> For example, when I got a new boss and all the underlings went to them and start chatting about the boss's favorite sports teams and hobbies to get on their good side. I refused to do that. I'll be friendly, like any other new hire.

I don't know if I would consider this to be only getting on their good side. In many cases, if I am going to spend a significant amount of my life working with someone, I do want to get to know a bit about them and that includes their hobbies and interests outside of work. To me, that is being friendly and I also do that with new hires.
