Many pharmaceutical firms in Nigeria struggle to manage labour costs in a way that supports profitability. Studies indicate that in some cases, labour expenditures can consume a large portion of company resources without delivering proportional financial returns. High wages, extensive benefits, and inadequate workforce planning can increase operating expenses and reduce net profits, particularly when human capital efficiency is low. Thus, this study examined the nexus between labour costs and net profit in listed pharmaceutical firms in Nigeria. An ex-post facto research design was adopted, focusing on a population of seven listed pharmaceutical firms in Nigeria, with a final sample of four firms selected based on the availability of complete financial data from 2015 to 2024. Secondary data were collected from the firms’ audited annual reports, and the hypotheses were tested using a random effects regression model following the Hausman specification test. The findings revealed that labour costs have a significant positive effect on net profit, indicating that proper management of employee-related expenses can enhance financial performance. The study concluded that strategic investment in human capital is essential for sustaining profitability in Nigerian listed pharmaceutical firms. Hence, the Boards of these pharmaceutical firms should strategically allocate resources toward employee compensation, training, and welfare programs. By investing in the skills, motivation, and well-being of staff, firms can enhance productivity, improve operational efficiency, and support research and development efforts, which in turn strengthens net profitability.
