Covid surge and a new job.

Reason this with me. I am sitting in a small office Friday with 3 people, in a small room that holds about 36 people (3 per cubicle, 2 or 3 per office) all having to wear masks but the whole job is talking on the phone, expelling breathe. I am sitting in this office with two others, door closed. The gal that is training me, while wearing a mask, though some times pulling down and speaking out or readjusting and touching everything tells me.... I do not have a vaccination. As a matter of fact, I have been trying to get covid for the last year an half.
Small office, door shut for 8 hours listening to her answering calls and helping customers trying to get info on covid testing sites and vaccination, and ya, other health issues. 8 hours in a small room, no ventilation telling me she is trying to get covid.

I mean, I get I have to go back to work. I get UI can't be forever. We have morgue trucks pulling into hospitals to refrigerate the dead because too many dying and being overwhelmed in funeral homes.

What do I do with that? A year and half, not seeing boys, not going out, doing all the things I need to do to not get covid cause I doubt my lungs could handle it, though the rest of me is healthy and weight on my side, though blood type not on my side.

I cannot talk to the 30 something young boss having only just been hired. Who knows? He might not have been vacc'ed either and think it his right. Just where do I put this and walk into the office tomorrow?
