  • Natural experiment (workers already in job roles).
  • Two groups of workers:
    • Skilled finishers, whose work rate determined the pay levels for the whole mill.
    • Unskilled maintenance and cleaning workers with more flexible working conditions.

Records kept

  • Daily urine sample – 4 times a day, baseline was at home.
  • Body temperature measured, caffeine and nicotine consumption.
  • Self-rating scales on words such as ‘sleepiness’, ‘well-being’.
  • Records of illness and absence.
Illustrative background for ResultsIllustrative background for Results ?? "content

Results

  • The skilled workers had increasing levels of adrenaline throughout the day, had higher body temperature and caffeine and nicotine consumption on work days compared to rest days.
  • They were more likely to self-report lower levels of well-being and had more days off due to ill health. All these things are indicators of high stress.
Illustrative background for Conclusion Illustrative background for Conclusion  ?? "content

Conclusion

  • The finishers were more stressed because of the following factors:
    • Responsibility for setting the wage rates.
    • Skilled but monotonous and repetitive work.
    • Machine paced work = absence of control.
    • Working in isolation.
