Supervisors' ratings of individual industrial workers appear to be related to the central life interests (CLI) of the workers. The group of workers who had a job-oriented CLI received the highest ratings from their superivsors among the three CLI groups on Initiative and Application, Cooperation and Quantity of Work and were rated low on Adaptability. The reverse pattern held for workers with a non-job CLI. Implications of these findings are discussed for their utility in interpreting supervisors' orientations in making performance evaluations, as they relate to the characteristics of employees and the characteristics of the rating system.
