I'm fairly new to supply and I have just been given a supply contract for one term. I chose to do supply, as I feel that permanent teaching posts are too stressful for me at the moment. I am a little concerned about the workload, as I am expected to plan lessons and mark books/assessments. I understood this when I took the job, however, I am regularly asked to cover lessons during my free periods. Thus, I am forced to stay late after school to plan my lessons and finish my marking. I am in the same position as I was when I was a permanent teacher but with less job security and unpaid holidays. Is this an issue that I should raise? Or should I just keep my head down?
