My HR manager called me in for an informal meeting to discuss my start back to term. This was because last year a physical assault by a pupil on another staff member in my room had triggered my pre-existing PTSD (that had been dormant for 14years). I had not taken any time off but had requested help with counseling through the school (which was denied as it would be too costly). I was expecting a supportive, informal meeting but this did not happen and HR ended up giving me a lecture on budget cuts instead. I stopped the meeting and left as HR had clearly lost the plot and said some very personal insulting things about me. I reported this to my union and sent a copy of my version of the events to SLT. Initially they made noises about having a meeting with HR and myself to move forward. She is now refusing to meet with me and SLT will not discuss it. My union rep is great but I feel like he would prefer me to just leave it. I am torn between leaving it and fighting my corner as I feel that my mental health was used against me and that this is so wrong. What would you do???
