This has come up a lot lately. Riker was the worst example, but it seemed like the entire senior staff (minus Picard) had this problem to a lesser degree. They didn't treat outsiders well, and none of them seemed to have any friends away from Enterprise. Contrast that with Sisko's bunch, who had friends everywhere, and it's not hard to see why almost none of the TNG crew had assignments elsewhere during their careers (around the time of TNG's run). Only Crusher and Worf had other postings. When Riker finally left, he took Troi with him (and several other Enterprise crew members).
^O'Brien was an Enterprise transplant too, & there is some truth to the senior staff having old friends mentioned or creeping in on occasion, but with that said, it's kind of hard to disagree with any of the sentiments posted so far
I always found it weird that when Ro returned in Preemptive Strike
everyone was so welcoming, when ultimately, only Guinan, Picard & maybe Geordi, (a tiny bit in The Next Phase) ever connected with her at all

Riker was pretty much the lynch pin in the TNG command clique. If you're fortunate enough to be a member of their circle, everything's great. But if you're an outsider, such as Barclay, Ro, Shelby, Jellico, Lavelle and so forth he's in full condescending jerk mode. Even with his clone... well the second one. He killed the first one.
You can add Nella Darren to that list too, & pretty much everyone of the crew members featured in Lower Decks along with Lavelle, except maybe Ogawa. She seemed to fit in well enough
You do see some of the same faces showing up at onboard social functions, & celebrations too, which would seem to indicate that at least the other bridge officers got along well enough with the senior staff
