    OPINION
    ¶1     Petitioner, the International Brotherhood of Teamsters, Local 700 (Union), appeals from
    a decision and order of the Illinois Labor Relations Board, Local Panel, that upheld two general
    orders issued by respondents, the County of Cook and the Sheriff of Cook County. In relevant
    No. 1-15-2993
    part, the first general order—known as the Gang Order—prohibits employees from associating
    with anyone the employee knew or should have known is or was in a gang and requires
    employees to complete a disclosure form about gang affiliations. The second general order—
    known as the Rules of Conduct Order—provides in part that the rules for on- and off-duty
    conduct extend to social media and networking sites. On appeal, the Union contends that the
    Gang Order was a subject of mandatory bargaining and the social media policy in the Rules of
    Conduct Order is overbroad under section 10(a)(1) of the Illinois Public Labor Relations Act
    (Act) (5 ILCS 315/10(a)(1) (West 2012)). We reverse the Board’s decision as to the Gang Order
    and affirm the Board’s decision as to the Rules of Conduct Order.
    ¶2                                           I. BACKGROUND
    ¶3       During the relevant time period, the Union was the exclusive representative of the
    Correctional Officers, Deputy Sheriffs, and Fugitive Investigators bargaining units. 1 The Gang
    Order and Rules of Conduct Order, which applied to employees of the Cook County Sheriff’s
    Office (CCSO), were issued on January 18, 2013, and had effective dates of January 25, 2013.
    The Gang Order (order number 11.2.21.0) has eight sections that are marked with roman
    numerals. Sections I-IV are not directly at issue, but parts of those sections provide helpful
    background. In relevant part, section II states that “[c]riminal organizations and street gangs pose
    a substantial threat to the public and directly impede the efforts of the CCSO to provide for
    public safety.” Section III provides in part that “[a]ny violation of this order may result in denial
    of access to the CCSO; disciplinary action up to and including termination; and/or criminal
    charges where applicable.” Beginning with section V, the Gang Order states:
    1
    Before the Board issued its decision, the Illinois Fraternal Order of Police Labor Council was allowed to
    intervene as the exclusive representative of the Deputy Sheriffs.

    ***” (Emphasis in original.)
    -5-
    No. 1-15-2993
    ¶4     The Gang Order includes an accompanying disclosure form. The form asks employees
    whether they were members of a Known Criminal Organization/Gang, if they had ever been
    members of a Known Criminal Organization/Gang, and for corresponding details. The form
    additionally asks, “Has any Family Relationship (as defined in the policy) or Associate ever been
    in a Known Criminal Organization/Gang Member or an Associate of a Known Criminal
    Organization within the past ten years?” The form again asks for corresponding details. At the
    bottom of the form is a space for the employee’s signature and the date, above which is written,
    “By signing below, I certify that the above information has been completed to the best of my
    knowledge.”
    ¶5     The second order at issue is the Rules of Conduct Order (number 11.2.20.0), which has
    seven sections that are marked with roman numerals. The Rules of Conduct Order states in part
    in section II that employees “shall conduct themselves in a professional and ethical manner both
    on and off duty.” Section VI of the order, which is the only section directly at issue, states in
    relevant part:
    “VI.      RULES AND REGULATIONS FOR ALL SWORN AND CIVILIAN CCSO
    EMPLOYEES
    ***
    B. Conduct on and off duty.
    CCSO employees shall:
    1.     Maintain a professional demeanor while on duty and will not
    engage in off-duty behavior that would reflect negatively on the
    CCSO.
    -6-
    No. 1-15-2993
    2.   Conduct themselves on and off-duty in such a manner to reflect
    favorably on the CCSO. Employees, whether on or off-duty, will
    not engage in conduct which discredits the integrity of the CCSO,
    its employees, the employee him/herself, or which impairs the
    operations of the CCSO. Such actions shall constitute conduct
    unbecoming of an officer or employee of the CCSO.
    3.   Be aware that conduct on and off duty extends to electronic social
    media and networking sites and that all rules of conduct apply
    when engaging in any Internet activity.
    4.   Maintain a level of conduct in their personal and business affairs
    that is in keeping with the highest standards of the law
    enforcement profession. Employees will not participate in any
    incident that:
    a.      Involves moral turpitude or impairs their ability to perform
    as law enforcement officers; or
    b.      Causes the CCSO to be brought into disrepute.
    5.   Not use their official position, official identification cards, stars or
    hat shields for:
    a.      Personal or financial gain for themselves or others.
    b.      Obtaining privileges not otherwise available to them except
    in the performance of duty.
    c.      Avoiding consequences of illegal acts.
    -7-
    No. 1-15-2993
    6.    Respect and be courteous to others and the public. Employees will
    be tactful in the performance of their duties, will control their
    tempers and exercise the utmost patience and discretion and will
    not engage in argumentative discussions even in the face of
    extreme provocation.
    7.    If sworn, carry CCSO credentials (e.g., Sheriff’s Photo
    Identification, County Identification, Firearm Owners
    Identification Card) on their person at all times except when
    impractical or dangerous to their safety or to an investigation; and
    make every effort to ensure the security and safekeeping of all
    identification, including star and hat shield.
    8.    Furnish their names and star numbers where applicable to any
    person requesting that information while on duty, unless
    withholding such information is necessary for the performance of
    police duties (e.g., undercover work).
    9.    Not use threats and coercion, or abusive, coarse, violent, profane,
    harassing, or insolent language or gestures.
    10.   Ensure that relationships with colleagues promote mutual respect
    within the profession and improve quality of service.
    11.   Utilize CCSO equipment only for its intended purpose and in
    accordance with the established procedures; shall not abuse or
    willfully damage CCSO equipment; shall use reasonable care to
    -8-
    No. 1-15-2993
    avoid loss of CCSO equipment; and shall maintain CCSO
    equipment in accordance with established procedures.
    12.     Not engage in any conduct that constitutes discrimination or
    harassment as defined in CCSO directives regarding
    discrimination, harassment, sexual harassment, and hostile work
    environment.”
    ¶6     The record contains email correspondence between Union representatives and
    respondents about the orders. On January 25, 2013, the Union’s attorney wrote an email to
    respondents with the subject line, “Sheriff Rules of conduct, 11.2.20.0 and 11.2.21.0.” The
    Union’s attorney demanded to bargain “over this proposed General Order” because it might
    affect wages, hours, and terms and conditions of employment. The Union’s attorney asked to
    advise when “such a meeting may be scheduled” and suggested that the meeting be held with
    “the pending request(s) for a DOC labor/management meeting.” Approximately 30 minutes later,
    an attorney for respondents replied, “Please see the newly issued Order referenced in your last
    email. If there is a particular area that you are concerned about that is in conflict with or departs
    from the predecessor to this Order ***, please let me know.” On February 12, 2013, the Union’s
    attorney sent respondents a letter that demanded to bargain over both orders.
    ¶7     On April 4, 2013, the Union filed a charge with the Board that respondents engaged in
    unfair labor practices related to the orders. The Union initially contended that both orders were
    unlawful unilateral changes to terms and conditions of employment without notice or the
    opportunity to bargain, though it later amended its position to maintain that only the Gang Order
    was a subject of mandatory bargaining. The Union additionally asserted in its charge that the
    -9-
    No. 1-15-2993
    Rules of Conduct Order contained overbroad restrictions on employee use of social media and
    networking sites.
    ¶8      On September 18, 2013, a hearing began before an administrative law judge (ALJ).
    Dennis Andrews, a Union business agent for the Cook County Department of Corrections,
    testified about the state of bargaining between the parties. Andrews stated that the Union did not
    receive a response to its email demand to bargain. Andrews further stated that he was involved in
    collective bargaining negotiations for the current Department of Corrections contracts, which
    began in January 2013. Andrews had attended each of the eight or nine bargaining sessions.
    According to Andrews, the orders were implemented before the first collective bargaining
    session, and neither the Sheriff nor the Union had raised either of the orders as a proposal at the
    bargaining table. Andrews stated that the Union had not raised the orders because it had
    demanded to bargain and the Sheriff had not responded with a proposal or meeting to discuss the
    orders. Andrews’s position was that if the Union demanded to bargain, it was up to the employer
    to respond. Andrews acknowledged that he did not have anything in writing from respondents
    that stated they would not bargain over the orders.
    ¶9      Andrews also testified about his interpretation of the Gang Order. He stated that before
    the Gang Order, neither he nor other officers had ever been required to complete a disclosure
    form for gang affiliations. Andrews described the paperwork as cumbersome and stated that the
    order required employees to investigate their family members and close associates. Andrews
    further stated that it was a lot of work for employees “to determine if their cousin that they
    haven’t seen in five years that lives in Iowa, or their sister who lives out in California,” fell into
    one of the named categories. According to Andrews, the disclosure requirement imposed a
    disciplinary burden, in that “if you are not sure, you don’t know and you don’t disclose it, then
    -10-
    No. 1-15-2993
    the Department comes to find out that maybe your brother-in-law was in a gang or is in a gang
    that you might not have knowledge of, you could be disciplined for not documenting that and
    giving them that information.” Andrews also stated that the Union found problematic the
    language that prohibits associating with anyone the employee “knew or should have known” is
    or was in a gang. Andrews asked, “What if it is your father, or your mother, sister?”
    ¶ 10   Andrews acknowledged that an October 1998 General Order for the Cook County
    Department of Corrections contained a provision stating, “No employee will frequent any
    establishment or knowingly associate with persons having known criminal records that would
    bring discredit to the department, except when properly authorized to do so.” Andrews also
    acknowledged that the October 1998 General Order contained a provision stating, “Employees
    will not visit any correctional institution for the purpose of visiting a detainee, inmate, or person
    incarcerated, not in their immediate family, without first submitting written notification to the
    divisional Superintendent/Unit Head. Immediate family includes: Father, Mother, Siblings and
    legal children (of the employee).” Andrews was also directed to a March 2001 General Order for
    the Court Services Department that directed employees to “avoid regular or continuous
    associations or dealings with persons whom they know, or should know, are persons under
    criminal investigation or indictment, or who have a reputation in the community or the
    department for present or past involvement in felonious or criminal behavior.” Andrews stated
    that the March 2001 order did not apply to the Department of Corrections and maintained that
    the Gang Order was the first time the “should have known” language was applied to Department
    of Corrections employees.
    ¶ 11   Asked to explain the benefits that the Union could bring to bargaining over the Gang
    Order, Andrews stated that the Union would raise its concerns about the possibility of discipline
    -11-
    No. 1-15-2993
    and the cumbersome paperwork and would ask respondents to “expound more upon what they
    really want in this and why they want it.” Andrews added that he would explain that the burden
    was on officers to investigate family members. Andrews further stated that the order was vague
    and did not inform employees of the ultimate goal.
    ¶ 12   Andrews also testified about the Union’s opposition to the social media provision in the
    Rules of Conduct Order. Andrews stated that there had not been any previous written work rules
    governing conduct on social media platforms. According to Andrews, the Union’s concern was
    that “you are constantly getting friended” on social media without knowing “how [a person]
    [conducts] themselves,” and an employee could be disciplined if that person was determined to
    be a known criminal, gang member, or former or released felon. Andrews further stated that the
    correctional officers have their own Facebook page “[s]o they can vent to each other” and “pass
    out information.” Andrews had seen complaints on the page about staffing levels. Andrews did
    not know of any employees who had been disciplined for statements made on the Facebook
    page. However, the administration monitored the page, and the Union was concerned that an
    employee could be disciplined “if somebody says the wrong thing on there or has a bad day at
    work *** and gets on the computer to vent.” Andrews further stated that the Rules of Conduct
    Order did not indicate exactly what employees could and could not do on social media.
    ¶ 13   John Figueroa, who was assigned to the Union as the chief steward for the Court Services
    Division, testified that the Union had demanded to bargain over the orders almost immediately
    after they were implemented, “if not the same day or the day after.” Meanwhile, collective
    bargaining negotiations for the Court Services Department were ongoing. Figueroa also stated
    that in his 25-year career with the Sheriff’s office, he had not been previously required to
    complete a disclosure form related to gang or criminal organization affiliations. Additionally,
    -12-
    No. 1-15-2993
    Figueroa testified that members of the Court Services Department engaged in criticism of
    workplace conditions on Facebook, such as complaining about inadequate elevators or criticizing
    staffing levels.
    ¶ 14    Kim Vargas, a Department of Corrections employee, testified that she was first required
    to complete a gang affiliation disclosure form in January 2013. Vargas further stated that she had
    been subjected to an Office of Professional Review interrogation related to the disclosure form.
    Vargas stated that she was “called in for the Sheriff’s Order that we were all supposed to fill out”
    and was notified that she did not properly complete it. Vargas completed an additional form and
    then was told to report for an accused investigation. Vargas believed that she could be suspended
    or lose her job, but had not yet been disciplined.
    ¶ 15    Respondents presented the testimony of Heather Bock, who worked in the Sheriff’s
    Office of Policy and Accountability and drafted the Gang Order. Bock stated that the Gang Order
    itself was new, but was not a new policy, as the provisions—apart from the signature on the
    form—could be found in previous orders. These older provisions stated that “[n]o employee will
    frequent any establishment or knowingly associate with persons having known criminal records
    that would bring discredit to the department, except when properly authorized to do so,” and
    “[e]xcept in the performance of official duties, or where unavoidable because of other family
    relationships, members will avoid regular or continuous associations or dealings with persons
    whom they know, or should know, are persons under criminal investigation or indictment, or
    who have a reputation in the community or the department for present or past involvement in
    felonious or criminal behavior.” However, Bock agreed that the Gang Order’s disclosure form
    was a new requirement.
    -13-
    No. 1-15-2993
    ¶ 16   As for the Rules of Conduct Order, Bock agreed that the statement, “Be aware that
    conduct on and off-duty extends to electronic social media” was new, but maintained that the
    basic rule was not really new. Bock asserted that the social media provision was a specific
    situation of on and off-duty conduct. Bock also stated that the orders did not change the kind of
    work that employees perform on a daily basis and consisted of “[j]ust filling out a form,” which
    employees do every day.
    ¶ 17   Peter Kramer, an attorney in the Sheriff’s office that handled labor matters, testified that
    the Sheriff had not refused to bargain over the two orders. Kramer asserted that “[e]verything is
    on the table” and that the Sheriff would be willing to bargain over the orders. Kramer was asked
    to recall instances where officers received corrective action because of gang or criminal
    affiliation. Kramer stated, “That happens all the time. Most frequently it involves officers
    bringing contraband into the facility, but there have been sporadic incidents.” Kramer noted an
    incident the previous month where a lieutenant traded inappropriate letters with a detainee and
    recalled that earlier in the year, an officer with a gang affiliation was shot. Kramer further stated
    that two or three months earlier, an officer was alleged to have “some gang affiliations, got in a
    bunch of trouble over like three different things.”
    ¶ 18   After the hearing, the parties submitted post-hearing briefs. In its brief, the Union
    clarified that its challenges to the Gang Order were the heightened opportunities for discipline
    from the disclosure form and the requirement that employees disclose all family and associates
    who may have been involved in criminal organizations, regardless of whether employees were
    aware of that involvement when they completed the form. The Union contended that the
    increased possibility for discipline made the new disclosure requirement a mandatory subject of
    bargaining. The Union further stated that respondents did not articulate any burdens to
    -14-
    No. 1-15-2993
    bargaining. Additionally, the Union asserted that respondents instituted the Gang Order without
    providing advance notice and an opportunity to bargain, despite the Union’s repeated and timely
    requests to do so. The Union further contended that the social media provision was overly broad,
    vague, and violated employees’ rights under section 10(a)(1) of the Act (5 ILCS 315/10(a)(1)
    (West 2012)).
    ¶ 19   In their brief, respondents asserted that the Sheriff is statutorily tasked with providing
    safety and security to employees and detainees and that gang affiliation with people detained in
    custody poses serious safety concerns. Respondents further stated that the issues of public safety,
    crime prevention, and correctional and courthouse security were within the inherent management
    authority and not subject to bargaining. Respondents contended that even if the orders affected
    wages, hours, and terms and conditions of employment, the public policies of preventing crime,
    citizen safety, and the security of jails and courthouses outweighed the Union’s interest in
    bargaining. Respondents also asserted that there had been problems with officers brought up on
    charges because of contact with felons or gang members, as well as incidents of officers bringing
    contraband into the jail. Respondents further stated that the Union’s complaint should be
    dismissed because bargaining was ongoing. Additionally, respondents contended that the social
    media provision did not impose new requirements on employees’ off-duty conduct.
    ¶ 20   The ALJ issued her decision on March 6, 2015, and agreed with the Union as to both
    orders. Applying the test for whether a matter is subject to mandatory bargaining that was
    outlined in Central City Education Ass’n v. Illinois Educational Labor Relations Board, 
    149 Ill. 2d 496
     (1992), the ALJ found that the Gang Order was a term and condition of employment
    because it subjected employees to potential discipline and employees could be barred from the
    premises for violating the order. The ALJ also found that the Gang Order involved a matter of
    -15-
    No. 1-15-2993
    inherent managerial policy, stating that that the Sheriff had a statutory duty to maintain safety
    and security within the County and the facilities under its control. After balancing the competing
    interests, the ALJ asserted that the benefits of bargaining over the Gang Order outweighed the
    burdens on respondents’ inherent managerial authority. The ALJ stated that the examples of
    problems given by respondents at the hearing were extremely vague and that respondents had not
    sufficiently demonstrated how bargaining over the Gang Order would significantly impact their
    ability to carry out their statutory duties. The ALJ stated that, in contrast, employees had a strong
    interest in bargaining over the Gang Order, noting that employees could be disciplined and
    barred from the premises under the order. The ALJ additionally found that respondents
    unilaterally imposed the Gang Order without bargaining to impasse. The ALJ stated that, at a
    minimum, respondents were required to give the Union adequate notice and a meaningful
    opportunity to bargain before implementing the policy, which they did not do.
    ¶ 21   Turning to the Rules of Conduct order, the ALJ found that the social media provision was
    unlawfully overbroad in violation of section 10(a)(1) of the Act (5 ILCS 315/10(a)(1) (West
    2012)). The ALJ asserted that the Board had not addressed whether a work rule that does not
    explicitly restrict protected activity could be unlawful, but the National Labor Relations Board
    (NLRB) had frequently addressed that issue. The ALJ further stated that the social media
    provision on its own did not prohibit any conduct and was instead a clarification that the conduct
    described in the conduct unbecoming provision applied to social media. As a result, according to
    the ALJ, the social media provision was overly broad if the conduct unbecoming provision was
    overly broad. Relying on NLRB decisions, the ALJ found that the conduct unbecoming
    provision was unlawful because it was not limited to unprotected activity and did not contain
    limiting language or any description of what was meant by conduct that would discredit
    -16-
    No. 1-15-2993
    respondents’ integrity. The ALJ stated that a reasonable employee could believe that the rule
    prohibits publicly criticizing the employer and its employment practices. The ALJ further stated
    that because the conduct unbecoming provision was overly broad, any application of the social
    media provision to the conduct unbecoming provision was also overly broad.
    ¶ 22   Subsequently, respondents filed exceptions in opposition to the ALJ’s recommended
    decision and order. In part, respondents contended that the issues of public safety, crime
    prevention, and correctional and court facility security were within their inherent authority and
    not subject to bargaining. Respondents cited several statutes that described their obligations and
    asserted that the legislature’s intent was to impose serious penalties to prevent interference with
    penal institutions such as the Cook County Department of Corrections. Respondents also
    contended that the Union did not present any rebuttal evidence that having officers with gang
    and criminal affiliation was not a serious problem. Additionally, respondents stated that the
    Rules of Conduct language at issue had been used by the Sheriff and numerous Illinois municipal
    agencies for decades and had become well-defined practice. Respondents further asserted that
    there was no evidence that the language had ever been used as the basis to discourage or
    discipline employees from engaging in protected activity. Lastly, respondents contended that the
    Sheriff had not refused to bargain and the Union had not raised the orders at the bargaining table.
    ¶ 23   On September 28, 2015, the Board issued a written decision that reversed the ALJ’s
    recommended decision and order. The Board found that respondents did not violate the Act
    “when they unilaterally implemented the Gang Order” because the Gang Order was not a
    mandatory subject of bargaining. The Board asserted that there was a self-evident connection
    between “dealing with the widespread gang problem, in order to address [respondents’] mandate
    to provide safety and keep the peace” and “having current and accurate information about and/or
    -17-
    No. 1-15-2993
    proscribing the gang membership and related associations with persons having gang affiliations.”
    The Board also referred to section 5 of the Illinois Streetgang Terrorism Omnibus Prevention Act
    (740 ILCS 147/5 (West 2012)), which stated that areas throughout Illinois were being “terrorized
    and plundered by streetgangs” and that streetgangs’ activities “present a clear and present danger
    to public order and safety and are not constitutionally protected.” The Board added that it was
    aware of the “well-publicized and staggering number of violent crimes” in and around Chicago,
    as well as “the ongoing and inextricable connection between violent crime and gang activity.”
    The Board further stated that it recognized that the threat of gang violence, gang activity, and
    gang influence was magnified in an environment such as the Cook County Jail and other places
    where respondents are mandated to provide safety and keep the peace. The Board found that the
    Gang Order was “clearly a matter of inherent managerial authority” and the balance weighed
    significantly in favor of respondents’ managerial rights.
    ¶ 24   Turning to the Rules of Conduct Order, the Board found that the conduct unbecoming
    rule had existed in predecessor General Orders since at least 1998 and that its substantive
    essence had not been changed simply because respondents advised employees that the same
    proscription applied to conduct carried out by contemporary means of communication. The
    Board asserted that the ALJ’s analysis “overlooks the critical fact that the conduct proscribed,
    has been proscribed, in essentially the same ‘conduct unbecoming’ terms since at least 1998.”
    The Board could not find any evidence in the record to suggest that the Union had previously
    challenged the conduct unbecoming rule and stated that the Union could not point to any
    instance in the long life of the conduct unbecoming rule when the employer had punished an
    employee for exercising protected rights. The Board stated that under these circumstances, a
    reasonable employee would not be justified in the belief that the rule morphed into a prohibition
    -18-
    No. 1-15-2993
    on publicly criticizing the employer and its employment practices or that the rule otherwise
    tended to interfere with or coerce employees in the exercise of the right to engage in protected
    activity.
    ¶ 25    One Board member dissented as to the Gang Order, disagreeing with the Board’s finding
    that the burden of bargaining outweighed its benefits. The dissenting Board member recognized
    respondents’ need to limit employees’ association with gang members, but found that the
    evidence was insufficient to establish that requiring respondents to bargain over the Gang Order
    would impair their ability to carry out their statutory mission. According to the dissenting Board
    member, respondents introduced little evidence to show that employees’ associations with gangs
    had suddenly become urgent to the point that bargaining would be a significant burden on
    respondents’ inherent managerial rights. The dissenting Board member stated that the Gang
    Order imposed significant new responsibilities and that bargaining might have increased the
    chances that those responsibilities would have been more clearly defined and reasonable.
    ¶ 26    The Union subsequently appealed.
    ¶ 27                                    II. ANALYSIS
    ¶ 28                                    A. Gang Order
    ¶ 29    On appeal, the Union first contends that respondents violated sections 10(a)(1) and
    10(a)(4) of the Act (5 ILCS 315/10(a)(1), 10(a)(4) (West 2012)) by failing and refusing to
    bargain over the Gang Order. The Union argues that the “should have known” language and
    disclosure requirement constitute changes to the terms and conditions of employment. The Union
    further asserts that the Gang Order involves heightened opportunities for discipline. The Union
    also maintains that the Gang Order does not involve inherent managerial authority, but that if it
    does, the benefits of bargaining outweigh the burdens. The Union contends that through
    -19-
    No. 1-15-2993
    bargaining, the Union could help formulate and clarify the Gang Order, as well as assist
    respondents in meeting their objectives. The Union also states that respondents did not articulate
    any burdens to bargaining.
    ¶ 30   “The issue of whether a public employer is required to bargain over a specific subject
    generally involves a mixed question of law and fact,” which warrants a clearly erroneous
    standard of review. Forest Preserve District of Cook County v. Illinois Labor Relations Board,
    
    369 Ill. App. 3d 733
    , 751 (2006). We will reverse the Board’s decision only where, on the entire

    ¶ 31   Turning to the applicable statutes, sections 10(a)(1) and 10(a)(4) of the Act state in part:
    “(a) It shall be an unfair labor practice for an employer or its agents:
    (1) to interfere with, restrain or coerce public employees in the
    exercise of the rights guaranteed in this Act or to dominate or interfere
    with the formation, existence or administration of any labor organization
    or contribute financial or other support to it *** [or]

    -20-
    No. 1-15-2993
    (4) to refuse to bargain collectively in good faith with a labor
    organization which is the exclusive representative of public employees in
    an appropriate unit, including, but not limited to, the discussing of
    grievances with the exclusive representative[.]” 5 ILCS 315/10(a)(1),
    (a)(4) (West 2012).
    ¶ 32    Section 7 of the Act states that a public employer and the exclusive representative of the
    public employees have the duty to bargain collectively “over any matter with respect to wages,
    hours and other conditions of employment.” 5 ILCS 315/7 (West 2012). However, employers are
    not required to bargain over matters of “inherent managerial policy,” which include “such areas
    of discretion or policy as the functions of the employer, standards of services, its overall budget,
    the organizational structure and selection of new employees, examination techniques and
    direction of employees.” 5 ILCS 315/4 (West 2012). It is possible for a matter to be both one of
    wages, hours, and other conditions of employment and within an employer’s inherent managerial
    authority. Central City, 
    149 Ill. 2d at 523
    . Faced with these scenarios, Central City set out a test
    to determine whether a matter is a subject of mandatory bargaining.

    v. Illinois State Labor Relations Board, 
    181 Ill. 2d 191
    , 206 (1998) (applying the Central City
    test to cases arising under the Act). Under the Central City test, a matter is a mandatory subject
    of bargaining if it (1) involves wages, hours, and terms and conditions of employment and (2) is
    either not a matter of inherent managerial authority or (3) is a matter of inherent managerial
    authority but the benefits of bargaining outweigh the burdens bargaining imposes on the
    employer’s authority. Central City,

    369 Ill. App. 3d at 752.
    -21-
    No. 1-15-2993
    ¶ 33   A matter concerns wages, hours, and terms and conditions of employment if it (1)
    involved a departure from previously established operating practices, (2) effected a change in the
    conditions of employment, or (3) resulted in a significant impairment of job tenure, employment
    security, or reasonably anticipated work opportunities for those in the Union. Chicago Park
    District v. Illinois Labor Relations Board, 
    354 Ill. App. 3d 595
    , 602 (2004). Further, a rule that
    subjects employees to potential discipline concerns the terms and conditions of employment. See
    County of Cook, 347 Ill. App. 3d at 552 (because residency requirement subjected employees to
    potential discipline, requirement affected employees’ terms and conditions of employment).
    ¶ 34   The Gang Order has two components at issue—the “should have known” requirement
    and the disclosure requirement. We consider whether each component concerns the terms and
    conditions of employment. The Sheriff maintains that the “should have known” language is not
    new, and points to a previous Court Services order that stated that employees were to “avoid
    regular or continuous associations or dealings with persons whom they know, or should know,
    are persons under criminal investigation or indictment, or who have a reputation in the
    community or the department for present or past involvement in felonious or criminal behavior.”
    The Sheriff also refers to a previous General Order that stated, “No employee will ***
    knowingly associate with persons having known criminal records that would bring discredit to
    the department, except when properly authorized to do so.”
    ¶ 35   The Sheriff overlooks key differences between previous orders and the Gang Order. The
    Gang Order states that an employee may not associate with anyone who the employee “knew or
    should have known *** is or was a member of a Known Criminal Organization.” Even if the
    “should have known” language was in a previous order, the Gang Order re-defined the category
    of people with whom an employee may not associate. While the previous orders prohibited
    -22-
    No. 1-15-2993
    associating with people who had criminal records, were under criminal investigation or
    indictment, or had a particular reputation, the Gang Order prohibits associating with people who
    are members of a group with certain traits—namely, the group forms an allegiance for a common
    purpose, engages in criminal activity, and does one or more of the following: shares a common
    group name, shares common symbols, tattoos, or graffiti, shares a common style of dress,
    frequently congregates upon, or lays claim to, a geographic location, and associates together on a
    regular or continuous basis. Moreover, the Gang Order has a broader sweep. Now, to be
    someone with whom the employee may not associate, a person need not have personally engaged
    in criminal activity or have a reputation for doing so, but need only to have been part of a group
    that does. Further, the Gang Order states that “[a]ny violation of this order may result in denial of
    access to the CCSO; disciplinary action up to and including termination; and/or criminal charges
    where applicable.” Because employees are subject to potential discipline for associating with a
    new category of people, the “should have known” requirement concerns the terms and conditions
    of employment.
    ¶ 36   The disclosure requirement also amounts to a change that affects the terms and conditions
    of employment. Under the Gang Order, employees must disclose “any and all memberships and
    associations” and states that “[f]ailure to disclose a relevant membership or association is a
    violation of CCSO policy.” Refusal to complete information or falsifying information on the
    disclosure form results in “[d]isciplinary action up to and including termination.” The Sheriff
    refers to the testimony of Heather Bock, who stated that the orders did not change the kind of
    work that employees perform on a daily basis and consisted of “[j]ust filling out a form,” which
    employees do every day. At the same time, Bock stated that the disclosure form was a new
    requirement, and Union witnesses testified that they had never had to disclose gang affiliations
    -23-
    No. 1-15-2993
    before. As with the “should have known” rule, the disclosure form requirement is a change that
    subjects employees to potential discipline, and therefore involves a change to the terms and
    conditions of employment. See id.
    ¶ 37   The next question is whether the Gang Order is also a matter of inherent managerial
    authority, which has been defined as those matters residing “at the core of entrepreneurial
    control.” (Internal quotation marks omitted.) Board of Trustees of the University of Illinois v.
    Illinois Labor Relations Board, 
    224 Ill. 2d 88
    , 97 (2007) (quoting Ford Motor Co. v. National
    Labor Relations Board, 
    441 U.S. 488
    , 498 (1979)). As noted above, section 4 of the Act states
    that matters of inherent managerial policy include “such areas of discretion or policy as the
    functions of the employer, standards of services, its overall budget, the organizational structure
    and selection of new employees, examination techniques and direction of employees.” 5 ILCS
    315/4 (West 2012). It was not clearly erroneous to conclude that the Gang Order is a matter of
    the employer’s inherent managerial authority. The legislature has designated each sheriff as
    “conservator of the peace” in his county, who “shall prevent crime and maintain the safety and
    order of the citizens of that county.” 55 ILCS 5/3-6021 (West 2012). The Gang Order relates to
    preventing crime and maintaining safety—a function of the employer—and so is a matter at the
    core of respondents’ entrepreneurial control.
    ¶ 38   Moving to the next part of the Central City test, we must balance the benefits of
    bargaining against the burdens of bargaining on respondents. Relevant to this analysis,
    respondents presented testimony at the hearing about the extent of the gang problems among
    employees. Peter Kramer, a Sheriff’s office attorney, stated that officers receive corrective action
    because of gang or criminal affiliation “all the time,” but also stated that “there have been
    sporadic incidents.” Kramer recalled three incidents in the past year where employees’ gang
    -24-
    No. 1-15-2993
    affiliations had caused problems. For the Union’s part, Dennis Andrews testified that if the Gang
    Order were bargained, the Union would raise concerns about the paperwork and the possibility
    of discipline and would ask respondents to “expound more upon what they really want in this
    and why they want it.” Andrews expressed concern that employees could be disciplined for not
    disclosing gang affiliations of family members of which employees were not aware. Andrews
    was also concerned that employees would have to investigate their family members and close
    associates, and noted that it would be a lot of work for an employee to determine if his “cousin
    that [he] hasn’t seen in five years that lives in Iowa” or “[his] sister who lives out in California,”
    falls into one of the relevant categories.
    ¶ 39   Though we do not doubt Kramer’s testimony that gang affiliation among employees is a
    problem, the record does not indicate that this problem was so urgent that bargaining was not a
    possibility. Kramer noted three incidents in the past year and characterized the problems as
    “sporadic.” Further, the statute the Board relied on to reach its conclusion—the Illinois
    Streetgang Terrorism Omnibus Prevention Act (740 ILCS 147/5 (West 2012))—was made
    effective in 1993 and has not been amended since then. The evidence suggests that gang
    affiliations among employees have been an ongoing problem, but not that the problem had
    increased to the point where there was no time to bargain. Moreover, the parties were about to
    begin collective bargaining negotiations anyway when the new order was issued. But cf.
    American Federation of State, County & Municipal Employees, AFL-CIO v. Illinois State Labor
    Relations Board, 
    190 Ill. App. 3d 259
    , 263, 268 (1989) (in finding the burdens outweighed the
    benefits of bargaining a new drug testing policy, the court noted that the employer continued to
    find drugs in prison and drug use despite numerous measures, that as of spring 1988, officials
    were investigating 217 employees for possible drug dealing at the prison facilities, and that a
    -25-
    No. 1-15-2993
    survey revealed that 18% of trainees were involved with illegal drugs). See also Forest Preserve
    District of Cook County, 369 Ill. App. 3d at 753-54 (matter was subject of mandatory bargaining
    where the ALJ determined that the employer had time to bargain and that the employer’s
    asserted problems “were not so immediate that bargaining could not have occurred”). Further,
    and contrary to the Board’s assertion at oral argument, the Union indeed presented the benefits of
    bargaining, as well as highlighted areas of concern that bargaining could address. Andrews’s
    testimony indicates that bargaining could clarify the requirements of the disclosure form and
    what employees are actually tasked with, which would tailor the Gang Order to better meet
    respondents’ needs. Additionally, Union members have a significant interest avoiding the
    prohibited associations and completing the disclosure form correctly, as they could lose their
    jobs otherwise. See Town of Cicero v. Illinois Ass’n of Firefighters, IAFF Local 717, 
    338 Ill. App. 3d 364
    , 371 (2003) (Union members’ significant interest in the matter at stake was a
    consideration in the balancing analysis). We acknowledge that which matters are subject to
    mandatory bargaining and which are not are very fact-specific questions that the Board, given its
    experience, is eminently qualified to decide. Chicago Park District, 354 Ill. App. 3d at 602. At
    the same time, the clearly erroneous standard of review does not “relegate judicial review to
    mere blind deference of an agency’s order.” Board of Trustees of the University of Illinois, 
    224 Ill. 2d at 98
    . Under these circumstances, the Board’s conclusion was clearly erroneous, and the
    benefits of bargaining the Gang Order outweigh the burdens.
    ¶ 40   Having determined that the Gang Order was a subject of mandatory bargaining, we next
    consider whether respondents refused to bargain. The Union contends that it timely demanded to
    bargain the Gang Order, but no opportunity to bargain occurred. Meanwhile, the Sheriff asserts
    that he has not refused to bargain and that the Union has not raised the orders at the bargaining
    -26-
    No. 1-15-2993
    table. The Sheriff notes that the record does not contain evidence that the Sheriff ever stated in
    writing that he would not bargain. In its written decision, the Board appeared to agree that
    respondents unilaterally implemented the orders, having stated that respondents did not violate
    the Act “when they unilaterally implemented the Gang Order.”
    ¶ 41   When an employer has the duty to bargain, it must provide notice of its willingness to
    bargain before the time its plans are fixed. Service Employees International Local Union No. 316
    v. Illinois Educational Labor Relations Board, 
    153 Ill. App. 3d 744
    , 755 (1987). For its part,
    “[o]nce a union has been notified of a topic of bargaining, it must pursue bargaining.” 
    Id.
    ¶ 42   The record indicates that the Union fulfilled its obligation to pursue bargaining, but
    respondents failed to notify the Union they were willing to bargain before implementing the
    Gang Order. The Gang Order states that it was issued on January 18, 2013, and was effective on
    January 25, 2013. On January 25, 2013, the Union’s attorney sent an email that demanded to
    bargain and requested that the Gang Order and Rules of Conduct Order be held in abeyance. In
    their reply, respondents did not indicate that they were willing to bargain before implementing
    the Gang Order. The email response to the Union advised the Union’s attorney to “see the newly
    issued Order” and to let respondents’ attorney know if there was a particular area of concern. As
    an aside, the record does not disclose whether the Union was notified about the orders before
    January 25, but respondents do not contend that the Union’s demand to bargain was untimely.
    John Figueroa, one of the Union’s witnesses, testified that the Union demanded to bargain over
    the orders almost immediately after they were implemented, “if not the same day or the day
    after.” Returning to the matter at hand, despite the Union’s demand to bargain, respondents
    implemented the Gang Order. Kim Vargas, a Department of Corrections employee, testified that
    she had to complete a disclosure form in January 2013. Simply being willing to hear particular
    -27-
    No. 1-15-2993
    areas of concern was insufficient—respondents should have communicated a willingness to
    bargain in response to the Union’s demand. The Gang Order was presented as an impermissible
    fait accompli. See Chicago Transit Authority, 299 Ill. App. 3d at 944 (where correspondence
    from employer simply announced a job reclassification and changes in wage rates and stated that
    the employer would address questions, employer presented matter as a fait accompli and failed to
    bargain in good faith).
    ¶ 43   Because respondents refused to bargain the Gang Order—a subject of mandatory
    bargaining—in spite of the Union’s demand, they violated the Act.
    ¶ 44                                 B. Social Media Policy
    ¶ 45   Next, we consider the Union’s contention that the social media policy is overbroad and
    violates section 10(a)(1) of the Act (5 ILCS 315/10(a)(1) (West 2012)). The Union urges this
    court to adopt the ALJ’s reasoning and relies on advice memoranda from the General Counsel of
    the NLRB.
    ¶ 46   As the Union recognizes, Illinois courts have not yet addressed the issue of whether a
    social media policy—or any work rule, for that matter—violates section 10(a)(1) of the Act (5
    ILCS 315/10(a)(1) (West 2012)) because it is overbroad on its face. However, in labor cases, the
    rulings of the NLRB and federal courts that construe the National Labor Relations Act are
    persuasive authority for similar provisions in the Illinois Act. American Federation of State,
    County & Municipal Employees, Council 31 v. Illinois State Labor Relations Board, State Panel,
    
    216 Ill. 2d 569
    , 579 (2005). Further, our supreme court has recognized the close parallel between
    section 10(a) of the Act and section 8(a) of the National Labor Relations Act. City of Burbank v.
    Illinois State Labor Relations Board, 
    128 Ill. 2d 335
    , 345 (1989).
    ¶ 47   Section 10(a)(1) of the Act states in part:
    -28-
    No. 1-15-2993
    “(a) It shall be an unfair labor practice for an employer or its agents:
    (1) to interfere with, restrain or coerce public employees in the exercise of
    the rights guaranteed in this Act or to dominate or interfere with the
    formation, existence or administration of any labor organization or
    contribute financial or other support to it; provided, an employer shall not
    be prohibited from permitting employees to confer with him during
    working hours without loss of time or pay[.]” 5 ILCS 315/10(a)(1) (West
    2012).
    Additionally, section 6(a) of the Act states in part that employees are protected “in the exercise
    of the right of self-organization, and may form, join or assist any labor organization,” and have
    the right to “engage in other concerted activities not otherwise prohibited by law for the purpose
    of collective bargaining or other mutual aid or protection, free from interference, restraint or
    coercion.” 5 ILCS 315/6(a) (West 2012).
    ¶ 48   On the federal side, section 8(a) of the National Labor Relations Act states in part:
    “(a) Unfair labor practices by employer
    It shall be an unfair labor practice for an employer —
    (1) to interfere with, restrain, or coerce employees in the exercise of the
    rights guaranteed in section 157 of this title;
    (2) to dominate or interfere with the formation or administration of
    any labor organization or contribute financial or other support to it:
    Provided, That subject to rules and regulations made and published by the
    [NLRB] pursuant to section 156 of this title, an employer shall not be
    -29-
    No. 1-15-2993
    prohibited from permitting employees to confer with him during working
    hours without loss of time or pay.” 
    29 U.S.C. § 158
    (a) (2012).
    Moreover, section 7 of the National Labor Relations Act states in part that employees have the
    right to “self-organization, to form, join, or assist labor organizations” and to “engage in other
    concerted activities for the purpose of collective bargaining or other mutual aid or protection.”
    
    29 U.S.C. § 157
     (2012).
    ¶ 49   As for our standard of review, whether the social media policy violates section 10(a)(1)
    of the Act is a mixed question of law and fact—a question that examines the legal effect of a
    given set of facts (See Oleszczuk v. Department of Employment Security, 
    336 Ill. App. 3d 46
    , 50
    (2002)). As a result, we review the Board’s decision under the clearly erroneous standard,
    meaning that we will reverse the Board only when a review of the record leaves us with a
    “ ‘ “definite and firm conviction that a mistake has been committed.” ’ [Citation.]” 
    Id.
     Federal
    courts also use a deferential standard of review for NLRB decisions. See Guardsmark, LLC v.
    National Labor Relations Board, 
    475 F.3d 369
    , 374 (D.C. Cir. 2007) (stating that NLRB
    determinations are entitled to considerable deference as long as they are reasonably defensible
    and that the court defers to the NLRB’s interpretation of section 8(a) when the NLRB faithfully
    applies the applicable standard and adequately explains the basis for its conclusion); Community
    Hospitals of Central California v. National Labor Relations Board, 
    335 F.3d 1079

    (D.C. Cir. 2003) (stating that the court will affirm the NLRB’s order unless the NLRB acted
    arbitrarily or otherwise erred in applying established law to the facts of the case).
    ¶ 50   We are faced with a challenge to a rule’s existence, rather than a challenge to an
    employer’s enforcement of a rule. The NLRB has stated that to determine whether the mere
    maintenance of a rule violates section 8(a)(1) of the National Labor Relations Act, “the
    -30-
    No. 1-15-2993
    appropriate inquiry is whether the [rule] would reasonably tend to chill employees in the exercise
    of their Section 7 rights. Where the [rule is] likely to have a chilling effect on Section 7 rights,
    the [NLRB] may conclude that [its] maintenance is an unfair labor practice, even absent
    evidence of enforcement.” Lafayette Park Hotel, 
    326 N.L.R.B. 824
    , 825 (1998).
    ¶ 51    Subsequently, the NLRB expanded on the test for determining whether a rule is unlawful
    in Martin Luther Memorial Home, Inc., 
    343 N.L.R.B. 646
     (2004) (Lutheran Heritage). There,
    the NLRB distinguished between a rule that explicitly restricts protected activity and one that
    does not. A rule that explicitly restricts activity protected by section 7 of the National Labor
    Relations Act is unlawful. Id. at 646. If the rule does not explicitly restrict protected activity, the
    rule is unlawful under any of the following conditions: (1) employees would reasonably construe
    the language to prohibit protected activity; (2) the rule was promulgated in response to union
    activity; or (3) the rule has been applied to restrict the exercise of protected rights. Id. at 647. As
    additional considerations, the NLRB stated that it must give a challenged rule “a reasonable
    reading,” “must refrain from reading particular phrases in isolation, and *** must not presume
    improper interference with employee rights.” Id. at 646. Under the Lutheran Heritage
    framework, the validity of a workplace rule does not depend on “subjective employee
    understandings or actual enforcement patterns, but on an objective inquiry into how a reasonable
    employee would understand the rule’s disputed language.” Quicken Loans, Inc. v. National
    Labor Relations Board, 
    830 F.3d 542
    , 549 (D.C. Cir. 2016).
    ¶ 52    In its brief, the Board urges this court not to follow the framework set out in Lutheran
    Heritage. The Board also states that it did not address Lutheran Heritage in its decision and
    argues that Lutheran Heritage has been criticized, citing dissents from NLRB decisions.
    -31-
    No. 1-15-2993
    ¶ 53   As stated above, our own research has not revealed any Illinois cases that addressed
    whether the mere maintenance of a rule violated section 10(a)(1) of the Act. It is possible that
    Illinois courts have not been presented with a situation where Lutheran Heritage applies. In the
    federal setting, however, Lutheran Heritage has been followed in numerous decisions. See, e.g.,
    Boch Imports, Inc. v. National Labor Relations Board, 
    826 F.3d 558
    , 579 (1st Cir. 2016); Flex
    Frac Logistics, LLC v. National Labor Relations Board, 
    746 F.3d 205
    , 208-09 (5th Cir. 2014);
    International Union, United Automobile, Aerospace & Agricultural Implement Workers of
    America v. National Labor Relations Board, 
    520 F.3d 192
    , 197 (2d Cir. 2008); Guardsmark,
    LLC, 
    475 F.3d at 374
    ; Schwans Home Service, Inc., 364 N.L.R.B. No. 20 at *1 (2016); Valley
    Health System LLC, 363 N.L.R.B. No. 178 at *1 (2016); T-Mobile USA, Inc., 363 N.L.R.B. No.
    171 at *1 (2016); Hills & Dales General Hospital, 360 N.L.R.B. No. 70 (2014); Karl Knauz
    Motors, Inc., 
    358 N.L.R.B. 1754
    , 1754 (2012); Costco Wholesale Corp., 
    358 N.L.R.B. 1100
    ,
    1101 (2012); Albertson’s, Inc., 
    351 N.L.R.B. 254
    , 259 (2007). Lutheran Heritage has also been
    cited as additional authority in an Illinois Board decision, though it was in the context of a
    challenge to the enforcement of a work rule. Illinois Troopers Lodge No. 41, 30 PERI ¶ 70
    (ILRB State Panel 2013). Given Lutheran Heritage’s consistent application in federal cases and
    NLRB decisions, Lutheran Heritage applies here.
    ¶ 54   Furthermore, for all of the Board’s criticism of Lutheran Heritage in its brief, it has not
    provided an alternative framework for assessing where the mere maintenance of a rule is
    unlawful, without evidence of enforcement. The Board only points to dissents from NLRB
    decisions as instances where Lutheran Heritage has been criticized. The Board further asserts
    that the standard for section 10(a)(1) violations is whether the employer’s conduct, viewed
    objectively from an employee’s standpoint, reasonably tended to interfere with, restrain, or
    -32-
    No. 1-15-2993
    coerce employees in the exercise of activity protected under the Act. Yet, the Board’s support for
    that standard consists of cases where a union challenges an affirmative act by an employer, rather
    than the situation we are faced with here, where the Union asserts that merely maintaining the
    rule is unlawful. See Amalgamated Transit Union, Local 241, 30 PERI ¶ 9 (ILRB Local Panel
    2013); County of Woodford, 14 PERI ¶ 2017 (ISLRB 1998).
    ¶ 55   We next apply the Lutheran Heritage standard to the social media policy at issue. The
    Union argues that when read with the conduct unbecoming rule, the social media policy has an
    overbroad chilling effect on employee workplace-based speech on the Internet that violates
    section 10(a)(1) of the Act.
    ¶ 56   The conduct unbecoming rule states that employees shall:
    “2. Conduct themselves on and off-duty in such a manner to reflect
    favorably on the CCSO. Employees, whether on or off-duty, will not engage in
    conduct which discredits the integrity of the CCSO, its employees, the employee
    him/herself, or which impairs the operations of the CCSO. Such actions shall
    constitute conduct unbecoming of an officer or employee of the CCSO.”
    Immediately following is the social media policy, which states:
    “3. Be aware that conduct on and off duty extends to electronic social
    media and networking sites and that all rules of conduct apply when engaging in
    any Internet activity.”
    ¶ 57   The Union states that reading these provisions together, the social media policy prohibits
    conduct on electronic social media and networking sites that discredits the integrity of the
    CCSO, its employees, the employee him/herself, or which impairs the operations of the CCSO.
    Acknowledging that the social media policy does not explicitly prohibit protected activity, the
    -33-
    No. 1-15-2993
    Union asserts that the social media policy is unlawful under the first condition in Lutheran
    Heritage: employees would reasonably construe it to prohibit protected activity. Lutheran
    Heritage, 343 N.L.R.B. at 647. The Union contends that policy does not include limiting
    language or examples of what behaviors are prohibited. Of note, the Union does not maintain
    that the social media policy is unlawful under the other two possibilities stated in Lutheran
    Heritage—that the social media policy was promulgated in response to union activity or has
    been applied to restrict the exercise of protected rights. See id.
    ¶ 58   We find that the mere maintenance of the social media policy does not violate the Act.
    The Union may be correct that employees could interpret the social media policy to prohibit
    protected activity, but the possibility that employees could interpret the policy that way is not
    enough. Where the rule does not refer to protected activity, “we will not conclude that a
    reasonable employee would read the rule to apply to such activity simply because the rule could
    be interpreted that way.” (Emphasis in original.) Id. We reiterate that we must give the social
    media policy a reasonable reading and not read particular phrases in isolation. Albertson’s, Inc.,
    351 N.L.R.B. at 259. The social media policy is part of a set of three introductory rules of
    conduct that are followed by nine more specific rules. In context, the social media policy
    provides that all of the other, more specific rules of conduct—none of which are challenged
    here—apply to the Internet. The Union has not shown that applying the rules of conduct to
    Internet activity means that employees would construe the rules of conduct as prohibiting
    protected activity.
    ¶ 59   Further, the Union’s argument strongly relies on advice memoranda from the General
    Counsel of the NLRB, which are not persuasive authority. The General Counsel has final
    authority regarding investigations into unfair labor practices and prosecution of complaints
    -34-
    No. 1-15-2993
    before the NLRB. 
    29 U.S.C. § 153
    (d) (2012). In contrast, it is the NLRB that applies “the
    [National Labor Relations Act’s] general prohibitory language in the light of the infinite
    combinations of events which might be charged as violative of its terms.” Republic Aviation
    Corp. v. National Labor Relations Board, 
    324 U.S. 793
    , 798 (1945). While NLRB decisions are
    persuasive, the advice memoranda are not. Further, the Union did not present NLRB decisions or
    federal cases that suggest the social media policy is unlawful. The mere maintenance of the
    social media policy in the Rules of Conduct Order does not violate the Act.
    ¶ 60                                III. CONCLUSION
    ¶ 61   For the reasons stated above, respondents violated the Act by refusing to bargain the
    Gang Order. However, the social media policy is not overbroad and does not violate the Act. We
    reverse the Board’s decision as to the Gang Order and affirm the Board’s decision as to the
    social media policy in the Rules of Conduct Order.
    ¶ 62   Reversed in part; affirmed in part.
