An escalating labor dispute at Kaiser Permanente has resulted in one of the largest healthcare strikes in recent California history, with approximately 31,000 registered nurses and healthcare workers walking off the job. The strike, which began on January 26, 2025, involves members of United Nurses Associations of California/Union of Health Care Professionals (UNAC/UHCP) across multiple Kaiser facilities throughout California and Hawaii.
Strike Expansion Includes Pharmacy and Laboratory Workers
The labor action intensified significantly on Monday, February 9, when more than 3,000 additional pharmacy and laboratory workers joined the strike. United Food and Commercial Workers (UFCW) Southern California locals, representing Kaiser Permanente pharmacy and laboratory employees, delivered a 10-day Unfair Labor Practice (ULP) strike notice to Kaiser Permanente executives. The ULP strike commenced on February 9 at Kaiser facilities throughout Los Angeles, Orange, San Diego, San Bernardino, Riverside, Ventura, and Kern counties.
Union Allegations and Bargaining Stalemate
According to UNAC/UHCP’s official statement, the strike protests what unions characterize as Kaiser’s labor violations throughout contract negotiations. Union representatives assert these violations have compromised patient care quality and prevented frontline healthcare workers from securing fair contract terms. The unions claim that national bargaining has remained stalled for over a month after Kaiser management reportedly walked away from negotiations in December 2024.
Unfair Labor Practice Charges Filed
In response to the bargaining impasse, UNAC/UHCP, UFCW Local 770, and other unions affiliated with the Alliance of Health Care Unions filed Unfair Labor Practice charges with the National Labor Relations Board (NLRB). The charges allege that Kaiser “unlawfully refused to bargain in an attempt to bypass the agreed-upon national bargaining process and interfere with good-faith negotiations that had been ongoing since April 2025.”
Kaiser Permanente’s Response to Strike Action
Kaiser Permanente has issued comprehensive statements characterizing the strike as “unnecessary, disruptive for our members and patients, and counterproductive to reaching a contract agreement.” The healthcare organization reports that employee participation in the strike has been declining, with more than 35% of striking employees returning to work across affected locations. Some facilities have seen return rates as high as 55%.
The organization maintains that returning employees are joining physicians, nurses, staff, managers, and contingency workers to continue delivering patient care throughout the strike period. Kaiser has been actively rescheduling non-urgent procedures that were postponed during the initial strike week.
Allegations of Union Intimidation
Kaiser Permanente has raised concerns about what it characterizes as union intimidation tactics. The organization reports hearing from employees who are “afraid to return to work as they are being threatened by their union with fines for coming back in to care for patients.” Kaiser maintains that employees who wish to return to patient care should not face intimidation from their unions and has committed to protecting employees from harassment and retaliation.
Financial Sustainability Concerns
Kaiser Permanente contends that the unions’ wage demands are economically unsustainable. The organization argues that meeting these demands would make healthcare less affordable for Kaiser Permanente members and customers, with broad-reaching implications for healthcare costs across every market they serve. Kaiser states it has worked for more than eight months to reach national and local agreements that support employees, partnership relationships, and care affordability.
Operational Continuity During Strike
Despite the significant workforce disruption, Kaiser Permanente maintains that its facilities remain “fully operational” through the deployment of temporary contract professionals and management staff. The organization has expressed disappointment that union leaders chose to strike despite the potential impact on patient access and experience, while reaffirming its commitment to ensuring members continue receiving high-quality, compassionate care.
The ongoing strike represents a critical juncture in healthcare labor relations, highlighting tensions between worker advocacy, healthcare affordability, and patient care continuity in California’s complex healthcare landscape.
