If you recognise the nursery I'm talking about please don't out us all 
My 4yo attends a good nursery. Their pre-school bubble popped three weeks ago and all the children had two weeks isolation, all fine (if rubbish for us!)
4yo has been out of isolation for less than a week, with just three days back at nursery, when we're told the nursery is fully closing and all 100+ children must isolate. Obviously we pushed for a lot more information because why was the whole nursery closing, not just one bubble? Turns out that is because a staff member (unnamed but vaguely guessable given the explanations) who assists with seeing the children in in the morning has tested positive, and so PHE has decided this means all children have had contact and must isolate.
I'm really angry. Latest message from head office says 1) children should be collected by their bubble key workers unless it's really busy, and 2) management who help out during busy times should wear PPE. Neither of these things happen - no PPE on the one member of staff who checks the children in most mornings, and children are normally seen down to their room in mixed groups by whichever member of staff is free.
None of this bothered me at all because I thought it was such brief contact, mostly without any skin to skin contact. It's hugely busy with a long queue during morning drop off so I understand they are trying their best to keep the queue moving, but it seems in a way that is possibly breaching guidelines. But now it seems its enough to put a whole nursery into isolation, so it puts it in a whole different light.
Still having convos with head office about this but wondered what other people feel about this kind of situation?
