In this best-selling book, Kouzes and Posner (authors of The Leadership Challenge), explain why leadership is above all a relationship, with credibility as the cornerstone. They provide rich examples of real managers in action and reveal the six key disciplines and related practices that strengthen a leader's capacity for developing and sustaining credibility. Kouzes and Posner show how leaders can encourage greater initiative, risk-taking, and productivity by demonstrating trust in employees and resolving conflicts on the basis of principles, not positions.
