I dread to think! It depends on the time of year. Around show week it's a lot, as it is around exams. Due to the extra bank holidays I'm going to have to go into school for one of them with my AS group as it's hitting so many of their lessons. I tend to do 5 lunchtimes a week Sept-March and I've been doing 2 after school sessions for the show and for my re-sit group. And then with coursework I'm doing extra sessions after school for controlled conditions. Also, we do a Sunday for the show and of course evening performances, for both extra curricular and exams. And of course trips, which all take place in the evenings. Having said that, my English teaching colleagues have *far* more marking than me so although they don't stay in school or come in on Sundays/Bank Holidays they probably spend the same amount of time marking at home. I don't resent it on the whole and I do think extra curricular is part of the job to be honest. For the exams and coursework, like most teachers at my school, I do what I can to ensure it's up to standard and this sometimes includes extra rehearsals and catch up sessions. It is hard though and it's something I've struggled to find a balance with and I find that I do less now than I used to - partly because I'm more efficient at using lesson time so there's less need and partly because I do draw a line. I do sympathise. My husband is a music teacher so he's in a similar position. I can certainly relate to the feeling of struggling from time to time though!
