Inside Kaiser’s Playbook: How Management Responds to Record-Breaking Strikes
At its peak, approximately 34,000 healthcare workers were on strike at Kaiser Permanente facilities across California and Hawaii in what was the largest healthcare strike in U.S. history. By examining how one of America’s largest nonprofit health systems is managing this crisis, we can see the full playbook major healthcare employers use when facing long strikes.
How the Strike Escalated to Historic Proportions
On January 26, approximately 31,000 nurses and health professionals launched an open-ended strike across Kaiser’s California and Hawaii facilities. These workers—registered nurses, pharmacists, physician assistants, physical therapists, and mental health professionals—represented the United Nurses Associations of California/Union of Health Care Professionals (UNAC/UHCP).
Their demands centered on three issues: wage increases that keep pace with California’s cost of living, improved staffing levels to address chronic understaffing, and a return to good-faith national bargaining. Kaiser had abruptly suspended national negotiations in late 2025, prompting unions to file complaints with the federal labor board saying Kaiser broke labor laws.
On February 9—two weeks into the nurses’ strike—more than 3,000 pharmacy and laboratory workers joined the picket lines. These workers, represented by the United Food and Commercial Workers (UFCW) Locals 135 and 770, had deliberately waited to strike.
By adding pharmacy technicians, pharmacy assistants, and clinical laboratory professionals in a second wave, the unions created successive pressure points rather than a single manageable disruption. Pharmacy workers control prescription fulfillment. Lab workers handle diagnostic testing and blood work analysis. Without them, Kaiser couldn’t simply maintain operations by shuffling existing staff—the system would face serious backups in services.
This phased approach served multiple purposes. It allowed unions to assess Kaiser’s initial contingency response. It prevented Kaiser from simultaneously preparing for both groups striking. And it created escalating operational constraints that would compound over time rather than hitting all at once.
Kaiser’s Multi-Layered Response Strategy
When the strike began, executives revealed they’d developed extensive contingency plans to maintain operations. The response operated on four simultaneous tracks: keeping things running, legal strategy, money arguments, and public messaging.
Maintaining Operations Through Replacement and Reassignment
Kaiser’s operational strategy focused on the most urgent services first. Emergency departments and acute inpatient care would continue at normal capacity. Urgent care would remain open. Outpatient clinics would shift to virtual care where possible. Non-urgent laboratory services and non-emergency prescriptions would experience delays.
The health system deployed three mechanisms to maintain staffing. First, Kaiser reassigned existing employees to strike locations, with management stating that “many of our employees have volunteered to be reassigned.” Second, management-level clinicians—including pharmacy directors and senior nurses—directly provided patient care. Third, Kaiser brought in replacement workers.
Kaiser began “hiring and training nurses, clinicians, and other staff to work during the strike, the majority of whom have worked at Kaiser Permanente before.” By recruiting former Kaiser employees and experienced workers from other systems, management could claim these weren’t inexperienced temps but qualified professionals who knew Kaiser’s protocols.
By the strike’s third week, Kaiser claimed that “over 35%” of striking employees had returned to work. Union sources disputed this figure, suggesting Kaiser was counting workers who’d never participated in the strike or were temporarily absent. The conflicting data became its own battleground—each side used different counting methods to support competing narratives about strike solidarity and operational capacity.
Legal Maneuvering Over Strike Classification
Kaiser pursued a parallel legal strategy that could completely change how the strike ends. The health system’s lawyers worked to change the legal category of the strike from an “unfair labor practice strike” to an “economic strike”—a distinction that makes a huge difference under federal labor law.
If this is an unfair labor practice strike, workers have the legal right to reinstatement even if Kaiser hires permanent replacements. If it’s an economic strike, Kaiser can permanently replace striking workers who’d then lose their jobs.
The unions had filed unfair labor practice charges in December 2025, alleging Kaiser suspended national bargaining without cause, denied workers access to union representatives, failed to provide information necessary for bargaining, and surveilled union activity. Kaiser responded through its legal team at Greenberg Traurig, filing counter-charges and building a case that the strike was fundamentally about economics—wages and benefits—rather than employer violations.
Kaiser also moved to restructure the bargaining process itself. The health system filed a court petition seeking confirmation that it could shift remaining issues from national to local bargaining tables. This would break up the union’s power by forcing each local to negotiate separately rather than negotiating together at the national level.
The Financial Messaging Battle
Kaiser faced a credibility problem: the health system holds approximately $66 billion in cash reserves. Unions prominently featured this figure as evidence that Kaiser could easily afford wage increases without harming patient care or raising costs.
The union document “Profits Over Patients” presented detailed financial analysis showing Kaiser reported approximately $7.9 billion in net income in the first three quarters of 2025 alone. Kaiser’s own 2025 financial statements confirmed total income of $127.7 billion and net income of $9.3 billion for the full year.
Kaiser’s financial response reframed building up reserves as necessary rather than excessive. Chief Financial Officer Kathryn Lancaster argued that “our how many days we could operate on our cash reserves is still below the industry average for organizations with similar financial strength.” The reserves, Kaiser claimed, supported capital programs including “earthquake-safe hospital buildings, facility improvements, and new technology”—not excess profits available for distribution.
Kaiser also emphasized its wage offer as historically generous: “a 21.5% wage increase over the life of the contract, with 16% within the first 2 years. When automatic raises and local pay bumps are included, the total average increase is approximately 30%.” The system highlighted that “unionized Kaiser workers already earn, on average, about 16% more than similar roles at other organizations.”
But unions countered that Kaiser’s math was misleading. UNAC/UHCP leadership issued statements titled “Fuzzy Math,” arguing Kaiser was “inflating the numbers in our proposals by rolling together step progressions, longevity adjustments, and compensation nurses already earn over time. That’s not a raise, that’s accounting gymnastics.”
Public Relations Across Multiple Audiences
Kaiser’s communications operated on different tracks for different audiences. To the general public and media, Kaiser emphasized operational continuity and patient safety. To patients, the system provided detailed information about service modifications—which pharmacies were closed, where to get lab work done, how to use mail-order prescriptions.
To the financial community, Kaiser provided updates on operational impacts and reserve adequacy. To employees, Kaiser communicated that continued strikes were “unnecessary when such a generous offer is on the table” and that striking workers “have lost 4 months of the wage increases represented in our offer.”
Kaiser’s messaging positioned the system as protecting patient interests while characterizing unions as prioritizing worker demands over patient welfare. This framing carries particular weight in healthcare, where patient safety concerns can override worker advocacy in public perception.
Kaiser also criticized the union’s approach as violating the Labor Management Partnership Agreement that had governed Kaiser-union relations since 1997. By suggesting that strike action itself represented bad faith under the partnership framework, Kaiser attempted to invert responsibility—said the unions were the ones violating established agreements rather than management’s alleged refusal to bargain.
Who’s Coordinating This Strike
The strike represents coordination between two major labor organizations. UNAC/UHCP, founded in 1972, represents approximately 40,000 registered nurses and health professionals in California and Hawaii. The organization is affiliated with AFSCME and the National Union of Hospital and Health Care Employees, giving it connections to broader labor networks.
The UFCW represents pharmacy technicians, pharmacy assistants, clinical laboratory scientists, and medical technologists. With over 1.3 million members in retail, food processing, and healthcare, UFCW brings experience from decades of labor relations.
Both unions participate in the Alliance of Health Care Unions, formed in 2018 as a coalition of 23 local unions representing Kaiser workers. The Alliance operates a national bargaining committee structure, allowing local unions to maintain autonomy while negotiating national contracts covering wages, benefits, and work standards in all Kaiser regions.
The decision to escalate from nurses to include pharmacy and laboratory workers was carefully planned. UFCW had authorized its members to strike in December 2025 but held back from the initial January action. This phased approach prevented Kaiser from simultaneously preparing for both groups and created successive waves of disruption.
Not all Kaiser workers are striking. The Coalition of Kaiser Permanente Unions represents approximately 85,000 workers, but the striking portion includes about 34,000—some have contracts that don’t permit striking, others chose not to participate.
What History Teaches About Healthcare Strikes
This isn’t Kaiser’s first major labor action. In October 2023, approximately 75,000 Kaiser workers conducted a three-day strike protesting understaffing and unfair labor practices. That strike, then the largest in U.S. history, resulted in a settlement reached with intervention from Acting U.S. Labor Secretary Julie Su.
The 2023 strike won substantial concessions, including significant wage increases and commitments to working together to figure out staffing levels. It established that coordinated large-scale Kaiser strikes could generate results.
The 2026 strike appears designed to build on that precedent while escalating intensity through targeting of pharmacy and laboratory workers. The decision to add these workers in the second week rather than simultaneously suggests union learning about when to add more workers to the strike.
The broader precedent from non-healthcare labor offers context. The 1997 UPS strike demonstrated the power of targeting the parts of operations that would hurt most—shipping and logistics functions needed for company operations. The unions’ strategic selection of pharmacy and laboratory workers reflects similar understanding of operational vulnerability.
But healthcare differs substantially from manufacturing or logistics. Healthcare faces unique constraints because patient safety and continuity of care impose limits on how much they can disrupt things without hurting patients.
A major study found that strikes involving workers don’t generally increase mortality rates, contradicting common assumptions. However, strikes can delay non-urgent care, potentially causing harm to patients with time-sensitive conditions.
Strategic Options for Amplifying Pressure
Coalition Expansion to Other Healthcare Systems
The UAW’s 2023 strategic targeting of Ford, GM, and Stellantis one at a time rather than simultaneously maximized industry disruption. The unions could publicize Kaiser’s wage offers and financial position to competing systems in California—Sutter Health, Dignity Health, UC Health—potentially triggering organizing campaigns at multiple systems.
This could transform the Kaiser strike from company-specific action into the opening move of broader changes to how the entire industry works. Systems operate in competitive markets where employees at rival organizations could be motivated by evidence that Kaiser employees are winning superior terms.
The challenge: competing systems have different financial positions and ownership structures. UC Health’s public status creates different negotiating dynamics than Kaiser’s nonprofit model. Organizing campaigns require substantial resources and time.
Getting Patients to Tell Their Stories
The unions could organize patients to share their experiences about delayed care, coordinate media interviews featuring patient safety advocates, and seek endorsements from prominent professionals legitimizing union claims about understaffing’s impact on care quality.
This could change the story from “unions vs. management” to “understaffing harms patients.” Kaiser’s operational continuity narrative is vulnerable to counter-narratives about care quality degradation. Patient voices carry different credibility than union advocacy.
The challenge: securing patient participation requires overcoming privacy concerns and patient loyalty to Kaiser. Identifying health professionals willing to publicly criticize Kaiser requires overcoming professional norms against public criticism of competitors.
Pressuring Kaiser Through Investors
The unions could partner with investment funds focused on social responsibility and pension funds with union trustee representation to communicate directly with Kaiser’s board about labor relations concerns. This could create pressure through financial markets rather than purely through labor action.
Kaiser is a nonprofit, but its financial markets—including bond financing and investment returns—operate within conventional capital markets where investor concerns about how the organization is run and its reputation matter. Institutional investor pressure has historically shifted corporate behavior on social and ethical issues.
The challenge: nonprofits face less shareholder pressure than publicly traded companies. Kaiser’s financial performance has remained strong despite the strike, reducing investor concerns. Building coalition among institutional investors requires months of advocacy work.
Organizing Replacement Worker Networks
The unions could reach out to staffing agencies ahead of time, travel nurse companies, and temporary worker networks to discourage contractor participation in Kaiser replacement efforts. This might involve workers talking to other workers about the strike’s issues, or community pressure on staffing agencies not to profit from strikebreaking.
Replacement workers are often themselves employees in unstable jobs who might support unions. Direct communication about strike issues and appeals to worker solidarity have historically influenced replacement worker decisions.
The challenge: replacement workers often work for distant firms with no location-based community pressure. Individual workers’ economic desperation often overrides solidarity appeals. Legal constraints limit union communication with non-represented workers.
Public Accountability Campaigns Targeting Leadership
The unions could widely share information about Kaiser CEO Gregory Adams’ 2023 pay of $12.7 million and other executive compensation totaling $93 million as evidence of available resources, alongside worker testimonials about financial struggles.
The gap between executive compensation and worker wages can be framed as contrary to healthcare mission values. In nonprofit healthcare, pointing out this contradiction is especially powerful.
The challenge: nonprofit leaders often have stronger protection from campaigns targeting them personally than for-profit executives. Individual targeting can provoke backlash if perceived as unfairly personal rather than institutional.
Pushing Hard on Unfair Labor Practice Complaints
The unions could combine the current December 2025 unfair labor practice charges with additional filings documenting any new violations during the strike—surveillance of union activity, differential treatment of replacement workers, discipline of strikers.
NLRB proceedings create ongoing legal requirements for employers and can result in solutions like paying workers for lost wages and requiring certain contract terms, and orders requiring Kaiser to negotiate that extend beyond what bargaining alone might achieve.
The challenge: NLRB proceedings are slow, often requiring 1-3 years for resolution. Legal victories don’t automatically translate into contract gains.
Reframing Demands as Patient-Protective
Rather than framing union demands as worker benefits alone, the unions could systematically communicate that rules about how many patients each nurse can handle, adequate lab staffing, and pharmacy resources directly enable better patient outcomes, reduced medical errors, and faster diagnoses.
This frames management as choosing lower quality care to maximize profits, not choosing affordability. Consumers and policymakers respond powerfully to patient safety framing. California’s legal safe staffing ratio requirements provide clear standards to judge whether management is right.
The challenge: Kaiser will counter-message that their quality measures prove adequate staffing. Distinguishing between legal minimum staffing and optimal staffing requires technical knowledge some audiences lack.
What Happens Next
If federal mediators speed up negotiations—potentially with Labor Department involvement similar to the 2023 strike—a settlement could emerge within weeks. This would require Kaiser to move substantially on wage percentages and staffing commitments, likely triggered by escalating economic or political pressure. Resolution would likely involve Kaiser increasing wage offers above the current 21.5-30% package, possibly moving toward mid-30s percent increases, along with concrete staffing language.
If neither side experiences sufficient pressure to move significantly, the strike could extend into March, April, and beyond. Extended strikes increase costs for both sides: workers lose cumulative wages while Kaiser faces ongoing problems running the hospitals and damage to its reputation. Precedent from the 1968 Memphis sanitation strike (65 days) and the 1989-1990 Pittston Coal Strike (10+ months) demonstrates that strikes can persist for extended periods.
Kaiser might offer concessions on certain issues—wages above current position—while holding firm on others like staffing language. This settling some issues now and others later would allow both sides to declare partial victory while leaving some issues for future negotiation.
The NLRB’s determination of whether this constitutes an unfair labor practice strike or an economic strike will substantially affect long-term outcomes. If the Board sides with unions, workers gain strong legal rights to get their jobs back even if Kaiser has hired permanent replacements. If the Board sides with Kaiser, the company’s replacement worker strategy becomes a more viable long-term alternative to settlement.
The strike’s resolution depends on four variables: how much financial pain from disrupted operations Kaiser can handle and reputation damage, union members’ willingness to keep striking despite losing paychecks, federal and state regulatory response to potential patient care impacts, and how this affects competition with other systems that might accelerate organizing elsewhere if Kaiser employees win substantial gains.
The strike occurs in the context of major labor activity nationally. The outcome will likely influence organizing efforts and bargaining positions at other major systems, making this strike important far beyond Kaiser itself.
The February 2026 Kaiser strike represents a test of worker power in twenty-first century healthcare. Unlike manufacturing strikes that historically defined American labor relations, this strike occurs within an industry where completely shutting down operations would be unethical, where patient safety concerns can override worker demands, and where management has enough money to keep going even with major disruptions.
Yet it also reveals the vulnerabilities of even massive, well-capitalized systems when faced with coordinated worker action targeting critical bottlenecks. Kaiser’s multi-layered response strategy reflects a smart approach to handling labor disputes in modern healthcare. The system’s ability to maintain acute care operations while accepting reduced outpatient services shows how large organizations can keep going and the limits of disruption workers can impose without embracing tactics that would directly endanger patients.
The unions’ strategic coordination—their timing of when to add more workers and targeting of pharmacy and laboratory workers—demonstrates unions getting smarter in designing strike action. The decision to phase in workers rather than striking simultaneously, the attention to maintaining solidarity across job classifications, and loudly publicizing Kaiser’s massive financial reserves as evidence of affordability all reflect lessons learned from previous strikes.
If the unions achieve substantial gains—significant wage increases above Kaiser’s current offer combined with concrete staffing commitments—the victory will likely accelerate organizing and bargaining intensity in American healthcare. Conversely, if Kaiser successfully sustains operations and maintains its current position, the system may establish a precedent demonstrating management’s ability to withstand even historically large strikes, possibly discouraging workers elsewhere from organizing.
The coordination between UNAC/UHCP’s 31,000 workers and UFCW’s 3,000 workers demonstrates that despite decades of unions being divided and competing with each other, labor retains the capacity for coordinated action on a historic scale. The strike’s duration, outcomes, and settlement will offer lessons about the balance of power in twenty-first century labor relations.
