I think I know this lady! People like this should work alone. Great on standing up and getting a different position and saving your sanity at the same time. You can’t win those types. I call them professional button pushers.
I was bullied very badly at a new job, and when I complained I was told “she’s been here over 15 years” and “she always does (insert whatever was happening) to new people”.
I was there about a month before I really couldn’t take it any more and got my coat and left without saying a word.
