In Argentina, a third of workers are in a vulnerable situation, receiving low incomes and not registered in the social security system, thus lacking basic labor rights. Self-employed, entrepreneurs, temporary workers, members of cooperatives are some of the categories that we can find within this universe, which until a few years ago was discredited and often made invisible as a collective. For decades the idea prevailed that this group of workers was transitioning towards registered employment. But this perspective has been losing its validity and since the beginning of the twenty-first century has been gaining ground the notion that there is a Popular Economy, which must be understood in its own terms and not only as a temporary situation or as adjacent to the rest of the economic system. The context of the pandemic strengthened this group of workers who had to create new alternatives to face the crisis and to persist. Also, the State implemented a series of policies to support this sector. The aim of this chapter is to analyse how language has operated to generate the recognition and the legitimacy of certain practices and institutions of this sector of the labour market, which until now have been veiled and discredited.
