Abstract
Green human resource management (GHRM) and corporate social responsibility (CSR) have recently gained more attention in the business world. This study aims to investigate the role of corporate support for employee volunteering (CSEV) in strengthening the impact of GHRM on adopting CSR practices of the best 30 firms registered in EGX100 at the Egyptian stock exchange and engaged with CSR activities. Therefore, a conceptual framework was proposed to list theoretical concepts of GHRM, CSEV and CSR to form hypotheses. Data were collected from 326 respondents occupying the highest managerial positions in the studied firms. Using a structural equation model (SEM), the results indicate that both GHRM and CSEV influence positively on adopting CSR activities. Furthermore, CSEV plays a positive moderating role in strengthening the impact of GHRM on adopting CSR in the studied firms. These findings and their managerial implications were discussed in theory and practice.
