Peer pressure and the distaste for letting down a colleague will motivate a team player more than any fear of authoritative punishment or rebuke.

Therefore, it is key that leaders demonstrate restraint when their people engage in conflict, and allow resolution to occur naturally, as messy as it can sometimes be. This can be a challenge because many leaders feel that they are somehow failing in their jobs by losing control of their teams during conflict. Finally, as trite as it may sound, a leader's ability to personally model appropriate conflict behavior is essential. By avoiding conflict when it is necessary and productive — something many executives do — a team leader will encourage this dysfunction to thrive.

trust is not the same as assuming everyone is on the same page as you, and that they don't need to be pushed.
