A complaint has been filed on behalf of thousands of workers at University of California medical centers who allege they were threatened when they went on a two-day strike in May.
The complaint filed by the state Public Employment Relations Board outlined instances when UC administrators questioned workers about their participation in the walkout, told them their absence during the strike would be considered unauthorized and threatened disciplinary action.
A spokeswoman said UC administrators believe they acted in accordance with the law.
A union representing some 13,000 hospital pharmacists, nursing assistants, operating room scrubs and other health care workers held the strike at medical facilities in San Diego, Orange, Los Angeles, Santa Monica, San Francisco and Sacramento.
Nurses did not strike, but the walkout prompted the postponement of non-essential surgeries.
