I haven't read through all of the thread..
but just to say, I have no problem working longer days or having less holiday in theory.
However. As it currently stands, I'm at school 7.30am until 5pm. Then home, deal with DD, food, bed/bath etc, then work from 8pm til 10pm.
At weekends I work all day Sunday.
In holiday time, usually I work 3 days out of the 5 when it's a week holiday and for longer holidays (e.g summer) I work at least 9 full days planning and assessing.
In all honesty, I just don't see when I would get my planning, marking, assessing and all the other paper shit work done if the school day was longer and the holidays shorter.
I've worked in other professions. Honestly. It was easier. Longer days, longer weeks, less holidays but definitely easier. The paperwork is ridiculous in teaching and only getting worse.
