Exactly this in my opinion. There is a galaxy of op-eds, federal govt weigh-in, angry debates all largely hinging on this premise being true or not but not admitting to it.

It's sometimes referred to as "not shitting where you eat". My coworkers are not my friends or people I want socialize with outside of a work settings. I keep it like that on purpose. That doesn't mean I won't treat my coworkers with the utmost respect while being friendly and kind, or that they aren't awesome people, it just means I like to keep my personal life separate from my work life.
