Trade Union Pluralism, Institutional Coordination and Collective Bargaining: Evidence from Zambia's Public Sector

The liberalisation of trade union registration has expanded freedom of association in many developing countries, yet its implications for collective bargaining and worker representation remain contested. This study investigates the factors driving trade union proliferation in Zambia's public sector and examines their implications for industrial relations. A mixed-methods approach was employed, combining survey data from public sector employees (n=68), with semi-structured interviews involving trade union leaders, employers, and labour administrators (n=18). Quantitative data were analysed using descriptive statistics, while qualitative responses were subjected to thematic analysis to triangulate the findings.
It was found that the liberalisation of union registration following the 1997 Industrial and Labour Relations reforms was perceived as the principal driver of union proliferation. However, leadership disputes, personal ambitions, governance deficits, and dissatisfaction with existing representation also emerged as significant contributory factors. The pre-1997 one-union-one-industry model was perceived as having provided stronger collective bargaining, more coherent worker representation, and more effective dispute resolution than the current pluralist framework. The findings further suggest that union proliferation reflects the interaction of legal reform and organisational governance rather than legislative liberalisation alone.
The study contributes to industrial relations theory by proposing the Contributory Institutional Coordination Framework. The emergent framework identifies institutional coordination as the mechanism through which legal reform shapes the relationship between freedom of association and collective bargaining effectiveness. This presents a departure from the assumption that increased organisational choice necessarily strengthens worker representation. Rather, the findings demonstrate that the effectiveness of union pluralism depends on institutional arrangements capable of coordinating representation. Conclusively, labour law reforms should balance constitutional guarantees of freedom of association with governance mechanisms. This helps to sustain coherent and effective systems of collective bargaining.
