Compensation Systems, Equity Perception, and Voluntary Turnover Intention: An Empirical Study in the Nigerian Oil and Gas Sector

This research empirically investigates the mediating role of equity perception in the relationship between compensation systems and voluntary turnover intention in the Nigerian oil and gas sector, with data drawn from organisations in Bayelsa and Imo states. The war for talent in Nigeria's petroleum industry creates persistent turnover pressures, particularly for technical specialists, and compensation equity perceptions represent a critical but underexplored mechanism in this dynamic. A quantitative cross-sectional survey was conducted with 200 petroleum engineers, geoscientists, and operations specialists. Structural equation modelling was employed. Compensation system dimensions assessed include base pay competitiveness, variable pay design, benefits package comprehensiveness, pay transparency, and expatriate-local pay differentials. Equity perception was measured across distributive, procedural, and interactional equity dimensions. Findings indicate that pay transparency and variable pay design exert the strongest effects on equity perceptions, which in turn significantly mediate their relationships with turnover intention. Expatriate-local pay differentials emerged as a particularly potent source of inequity perception and turnover intention among experienced local professionals. Procedural equity partially mediated the transparency-turnover relationship, suggesting systemic fairness concerns beyond individual pay outcomes. The study extends equity theory and turnover research into the African petroleum sector context. Recommendations include benchmarking compensation to industry standards, improving pay communication practices, and reviewing differential pay policies.
