During covid my employer got rid of our office. We now use a much, much smaller office space shared between about 20 teams where you hot desk, and there's only 3 meeting rooms that are fully booked up months in advance, and no smaller meeting rooms or private spaces.
Therefore 95% of meetings are still on teams. The open plan office space is a nightmare for teams meetings, background noise is picked up really easily, so you have a situation where people go into the office to catch up with colleagues but are constantly told to be quiet because someone else is presenting on teams. So you end up just sitting there in near silence or on teams meetings - you might as well be at home.
Also a lot of the time the IT equipment doesn't work, or you have a chair that is jammed and won't adjust, or you can't connect to the WiFi for some unknown reason, so you spend loads of time faffing about getting it sorted.
Also little things like no supplies in the kitchen (coffee and tea etc) unless you bring it in yourself every single time, we used to have a kitty and rota for this when we had our own office/desks.
We don't have a return to the office mandate, so I only go into the office when I have a face to face meeting because there isn't much of a benefit otherwise.
