I think schools are unlikely to close again in the UK (and in the country where I live, probably zero, thank God).
If we did have another school closure, honestly, I'd be talking to my friends with kids in the same age group and arranging for the kids to go round each other houses, one per day, in a rota, so that only one parent in the group has to stop working on any given day to supervise the kids and help with their studies. That is kind of what me and a group of several friends wound up doing by the end of the 10 week schools closures we had over here in spring 2020. It massively improved the kids' studies, the adults' ability to work, and everyone's bloody mental health. There was never any full lockdown here, so there was no practical way to stop people "podding" the kids' education like this.
Yes, it does rather render the effect of the school closure minimal to nil, but if schools really did close again, well, I think I've kind of reached the "fuck it, I'm beyond caring" point, IYKWIM?
