STUDY Trade Unions in Transformation Institutionalizing Labour’s Voice in ASEAN: The ASETUC Initiative MELISA R. SERRANO October 2017 n This paper analyzes how the ASEAN Services Employees Trade Union Council (ASETUC) was successful in»institutionalizing« labour’s voice in the integration pro­cess in the pursuit of a more social Association of South East Asian Nations(ASEAN). It demonstrates how trade unions can play a role in shaping political, economic and social landscapes and in linking their organizations and actions at the national, re­gional and global level. n Among the crucial success factors were the common sense of purpose among sev­eral unions, their democratic interaction and bridging the different spatial levels, the flexibility to adopt strategies that resonated with the»ASEAN way« as well as a long-term perspective to their engagement. ASETUC demonstrates how unions can successfully use and develop multiple power resources. n Trade Unions in Transformation is an FES project that identifies unions’ power re­sources and capabilities that contribute to successful trade union action.
