Examining the mediating mechanism of the environmental organisational citizenship behaviour in the relationship between green human resource management and sustainable performance

Despite the significant role played by green human resource management (GHRM) in promoting sustainable performance (SPerf), there is still a lack of empirical evidence to support this link, especially in developing countries. Therefore, by adopting the ability, motivation and opportunity (AMO) theory, we targeted small and medium-sized enterprises (SMEs) in Jordan that were ISO14001 certified to examine the relationship between GHRM and sustainable performance (SPerf) along with the mediating role of organisational citizenship behaviour towards the environment (OCB-E). By employing the non-probability conditional sampling technique, 97 enterprises were surveyed using a structured questionnaire. The results indicated that GHRM directly accounted for 46.6% of variance in financial performance (FP), 65.5% of variance in social performance (SP) and 37% of variance in environmental performance (EP), and the strongest direct link was noticed between GHRM and SP. The mediation testing results revealed that OCB-E was a partial mediator between GHRM and FP and SP, whereas a full mediation was observed between GHRM and EP. In the following sections, the results, a discussion about the results and the implications have been provided.
