Employees’ individual performance is influenced by many factors, and empirical studies in various cultures and sectors are conducted on this subject. There is a need for empirical research to identify the predictive factors of individual performance in different cultures and sectors. In this study, the factors affecting employees’ individual performance were examined based on Social Exchange Theory. In this context, the purpose of the study is to reveal the effect of logistics sector employees’ perceptions of leader-member exchange on performance outcomes and to examine the mediating effect of career satisfaction on this relationship. Quantitative research methods have been used in the study. It was conducted through a survey on a sample of logistics sector employees (n= 409) operating in Türkiye. In the study, it was determined that employees with high leader-member exchange have high career satisfaction and individual performance, and career satisfaction has a partial mediating effect on the effect of LMX on individual performance. Accordingly, the effects of LMX on individual performance can be enhanced mainly by improving career satisfaction. Since career satisfaction ensures that employees are satisfied not only with their jobs but also with their career development, the positive impact of this satisfaction on individual performance is significant. Therefore, it is critical for the success of the organization that logistics firm managers give importance to the career development of their employees and be supportive in this regard. Limitations, future research directions and theoretical and practical implications are discussed at the end of the study.
