During its first and last congress in Naples from 29 January to 5 February 1950, the FIL arrived to fix the merge with LCIGL the Americans were hoping for. The decision was immediately disputed both in the legitimacy (because decision was took from FLI executives without any votation) and in the topic (many wanted the FIL to be independent). The PRI had, already in the summer of 1949, invited republican members of FLI to contrast every proposal of merging in other union centre. In the same period the PSU just born, approved an agenda turned toward the creation of a new independent trade union centre. For this reason Italo Viglianesi, autonomist socialist, set up the Gruppi d'azione sindacale unitaria or GASU.
