Maybe. That said, there are people in families who wouldn't do that. These examples aren't ones that prove or not that you act familial.

Would you do it for them? Come on, is taking no pay meaningless to you?

You missed the point of this thread, which is whether it's appropriate to call a company a "family."

Fair enough, I don't think it's appropriate to call a company a family.

I do however think taking zero pay is a signal which, under the right circumstances, is worthy of inspiring loyalty greater than the average company.
