The 2023 Kaiser Permanente Strike And The Deal That Followed

In October 2023, roughly 75,000 Kaiser Permanente nurses, pharmacists, and technicians walked off the job in the largest healthcare strike in U.S. history. Three days later they had a landmark contract. The episode is a clear case study in what organized healthcare workers can win at the bargaining table, so here is what happened and what the deal delivered.

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 in Oakland. Coalition members ratified it later that month.

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. 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. 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.
