I think it will end up with people who need to send their DC to school because they cannot work from home sending them back, and needing to. People need to work away from home. Others can stay at home and state employees get paid whatever.
There is the huge problem that government fully funded furlough will end. Companies are drawing up redundancy plans. People who cannot return to work due to no childcare will be made redundant. Their jobs won’t be needed, because they haven’t been for 8 weeks, and then they are not present in the future to do them either. So why would a firm keep those jobs open?
Schools could operate in smaller numbers from church halls, museums, theatres and open spaces. Other countries are doing this. The DC don’t all return to the same building. They spread out. We need a bit more flexibility.
