"In order to protect minimum wage and social standards in cross-border regions marked by considerable economic disparities, trade unions have built cooperation structures across adjoining (usually sub-national) regions. Since the 1970s more than 40 Interregional Trade Union Councils (IRTUCs) have been established. This article investigates emerging practices of cross-border trade union cooperation in the West Pannonia region between eastern Austria and western Hungary. It argues that IRTUCs can play an important role in fuelling cooperation to preserve wages and labour rights in cross-border regions, particularly in sectors with high precarious employment. While actual practices are contingent on regional union strategies as well as industrial relations and labour market institutions, cross-border cooperation occupies an important place within European industrial relations practices and can support new forms of capacity-building.
