Emotional Intelligence (EI) is a highly effective skill that nonprofit leaders need to embrace, develop, and display mastery in their external world. This chapter explores the core components and competencies of EI, how it is measured, and how it can be applied by leaders in the disability and mental health sector. Examples of successful nonprofit leaders who display EI competencies are discussed. Some of the challenges that they face in developing their EI are presented and suggestions on how to lead through change and uncertainty are offered. Specific change and uncertainty scenarios are discussed, especially when operating in what anthropologist and futurist (Cascio in Facing the age of chaos. Medium, 2020) describe as a brittle, anxious, nonlinear and incomprehensible (BANI) world. This chapter concludes with a compelling argument for why EI is critical for the current climate in which nonprofit leaders operate. EI is the future of nonprofit leadership. A growing body of research points to the crucial role that EI plays in leadership performance, more engaged teams, increased resilience, better decisions, being more open to change, and boosting motivation. There is no doubt that resilient, compassionate, and effective leaders are needed by our nonprofit organisations and employees who are passionate about meaningful purpose filled work and positive work cultures.
