In 1931, Foa graduated in Law at the University of Turin and worked in a bank. In 1933, he joined Giustizia e Libertà, an anti-fascist political movement. He was arrested by the OVRA in May 1935 and was condemned to 15 years in prison. He shared his cell with Ernesto Rossi, Massimo Mila and Riccardo Bauer.
Foa was released in August 1943. He joined the resistance movement and entered the Partito d’Azione (Action Party, PdA). As a PdA member, he joined the Comitato di Liberazione Nazionale (National Liberation Committee, CLN)
On 2 June 1946, Foa was elected member of the Constituent Assembly and he became a member of the Commission of the Seventy. Foa’s name is linked to articles 39 and 40 of the Constitution dealing with the freedom of trade union organisation.
When the Partito d’Azione dissolved in 1947, Foa joined the Partito Socialista Italiano (Italian Socialist Party, PSI) and was elected an MP in 1953 (and again in 1958 and 1963). In 1957, he joined the left-wing trade union of Giuseppe Di Vittorio, the CGIL, and became an influential and highly charismatic trade union leader.
A leading intellectual of the Italian non-Communist left, Foa supported the theory of the political autonomy of the working class, which would later inspire the foundation of extra-parliamentary leftist groups (PSIUP, PdUP, DP).
At the end of the 1970s, Foa left the trade union and active political life to devote himself to historical research and publishing. He taught Modern History at the Universities of Modena and Turin and researched the history of the working class and of the trade unions. Publications of this period include La Gerusalemme rimandata: Domande di oggi agli inglesi del primo Novecento (1985), a study of English working class movements at the beginning of the twentieth century.
In the late 1980s, Foa played an active part in the re-thinking of the Italian left and took a keen interest in the debates within the Italian Communist Party. In 1987 he was elected Senator from the PCI’s list of candidates.
In 1992, Foa retired, dividing his time between Rome and Formia. One of his last public appearances took place in 2002, when Foa joined the “Manifestazione dei Girotondi”, a spontaneous civil movement that developed in 2002–2003 in several Italian towns.
Defined as "the critical voice of the Italian left", Foa devoted his life to Italian and European politics in their widest sense, and constantly expressed his confidence in the young. From the role of the trade unions, to the place of science in our contemporary society, Foa’s interests embraced crucial aspects of modern life and society.
He died on 20 October 2008 in Formia.
On 21 October 2008, Italian newspapers were filled with tributes to Foa. In La Repubblica, the journalist Miriam Mafai recalled his impatience when asked what the beleaguered Italian left should do. "It’s a waste of time and sense to try to define a leftist identity" – Mafai recalled Foa saying – "You have to do what is right and necessary for the country. It is up to posterity to decide whether it came from the right or the left."
