Employee retention has emerged as a critical challenge for private sector organizations, particularly in developing regions like Jharkhand. Beyond formal employment contracts, employees form psychological expectations regarding growth, fairness, recognition, and organizational support. This unwritten set of expectations is referred to as the psychological contract. The present study examines the impact of psychological contract fulfillment on employee retention in private sector organizations in Jharkhand. Using a descriptive research design, data were collected from employees working in various private organizations across manufacturing, service, and IT sectors. The study finds that fulfillment of psychological contracts significantly influences employee commitment and retention intentions. Breach or violation of psychological contracts leads to dissatisfaction, reduced trust, and increased turnover intentions. The study highlights the need for organizations to actively manage employee expectations and foster transparent communication to strengthen retention strategies.
