The article illustrates the Italian process of work precarisation and the collective resistance of precarious workers. It interprets them in terms of the birth of a collective identity that conducts a critique against precariousness while developing learning resources. Through discursive analysis of the Serpica Naro catwalk, organised in the area of Milan by the activists of the May Day Parade and the San Precario network, the article illustrates the process of construction of this collective identity that uses irony and playfulness to resist and denounce precarious working conditions. The purpose is to interpret the anti-precariousness movement as a process of critical urban learning that creates the viability of spaces for resistance in metropolitan contexts.
