I had an office with a door for 12 years. I switched jobs 3 years ago and everyone has a cubicle even the managers. Constant distractions with people talking loudly on conference calls. Then someone else talks even louder on their call. Before covid our site was mostly working on the same project. There was some fun collaboration in the conference room around white boards etc. We had a reorg to pool resources across projects across the country so now only 3 out of 10 people on my project are at my site. Most of us bought our own 40" 4K monitors so if I go in a conference room I can't even share my remote Linux desktop session properly because I'm scrolling within the window to find my applications to share. Because of that I just stay at my cubicle to share my screen and end up disturbing everyone else around me with my own conference call. Everything would be fine with offices and doors but instead we get stupid surveys about whether we want an open floorplan which is even worse. We are supposed to go in the office 3 days a week. The reality is most people at my site show up once or twice a week for half a day for the free lunch once a week and then go home by 3pm to get work done. We have 30 job openings and we hire about 1 person every 2 months. We lose 1 person about every 4 months. Management hasn't said anything about people not showing up probably because they don't want to push people to leave.
