Been a bad couple of weeks so far but this week had an incident I took as serious. Student removed from my lesson for refusing to put down chemicals in a prac and laughing at me when I attempted to get him to do so. In returned to collect his report at the end, on report as he had JUST come back from exclusion, I handed him his report as the class were standing behind chairs ready for dismissal and told Him to go. He then stood in front of my door, foot against it hand on handle and said nah I’m not gonna go, laughing hysterically. He refused to go. Refused to let the class go. I took this as a serious issue for safety and also intimidating behavior. I emailed head of house who said why are you telling me it’s a department issue. Bearing in mind he is on behavioural report with her and on the report there is no space to write this. I’ve had no one ask anything more about it. Nor punish him. I spoke to union who said a incident form should be filled in. Am I overreacting?!
