Are you now, or have you ever been a "company man?"?

By “company man” (I’m using the historical term, but I mean to be gender neutral—another way I think of it is as “thinking with your organizational head”), I mean a person who places the organization ahead of themselves. They think as if they were the organization. They try to get others to think that way, instead of for their own personal interest. They buy into the whole culture and philosophy of the organization. They are a cheerleader for the organization.

Have you ever done this? Are you doing this now? How does it feel to do this? Are you comfortable wearing the company hat, or does it sit heavily on your head. Why did (or do) you do it?
