Enhancing employee wellbeing and happiness management in the wine industry: unveiling the role of green human resource management.

Background: In today's business environment, where sustainability has emerged as a strategic axis of business practices, the study of the link between human resources management and environmental management becomes increasingly necessary. In this sense, the present research focuses on analyzing the impact of Green Human Resource Management (GHRM) on the Sustainable Performance (SP) of Spanish wineries, as well as the mediating effect of Employee Wellbeing (EW) and Work Engagement (WE) on this linkage. In addition, age, size and membership in a Protected Designation of Origin (PDO) are introduced as control variables to increase the precision of the cause-effect relationships examined.

Methods: The study proposes a conceptual model based on previous studies, which is tested using structural equations (PLS-SEM) with data collected from 196 Spanish wineries between September 2022 and January 2023.

Results: The findings of the research reveal the existence of a positive and significant relationship between the GHRM development and the SP of Spanish wineries, as well as the partial mediation of EW and WE in this association.

Conclusions: The uniqueness and significance of this study can be attributed to several crucial factors. First, it enhances the understanding and knowledge regarding the advantages associated with GHRM development. Second, no prior research has conducted a comprehensive study on GHRM as a catalyst for SP within the context of Spanish wineries. Third, to the best of the authors' knowledge, no previous study has analyzed the mediating role of EW and WE as mediators in the relationship between GHRM and SP of wineries.
