Whos going to look after the teachers children if their parents have to work odd INSET days here and there and their own school isn't open.
Any variations to a well established regime have consequences. Michael Gove thinks its a good thing that free schools can set their own term dates but as most of us sensible folk know, its not such a good idea to break away from the norm. Only a few years ago did schools vary their Easter break so that some families had to take 4 weeks off school.
