[Workers' subjective feeling of fatigue and attitudes towards work--effects of age and job difference]

The present study is an attempt to assess attitudes towards work and subjective feelings of fatigue. To discover the relationships between these factors, a field study was conducted in a large-sized electric company. The subjects were 1376 male workers. The results of the 30 questions concerning subjective feelings of fatigue published by the Japan Association of Industrial Health showed that the complaint rate of fatigue in younger workers (18-29 yrs.) was higher than that of older workers (30-66 yrs.). In the middle aged (44-49 yrs.), feelings of fatigue in the administrative group were lower than that of the non-administrative group. Finally, workers who had a high complaint rate of fatigue were less favourably disposed towards their work and felt an increase in boredom, loneliness and monotony. Overall, the results indicated that the difference of labor mode exerts an influence on the onset of self-reported stress.
