The Psychology of Green Work: How Green Human Resource Management and Voluntary Workplace Green Behavior Shape Organizational Identification Through Green Psychological Climate and Green Passion in Healthcare

ABSTRACT This study examines the relationships between green human resource management (GHRM), voluntary workplace green behavior (VWGB), and employees' organizational identification (OI), while investigating the mediating roles of green psychological climate (GPC) and green passion (GP). The study employs a cross‐sectional design based on survey data collected from 288 employees working in a Turkish healthcare organization (a foundation university hospital) using convenience sampling. The data were analyzed using structural equation modeling (SEM). The findings reveal that GHRM has a negative direct relationship with OI, whereas VWGB is positively associated with employees' organizational identification. In addition, the results indicate that GPC mediates the relationships between GHRM, VWGB, and OI, while GP does not demonstrate a significant mediating effect. Overall, the findings highlight the importance of supportive green organizational contexts and voluntary pro‐environmental behaviors in fostering employees' identification with their organizations. These results provide implications for healthcare managers seeking to strengthen organizational identification by fostering supportive green organizational contexts and encouraging voluntary pro‐environmental behaviors, while ensuring that sustainability‐oriented human resource (HR) practices are perceived as supportive rather than controlling.
