STUDY Trade Unions in Transformation Mega Sporting Events in Brazil: Trade Unions’ Innovative Strategies for the Construction Industry MAURÍCIO ROMBALDI Januar 2018 n The hosting of both the 2014 FIFA World Cup and 2016 Summer Olympics in Brazil forced the country´s trade unions to seek new methods of organisation and coop­eration. Campaigns for decent work, launched by the Building and Wood Workers´ International(BWI), proved to be successful and made the life of thousands of work­ers easier and safer. n Brazilian trade unions have generally operated separately from one another, due to diversity in their historical and political affiliations, and were unaccustomed to conducting joint negotiations. The main challenge – and merit – in implementing the Decent Work Campaign was therefore to unite trade union organisations usually segregated by both geography and sector. n Trade Unions in Transformation is an 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.
