Between 1968 and the beginning of the 1980s, CGIL, CISL and UIL united, setting up the "CGIL, CISL, UIL Federation", a federation that coordinated the three unions, while maintaining their independence. It was like having again the unified CGIL but leaving the three members independent from political influences. This federation, even if didn't take full effect among all the affiliated federation, managed to work in a satisfactory way only at the beginning in the early 1970s, especially during the season called Hot Autumn ("Autunno Caldo").
