This article navigates ruptures and transformations in the processes of resistance performed by Iranian workers between two key events of the history of contemporary Iran: the 1979 Revolution and the 2009 Green Movement. It explores how labor activism emerged in the Islamic Republic, and illustrates how it managed to survive. Drawing from the concepts of resistance, collective awareness and counter-conduct as its theoretical basis – between Antonio Gramsci and Michel Foucault – the article details the changing strategies that workers adopted over time and space to cope with the absence of trade unions, monitoring activities, and repression in the workplace. It demonstrates that workers' agency was never fully blocked by the Islamic Republic. However, it tests the limits imposed by the social context to discourage activism, beyond state coercive measures and policies.

This paper explores the transformations of the Islamic Republic of Iran’s dominant narratives on labor between 1979 and 2009. By analyzing official May Day speeches of this period, it navigates multiple constructions of workers’ roles, which were systematically propagated by the IRI’s Supreme Leader and president over time. The analysis relies on the following primary sources: from the 1979 May Day sermon, pronounced by Ruhollah Khomeini, to the 2009 speech given by Mahmoud Ahmadinejad, together with messages sent by Ali Khamenei, Hashemi Rafsanjani and Mohammad Khatami. Showing how workers’ role—understood as a collective and distinct group—was gradually minimized, this paper argues that a bottom-up cleaning up process slowly purified May Day. In fact, the IRI progressively neglected workers as (revolutionary) social actors and interlocutors, as it stopped talking to masses and started speaking to middle classes.
