According to William Ury, it takes two sides to fight, but a third to stop. Distilling the lessons of two decades of experience in family struggles, labor strikes, and wars, he presents a bold new strategy for stopping fights. He also describes ten practical roles--as managers, teachers, parents, and citizens--that each of us can play every day to prevent destructive conflict.Fighting isn't an inevitable part of human nature, Ury explains, drawing on his training as an anthropologist and his work among primitive tribes and modern corporations. We have a powerful alternative--The Third Side--which can transform our daily battles into creative conflict and cooperation at home, at work, and in the world.
