In my dismayed opinion,
REFUSAL to shut UK schools, keeping them open for up to three weeks until the Easter holiday
is deliberately treating teachers and school staff as expendable..
For a different view, it also continues mixing people (schoolchildren) with those they already mix with, rather than releasing them from those confines and allowing them to mix more widely.
Which is the correct line to take, I don't know. But whichever the government chooses I would not attribute dishonourable motives.
