STUDY Trade Unions in Transformation Towards A Powerful Value Chains Trade Union: South African NUMSA’s Expanded Scope CHERE MONAISA August 2017 n NUMSA's answer to the challenges of globalizing capital is the new strategy of build­ing a value chain union, not centred on its stronghold in the automotive industry, but designed to organize sectors in which NUMSA can gain the most leverage in the economy. n The ensuing expulsion from the national union federation COSATU initially fostered NUMSA's associational power. To ensure its sustainability across its multi-sectoral organizing domain, NUMSA needs to translate it into workplace bargaining power and institutional power. n Trade Unions in Transformation is a FES project that identifies unions’ power re­sources and capabilities that contribute to successful trade union action. This study features among two dozen case studies from around the world demonstrating how unions have transformed to get stronger.
