Abstract
The study explores the interplay flanked by green HRM practices (GHRMP) and organisational citizenship behaviour (OCB) in banking institutions in Hyderabad, Pakistan, focusing on the mediating impact of organisational commitment. GHRMP are recognised for promoting environmental sustainability and corporate social responsibility. OCB, reflecting discretionary employee behaviour, is pivotal for organisational success. This research aims to ascertain whether organisational commitment mediates the association between GHRMP and OCB in the banking sector of Hyderabad. Data were collected through closed-ended surveys, employing convenience sampling with 200 questionnaires from banks. Smart PLS software facilitated model development and assumption assessment, while SPSS was used for data analysis. Findings reveal that organisational commitment mediates the relationship between GHRMP and OCB in banking institutions. These results underscore the potential of GHRM to enhance organisational commitment, thereby fostering greater OCB participation among employees. This research contributes to academia by elucidating the connections among bank employee commitment, GHRMP, and voluntary employee behaviour. Banks can use these insights to devise and implement GHRM strategies that support environmental responsibility while enhancing staff engagement and organisational citizenship. Integrating sustainability initiatives into HRM processes can cultivate a culture of organisational citizenship and environmental responsibility.
