Yeah, I get the socializing aspect and it hasn't been bad coming in. I've been wfh for the past like 4 years so it's nice to put on actual clothes instead of wearing joggers and t-shirts every day lol. You're lucky you're only required to come in one day a week. We have to come in 3 days (eventually we'll be monitored to make sure we come in 3 days) but at least we can pick the 3 days every week.
On the plus side, we have assigned cubes (no hotel cubes thankfully!) and since I was part of the first small group to come in, I was able to change cubes.
However, I still think it's BS that companies are forcing the back to work crap with such strict boundaries.
