Our inductive study of two transnational labour solidarity efforts focuses on the role of campaign governance. Specifically, we study contrasting campaign strategies, tactics and coalition structures in campaigns by two global union federations, UNI Global Union and the IUF, contextualized in terms of how these campaigns unfolded in India. Our contribution consists of two arguments. The first is that a degree of internal consistency amongst different campaign elements is important for success, and the second is that a mode of articulation that allows for local concerns in affiliate countries to find voice in global campaigns is more likely to result in concrete gains at the local level.
