Based on the Supply-Value fit theory (SVF), this study aims to investigate how green human resources management (GHRM) impacts employee well-being and engagement with environmental initiatives in the healthcare sector. The study looked into the aspects of green human resources management in the workplace, focusing on the underlying mechanism of employee green behavior. Further, the study also proposes the moderating role of individual green values. The study used a quantitative research method with a random sampling technique and gathered data from 402 nurses working at leading hospitals. The statistical technique used to assess the study's hypotheses was partial least squares structural equation modeling (PLS-SEM). The results support a link between green human resources management and employees' green behavior, well-being, and engagement. Similarly, the results support mediating and moderating effects of employee green behavior and individual green values. Therefore, the findings offer policymakers in the healthcare sector of developing countries valuable insights into how green human resources management may improve employee well-being and engagement with environmental initiatives.
