For coursework, students have to reply to an email the teacher has sent them. I received a malicious email. All school have done is put the student in 'remove' for the day. The email was sent off a year 10 student, the headteacher wont suspend the student because he is a child and is not sure the difference between right and wrong. He doesn't have any SEN but is misbehaving across the board. What do you think the next step should be?
