Feeling a little hard done by today and was wondering if I was being unreasonable. Yesterday morning I left for work extra early so that I could get to school to do a revision session for my maths class before the exam. I hadn't planned my lessons for the day as I was writing reports until 1am the night before. I was timetabled for my year 11 class (who were in the exam) period 1 so thought I would do the planning then. Seemed a fair swap to me, before school lesson swapped for period 1. On the way to school my car started feeling a little odd and the engine light came on on the dash. After paying for the husbands car to be fixed last week, I've no money left to fix my car this month so this started me off stressing. My daughter has also broken my glasses so I'm wearing an old pair until pay day so I have a consistent headache. I was then given cover for period 1. This would have been my first gained time that I had intended to plan in (all my others have been spent supporting other colleagues) . I was talking to work friends about it (yes, complaining) and then I suddenly felt overwhelmed by the stress and left so that I could hide in the toilets as I just wanted to cry. It wasn't the cover that had made me want to cry - it was everything else but as I went into the toilets I ran into the cover woman, at this point I was crying and it was a couple of minutes before the start of period 1. I said to her "I can't possibly do this cover this morning". She snatched the cover sheet off me and ran off. This morning I was called into the assistant head teacher office and made to feel like I was out of line for upsetting the cover woman. Am I being unreasonable to not see how I have actually done anything wrong? I'm currently in the NASUWT so shouldn't be doing cover anyway, never mind cover during gained time. I have done though to help out the cover woman - as I actually liked her.
