It comes and goes. I always had the option of WFH, and prior to covid, did do once a week to focus on particular tasks without interruption. My team is spread across different offices in different countries, so we have done video calls for years anyway. Even local colleagues are spread across a fairly widespread area around the office so meeting for a quick coffee isn't an option.
Covid has meant I've got to know some of my more distant colleagues better, but I think that's mostly coincidental as we had a departmental reorganisation a few months before, which has meant working on projects where we had to collaborate more.
But I live alone, and at the height of lockdown, with no swimming pool, yoga class or evening classes, the height of my weekly face-to-face interaction was something like, "that's £47.52, please, card only." It's not so bad now, as I can go to the pool and yoga and evening classes are back on, and we can go to the pub. But it's not the same as catching up with people in the kitchen area, the passing interactions with people you don't directly work with, where information and connections are shared informally. And although I can and do chat with colleagues on Slack, it's not the same as bring able to lean over and say, "did I hear you are working on a problem with X? I had a similar thing last week and A told me to do this, " and that sort of incidental sharing/learning. I know colleagues in shared houses and in busy family homes have also been desperate to get back to the office from time to time. We all have different situations and needs, but my employer does recognise that there's value in incidental social interactions in shared working spaces, and that while some people are very happy to WFH permanently (and some were on permanent home-based contracts for a long time before covid,) it doesn't work so well for others, so the office isn't totally closed, and you can go in if you have permission- and once the current WFH guidance is gone again, will be expected in at least once a week. However, when I had been in before Christmas, it wasn't the same - far fewer people, and no one I directly work with most of the time, and our desks have all gone to hot-desking. Things will shake down in time, and managers see value in face-to-face meetings once in a while (including with overseas colleagues,) but it's never going to be quite the same, which has positive and negative aspects. And because we don't yet know just how or when it will be the new normal, it makes it harder to adjust and prepare for it.
