The strike
The Coalition of Kaiser Permanente Unions represents about 85,000 workers across 11 unions in California, Oregon, Washington, Colorado, Virginia, and Washington, D.C. It called the strike over low wages, short staffing, and disputes on healthcare and pension benefits. The walkout ran from October 4 to October 6.
Acting U.S. Labor Secretary Julie Su stepped in to mediate, and within a week the two sides reached a tentative agreement. Coalition members ratified it later that month by a 98.5% vote (Coalition of Kaiser Permanente Unions).
What the deal won
The headline was a 21% across-the-board raise over four years: 6% in October 2023, then 5% in each of the next three years (NPR). Kaiser's pre-strike offer had topped out around 12.5% to 16%.
The contract also set new minimum wages phased in over three years, reaching $25 an hour in California and $23 an hour in other Kaiser states. Workers received a $1,500 ratification bonus. The agreement added a redesigned Performance Sharing Plan with a guaranteed minimum payout, renewed protections against outsourcing and subcontracting, improved medical and retirement benefits, and new tracking of staffing vacancies.
The strike was not Kaiser's only labor pressure point. The system also reached a $200 million settlement with California over long delays and inadequate referrals in its mental health care, which included a $50 million fine and a commitment to invest $150 million over five years (CalMatters). Together, the strike and settlement landed at a moment of rising union activity across U.S. industries, and the contract set a benchmark other health systems now get measured against.
