It doesn't seem like schools have done much to prepare for the return of pupils. Compare how fast the supermarkets adapted and its incomparable.
While the supermarkets have to be commended, the differences in their situations (clientèle for comparison etc.) and how to deal with them are pretty stark.
Most people have been happy to go to the supermarket once a week, queue up for say thirty-minutes at staggered times and work on a one in one out basis.
Their staff, say except check out staff who have screens, have less close interaction with their customers and are allowed PPE in store. There's still a risk!
Yet, the government are wanting more people in, for longer periods, with less ability to stager and PPE pretty much not allowed. Adaptation is more difficult here.
In reality, the adaptation has come from online learning, which from my experience has been pretty commendable although it's probably not consistent.
