Introduction: Perceived green reward is a significant driver of work engagement to ensure eco-friendly behaviour and optimal performance of employees in the workplace. Purpose: This study investigates the significance of the relationship between perceived green reward and work engagement among employees. Study design/methodology/approach: The study used a cross-sectional survey research design with 140 random participants. The data was analysed using exploratory factor analysis (EFA) and the hypothesis was tested using structural equation modelling (SEM). Findings: The findings of the analysis revealed that perceived green reward has a significant effect on work engagement. Research recommendation: There should be an effective workplace policy on the green reward to promote and engage eco-friendly behaviour among the organisation’s workforce. Originality/value: This research builds on the existing literatures and contributes to the limited study of using the perceived green reward as antecedents of work engagement in Nigeria’s workplace.
