I work remotely at the moment since March 2020 and I'm over it, can't stand it anymore. I'm single with no kids and work a LOT. I'll frequently wake up, work twelve hours, go to bed, never leave the house. I'm looking for jobs in my field so I can at least get out of the house, go to an office and socialize a bit with colleagues and other office tenants, get lunch at outdoor cafes etc.
I also miss learning through osmosis from overhearing colleagues discussing technical concepts I'm unfamiliar with, and teaching others similarly about things I know that they don't.
My experience working with other people all fully remotely is that it's very difficult to coordinate as a group, and individually many people are terrible communicators. This is magnified by remote work. (Pet peeve: answer the phone and turn on your fucking camera, I want to know who I'm working 80 hours a week with ffs.)
All that said I totally agree that a lot of work can and should be done at home. A hybrid approach is difficult though unless everyone is at the office and WFH at the same time. Otherwise what's the point of me being at the office while you are at home and vice versa. It's very tricky and I'm not sure how to resolve.
