People just don't get this. I was diagnosed mid thirties
Now imagine you trained to be a teacher, all you've ever done is teaching and people say "well now you can't do it any more, bye" and mid pandemic you have to look for a new job
It's basically saying people with X/Y/Z health conditions can't be teachers and fuck you if you're a teacher and get cancer
If I was a regular classroom teacher and had to go on chemo, I'd look into safer alternatives until my immune system was functioning again, like tutoring one on one or small groups. That's not ideal in income terms for however long I'd need to do that, but as careers go, teaching is generally highly income secure---much more so than most professions I know of. Expecting it to be 100% copper bottomed AND virus free is maybe expecting a bit much?
I do a 100% WFH job, self employed. Lucky me, in some ways. No particular risk of COVID and I could do it even if immunocompromised.
But I have zero job security EVER. If I do not work, I do not get paid, my pension does not happen. During the pandemic, I had to stop work for long periods several times due to lack of childcare and schooling. I ended up digging deep into savings, which veered close to zero at one point. I had to stop paying into my pension for quite a while. My income is still far lower than it was pre-pandemic due to the clients I lost and the pandemic's effect on many industries.
My friends who are teachers did have to navigate COVID risks, but on the other hand they got paid their salaries and pensions in full throughout.
My point is not "teachers are lucky" but rather that all professions have upsides and downsides.
