Nurses, medical technicians, and physical therapists ended a four day strike at Queen of Angels-Hollywood Presbyterian Medical Center as planned yesterday, with a rally outside the hospital and address workers? warning of more strikes to follow if management did not address workers? concerns in ongoing contract negotiations. Working since May 13 without a contract, members of Service Employees International Union Local 399 joined with community supporters at the rally to protest unsafe overstaffing and pay ranges lower than those at other nearby hospitals. Management was warned about the strike in advance by the union, and brought in replacement workers to maintain patient care---which, according to the union, deteriorated during the strike causing numerous complaints.
