First off I'm a supervisor in a nursing home ane noone should be screaming at you including nurses. It's harder than you think to get rid of bad employees. People start to give up and not write them up. What I tell my staff is continue to write them up because we do track it and as soon as we can legally fire them we will and we do. If you like your job and don't want to leave talk to your boss and don't let the nasty's get you down!
