I changed jobs a few months because of a supervisor who was a bully. When I look back at the situation, one thing that sticks out is that the supervisors above her-- all but two were men-- would never tell her to watch her behavior and how she treats staff, and to stop the gossiping. A few of us staffers went to an upper manager and complained about her. He just told all of us that he likes to let his team leaders run their own unit as they see fit. Well, from what I know, they now have a lawsuit filed against them because of her. Also, three great staffers left. Why does this happen? How could top leadership just allow someone to behave this way? I can't imagine it's only because she's friends with someone high up, or her uncle is some politician or bigwig at a Fortune 500. I've seen this happen at a few workplaces over the years.
