Precarity has been consolidated as a central concept in theoretical and political discussions around labour market(s) and labour relations and conditions. Moreover, it has strongly been linked with specific sociodemographic groups, prominently with youth. Both theory and empirical evidence have suggested that precarity functions as a necessary step towards integration in the labour market, as a kind of indispensable rite of passage to labour adulthood. Nevertheless, despite its resonance, precarity remains a fuzzy buzzword that needs to be further problematized and evidenced. Focusing on a specific case study, that of Greece, we try to unfold a two-fold approach: to define and measure precarious forms of labour at the level/scale of the labour market as a whole and to detect and disentangle the role of age in specific sectors of economic activity where precarious labour is more prominent than in others.
