A lot of people confuse being direct and honest with being an asshole.

To elaborate; To me, being an asshole means being mean spirited or verdictive without a purpose for the heck of it. On the other hand telling someone directly that their work isn't acceptable or that something needs to be fixed may feel harsh but it is absolutely necessary to cultivating a functional high performing organization. One of the biggest problems with large bureaucratic organizations is that no one is ever willing to say anything uncomfortable and thus none of the problems are ever dealt with effectively and they devolve into swamps of mediocrity.
