A few weeks ago, my head told all the teachers what year group they will be teaching in September. Our school likes to mix it up every few years so always let people know well in advance. As I am head of year, I was told I was staying in my current year group. This was until I told my head I am pregnant and will be going on maternity after we break up for Christmas. I have now been told I will be a cover teacher for the autumn term. Are they allowed to do this? I know some people would like this as it doesn't come with all the responsibilities a class teacher has but for me, it sounds incredibly stressful- teaching different children all the time and working off other people's planning is my idea of a nightmare.
