Work Psychology, the second volume of the Handbook of Work and Organizational Psychology, concentrates on issues related to the direct relationship between the worker and the organization and on his or her task or function. This could be termed the classical tradition of work psychology, including human factors, psychology and ergonomics. This volume provides a comprehensive update on new issues and studies in this core area. Subjects like safety, occupational stress, workload and absenteeism due to sickness are tackled. Chapters discuss particular types of workers on whom psychologists have focused attention more recently: the older worker, the unemployed, and the foreign worker. Moving away somewhat from the 'micro-world' of the individual worker, models of human economic behaviour and the development of social indicator systems are also explored.
