I really need some advice. I am on my seventh year of teaching and never had this problem. I have recently moved year groups and I have a new TA who works between my class and my colleague's class. We are both having problems with her. There are 4 teachers and 2 TAs in the bay and it is as if she is the boss. She has a rude and aggressive manner. She will constantly find faults and disagree with whatever we suggest e.g. when talking about a display she said to my colleague, "I will do it because your handwriting is like a 5 year old's" and also "I will do display work this lesson because your lesson sounds boring." The problem is her mother is governor and other people seem to be frightened of her. We have been to our team leader but he appears also to be frightened of her and is her friend. Any suggestions?
