Poor and ineffective leadership is evident in all spheres of life, especially in business. A possible reason for the current leadership crises is the application of ineffective and self-serving leadership practices that only aim to achieve selfish and short-term objectives at the detriment and longevity of people, business, society, as well as the environment. This book proposes a more effective and proven leadership approach to sustain people, business, society, and the environment, namely servant leadership. It describes the dimensions and functions of a servant leader in detail and provides practical resources to apply servant leadership in any organization. This book also provides several systematic leadership frameworks to empower people and to build high performing and significant organizations. Leaders, consultants, and practitioners can use this book as a guide to implement servant leadership in a company to ultimately create a more profitable, significant, and sustainable organization.
