The question of how to lead, and what constitutes responsible leadership, becomes more stark and important in an increasingly unmanageable world. And as change has become our only constant, the answer is needed now. Based on decades of teaching, writing, and reflecting on leadership, Harvard Business School professor Joseph Badaracco addresses the question in The Good Struggle: Responsible Leadership in an Unforgiving World. Central to his argument is the idea of struggle and what he calls a "new invisible hand" of pervasive and powerful markets, both of which impact today's leaders more than they realize.
