Developments in communication and information technology have an immense impact on all facets of life. These changes have led to an increase in the causes of stress that people are encountering today and this situation inevitably affects individuals physically and psychologically negatively. The concept of stress is likely the most important of these negative impacts that affect individuals in a wide range. Stress, which has evolved as a result of technological developments in recent years, has an array impact on both organizations and individuals. The technological change and adaptation process that organizations are undergoing can have a negative effect on employees, and stress brought on by technology can affect employees' performance. In this research, the dimensioning of the stress levels of the employees and the effect of this situation on the employee performance are discussed from the perspective of globalization and technological developments. The survey technique used in qualitative research methods was preferred in order to collect information from the research participants in line with the study purposes. In this context, the research sample consisted of employees working in different roles and positions in an enterprise operating in the private sector. In the light of the findings discussed within the scope of the research, it has been determined that organizational stress affects employee performance in many ways in terms of individual and organizational aspects, and there is a significant (psychological and mental, organizational role, organizational structure and business environment) relationship between them. However, it should be noted that in the research, there were also findings in which organizational stress did not have a significant effect on performance (relational and social, external environment and job qualification).
