SAN FRANCISCO (AP) — Kaiser Permanente nurses in California have approved a new contract that boosts pay and improves patient care along with health and safety protections for nurses, a union official said. The contract also includes paid time for 25 registered nurses annually to participate in the union's disaster-relief program, which has dispatched hundreds of nurses to help with medical services following disasters from Hurricane Katrina to the Haiti earthquake to Typhoon Haiyan in the Philippines. About 2,600 psychologists, counselors and therapists held a two-day strike earlier this month to bring attention to what they say are inadequate staffing and long wait times for appointments.
