Healthy Work is a classic--though currently under-appreciated--work on organizations. It is a book of great breadth and richness that deserves more than one reading. Healthy Work is a "must read" for those concerned with creating healthy organizations. It describes the demand-control model, which has had a huge influence on research on work and health. The model was prompted by Karasek's concern about the consequences of demand-control imbalances in the workplace. Karasek and Theorell provide a vision of humane organizations in which employees can master challenges and experience personal growth. Healthy Work is not an easy read, but it is a "must read" for OD practitioners, OB professors, and those concerned with improving life in organizations. It challenges us to improve the "psychic prisons" in which many employees--unfortunately--spend much of their waking hours.
