So you think enough teachers will die or be off longer than two weeks that we won't have enough teachers and schools will close? Yeah. Seems really likely.
People do have really short memories.
In the week before schools were officially closed, in March, a very large number of schools were already partially closed due to staff shortages.
That period was short because we moved to full lockdown.
Had lockdown not come in, we would have had very few schools able to open properly anyway, due to lack of even vaguely qualified adults to do crowd control in front of each class.
There just aren't lots of 'spare teachers' waiting around to stand in front of classes just to keep schools open.
I am in a bubble of over 30, very closely linked to two other bubbles of the same size. A couple of cases within those 90+, and we're all at home. then i come back in BUT my DD, who is in a big bubble at sixth form, gets it and I have to stay at home as her close contact. Then my DH, who is in an even huger bubble as part of a sixth form (3000 all told), gets sent home with symptoms and I have to isolate again. then DS's uni closes due to a spike in cases, of which he is one, and I again have another two weeks.
So all without me being ill once, I end up at home for at least 8 weeks. Avery one of my colleagues could write a similar set of links through which they could easily be in self isolation for long periods.
