I think I’ve seen either a similar or the same discussion now: I’m not on FB often.
Sorry, just couldn’t get my head around the discrepancy about working from home when we do it ourselves!
Having seen some of the comments, I understand a bit better now.
The thread I saw doesn’t seem to be a general condemnation about working from home, but more a discussion about the safety aspects in the current weather situation. Yes, it’s got heated in places!
One point is that the parents consider it too dangerous to drive to work, but not too dangerous to drive to the childminder with their child.
Another is around the school runs: the parent expecting the childminder to risk the other children by doing the school run instead of picking up themselves - I’m assuming that’s prompted by the death of the 7 year old in Cornwall.
Plenty of other childminders pointing out it’s our job and we’re being paid to do it 
I suppose it depends on where we are and how bad conditions are. Perhaps that’s the situation with the Op and her childminder is open, but won’t venture out.
It did seem strange for childminders to complain about parents working from home when so many of our parents do it!
