First of all I am so sorry about what happened to you and the way that it was handled, it was and is unacceptable. Unfortunately I too have had a very similar experience both with a student and with my SLT. 3 Years ago I formally complained to both the police and the school about a student who was sexually inappropriate in his behaviour and the way he spoke to me both in and outside of school. He was suspended for a week, warned by the police and i refused to teach him. He was also a bright young man whose potential to do well shone through even his threatening side. However, a year later his threatening behaviour escalated and he began to follow me in the school, make sexual comments in my passing and even physically blocked me from leaving a room. I informed SLT formally...they assured me that they would handle it and that no police complaint was necessary. They took the approach of a 'man to man' chat because 'sometimes boys like girls.' I was feeling increasingly threatened by the student who remained in school without suspension and the feedback i recieved was that 'he had been spoken to.' Other staff began to come forward with their own complaints of his sexual inappropriacy and these were allegedly "handled" by the SLT. Unfortunately after 3 years of this boy being lightly slapped on the hand for his sexual misconduct, he began stalking me outside of school. The police are involved and the SLT have remained quiet on the issue. My advice would be to go to the police in the first instance! I believe that things have gotten as bad as they have because they were not dealt with the appropriate severity. I would also inform your Union. The action from SLT would be VERY different if these accusations were the other way around. As sad as it is I would advise you not to trust that your SLT has your best interest at heart. Do whatever it takes to make sure that you feel safe in your work place, your safety should be a top priority. If his behaviour continues and gets worse at least you will have it on police record. There is NO way that you should be going to work feeling sexually threatened by a student. Your response may give courage to other staff members or girls in the school to come forward with their stories too. This is too serious to keep quiet. Best of luck!
