I have been working 1 day a week in the office through most of Covid. I am in a cubicle area where prior to Covid 6 people could sit. When I go in on Thursdays there are only 2 of us in that area. At this point I have stopped wearing a mask in the office as I feel safe with the current set up. When we have a meeting in the conference room with more than 4 of us I always put a mask on.
