How long is your official half day? Looking to reduce my hours at work and perhaps do mornings only. Have been told that is possible but would need to be in school from 8.00 - 1300. A full day is only 8.00- 1530 so surely half would be less? lunch is 1200-1300 btw...
I would say 8.30-12 would be reasonable contracted hours, but you may of course choose to arrive earlier or stay later in order to set up or mark. I do supply and get paid the same for a half day - whether it's a morning or an afternoon - even though the morning is obviously longer. I think it's just the way it is.
I work three and a half days. No-one would complain if I walked out the door at 12 on my half day, but usually I choose to stay and get things sorted for the next week before I leave. I do my lunchtime club that day too as I don't have to go and teach straight after!
I view it like directed time. On an afternoon I can't just leave at 3.15 as the expectation is that we work til approx 4pm (except on meeting days), so I don't generally leave at 12 either. I do tend to sit and have lunch with the other staff too, once I've got my stuff sorted as that helps me keep up with the gossip and news.
