Wife started back yesterday, today is the first with kids. The year group 'bubbles' are each over 200 kids, she will flit between all of the bubbles as she teaches secondary. I give it a month at most before the school will have entire bubbles at home. From what I saw cycling my son to school this morning, social distancing is not a thing, they were licking each other before they even got into school. Good luck to all involved, I guess at least the schools can say they tried when it all goes wrong.
