Unity didn't survive 1985 when a law issued by Bettino Craxi cabinet cut the "sliding wage scale". The PCI called for a referendum to cancel the law. Unofficially the three unions already expressed different views about that law. The different positions became public domain when the parties of Craxi's cabinet, (DC, PSI, PSDI, PRI, PLI) launched a political offensive to defend the law and sank the referendum. The PCI led by Enrico Berlinguer on the other side called all the forces in opposition to the law, included CGIL led by Luciano Lama, to be united in favour of referendum.
