How many people do you know who are genuinely keeping the kids in isolation?
DH works in a supermarket and asked me why so many kids were still on half term as there are so many in the store,
I had a quick look at local figures and it would seem that several of the local schools have burst bubbles.
I work in a school and so far, we have been lucky. Any children off being tested have been offered live lessons on Teams and to be fair, most have joined in. Those without access to Teams have been dropped off work (and food parcels).
