The human fulfillment model views work as the primary means for people to develop their full human potential. It argues that through work, people can cultivate virtues like diligence, perseverance, and concentration that improve skills and character. Without work, people risk becoming apathetic. Unemployment has psychological costs like loss of self-esteem as well as social costs. The model claims that the right kind of work can foster human development and fulfillment by expressing our nature as social, creative beings.
