I am being asked by my team leader to teach from 1-7pm without a significant break - so two teaching sessions 1-4pm; 4-7pm. Students have a 15 minute break within each of these slots. I will be working on admin etc from 9am to 12 that day. Is this legal? Can I say no to him? I live an hour and a quarter drive from work so won’t get home until 8:15pm at the most on those days and I’m usually in bed by 9pm to cope with menopausal night wakenings. Really don’t want to do this.
