Extended workday schedules, like 12-hour shifts, are well-accepted by miners and improve sleep quality. Performance and safety measures generally show no negative impact from these alternative work schedules.

Area of Science:

  • Occupational Health
  • Industrial-Organizational Psychology
  • Mining Engineering

Background:

  • Shiftwork presents challenges across industries, prompting exploration of alternative work schedules.
  • Extended workday schedules (e.g., 12-hour shifts) are gaining traction in continuous operations.
  • Concerns exist regarding fatigue, safety, and performance with longer work hours.

Purpose of the Study:

  • To investigate the effects of transitioning to a 12-hour workday schedule.
  • To assess worker acceptance, sleep quality, and performance in an underground metal mine.

Main Methods:

  • A two-phase study was conducted at an underground metal mine.
  • Data collected before and after implementing a shift from 8-hour to 12-hour workdays.

Related Experiment Videos

  • Evaluated fatigue-sensitive behavioral and physiological performance measures.

    • Main Results:

    • Workers reported nearly unanimous acceptance of the 12-hour schedule.
    • Improved sleep quality was observed with the extended shifts.
    • No significant negative changes, and in some cases improvements, were noted in performance measures.

    Conclusions:

    • Extended workday schedules, such as 12-hour shifts, are viable and beneficial.
    • The new schedule was well-accepted and did not compromise worker performance or safety.
    • Periodic reevaluation of extended workday schedules is recommended.
