I'm an experienced Head of Dept, who moved to a new school 4 years ago. It is common knowledge that the team is very dysfunctional and have been for many years. As the newbie, despite being HOD,.I am treated very badly by them. They didn't like it when I prepared SOWs last year and just worked at their own pace. This year they've been asked to contribute, as a way if making them more involved and 1 has gone to complain to my line manager about it. This person sends me long emotive, factually incorrect emails that sound like she is building a case against me....even though SLT are clear there is no case to build. Anyone been in a similar position and have any advice?
