Politics is how people organise and group. There are always ploys for control and expansion. Politics is practically biology, there is a pecking order and it is inescapable. What determines in and out group varies but it is always there if there are three or more people present.
I think what you're describing, I'd describe as "organization," rather than "politics." When I refer to "politics" in this conversation I mean something along the lines of "performing actions that are not company-goal-optimized, or, potentially detrimental to other employees, in order to advance oneself."
