A mandatory first month work from the main office, bi annual everyone retreat in one location or twists on these ideas might work for remote only setups.
Total surveillance only works for drones and monkeys hitting typewriters. Totally fine for a cash cow monopoly.
I started working full remote in 2018, and I found quarterly meetups work well. 3 days to 1 week on-site per quarter. I pack the week with in-person meetings/lunches/dinners with my customers, coworkers and management to get facetime.
This makes the person you're working with more than a drone, because you have the chance to touch to other person's life. The same is also valid for your colleague.
To be able to foster these kinds of relations, you need to share the space for quite some time. Humans are not machines, this is not a file transfer operation This is way working face to face, esp. in a harmonious team is always better than WFH. Companies are not always in the wrong for wanting their teams in the office.
Of course some people may prefer WFH more, for any number of reasons, and I'm no judge. However, claiming that F2F working conditions have no advantages over WFH is just not true, to put it very mildly.
During the pandemic, we have worked remotely for a year or so, and we were bloody effective. However, when I pondered about why is it so, I found out that because we have deep personal, one to one connections already. In other words, we can work effectively because we know each other very well, not only in work setting but in personal setting too.
When a remote team is assembled, the window for knowing each other is way narrower. You can work and put good results out, yes. We also do this all the time, because we work with many remote teams as a part of the said team, and we don't see them face to face for years sometimes, however when we meet with these people, even for a couple of days, our relationship and work performance changes.
Since we spend time together, we understand each other better and note our underlying characters, inside and outside work. This allows better relationships and faster, way more efficient work. Mails get shorter, things get more fruitful, and work accelerates.
WFH and remote work works, up to a point, but there's a glass ceiling. Some people may not feel or want to understand that, but it's there.
Face to face communication carries way more information than a webcam + microphone.
