Are you sitting in a pod area with someone else all day? Or are all people separated by dividers?
I’ve been in the office full-time since June 2020. We have a large room with 14-16’ ceilings that is separated into 8 cubicles with 5.5’ tall dividers and some open common space. No mask or vax requirements here either.
Before vaccines were available, I was not happy to say the least. I brought in an air purifier for my space and I wore a mask with a PM-2.5 filter all day. I was the only one. We were supposed to wear a mask in common spaces, but most didn’t and it wasn’t enforced.
Once vaccines were available and case counts dropped, I dropped the mask and the air purifier. I do turn it on during waves such as omicron. I wear masks to meeting that I deem crowded. But if there are only 4 people in a large room and we are all spaced out, I don’t bother. I will add that often I am the only one masked in these meetings. Sometimes it bothers me, sometimes not. It depends on the day.
I would definitely wear a mask if I had to work in a small pod with someone else.
Edit - If I had serious health issues, I would also get boosters as soon as I was able. And, I would be in touch with my doctor to have a plan how to get the antivirals if I did come down with it.
