I'm 10 years in, secondary teacher. I currently do 3 days a week, but honestly can't hack it anymore. The pressure and workload is too much. In particular behaviour at my current school is getting worse and worse, without any intervention. I have good behaviour management but it is exhausting.
I'm very seriously considering supply. We may be moving for Dh job, but even if we stay.
What is it like? Is it hard to have consistent work?
