I’m head of a department in a school, fairly new to the role as started last year. For the whole of the last year, my line manager has been unkind, cutting and “off” with me. She very snakey, lies about things and tries to create drama. I generally try to ignore it, challenge her on the bigger things and let as much go as I can. I go above and beyond to remain calm, be friendly and positive. Mostly because I don’t know how to handle it really. Today, a few members of my department told me that she’s been going down to their rooms and slating me openly. They say they don’t agree with her point of view and try to stay out of it, remaining quiet. Apparently this morning she was slating me in front of the whole team. I can’t really confront her - she will outright deny it as usual and lie. If I report her to someone else, I’ll have to drag the other members of staff onto it too. I’m so upset and just don’t want to go back to school at all. Any advice?
