Cutting a long story short, I had a lot of time off sick with anxiety caused by a bullying HOD and SMT a few years ago. I relocated abroad to teach and an early finish (half-term) was negotiated with the UK school, along with an agreed reference. I've had 6 job interviews to start in september, was successful at 1 but they called my previous UK school for a phone reference and consequently withdrew the job offer on the grounds of my sickness record being too high and "other issues raised". I'm now registered with supply agencies but haven't been getting any work despite it being available. Should I just give up now and look for a different career?
