Each measure reflects the impact of an employee's work on a particular aspect of life outside the work setting. In both groups the greater the involvement of employees with their jobs, the greater the impact of their work on their nonworking lives. The policemen's jobs were more significant for their self-images, their choice of friends, and their leisure-time interests and activities. Despite being highly involved with their jobs, bank clerks' jobs did not have a strong impact on their nonworking lives. Thus, a high degree of involvement is necessary but not a sufficient condition for a high degree of occupational determinateness. Tables, 23 references, and a list of items on the job involvement scale are provided. (Author abstract modified)
