Imhotep,
Good for children to eat though, isn't it? Bloody money, who needs it?
As I have said before, possibly on this very thread:
NO country which has had an infection or death rate anything like ours is returning to a model of schooling that would allow parents to work full time, relying on school as their daytime childcare.
ALL have part time / part class / staggered schooling.
A class size of 10, for example, would mean that I would have to run 4 sessions to teach all of my class, and a quarter of a week's school is not useful for working parents. A strict cap of 15 would mean each child would get a third of a week's school. A child with COVID within the class would mean 14 days of quarantine for all.
It will have to be a little bit here, a little bit there - a few hours of socially-distanced schooling to allow a tiny bit of flexible working, and structures around furlough and wfh and benefits that allow this. Then a little bit more schooling allowing a few more hours of work.
Even that will require significant testing - so any teacher with a cough or temperature within their family can be tested and be back within a couple of days (if negative) and only off for a prolonged period if positive. it will require a bank of supply staff to cover positive / shielding teachers.
It will, above all, require numbers of cases in the country to be REALLY small, to reduce the probability of a case within the school to such a level that any school / class will remain open for more than a few days at fortnightly intervals.
