Some 75,000 Kaiser Permanente workers are taking to picket lines in multiple states over wages and staff shortages. Unions representing the workers who walked off the job Wednesday approved a strike for three days in California, Colorado, Oregon, Washington, and one day in Virginia and the District of Columbia. Doctors are not participating, and the company says it will keep its 39 hospitals open. Kaiser union members say understaffing is boosting the hospital system’s profits but hurting patients, while Kaiser say they offer better compensation than competitors. There have been work stoppages within multiple industries this year in the U.S.
