To merge or not to merge? The impact of union merger decisions on workers' representation in Germany

Abstract

AbstractUnion mergers have been widely studied in a variety of countries; however, little is known about their impact on union effectiveness. This article draws on in‐depth interviews with officials and works councillors from four German unions, as well as on a representative survey of German works councils, to analyse how a union's merger status shapes its effectiveness in three spheres of activity: political lobbying, collective bargaining and establishment‐level interest representation. We compare two cases of merger with two cases of continued organisational independence, finding that merger outcomes for individual unions vary considerably across our three union functions.
