Earlier quoted context omitted.
>I will note that although I have never met an asshole who was a top performer, I have met many who were convinced that they were. Definitely this. I find that insecurity also correlates strongly with the above description.
So what do you label someone who does most of the work while other contribute little to nothing? How to they profess that and not be labeled an asshole?
In the case where the individual truly is more talented they don't need to profess it aggressively. It will be quite clear in feedback from colleagues to their boss and by the quality of the their output.
