Vocational burnout is defined as a psychological malady, or disease, likely to stem from certain pressure on mind as well as tough and stressful working conditions. In other words, it is thought to get exhausted both physically and psychologically mainly due to vocational (professional) environments. A relevant literature review reveals that vocational fatigue or burnout has been studied for various vocational groups. The ever growing trade volume has recently affected the growth of seaborne trade and thus shipping, which in turn has increased the work density at seaports. Hence, the working conditions at seaports, for those who have chosen to work at ports as their career, have become tougher and tougher. That's why the population sample for this study has constituted the employees of a seaport. The purpose of this research is to analyze the extent (level) of vocational fatigue seaport employees suffer from. For this analysis, "Maslach Burnout Inventory", one of the most prevalent fatigue-related inventories, has been used. In this research, the extents/levels of fatigue have been interrelated with the demographic data concerning the seaport employees, and the effect of the fatigue levels on vocational careers has been scrutinized.
