The most violent job in Washington state isn't being a police officer or a security guard. It's working as a nurse's aide. Seattle public radio station KUOW-FM made that finding as part of an investigative series on workplace safety airing this week. The station found that violence strikes healthcare workers in Washington at six times the state average, and frontline caregivers in emergency rooms and psychiatric wards get assaulted even more than that. The single most violent workplace in the state is at Western State Hospital, where criminal defendants are taken when they are found incompetent to stand trial. Workers at psychiatric hospitals are assaulted on the job more often than anybody else -- 60 times more than the average worker in Washington State.
