I feel like the biggest hinderance to making the most out of a remote option are the ones who prefer going to the office or explain all kinds of issues with "it's because we don't meet in person".
One just have to embrace and apply the mindset that it is possible. Different, surely, but still possible!
I'm not saying there is something WRONG with going to the office, it is lovely to hang out in person with lots of people, but it is very limiting in many ways as well. Just limiting in other ways than remote. You learn to deal with both, when you need to, though. The issue is mostly that people deal with the office-problems but don't care much about dealing with the remote-problems.
That feels like something that absolutely can and should be operationalized* if the success of the company relies on it. Build in easy ways for people to join other teams for a quarter (or whatever), ensure that areas of effort are communicated horizontally and back down in minimally invasive, synchronous manners, have clear domain ownership such that it's easy to know who to reach out to, etc.
It's absolutely bizarre to me to pin success on "employees chatting by the water cooler" or whatever the expectation by upper leadership is when they claim stuff around in person. Don't get me wrong, I like seeing coworkers in person now and again, but I explicitly want to do it just to meet them for socializing and team building; not working.
*(buzzword) Bingo!
I remember distinctly overhearing our internal devops at one place (that was pretty fragmented) talk about how their mandate was to get people only 80% of the way there, that the teams were responsible for getting 100%, and it pissed me off no end, since one of the reasons my department was doing our own devops was that there was no way to take what the devops department was putting out, and leverage it to get to what we wanted (i.e., no path to go from the 80% they provided -> 100% of what we needed). We had tried numerous times to talk to them about it, but they wanted to decide things in isolation and tell us what to do, rather than listening to us. I tried figuring out who was in charge of that group and reaching out to them, and managed a meeting, and they heard and acknowledged the need and agreed change was necessary, then nothing happened with it. Etc. None of that helped my morale, and I ended up leaving that company, not because of that, but because of a number of places where I simply could not affect change.
As a remote employee though? Don't care. As I said, that missing cultural buy in is a feature, not a bug, and it benefits everyone involved. I'm still raising concerns, still trying to reach out for solutions, but invariably when the business prevents me from fixing things I'm not stressing, and am so less likely to leave.
You can keep your magic, I'm gonna stay in my home office.
