having
    adopted inconsistent positions regarding the wage increase and
    pointed to additional record evidence adduced on remand indicating
    that the wage increase was not discretionary. 
    Id. at *17
    .
    2. Zero Settlement
    On December 9, 1991, Pepsi announced a change in its zero settle-
    ment policy; this policy requires drivers to account for any discrep-
    ancy between payments received and the number of cases of soda
    missing from their trucks. Prior to the change, employees were
    required to account for their stock on a daily basis and pay any short-
    fall to Pepsi on a weekly basis. After the new policy, as a memoran-
    dum from Randall Kennedy explains, drivers were required to
    account for their stock on a daily basis and immediately pay any
    shortfall at the end of each business day. Both prior to and after the
    zero settlement policy, drivers were required to account for their stock
    each day; the difference was that before zero settlement, drivers had
    until the end of the week to locate and return any missing stock before
    being required to pay for the shortage, whereas after zero settlement,
    withheld 1992 wage increase. Apparently Pepsi was referring to the
    inconsistency allegedly created by the NLRB’s finding that the withheld
    1992 wage increase was customary vis a vis the Office of General Coun-
    sel’s 1993 refusal to pursue a claim that the similar 1993 wage increase
    was customary. Pepsi also could have been referring to the NLRB’s
    apparent doctrine that the Act is violated when an employer fails to grant
    a customary raise prior to the certification of a union, while the Act also
    may be violated when an employer grants a customary raise prior to cer-
    tification because the raise may be viewed as an impermissible attempt
    to "buy off" employees in order to cause them to vote against unioniza-
    tion. (See J.A. at 388-389); Perdue Farms, Inc. v. NLRB, 
    144 F.3d 830
    ,
    839 (D.C. Cir. 1998) (Randolph, J., dissenting in part) (describing as
    "unimaginable" the NLRB’s position that both the granting and with-
    holding of customary pre-election wage increases violate the Act).
    6                       NLRB v. PEPSI-COLA
    payment had to be made at the end of each day. Jerry Parker, whom
    the NLRB asserts was terminated based on the new zero settlement
    policy, paid his shortage on the day it occurred and was terminated
    a week later for failing to settle his account correctly.
    The undisputed record evidence indicates that the Union was not
    given formal notification of the zero settlement policy before it was
    implemented, but that at some point after the policy was announced,
    the Union’s representatives heard of the new policy from employees.
    The Union filed an unfair labor practice charge with the NLRB, but
    did not request bargaining over the new policy.
    3. Moving Violations/Accidents
    Pepsi has long had a policy providing that employees who drove
    company vehicles would be discharged if they committed too many
    moving violations or were involved in an excessive number of
    chargeable (i.e. at-fault) accidents within a given period of time. On
    January 14, 1993, Pepsi announced a change in its moving violations
    policy, the precise nature of which is not entirely clear from the
    record. The NLRB’s original decision held that the "new" policy was
    that "moving violations without convictions and accidents without
    fault" now counted against an employee. NLRB I, 315 NLRB at 897.
    Pepsi asserts that no record evidence demonstrates that the "new pol-
    icy" was actually new; the company contends that Pepsi’s policy had
    always been to count a citation against the moving violations limit,
    leaving the citation on the employee’s record unless and until the
    employee was fully acquitted. Thus, Pepsi asserts that the policy both
    before and after the "change" was that an employee who had, for
    example, two moving violation convictions or unacquitted citations
    would be immediately terminated upon receipt of his or her third cita-
    tion, without awaiting the result of court proceedings. Randall Ken-
    nedy testified that prior to the announcement of the "new" policy, he
    had informed employees eight to twelve times that citations counted
    for purposes of the moving violations policy even if the charges were
    later reduced. The Union was not notified prior to the implementation
    of the "new" moving violations policy.
    4. Compensation for Drivers and Salesmen
    In July 1992, Pepsi unilaterally changed the compensation system
    for bulk truck drivers, "tell-sell" (restaurant-focused) salesmen, and
    NLRB v. PEPSI-COLA                           7
    "full-service" (vending machine focused) salesmen. This change
    involved moving from a pure commission system to a system charac-
    terized by a lower commission and an hourly wage. One employee
    testified that the new system reduced his compensation. The Union
    was not notified in advance of this change.
    5. Changes in Starting Times and Work Schedules
    In July 1993, Pepsi changed the work schedules of merchandisers
    so that they were required to work nearly every Saturday, but received
    a day off during the week. At the same time, Pepsi changed the start-
    ing time for route salesmen from 6 A.M. to 5:45 A.M. The Union was
    not notified in advance of the announcement of these changes. When
    the Union learned of the changes, it wrote to Pepsi requesting bar-
    gaining, but to no avail. Pepsi, without prior notice to the Union, also
    changed the work schedules of sparemen so that they no longer per-
    formed work substituting for regular drivers.
    6. Break Periods and Telephone Privileges
    On May 12, 1992, Pepsi eliminated employees’ ability to make and
    receive personal telephone calls at work, changed break periods, and
    restricted the ability of employees to converse during lunch. The
    Union was not notified in advance of these changes.
    II.
    A.
    The NLRB’s interpretations of the Act are entitled to deference if
    they are reasonable, even if the NLRB’s reading of the Act is not "the
    best way to read the statute." Holly Farms Corp. v. NLRB, 
    517 U.S. 392
    , 409 (1996) (emphasis in original). "If the NLRB’s legal interpre-
    tations are rational and consistent with the Act, they will be upheld
    by reviewing courts." Sam’s Club v. NLRB, 
    173 F.3d 233
    , 239 (4th
    Cir. 1999) (internal quotation marks omitted). "When we review
    mixed questions [of fact and law], the NLRB’s application of legiti-
    mate legal interpretations to the facts of a particular case should be
    upheld if they are supported by substantial evidence based upon the
    8                          NLRB v. PEPSI-COLA
    record as a whole." 
    Id. at 239-40
    . Substantial evidence review must
    consider evidence which detracts from as well as supports the
    NLRB’s findings, and substantial evidence is "such relevant evidence
    as a reasonable mind might accept as adequate to support a conclu-
    sion." 
    Id.
     (internal quotation marks omitted). A reviewing court
    engaged in substantial evidence review may not "displace the
    NLRB’s choice between two fairly conflicting views" of the evi-
    dence, "even though the court would justifiably have made a different
    choice had the matter been before it de novo." Universal Camera
    Corp. v. NLRB, 
    340 U.S. 474
    , 488 (1951).
    B.
    Pepsi argues that because this Court decided in an earlier appeal
    that a remand was necessary to further develop the factual record
    regarding the materiality of the various changes to Pepsi’s policies,
    the NLRB is precluded from re-arguing the sufficiency of the prior
    record on appeal.
    Under the doctrine of law of the case,
    [w]hen a decision of an appellate court establishes the "law
    of the case," it must be followed in all subsequent proceed-
    ings in the same case in the trial court or on a later appeal
    . . . unless: (1) a subsequent trial produces substantially dif-
    ferent evidence, (2) controlling authority has since made a
    contrary decision of law applicable to the issue, or (3) the
    prior decision was clearly erroneous and would work mani-
    fest injustice.
    Sejman v. Warner-Lambert Co., 
    845 F.2d 66
    , 69 (4th Cir. 1988)
    (internal quotation marks omitted); see Plyler v. Evatt, 
    924 F.2d 1321
    ,
    1328 (4th Cir. 1991). The law of the case doctrine is "not an inexora-
    ble command but rather a prudent judicial response to the public pol-
    icy favoring an end to litigation." Sejman, 
    845 F.2d at 69
     (internal
    quotation marks omitted).
    Pepsi’s principal argument is that the NLRB is precluded from
    arguing the sufficiency of the pre-remand record to establish the
    NLRB v. PEPSI-COLA                           9
    materiality of Pepsi’s unilateral policy changes. Pepsi contends that
    because this Court directed the NLRB to address the materiality of the
    unilateral changes on remand, we have of necessity already deter-
    mined that the original record was legally insufficient to establish the
    materiality of the changes. Were materiality the only reason for our
    earlier remand, this logic would be compelling. The primary basis for
    this Court’s remand to the NLRB, however, was a lack of evidence
    regarding the issue of whether the Union received effective notice of
    the changes and thus waived its right to bargain over them. Pepsi I,
    
    1996 U.S. App. LEXIS 23936
    , at *20-22. Thus, our mention of the
    desirability of adducing additional materiality evidence on remand
    does not compel a conclusion that we found the existing materiality
    evidence to be legally insufficient; it means merely that, after decid-
    ing to remand the findings at issue on other grounds, we determined
    that additional materiality evidence would be helpful. Based upon our
    review of our prior opinion in this case, we conclude that the NLRB
    is precluded from re-arguing the sufficiency of the original record as
    to notice and waiver issues — the principal bases for our remand —
    but not as to materiality.
    III.
    A.
    This Court, in Pepsi I, stated that because the parties had not sub-
    mitted evidence that there was an established practice of awarding
    wage increases at the Fayetteville plant, "we cannot determine how
    established any practice of paying wage increases was, nor can we
    determine whether any discretion entered the calculus for disbursing
    the wage increase." Pepsi I, 
    1996 U.S. App. LEXIS 23936
     at *13 (4th
    Cir. Sep. 10, 1996). We noted that absent an anti-union motive, an
    employer may disburse or fail to disburse discretionary bonuses, but
    noted, however, that if a practice of paying bonuses is well-
    established, withholding such a bonus unilaterally may violate the
    Act. See 
    id. at *13-14
    ; Phelps Dodge Mining Co. v. NLRB, 
    22 F.3d 1493
    , 1496-1500 (10th Cir. 1994) (holding that where there was no
    established practice of distributing bonuses, employer was not
    required to bargain over their distribution). This Court, in Southern
    Maryland Hosp. Ctr v. NLRB, 
    801 F.2d 666
     (4th Cir. 1986), summa-
    rized the law in this area as follows:
    10                       NLRB v. PEPSI-COLA
    There is general agreement that when an employer by prom-
    ises or by a continuous course of conduct has made a partic-
    ular benefit part of the established wage or compensation
    system, then the withholding of that benefit during an orga-
    nizational campaign raises the inference of improper
    employer conduct. An employer can avoid the finding of a
    violation in such a case only if he can separately justify his
    action with a legitimate business purpose. On the other
    hand, when there is no "established practice" of granting
    benefits, the General Counsel must show that the employ-
    er’s withholding of particular benefits was motivated by
    anti-union sentiment to prove a violation of the Act.
    
    Id. at 668-69
     (internal citation omitted). We found that a one-time
    payment of a Christmas bonus the year before a union election did not
    suffice to establish a practice of paying such bonuses, so that the
    employer was not required to bargain before declining to pay the
    bonus again; further, we held that isolated anti-union comments made
    to a handful of employees did not suffice to demonstrate that the
    bonus was withheld based on anti-union animus. 
    Id. at 670-71
    . If a
    company has a longstanding practice of granting wage increases to
    keep up with the cost of living, a certain amount of discretion as to
    the amount of the wage increase does not prevent the regular wage
    increase from becoming a condition of employment and, thus, a sub-
    ject of mandatory bargaining. NLRB v. Beverly Enter.-Massachusetts,
    Inc., 
    174 F.3d 13
    , 25 (1st Cir. 1999).
    Pepsi argues that the NLRB, on remand, failed to develop suffi-
    cient evidence either that the wage increases at the Fayetteville plant
    occurred over a number of years or that Pepsi lacked discretion in
    determining whether to raise wages and if so, by what amount. The
    NLRB argues that evidence adduced at the remand hearing estab-
    lished that Pepsi budgeted annual wage increases for each of its thir-
    teen North Carolina plants; that on each of six occasions prior to
    1992, each North Carolina plant granted general wage increases to all,
    or nearly all, employees; that the Fayetteville plant was the only Pepsi
    facility in North Carolina to decline to grant a pay increase to bargain-
    ing unit employees in 1992; and that this decision was a distinct
    departure from the practice of management at the Fayetteville plant
    prior to 1992. The NLRB also notes that the Southern Maryland
    NLRB v. PEPSI-COLA                         11
    Court held that the withholding even of a discretionary benefit vio-
    lates the Act when motivated by specific anti-union animus, and here,
    the record shows that Pepsi told employees prior to the election that
    if they voted for the union, Pepsi would freeze wages. Moreover, in
    announcing that no wage increase would be given, Pepsi stated that
    the pendency of the NLRB proceedings to resolve the union election
    was the reason for its decision.
    We conclude that while the NLRB’s evidence at the remand hear-
    ing could have been more complete, its determination that Pepsi
    established over a number of years a regular pattern of granting gen-
    eral wage increases at the Fayetteville plant is supported by substan-
    tial evidence. David Schriber, who worked at the Fayetteville plant
    from 1987 to 1993, testified that Pepsi "normally" announced a one
    cent per case increase in driver commissions during November or
    December of each year (J.A. at 329), and the only year that this did
    not occur was 1992, when Kennedy announced to the delivery drivers
    that the wage increase was "waiting on the [NLRB] to make a deci-
    sion on the [election ballot challenge] case." (J.A. at 331.) Kennedy
    himself testified that during every year that he worked at the Lumber-
    ton plant, management implemented a broad-based wage increase
    based on the targets provided by Pepsi’s corporate headquarters. The
    NLRB could reasonably infer that practice was similar at the Fayette-
    ville plant, there being no evidence to the contrary and some evidence
    (Schriber’s testimony) supportive of this view. Thomas Leak, a sales-
    man at the Fayetteville plant from 1986 to 1997, stated that towards
    the end of every year of his tenure except 1992, the company held a
    meeting for all sales employees and announced a general pay
    increase.
    Pepsi argues that the NLRB has failed to carry its burden on this
    issue because it introduced no evidence of the process for setting pay
    increases at the Fayetteville plant. Pepsi misconceives the nature of
    the controlling legal standard. Some discretion as to the amount of the
    increase does not cause the increase to become discretionary in its
    entirety and thus, not a subject of mandatory bargaining. Substantial
    evidence was adduced at the remand hearing that Pepsi’s Fayetteville
    plant generally, during every year except 1992, granted wage
    increases in line with the cap set by corporate headquarters. The fail-
    ure to grant any wage increase at all in 1992 to the bargaining unit
    12                       NLRB v. PEPSI-COLA
    employees was obviously a change in Pepsi’s customary practice.
    This situation is utterly unlike the occasional, sporadic, indeed one-
    time, Christmas bonus at issue in Southern Maryland. See Southern
    Maryland, 
    801 F.2d at 668
    . Here, a reasonable finder of fact could
    conclude that Pepsi generally granted cost of living increases to bar-
    gaining unit employees from 1986 to 1991, did not do so in 1992
    immediately following the Union vote and while the results of the
    election were pending, and resumed doing so after 1992. Thus, annual
    wage increases were a condition of employment and could not be var-
    ied unilaterally by Pepsi during the pendency of the union election
    results. Further, if there were an evidentiary infirmity in the NLRB’s
    finding that pay increases were a customary practice, such an infir-
    mity would be irrelevant because Southern Maryland held that even
    a discretionary benefit may not be withheld out of anti-union animus.

    . Here, Pepsi’s statement before the representation election
    that it would freeze wages if the union won the election provides rea-
    sonably strong evidence that its freezing of wages after the union
    election — explicitly in order to see how the election would turn out
    after the ballot challenge — was motivated by such animus.
    We thus conclude that the NLRB adduced sufficient evidence on
    remand to establish that the withheld 1992 wage increase was custom-
    ary, and thus, Pepsi’s act of withholding it from the Fayetteville bar-
    gaining unit employees violated the Act.
    B.
    The NLRB found that Pepsi violated 
    29 U.S.C.A. § 158
    (a)(5) by
    unilaterally changing the method of compensation for bulk truck driv-
    ers, restaurant-focused ("tell-sell") salesmen, and vending machine
    ("full-service") salesman; changing telephone access, break period,
    and lunch period policies; and implementing the zero-settlement pol-
    icy, without providing advance notice to the Union. NLRB II, 330
    N.L.R.B. No. 134, at *22-23 (2000). An employer violates 
    29 U.S.C. § 158
    (a)(5) if it unilaterally amends terms or conditions of employ-
    ment if it has not bargained with the Union regarding the unilateral
    amendments. Oneita Knitting Mills, Inc. v. NLRB, 
    375 F.2d 385
    , 388
    (4th Cir. 1967). If the Union has notice of an employer’s unilateral
    amendments, but does not request bargaining, the Union waives the
    right to bargain. YHA, Inc. v. NLRB, 
    2 F.3d 168
    , 173-74 (6th Cir.
    NLRB v. PEPSI-COLA                          13
    1993); W.W. Grainger, Inc. v. NLRB, 
    860 F.2d 244
    , 248-49 (7th Cir.
    1988) (stating that "a union, which has notice of a proposed change
    which affects a mandatory bargaining subject, must make a timely
    request to bargain. Moreover, formal notice is not necessary as long
    as the union has actual notice. A union’s failure to assert its bargain-
    ing rights will result in a waiver of these rights." (internal citation
    omitted)). In Pepsi I, this Court stated that "[t]o demonstrate that the
    Union waived the right to bargain over the unilateral amendments,
    Pepsi must show the right to bargain was clearly and unmistakably
    relinquished." Pepsi I, 
    1996 U.S. App. LEXIS 23936
     at *20-21 (inter-
    nal quotation marks omitted). The ALJ observed on remand that this
    language appears to assign the burden of proof on this issue to Pepsi
    rather than the NLRB; Pepsi counters that this cannot be the case
    because the NLRB always bears the burden of proof of showing
    unfair labor practices. Pepsi is precluded from making this argument
    for the same reason that the NLRB is precluded from arguing that the
    prior record was sufficient as to notice and waiver: this Court’s prior
    opinion is the law of the case. Thus, Pepsi bears the burden of proof
    of showing that the Union clearly waived its right to bargain over var-
    ious unilateral policy changes; this approach comports with the ordi-
    nary rule that the burden of proving affirmative defenses to liability
    rests with the defendant.
    In Pepsi I, Pepsi asserted that the Union had notice of the new zero
    settlement policy, the moving violations policy, and other alleged pol-
    icy changes, and by failing to request bargaining, waived any objec-
    tions to these alleged changes. This Court stated that it could not
    properly evaluate this argument because Pepsi had not "provide[d]
    any particulars, such as the type of notice, how the notice was con-
    veyed, or the length of time the Union had to respond to the propos-
    al[s] to implement unilateral amendments." Pepsi I, 
    1996 U.S. App. LEXIS 23936
     at *21. On this issue, the NLRB did develop significant
    additional evidence on remand. The ALJ, in a finding adopted by the
    NLRB, credited the testimony of Union representative Shelda
    Upchurch, who testified that Pepsi provided no notice to the Union
    prior to announcing the changes to the employees and that she learned
    of the changes only by hearing of the announcement from employees.
    NLRB II, 330 N.L.R.B. No. 134 at *22.
    Pepsi argues that numerous Board and court decisions establish
    that formal notice to the Union is not necessary where the Union has
    14                        NLRB v. PEPSI-COLA
    actual notice of a proposed policy change; thus, Pepsi argues, the "no-
    tice" test is a practical one, and the Union’s actual knowledge of the
    changes, obtained through employees who contacted the Union,
    means that the Union’s failure to request bargaining amounts to a
    waiver. See Haddon Craftsmen, Inc., 
    300 NLRB 789
    , 790 (1990);
    Southern California Stationers, 
    162 NLRB 1517
    , 1543 (1967).
    Because certain of the policy changes — such as zero settlement —
    had not been formally implemented when announced, Pepsi argues
    that the evidence establishes that the Union did, in fact, have notice
    prior to implementation of the proposed changes.
    Pepsi is correct that indirect notice to a union may suffice to
    require the union to request bargaining at risk of waiving its bargain-
    ing rights. W.W. Grainger, 
    860 F.2d at 248
    . The difficulty with
    Pepsi’s argument is that the decisions on which it relies — in particu-
    lar, Haddon Craftsmen — have been limited by later decisions of the
    NLRB and the courts to situations in which the changed policy was
    not announced to employees as a fait accompli prior to the notifica-
    tion of the Union. See Roll & Hold Warehouse & Distr. Corp., 
    325 N.L.R.B. 41
    , 42 (1997) (distinguishing Haddon Craftsmen on the
    basis that in that case, "notice was given to union officials . . . before
    general notice was given to employees," and holding that "a union’s
    role in [the collective bargaining] process is totally undermined when
    it learns of the change incidentally upon notification to all employ-
    ees"), enforcement granted, 
    162 F.3d 513
    , 519 (7th Cir. 1998) (stat-
    ing, "we find . . . convincing the NLRB’s second reason for finding
    that no opportunity for reasonable negotiation existed here: that by
    presenting the plan directly to employees before notifying the Union,
    the Union’s negotiating role was seriously undermined. . . . When an
    employer first presents a policy to its employees without going
    through the Union, the Union’s role as the exclusive bargaining agent
    of the employees is undermined."). The current state of the law, there-
    fore, is that informal notice of proposed changes is sufficient, but the
    presentation as a fait accompli of a complete plan directly to employ-
    ees without any prior contact, formal or informal, with the Union does
    not create effective notice such that the Union’s failure to request bar-
    gaining creates a waiver. The deference given to the NLRB’s inter-
    pretations of the Act causes us to conclude that this interpretation of
    the Act is within the range of reasonable interpretations to which this
    Court must defer. See 
    id. at 520
     (deferring to the NLRB’s conclusion
    NLRB v. PEPSI-COLA                           15
    that a full-blown announcement of a new policy directly to employees
    prior to notifying the Union "harmed [the Union] enough to justify its
    failure to demand bargaining."). Thus, accepting the NLRB’s decision
    to credit Upchurch’s testimony that the Union received notice of the
    proposed changes only after they were announced generally to
    employees, we conclude that the Union did not waive its right to bar-
    gain over these changes by failing to request bargaining. As a result,
    if the changes were material alterations of the terms and conditions
    of employment, Pepsi’s unilateral imposition of the changes violated
    the Act.
    C.
    A duty to bargain over changes to wages, hours, or terms or condi-
    tions of employment arises only if these changes are "material, sub-
    stantial, and . . . significant one[s] affecting the terms and conditions
    of employment of bargaining unit employees." Angelica Healthcare
    & Serv. Group, 
    284 NLRB 844
    , 853 (1987) (internal quotation marks
    omitted). Pepsi argues that the zero-settlement policy, moving viola-
    tions policy, new compensation scheme for salesmen and drivers, and
    miscellaneous changes in telephone and breaks policy, work starting
    times, etc., were not material. Having concluded that the Union did
    not waive its right to bargain over the changes and that the NLRB is
    not precluded from arguing the sufficiency of the original record, we
    will address the materiality of each of the unilateral changes in turn.
    1. Zero Settlement
    The NLRB argues that the new zero settlement policy was a mate-
    rial change because (1) it substantially inconvenienced employees
    because if they were short on stock at the end of one day, they could
    not subsequently locate the missing stock and avoid having to person-
    ally pay for the shortage; and (2) salesman Jerry Parker was dis-
    charged for violating the new system, demonstrating its materiality.
    Union representative Sheila Upchurch testified to the inconvenience
    that the new zero settlement policy caused for drivers and route sales-
    men.
    Pepsi argues persuasively that Parker was not terminated as a result
    of the new aspects of zero settlement. The record indicates unmistak-
    16                        NLRB v. PEPSI-COLA
    ably that he was terminated for failing to settle his account to zero
    each day, which was required even under the old system, but was not
    terminated for failing to pay the shortfall on a daily, as opposed to
    weekly, basis, which was the only change to the policy; uncontro-
    verted evidence demonstrates that Parker paid for his shortage on the
    day it occurred and thus cannot possibly have been terminated for
    failing to do so. We thus conclude that Parker was not terminated as
    a result of the new policy, and the NLRB’s reliance on his termination
    as evidence of materiality was error.2
    Upchurch’s testimony that the zero settlement policy greatly incon-
    venienced drivers suffices to enable the NLRB to carry its materiality
    burden. Given the deference accorded the NLRB’s determination of
    what is a mandatory subject of bargaining, see Beverly Enter.-
    Massachusetts, 
    174 F.3d at 29
    , we conclude that the requirement that
    drivers and salesmen pay shortfalls on a daily, as opposed to a
    weekly, basis imposes substantial inconvenience and thus should be
    regarded as a material change in the terms and conditions of employ-
    ment. Requiring employees to pay shortfalls on a daily basis requires
    them to carry sufficient cash each day to pay any shortfall and pre-
    vents them from making up for a shortfall on one day with an overage
    during the same week, as, for example, when extra cases of product
    are inadvertently delivered to a customer but can be returned the fol-
    lowing day. We therefore uphold the NLRB’s finding that the unilat-
    eral imposition of the new zero settlement policy violated the Act.
    2. Telephone Access, Break Periods, and Lunch Periods
    The NLRB found, based upon substantial evidence, that Pepsi
    changed its break period policy to limit employees to two 15-minute
    2
    Because the NLRB’s order requiring Parker’s reinstatement rested on
    both a violation of § 8(a)(1) of the Act and the purported § 8(a)(5) viola-
    tion deriving from the zero settlement policy, and we have already
    affirmed the NLRB’s finding that Pepsi violated § 8(a)(1) in terminating
    Parker, see NLRB v. Pepsi-Cola Bottling Co. of Fayetteville, No. 95-
    1924, 
    1996 U.S. App. LEXIS 23936
    , at *22 (4th Cir. Sep. 10, 1996), our
    conclusion that Parker was not discharged for violating the zero-
    settlement policy is relevant only to the NLRB’s use of Parker’s dis-
    charge as evidence of the materiality of the new policy.
    NLRB v. PEPSI-COLA                         17
    break periods, placed new restrictions on conversations among
    employees during their lunch breaks, and changed its telephone use
    policy so that employees could use the company’s telephones for per-
    sonal calls only in emergencies. NLRB II, 
    330 NLRB No. 134
    , at *5.
    The NLRB has held in the past that telephone policies and lunch and
    break periods can constitute mandatory subjects of bargaining. See
    Advertiser’s Mfg. Co., 
    280 NLRB 1185
    , 1191 (1986) (stating that
    telephone use is a term or condition of employment and employee
    telephone privileges are a mandatory subject of bargaining), enforce-
    ment granted, 
    823 F.2d 1086
     (7th Cir. 1987); Garrison Valley Ctr.,
    Inc., 
    246 NLRB 700
    , 709 (1979) (lunch and break periods are a man-
    datory subject of bargaining). Given the NLRB’s longstanding posi-
    tion that telephone, lunch, and break policies are mandatory subjects
    of bargaining, we find that substantial evidence supports the NLRB’s
    conclusion that Pepsi’s changes to these policies effected impermissi-
    ble, unilateral, and material changes to the terms and conditions of
    employment.
    3. Method of Compensation for Salesmen and Drivers
    The NLRB concluded that because § 8(d) of the Act, 
    29 U.S.C.A. § 158
    (d), requires employers to bargain with a collective-bargaining
    representative regarding, specifically, "wages," Pepsi’s move from a
    pure commission system to a system involving a lower commission
    plus an hourly wage, which reduced the pay of some employees (J.A.
    at 8-11), was the very paradigm of a forbidden unilateral change
    under the Act. Given § 8(d)’s specific mention of "wages" as a man-
    datory bargaining subject and the evidence indicating that Pepsi’s
    new policy reduced the wages of at least some employees, it is clear
    that the NLRB correctly found the new compensation system for
    salesmen and drivers to be an impermissible unilateral change in
    wages.
    4. Sparemen’s Work Schedule
    In November 1992, Pepsi changed the work schedule for sparemen
    so that they no longer were responsible for filling in for drivers. The
    NLRB reasoned that § 8(d) requires employers to bargain regarding,
    specifically, "hours." In the past, the NLRB has held that even a rela-
    tively small change in working hours is a mandatory subject of bar-
    18                       NLRB v. PEPSI-COLA
    gaining under the Act. Hedison Mfg. Co., 
    260 NLRB 590
    , 592-94
    (1982) (holding that a five-minute change in employee starting time
    is a mandatory subject of bargaining). In light of the well-established
    principle that working hours are a mandatory subject of bargaining,
    we cannot conclude that the NLRB erred in finding that Pepsi’s
    changes to the sparemen’s work schedules constituted an impermissi-
    ble unilateral change in violation of 
    29 U.S.C. § 158
    (a)(5). Similarly,
    the NLRB’s finding that Pepsi violated § 158(a)(5) by unilaterally
    changing the work schedules of merchandisers and route salesmen is
    supported by substantial evidence.
    5. Moving Violations Policy
    Pepsi argues that no record evidence establishes that the prior mov-
    ing violations policy was different from the "new" policy, in that cita-
    tions were always counted against the policy’s limits unless and until
    an employee was entirely acquitted. Evidence in the record, however,
    indicates that Pepsi’s prior policy applied only to "convictions"
    whereas under the new policy, citations counted against an employ-
    ee’s record unless and until an employee was acquitted. Further, the
    record also indicates that the new policy played a role in justifying the
    discharge of three employees, Hyatt, Lee, and Curtis. The record is
    not entirely clear as to the precise nature of the policy prior to the
    change, and Pepsi’s argument that there was in fact no change is not
    without record support. On balance, however, we find that substantial
    evidence supports the NLRB’s finding that Pepsi changed its policy
    so that unadjudicated citations immediately were counted against an
    employee’s driving record, and that this change led to the discharge
    of Hyatt, Lee, and Curtis, rendering it material. The NLRB therefore
    did not err in finding that Pepsi’s change to the moving violations and
    accidents policy was an impermissible unilateral change in the terms
    and conditions of employment.
    IV.
    Because the NLRB adduced sufficient evidence on remand indicat-
    ing that the Union did not waive the right to bargain over any of
    Pepsi’s unilateral changes to policy, because the evidence indicates
    that Pepsi’s withheld 1992 wage increase was not discretionary and
    was withheld based on anti-union animus, and because adequate evi-
    NLRB v. PEPSI-COLA                       19
    dence exists to permit the NLRB reasonably to conclude that each of
    Pepsi’s unilateral changes was material in nature, we grant enforce-
    ment of the NLRB’s order in full.
