Defintely call the police. Bodily injury is not ok, even if lots of folks think because it's a nurse that was attacked it doesn't count. There are laws out there that protect EMT's if they are attacked doing care, I believe it is a felony. I would think the facility who knowingly puts an employee in danger would be liabile for harm. Most facility's will not accept someone who is dangerous due to worker comp issue and liability. Defintely do not put yourself in harms way. Call for help!
