My experience is that it seems less common at start-ups, with the caveat that it's my experience and so definitively biased. At least the startups I've been in have been small, tight-knit groups where any socialisation have tended to be group activities, and where there's been little implicit imposing hierarchy, and standing up for yourself tends to be appreciated.

In larger companies, on the other hand, you get all kinds of weird little fiefdoms where getting on your managers bad side is potentially far more damaging because if your boss has sufficient support he will be able to musster a much bigger support system.
