I am CoG at a primary school, where we have a recently appointed interim HT. I have this week received two phone calls from staff saying that the HT has been bullying them since her arrival. One teacher has spoken to me on behalf of other members of staff, as they thought it would be better than me receiving several phone calls from them individually. This bullying behaviour has also been mentioned to me by the school secretary, who has already started to look for another job. The staff have asked me not to discuss with anyone, as they do not feel that they want to make a formal complaint at this point. It's taken a lot of courage for these teachers to phone me directly, and I have respected their request to keep this confidential. I have suggested they keep a log of incidents, and take some advice from their union. As I understand it, my hands are tied unless they make a formal complaint. I am concerned about the HTs behaviour, as she has started to display an aggressive attitude to me aswell when I challenge her - which is my role. She seems to take this personally and react as if I have questioned her ability to do the job. There is no question that she is an effective HT when it comes to raising standards, but now I am wondering what the price of this will be? The GB need to consider extending the HT contract in the next couple of weeks. If we extend, I know that staff will look for other jobs, but officially we have no reason not to extend. Have I done the right thing so far - and is there anything else I need to do, or can do without acting inappropriately? I have read a lot of posts on here where it's assumed the CoG would never support a teacher rather than the HT but I like to think that I don't fall into that camp and would treat any complaints seriously and objectively.
