Job burnout and its influencing factors among coal dust exposed workers

Objective To explore the status of job burnout and its influential factors among coal dust exposed workers.Methods Maslach Burnout Inventory-General Survey(MBI-GS) was used to investigate 2 055 coal dust exposed workers.Results Workers in larger coal mines,with longer duration of underground work,longer dust-exposed duration,and longer dust-exposed time per day had much more heavy burnout(P< 0.05).The predictor variables of exhaustion included job fatigue(std b=0.188,P< 0.001),respiratory symptoms(std b=0.134,P< 0.001),benefits satisfaction (std b=0.124,P< 0.001),and social status of the job(std b=0.116,P< 0.001).The predictor variables of cynicism were social status of the job(std b=0.157,P< 0.001),benefits satisfaction (std b=0.151,P< 0.001),exposure years (std b=0.112,P< 0.001),and exposure time per day(std b=0.093,P< 0.001).The predictive variables of professional inefficacy were monthly personal income(std b=-0.096,P< 0.001),size of the firm (std b=0.095,P< 0.001),and opportunities to participate in recreation(std b=-0.082,P< 0.001).Conclusion To relieve job burnout of dust exposed coal mines workers,current work situations should be improved according to the main influencing factors.
