Also hate it, but for slightly different reason to the OP.
Today, I had my first day back in the office since March 2020. We are being "forced" back in by our practice manager, which goes against the corporate policy of "continue to work from home if possible". She has not given us a reason for her insistence that we return, other than to "reconnect and network with other teams". We are to go in one day a week each.
Today, I was on my own. No one else from my team.
I found that I have become hyper-sensitive to the noise from other people. Those around me weren't being particularly loud - I was just very very aware of it. I found it very distracting and found it very difficult to focus on my own tasks. I found that I couldn't help listening to everyone else's phone calls and conversations.
Also - although our team were asked to do LFTs the night before going in, I have no idea if anyone else in other teams had done them. I have no idea if anyone else has been double-jabbed.
All in all, it was a horrible day. I "reconnected and networked" with a total of four people, and exchanged short pleasantries with two other people I've never seen before and likely will never see again.
Our own team communicate extremely well via "Teams" messages and calls and a team WhatsApp group, and in fact, I have got to know several members of our section this way. People that, because of the layout of the office (and the punishing workload), I rarely got to talk to whilst in the office. No need for us to be in the office building at all.
