The Effects of Overtime Among Rotating Shiftworkers in the Oil Industry

  • Description:
    Objective: Refinery operators work extended shifts(12-hour), rotating shifts and increasing overtime rates have been reported. This study analyzes the effects of overtime on the frequency and intensity of shift rotation, and associated impacts on sleep, health, and quality of life indicators among the workforce. Methods: We administered a self-reported health questionnaire to refinery workers who were members of the United Steelworkers' Oil Sector in 15 states. Reported work schedules, overtime estimates, typical sleep schedules and an evaluation of sleep quality were used to estimate fatigue exposure. Self-reported diagnoses of cardiovascular disease, hypertension, diabetes, and gastrointestinal illness were used to calculate disease prevalence within the workforce. Job stress and quality of life indicators were measured and a depression assessment was performed. Results: Overtime was associated with increased numbers of shift changes, longer work sets, and fewer days off. Overtime impacted sleep quantity and quality. Poor sleep quality was associated with numerous mental and physical health problems. Overtime was highly correlated with recent GI discomfort, chest pains, elevated resting blood pressure, stress levels, and depressed mood. Individuals with more overtime-intensive work schedules also reported limited time for exercise and leisure, which correlated with elevated BMI and other chronic health conditions. Conclusions: The 12-hour shift, a compressed work schedule designed to offer more time at home, has affected many industries. But increasing rates of overtime diminish available recovery time needed to relieve work related fatigue. We found associations between overtime and decreased quality and quantity of sleep, with impacts on long term health and well-being. [Description provided by NIOSH]
