The Role of Green Knowledge Sharing in the Indirect Effects of Green HRM on Employee Green Behaviors Via Green Empowerment: Evidence from Vietnam’s Hospitality and Tourism Sector

This study explores the impact of Green Human Resource Management (GHRM) on Green Organizational Citizenship Behavior (GOCB) and Green In-role Performance (GIRP), focusing on the mediating role of Green Employee Empowerment (GEE) and the moderating role of Green Knowledge Sharing (GKS). Data were collected from 291 employees working in green-oriented organizations in Vietnam, specifically within job roles in Administrative and Office Support and Sales and Marketing sectors in the Hospitality and Tourism industry. Using Smart-PLS 4.0 for data analysis, the results reveal that both GHRM and GEE positively influence GOCB and GIRP. Additionally, GKS positively moderates the relationship between GHRM and GEE, highlighting the role of knowledge sharing in enhancing the effectiveness of GHRM practices. These findings provide context-specific insights for Vietnamese enterprises in Hospitality and Tourism, illustrating how GHRM practices can drive employee engagement in sustainability initiatives. The study underscores that effective GHRM can significantly enhance employee pro-environmental behaviors, contributing to organizational sustainability goals in emerging economy settings.
