This article focuses on the challenges facing organisation among the hardest-to-reach working women in the informal economy. What gives some of them the impetus and courage to organise? What is distinctive about the strategies they draw on to transcend their structurally disadvantaged position within the economy? What barriers do they continue to face in their efforts to address the injustices of the economic system? Through analysing the organisational strategies used in different contexts and for different sets of workers, we can start to see a different battery of weapons among these working women, which serve them better and more transformatively than the weapons of the weak on which they previously relied: the weapons of the organised. This article discusses these issues specifically in relation to the experience of two organisations: MAP Foundation, Thailand, and KKPKP, Pune India.
