In 2008 or so I worked for a consulting company where most of the workers were remote. Eventually, they opened up an office where I lived. We were encouraged (required?) to come into the office a few days a week. We free parking, table tennis and a cooler stocked with pop and beer.
My teams were always remote but I found the social aspects to be beneficial.
This was basically sort of my experience wren my company turned hybrid
I'm sure I might have some undiagnosed attention issues but it became supremely hard to concentrate once at the office because of the open office plan and people constantly distracting me with questions or requests (I don't begrudge them this though). I had to essentially monopolise one of the office mini conference rooms to actually do any work. It got to the point of 3 days of the week essentially being close to useless because I'd get more done once I was back home. Not helped by the company hiring across the country and not having all the staff at office which meant we were still teleconferencing all the time
