Lipman-Blumen, a professor of public policy and organizational behavior at Claremont Graduate University, examines the seemingly inexplicable reasons why many employees are loyal to CEOs and politicians who abuse power, cook finances and otherwise virtually destroy their companies. Among the book's conclusions: employees feeling uncertain over their own job security will remain loyal to a toxic executive. Furthermore, economic turmoil, political crisis or company problems sometimes enhance the toxic leader's appeal. Using insights based on a psychological approach, especially Maslow's theories of self-esteem, Lipman-Blumen (The Connective Edge) offers numerous examples in both politics and business of toxic leaders who have survived crises and received accolades despite their obvious flaws. By using names familiar to many readers-Rudolph Giuliani; the former mayor of Providence, R.I., Buddy Cianci-the author is likely to attract a wider audience than if she focused on business executives. The book's strength is the detailed psychological approach to examining the phenomenon of loyalty to toxic leaders. The last section discusses how employees can recognize the signs of toxic leadership, but it doesn't offer enough practical steps on how to challenge these leaders. Still, this is a solid look at a dismaying business trend. (Sept.) Forecast: Endorsements from such notables as leadership gurus Max De Pree and Warren Bennis should boost book sales.
