UfT have gone utterly batshit.
That said, the idea that parents should have accepted 'blended learning' with a smile on our face and a spring in our step, at a time when cases were in single digits and the government was planning to reopen pubs, restaurants and cinemas, is really just ridiculous. What kind of 'conversation about flexible working' do you expect working parents to have with their employers? "Hi, please continue to pay me my full salary although I will be available for 20% of my hours"?
But the reason the government prioritised schools for reopening is not because of UfT, it's because they realise a) how important schools are - to children's life prospects, and to the economy of the future, not just to allow parents to work - and b) how limited their ability was to fix the damage caused by long-term school closures. If governments close private sector businesses, they can mitigate the damage a lot by writing a cheque. If they close schools, there is no cheque they can write to cancel out lost education and increased social inequality. There are no non-damaging measures to take, so they take the measures where they can mitigate more of the damage.
I know it became rather fashionable on Mumsnet this year to believe that schools were really just some kind of luxury babysitting service that parents were being a bit entitled to want in the first place, and all education could easily be delivered by BBC Bitesize, but schools are important. When Nicola Sturgeon said in Parliament yesterday that she was willing to close down even more of the economy to keep schools open, she was not saying that because she's scared of a Facebook group of anti-mask conspiracy theorists being mean.
