Within the scope of the researches, when organizations position their employees according to their abilities and expertise, this can contribute positively to the performance and productivity of the employees. However, when the pressure is put on the employees, when the duties and responsibilities are given out of their knowledge, the desire to leave the organization starts to emerge. In other words, in cases of mobbing and role ambiguity, individuals who lose control feel themselves under pressure and unwillingly work while performing their duties. This situation also destroys the passion of the employees for their jobs. SPSS 25 and AMOS programs were used to analyze the data. Firstly, factor and reliability analysis were performed in the analyzes, and after these analyzes, correlation analysis was performed to examine the relationships between variables, and regression analysis was performed to test hypotheses. As a result of the research, mobbing and role uncertainty reveal employees' intention to leave and decrease their performance. Within the scope of the research model, data were collected from 321 employees in institutions operating in the service sector (logistics companies), and the relationships and effects between mobbing, role uncertainty, intention to leave and employee performance were examined.
