It’s not necessarily that they dislike the people, either. It could be an issue if the other people/animals at home aren’t cooperative with your need to work, despite being lovely in normal home situations. It could be a total lack of cooperative workspace - no desk space, too cluttered, areas already dedicated to other home tasks, noisy neighbors, easy distractions, etc. And then some people are just wholly impatient, who can’t identify what they need to make their home space more like their office space. Personally, I played a bunch of video games in 2020. I felt I performed better overall because blocking off an hour of game campaign kept me off my phone most of the day. Now I sit in an office again, scrolling here for more than an hour each day.
But yes, I had a number of coworkers in 2020 that came back as soon as they could in order to get away from their families again. Work was their herculean daily task that gave them an excuse to be away from families and be too tired to engage with them after work. The kind that always joked “gonna go home, hit the wife, and fuck the dog”
It’s not always outright negativity, but it can be.
