Workplaces are weird. Completely artificial environments filled with people who did not choose to meet and spend time with each other and, in fact, have to literally be paid to spend time in the same building as each other. What are some kinds or types of coworkers you have noticed in the years you have worked? I mean, the kind that, no matter where you work, there's always one of this kind. For starters: The coworker who works all of 20 hours a week but gets offended when she isn't included in every single conversation, either professional or personal.
