To all staff reporting such events. Please ensure you fil in an incident/accident report form at your establishment. Keep a copy for yourself. This can be used at a future date when you suffer stress or injuries for the assault. No evidence ,no claim that you suffered a work place accident. If you are treated by a doctor again obtain evidence of your visit. Clearly it is important report this to the police. Too often nothing happens to these students. They graduate to attacking old people , ambulance staff and fire persons. A few go on to murder people in the community just like in my LA. Failure to speak to you for a week means the SMT have failed in their duty of care. Perhaps they were too busy doing book checks and walking about with a clip board !!!! Union ask for refusal to teach. These pupils are a danger to other pupils in your school.
