if most other professions have gone back to normal I don't see why schools and teachers also can't.
Only someone without kids in school could write this.
Schools HAVE been back 'as normal' since Sept 2020 pretty much with much fewer mitigations than in the rest of society. The only time they weren't back pretty much as normal (particularly primary) was when the lack of mitigations elsewhere and piss poor management of covid caused cases to overwhelm hospitals and force a lockdown in early 2021. Even then, most kids seemed to be in school.
And 'normal' in schools is an underfunded, crumbling system, where vulnerable kids fall through the cracks and there is an increasingly demoralised (though amazing) and stretched workforce. With school buildings crumbing and the amount spent per pupil steadily declining, where parents are increasingly asked to step in to buy essentials which were previously paid for by the state (e.g. our PTA recently bought a load of reading books).
It emerged recently that in my daughters Reception class the materials such as scissors, paper, pencils and card were being purchased by the teacher and TA out of their own money. We parents did a quick whip around and gave them some money as they're not exactly paid a fortune (unlike MPs).
It's a national disgrace and the Tories should hang their heads in shame.
