The aim of this article is to present a descriptive view on the current developments in Turkish employment law regarding the impact of social media activities, which has gained significant attention due to the effect of digitalisation, on disciplinary processes, more specifically, on the termination of the employment contract. To this end, this review is structured around three headings. First, the content of the social media activities will be presented as an overview. Second, the relationship between the use of social media and the obligation to work (performance) will be examined. Finally, the relationship between the duty of loyalty and the employees’ social media activities will be discussed in connection with the termination, since disciplinary processes are closely related to it, which is the most serious and severe disciplinary sanction. Within this framework, the most challenging part of the conflict of interests is the determination of the limits of the employee’s freedom of expression and the employer’s right to manage. In this vein, the article aims to clarify the existing approach of doctrine and judicial decisions while highlighting the primary challenges faced in this issue.
