Book excerpt: Badaracco (business ethics, Harvard) observes that the most effective leaders are rarely public heroes or high-profile champions of causes. His study of "quiet leadership," carried out over four years, presents a series of stories describing quiet leaders at work and drawing practical lessons for executives and aspiring corporate leaders. The cases include a hospital CEO dealing with a case of sexual harassment; a bank president under pressure to remove underperforming but longtime employees; and a high-tech marketing rep who learned that his company was dumping obsolete equipment on its small customers.
