I personally use "We" which is not mentioned. Awkward. (In French we have "On" a sort of informal "We" and mix between first and third person without equivalent in English).
e.g. "We don't do things this way." vs "You're not meant to do things this way." or "We think it's best to let you go." vs "I think it's best to let you go."
[0]: Not saying that this is never appropriate, but in many cases this is just used as a tool to shift personal responsibility onto the entire team/company or present subjective opinions as something everyone agreed on. Team-building isn't something you can just define into existence.
TL;DR: 1) a very close analog to (pronoun, non-numerical) "one" in English, 2) an informal stand-in for nous, that is, "we", as in on y va[1].
I'm not completely sure now, but at least i'm not wrong.
