The book is a collection of original papers by leading authorities in various fields that presents an overview of what work and nonwork (productive leisure activities) have been, are now, and probably will be in the future. Concepts of work and nonwork are examined from several perspectives: historical, intercultural, institutional, and in the context of rapid societal change. All of the contributing authors agree that over the next 30 years work will become more diverse and challenging, individuals and organizations more adaptable, and institutional boundaries more permeable; work and nonwork will become less differentiable with more opportunities for increased work fulfillment. One suggestion is the creation of a resource conservation industry that merges society's needs for new kinds of work with human needs for more fulfilling work. Another author describes the uses of behavior modification in improving incentive management systems. New ideas are described in the area of human resource accounting, which promises to be increasingly important in the future. The concluding chapter focuses on change measurement technology that uses multi-faceted and continuous observational and measurement methods for rapid and accurate detection of the effects of social interventions.
