They called him Neutron Jack. They called him the world's toughest boss. And then Fortune called him ""The Manager of the Century."" In his twenty-year career at the helm of General Electric, Jack Welch defied conventional wisdom and turned an aging behemoth of a corporation into a lean, mean engine of growth and corporate innovation. In this remarkable autobiography-a classic business book and runaway New York Times bestseller now updated with a new afterword by the author-Jack Welch takes us on the rough-and-tumble ride that has been his remarkable life. From his working-class childhood to his early days in G.E. Plastics to his life at the top of the world's most successful company, Welch tells his intensely personal story with his well-known fire and candor. And although it chronicles billion-dollar deals and high-stakes corporate standoffs, Jack is ultimately a story about people-from a man who based his career on demanding only the best from others and from himself.
