I was subjected to a tirade of bad language by a year 11 student in a class I was covering (I had asked him to do the work as he had his head on the desk). The language included lots of f*** o** and b*t**h as well as intimidating behaviour. He has SMT mentors who all sympathised as he often 'flips'. I don't think anything more than a telling off will result. What would happen in your school? Am I naive to expect stern consequences ?
