I have participated as a leader in many organizations where the leadership culture was just mean - ugly, where competitiveness, and destructive relationships stymied progress. There should be healthy tension and candid debate, but leadership teams need to practice communication, relationship building, emotional intelligence, and be aligned around common purpose to achieve organizational success. Senior leaders, chief executive officers, others need to ensure they are fostering the right environment for leadership otherwise all of that ugliness will trickle through the organization.
