Manpower Development Programmes and Employee Productivity in Selected Oil and Gas Firms in Bayelsa State

This study examined the effect of manpower development programmes on employee productivity in selected oil and gas firms in Bayelsa State, Nigeria. Manpower development remains a critical organisational strategy for enhancing efficiency, innovation, and competitiveness, particularly in technically demanding sectors such as oil and gas. Anchored on Human Capital Theory, the study adopted a mixed-method research design, integrating quantitative and qualitative approaches. The population comprised 3,000 employees from SPDC, Conoil Producing Limited, and SEEPCO, from which a sample size of 400 was determined using Taro Yamane’s formula. Data were collected through structured questionnaires and semi-structured interviews, with 366 valid responses retrieved, representing a 91.5% response rate. Quantitative data were analysed using descriptive statistics and Pearson’s correlation coefficient, while qualitative data were analysed thematically. Findings revealed that manpower development programmes—particularly training, skill acquisition, workshops, and seminars—significantly enhanced employee job performance and productivity. Mean scores across all productivity indicators ranged from 3.33 to 3.40, indicating strong agreement among respondents. The correlation analysis revealed a very strong positive relationship between manpower development and employee productivity (r = 0.918, p < 0.01), leading to the rejection of the null hypothesis. Interview findings further confirmed that manpower development reduced operational errors, improved efficiency, enhanced safety compliance, and strengthened employee confidence and adaptability. The study concludes that manpower development is a critical driver of productivity in oil and gas firms in Bayelsa State and recommends sustained investment in continuous, job-relevant training programmes aligned with technological and organisational needs. The study concluded that manpower development programmes are a critical determinant of employee productivity in the oil and gas sector in Bayelsa State. The convergence of quantitative and qualitative findings demonstrates that employees who are exposed to continuous training and skill development perform better, adapt more easily to operational challenges, and contribute more effectively to organisational goals. Based on these findings, the study recommends that oil and gas firms should increase and sustain investment in continuous manpower development programmes to further enhance employee productivity.
