arisbottle, I have explained all of those points quite clearly and said that this is one suggested model for improvement.
If schools worked according to 6 week (or similar time scale) units then children and teachers could continue to opt for one of the 6 weeks as either a holiday unit where they would have the option of going away for the full 6 weeks or a leisure/extra curricular/catch up unit or a comination of the two.
This could be any six weeks during the year but only once a year.
Teachers could therefore continue to work under the model they currently have but with the flexibility of choosing their 6 week break when it suits them
OR
they could choose what would be my preference which would be to work the same number of directed hours but spread over more of the year (and therefore taking less holiday time). This would mean you would have less contact time or more frees during the working day and week, less marking and planning. This would be preferable for me because I could spend more time with my family in the evenings and weekends and less of my holidays working.
So, you see, under this model nobody loses out and everybody gains.
Parents and teachers who still want to take their kids out of school for 6 weeks get to do that (but there is no penalty for not all taking their kids out at the same point in the year) and parents who cannot or choose not to do that have the advantage of year round childcare in the form of education with a 6 week block of leisure/extra curricular etc activity.
