Letter sorting machine operators were investigated in a presentation to the 1981 International Conference on Machine Pacing and Occupational Stress. Fifty two employees at a post office who had no prior experience with the letter sorting machine completed a questionnaire that included items related to the person, job environment, job satisfaction, moods, and health. Over a 4 day period, fasting blood samples were collected for analysis, a 24 hour urine sample was analyzed for catecholamines, and a physical examination was performed. Subjects were divided into groups with two or three years experience and were compared in terms of questionnaire and biochemical results. Job satisfaction decreased linearly with years of employment while boredom increased linearly with time. The group with more sorting experience had higher scores for anger and hostility and depression and rejection. Variations in biochemical results tended to correspond between groups with no observable trends for either group. The author concludes that the results of biochemical evaluations do not provide any clear insight concerning the physical effects of changes in moods and attitudes.
