    ____________________________________)
    This case involves the balance between an employee‟s right of
    informational privacy1 and a union‟s right to obtain information it needs to
    represent the employee in collective bargaining. The Service Employees
    International Union, Local 721 (SEIU) is the exclusive bargaining representative
    of all Los Angeles County (County) employees. The question here is whether
    SEIU is entitled to obtain the home addresses and phone numbers of all
    represented employees, including those who have not joined the union. We agree
    with both courts below that it is so entitled but reverse the Court of Appeal‟s
    imposition of procedural requirements limiting disclosure.

    , 372-373 (Pioneer Electronics).
    1
    State and federal labor decisions have long held that unions are
    presumptively entitled to contact information for all employees they represent.
    These decisions, and applicable labor laws, generally obligate the County to give
    SEIU the requested information. Whether the right to privacy under article I,
    section 1 of the California Constitution prohibits disclosure is a question of first
    impression. We conclude that, although the County‟s employees have a
    cognizable privacy interest in their home addresses and telephone numbers, the
    balance of interests strongly favors disclosure of this information to the union that
    represents them. Procedures may be developed for employees who object to this
    disclosure. However, the Court of Appeal exceeded its authority in this
    administrative mandate proceeding by attempting to impose specific procedures
    on the parties.
    I. BACKGROUND
    SEIU is the certified majority representative for County employees in
    several bargaining units. County employees have a collective right to unionize but
    an individual right to refuse to join or participate in a union. (Gov. Code, § 3502;2
    L.A. County Code, § 5.04.070.) To accommodate these rights, a public agency
    may enter into an “agency shop agreement” with the organization recognized as
    the employees‟ exclusive or majority bargaining agent. (§ 3502.5, subd. (a).) An
    “agency shop” is “an arrangement that requires an employee, as a condition of
    continued employment, either to join the recognized employee organization or to
    pay the organization a service fee . . . .” (Ibid.)
    Each of the County‟s bargaining units has a memorandum of understanding
    (MOU), with SEIU. Most of these MOUs have an agency shop provision that
    gives County employees four options: (1) join SEIU and pay dues; (2) decline to
    join and pay a fair share fee; (3) decline to join, object to the fair share fee, and
    2      All statutory references are to the Government Code unless otherwise
    specified.
    2
    instead pay an agency shop fee; or (4) decline to join, claim a religious exemption,
    and pay the agency shop fee to a nonreligious, nonlabor charitable fund. A
    recognized bargaining agent acts on behalf of all employees in a bargaining unit,
    whether the employees are union members or not.
    Teachers v. Hudson (1986) 
    475 U.S. 292
     (Hudson) requires that SEIU send
    County employees an annual notice to collect fees from nonmembers. The
    Hudson notice sets out membership options, applicable fees, and the reasons for
    these fees.3 SEIU‟s notice packet also includes forms allowing the employee to
    join or decline to join the union. Those who decline are asked to provide their
    name, home address, and home telephone number. Employees who do not return
    any form are, by default, considered “fair share fee payers.” As of 2007, nearly
    12,000 of the County‟s approximately 14,500 nonmember employees were fair
    share fee payers. SEIU has home addresses for about half of these nonmembers.4
    Historically, the County provided lists of nonmembers‟ names, worksites,
    office addresses, and supervisors, but has never given SEIU home addresses or
    telephone numbers. Consequently, SEIU has not sent Hudson notices directly to
    County employees. Instead, since at least 1994, SEIU has delivered Hudson
    notice packets to the Los Angeles County Employee Relations Commission
    (ERCOM), an independent body that manages relations between the County and
    3      In Hudson, the United States Supreme Court held that the First Amendment
    rights of nonunion employees require that, before an agency fee is collected,
    employees must receive “an adequate explanation of the basis for the fee, a
    reasonably prompt opportunity to challenge the amount of the fee before an
    impartial decisionmaker, and an escrow for the amounts reasonably in dispute
    while such challenges are pending.” (Hudson, supra, 475 U.S. at p. 310; see also
    Knox v. Service Employees Internat. Union, Local 1000 (2012) 567 U.S. __ [
    132 S.Ct. 2277
    , 2292-2293] [Hudson notice must also be provided when public-sector
    union imposes a special assessment or dues increase].)
    4     SEIU also has contact information for approximately 46,000 County
    employees who are members.
    3
    its employees under the Meyers-Milias-Brown Act (MMBA). (§§ 3507, 3509.)5
    ERCOM would then mail the Hudson notices, using address labels provided by
    the County.
    During negotiations in 2006, SEIU proposed amending the MOU as
    follows: “To facilitate the carrying out of this responsibility [to provide Hudson
    notices], each year the County shall furnish the Union with the names and home
    addresses of employees in [the] bargaining units covered by agency shop
    provisions.” SEIU also sought contact information for other reasons. As the
    exclusive bargaining representative, SEIU wanted to communicate with all County
    employees, members or otherwise, about union activities and events.6 It also
    wanted the information for recruitment7 and investigation of grievances.
    The County rejected the amendment, contending contact information was
    not relevant to any collective bargaining issue and disclosure would violate
    nonmembers‟ privacy rights. The County proposed either to continue the current
    arrangement or to negotiate a procedure for employees to release their own data.
    SEIU opposed these alternatives, withdrew its proposal to modify the Hudson
    notice provision, and filed a charge with ERCOM alleging an unfair employee
    relations practice.
    After a three-day hearing, an administrative hearing officer concluded the
    County‟s refusal to provide the contact information was an unfair labor practice.
    Relying on decisions by the Public Employment Relations Board (PERB) and the
    National Labor Relations Board (NLRB), the hearing officer held the contact
    information was presumptively relevant (see post, at p. 9) to SEIU‟s
    5      ERCOM performs the same function for Los Angeles County as the Public
    Employment Relations Board performs for other public employers in California.
    (See post, at p. 8.)
    6     Some communication with nonmembers is possible through bulletin boards
    at County worksites.
    7    A union representative testified: “If we had the chance to talk to [the non-
    members], we could have them as members.”
    4
    representation. While acknowledging that privacy interests were at stake, the
    hearing officer found the County had not met its burden to show that the
    nonmembers‟ privacy interest outweighed SEIU‟s need for the information.
    ERCOM adopted the hearing officer‟s findings and ordered disclosure.
    The County sought a writ of administrative mandate, urging that
    nonmembers had a constitutional privacy right that justified nondisclosure.8
    (Code Civ. Proc., § 1094.5.) Although the superior court concluded nonmember
    County employees had a legally protected privacy right and disclosure of their
    contact information constituted a “non-trivial” invasion of that right, it also held
    that SEIU needed the information to fulfill its duty to represent all County
    employees in collective bargaining. The court then balanced those competing
    interests. It observed that labor law precedents, while not dispositive, establish a
    strong public policy in favor of union access to the information. On balance, the
    public policy favoring collective bargaining outweighed any privacy interest
    nonmember County employees might have in nondisclosure. Because disclosure
    did not violate California law, the court denied the County‟s petition for relief
    from ERCOM‟s order.
    The County sought review, and the appellate court reframed the issue. It
    agreed with the trial court that nonmember employees had a reasonable
    expectation of privacy in their home addresses and phone numbers. However, the
    court did not balance this expectation of privacy against SEIU‟s need for the
    information. Instead, it characterized the question as whether a nonunion
    employee “has a reasonable expectation under California privacy laws that he or
    she will be provided notice and an opportunity to object before” contact
    information is disclosed to the union.
    8     The trial court held the privacy claim had not been exhausted because the
    County had not relied on it at the administrative hearing. Nevertheless, the court
    considered the claim on its merits.
    5
    The court acknowledged the question it framed was one of first impression.
    It sought guidance by analogizing SEIU‟s request to a class action discovery
    request for consumers‟ personal information. Importing a procedure from class
    action litigation, the court held nonmember employees were entitled to notice and
    an opportunity to opt out before their home addresses and telephone numbers
    could be disclosed to SEIU. (See, e.g., Pioneer Electronics, supra, 40 Cal.4th at
    pp. 372-373.) In this analysis, the appellate court assumed the privacy rights of
    objecting employees would always outweigh SEIU‟s need for the information and
    that SEIU only had a right to contact information for those nonmember employees
    who failed to object. We granted SEIU‟s petition for review.
    II. DISCUSSION
    A.     Employer’s Duty to Provide Information Relevant to Collective Bargaining
    As a threshold matter, apart from privacy concerns, the County contends no
    applicable law requires that it give SEIU the requested information. We hold to
    the contrary. Under the MMBA and applicable labor law precedents, the failure to
    provide relevant information violated the County‟s obligation to bargain in good
    faith. Before turning to the good faith question, we explore the interrelation
    between federal and state labor laws.
    1.     Overview of Applicable Labor Laws
    The National Labor Relations Act (NLRA) governs collective bargaining in
    private sector employment. (1 Castagnera et al., Termination of Employment
    (2002) § 1:131; see Department of Defense v. FLRA (1994) 
    510 U.S. 487
    , 503
    (Dept. of Defense); Teledyne Economic Development v. N.L.R.B. (4th Cir. 1997)
    
    108 F.3d 56
    , 59.) However, the NLRA leaves states free to regulate labor
    relationships with their public employees. (
    29 U.S.C. § 152
    (2); Davenport v.
    Washington Ed. Assn. (2007) 
    551 U.S. 177
    , 181.)
    Public employees in California do not have the right to bargain collectively
    absent enabling legislation. (American Federation of State etc. Employees v.
    County of Los Angeles (1975) 
    49 Cal.App.3d 356
    , 358 (American Federation).)
    6
    Rather than fashion a single overarching employment relations law, like the
    NLRA, our Legislature has passed several different statutes covering specific
    categories of public employees. (See Coachella Valley Mosquito & Vector
    Control Dist. v. California Public Employment Relations Bd. (2005) 
    35 Cal.4th 1072
    , 1084-86 (Coachella Valley).) In 1968, the Legislature enacted the MMBA,
    authorizing collective bargaining for employees of most local governments,
    including Los Angeles County. (§ 3500 et seq., added by Stats. 1968, ch. 1390,
    pp. 2725-2729.) State employees and those of school districts were excluded from
    the MMBA (Coachella Valley, at p. 1083), but separate statutes were later enacted
    to cover these government workers.9 “The MMBA imposes on local public
    entities a duty to meet and confer in good faith with representatives of recognized
    employee organizations, in order to reach binding agreements governing wages,
    hours, and working conditions of the agencies‟ employees. (Gov. Code, § 3505.)”
    (Coachella Valley, at p. 1083.)
    The MMBA is administered by PERB, a quasi-judicial administrative
    agency modeled after the NLRB. (See Coachella Valley, 
    supra,
     35 Cal.4th at
    pp. 1084-1085; § 3540.) Although the Legislature initially created PERB in 1975
    to enforce a different employment relations statute,10 PERB‟s jurisdiction has
    expanded as the Legislature passed new laws addressing specific realms of public
    9       Employment relations between the State of California and certain
    categories of its employees are governed by the Ralph C. Dills Act. (§ 3512 et
    seq., added by Stats. 1986, ch. 103, § 1, p. 237.) School district employment
    relations are covered by the Educational Employment Relations Act. (§ 3540 et
    seq.)
    10     The Legislature created the Educational Employment Relations Board
    (EERB) in 1975 to administer the Educational Employment Relations Act
    (EERA). (Coachella Valley, 
    supra,
     35 Cal.4th at pp. 1084-1085.) In 1977 the
    Legislature expanded the EERB‟s jurisdiction to encompass unfair practice
    charges under the State Employer-Employee Relations Act (§ 3512 et seq. [now
    the Ralph C. Dills Act]) and renamed the entity PERB. (Coachella Valley, at
    p. 1085.)
    7
    employment. (Coachella Valley, at p. 1085.) In 2000, the Legislature brought the
    MMBA within PERB‟s authority (Coachella Valley, at p. 1085; Stats. 2000,
    ch. 901, § 8, p. 6607 [adding § 3509]), giving PERB exclusive initial jurisdiction
    over complaints alleging unfair labor practices violating the MMBA. (§ 3509;
    City of San Jose v. Operating Engineers Local Union No. 3 (2010) 
    49 Cal.4th 597
    ,
    605.) However, the statute does not apply to Los Angeles County. (§ 3509,
    subd. (d).)
    In the same year the MMBA was enacted, the County passed its own
    ordinance conforming to the legislative policies expressed in the MMBA.
    (American Federation, supra, 49 Cal.App.3d at p. 358.) The ordinance created
    ERCOM to administer its provisions. (Ibid.; Los Angeles County Employees
    Assn., Local 660 v. County of Los Angeles (1973) 
    33 Cal.App.3d 1
    , 3.) In giving
    PERB jurisdiction over MMBA disputes, the Legislature made an express
    exception for ERCOM. Section 3509, subdivision (d) states that, notwithstanding
    PERB‟s jurisdiction to administer the MMBA, ERCOM retains the power to
    consider and resolve employment relations matters “consistent with and pursuant
    to the policies of this chapter.” Allegations of unfair labor practices by the County
    must be brought to ERCOM, not PERB. In essence, ERCOM is a separate agency
    empowered to resolve public employment labor disputes in Los Angeles County
    just as PERB does for all other counties in California.
    ERCOM must exercise its authority in a manner “consistent with and
    pursuant to” the policies of the MMBA as interpreted and administered by PERB.
    (§ 3509, subd. (d).) Accordingly, the County‟s ordinance must be construed to
    avoid any conflict with the MMBA, and decisions from PERB interpreting the
    MMBA are highly persuasive when interpreting the County‟s ordinance. As we
    discuss, PERB decisions have uniformly given unions the right to obtain employee
    home contact information. Federal administrative decisions interpreting
    analogous provisions of the NLRA are also persuasive authority supporting
    disclosure of the information sought here.
    8
    2.     Labor Law Precedents Hold Contact Information Presumptively
    Relevant
    Decisions under the NLRA and corresponding California laws have long
    held that employers must generally give unions the home addresses and telephone
    numbers of employees the union represents. These holdings stem from the general
    principle that an employer‟s duty to bargain in good faith encompasses an
    obligation to provide information the union needs in order to represent employees.
    The United States Supreme Court has observed, “There can be no question of the
    general obligation of an employer to provide information that is needed by the
    bargaining representative for the proper performance of its duties.” (NLRB v.
    Acme Industrial Co. (1967) 
    385 U.S. 432
    , 435-436, citing Labor Board v. Truitt
    Mfg. Co. (1956) 
    351 U.S. 149
    .)
    Some information is so intrinsic to the core of the employer-employee
    relationship that it is considered “presumptively relevant.” (Retlaw Broadcasting
    Co. v. N.L.R.B. (9th Cir. 1999) 
    172 F.3d 660
    , 669; San Diego Newspaper Guild,
    Local No. 95 v. NLRB (9th Cir. 1977) 
    548 F.2d 863
    , 867 (San Diego Newspaper
    Guild).) Presumptively relevant information must be disclosed unless the
    employer proves a lack of relevance or gives adequate reasons why the
    information cannot be supplied. (San Diego Newspaper Guild, at p. 867; The
    Kroger Company (1976) 
    226 NLRB 512
    , 513-514.)11 Moreover, in appropriate
    cases, a union‟s ability to obtain relevant information may be tempered by
    measures to accommodate privacy concerns. “Upon a clear showing of need for
    confidentiality, courts have found less than complete disclosure justified.
    [Citations.]” (Press Democrat, supra, 629 F.2d at pp. 1326-1327; see also Detroit
    Edison Co. v. NLRB (1979) 
    440 U.S. 301
    , 317-320.)
    11     Conversely, when the information requested is not ordinarily pertinent to
    collective bargaining, the union has the burden of establishing relevance. (Press
    Democrat Pub. Co. v. NLRB (9th Cir. 1980) 
    629 F.2d 1320
    , 1324 (Press
    Democrat); San Diego Newspaper Guild, supra, 548 F.2d at pp. 867-868.)
    9
    A union elected as an exclusive bargaining agent owes a duty of fair
    representation to all employees in the bargaining unit. (See Jones v. Omnitrans
    (2004) 
    125 Cal.App.4th 273
    , 283; Lane v. I.U.O.E. Stationary Engineers (1989)
    
    212 Cal.App.3d 164
    , 169; see also Vaca v. Sipes (1967) 
    386 U.S. 171
    , 177 [same
    rule under NLRA].) Accordingly, state and federal decisions have consistently
    held that the employer‟s obligation to provide relevant information extends to
    information about employees who are not union members.
    a.     NLRB Decisions
    The NLRB has held that employees‟ home addresses and phone numbers
    are presumptively relevant to the union‟s role as bargaining agent. (Harco
    Laboratories (1984) 
    271 NLRB 1397
    , 1398.) An evolving line of cases
    establishing this point began in 1966, just two years before the MMBA was
    enacted. In Excelsior Underwear, Inc. (1966) 
    156 NLRB 1236
    , 1239-1240, the
    NLRB ruled that private employers must provide unions with the names and
    addresses of all employees before an election to choose a bargaining
    representative. The NLRB reasoned that an employer can easily communicate
    with employees to oppose union representation, but labor organizers generally
    have limited access to worksites. Thus, without a list of employee names and
    addresses, labor unions cannot be certain of reaching all employees with
    arguments supporting representation. (Id. at pp. 1240-1241.) Although the union
    might have other means of communicating with some employees, these
    alternatives are not always adequate. The NLRB stressed that “the access of all
    employees to such communications can be insured only if all parties have the
    names and addresses of all the voters. . . . [B]y providing all parties with
    employees‟ names and addresses, we maximize the likelihood that all the voters
    will be exposed to the arguments for, as well as against, union representation.”
    (Id. at p. 1241, fn. omitted.) The United States Supreme Court later observed that
    the disclosure requirement established in Excelsior Underwear promotes the goal
    of fair elections “by encouraging an informed employee electorate and by
    10
    allowing unions the right of access to employees that management already
    possesses.” (NLRB v. Wyman-Gordon Co. (1969) 
    394 U.S. 759
    , 767.)
    Nearly 30 years ago, this court applied the Excelsior Underwear rule in the
    agricultural context. In Carian v. Agricultural Labor Relations Bd. (1984) 
    36 Cal.3d 654
    , we upheld a regulation requiring employers to provide a list of
    employee names, street addresses, and job classifications to a union seeking to
    organize agricultural employees. We noted that employers had long been required
    to furnish unions with lists of employee names and addresses under Excelsior
    Underwear and that facilitating communication between employees and union
    organizers aided the administration of union elections. (Carian, at pp. 665-667.)
    The Excelsior Underwear decision was later extended beyond the election
    context. In Prudential Insurance Company of America v. N.L.R.B. (2d Cir. 1969)
    
    412 F.2d 77
    , 81 (Prudential), the Second Circuit Court of Appeals held that an
    employer‟s duty of disclosure “applies with as much force to information needed
    by the Union for the effective administration of a collective bargaining agreement
    already in force as to information relevant in the negotiation of a new contract.
    [Citations.]” As the exclusive bargaining agent for all employees, a union has a
    statutory duty to represent the interests of nonmembers. (Humphrey v. Moore
    (1964) 
    375 U.S. 335
    , 342.) The Prudential court remarked, “It seems manifest
    beyond dispute that the Union cannot discharge its obligation unless it is able to
    communicate with those in whose behalf [it] acts.” (Prudential, at p. 84.) A
    union must be able to tell employees about negotiations and obtain their views on
    bargaining priorities. (Ibid.) “Further, in order to administer an existing
    agreement effectively, a union must be able to apprise the employees of the
    benefits to which they are entitled under the contract and of its readiness to
    enforce compliance with the agreement for their protection.” (Ibid.)
    The Prudential court observed that other types of information, such as
    wage data, are considered presumptively relevant. (Prudential, supra, 412 F.2d at
    p. 84.) It went on to conclude that employee contact information “has an even
    11
    more fundamental relevance” to the union‟s role. (Ibid.) The union needs contact
    information “to bargain intelligently on specific issues of concern to the
    employees. But data without which a union cannot even communicate with
    employees whom it represents is, by its very nature, fundamental to the entire
    expanse of a union‟s relationship with the employees. In this instance it is urgent
    so that the exclusive bargaining representative of the employees may perform its
    broad range of statutory duties in a truly representative fashion and in harmony
    with the employees‟ desires and interests. Because this information is therefore so
    basically related to the proper performance of the union‟s statutory duties, . . . any
    special showing of specific relevance would be superfluous.” (Ibid.)
    b.     PERB Decisions
    As noted, NLRA cases are persuasive authority for interpreting similar
    provisions of state law, including the MMBA. (Fire Fighters Union v. City of
    Vallejo (1974) 
    12 Cal.3d 608
    , 617; see also Los Angeles County Civil Service
    Com. v. Superior Court (1978) 
    23 Cal.3d 55
    , 63-64 [relying on NLRB precedent
    in construing MMBA provision regarding layoffs].) Based on Prudential and
    similar cases decided under the NLRA, PERB decisions have held that employee
    contact information is presumptively relevant under California‟s labor statutes and
    subject to disclosure upon a representative union‟s request.
    When such a request threatens to violate a constitutionally protected
    privacy interest, PERB decisions have also followed the NLRB in applying a
    balancing test. (Modesto Teachers Assn. (1985) PERB Dec. No. 479; Los Rios
    Classified Employee Assn. (1988) PERB Dec. No. 670; see Detroit Edison Co. v.
    NLRB, supra, 440 U.S. at pp. 317-320 [establishing the federal balancing test].)
    Once the union has established the relevance and need for certain information, the
    burden is on the employer to prove that disclosure would compromise the right of
    privacy. (Modesto Teachers Assn., at p. 10.) If the employer carries this burden,
    the court balances the conflicting interests of confidentiality and discovery. (Id. at
    pp. 11-13.) However, if the employer fails to show that disclosure would violate a
    12
    protected privacy interest, no balancing is necessary and the court will simply
    order the information disclosed. (Id. at p. 12.)
    In Stockton Unified School Dist. (1980) PERB Dec. No. 143 (Stockton), a
    school district refused to provide information about health insurance benefits paid
    to union members. Relying on NLRB cases, PERB ruled that a union is entitled to
    obtain all information necessary and relevant to representing employees in
    collective bargaining. (Id. at p. 22.) Because the health insurance information
    was presumptively relevant, the district‟s failure to provide it constituted a refusal
    to bargain in good faith under the EERA. (§ 3543.5; see Stockton, at pp. 18-19.)12
    Two years later, PERB extended Stockton to a request for employee addresses. In
    Mt. San Antonio Community College Dist. (1982) PERB Dec. No. 224 (Mt. San
    Antonio), a union sought home addresses of certain instructors who no longer
    worked for a community college district but were potentially entitled to benefits
    under a recent decision of this court. (Id. at p. 11.)13 The hearing officer
    concluded that the requested names and addresses were reasonably related to the
    union‟s representational duties. (Mt. San Antonio, at p. 11.) PERB agreed and
    ordered disclosure. (Id. at p. 12.)
    After Mt. San Antonio, PERB decisions have squarely held that the names
    and addresses of public employees are presumptively relevant and subject to
    disclosure as part of the duty to bargain in good faith. In Bakersfield City School
    Dist. (1998) PERB Dec. No. 1262 (Bakersfield), a union representing school
    district employees wanted their home addresses and telephone numbers to send
    Hudson notices and communicate with nonmembers about other collective
    12     The EERA is one of several public employment statutes administered by
    PERB. (Coachella Valley, supra, 35 Cal.4th at p. 1089.) Like the MMBA
    (§ 3505), the EERA requires public school employers to “meet and negotiate in
    good faith” with their employees‟ exclusive bargaining representatives. (§ 3543.5,
    subd. (c).)

    13
    bargaining issues. Alternate means of communication were not consistently
    reliable or confidential. (Bakersfield, at p. 15 [hearing officer‟s proposed
    order].)14 Citing Mt. San Antonio and NLRB decisions, PERB concluded the
    employee contact information was presumptively relevant to collective bargaining
    and the district‟s failure to provide it violated the EERA, both as a refusal to
    bargain in good faith (§ 3543.5, subd. (c)) and as an interference with the union‟s
    right to represent unit members (§ 3543.5, subd. (b)). (Bakersfield, at p. 22; see
    also San Bernardino City Unified School Dist. (1998) PERB Dec. No. 1270 at
    pp. 75-79.)
    These principles also apply to claims arising under the MMBA. In Golden
    Empire Transit Dist. (2004) PERB Dec. No. 1704-M (Golden Empire), a bus
    drivers‟ union requested employees‟ home addresses and phone numbers. The
    transit district refused, citing confidentiality concerns. (Id. at p. 2.) Instead, the
    district sent a consent form to all employees allowing them to agree to disclosure.
    Contact information would only be released to the union if the employee gave
    express permission. (Id. at pp. 2-3.) PERB concluded the district violated the
    MMBA (§§ 3503, 3505, 3506) by refusing to give the information “and by
    unilaterally changing the mechanics of providing such information” to the union.
    (Golden Empire, at p. 9.) Because a union‟s ability to communicate with those it
    represents is fundamental to its role in collective bargaining, employee contact
    information must be disclosed absent a compelling need for privacy. (Golden
    Empire, at p. 8.) The union‟s need for the information was strong. Its inability to
    communicate with employees in their homes had “severely hindered” the capacity
    to fulfill its obligations as their bargaining representative. (Id. at p. 7.) For
    example, the union could not advise employees of new union security
    requirements, dues increases, and workplace problems. (Ibid.) With home
    14     PERB adopted the hearing officer‟s findings of fact and conclusions of law
    as the decision of the board itself. (Bakersfield, supra, PERB Dec. No. 1262 at
    p. 2.)
    14
    address and telephone information, the union could directly inform employees
    about union meetings and negotiations and quickly contact employees who were
    potential witnesses in grievance investigations. (Ibid.) The union could not
    adequately communicate through alternate means, such as bulletin board postings
    or personal meetings at the jobsite, because the employees were bus drivers who
    worked different shifts and were frequently on the road. (Ibid.) The employer did
    not show that the need for privacy outweighed these substantial interests.
    While recognizing that PERB decisions “are due some deference,” the
    County asserts they are not persuasive because they draw upon precedents decided
    under the NLRA. As explained, however, federal authorities are relevant and
    properly examined for guidance in interpreting similar provisions in our state‟s
    labor laws. The Golden Empire analysis provides persuasive guidance here.
    Courts generally defer to PERB‟s construction of labor law provisions
    within its jurisdiction. (See San Mateo City School Dist. v. Public Employment
    Relations Bd. (1983) 
    33 Cal.3d 850
    , 856 [EERA]; Paulsen v. Local No. 856 of
    Internat. Brotherhood of Teamsters (2011) 
    193 Cal.App.4th 823
    , 830 [MMBA].)
    “PERB is „one of those agencies presumably equipped or informed by experience
    to deal with a specialized field of knowledge, whose findings within that field
    carry the authority of an expertness which courts do not possess and therefore
    must respect.‟ [Citation.]” (Banning Teachers Assn. v. Public Employment
    Relations Bd. (1988) 
    44 Cal.3d 799
    , 804.) We follow PERB‟s interpretation
    unless it is clearly erroneous. (Ibid.) Here, it is not. PERB‟s conclusion that the
    duty of good faith bargaining generally requires disclosure of employee contact
    information is consistent with the language and purpose of the MMBA, its own
    decisions interpreting it, and long-standing precedent under the NLRA. Nothing
    in the language or legislative history of the MMBA persuades us to upset this
    settled understanding.
    15
    3.     The MMBA Requires Disclosure of Contact Information
    The County makes several arguments to counter this analysis. None is
    availing. First, the County relies on two MMBA provisions to argue against
    disclosure.
    Section 3505 requires public employers to “meet and confer in good faith
    [with union representatives] regarding wages, hours, and other terms and
    conditions of employment . . . .” The statute states that the duty to meet and
    confer includes a duty to negotiate “to exchange freely information, opinions, and
    proposals, and to endeavor to reach agreement on matters within the scope of
    representation . . . .” (§ 3505.) The County asserts that the phrase “matters within
    the scope of representation” pertains only to the terms and conditions of
    employment and that employee addresses and phone numbers are not information
    that must be freely exchanged.
    Initially, the County‟s position is inconsistent with the language of the
    statute. The meet and confer duty requires parties “to exchange freely
    information . . . . and to endeavor to reach agreement on matters within the scope
    of representation . . . .” (§ 3505, italics added.) The phrase “matters within the
    scope of representation” describes the subjects on which the parties must seek
    agreement. It does not modify, or limit, the information that must be freely
    exchanged.
    Further, the County‟s narrow interpretation is not supported by precedent.
    It has long been held that “[o]ne aspect of the duty to bargain „collectively in good
    faith with labor organizations‟ [citation] requires the employer to make a
    reasonable and diligent effort to comply with the union‟s request for relevant
    information. [Citation.]” (Cardinal Distributing Co. v. Agricultural Labor
    Relations Bd. (1984) 
    159 Cal.App.3d 758
    , 762.) Doing so serves the MMBA‟s
    underlying policy of fostering informed collective bargaining. Accordingly,
    appellate courts have held that an employer‟s failure to provide such information
    constitutes a refusal to bargain in good faith. (Cardinal Distributing Co., at
    16
    p. 762.) The County argues the employee information at issue here is not relevant.
    Yet NLRB and PERB decisions undermine that assertion. (See, e.g., Bakersfield,
    supra, PERB Dec. No. 1262 at pp. 17-18.)
    The County next argues that another MMBA provision, section 3507, does
    not compel disclosure of employees‟ home addresses and phone numbers.
    Section 3507 lists several subjects on which a public employer may adopt rules to
    govern employment relations. Among these topics, the statute allows employers
    to adopt a rule for “[f]urnishing nonconfidential information pertaining to
    employment relations to employee organizations.” (§ 3507, subd. (a)(8).) Relying
    on the statutory construction canon expressio unius est exclusio alterius,15 the
    County argues that because a rule may be adopted for the furnishing of
    nonconfidential information, the Legislature must have intended to bar the
    disclosure of confidential information, including home addresses and telephone
    numbers. This assertion begs the next question we will address because it assumes
    the information is confidential. Moreover, PERB decisions interpreting the
    MMBA make it clear that section 3507 is not the source of the duty to disclose.
    Rather, a public employer‟s disclosure obligation arises from sections 3503,
    concerning unions‟ right to represent employees, and 3505, concerning employers‟
    obligation to bargain in good faith. (See Golden Empire, supra, PERB Dec.
    No. 1704-M at p. 19.)
    The County further contends the MMBA‟s legislative history shows that it
    was not intended to require the disclosure sought here. However, the County
    points to nothing in the legislative history that even mentions the issue. First, the
    County cites committee reports describing general opposition to codifying
    collective bargaining rules for public sector employees. But strong sentiments
    were also expressed in favor of collective bargaining (see, e.g., Assem. Interim
    15     This phrase means “[e]xpression of one thing is the exclusion of another.”
    (Black‟s Law Dict. (4th rev. ed. 1968) p. 692, col. 1; see Imperial Merchant
    Services, Inc. v. Hunt (2009) 
    47 Cal.4th 381
    , 389.)
    17
    Com. on Industrial Relations, Final Rep. on Assem. Bill No. 607 (1959 Reg.
    Sess.), and the MMBA was ultimately enacted.16
    Second, the County claims the legislative history demonstrates resistance to
    importing NLRA requirements into public sector collective bargaining.
    Specifically, one committee report observed that an amendment to the MMBA‟s
    “meet and confer” requirement was not intended to replicate the same procedure
    for collective bargaining in the private sector. (Assem. Com. on State
    Employment, Retirement, and Military Affairs, Summary of Major 1968
    Legislation (1967 Reg. Sess.).) Whereas good faith under the NLRA requires
    “sincere attempts by both sides to reach agreement,” the meet and confer provision
    of the MMBA was intended primarily to formalize and improve communications
    between the bargaining parties. (Assem. Com. on State Employment, Retirement,
    and Military Affairs, Summary of Major 1968 Legislation, p. 4.) The County cites
    this discussion as evidence that the Legislature did not intend to import all
    collective bargaining practices under the NLRA into the state law governing
    public employment relations. We need not resolve that question. Even if the
    County‟s interpretation is correct, it does not follow that the Legislature intended
    that California‟s courts and regulatory bodies ignore settled law under the NLRA
    when interpreting identical provisions in the MMBA. On the contrary, we have
    expressly approved of reference to the NLRA and cases interpreting it for
    guidance in construing our state‟s labor laws. (Fire Fighters Union v. City of
    Vallejo, supra, 12 Cal.3d at p. 617.) Nor does it follow that the Legislature
    intended to exempt public employers from the obligation to disclose employee
    contact information when the statutory language and legislative history of the
    MMBA are completely silent on the point.
    16     At the County‟s request, we have taken judicial notice of legislative
    materials for several bills, from 1959 through 1968, that the Legislature
    considered in enacting the MMBA.
    18
    Notably, the Legislature has expressly approved the disclosure of contact
    information for some public employees. Section 6254.3 creates an exception to
    the Public Records Act for state, school district, and county office of education
    employees. Under this statute, employees‟ home addresses and telephone
    numbers are generally exempt from public inspection, except that the information
    may be disclosed to “an employee organization pursuant to regulations and
    decisions of the [PERB]. . . .” (§ 6254.3, subd. (a)(3).)17 Accordingly, although
    the contact information for state employees and certain county and local
    employees is generally to be kept private from the public at large, the Legislature
    has specifically authorized its disclosure to unions in accordance with PERB
    precedent.18
    In a related point, the County asserts its conduct was appropriate under a
    local ordinance. The ordinance states, in relevant part: “To facilitate negotiations,
    the county shall provide to certified employee organizations concerned the
    published data it regularly has available concerning subjects under
    negotiation . . . .” (L.A. County Code, § 5.04.060, subd. A.) The County contends
    it had no obligation to disclose addresses and phone numbers because they were
    not published and do not concern a subject under negotiation. However, the
    agency charged with enforcing the ordinance concluded otherwise. The ERCOM
    hearing officer observed that the agency had never limited the information to be
    disclosed to the material described in the ordinance. The ordinance simply
    17    The statute makes an exception to this exception for law enforcement
    employees, whose home addresses and telephone numbers are not to be disclosed.
    (§ 6254.3, subd. (a)(3).)
    18    A regulation implementing this provision requires that the state provide
    employee unions with the home addresses of all represented employees. (Cal.
    Code Regs., tit. 8, § 40165.) Amicus curiae California Department of Personnel
    Administration states that it has provided home addresses to various employee
    unions in accordance with section 6254.3 since 1984.
    19
    describes a type of information the County must provide to the union; it does not
    purport to limit or prohibit additional disclosures.
    In any event, even if the County‟s interpretation of the ordinance were
    correct, it would have no effect because local rules cannot conflict with the
    MMBA. “The MMBA deals with a matter of statewide concern, and its standards
    may not be undercut by contradictory rules or procedures that would frustrate its
    purposes. [Citations.] Local regulation is permitted only if „consistent with the
    purposes of the MMBA.‟ [Citation.]” (International Federation of Prof. &
    Technical Engineers v. City and County of San Francisco (2000) 
    79 Cal.App.4th 1300
    , 1306.) Thus, the ordinance could not absolve the County of its broader duty
    under the MMBA to provide the information requested by the union.
    4.     Conclusion
    Consistent with PERB‟s long-standing interpretation of the MMBA and
    similar labor law provisions, SEIU‟s request for home addresses and phone
    numbers of the County employees it represented called for presumptively relevant
    information. The burden was therefore on the County to prove that the contact
    information was not relevant or to supply adequate reasons why the information
    could not be supplied. (San Diego Newspaper Guild, supra, 548 F.2d at p. 867;
    see also Modesto Teachers Assn., supra, PERB Dec. No. 479 at p. 10 [burden is
    on employer to show that disclosure would violate a right of privacy].) Because
    the County failed to do so, its refusal to provide the information violated the duty
    to meet and confer in good faith. (§ 3505; see Golden Empire, supra, PERB Dec.
    No. 1704-M at pp. 6-8; Bakersfield, supra, PERB Dec. No. 1262 at p. 22.)
    B.     Disclosure Does Not Violate the Constitutional Right of Privacy
    The foregoing analysis is based on settled labor law principles. Whether
    California‟s constitutional right of privacy requires a different resolution is a novel
    question.
    In 1972, Californians, by initiative, added an explicit right to privacy in the
    state‟s Constitution: “All people are by nature free and independent and have
    20
    inalienable rights. Among these are enjoying and defending life and liberty,
    acquiring, possessing, and protecting property, and pursuing and obtaining safety,
    happiness, and privacy.” (Cal. Const., art. 1, § 1, italics added.)
    In Hill v. National Collegiate Athletic Assn. (1994) 
    7 Cal.4th 1
     (Hill), this
    court established a framework for analyzing constitutional invasion of privacy
    claims. An actionable claim requires three essential elements: (1) the claimant
    must possess a legally protected privacy interest (id. at p. 35); (2) the claimant‟s
    expectation of privacy must be objectively reasonable (id. at pp. 36-37); and
    (3) the invasion of privacy complained of must be serious in both its nature and
    scope (id. at p. 37). If the claimant establishes all three required elements, the
    strength of that privacy interest is balanced against countervailing interests. (Id. at
    pp. 37-38.) In general, the court should not proceed to balancing unless a
    satisfactory threshold showing is made. A defendant is entitled to prevail if it
    negates any of the three required elements. (Id. at p. 40; see Pioneer Electronics,
    supra, 40 Cal.4th at p. 373.) A defendant can also prevail at the balancing stage.
    An otherwise actionable invasion of privacy may be legally justified if it
    substantively furthers one or more legitimate competing interests. (Hill, at p. 40.)
    Conversely, the invasion may be unjustified if the claimant can point to “feasible
    and effective alternatives” with “a lesser impact on privacy interests.” (Ibid.)
    The question in Hill was whether California Constitution article I, section 1
    supports a cause of action for invasion of privacy. Here, the question is somewhat
    different. The County claims it is obligated to assert employees‟ privacy rights
    and that this obligation relieves it of any duty to honor the union‟s requests.
    Nevertheless, Hill provides a useful framework for examining how competing
    interests are managed in the privacy context.
    “[I]n applying the Hill balancing test, trial courts necessarily have broad
    discretion to weigh and balance the competing interests. (Hill, supra, 7 Cal.4th at
    pp. 37–38.)” (Pioneer Electronics, supra, 40 Cal.4th at p. 371.) The trial court
    here found that County employees who are not union members have a substantial
    21
    interest in maintaining the privacy of their home addresses and telephone numbers.
    The court gave this interest additional weight because the employees had
    exercised their constitutional right not to associate with the union. However, on
    balance, the court concluded SEIU‟s interest in contacting the employees it
    represents “significantly outweighs” nonmembers‟ interest in preventing
    disclosure of the information. After examining each of the Hill factors, we agree
    with the trial court that disclosure was required.
    1.     Legally Protected Privacy Interest
    Legally recognized privacy interests include “interests in precluding the
    dissemination or misuse of sensitive and confidential information,” which Hill
    described under the umbrella term “ „informational privacy.‟ ” (Hill, supra, 7
    Cal.4th at p. 35.) The parties agree that County employees have a legally
    protected privacy interest in their home addresses and telephone numbers. “Courts
    have frequently recognized that individuals have a substantial interest in the
    privacy of their home. [Citations.]” (Planned Parenthood Golden Gate v.
    Superior Court (2000) 
    83 Cal.App.4th 347
    , 359.) In particular, the “privacy
    interest in avoiding unwanted communication” is stronger in the context of an
    individual‟s home than in a more public setting. (Hill v. Colorado (2000) 
    530 U.S. 703
    , 716.) Accordingly, home contact information is generally considered
    private. The next question is whether nonmember employees could reasonably
    expect that their contact information would be shielded from the union.
    2.     Reasonable, Although Reduced, Expectation of Privacy
    “A „reasonable‟ expectation of privacy is an objective entitlement founded
    on broadly based and widely accepted community norms.” (Hill, supra, 7 Cal.4th
    at p. 37.) The reasonableness of a privacy expectation depends on the surrounding
    context. We have stressed that “customs, practices, and physical settings
    surrounding particular activities may create or inhibit reasonable expectations of
    privacy.” (Id. at p. 36.)
    22
    The practice followed for many years in Los Angeles County contributed to
    a reasonable expectation of privacy. The County employs approximately 55,000
    people. Of this group, 14,500 employees have chosen not to join the union.
    Throughout the decades that SEIU has been the exclusive bargaining
    representative of these employees, the County has not given their home contact
    information to the union. Since 1994, the County and SEIU have used ERCOM,
    or a third party clearinghouse, to mail Hudson notices to nonmember employees.
    It is undisputed that the County has never disclosed the employees‟ home
    addresses or telephone numbers to the union. Considering this long-standing and
    consistent practice, it was reasonable for nonmember employees to expect that the
    County would continue to keep their home contact information private.
    Nonmember employees gave their home addresses and telephone numbers
    to the County for the limited purpose of securing employment. A job applicant
    who provides personal information to a prospective employer can reasonably
    expect that the employer will not divulge the information outside the entity except
    in very limited circumstances. For example, various laws require employers to
    disclose information to governmental agencies, such as the Internal Revenue
    Service and Social Security Administration, and disclosure may also be necessary
    for banks or insurance companies to provide employee benefits. (See Belaire-
    West Landscape, Inc. v. Superior Court (2007) 
    149 Cal.App.4th 554
    , 561
    (Belaire-West).) But beyond these required disclosures, it is reasonable for
    employees to expect that their home contact information will remain private “in
    light of employers‟ usual confidentiality customs and practices.” (Ibid.) The
    County followed its long-standing custom and practice when it refrained from
    disclosing the home addresses and telephone numbers of nonunion employees.
    Moreover, as the trial court observed, employees who exercised their right
    not to associate with the union have a somewhat enhanced privacy expectation.
    The record reflects that just over half of the approximately 14,500 nonmember
    employees voluntarily gave home contact information to SEIU when completing
    23
    their annual Hudson notice forms. The remaining 7,222 nonmember employees
    chose not to disclose this information, although in most cases they had numerous
    opportunities to do so.
    Both courts below determined that County employees had a reasonable
    expectation of privacy in their home addresses and phone numbers. For the
    reasons discussed, we agree. However, we note that the reasonableness of this
    expectation was somewhat reduced in light of the common practice of other public
    employers to give unions this information.
    Custom and practice can reduce reasonable expectations of privacy in
    information typically considered even more sensitive than addresses and phone
    numbers. In International Federation of Professional & Technical Engineers,
    Local 21, AFL-CIO v. Superior Court (2007) 
    42 Cal.4th 319
    , 327 (IFPTE), a
    group of reporters filed a Public Records Act (§ 6250 et seq.) request for the
    names, job titles, and gross salaries of City of Oakland employees earning over
    $100,000. We acknowledged that “many individuals, including public employees,
    may be uncomfortable with the prospect of others knowing their salary and . . .
    would share that information only on a selective basis, even within the
    workplace.” (IFPTE, at p. 331.) We also acknowledged that public disclosure of
    salary information could cause discomfort and embarrassment. (Ibid.)
    Nonetheless, we concluded the city‟s employees lacked a reasonable expectation
    of privacy in light of the Attorney General‟s long-standing opinion that
    government payroll information is public, the widespread practice of state and
    local governments to disclose this information, and the strong public policy
    favoring transparency in government. (IFPTE, at pp. 331-332, 338.)
    As in IFPTE, disclosure of employees‟ home contact information to their
    union “ „is overwhelmingly the norm.‟ ” (IFPTE, supra, 42 Cal.4th at p. 332.)
    For nearly 50 years, private employers have been required to disclose contact
    information to employees‟ unions. (See Prudential, supra, 412 F.2d at p. 84;
    Excelsior Underwear, Inc., 
    supra,
     56 NLRB at p. 1241.) Based on these federal
    24
    precedents, we remarked almost 30 years ago that requiring employers to furnish
    lists of employee names and addresses to facilitate communication with a union
    “is hardly novel in the arena of labor relations.” (Carian v. Agricultural Labor
    Relations Bd., supra, 36 Cal.3d at p. 665.) As discussed, PERB has held that the
    same disclosure rules apply to public employment under various California labor
    statutes, including the MMBA. (See Golden Empire, supra, PERB Dec.
    No. 1704-M, at pp. 6-8; Bakersfield, supra, PERB Dec. No. 1262, at p. 22.) Thus,
    when the information is requested, established precedent requires that all private
    employers and most public employers provide unions with contact information for
    all employees in the represented bargaining unit. Although we have concluded
    that, on balance, it was reasonable for County employees to expect that their
    information would not be disclosed to SEIU because of the long-standing practice
    in Los Angeles County, the reasonableness of this privacy expectation was
    reduced in light of the widespread, settled rules requiring disclosure elsewhere.
    (See Pioneer Electronics, supra, 40 Cal.4th at p. 372 [customers who had given
    their contact information to a manufacturer in connection with a product complaint
    had a “reduced” expectation of privacy].)
    3.     Serious Invasion of Privacy
    “Actionable invasions of privacy must be sufficiently serious in their
    nature, scope, and actual or potential impact to constitute an egregious breach of
    the social norms underlying the privacy right.” (Hill, supra, 7 Cal.4th at p. 37.)
    The disclosure contemplated in this case was more than trivial. It rose to the level
    of a “serious” invasion of privacy under Hill.
    In Dept. of Defense, 
    supra,
     
    510 U.S. 487
    , the Supreme Court considered a
    union request similar to the one SEIU makes here. The court observed: “Perhaps
    some of these individuals have failed to join the union that represents them due to
    lack of familiarity with the union or its services. Others may be opposed to their
    union or to unionism in general on practical or ideological grounds. Whatever the
    reason that these employees have chosen not to become members of the union or
    25
    to provide the union with their addresses, however, it is clear that they have some
    nontrivial privacy interest in nondisclosure, and in avoiding the influx of union-
    related mail, and, perhaps, union-related telephone calls or visits, that would
    follow disclosure.” (Id. at pp. 500-501, fn. & italics omitted.)
    In Pioneer Electronics, supra, 40 Cal.4th at pages 372-373, we found that
    disclosure of customer contact information to a class action plaintiff would not
    impose a serious invasion of privacy. There, however, the customers had already
    disclosed their contact information to the manufacturer when complaining about
    an allegedly defective product. The question was whether a second disclosure of
    that information to a class action plaintiff asserting the same complaint would
    constitute a serious invasion of privacy. (Ibid.) In finding it would not, we
    observed that the rules of civil discovery generally permit plaintiffs to discover
    contact information for potential class members in order to identify additional
    parties who might assist in prosecuting the case. (Id. at p. 373.) Courts of Appeal
    have regularly allowed the release of contact information sought in class action
    discovery. (See, e.g., Crab Addison, Inc. v. Superior Court (2008) 
    169 Cal.App.4th 958
    , 974; Lee v. Dynamex, Inc. (2008) 
    166 Cal.App.4th 1325
    , 1336-
    1338; Alch v. Superior Court (2008) 
    165 Cal.App.4th 1412
    , 1426-1427; Puerto v.
    Superior Court (2008) 
    158 Cal.App.4th 1242
    , 1245; Belaire-West, supra, 149
    Cal.App.4th at p. 562.) Indeed, “it is only under unusual circumstances that the
    courts restrict discovery of nonparty witnesses‟ residential contact information.”
    (Puerto v. Superior Court, supra, 158 Cal.App.4th at p. 1254.) The context here is
    different. The party seeking the information is a union the employees have chosen
    not to join and have declined in the past to give their contact information. Under
    these circumstances, disclosure to the union would create a more significant
    invasion of privacy than disclosure in the class action context.
    Moreover, the release of contact information contemplated in Pioneer
    Electronics would have occurred only after the customers had been given notice of
    the proposed disclosure and an opportunity to object. (Pioneer Electronics, supra,
    26
    40 Cal.4th at pp. 372-373.) These protections mitigated any privacy invasion
    caused by the disclosure.
    4.     Balancing of Interests Favors Disclosure
    Because the County made a sufficient showing on the essential elements of
    a privacy claim, we next consider whether the invasion of privacy is justified
    because it would further a substantial countervailing interest. (See Hill, supra, 7
    Cal.4th at p. 40.) “Invasion of a privacy interest is not a violation of the state
    constitutional right to privacy if the invasion is justified by a competing interest.
    Legitimate interests derive from the legally authorized and socially beneficial
    activities of government and private entities. Their relative importance is
    determined by their proximity to the central functions of a particular public or
    private enterprise. Conduct alleged to be an invasion of privacy is to be evaluated
    based on the extent to which it furthers legitimate and important competing
    interests.” (Id. at p. 38.) Here, the balance favors disclosure.
    SEIU‟s interest in obtaining residential contact information for all
    employees it represents is both legitimate and important. As discussed, a union
    elected as an exclusive bargaining agent owes a duty of fair representation to all
    employees in the bargaining unit it represents, including employees who are not
    union members. (See Jones v. Omnitrans, supra, 125 Cal.App.4th at p. 283.)
    A union breaches the duty of representation if it fails to inform employees
    about the status of negotiations (Kern High Faculty Assn. CTA/NEA (2006) PERB
    Dec. No. 1834) or changes in the contractual terms of their employment
    (Teamsters Local 896 (Anheuser-Busch) (1986) 
    280 NLRB 565
    , 575). Because
    the union‟s duty extends to all employees in the bargaining unit, regardless of
    union membership, the union must have the means of communicating with all
    employees on these important topics. In addition, a union must give nonmembers
    an opportunity to express their views on bargaining matters, even if these
    employees do not have a vote. (El Centro Elementary Teachers Assn. (1982)
    PERB Dec. No. 232.) Direct communication between unions and all bargaining
    27
    unit employees is essential to ensure that nonmembers‟ opinions are heard.
    Finally, as discussed, every year the union must send Hudson notices to all
    employees explaining how their dues are used. (Hudson, supra, 
    475 U.S. 292
    .)
    The obligation to send Hudson notices falls on the union, not the employer, and a
    union commits an unfair business practice if it collects an agency fee without
    providing a proper notice. (UPTE, CWA Local 9119 (2005) PERB Dec. No. 1784-
    H; see also Knight v. Kenai Peninsula Borough School Dist. (9th Cir. 1997) 
    131 F.3d 807
    , 817 [employer has no duty to ensure adequacy of union‟s Hudson
    notice].)
    Giving SEIU this contact information will not coerce employees into
    joining the union. An employee who chooses not to join a union still enjoys the
    benefits of union representation. “[T]here is a clear distinction between union
    membership and majority support for collective bargaining representatives.”
    (N.L.R.B. v. Wallkill Valley General Hosp. (3d Cir. 1989) 
    866 F.2d 632
    , 637.)
    Moreover, as several decisions on this subject have noted, alternative
    means for unions to communicate with nonmembers are often inadequate.
    Bulletin board postings may not meaningfully convey lengthy or complex
    information, and employers often monitor the materials posted. (Prudential,
    supra, 412 F.2d at pp. 81-82.) A posting provides only one-way communication
    and is not an avenue for unions to receive employees‟ views. (Id. at p. 82.) Other
    alternatives, such as union meetings and worksite visits by union representatives,
    are inefficient and ineffective means of communicating with large and dispersed
    groups of employees. (See Golden Empire, supra, PERB Dec. No. 1704-M, at
    p. 7.)
    In contrast, the privacy intrusion occasioned by disclosure of contact
    information to the union is reduced. As discussed, County employees‟ expectation
    of privacy is undermined by the common practice of disclosure in other settings.
    For decades, the NLRB has required private employers to furnish unions with
    employees‟ home contact information (see, e.g., Prudential, supra, 412 F.2d at
    28
    p. 84), and PERB has required most California public employers to make the same
    disclosure (see, e.g., Golden Empire, supra, PERB Dec. No. 1704-M, at pp. 6-8).
    The invasion of nonmember employees‟ privacy, while sufficiently serious to pass
    muster under the Hill test, is also comparatively mild. Nonmember employees
    may experience increased contact with the union by mail or other means (see
    Dept. of Defense, 
    supra,
     510 U.S. at pp. 500-501), but there is no evidence SEIU
    has ever engaged in any harassment of a nonmember. If harassment is a concern,
    employers may bargain for, or ERCOM may adopt, procedures that allow
    nonmembers to opt out and prevent disclosure of their contact information. (Cf.
    § 6254.3, subd. (b) [allowing certain employees to prevent disclosure of contact
    information by written request].) Although we have concluded that a balancing of
    interests generally favors disclosure, this balance might, in some cases, tip in favor
    of privacy when an individual employee objects and demands that home contact
    information be withheld.
    C.     Court May Not Impose Procedural Safeguards in a Mandate Proceeding
    A final question raised by the Court of Appeal‟s decision is the availability
    of what it termed “procedural safeguards,” giving employees the ability to object
    and prevent disclosure. The court below imposed a notice and opt-out procedure
    without balancing, or even considering, the union‟s interests in obtaining the
    requested information. In creating this procedure, the court expressly ignored
    labor decisions finding that unions are entitled to contact information and instead
    likened this case to the discovery of third party information in the class action
    context. Borrowing from Pioneer Electronics, supra, 
    40 Cal.4th 360
    , and other
    class action cases, the Court of Appeal held that nonmember employees had to be
    given notice and an opportunity to object before the County disclosed their contact
    information to SEIU.
    The parties here agree that the Court of Appeal overstepped its authority by
    ordering them to implement specific notice and opt-out procedures. Code of Civil
    Procedure section 1094.5, subdivision (f) expressly limits the remedies a court
    29
    may order when reviewing administrative orders and decisions. The court can
    deny the writ or grant it and set aside the decision. If it sets aside the decision, the
    court can order the agency to take further action, but it cannot “limit or control in
    any way the discretion legally vested in” the agency. (Code Civ. Proc., § 1094.5,
    subd. (f).) Here, rather than simply setting aside ERCOM‟s decision, the Court of
    Appeal directed the trial court to order: (1) that the County and SEIU meet and
    confer on a proposed notice for the trial court‟s review and approval; and (2) that
    the County send the approved notice to all nonmember employees. This
    disposition exceeded the court‟s codified authority because it stripped ERCOM of
    all discretion regarding the manner of disclosure. Further, implementation of the
    order would have required ERCOM to create new administrative procedures for
    resolving disputes over notice and opt-out rights.
    Although the Court of Appeal exceeded its authority by imposing a notice
    and opt-out requirement, other avenues for implementing privacy safeguards are
    available. Employers like the County remain free to bargain for a notice and opt-
    out procedure in negotiating collective bargaining agreements with employee
    unions. Public employers can also draft employment contracts that will notify
    employees their home contact information is subject to disclosure to the union and
    permit employees to request nondisclosure. Finally, nothing in the relevant
    statutes or case law appears to prohibit agencies such as PERB or ERCOM from
    developing notice and opt-out procedures that would allow employees to preserve
    the confidentiality of their home addresses and telephone numbers.19
    19      Such procedures have been developed in other public employment settings.
    For example, employees covered by the California Public Records Act can prevent
    release of their home addresses and telephone numbers by stating their objection
    in writing that they do not want this information disclosed to the union. (§ 6254.3,
    subd. (b); see Golden Empire, supra, PERB Dec. No. 1704-M, at p. 5; State
    Center Community College Dist. (2001) PERB Dec. No. 1471, at p. 5.)

    D.    Conclusion
    Long-standing case law and public policy support direct communication
    between unions and the employees they represent. On balance, we conclude
    SEIU‟s interest in communicating with all County employees significantly
    outweighs nonmembers‟ interest in preserving the privacy of their contact
    information.
    III. DISPOSITION
    The Court of Appeal‟s decision is reversed. The matter is remanded for
    entry of judgment denying the County‟s petition for writ of mandate.
