The responses were analysed using the PLS-SEM statistical technique using Smart-PLS software towards testing the proposed model. The research findings found that employee’s understanding of the company’s CSR to be the most significant predictor of employee CSR engagement accompanied by using ethical leadership with the moderating impact of Person-Organisation Fit. It is evident that social exchange values may affect employees towards Corporate Social Responsibility (CSR) engagement. Contribution to ethical leadership and CSR engagement are discussed.
