If you are promoting a culture of candor on your team, you have to get rid of the jerks. Many may think, “This guy is so brilliant, we can’t afford to lose him.” But it doesn’t matter how brilliant your jerk is, if you keep him on the team you can’t benefit from candor. The cost of jerkiness to effective teamwork is too high. Jerks are likely to rip your organization apart from the inside. And their favorite way to do that is often by stabbing their colleagues in the front and then offering, “I was just being candid.”
