Within Argentina and beyond, the characteristics of work are changing as work becomes increasingly informal and precarious. Drawing on interviews conducted with informal workers in Buenos Aires in 2002, this article analyzes the ways that the informalization of work during the economic crisis in Argentina shaped the interplay between normative and practiced manifestations of gender, including masculinity and femininity. I argue that although normative understandings of gender in Argentina remain largely uncomplicated by economic restructuring and crisis, the activity of informal work interacts very differently with the performances of these norms, depending on the class and sex of the worker. In particular, I demonstrate that among workers in the popular classes, the characteristics of informal work serve to mediate tensions resulting from women's engagement in paid work, while constituting an obstacle to men's performance of the hegemonic masculinity of the provider. Among middle-class workers, however, engaging in informal work does not result in the same types of tensions between gender norms and performances. I conclude by questioning the long-term nature of changes in gender relations resulting from this crisis and stressing the importance of intersectionality on understanding impacts of economic change. In addressing the question of how an increased dependence on informal work has affected gender relations in Argentina, this article seeks to contribute to wider discussions regarding the malleability of gender systems and the need to understand the effects of global restructuring on local gender relations, including performances of masculinity.
