There are quite a few of us who have been teachers on here.
If only that helped with home learning...
There is more association of teachers spreading to pupils because they talk face on to pupils with a projected voice (plus the inevitable spittle/aerosol)
Apparently DS1's teacher (y5) had a phase of wearing a mask in class which I didn't realise at the time. He couldn't hear her, and his processing is not great anyway. She's switched to a visor, but it still bounces your voice back. I find it draining if I have to talk while wearing mine.
DS2's teacher (y3) has kept her face bare
Both DCs are front row, which I'm glad about because I want their teachers to check that they're keeping up with what's going on (DS2 is on his own planet, I'm not fully convinced that he's NT... mother says he's exactly like me at that age and that gives me no confidence as I'm still on my own planet
)
Children are less likely to show symptoms therefore less likely to spread than being symptomatic. They're more likely to show a range of mild symptoms common with any other winter bug rather than the classic temperature/ cough/ taste of adults and testing threshold.
I never was a great lover of the unions... when I did supply, there were several days of earning potential that I lost thanks to the NUT because schools don't take on supply on strike days to avoid being accused of undermining striking staff.
Shame they weren't this vociferous about all the stupid curriculum changes on no budget, and exponential growth of workload.
