This academic study of the Argentine sex workers’ union examines their movement and its power despite the seeming impossibility of organizing. The authors, Kate Hardy and Katie Cruz, argue that the secret was effective organizing: building solidarity through emotion, intimacy, care, and connection rather than through traditional union structures that lack these mechanisms. AMMAR, founded in 1995, disrupted practically every assumption about who could organize, how labor movements worked, and redefined what constitutes a “worker”. A majority of these workers were street-based sex workers who faced intense social stigma and were often criminalized. This new model of organizing was focused on radical acts of care as opposed to the dominant unionization based on shared employers. The union walked through city streets providing condoms and food to other women on the streets, as well as threw parties, gave thoughtful gifts, and most importantly, showed up for one another consistently. They dreamt of transforming street environments to one fostering solidarity, inclusivity, and respect. This disruption was not only structural but psychological, as women who had internalized incredibly deep shame and isolation were transformed into political subjects who identified openly and collectively as workers, with 84.9% of surveyed members adopting the identity of “sex worker” over “prostitute,” deliberately rejecting victim politics in favor of labor identity. AMMAR’s advocacy contributed directly to the abolition of the legal codes that allowed police to arrest sex workers without trial (edictos policiales) in Buenos Aires in 1998. The union also secured access to healthcare, even though the public healthcare system was under extreme stress and strain due to economic crises during this time. The unionizing of AMMAR showed proof of the ability to organize and gain collective power across Latin America, even within stigmatized and legally unprotected worker communities. The emphasis here on the human connection of care was the driving force of these movements as opposed to the margins of resistance.
