Most of Kaiser Permanente’s 2,600 mental health professionals, who are members of the National Union of Healthcare Workers, are expected to start a weeklong strike this morning, with 65 picket lines in West Los Angeles, Woodland Hills, and other locations throughout the state, the Daily News reports. The union alleges that Kaiser does not hire enough clinicians on its behavioral health staff to treat the growing number of patients, in violation of state mandates and industry standards.
