Fully vaccinated or not, many workers are still required to wear a mask in the workplace. We can do a small thing to signal our solidarity with other workers, even if they don’t recognize it.
I tried going without a mask at Costco today but felt crappy when I looked around and all the workers still are required to wear them. I felt better and more connected to my fellow workers once I put it back on.
We've been out of lockdown for a year now. And depending on what areas (red, heavy trump country) you were in, the sight of masks could already be pretty scarce. Now that masking is almost entirely voluntary, it's definitely 50%ish or below even in blue areas, and I'm occasionally getting dirty looks when I wear one out in red areas.
