I work in large secondary school and on three occasions this term, I've had water bombs thrown into my teaching room, soaking displays and important documents. On each occasion, the students have scarpered before I've been able to identify them. After the second incident, which occurred at lunch, I reported the situation to management. However, it was decided that it was the responsibility of lunch time supervising staff to make sure students did not have the opportunity to be in the vicinity of my room, which incidentally is next to the student toilets. On the third occasion, I was really upset. think it was more the realisation that this was my life and there was nothing I could do about it, short of trying to find another job elsewhere. It happened on the changeover between lessons in the morning, so there was no lunchtime supervising staff around, and the other teachers on my corridor were already in their rooms and teaching. Obviously, the perpetrators were the stragglers arriving late to lessons, if at all. Last week, at the close of day on Friday, I decided to lock my door. The atmosphere in the corridors felt a bit crazy. I think most of SLT were out on a course. About two minutes later, I became aware of someone shoving themselves up against the door, pushing the door handle down and finding it locked. 'Oh my God, she's gone and locked the door on us!' cried one boy, and before I could get to the door to try and see who it was, there was the sound of footsteps as they all scattered. I know SLT investigated the third incident, but I don't think they ever found out who was behind it. Meanwhile, I have been asking for a security camera to be placed in a discreet location in that part of the corridor, as it it quite remote and students have ready access to stairs and the exit door should they wish. To date, however, I have been told that no camera is going to be installed. There is already one on the stairwell and in the loos, although neither have picked up on anything unusual. What should I do? It's reached the stage where I no longer feel safe in my own teaching room, and it's really getting me down.
