Bad idea all round imo.
Where is he going to find the money to resource all this extra time?
Where is he going to find additional staff to cover some of it?
The salary increases is not just teachers - but TA, dinner staff, school patrol crossings, office staff, caretakers...
It will also cost more in heating, lighting, electricity, school resources...
Children will need feeding if there til 6pm - who/where/when?
It will not reduce summer holiday prices either. They will not reduce as holiday companies know most people will still holiday inthe summer. But the 3 or 4 weeks holidays will get higher again.
Imagine you work in an office and everyone is a parent. How do offices make sure everyone gets their time off but still mans the office? Can they all get it in those 3 or 4 weeks. Because no one really wants to go on holiday in the winter unless they can afford long haul. So then you see term time holidays increasing and unauthorised absence increasing in schools.
Not to mention how shattered children already are come 3:30pm or after a 7 week term.
Won't affect my DD - she goes to an independent school. She already has 3 additional weeks holiday each year. Strangely doesn't affect the academic results in those schools nor the way the children learn.
IME DD never gets bored in the longer holidays.
Maybe the Government should just actually leave stuff as it is, stop changing the rules every year, leave the curriculum alone for a while and let teachers teach.
Things don't work as they are introduced, given a year and then changed. Nothing is ever given proper time or resources to actually kick in and work.
