(Portland, OR) -- Kaiser Permanente is postponing some non-urgent surgeries in the midst of a three-day strike by 75-thousand workers. The healthcare company said it blocked out time in the coming weeks to get this week's patients rescheduled as quickly as possible. The unions representing the workers say understaffing at the hospitals is boosting profits but hurting patients, and causing employee burnout. Yesterday, Kaiser said it's reached several "tentative agreements" on wages, hiring, and benefits. But the coalition of unions running the strike nationwide says they are still waiting for a more meaningful approach to key priorities.
