There are orgs where you ask another team for help unconditionally with your problem affecting the company and there are orgs where no one will help you, huge problems be damned and you can't even get your coworkers to cooperate without going to your (and their) boss.

That's not "working with other people" - that's office politics.

Good call. I am not referring to that though :) I mean scenarios like:

- Other director comes and says: why should we work with your team instead of rolling out the same product ourselves (and getting your team laid off)?

- Our director comes and says: your team is too slow, why? You should do X instead of Y. Z Is super urgent: cancel your plans and do it.

- Other manager: my team is better than your team! My people deserve a raise/promo/whatever more than yours.
