Socialisation is another thing, as is child care for those who cannot work from home
And childcare for those who can work from home. Because I can’t see how it’s possible to work from home while caring for and homeschooling young children.
I have been wfh since lockdown but DH and I have still had to take time off between us to manage childcare as there is absolutely no way i could do my job with dc around.
Also, if the schools close they would likely close nursery too, which will cause even more issues for working parents.
