  • Previous data from 1985 indicated over 94,000 persons engaged in shiftwork.

Purpose of the Study:

  • To assess the prevalence and patterns of shiftwork in Singapore's private sector.
  • To investigate the health implications and common complaints associated with shiftwork.

Main Methods:

  • A survey conducted in 1991 covered 4,996 private sector establishments with 25+ employees.
  • Data analyzed shiftwork prevalence, shift durations, and nightwork proportions.

Main Results:

  • 34.4% of establishments employed shiftworkers, totaling 206,965 employees (32% of the workforce).

  • A ten-fold increase in 12-hour shiftworkers was observed, alongside a trend towards permanent shifts.
  • The proportion of night shiftworkers decreased from 45.1% in 1985 to 36.9% in 1991.

    • Conclusions:

    • Shiftwork, particularly 12-hour and permanent schedules, is growing in Singapore.
    • Current studies show no serious long-term health effects, but further research is recommended for sleep issues and tiredness, especially in rotating shift workers.
