I think those things can help, but what seems to really do it for our team is a couple things: Don't hire toxic people. We had one interviewee who, when asked a question by my female coworker, would only talk to me, a male. It was quite obvious that this wasn't going to keep us working as a team. Allow social time. We have always had a freeform morning meeting that was supposed to be kind of like a standup, but we talked about anything and everything, and stopped when we ran out of stuff to talk about. One of our team went remote and that meeting went from something that Management didn't worry about to something that was mandatory to keep up the team. We're about a month or so in, and I'm happy to say that everything feels basically the same as before, just without that team member physically in a desk here. The real test will be when we next hire someone for the team, but that's a very infrequent thing.
