A survey of job stress and health complaints among United States Postal Service workers in machine paced letter sorting tasks (MPLSM) was conducted. Questionnaires that evaluated the relationship between machine paced sorting work and its effect on job demands and health complaints were sent to 12,300 postal service employees at 48 locations in the United States. Of these, 6,591 were MPLSM operators and 5,722 were non machine paced workers (comparisons). Approximately 6,700 useable responses, 3,176 from MPLSM workers were received. Machine paced workers reported greater job demands (high workload, work pressure and concentration, and memory demand) and decreased job satisfaction than non paced workers. MPLSM operators reported a higher incidence of visual, neck, and arm or hand health complaints. The visual complaints consisted of headaches, eye strain and blurred vision, and eye irritation. The authors conclude that the increased incidence of visual and muscular complaints of the MPLSM operators suggests that these might be problems related to environmental and work station design. An ergonomic evaluation of workplace conditions and design of the MPLSM positions is recommended.
