I have always abided by the rule- never get up before 7am and never go to bed before 11pm. Find a job that is close by therefore. 7.15 Arise 8am Leave home 8.05 Arrive and switch on computer. 10.40 - 11 Break in staffroom, tea, chat. 12.30 - 1.20 Lunch in staffroom. 3.20 School ends 3.40 / 4pm Leave school Mark in free periods and 30 minutes after school. No work in evenings or at weekends except when GCSE and A level mocks need to be marked. I managed to run a secondary dept with excellent results and only worked 1.5 hours for 3 evenings per week for years. Duck and dive, find a way or find another job.
