Environmental sustainability has become a strategic priority for modern service organizations. Green Human Resource Management (GHRM) practices integrate environmental management into human resource policies to promote eco-friendly employee behavior and sustainable organizational culture. This study examines the influence of GHRM practices on employee sustainability in Indian service organizations. Primary data were collected from 205 service-sector employees through a structured questionnaire. The study analyzes the impact of green recruitment, green training, green performance appraisal, and green reward systems on employee environmental awareness, eco-friendly behavior, job commitment, and long-term retention. The findings reveal a significant positive relationship between GHRM practices and employee sustainability, highlighting the role of green HR initiatives in building environmentally responsible and committed workforces.
