L’articolo comparirà sull’e-book, La tutela previdenziale per i lavoratori autonomi, a cura di G. CANAVESI e V. FILÌ, nella collana Temi di Sicurezza Sociale, Editoriale Scientifica di prossima pubblicazione.

The paper analyses - from the perspective of the main issues raised by social security pluralism – the free techniques for recomposing the contributory seniority of self-employed workers registered with the INPS. In particular, the paper analyses the main interpretative questions posed by the simultaneous existence of different and alternative cumulation models. In particular are examined the relations between the discipline of the “cumulo” introduced by the l. n. 228 of 2016 and the concurrent cases provided for by the discipline of the “totalization” and the never abrogated legislation of 1966.
