Public health and healthcare leaders have power, and they are also subject to powers out of their control. But many leaders in public health are most aware of the forces they must contend with to fulfill their responsibilities, and the limits of their power against those forces. The forces often include lack of funding, large and influential companies that value profit above public health, and other urgent population needs that render public health a lower priority. This chapter describes moral courage and how it fits into the larger field of ethics. It explains how to engender moral courage in the workplace and equip people to practice it and describes how public health ethics differs from medical ethics. The chapter explains how ethics can be taught and modeled to equip students with the knowledge and skills to practice moral courage.
