Purpose: The purpose of this research is to investigate green human resource management (GHRM) and its effect on the sustainable competitive edge in the Nigerian manufacturing industry. A case of this study was directly referenced to the employees of Dangote Nigeria Plc. The components of human resource management were coined to fit into the green approach as the study came up with green recruitment, green training and development, green compensation and green employee relations. All these sub-variables were used to measure the predictive outcome such as a sustainable competitive edge in the Nigerian manufacturing industry.
Methodology: A methodology was adopted as the main research paradigm to discover reality. It was quantitative research which collects primary data through an online Survey Monkey from the 242 employees of Dangote Nigeria Plc under four business branches in Lagos State, Nigeria. It was a cross-sectional survey which employed descriptive research for the study. And due to some field constraints in the course of survey exercise, only 217 responses were retrieved which approximate to 89.67% of the total response rate available for analysis. Also, a mini-pilot survey of 30 was conducted to ascertain the validity and reliability of every item in the research instrument.
Results: The study provided empirical evidence to discovered using both descriptive statistics and multiple regression analysis that, green recruitment practices, green training and development practices, green compensation structure and green employee relations, all have a positive and significant effect on the sustainable competitive edge in the Nigerian manufacturing industry. These findings, however, was used to modify the assumptions of an existing theory such as instrumental theory which prioritised shareholders wealth maximization over the process and environmental consideration in the course of business operation and establishment.
Recommendation: The study recommends to the organisations operating in the Nigerian manufacturing industry to embrace the process of business operation while diverting attention to the environment under which the business operates in such a way that would be environmentally friendly and harm-free of pollution to the residence.
