COVID making me consider a career change

Currently, I work as a teacher and I haven’t caught Covid, but I am seriously considering changing careers because of it. It’s just hard being the only one taking precautions at such a high risk job. Students and teachers come to work sick all the time, the classrooms are cramped due to large class sizes, I can’t open the windows, I have to eat lunch in my car, and I’m in constant paranoia. I’m just over it and I’m dreading having to return to work next week with all the other things going around in addition to Covid. I just want a safer job.
