    1
    The County of San Joaquin (County) filed a petition for writ of review relief in this
    court following a decision of the Public Employment Relations Board (Board), in which the
    Board found the County interfered with and discriminated against the protected activity of
    the California Nurses Association (Nurses) and its registered nurse members (members).
    Specifically, the Board found the County’s policy prohibiting members from returning to
    work after a noticed strike based on the County’s contract with a strike replacement
    company containing a minimum shift guarantee for replacement workers was conduct
    inherently destructive to protected activity. The Board then announced and applied a new
    test providing for a defense to the County’s conduct of threatening and implementing the
    policy and determined the County could not meet the standard set forth in the test. The
    Board also found the County’s refusal to permit members from using accrued leave for the
    time the members were prohibited from returning to work and the County’s determination
    the absences were unauthorized, thereby subjecting members to discipline, was conduct
    inherently destructive to protected activity. Accordingly, the Board ordered several
    remedies, including that the County allow members to use accrued leave for the time they
    were prohibited from returning to work and for similar absences in the future.
    We granted the County’s petition for writ of review relief and issued a writ of review.
    The County challenges several of the Board’s legal, factual, and remedial findings. After
    considering all of the briefs filed in this case, we affirm the Board’s decision in all respects.
    FACTUAL AND PROCEDURAL BACKGROUND
    I
    The Strike
    The County is a public agency within the meaning of the Meyers-Milias-Brown Act
    (Gov. Code,1 § 3500 et seq.) (Act) and the Board’s regulations. As one of its functions, the
    County operates the San Joaquin General Hospital (Hospital). The Hospital is a general
    1      Undesignated section references are to the Government Code.
    2
    acute care hospital that includes an emergency department, a neonatal intensive care unit,
    and the County’s only trauma center. The Hospital serves more indigent patients than any
    other hospital in the County and provides inpatient care to incarcerated patients in secure
    wards. The County also operates outpatient clinics in other locations within the County’s
    boundaries. In the first half of the 2019 to 2020 fiscal year, the Hospital lost substantially
    more money than expected. Nurses is an employee organization within the meaning of the
    Act and the exclusive representative of a bargaining unit comprised of more than 700
    members working at the Hospital and clinics within the County’s boundaries.
    The County and Nurses were involved in prolonged labor negotiations to bargain for
    a successor agreement to the memorandum of understanding between them. Between June
    and August 2019, the County sought proposals from three companies to provide
    replacement workers in the event of a strike. In October 2019, the County entered into a
    contract with Healthsource Global Staffing (Healthsource) to provide replacement workers
    in the event of a strike by Nurses and/or by Service Employees International Union Local
    1021 (Service Employees Union), which represented technical workers and other employees
    of the Hospital. As part of the strike replacement contract, the County agreed to “ ‘a
    minimum of what amounts to five (5) twelve-hour shifts (60 hours) for each Replacement
    Staff that commences travel to the Destination City. . . .’ ” Further, “ ‘[o]rientation provided
    to the Replacement Staff [was] billed at applicable Compensation Fee rates and [did] not
    count toward this minimum number of billable hours.’ ”2
    In January 2020, the County and Nurses reached an impasse in bargaining for a new
    memorandum of understanding, and postimpasse mediation did not resolve the impasse.
    Thus, on February 24, 2020, Nurses notified the County of its intention to strike at 7:00 a.m.
    on March 5, 2020, until 6:59 a.m. on March 7, 2020.
    2     Further details pertaining to the County’s negotiations of this contract will be
    recounted post.
    3
    Thereafter, the County filed an unfair practice charge and request for injunctive relief
    with the Board against Nurses to enjoin essential employees from striking. Following
    mediation, Nurses and the County entered into a settlement agreement on February 28,
    2020, whereby Nurses exempted multiple members from participating in the strike because
    those members were essential to delivering health care services. In advance of the strike,
    the County canceled some elective surgeries and outpatient clinic visits, reduced its intake
    of trauma patients, and otherwise reduced its overall number of patients. The County also
    learned that many employees represented by the Service Employees Union would strike in
    sympathy with Nurses.
    On March 3, 2020, the chief executive officer of the Hospital, David Culberson
    (Culberson), asked the San Joaquin County Board of Supervisors to retroactively approve
    the contract with Healthsource and the allocation of $4 million for replacement workers.
    The San Joaquin County Board of Supervisors approved Culberson’s request.
    On March 4, 2020, Culberson, sent a memorandum to “all [Nurses] Unit Members”
    regarding the date striking members could return to work (Culberson memo). The
    Culberson memo informed striking members that to ensure the County’s ability to deliver
    “necessary health services without interruption, including emergency services, the County
    has contracted with an outside company for replacement workers during the strike period.
    The company with which the County has contracted, however, will only agree to provide
    such replacement workers for a full five day period, and the County has therefore been
    forced to agree to pay a minimum of five full days for such workers[.] [¶] Given this
    unavoidable commitment, please know that [Nurses] unit members who participate in the
    strike will not be able to return to work at the end of the strike period as noticed by [Nurses].
    Instead, such participating employees will not be accepted back at work until their first
    shift on or after Tuesday, March 10 at 7 a.m., unless called into work at an earlier time
    by [the Hospital] management.”
    4
    The Culberson memo also informed striking members they might be notified not to
    return to work because of low patient census, at which time members would be furloughed
    pursuant to the memorandum of understanding between the County and Nurses.
    The memorandum of understanding between the County and Nurses sets forth
    furlough procedures in the event of “[f]luctuations in patient census” to accommodate
    “lower staffing needs.” In such an event, “the Hospital Director or designee may furlough
    any regular or contract employee . . . for up to thirty six (36) hours during any fiscal year,”
    subject to certain conditions. Enumerated as part of those conditions is that the Hospital
    “will make every attempt to seek volunteers before imposing mandatory furloughs” and
    employees will be called off in a particular order related to their employment status.
    Further, “[i]f an employee is notified that he or she is being furloughed and is then asked to
    report to work for the same shift, the employee will be guaranteed a full shift whether or not
    the employee works a full shift. Such an employee may not be ordered to return to work,
    and not required to be available if called.” Finally, “[members] who are furloughed may use
    up to 24 hours of vacation, compensatory time off or holiday hours to equal a full shift’s
    pay.”
    On March 5, 2020, the strike began. During the strike, and for three days after the
    strike, the County maintained a lower patient census, such that the number of patients was
    reduced from 150 patients to 120 patients. During the strike, the County continued to
    operate the Hospital by using Healthsource replacement workers, traveling or registered
    nurses already contracted to work for the County before the strike, supervisors and
    managers, and two categories of members -- those who were exempted from the strike
    pursuant to the settlement agreement and those who chose to work during the strike. The
    County did not have sufficient notice to hire replacements for employees represented by the
    Service Employees Union who chose to participate in a sympathy strike; however, the
    County was able to cover the sympathy strikers’ shifts by using Healthsource replacement
    5
    workers, supervisory personnel, and nonstriking employees represented by the Service
    Employees Union and Nurses.
    On March 7, 2020, the strike ended, and members attempted to return to work.3
    Between March 7 and March 9, 2020, the County continued to employ Healthsource
    replacement workers and barred most members who participated in the strike from returning
    to work. The County did not bar any employees represented by the Service Employees
    Union from returning to work. During this time, Nurses and multiple members believed the
    County had furloughed members under the memorandum of understanding, leading some
    members to claim vacation, compensatory time off, or holiday hours for the time they were
    barred from returning to work. Ultimately, the County determined members had not been
    furloughed under the memorandum of understanding and instead the County marked on
    members’ time cards that the leave was unauthorized. During the three days after the strike,
    when most members were barred from returning to work, the County attempted to call back
    to work some barred members due to understaffing. Many of the members who were called
    back refused to return to work, invoking the provision of the memorandum of understanding
    that permitted furloughed members to refuse callback requests.
    On April 9, 2020, Nurses filed a statement of amended charge with the Board against
    the County. On May 18, 2020, the Board issued a complaint against the County. The
    complaint alleged that on March 5 and 6, 2020, members exercised rights guaranteed by the
    Act by participating in a two-day strike. The complaint further alleged the County took
    adverse action against Nurses and its striking members which constituted discrimination
    against and interference with protected conduct, as well as a unilateral change in policies
    contained in the memorandum of understanding related to the furlough procedures. In its
    3       Further details pertaining to members’ efforts to return to work will be recounted
    post.
    6
    answer, the County denied its conduct amounted to adverse actions and raised several
    affirmative defenses to the allegations.
    II
    The Administrative Hearing
    A
    Contract Negotiations
    Chief nursing officer Belva Snyder testified at the administrative hearing on behalf of
    the County regarding the process she and her team undertook when selecting a strike
    replacement company. Snyder testified she had limited experience with strikes; specifically,
    she had been a hospital administrator during a threatened strike that had never materialized.
    As it pertained to the successive memorandum of understanding between the County and
    Nurses, Snyder was part of the County’s negotiating team and was present during
    negotiation sessions. By June 2019, the County and Nurses had been negotiating for quite
    some time and each party had brought very different proposals to the table without any
    resolution. Thus, in June 2019, Snyder started preparing for an anticipated strike by
    researching strike replacement companies. She had her team contact three companies --
    Maxim, Autumn, and Healthsource. In Snyder’s experience, the County preferred multiple
    proposals (typically, at least three) before contracting with any given company. Snyder did
    not contact any other strike replacement company and was unaware of any other companies
    in the field.
    As it pertained to Snyder’s search for a strike replacement company, Snyder wanted
    to find a company that would be able to provide the diversity and number of employees
    necessary to replace both the Service Employees Union and Nurses in the event the unions
    held a strike at the same time. She also wanted a vendor that was fiscally reasonable
    considering the “organization’s financial situation.” Further, Snyder wanted the
    replacement workers to have the skill sets needed to replace the various members in the
    different departments of the Hospital. It was Snyder’s understanding she would orient
    7
    replacement workers to the Hospital’s facility and procedures, but not to train them
    regarding patient care.
    The County had a current and long-standing contract with Maxim, a company that
    provided traveling nurses and was not a strike replacement company. Traveling nurses are
    typically used to fill vacancies while recruiting for permanent replacements or if there is a
    surge in patient census. Snyder removed Maxim from consideration early in the process
    because it could not provide replacements for employees represented by the Service
    Employees Union and because the Hospital was already having trouble with Maxim
    providing sufficient staffing for traveling nurse positions. Maxim did, however, submit a
    proposal to the County and required a minimum shift guarantee for its replacement workers
    of 48 hours, or four shifts of 12 hours, for each replacement nurse in the event of a two-day
    strike.
    Snyder and her team also contacted Autumn. Autumn offered a minimum shift
    guarantee of 48 hours for a two-day strike as well. Autumn submitted a proposal indicating
    that for each nurse ordered through their service, the County would be assessed a $1,200
    charge. Then, the County would be charged anywhere from $145 to $180 per hour for each
    replacement nurse. Snyder decided not to enter a contract for Autumn’s services because it
    was too expensive and because she had never worked with Autumn, making her uncertain
    about the level of service it could provide.
    Finally, Snyder and her team contacted Healthsource, with whom the County had a
    prior relationship during a threatened 2016 Nurses’ strike. While the 2016 strike never
    materialized, the County looked favorably on its interactions with Healthsource. Snyder
    was not yet an employee of the County at the time of the threatened 2016 strike, but she
    relied on the assertions of other Hospital staff that Healthsource had a good reputation. In
    Snyder’s conversations with Healthsource representatives, the representatives were
    confident they could provide the needed replacement workers for members of Nurses and
    for employees represented by the Service Employees Union. Healthsource charged $400
    8
    per replacement worker ordered, which it was able to do because the County signed a
    contract with it early in the strike preparation process. Healthsource required each
    replacement nurse to work a minimum of 60 hours, or five 12-hour shifts, for a two-day
    strike and receive one day of orientation not included as part of the minimum shift
    guarantee. Healthsource charged between $118 and $125 per hour for each replacement
    nurse. Snyder decided to enter a contract with Healthsource because it was overall less
    expensive than Autumn, Healthsource could confidently provide the broad range of
    replacement workers requested, and the County had a prior favorable experience with
    Healthsource.
    After deciding to enter a contract with Healthsource, Snyder negotiated the substance
    of the contract and became aware of several things. First, Healthsource’s minimum shift
    guarantee of 60 hours was a standard term in its contracts for two-day strikes. She was told
    this when she verbally inquired whether Healthsource could lower the 60-hour minimum.
    She did not ask about the minimum in writing or try to negotiate the term beyond being told
    it was a standard contract term. Snyder was not aware that Healthsource had agreed to a
    lower minimum shift guarantee in a contract with another hospital. Second, Healthsource
    did not want its replacement workers to come into contact with members of the union they
    would be replacing. To that end, Healthsource required the County to orchestrate the arrival
    of the replacement workers. For example, when the replacement workers began work at the
    start of the strike, they entered the Hospital through the rear entrance and members were
    required to exit the Hospital through the front entrance. Healthsource made an exception to
    this rule to allow replacement workers to work alongside essential employees, i.e., members
    who were enjoined from striking pursuant to the settlement agreement. Third, Healthsource
    required the County to agree to an exclusivity provision, meaning only Healthsource would
    provide the strike replacement workers. Healthsource made an exception to this provision
    for traveling nurses supplied by Maxim.
    9
    The contract between the County and Healthsource was entered into at the end of
    October, at a time when Snyder did not know how long a potential strike would last. Before
    doing so, Snyder negotiated to lower the interest rate for late or delayed payments. During
    her administrative hearing testimony, Snyder could not recall whether she told Healthsource
    representatives she had inquired with other companies regarding strike replacement
    services.
    Tabi Elbahou was vice president and general manager of Healthsource at the time it
    entered into the contract with the County. He did not recall the County attempting to
    negotiate over any term of the contract other than to lower the interest rate related to late or
    delayed payments, although most of the negotiations involved his employee and not him.
    Elbahou testified the County agreed to the standard contract language Healthsource offered,
    which included a term for a 60-hour minimum shift guarantee. Healthsource typically
    includes the provision so it can provide an aggressive and appealing compensation package
    for replacement workers and attract the right clinicians. To the best of Elbahou’s
    knowledge, Healthsource had entered into contracts with other hospitals with lower
    minimum shift guarantees. He believed the lower minimums occurred when the strikes in
    question were predicted to last fewer than three days; however, when shown a contract with
    contrary language, Elbahou could not speak to the circumstances of that contract because it
    was before he was employed with Healthsource. Elbahou testified that clients had tried to
    negotiate lower minimum shift guarantees, but no testimony was given pertaining to the
    outcome of those negotiations.
    B
    Poststrike Return To Work
    Following the two-day strike, members attempted to return to work for the morning
    shifts on March 7, 2020. Culberson, along with the Hospital’s security team, blocked
    members from entering the Hospital. Culberson testified at the administrative hearing that
    he told members shifts were adequately staffed, and they were not needed, except for a few
    10
    members who were permitted to return to work. Employees represented by the Service
    Employees Union, on the other hand, were all permitted to return to work because
    Healthsource replacement workers were not filling their positions. This was because the
    Service Employees Union did not provide notice of its sympathy strike, thus Healthsource
    could not prepare or deploy replacement workers for those striking employees.
    Members asked Culberson whether he was furloughing them under the memorandum
    of understanding. Culberson referred members to the Culberson memo. It was Nurses’ and
    members’ understanding that members were being furloughed under the memorandum of
    understanding. Culberson testified he was not clear about the reason members were being
    ordered not to return to work and may have misspoke when speaking about the reasons
    members were prohibited from returning to work. Culberson testified he never told
    members they were not being furloughed under the memorandum of understanding.
    Snyder testified it was her understanding the Culberson memo told striking members
    they could not return to work because of the replacement workers and would possibly be
    prevented from returning to work following the five-day period replacement workers were
    at the Hospital because of low patient census. The decision to prevent members from
    returning to work for the full five days replacement workers were contracted to work was a
    financial decision because the County could not afford to have double staffing at the
    Hospital. Snyder testified members were told they may be needed in the three-day period
    after the strike while replacement staff was present because patient census could increase or
    the Hospital could need members’ expertise. In that event, Snyder testified, the Culberson
    memo informed members they would be called into work.
    In the three days following the strike, Snyder determined she needed more nursing
    staff in addition to the Healthsource replacement workers, essential employees, and
    traveling nurses, which Healthsource allowed to continue working during its contract term
    with the County. Indeed, the County had contracts with multiple traveling nurse companies
    at the time of the strike and three-day overlap period. One reason staff was needed was
    11
    because essential employees enjoined from striking were not enjoined after the noticed
    strike and could no longer be forced to work. Based on the determination that additional
    nursing staff was needed, Snyder called multiple members to return to work. Many of those
    members refused to return to work believing they could refuse under the furlough provision
    of the memorandum of understanding. Snyder testified that, when calling staff to return to
    work, she called nurses who possessed the skills to replace the essential employees who
    were no longer compelled to work pursuant to the settlement agreement between Nurses and
    the County. Thus, in the event she called a traveling nurse instead of a member, it was
    because the traveling nurse possessed the skills necessary to replace an essential worker.
    When filling out time cards, members attempted to use accrued leave for the three
    days following the strike. The County denied members’ attempts to use accrued leave and
    instead marked the leave as unauthorized. This was true regardless of whether the member
    refused to return to work and applied to all members who had a shift scheduled for the days
    following the strike when members were barred from returning to work. The County
    decided not to honor members’ accrued leave requests because it would result in the County
    paying two sets of staff. Members who were scheduled to be on standby were paid as
    standby employees for the three days following the strike.
    Unauthorized leave means a member was not present for work when scheduled to
    work and the time card notation can be used as a basis for discipline. Because the leave was
    unauthorized, some members did not accrue enough working time within the pay period to
    entitle them to vacation or retirement benefits and their longevity pay raises were delayed.
    III
    The Board’s Decision
    The Board issued its decision on April 12, 2021. The Board dismissed the unilateral
    change claim alleged in the complaint, but concluded the County violated the Act and Board
    regulations by discriminating against and interfering with Nurses’ and members’ protected
    striking activity. To come to this conclusion, the Board applied the “well-established
    12
    interference and discrimination standards” to several adverse actions taken by the County.
    These adverse actions were the County’s conduct of “threatening to disallow strikers from
    work for multiple days after the strike, implementing that action, refusing to allow nurses to
    use paid time off for the period following the strike in which they were barred from work,
    and designating employees’ strike time and time following the strike as [unauthorized
    leave].”4
    The Board concluded the first two adverse actions pertaining to the County’s policy
    to disallow striking members from returning to work for multiple days after the strike
    amounted to conduct that was inherently destructive to protected striking activity. The
    Board then recognized it had adopted the affirmative defense framework governing private
    sector employers announced in NLRB v. Great Dane Trailers, Inc. (1967) 
    388 U.S. 26
     [
    18 L.Ed.2d 1027
    ] (Great Dane) to both interference and discrimination cases involving public
    employers. The Board explained that it was applying this framework to the unique set of
    facts pertaining to the County’s inherently destructive conduct. When applying this
    standard, the Board reviewed “[f]ederal decisions [that] have repeatedly considered strike
    replacement contracts with minimum [shift] guarantee provisions and, in a parallel line of
    cases, partial lockouts featuring alleged discrimination against protected activity. [It
    determined, t]hese decisions lay out neither a consistent analytic framework nor an approach
    [the Board] f[ou]nd fully persuasive in interpreting the [Act].”
    Thus, the Board formed a three-part test under which a public health care employer
    that prohibits bargaining unit employees from work after a strike due to a minimum shift
    guarantee for strike replacement workers could typically establish an affirmative defense.
    The test requires a public health care employer to “prove that: (1) it made a good faith
    4      The County later decided not to enforce the unauthorized leave designation as a basis
    for discipline. The Board did not consider this a retraction of the adverse action because the
    County’s decision occurred five months after the initial conduct, making the decision
    untimely, and thus failing to meet the legal standard of a retraction.
    13
    effort in the marketplace to negotiate a strike replacement contract that would eliminate any
    minimum shift guarantee or shorten it to the greatest degree possible, but it ultimately
    needed to agree to the minimum shift guarantee in order to maintain critical health care
    services; (2) it barred employees from work only because such a contractual commitment
    temporarily reduced available work opportunities, and it filled all remaining opportunities
    without discriminating against employees based on whether they worked during the strike or
    engaged in any other actual or perceived protected activity; and (3) it provided the
    employees’ union with timely notice regarding any decision to guarantee replacement
    workers a minimum work period or to modify the terms of such a guarantee, and if
    requested, bargained in good faith over the potential effects on bargaining unit employees.”
    Applying this test, the Board found the County could not avail itself of the
    affirmative defense because it did not establish that it made a good faith effort to eliminate
    the minimum shift guarantee or shorten it to the greatest degree possible, it granted
    preference to members who did not strike when determining who worked after the strike,
    and it failed to provide Nurses with adequate notice of Healthsource’s contracted minimum
    shift guarantee.
    The Board then analyzed whether the County interfered or discriminated against
    protected rights when it refused to allow members to use paid leave for the period after the
    strike or when designating the time during which they were barred from returning to work
    as unauthorized leave. The Board determined the County did interfere with and
    discriminate against protected activity and the County could not avail itself of the
    affirmative defense outlined in Great Dane under either the inherently destructive standard
    or the less burdensome comparatively slight standard because the County could not justify
    its conduct with a valid business reason.
    As a result of the Board’s findings, it determined the appropriate remedy was to
    permit members to use paid leave for the period after the strike, even if members refused to
    return to work when called to return. The Board found that while members were not
    14
    furloughed due to low patient census under the memorandum of understanding, members
    were reasonably confused given Culberson’s statements, and members understandably
    asserted rights under the memorandum of understanding to not return to work. Given the
    policy that remedial orders should make injured parties whole and deter future interference
    and discrimination, the Board found it necessary to order the County to allow members to
    use accrued leave for the three days they were barred from work. The Board further
    ordered, “[u]nless the parties agree otherwise, [the County was to] permit [members] to use
    paid leave time for furloughs occasioned by a minimum shift guarantee in a strike
    replacement contract to the same extent as is permitted for furloughs resulting from reduced
    patient census or other business reasons.”
    The County filed a petition for writ of review relief in this court. We granted the
    petition and issued a writ of review.
    DISCUSSION
    I
    The Act And Applicable Board Standards
    It is the express purpose of the Act “to promote full communication between public
    employers and their employees by providing a reasonable method of resolving disputes
    regarding wages, hours, and other terms and conditions of employment between public
    employers and public employee organizations.” (§ 3500.) Section 3506 provides: “Public
    agencies and employee organizations shall not interfere with, intimidate, restrain, coerce or
    discriminate against public employees because of their exercise of their rights under Section
    3502.” Section 3502 provides in relevant part: “Except as otherwise provided by the
    Legislature, public employees shall have the right to form, join, and participate in the
    activities of employee organizations of their own choosing for the purpose of representation
    on all matters of employer-employee relations.”
    Section 3506.5, subdivision (a), similarly makes it unlawful for a public agency to
    “[i]mpose or threaten to impose reprisals on employees, to discriminate or threaten to
    15
    discriminate against employees, or otherwise to interfere with, restrain, or coerce employees
    because of their exercise of rights guaranteed by [the Act],” while subdivision (b) of the
    same section makes it unlawful for a public agency to “[d]eny to employee organizations the
    rights guaranteed to them by [the Act],” including the right of recognized employee
    organizations “to represent their members in their employment relations with public
    agencies.” (§ 3503; Los Angeles County Employees Assn. v. County of Los Angeles (1985)
    
    168 Cal.App.3d 683
    , 687; County of Riverside (2010) PERB Dec. No. 2119-M at pp. 20-21,
    23 [34 PERC ¶ 108].)
    The Act parallels the National Labor Relations Act (
    29 U.S.C. § 151
     et seq.), and
    when interpreting the Act, it is proper to look to federal authority for its persuasive value.
    (Social Workers’ Union, Local 535 v. Alameda County Welfare Dept. (1974) 
    11 Cal.3d 382
    ,
    391; Vernon Fire Fighters v. City of Vernon (1980) 
    107 Cal.App.3d 802
    , 815.) Over the
    years, the Board and California’s courts have developed several tests for analyzing
    allegations arising under the above provisions of the Act and the virtually identical language
    of other Board-administered statutes. (See, e.g., Campbell Municipal Employees Assn. v.
    City of Campbell (1982) 
    131 Cal.App.3d 416
    , 424-425; Los Angeles County Superior Court
    (2018) PERB Dec. No. 2566-C at p. 15 [43 PERC ¶ 1]; Novato Unified School District
    (1982) PERB Dec. No. 0210-E at pp. 3-7 [6 PERC ¶ 13114]; Carlsbad Unified School
    District (1979) PERB Dec. No. 0089-E at pp. 10-11 [3 PERC ¶ 10031] (Carlsbad).)
    Broadly speaking, the various conduct proscribed by sections 3506 and 3506.5 may be
    characterized as either interference or discrimination. (Los Angeles Superior Court, at pp.
    24-25, fn. 17.)
    When a charging party has established a prima facie case of interference or
    discrimination, the burden shifts to the employer to prove an affirmative defense.5 (Great
    5       The County does not dispute that Nurses established a prima facie case of
    interference and discrimination as to its adverse actions of threatening and then
    16
    Dane, supra, 388 U.S. at pp. 33-34 [18 L.Ed.2d at pp. 1034-1035].) The Board applies the
    same standard established in Great Dane for discrimination claims, but unlike Great Dane,
    the standard is applicable to both interference and discrimination claims. (See Campbell
    Municipal Employees Assn. v. City of Campbell, supra, 131 Cal.App.3d at p. 423 [applying
    the affirmative defense announced in Great Dane to an interference claim].) If the harm to
    employee rights is “ ‘ “comparatively slight,” ’ ” then the employer has the opportunity to
    provide evidence that its actions were motivated by legitimate and substantial business
    justifications. (Campbell, at p. 424, citing Great Dane, at p. 34 [18 L.Ed.2d at p. 1035];
    Carlsbad, supra, PERB Dec. No. 0089-E at pp. 10-11.) If, on the other hand, the
    employer’s conduct is “ ‘ “inherently destructive” of important employee rights, no proof of
    antiunion motivation is needed . . . .’ ” (Campbell, at p. 423.) In those instances, the
    employer’s conduct will be excused only on proof that it was occasioned by circumstances
    beyond the employer’s control and that no alternative course of action was available.
    (Carlsbad, at pp. 10-11.)
    II
    The Board’s Legal Determinations Were Not Clearly Erroneous6
    The County raises several issues pertaining to the Board’s legal determinations.
    These claims can be divided into three main issues: (1) the Board improperly determined
    the County’s adverse actions of threatening and implementing a policy prohibiting striking
    members from returning to work following the strike amounted to inherently destructive
    implementing a delayed return-to-work schedule based on the hiring of strike replacement
    workers with a minimum shift guarantee.
    6      Because we conclude the Board’s decision was not clearly erroneous insofar as it
    determined the County’s refusal to allow striking members to return to work amounted to
    inherently destructive conduct and announced a new test applicable to public health care
    employers who utilize strike replacement services, we need not address the County’s
    appellate claim it would have prevailed under a comparatively slight affirmative defense
    framework.
    17
    conduct; (2) the Board’s newly announced test pertaining to contracts with strike
    replacement companies is illogical and not supported by Board precedent or federal
    authority; and (3) the Board improperly determined the County’s failure to allow members
    to use paid leave for the three days following the strike interfered with and discriminated
    against protected activity.
    When reviewing these claims, “[i]t is settled that ‘[c]ourts generally defer to [the
    Board]’s construction of labor law provisions within its jurisdiction.’ ” (Boling v. Public
    Employment Relations Bd. (2018) 
    5 Cal.5th 898
    , 911.) “ ‘We follow [the Board]’s
    interpretation unless it is clearly erroneous.’ ” (Id. at p. 912; County of Los Angeles v. Los
    Angeles County Employee Relations Com. (2013) 
    56 Cal.4th 905
    , 922.) “[W]ithin [the
    Board]’s area of expertise, the deferential standard . . . applies to [the Board’s] legal
    determinations even if based on undisputed facts.” (Boling, at p. 913.)
    A
    The Board’s Determination The County’s Delayed Return-To-Work
    Policy For Striking Members Amounted To Inherently
    Destructive Conduct Was Not Clearly Erroneous
    When analyzing the degree to which the County’s conduct infringed on Nurses’ and
    members’ protected rights as it pertained to the interference claim, the Board reasoned:
    “Denying work opportunities following a strike significantly coerces protected rights by
    discouraging employees from authorizing future strikes, and therefore gives rise to a robust
    duty to narrowly tailor.” As it pertained to the discrimination claim, the Board further
    stated: “if a hospital denied work opportunities to a greater degree for those who have
    engaged in protected activity, such conduct is facially discriminatory, and the significantly
    coercive impact rises to the level of inherently destructive.”
    The County contends this determination was clearly erroneous because the Board’s
    analysis failed to distinguish between conduct that is inherently destructive as opposed to
    18
    inherently discriminatory, failed to comply with its own precedent, and unjustifiably
    rejected federal authority. We disagree.
    The Board’s stated reasons imply it believed the County’s conduct was not merely
    discriminatory, but that the County’s conduct resulted in a negative and prolonged impact
    on Nurses’ willingness to strike as a means of bargaining in the future. Indeed, the Board
    pointed to the fact that the County’s conduct discouraged future strikes. Although these
    reasons do not state a standard or grapple with the tension between the definitions of
    discriminatory and destructive conduct to the County’s liking, the County has not directed
    us to any requirement the Board must first recite the rules it applies or engage in a specific
    analysis before announcing its determinations. To require the Board to do so would elevate
    form over substance and fall outside our review of whether the Board’s legal determinations
    are clearly erroneous.
    The County cites to Berkeley as stating the proper standard to apply when
    determining whether an employer’s conduct was inherently destructive or comparatively
    slight. (Regents of the University of California (Berkeley) (2018) PERB Dec. No. 2610-H
    [43 PERC ¶ 100].) There, the Berkeley Board observed it had “never identified or explained
    what distinguishes comparatively slight harm from inherently destructive conduct.”
    (Berkeley, at p. 58.) The Berkeley Board then considered several of its own decisions and
    National Labor Relation Board decisions. The Berkeley Board stated it defined inherently
    destructive conduct as the “ ‘natural and probable consequence’ [of which] would be to
    discourage the exercise of [protected] rights” or “would tend to discourage both present and
    future protected activity.” (Berkeley, at pp. 58, 59.) As to National Labor Relation Board
    decisions, the Berkeley Board observed federal authorities have defined inherently
    destructive conduct as that which “typically ‘creat[es] visible and continuing obstacles to the
    future exercise of employee rights’ or has ‘far reaching effects which could hinder future
    bargaining.’ ” (Berkeley, at p. 86.) With this in mind, the Berkeley Board noted, the
    National Labor Relations Board and federal courts “consider the temporal impact or likely
    19
    duration of [the conduct’s] effect on protected activity.” (Berkeley, at p. 86.) Indeed, the
    National Labor Relations Board explained in International Paper Company “that, in
    evaluating the temporal impact on protected rights, both ‘the severity of the harm suffered
    by the employees for exercising their rights’ and ‘the severity of the impact on the statutory
    right being exercised’ should be considered.” (Berkeley, at p. 87, quoting Int’l Paper Co.
    (1995) 
    319 NLRB 1253
    , 1269.)
    The Berkeley Board pointed to several examples of inherently destructive conduct
    under both state and federal authority. These examples include: “conduct directed against a
    union officer, steward or other employee representative, in his or her capacity as an
    employee representative”; “employer speech . . . when it contains express or implied threats,
    when it is likely to discourage employees from seeking union assistance, from using the
    collectively-bargained grievance procedure, or from engaging in other protected conduct, or
    when it conveys the message that collective bargaining is futile”; “an employer’s outright or
    facial ban on union or other protected activity in non-working areas and during non-working
    time”; “an employer’s prohibition against union officers representing bargaining-unit
    employees in investigative meetings”; and “conditioning a pay increase on surrendering
    protected rights.” (Berkeley, supra, PERB Dec. No. 2610-H at pp. 59, 60, 61, 87.)
    Here, the Board considered the effect the County’s conduct had on future protected
    activity and the severity of the County’s conduct on striking members. The Board
    determined the County’s conduct was “significantly coercive.” The Board further found the
    County’s conduct “discourag[ed] employees from authorizing future strikes.” (Italics
    added.) Indeed, the County’s conduct targeted only those members who participated in the
    strike, not those members who were exempt or crossed the picket line, whom the County
    permitted to work in the days following the strike without qualification. By targeting only
    striking members the night before the noticed strike with a delayed return-to-work schedule
    that more than doubled the length of the strike, the County demonstrated to Nurses and
    members that striking was not an effective means of bargaining, i.e., futile, because the
    20
    length of the strike and the consequences thereof were unavoidable and out of Nurses’ and
    members’ control. This is similar to many of the examples cited by the Board in Berkeley.
    (See Berkeley, supra, PERB Dec. No. 2610-H at pp. 59-61, 87.) Accordingly, the Board’s
    determination complied with its precedent and was not clearly erroneous on this basis.
    Similarly, the Board’s finding the County engaged in inherently destructive conduct
    does not impermissibly deviate from federal authority. The County argues the Board
    ignored Pacific Mutual Door Co. (1986) 
    278 NLRB 854
     (Pacific Mutual Door) and nearly
    every other subsequent National Labor Relations Board decision, finding employer conduct
    similar to that of the County’s conduct was not inherently destructive. (Citing
    Knightsbridge Heights Rehabilitation Care Center (2008) 
    352 NLRB 6
    ; Sutter Roseville
    Medical Center (2006) 
    348 NLRB 637
    ; AMI/HTI Tarzana-Encino Joint Venture d/b/a
    Encino Tarzana Regional Medical Center (2000) 
    332 NLRB 914
     (Encino Tarzana); Harvey
    Mfg., Inc. (1992) 
    309 NLRB 465
    .) But the Board addressed these federal decisions,
    ultimately finding them inadequate considering the realities of public sector labor relations.
    The Board is permitted to depart from federal law when it supplies a reasoned basis
    particular to the context of California public sector labor law for doing so. (McPherson v.
    Public Employment Relations Bd. (1987) 
    189 Cal.App.3d 293
    , 307-308; see Agricultural
    Labor Relations Bd. v. Superior Court (1976) 
    16 Cal.3d 392
    , 412-413.) Further, while the
    Act parallels the National Labor Relations Act, federal authority is merely persuasive.
    (Social Workers’ Union, Local 535 v. Alameda County Welfare Dept., supra, 11 Cal.3d at p.
    391; Vernon Fire Fighters v. City of Vernon, supra, 107 Cal.App.3d at p. 815.)
    Here, the Board diverged from federal authority given the differences between the
    public employment relationships governed under the Act and the private employment
    relationships governed under the National Labor Relations Act. Specifically, the Board
    reasoned “[e]mployers and unions under our jurisdiction each face stricter limits on their use
    of economic weapons than the restrictions governing their private sector counterparts. For
    instance, it is an unfair practice for a public sector union strike to cause an imminent and
    21
    substantial threat to the public’s health or safety, and a union may lawfully strike pre-
    impasse only based upon employer unfair practices. [Citations.] Employers, for their part,
    cannot lock out employees or permanently replace strikers, among other restrictions.
    [Citation.] These principles not only make inapposite private sector caselaw allowing an
    employer to disfavor strikers if it has made permanent new arrangements during an
    economic strike, but also aid us in discerning the boundaries that apply to the County’s
    conduct, which bears characteristics akin to a lockout.”
    The County argues these grounds are insufficient to justify the Board’s
    characterization of its conduct as inherently destructive as opposed to comparatively slight
    because there is no link between the stricter limits the Board has imposed in the past and the
    County’s conduct here. Not so. The Board “bring[s] expertise and uniformity to the
    delicate task of stabilizing labor relations.” (San Diego Teachers Assn. v. Superior Court
    (1979) 
    24 Cal.3d 1
    , 12.) It is guided by the purposes of the Act: “(1) to promote full
    communication between public employers and employees, and (2) to improve personnel
    management and employer-employee relations. (§ 3500.)” (Claremont Police Officers
    Assn. v. City of Claremont (2006) 
    39 Cal.4th 623
    , 630.)
    To fulfill this purpose, the Board has imposed limitations on the bargaining process
    nonexistent in private labor relationships. For example, the Board has prohibited the
    permanent replacement of striking workers. (Compare Fremont Unified School Dist. (1990)
    PERB Dec. No. 1054-E at pp. 10-11 [14 PERC ¶ 21107] with Vessey & Co. v. Agricultural
    Labor Relations Bd. (1989) 
    210 Cal.App.3d 629
    , 654, citing National Labor Rel. Bd. v.
    Mackay Radio & T. Co. (1938) 
    304 U.S. 333
    , 345-346 [
    82 L.Ed. 1381
    , 1389-1390] [if a
    private employer has permanently filled a position held by an economic striker before
    receiving the striker’s offer to return to work, the striker is entitled to reinstatement as jobs
    become available].) The Board has also prohibited employees from striking before an
    impasse except on specified grounds. (Compare County of Trinity (United Public
    Employees of California, Local 792) (2016) PERB Dec. No. 2480-M at p. 3 [40 PERC ¶
    22
    171] [a strike occurring before an impasse and completion of any required impasse
    procedures creates a rebuttable presumption the union has breached its duty to bargain in
    good faith] with N.L.R.B. v. Insurance Agents’ International (1960) 
    361 U.S. 477
    , 489-491
    [
    4 L.Ed.2d 454
    , 463-466] [National Labor Relations Board lacks authority to limit a union’s
    economic tools, including to prohibit it from striking before an impasse].) The Board has
    further allowed employers to enjoin potentially striking employees from striking if the
    absence of those employees would harm public health or safety. (City of San Jose v.
    Operating Engineers Local Union No. 3 (2010) 
    49 Cal.4th 597
    , 611; County Sanitation
    Dist. No. 2 v. Los Angeles County Employees’ Assn. (1985) 
    38 Cal.3d 564
    , 585-587.)
    Given the restrictions in place for public labor relationships that do not exist for their
    private counterparts, the County’s conduct would be perceived differently by a public-sector
    employee subject to the additional restrictions in comparison to a private-sector employee
    not subject to those restrictions. For example, a private-sector employee, like the employees
    in Pacific Mutual Door, would not see the inability to return to work for 30 days following
    the end of a strike inherently destructive to the right to strike when that same employee risks
    permanent replacement, and the inability to return to work at all, by choosing to strike.
    (Pacific Mutual Door, supra, 278 NLRB at pp. 855-856.) Similarly, a private-sector union
    would not perceive the inability to promptly return to work inherently destructive if it too
    had strong economic weapons, like the ability to call a strike before an impasse and for all
    its members to strike regardless of their importance to the business’s functionality. Instead,
    public-sector employees, like members here, face restrictions on when they can strike and
    the detrimental effect of their strike, under the promise they can return to their jobs. This
    playing field allows the risk public-sector employees undertake to be more predictable and
    within their own control. Taking control from the public-sector employee by extending a
    strike period (in this case more than doubling the strike period) serves to unpredictably
    increase the risk the employee undertakes and undoubtedly discourages future striking
    23
    activity to a greater degree than on the federal landscape. Thus, the Board’s departure from
    federal authority was justified.
    Still, the County disagrees, arguing the Board misjudged the labor negotiation
    playing field by failing to consider the narrow conditions necessary for an injunction and the
    federal law excepting supervisors from the definition of employees, thus making supervisors
    incapable of participating in a strike, unlike the case here. (See Santa Clara County
    Counsel Attys. Assn. v. Woodside (1994) 
    7 Cal.4th 525
    , 537). We are not persuaded. As
    discussed, the Board’s departure from federal law has a justified basis grounded in the
    particulars of California public-sector labor law. Applying the clearly erroneous standard of
    review, the County cannot demonstrate the Board acted in excess of its authority when
    determining the County’s conduct was inherently destructive.
    B
    The Board’s Newly Announced Test Pertaining To Contracts With Strike
    Replacement Companies In Public Health Care Settings Was Not Clearly Erroneous
    The County contends the Board’s newly announced three-part test is clearly
    erroneous by attacking all three parts of the test. Again, the test requires a public health care
    employer to “prove that: (1) it made a good faith effort in the marketplace to negotiate a
    strike replacement contract that would eliminate any minimum shift guarantee or shorten it
    to the greatest degree possible, but it ultimately needed to agree to the minimum shift
    guarantee in order to maintain critical health care services; (2) it barred employees from
    work only because such a contractual commitment temporarily reduced available work
    opportunities, and it filled all remaining opportunities without discriminating against
    employees based on whether they worked during the strike or engaged in any other actual or
    perceived protected activity; and (3) it provided the employees’ union with timely notice
    regarding any decision to guarantee replacement workers a minimum work period or to
    modify the terms of such a guarantee, and, if requested, bargained in good faith over the
    potential effects on bargaining unit employees.”
    24
    1
    Part One
    As it pertains to the first part, the County argues the test’s assessment of an
    employer’s “good faith effort in the marketplace to negotiate a strike replacement contract
    that would eliminate any minimum shift guarantee or shorten it to the greatest degree
    possible” necessarily views the hiring of a strike replacement company as inherently
    destructive conduct and requires an employer to choose the contract with the shortest shift
    guarantee without regard to countervailing interests. This is so, the County argues, despite
    the Board’s exception stated within the test itself that the health care employer could
    ultimately agree to a longer shift guarantee “in order to maintain critical health care
    services.” We disagree.
    The Board’s decision does not suggest it believed entering into a replacement
    contract containing a minimum shift guarantee would always constitute conduct inherently
    destructive to protected rights. The Board determined the County’s use of this type of
    contract was inherently destructive. The decision lays out a three-part test to be read in light
    of an inherently destructive or comparatively slight finding.
    Comparatively slight conduct is excused upon evidence the employer’s actions were
    motivated by legitimate and substantial business justifications. (Campbell Municipal
    Employees Assn. v. City of Campbell, supra, 131 Cal.App.3d at p. 424.) But, when
    considering comparatively slight conduct, the stronger the tendency to harm, the greater the
    employer’s burden to show its business need was important and that it narrowly tailored its
    actions or rules to attain that purpose while limiting harm to protected rights as much as
    possible. (City of San Diego (2020) PERB Decision No. 2747-M at p. 36, fn. 19 [45 PERC
    ¶ 45].) Thus, while an inherently destructive standard requires the most tailoring,
    comparatively slight conduct produces a sliding scale dependent on the level of harm
    inflicted by an employer. This sliding scale is consistent with the first part of the test that
    balances an employer’s good faith effort to eliminate minimum shift guarantees from
    25
    contracts with strike replacement companies against its ability to maintain critical health
    care services. Indeed, the standards fit together well.
    As the County argues, there are various concerns relevant to a health care employers’
    efforts to hire replacement workers and maintain critical health care services, including the
    quality of the replacement workers offered, a hospital’s prior experience with the
    replacement company, the reliability of the replacement staff offered, and how the
    replacement company otherwise serves a hospital’s needs. Under a comparatively slight
    framework, these considerations are relevant to whether a hospital tailored its legitimate and
    substantial business justifications to the need to hire replacement workers with a minimum
    shift guarantee and is also relevant to an inherently destructive framework to demonstrate a
    hospital acted out of a business necessity. The test announced by the Board allows for the
    nuance the County demands and does not treat every employer who enters a strike
    replacement contract containing a minimum shift guarantee as having committed inherently
    destructive conduct. Nor does the test provide an illusory balancing of hospital interests.
    The County also challenges the first part of the test by pointing to various National
    Labor Relations Board decisions for the proposition that those decisions did not require
    employers to shop around for a strike replacement company with a lower minimum shift
    guarantee. (Citing Pacific Mutual Door Co., 
    supra,
     278 NLRB at p. 854; Sutter Roseville
    Medical Center, supra, 348 NLRB at p. 637; Encino Tarzana, supra, 332 NLRB at p. 914;
    Roosevelt Memorial Medical Center (2006) 
    348 NLRB 1016
    .) These decisions are the same
    decisions the County cited when arguing the Board impermissibly diverged from federal
    authority by declaring its conduct inherently destructive. For the same reasons we
    concluded that divergence justified, i.e., the stricter limits on public employers’ use of
    economic weapons compared to the restrictions governing their private sector counterparts,
    we conclude the Board’s divergence from federal authority in this regard justified as well.
    (See McPherson v. Public Employment Relations Bd., supra, 189 Cal.App.3d at pp. 307-
    308.)
    26
    2
    Part Two
    The County challenges the second part of the Board’s test -- that a hospital-employer
    is permitted to bar employees from work only when the minimum shift guarantee reduced
    work opportunities, but must offer remaining work opportunities without discriminating
    against those who participated in protected activity -- on the ground that federal law permits
    employers to bar employees from work for the entire duration of the strike replacement
    contract regardless of work opportunities in the period between the conclusion of a strike
    and the end of the minimum shift guarantee. We agree with the Board that federal authority
    pertaining to strike replacement contracts is confusing as to how an employer must offer
    available work opportunities in the period following a strike and before the end of a
    minimum shift guarantee.
    The County relies again on Pacific Mutual Door, Sutter Roseville Medical Center,
    Encino Tarzana, and Roosevelt Memorial Medical Center for its argument to undercut the
    second part to the Board’s test. While the National Labor Relations Board broadly stated a
    rule in Encino Tarzana, supra, 332 NLRB at pages 917-918, and Sutter Roseville Medical
    Center, supra, 348 NLRB at page 642, purportedly from Pacific Mutual Door, supra, 278
    NLRB at page 856, that until a minimum shift guarantee has been canceled or satisfied, an
    employer has a legitimate and substantial business justification for delaying reinstatement of
    strikers, that broad rule is not called into question here. Indeed, the Board adopted a
    substantially similar standard in the second part of its test by recognizing minimum shift
    guarantees as a justified reason to deny work opportunities to striking employees after a
    strike has ended.
    As it pertains to how an employer offers work opportunities not covered by
    replacement workers in the period after a strike but before the end of the minimum shift
    guarantee, Pacific Door and Encino Tarzana are silent. (Encino Tarzana, supra, 332 NLRB
    at p. 918 [“The only reason that everyone who was scheduled during the Three-Day Period
    27
    was not needed was the lawful presence of the temporary replacements”]; Pacific Door,
    supra, 278 NLRB at pp. 855-856.) “ ‘It is axiomatic that cases are not authority for
    propositions not considered.’ ” (In re Marriage of Cornejo (1996) 
    13 Cal.4th 381
    , 388.)
    Sutter Roseville Medical Center, on the other hand, supports the second part of the
    Board’s test. There, the union “conceded the Respondent [Hospital] had a legitimate
    business justification for retaining the employment agency-supplied temporary employees
    for the period for which they were contracted” but the National Labor Relations Board
    found it unlawful to fill available poststrike work opportunities with supervisors and
    transferees not affiliated with the employment agency instead of striking employees. (Sutter
    Roseville Medical Center, supra, 348 NLRB at pp. 645-647.) Similarly, in Roosevelt
    Memorial Medical Center, a union notified a hospital of a strike prompting a hospital
    administrator to hire replacement workers with a minimum shift guarantee. The union
    thereafter called off the strike and the hospital administrator reworked the schedule to
    integrate as many striking employees as possible to work as close to their prestrike hours as
    possible. The National Labor Relations Board found the hospital’s conduct comparatively
    slight and its unilateral scheduling (because the union refused to participate when requested)
    lawful given the efforts taken by the administrator and the few employees who were
    affected by the schedule change.7 (Roosevelt Memorial Medical Center, supra, 348 NLRB
    at pp. 1017-1021.) Both of these cases stand for the proposition adopted by the Board that
    strikers can be denied work based on a minimum shift guarantee, but to the extent work
    7       Roosevelt Memorial Medical Center provides an example of how a hospital’s
    conduct in hiring strike replacement companies with minimum shift guarantees can be
    determined comparatively slight, as opposed to inherently destructive, and a hospital’s
    efforts can potentially satisfy the Board’s three-part test. Indeed, the National Labor
    Relations Board noted how the hospital administrator’s efforts showed potentially striking
    members that striking was not futile or discouraged, and any detriment was felt temporarily
    instead of targeted at future protected activity. (Roosevelt Memorial Medical Center, supra,
    348 NLRB at pp. 1018-1019.)
    28
    opportunities arise, those opportunities must be offered on a nondiscriminatory basis. (See
    also The Waterbury Hospital (1990) 
    300 NLRB 992
    , 1007 [when no permanent
    replacements hired, employers must reinstate all employees (both strikers and nonstrikers)
    equally].) Accordingly, the second part of the Board’s test is not clearly erroneous.
    3
    Part Three
    The County challenges the third part of the Board’s new test -- that a hospital-
    employer provide a union with timely notice of a decision to hire replacement workers with
    a minimum shift guarantee, and if requested, bargain in good faith over the potential impacts
    on bargaining unit employees -- on seven grounds.
    First, the County argues it has the unquestionable right to prepare for a strike of its
    health care employees, including by hiring replacement workers. Indeed, the County
    argues, the hiring of replacement workers is similar to other strike preparations typically
    performed confidentially. But the County fails to cite any legal authority for this
    proposition. (See Cal. Rules of Court, rule 8.204(a)(1)(B) [parties must “support each point
    by argument and, if possible, by citation of authority” otherwise the contention is forfeited];
    McComber v. Wells (1999) 
    72 Cal.App.4th 512
    , 522.) Moreover, notifying union members
    of a minimum shift guarantee for replacement workers or bargaining with them regarding
    the impacts of such a decision does not inhibit an employer’s ability to prepare for a strike
    or otherwise minimize the disruption to an employer’s business. To be sure, the test does
    not require an employer to secure its employees’ permission before entering into a contract
    with a strike replacement company. In fact, communicating with employees about the
    minimum shift guarantee with replacement workers would have minimized the disruption
    here and established clear standards instead of the confusion that resulted from the surprise
    minimum term and available leave designations. (See § 3500 [purpose of the Act is to
    promote communication between employers and employees].)
    29
    Second, the County argues part three of the newly enacted test is clearly erroneous
    because it imposes a one-sided duty on the employer to provide notice of a minimum shift
    guarantee and to bargain with union members regarding the impacts of such a contract term.
    To the County, a union would have an incentive to increase costs to the County under these
    circumstances, and the County would have no comparable opportunity to minimize the
    effects of the strike. Similarly, the County’s remaining arguments pertain to a union’s
    incentive to use an employer’s newly enacted duty to bargain over strike impacts as a way to
    file more charges before the Board and stall otherwise substantive and productive
    negotiations between the union and the employer.
    The County has failed to demonstrate how these policy considerations could lead to a
    clearly erroneous conclusion on our part. Indeed, the County does not argue this part of the
    test is contrary to Board precedent or federal authority. It instead presents multiple policy
    considerations in an attempt to guide us to the conclusion the test is a bad idea. But the
    Board’s duties are two-fold: “(1) to promote full communication between public employers
    and employees, and (2) to improve personnel management and employer-employee
    relations.” (Claremont Police Officers Assn. v. City of Claremont, 
    supra,
     39 Cal.4th at p.
    630.) The third part of the Board’s test clearly seeks to foster these purposes and lead to
    better communication and relations between public health care employers and their
    employees.
    Finally, the County argues the Board’s consideration of this factor is particularly
    unfair because there was no allegation in the complaint the County violated the Act by
    failing to notify Nurses it entered into a contract with a strike replacement company that
    contained a minimum shift guarantee, nor that it failed to bargain over the impacts of such a
    decision. Again, we do not see how this consideration leads to a conclusion the test the
    Board announced was clearly erroneous in light of its duties under the Act and its precedent.
    Instead, the County appears to be arguing the Board abused its discretion by imposing
    remedial orders beyond that which were alleged and litigated. We will address this
    30
    argument post; but, as far as the County’s attempt to demonstrate the Board’s test is
    erroneous, we are unpersuaded.
    C
    The Board’s Determination The County Unlawfully Prohibited Members From Using Paid
    Leave For The Three Days After The Strike Was Not Clearly Erroneous
    The County contends the Board clearly erred by finding its refusal to allow members
    to use paid leave for days they were barred from returning to work constituted
    discrimination and interference because there is no evidence the County did so based on
    protected activity. To the contrary, the County argues, it treated the three days after the
    strike as it would any other time an employee did not work a scheduled shift.
    We note the County does not analyze this issue under the well-established
    discrimination or interference standards. Instead, it offers what it believes to be
    contradictions in the Board’s reasoning without citation to authority or analysis as to how
    the Board’s reasoning fails to meet the well-established standards. “To demonstrate error,
    appellant must present meaningful legal analysis supported by citations to authority and
    citations to facts in the record that support the claim of error. [Citations.] When a point is
    asserted without argument and authority for the proposition, ‘it is deemed to be without
    foundation and requires no discussion by the reviewing court.’ [Citations.] Hence,
    conclusory claims of error will fail.” (In re S.C. (2006) 
    138 Cal.App.4th 396
    , 408.)
    In any event, the Board found the County both interfered with and discriminated
    against protected activity when denying use of paid leave for the three days following the
    strike. To establish a prima facie interference case, a charging party must show an
    employer’s conduct tends to or does result in some harm to union or employee rights
    protected by the Act. Importantly, the charging party does not need to show an improper
    motive. (City of San Diego, supra, PERB Dec. No. 2747-M at p. 36.) Thus, as far as an
    interference claim is concerned, the County’s argument the Board erred because no
    evidence demonstrated the County denied paid leave based on Nurses’ and members’
    31
    exercise of protected rights fails at the outset. The County’s prohibition against the use of
    accrued leave by striking members for the three days following the strike resulted in striking
    members not being paid, despite a willingness to work, for more than twice as long as
    members had anticipated. This harmed Nurses’ and members’ protected rights because it
    discouraged future striking activity by expanding the risk involved in striking beyond the
    control of those participating in the strike as described ante. There was no need to
    demonstrate the County’s acts were motivated by Nurses’ and members’ exercise of
    protected rights, and we fail to see how the County’s practice in other contexts is relevant to
    how it treated striking employees differently following the strike.
    Similarly, a finding of discrimination is not dependent on a showing the County’s
    conduct was motivated by a discriminatory intent. Indeed, if an employer’s conduct facially
    discriminates based on protected activity, it constitutes “ ‘discrimination in its simplest
    form,’ ” and the Board may thus infer unlawful discrimination without further evidence of
    motive. (Los Angeles Superior Court, supra, PERB Dec. No. 2566-C at p. 14.) The
    Culberson memo explicitly prohibited striking members from returning to work for three
    days after the strike and the County then refused to allow those members to use accrued
    time to offset the lost time at work. The County did not target nonstriking members in the
    days following the strike in the same way; some of the nonstriking members chose not to
    work because the essential worker injunction was no longer in effect.
    Further, the evidence did not establish the County was prevented from offering
    members the use of accrued leave. In fact, the County permitted members to use accrued
    time when it prohibited them from working during scheduled shifts because of low patient
    census. The fact the memorandum of understanding provided for this type of furlough is of
    no consequence. Our focus is on the County’s actions in the face of members’ protected
    activity. (§ 3506.) Snyder’s and Culberson’s testimony establish the County’s only concern
    was paying for double staff. But Snyder testified accrued leave was already allocated to
    members and existed in a pot of money different from that which paid wages. In the only
    32
    other instance in which the County prohibited members from working scheduled shifts, the
    County offered members use of their accrued leave. The fact the County did not similarly
    do so in the days following the strike supports the Board’s determination the County’s
    prohibition was based on Nurses’ and members’ exercise of protected activity. Thus, the
    Board did not clearly err by finding a nexus between protected activity and the adverse
    action taken by the County. (See Novato Unified School District, supra, PERB Dec. No.
    0210-E at pp. 73-74.)
    III
    The Board’s Decision Is Supported By Substantial Evidence
    The County contends the Board’s decision is not supported by substantial evidence
    because no evidence supports its findings the County failed to make a good faith effort to
    negotiate for a contract with the least minimum shift guarantee and it discriminated against
    strike participants when offering available work following the strike. We disagree.
    The Board’s factual findings, which include credibility findings, are conclusive if
    substantial evidence on the whole record supports them. (See § 3564, subd. (c).) We do not
    reweigh the evidence but accept the Board’s reasonable inferences. (Boling v. Public
    Employment Relations Bd. (2018) 
    5 Cal.5th 898
    , 912-913.) Even if contrary findings may
    seem equally or even more reasonable than the Board’s findings, we uphold the Board’s
    decision as supported by substantial evidence if the Board’s findings are reasonable.
    (Regents of University of California v. Public Employment Relations Bd. (1986) 
    41 Cal.3d 601
    , 617.)
    A
    The Board’s Factual Finding The County Did Not Make A Good Faith Effort
    To Reduce The Minimum Shift Guarantee Is Supported By Substantial Evidence
    The Board determined “[t]he County did not establish that it made a good faith effort
    in the marketplace to negotiate a contract that would eliminate the minimum shift guarantee
    or shorten it to the greatest degree possible.” The Board based this finding on the County’s
    33
    inadequate efforts to collect bids from strike replacement companies, the lack of testimony
    supplied by the County demonstrating the industry standard regarding the length of
    minimum shift guarantees for strike replacement workers, and the County’s failure to
    negotiate the length of the minimum shift guarantee. The County argues insufficient
    evidence was presented at the administrative hearing to support the Board’s finding the
    County failed to collect a sufficient number of bids and failed to adequately negotiate the
    length of the minimum shift guarantee.8
    Addressing the County’s efforts to collect bids for strike replacement workers, the
    County argues the Board’s observation that the County had plenty of time before the strike
    to solicit bids from strike replacement companies penalized the County for planning ahead
    to protect its ability to provide patients with vital health services. Not so. The Board did
    not hold it against the County that it contracted with Healthsource in October 2019, long
    before the strike. The Board considered the four months the County searched for strike
    replacement companies between June and October 2019 and determined those four months
    were plenty of time in which to research and communicate with multiple strike replacement
    companies to find the best one to serve the County’s needs. The Board did not suggest the
    County should have taken longer or delayed entering into a contract until closer to the actual
    strike.
    The County also questions why the Board thought soliciting bids from three strike
    replacement companies was insufficient. The Board did not say soliciting bids from three
    strike replacement companies was insufficient. The Board thought the County’s solicitation
    8       The County also challenges the Board’s finding it “likely knew, or should have
    known, that [Nurses] and [the Service Employees Union] commonly hold strikes lasting
    fewer than five days at many California hospitals.” We do not address this challenge
    because the Board did not consider this fact as evidence the County did not act in good faith.
    It considered this fact to question “why the County failed to negotiate over the minimum
    shift guarantee before executing a replacement contract.” It is this latter consideration that
    supported the Board’s lack of good faith finding, and it is this consideration we review.
    34
    of the three companies at issue was insufficient. Indeed, Maxim was not a strike
    replacement company and the County was having problems with Maxim’s services at the
    time it requested a bid for strike replacement workers. The evidence on this point supports
    the Board’s finding the County never seriously entertained Maxim as an option, and thus the
    County did not adhere to its own policy of obtaining three quotes before contracting with a
    strike replacement company.
    As a practical matter, the County solicited a bid from a prohibitively expensive strike
    replacement company and a company with whom it had negotiated in the past. The County
    was unaware of any other options in the marketplace and presented no evidence pertaining
    to the contents of a typical contract with a strike replacement company for the Board to
    compare to the County’s ultimate contract. While the County was unaware of the
    particulars of the Board’s new test, it was aware it would need to justify its decision with a
    legitimate business reason or business necessity. (See Campbell Municipal Employees
    Assn. v. City of Campbell, supra, 131 Cal.App.3d at p. 423.) As discussed ante, and
    contrary to the County’s argument here, this requirement does not negate the importance of
    the County’s considerations when contracting with a strike replacement company, but
    instead balances its efforts with the impacts its decision had on members who exercise
    protected activity. The County has raised no arguments undermining the Board’s finding
    the County made inadequate efforts to collect bids from strike replacement companies and
    has presented no evidence regarding the industry standard pertaining to minimum shift
    guarantees.
    Addressing the County’s failure to negotiate a shorter minimum shift guarantee, the
    County disputes the Board’s finding that “ ‘[h]ad the County negotiated in a timely manner
    to change the [minimum shift guarantee] as it sought to change other contract terms, it is
    more likely than not that [Healthsource] would have reduced the minimum period in order
    to secure the County’s business.’ ” First, the County contends it tried to negotiate a lesser
    minimum shift guarantee. The Board agreed the County tried to negotiate a lesser minimum
    35
    shift guarantee; however, the Board’s issue was that the attempt to lower the contractual
    term happened after the County had already entered into a contract with Healthsource
    containing a five-shift minimum guarantee. At that point, the County’s bargaining power
    had already been reduced and Healthsource had no incentive to agree to a different term
    than the term already in the contract. This finding, and the reasonable inference regarding
    bargaining power flowing therefrom, are supported by Snyder’s testimony she did not
    negotiate the substance of the contract with Healthsource until after selecting Healthsource
    for the strike replacement contract.
    The County also contends there was no evidence Healthsource would have agreed to
    a lower minimum shift guarantee given Elbahou’s testimony the five-shift guarantee was
    Healthsource’s standard term. But Elbahou’s had no knowledge of other contracts entered
    into by Healthsource and he was not involved in many of the negotiations with the County.
    The Board took administrative notice of other Healthsource contracts demonstrating
    Healthsource had agreed to lower minimum shift guarantees, and the County does not argue
    the administrative notice was taken in error. The evidence demonstrated Healthsource had
    negotiated lower minimum shift guarantees in the past and may have done so again if the
    County had raised the issue before agreeing to enter into a contact with Healthsource. The
    County argues the context of the other contracts is much different than the one entered into
    with the County. But the County did not supply any evidence on that point, as it was
    required to do as the party bearing the burden of proving the affirmative defense. (Great
    Dane, supra, 388 U.S. at pp. 33-34 [18 L.Ed.2d at pp. 1034-1035].) Instead, it called
    Elbahou to testify and his knowledge was lacking as to the context of the other contracts.
    Accordingly, sufficient evidence supports the Board’s finding the County failed to establish
    it made a good faith effort to enter into a contract containing as short a minimum shift
    guarantee as possible in light of maintaining critical health care services.
    36
    B
    The Board’s Factual Finding The County Discriminated Against Strike Participants When
    Offering Available Work Is Supported By Substantial Evidence
    The Board found the County preferred nonstrikers over strikers when filling available
    work opportunities after the strike based on the County’s admissions and deviation from
    established practices to offer full-time nurses work opportunities before other types of
    nurses. The County disputes this finding, arguing it never admitted or stipulated it treated
    striking members differently than nonstriking workers and there was no evidence pertaining
    to the County’s established practices. We disagree.
    The evidence established the County filled striking members’ shifts during the two-
    day strike with strike replacement workers, traveling nurses, and essential employee
    members enjoined from striking. When the strike was over and members attempted to work
    their scheduled shifts, Culberson told members the shifts were filled and that members were
    not needed to fill shifts. It was not until essential employees enjoined from striking refused
    to work, because they were no longer under an order to do so, that the County attempted to
    fill available work opportunities with striking members. But work opportunities not covered
    by strike replacement workers were available after the strike, the County just kept in place
    the nonstriking members and traveling nurses it had relied on during the strike. The County
    stipulated to this fact and admitted as much during testimony. Based on these admissions,
    we need not address the County’s argument the call-off order for low census furloughs
    contained in the memorandum of understanding did not constitute the County’s established
    practice. Accordingly, sufficient evidence supports the Board’s finding the County
    preferred nonstriking workers to fill available work opportunities following the strike.
    IV
    The Board’s Chosen Remedy Was Not An Abuse Of Discretion
    The County contends the Board imposed an overbroad and punitive remedy by
    ordering the County to pay members for the period of time they were barred from work, and
    37
    to offer this pay structure in the future. The County raises several arguments in this regard:
    that it should not be required to pay members who were offered work opportunities during
    the three days after the strike but refused to return to work; that the Board’s remedy of
    providing the use of accrued leave contradicts the rule it announced that the County bargain
    over the impacts of a minimum shift guarantee that lasts longer than a planned strike; that
    the remedy does more than make members whole because, as the Board acknowledged,
    members’ absences were not due to low patient census, making vacation pay unavailable in
    the first instance; and that Nurses never alleged the County committed an unfair practice by
    failing to negotiate the impacts of a delayed return-to-work schedule, thus it was outside the
    Board’s authority to remedy an unalleged violation. We disagree.
    The Board “has broad powers to remedy a violation of the Act. ([Citations]; see
    § 3509, subd. (b) [‘The initial determination as to whether the charge of unfair practice is
    justified and, if so, the appropriate remedy to effectuate the purposes of [the Act], shall be a
    matter within the exclusive jurisdiction of [the Board] . . . .’]; see also § 3541.3, subd. (i) . . .
    ; § 3541.3, subd. (n) . . . .)” (Boling v. Public Employment Relations Bd. (2019) 
    33 Cal.App.5th 376
    , 387 (Boling II).)
    The Board also has “the power to issue [an] . . . order directing an offending party to
    cease and desist from the unfair practice and to take such affirmative action, including but
    not limited to the reinstatement of employees with or without back pay, as will effectuate
    the policies of this chapter.” (§ 3541.5, subd. (c); see also Cal. Code Regs., tit. 8, § 32325
    [“The Board shall have the power to issue a decision and order in an unfair practice case
    directing an offending party to cease and desist from the unfair practice and to take such
    affirmative action . . . as will effectuate the policies of the applicable statute”].)
    We review the Board’s remedial orders for abuse of discretion. (Boling II, supra, 33
    Cal.App.5th at p. 387.) “Generally, a ‘remedial order “should stand unless it can be shown
    that the order is a patent attempt to achieve ends other than those which can be fairly said to
    effectuate the policies of the Act.” [Citations.]’ ([Citations]; Jasmine Vineyards, Inc. v.
    38
    Agricultural Labor Relations Bd. (1980) 
    113 Cal.App.3d 968
    , 982 . . . [‘[i]t is only when the
    remedies ordered by the Board are patently outside the Board’s authority that a reviewing
    court can interfere’].) [¶] Nonetheless, [the Board’s] remedial orders may not be punitive.
    [Citation.] They may not violate the separation of powers doctrine. [Citation.] And, they
    may not encroach upon statutes and policies unrelated to the Act and, therefore, outside of
    [the Board’s] competence to administer.” (Boling II, supra, 33 Cal.App.5th at pp. 387-388.)
    The Board’s order that the County allow members to use accrued leave, even if those
    members refused to return to work when ordered to do so, was not an abuse of discretion.
    The Board grounded this decision in the particular facts of the case, leading us to conclude
    the decision was not guided by punitive intentions. When attempting to return to work,
    members inquired whether Culberson had invoked the furlough process outlined in the
    memorandum of understanding. Culberson testified he was not clear and misspoke. He also
    testified he never told members they were not being furloughed pursuant to the
    memorandum of understanding. Given this misunderstanding, the Board justifiably treated
    members who refused to return to work similar to members who were never requested to
    return to work.
    The Board imposed the remedy of allowing members to use accrued leave based on
    the County’s discriminatory prohibition against it and the County’s discriminatory policy
    instituting a delayed return-to-work schedule. As discussed, ante, these determinations were
    not clearly erroneous. Accordingly, the use of paid leave makes members whole in the
    sense it puts them in the position they expected to be in when notifying the County of the
    two-day strike. Indeed, this remedy actually benefits the County in that sense because it
    pulls upon a pot of money already allocated to members instead of forcing the County to
    pay the wages members expected to make when notifying the County of the strike.
    The Board’s order to permit members to use accrued leave in similar future
    situations, unless the parties agree otherwise, was also not an abuse of discretion. The
    County argues this remedy contradicts the Board’s newly announced rule that it will bargain
    39
    over the impacts of a minimum shift guarantee. We disagree because the Board’s order is
    specific to the County and Nurses and their established practices and not applicable to all
    labor disputes involving all health care providers. The County treated members differently
    after the strike than it treated them in the only other similar situation in which members are
    prohibited from working when they are otherwise able and willing to work -- furloughs due
    to low patient census. The County argues the Board erred because the fact members can use
    accrued leave in the event of the low patient furloughs was a bargained-for perk specific to
    times when the Hospital has a low patient census. But the County has not pointed to any
    other circumstance where members are told not to work a scheduled shift through no fault of
    their own and then denied pay and the use of accrued leave. Indeed, several members
    testified that it was their understanding that whenever they are prevented from working a
    scheduled shift but are willing to work, they consider it a “furlough” and are permitted to
    use accrued leave. Thus, the only reason members would not be permitted to use accrued
    leave under the circumstances present here is because members exercised their protected
    right to strike. That is discrimination in its purest form (Los Angeles Superior Court, supra,
    PERB. Dec. No. 2566-C at p. 14), and the Board acted within its authority to prevent the
    County from engaging in discriminatory practices in the future.
    Finally, it is of no concern that Nurses did not allege the County committed an unfair
    practice by failing to bargain over the impacts of a delayed return-to-work schedule. The
    fact the County did not attempt to lessen the impacts of a delayed return-to-work schedule
    was subsumed in Nurses’ allegations the County discriminated against and interfered with
    protected activity by threatening and implementing a delayed return-to-work schedule and
    by penalizing members for not working scheduled shifts when the failure to work was
    outside of their control. The Board’s remedial order remedies the discrimination and
    interference resulting from these adverse actions, which could have been lessened by notice
    and negotiations over impacts, and the Board did not need to ground its orders in a separate
    failure-to-bargain finding.
    40
    V
    The Board Did Not Err By Applying Its Newly Announced Test Retroactively
    The County contends the Board’s newly announced test should not have been applied
    retroactively because the County relied on settled and persuasive National Labor Relations
    Board decisions finding contracts with strike replacement companies containing minimum
    shift guarantees to be conduct that is comparatively slight and justifying delays in
    reinstating workers. We disagree.
    “ ‘As a general rule, judicial decisions are given retroactive effect, even if they
    represent a clear change in the law. [Citation.] The exception is when considerations of
    fairness and public policy are so compelling in a particular case that, on balance, they
    outweigh the considerations that underlie the basic rule. [Citation.] This exception applies
    in particular when a party justifiably has relied on the former rule.’ ” (Bearden v. U.S.
    Borax, Inc. (2006) 
    138 Cal.App.4th 429
    , 442.)
    As the County points out, the Board has no settled rule regarding contracts with
    strike replacement companies. Indeed, the Board has never decided whether an employer’s
    conduct in contracting with a strike replacement company requiring a minimum shift
    guarantee constitutes inherently destructive or comparatively slight conduct. Even with its
    decision here, the Board did not determine that such conduct always constitutes inherently
    destructive conduct, but instead determined the inquiry was highly factual and dependent on
    the totality of an employer’s conduct and considerations when hiring a strike replacement
    company. The County asserts it looked to persuasive authority when entering into a
    contract and it was unforeseen that the Board would diverge from that persuasive authority.
    The County’s assertions are disingenuous considering the multiple instances in which the
    Board has diverged from National Labor Relations Board decisions. (See, e.g., City of San
    Jose v. Operating Engineers Local Union No. 3, supra, 49 Cal.4th at p. 611; Fremont
    Unified School Dist., supra, PERB Dec. No. 1054-E at pp. 10-11; County of Trinity (United
    Public Employees of California, Local 792), supra, PERB Dec. No. 2480-M at p. 3.) Thus,
    41
    the County has not shown a reasonable reliance on the National Labor Relations Board rule,
    and the Board did not err by applying its newly-announced test retroactively.
    DISPOSITION
    The Board’s decision is affirmed. The parties shall bear their own costs.
