After recalling the latest events regarding the role of labour unions in Italy –  precisely the FIAT national labour agreements signed from the years 2010 to 2012 as well as the provisions of the article 8 of the Italian Law n. 148/2011 which states that if a labour agreement signed at a local level is approved by the majority of the concerned employees, it shall have validity for all (erga omnes) - the author discusses whether the above mentioned article 8 complies with the Italian Constitution and poses the question about the possibility of implementing article 39 of the Italian Constitution - after 65 years still yet to be enforced – which states that labour unions recognized by the law shall have the power to stipulate labour agreements that have validity for all (erga omnes).
