The survey on occupational fatigue and burn-out between 8- h and 12-h shift workers in petrochemical industries

Abstract

Background and objective: The term “Shift worker” is generally used for people who are working at any schedule other than the standard daylight hours (7 am-6 pm). In addition to the many diseases are associated with shift working, it is one of the most common causes of burnout and fatigue caused by work, So, the aim of this study was to evaluate fatigue and burnout among 8 and 12-hour shift workers in petrochemical industries. Methods: Data were collected using a general questionnaire for the demographic characteristic as well as Maslach burnout inventory (MBI- 22) and multidimensional fatigue inventory (MFI-20). Result: Result of the study showed a weak relationship between the individual and occupational demographic characteristics on fatigue and burnout dimensions. 12-hours shift workers suffer more significantly than 8-hours from higher general fatigue, physical, mental, emotional, depersonalization and lower personal accomplishment (p<0.05). No significant difference was found between reduced activity and motivation in 8 and 12 hours shifts comparison (p>0.05). Only about 15% of 12-hours shift workers possess high personal accomplishment whereas 85% of 8-hour shift workers had a high level of self accomplishment in both shifts mental fatigue had the most correlation with depersonalization. Conclusion: 12 hour shift workers were most prone to job induced fatigue and burnout among the others and were suffering from personality difficulties. Job burnout is more related to mental linkedfatigue aspects and to reduce these factors, company management has to pay attention to employee’s hygiene levels, health and welfare.
