I have been a supply teacher for 20 years. It has been the worst term I have ever had. I have only had 3 days this term. In the last 20 years I was booked almost ever day. It is beyond ridiculous. The Government have ruined teaching as a profession, especially supply. It's time to leave. With a heavy heart after 20 years of teaching I realise it is now unsustainable to make a living out of it. Opinions welcome.
