Today as I was dismissing my class, a few students (from another class) were stood outside my room tugging on the door. They were causing a commotion as they were waiting for their friends. I asked them to move along the corridor, but they did not. A few minutes later, I started to dismiss my class, row by row. Suddenly I am hit in the side of my head by a metal object. I asked who did it, the boys at the door denied involvement. I was very calm. I dismissed the rest of my class and then I picked up the 'thing'... a solid metal door stop in the shape of a sphere which is screwed in the ground, with the screw still intact. I locked my door and went straight to my department office, I was shaking and crying. I told my head of department and a senior member of staff. They looked at CCTV (which we have in the corridors) they saw who threw the door stop. I'm not sure what will happen to him, perhaps a detention knowing my school. What should I do now? My head genuinely hurts as I was hit on my left temple. Considering going to A&E. What should happen to the student? Whether he meant to hurt me or not is irrelevant right? I'm so upset right now, I love teaching but I think today might have been my last as a teacher.
