Management of schools is down to the teachers, the headteachers and the governors. They should not wait for the government to tell them what to do. Schools have been prattling on about how difficult it will be to reopen ever since they were closed and if the supermarkets had behaved in a similar fashion we'd have all starved to death by now.
This country needs to get a grip. Its economy has been holed below the waterline and our institutions and way of life is beginning to disintegrate. Life cannot be put on hold until this virus disappears completely. In fact it never will and there are still remnants of the 1968 "Hong Kong 'Flu" still in circulation (during which pandemic, incidentally, there was no "lockdown" or even talk of one). Opening with a "new normal" is not sustainable in schools, pubs, restaurants, bars, dentists and public transport to name but a few activities. Life must return to normal - the old normal - and continually harping on about whether 2m or 1m is best for "anti-social distancing" is pointless.
I was speaking to a lady today whose son has been told that his GCSs are cancelled. Instead he will receive assessed grades. He has been off school for almost three months and he faces at least another three months at home. He is beginning to misbehave (whilst his mother has to work as she works for Tesco's) and who can blame him? Huge problems are being stored up by closing schools for six months or more and the problem is simply dismissed as if it's a couple of extra days off (e.g. "I very much doubt 6 months of non schooling for a 6 or 8 year old is going to make any difference in the long run"). You'd be surprised what a difference it makes and we are treading on very thin ice.
