Introducing shift work risks productivity and safety, especially during night shifts. Optimizing shift systems by considering factors like shift length and rest breaks is crucial for mitigating these risks.

Area of Science:

  • Occupational Health
  • Human Factors Engineering
  • Industrial Psychology

Background:

  • Shift work is common in many industries, aiming to enhance productivity and operational continuity.
  • Concerns exist regarding the impact of shift work, particularly night shifts, on worker well-being and operational outcomes.

Purpose of the Study:

  • To review evidence on the effects of night shift work on productivity and safety.
  • To identify key factors influencing safety and productivity during shift work.
  • To provide recommendations for improving shift system design.

Main Methods:

  • Systematic review of existing literature on shift work, productivity, and safety.
  • Analysis of factors such as shift duration, successive shifts, and rest break frequency.

  • Synthesis of evidence regarding the combined impact of these factors.

    • Main Results:

    • Evidence suggests that both productivity and safety can be negatively impacted by night shift work.
    • Safety performance deteriorates with increasing consecutive night shifts, longer work hours, and reduced rest time.
    • The interplay between shift length and rest break frequency is critical; longer shifts with frequent breaks may be safer than shorter ones with fewer breaks.

    Conclusions:

    • Shift work, especially night shifts, poses risks to productivity and safety.
    • Improving shift system design by carefully managing shift length, work hours, and rest periods is essential.
    • A holistic approach considering the combined effects of various factors is necessary for effective risk mitigation in shift work environments.
