I do think school and bubble closures will lessen over the next few months. As everything settles down and we work out better systems, have better testing etc.
It was a big mistake imo to delay reopening schools until September when we know there will likely be a spike in cases in autumn/winter. Was crazy not to reopen fully in June and get some real experience/data.
It is reassuring the evidence is pointing to the fact this won't be due to schools reopening though. And as the professor says, closing them again should be a last resort.
The government will have to hold its nerve though as the unions will be shouting very loudly for closure as we see community cases rise I have no doubt.
2 things BoJo won't be able to ignore though are the economy (parents needing to work). And how difficult it appears to be to reopen schools! So I can't see it happening ever again. Plus the unions are in an incredibly weak position, press and public not on side, and large rise in unemployment.
