I started on a maternity leave cover in January with said school. My hod has been nothing but cold and distant since I started. She is very unapproachable and has no people management skills. Whenever she talks to me she makes me feel like a tremouring nqt. I have behaviour problems with one of my year 9 classes. They are very low ability and mainly SEN with behavioural issues. She has now taken it upon herself to scrutinise every lesson I teach to this class, before, during and after the lesson. Part of me just wants to tell her to screw off but the the other part of me is making me act all humble and needy in front of her. She is making me feel physically sick when-ever I see her. Through speaking to other staff members it has very slowly evolved that they all have a problem with her. AIBU not to want to continue working in this environment?
