Lack of empathy has been a common trait among problem employees that were too good at their job to simply suggest removal.

My buttons are more around things like constantly making work harder for everybody else and then dismissing complaints or slowness because it works for them, but I have no illusions that this sort of selfishness comes in only one flavor.

My favorite games are teams. My favorite workplaces are teams. And while I've worked at lots of places, in big groups, I've only worked on a few Teams that weren't in name only.
