PERB Draws a Firm Line on Severance Petitions: Two Recent Decisions Confirm Limits on Transferring Employees to Existing Units and Strict Window-Period Rules

In two significant decisions issued weeks apart, the Public Employment Relations Board has provided clear and consequential guidance on the proper use of severance petitions under the Meyers-Milias-Brown Act and the Educational Employment Relations Act. In Fresno Unified School District (PERB Dec. No. Ad-531, July 28, 2025) and City and County of San Francisco (PERB Dec. No. Ad-532-M, August 27, 2025), PERB reaffirmed longstanding principles governing severance while rejecting attempts to use the procedure as a vehicle for transferring classifications from one existing bargaining unit into another. The decisions underscore the Board’s commitment to preserving bargaining-unit stability and enforcing the contract-bar doctrine and window-period requirements with precision.

In Fresno Unified, the International Association of Machinists and Aerospace Workers initially petitioned to sever the Roofers and Lead Roofers classifications from a larger building-trades unit represented by the Fresno Teachers Association. After the initial petition was deemed timely, the petitioner filed an amended petition seeking instead to place those classifications directly into an existing IAMAW-represented unit. 

In San Francisco, the San Francisco Deputy Sheriffs’ Association filed a severance petition seeking to remove Medical Examiner’s Investigators and Institutional Police Officers from Service Employees International Union Local 1021 units and place them into the DSA’s existing bargaining unit. When the Office of the General Counsel questioned the propriety of that approach, the DSA filed an amended petition proposing a new standalone unit consisting solely of the affected classifications. In both matters, the incumbent unions opposed the petitions, and PERB ultimately ruled against the petitioners’ attempts to achieve through amendment what the regulations do not permit.

The Board’s reasoning in each decision rests on the plain language and historical purpose of the severance regulations. Under PERB Regulation 33700 (applicable to EERA cases such as Fresno) and the parallel provisions governing MMBA cases, a severance petition is designed to create a new, standalone bargaining unit consisting exclusively of the employees being severed from a larger existing unit. The regulations do not authorize the transfer of employees or classifications from one represented unit into a different, already-established unit. PERB emphasized that the phrase “consisting of” in the regulatory text operates as a term of limitation, not an invitation to add employees to an unrelated unit. This interpretation aligns with decades of precedent distinguishing severance from unit-modification procedures and with the fundamental goal of the contract-bar doctrine: promoting stability in established bargaining relationships.

Equally important is the Board’s treatment of amendments filed outside the statutory window period. Both decisions confirm that a severance petition—or any amendment to such a petition—must be filed during the defined window period (the 29-day period beginning 120 days and ending 91 days before the expiration of the governing memorandum of understanding) whenever a memorandum of understanding is in effect. Material changes to the petition, such as shifting from an attempt to join an existing unit to the creation of a new standalone unit, cannot be treated as mere technical corrections. The Board rejected arguments that more general amendment provisions applicable to certification petitions override the specific timing restrictions imposed on severance petitions. In the San Francisco case, PERB expressly held that the more specific regulation governing severance controls. In Fresno Unified, the Board similarly concluded that the attempted amendment fundamentally altered the nature of the petition and therefore could not cure the original defect.

For California public safety unions, these rulings carry immediate and strategic significance. Deputy sheriffs’ associations, police officers’ organizations, and other safety-employee representatives frequently confront situations in which specialized classifications—such as institutional police, medical examiner investigators, or other public-safety-adjacent roles—may appear better suited to a dedicated safety-focused unit. The decisions make clear that severance is not a shortcut for reassigning such classifications to an existing unit. Instead, any effort to sever must be framed from the outset as the creation of a new, independent bargaining unit consisting solely of the employees being carved out. Unions contemplating such action must therefore conduct a thorough community-of-interest analysis demonstrating that the severed group shares distinct interests that cannot be adequately addressed within the larger unit. They must also time the filing precisely within the applicable window period and ensure that any subsequent amendments do not introduce material changes that would render the petition untimely.

The rulings also serve as a cautionary reminder about the perils of attempting to cure procedural defects through late amendments. Public unions should treat the window period as inviolate and should file only those severance petitions that are fully formed and compliant at the time of submission. Where an initial petition contains a fatal flaw, such as an improper request to transfer employees into an existing unit, the proper course is not to amend but to allow the defective petition to be dismissed and to refile a new, compliant petition when the next window period opens. This disciplined approach preserves credibility with PERB and avoids the risk of prolonged litigation over timeliness and procedural compliance.

Notwithstanding the procedural hurdles, these decisions do not foreclose legitimate severance efforts. The Board in Fresno Unified expressly remanded the matter for processing of the original petition, which had properly sought creation of a new standalone unit. Public safety unions may therefore continue to pursue severance where the facts support a distinct community of interest and where the procedural requirements are strictly observed. In appropriate cases, such petitions can strengthen representation for specialized safety classifications and enhance the ability of unions to address the unique concerns of their members.

Taken together, Fresno Unified and San Francisco reinforce PERB’s commitment to orderly representation processes and stable collective-bargaining relationships. Public unions would be well advised to review pending or contemplated severance initiatives in light of these holdings. By filing only fully compliant petitions within the prescribed window periods and by framing severance requests as the creation of new, standalone units, unions can protect their procedural rights and advance the interests of their members without inviting dismissal or protracted appeals. The decisions underscore the continuing importance of meticulous preparation and strategic timing in representation matters affecting California’s public safety workforce.

Third District Court of Appeal Upholds Arbitrator’s Authority to Offset Discipline Sustained by the State Personnel Board in Retaliation Grievance

In a decision of considerable practical significance for California public employee unions and their members, the Court of Appeal for the Third Appellate District has reversed a trial court judgment that had limited an arbitrator’s remedial powers under a memorandum of understanding. The published opinion in Department of Human Resources v. California Correctional Peace Officers Association (2026 WL 1361422, filed May 15, 2026) clarifies that an arbitrator authorized to exercise the remedial authority of a Public Employment Relations Board ("PERB") administrative law judge may order rescission of a suspension previously upheld by the State Personnel Board, together with make-whole relief, where the award rests on a finding of retaliation for protected union activity rather than an attempt to supplant the SPB’s review on the merits. The ruling therefore preserves the vitality of concurrent or sequential grievance arbitration as a meaningful avenue for vindicating rights under the Ralph C. Dills Act even after the SPB has sustained discipline for cause.

Factual Background and Procedural History

Tracylyn Lopez, a correctional officer and CCPOA job steward at Salinas Valley State Prison, received a notice of adverse action for using profanity toward two fellow officers. After that matter was settled with a letter of reprimand, Lopez posted excerpts of the disciplinary materials on a union bulletin board visible to inmate workers, highlighting the surnames of the officers who had reported her. CDCR imposed a 60-workday suspension, which the SPB ultimately upheld on the ground that the posting promoted a “code of silence” and constituted inexcusable neglect of duty and failure of good behavior under Government Code section 19572, subdivisions (d) and (t).

Separately, Lopez filed a contractual grievance alleging that the suspension violated section 5.03 of the applicable MOU, which incorporates the Dills Act’s prohibitions on retaliation for protected union activity. CCPOA pursued the grievance to arbitration. The arbitrator found that CDCR had retaliated against Lopez for engaging in protected speech and representational activity, that the posting itself was not so opprobrious as to lose protection, and that CDCR failed to prove it would have imposed the same penalty absent the protected conduct. The arbitrator therefore ordered CDCR to rescind the notice of adverse action for the posting and to make Lopez whole through backpay and restoration of benefits and rights.

CDCR petitioned the superior court to vacate or correct the award, arguing that the arbitrator had exceeded her powers by interfering with the SPB’s constitutional authority to review disciplinary actions and by undermining public policy against the code of silence. The trial court denied the petition to vacate but granted the petition to correct, striking the provisions directing rescission and make-whole relief. CCPOA appealed.

The Court of Appeal’s Analysis

The Third District began from the well-established principle that judicial review of labor arbitration awards is extremely narrow, particularly in the public employment sector where strong policies favor collective bargaining and the finality of arbitral awards. An arbitrator exceeds her powers only in limited circumstances, including where the award violates an unwaivable statutory right or contravenes an explicit legislative expression of public policy. The public policy exception itself demands a two-part inquiry: identification of an explicit, clear, or well-defined and dominant expression of policy, followed by a determination that the award itself, not merely the underlying conduct, conflicts with that policy.

Applying this framework, the court concluded that the SPB’s constitutional authority under article VII, section 3, subdivision (a) to “review disciplinary actions” constitutes an explicit expression of public policy. Yet the arbitrator’s award did not contravene that policy. The SPB had reviewed the suspension for cause under the Civil Service Act and the merit principle; the arbitrator had examined whether the same discipline constituted retaliation for activity protected by the Dills Act and the MOU. These inquiries, while overlapping factually, are legally distinct. The SPB did not address the Dills Act claim, and the arbitrator did not purport to review or reverse the SPB’s determination on the merits. Instead, the award offset the suspension by providing a contractual remedy for the separate violation. Because enforcing one determination did not require violating the other, no inherent conflict arose.

The court similarly rejected the argument that the award undermined legislative and agency policies aimed at combatting the code of silence. While that policy is undoubtedly important, it does not mandate any particular length of suspension or preclude an arbitrator from finding that discipline was imposed for retaliatory reasons and ordering appropriate contractual relief. The award itself therefore did not conflict with an explicit expression of public policy.

Implications for PERB Retaliation Charges and Disciplinary Appeals Involving Overlapping Circumstances

This precedent confirms that civil service discipline and public sector retaliation claims (including those filed before PERB) proceed on separate but compatible tracks. An adminsitrative appeal ruling upholding discipline for cause does not, standing alone, preclude a finding from PERB (or an arbitrator in a grievance) that the same discipline violated a public sector labor statue (such as the MMBA or the Dills Act) or an MOU. PERB or the arbitrator can also order rescission and make-whole relief, notwithstanding the outcome of the disciplinary appeal. The appellate court noted that an award that offsets rather than purports to reverse or veto the SPB decision survives review and avoids the concerns raised in earlier authority such as State Personnel Bd. v. Department of Personnel Admin. (2005) 37 Cal.4th 512. Public sector unions may therefore pursue grievances and PERB unfair practices charges in appropriate cases without a favorable award automatically being judicially nullified on public policy grounds.

The decision also underscores the importance of preserving evidence of retaliatory motive and protected activity throughout the disciplinary process. Where emails, timing, or disparate treatment suggest anti-union animus, a well-developed record can support an offsetting remedy even after the disciplinary action has been upheld in the administrative appeal.  

Considerations for POST Decertification Proceedings Under Senate Bill 2

It is important to distinguish the framework addressed in this case from the decertification process established by Senate Bill 2. Under that statutory scheme, the Commission on Peace Officer Standards and Training, through its Peace Officer Standards Accountability Division, conducts an independent investigation into allegations of serious misconduct as defined in Penal Code section 13510.8. The Commission applies a clear and convincing evidence standard, higher than the preponderance standard that typically governs most disciplinary appeal proceedings, and its review of the entire record is not automatically constrained by prior agency or arbitral findings.

A sustained finding against an officer in a disciplinary appeal or arbitration does not, by itself, relieve POST of its obligation to satisfy this heightened evidentiary threshold. POST remains required to prove its case independently under the clear and convincing standard, even where the SPB, a local civil service commission or an arbitrator has already found misconduct.

It bears repeating that the appellate case involved distinct legal questions: whether discipline was supported by cause under the Civil Service Act, on the one hand, and whether that same discipline constituted unlawful retaliation for protected activity under the Dills Act and the MOU, on the other. By contrast, a POST decertification proceeding under Senate Bill 2 will ordinarily address substantially the same legal question presented in the underlying disciplinary appeal, namely, whether the officer engaged in the alleged serious misconduct, albeit under the heightened clear and convincing evidence standard rather than the preponderance standard typically applied in disciplinary appeals. This distinction between overlapping versus distinct legal inquiries helps explain why the Court of Appeal found no public policy conflict in the arbitration award, while also illuminating why a favorable determination in a disciplinary proceeding may carry greater preclusive potential in a subsequent decertification matter.

By contrast, a favorable factual or legal determination rendered in favor of the officer in the disciplinary appeal on the same serious misconduct allegations could in appropriate circumstances give rise to collateral estoppel or res judicata. Where the traditional elements are satisfied, including identity of issues and sufficient privity between the employing agency and the Commission, such a finding may preclude POST from relitigating those matters in a subsequent decertification proceeding. 

Conclusion

In light of this authority, an unsuccessful disciplinary appeal before the State Personnel Board does not preclude parallel unfair practice litigation. PERB would likely not be precluded from reviewing an upheld disciplinary action for unlawful retaliation under the MMBA, Dills Act, or other labor statute, nor would it be restricted in fashioning appropriate remedies for such violations. The Third District’s opinion represents a meaningful affirmation that carefully framed awards addressing retaliation will withstand judicial scrutiny.  

Arizona Federal Court Bolsters First Amendment Protections for Off-Duty Peace Officers in Protest Retaliation Matter

In a decision issued on May 21, 2026, the United States District Court for the District of Arizona addressed significant questions regarding the First Amendment rights of off-duty peace officers who engage in political expression and counter-protest activities. Although the court denied the plaintiffs’ request for a preliminary injunction that would have ordered the reinstatement of Sergeant Dusten Mullen to paid administrative leave, it delivered a detailed and favorable analysis of the merits of his First Amendment retaliation claim. 

Sergeant Mullen, a Phoenix Police Department supervisor, went to Hamilton High School on January 30, 2026, to check on his son and remained to counter-protest an anti-ICE student demonstration. He was off duty, out of uniform, and did not identify himself as a law enforcement officer. He wore a face covering together with a T-shirt that read “Trump 2024,” which the court recognized as symbolic speech addressing the salient political issue of immigration enforcement. Sergeant Mullen also recorded his interactions with the student protestors and with responding officers, an activity the court held was protected under the well-established First Amendment right to film matters of public interest in public places. Student protestors surrounded him, shouted curses, and threw water on him. He reported the incident to a Chandler police officer and out of frustration commented about allowing students to assault him.

The video evidence and sequence of events later established that Sergeant Mullen’s remark to the Chandler officer reflected frustration with the limited police response rather than any encouragement of assault. The Phoenix Police Department’s Professional Standards Bureau initially classified the matter as a Class II violation that would not result in termination. After media reports surfaced in April 2026 and Phoenix City Councilwoman publicly criticized his off-duty conduct and questioned his continued employment, the investigation abruptly changed course. The lead investigator was directed to elevate the violation to Class III, to sustain an additional allegation without new factual findings, and to complete the report on an accelerated schedule despite repeated requests for more time. A pre-dsiciplinary hearing was held on May 11, 2026, and termination followed three days later. The court found this timeline, together with the investigator’s testimony describing unprecedented pressure and departures from normal procedure, sufficient to support the inference that Sergeant Mullen’s protected activity was a substantial or motivating factor in the adverse employment action.

The court held that Sergeant Mullen engaged in protected First Amendment activity as a private citizen on matters of public concern. It stressed that speech addressing police competency and core political questions such as immigration enforcement occupies the highest rung of First Amendment values. Defendants failed to carry their burden of demonstrating either an adequate justification for treating Sergeant Mullen differently from other members of the public or that they would have reached the same termination decision absent the protected conduct. Their predicted disruption rested on speculation and negative publicity rather than evidence of actual or imminent workplace interference. The court emphasized that core First Amendment speech by an off-duty employee requires a particularly vigorous showing of disruption. The video did not evidence any intent to provoke a crime and the administrative investigation did not support termination prior to the media publicity. The court therefore concluded that the plaintiff demonstrated a strong likelihood of success on the merits of the First Amendment retaliation claim.

Nevertheless, the court found that Sergeant Mullen had not established irreparable injury sufficient to grant a preliminary injunction. Rather, the court hled that monetary damages or back pay awarded in the ordinary course of litigation can compensate any loss of income. The court noted that the public announcement of his termination had already occurred and  the requested relief would not thaw the chilling effect on other officers. It therefore denied the motion for a temporary restraining order and preliminary injunction.

Although the court denied injunctive relief, the court’s favorable treatment of the underlying First Amendment retaliation claim bolsteres the protections afforded public employees. This case confirms that generalized or speculative predictions of disruption will not suffice, particularly where the speech addresses matters of core political concern and occurs off duty. The ruling further cautions agencies against allowing external political pressure or media attention to drive investigative findings without independent evidentiary support. 

The decision reinforces the importance of distinguishing between legitimate operational concerns and content-based objections to an officer’s political views. It further underscores that policies governing off-duty conduct and social media must be narrowly tailored and applied consistently, lest they become vehicles for viewpoint discrimination.  The underlying litigation remains ongoing with an appeal pending of the denial of preliminary injunctive relief.
