The Relationship between Green Human Resource Functions and Organizational Citizenship Behavior for the Environment in the Banking Sector in Sri Lanka

— Considering the present context, environmental preservation and conservation are trending and influencing topics. It helps to create win-win solutions for both the organizational level and the environmental level. Going green is a trend in almost all fields in the world, and the human resource management field is no exception. This study aims to analyze the relationship between green human resource (GHR) functions and organizational citizenship behavior for the environment (OCBE). Regardless of the salience of HR functions in translating organizational strategy into employee behaviors, the role of green HR functions in shaping employee green behavior has been under-explored. This research anticipates soliciting further investigations into the mechanisms underlying the nexus between green HR functions and employee green behavior. A discussion on the implications for the banking sector is presented. In this study, the researcher conducted an online questionnaire survey among a sample of 200 executive-level employees in the banking sector in Sri Lanka. The questionnaires are distributed among managerial, executive, and clerical-grade employees based on a five-point Likert scale, and the response rate was 97%. Finally, the collected data was evaluated using the Statistical Package for Social Sciences (SPSS 24.0) using statistical techniques such as mean, mode, variance, standard deviation, correlation, and regression analysis. Moreover, the findings of the research revealed that there is a positive and significant relationship between green HR functions and OCBE. Based on the findings, the researcher is recommended to develop Green HR functions to achieve environmental sustainability. Finally, the findings of this research demonstrated that there is a strong positive relationship between green HR functions and OCBE, and there is a significant positive mediation relationship between fulfilling and collective green crafting. The findings of this study are useful in further enlarging and enriching applications of these concepts in practice.
