Hey guys, author here. I just re-read this post (it was originally from a Quora thread a couple of years back) and realized that it is not my best. I didn't take the time to discuss my definition of "asshole" nor took the time to do the topic justice since it requires more than a few bullet points ("The No Asshole Rule" devoted an entire book to the topic)! I will make some mods to flesh it out.

I have also discovered that the downside of writing about assholes in the workplace is that criticisms of the piece usually end with the commenter calling you an asshole.
