Part of building relationships from a management perspective means understanding how people operate, and then helping to create an environment that’s conducive to them. Your responses in this thread read like you expect everyone you work with to instead meet you on your level. That’s great when everyone is like minded, but as teams scale up it doesn’t work that way.

I also have many ex-coworkers who are great friends. I have others who are doing great and I only see random updates on LinkedIn every few years as they move around. Both are fine, both sets of people were awesome hires (on a remote team)
