This study critically examines the effect of outsourcing on workforce development in Nigeria using a content analysis approach. The research is framed within systems theory, which views Nigeria's workforce development as a complex system influenced by various interconnected components, including outsourcing, economic conditions, education and training, government policies, labor market dynamics, and organizational strategies. The empirical review explores the effects of outsourcing on organizational performance, employee commitment, and competitive advantage in Nigeria. Key findings indicate that outsourcing can lead to cost savings, improved efficiency, and access to specialized expertise, contributing positively to organizational performance. However, significant negative impacts are also identified, including underpayment, job insecurity, violation of workers' rights, diminished employee commitment, and adverse effects on the local economy. Despite the potential benefits of outsourcing, such as cost reduction and technological advancements, the study underscores the need to balance these benefits against the negative impacts on workers. Recommendations include enforcing labor laws to ensure fair compensation, providing equal treatment for core and contract staff, empowering outsourced workers through unionization, enhancing anti-discrimination protections, fostering emotional attachment and commitment among workers, and promoting local job creation to mitigate the adverse effects of outsourcing on the local economy.
