Starting on Bourdieu's approach to precariousness, this article analyzes this phenomenon as a new flexible norm that displaces the Fordist social norm. The authors argue, based on Gramsci's study of Fordism, that precarization creates a mechanism of discipline for the legitimization of the loss of both labour and social rights, destroying the Keynesian social pact. Such disciplining happens coercively, both by the use of new technologies and by the generalization of the function of Marx's industrial reserve army to all productive strata; and also, by consensus, through a transformation in the work culture, leading to a "new flexible man" with a flagrant loss of its autonomy.
