Most teachers, in schools across the country are just getting on with their job and are extremely good at what they're doing.
The implication here would seem to be that the OP is not 'just getting on with her job.
Covid is here to stay and will flare up in waves for the next few years or even decades. If being around children feels too unsettling and unsafe it's probably sensible to strata looking into changing careers and looking for jobs that allow ex-teachers to WFH rather than expecting schools to close so they can WFH.
You're setting up a false binary. Teachers are asking for mitigations to help keep schools open, and to protect them and their students. Suggesting that teachers should change careers because they are scared of covid is minimising, at best.
I suspect, however, it's not the classroom where people catch covid but sitting and chatting at lunch or socialising with friends. Of course there will be many teachers also, who have passed on Covid to their pupils, it's common sense. There is also the issue of super spreading and recent research suggests that younger kids are less likely to be 'vectors of transmission' due to the levels of aerosols they project.
This is all speculation, and once again seems like an attempt to minimise teachers' concerns. Pupils have always spread their illnesses amongst each other, and infected staff, and this is a novel virus.
I feel empathy for the teachers on MN who are anxious about being around 30+ families, I hope, seeing that Covid isn't going anywhere soon, these lovely people will be able to transition to alternative jobs where they feel safe and in control. '
Once again, patronising, and insinuating that the onus is on the teacher to leave, rather than for the DofE to problem-solve, lead and finance.
Now, you may not have intended to sound like an U4T ambassador, but most of that post reads like comes from their manual.
I see in later posts that yo7 are pro-vax & -mask, so clearly not U4T. So yes, I apologise for that accusation, but I hope you can see how I arrived at that conclusion from your first post.
