Sorry to hear you are dealing with this issue. I worked LTC years ago and had a similar experience, mine I believe was partially caused by the employer putting my bsn on name badge. It was pretty awful, and abusive. I went to nursing supervisor, and after one pretty nasty bashing all because I got there on time and the second nurse wanted my assignment and screamed and threatened until she got it, another nurse reported it, it was so bad, I reported it... nothing happened. In hindsight I wish I had told her she could have both sides and walked out and/or reported her to the board for unprofessional behavior. Hard core, but the abuse I endured was hard core as well. Someone told me later she was diverting and thats why she wanted the other side, it had blind corners. Today video is a powerful thing, I also wish I had used a phone video. But if you've talked to superiors and it hasn't helped, Leave. You don't deserve that, you don't have to tolerate it. You'rd worth more than that. Best of luck!
