They had to be dragged kicking and screaming to take any measures with schools and when they finally did they made the guidance so broad that pretty much everyone can qualify as a key worker.
Therefore schools stay open and busy but with no real lessons. Schools are now essentially child minding services and that's all.
It's never been about education. It's all about keeping the parents working for the economy. Fair enough, that's key as well, but i'm sick of hearing the government talk about children's education as if they give a shit. Nor is this a lockdown when schools are still busy and everyone is still going out to work every day, or wfh with less sympathetic employers.
