I teach 3 days a week ( going to 4 days a week in sept) On Monday DH drops the children at childcare so I get to school at 6.30am, on all other days I arrive at 7.45,( but I wish it could be earlier) I leave at 5 or half 5. Most evenings I work for about an hour, but I try not to work on my days 'off'
I work a bit of sunday most weeks, but not for very long.
At different times of year e.g summer term reprot writing , home work is much more
I do not teach in the same school as my children, DH tries to take time off to see sports days etc and I dont work fridays when class assemblies tend to be, but otherwise, yes, I would miss them.
I have never been there for first days of school as it is also MY classes first day, so I need to be working, this is the only bit I feel guilty about.
The big advantage is holidays, which make it all worthwhile( but remember diff schools have diff inset days, dh takes these off)
It is not as straight forward as people think, I have had lots of friends say' oh,now the children are at school I will become a teacher, but all have changed their minds!!
If you do go for it, good luck, it can be a great job!!
