I’ve been in post for 10 years, have spent much of that time shuffling things around to make my role what I want it to be. At the beginning of the academic year I finally had the job of my dreams. That has now come crashing down. A few years ago we had a colleague who started off fine but became an absolute nightmare. This person made me feel miserable with snide comments and unprofessional behaviour and the day they left was a huge relief. The person left and life at school improved immensely. Fast forward a couple of years and they’re back! And I simply can’t deal with it. I tell students all the time that in the real world they will need to get on with all kinds of people. To my shame I have discovered I can’t stand being in the same place... I saw the person in the car park this morning and almost just turned back home! I sound unhinged and immature which is embarrassing. I can’t go to our HOD because the two of them are best friends in real life. I don’t want to leave, but the current situation is unsustainable and I feel so powerless! I can’t adequately express how badly this person affects me. What can I do?
