Thousands of healthcare workers at Kaiser Permanente are considering going on strike if no agreement is reached with their unions by the end of September. The workers are demanding improved working conditions and have concerns about understaffing and management proposals on wages and workforce development. The Coalition of Kaiser Permanente Unions, representing 40% of the workforce, will vote on authorizing a strike after their contract expires in October. The SEIU-UHW union has already voted to authorize a strike due to alleged violations of the law and concerns about patient safety. Kaiser Permanente is confident in reaching an agreement and disputes the union's claims, citing wage increases and active recruitment efforts. Negotiations are scheduled for next week.
