Purpose The paper aims to examine the association of green human resource management (GHRM) with organisational sustainability (OS) through the mediating function of corporate social responsibility (CSR) and organisational citizenship behaviour for the environment (OCBE) in Palestinian health-care organisations. Design/methodology/approach The paper applied a quantitative method in which data are collected from a survey with 88 human resources and quality managers who work in Palestinian health-care organisations. Furthermore, the structural equation modelling method of partial least squares was used for the data analysis. Findings The results demonstrated that GHRM practices positively influenced CSR and OCBE, which eventually influenced OS. Notably, this study offers empirical insights into how to improve OS through CSR, OCBE and GHRM approaches. Originality/value This paper presents the implications for achieving the health care sector’s long-term sustainability by linking strategic environmental goals of human resources management practices with practices of social responsibility and organisational citizenship behaviour, which ensures employee participation in formulating policies and strategies for the organization.
