Influence of Industrial Relations Management Practices on the Performance of Manufacturing Firms in South-South Nigeria.

Abstract

This study investigated the influence of industrial relations management practices on the performance of manufacturing firms in South-South Nigeria. Specifically, it evaluated the effects of employer-employee relations and labor relations, to achieve the study's objectives, two research questions were raised and two hypotheses were formulated. Relevant literature was reviewed to provide theoretical and empirical grounding. A descriptive survey design was adopted. The study population comprised 385 employees drawn from the selected manufacturing firms in South-South Nigeria. Using the Krejcie and Morgan (1970) sample size determination table, a sample of 191 respondents was selected. Data were collected through a structured questionnaire and analyzed using descriptive and inferential statistics. Research questions were answered using simple percentages and mean scores, while hypotheses were tested using multiple regression analysis via SPSS version 25 at a 0.05 significance level. Findings revealed significant relationships between each dimension of industrial relations management (employer-employee relations and labor relations,) and the performance of manufacturing firms. The study concluded that sound industrial relations management practices foster employee satisfaction, enhance productivity, support policy development, and create a work environment that promotes motivation, morale, and positive attitudes. These practices also ensure fair compensation and improve management’s decision-making capabilities regarding labor and production costs. This study contributes to the existing body of knowledge by empirically establishing the multidimensional impact of industrial relations management practices on firm performance within the manufacturing sector in South-South Nigeria—a region with limited prior focus in industrial relations research.
