The Italian labor law is characterized by wide variety，complexity and frequent legislations，and this article aims to comb and analyze the progress of its emergence and reforms. Since the end of the second World War，the Italian labor law system has gradually expanded and matured，and social legislation has played an increasingly important role. Being involved into the European sovereign debt crisis in 2011 forced the Italian government to start several rounds of labor law reforms，covering various areas such as labor contracts and their rights and obligations，labor standards，social security and welfare benefits. Facing the opportunities and challenges brought by the digital economy，the Italian government mobilized the flexibility of the labor market with an active and open policy，and formed an atypical labor type and related labor protection system represented by collaborative labor. Since the outbreak of COVID-19，the Italian government has issued a series of policies and decrees to restore and stabilize the labor market and alleviate social conflicts. The National Recovery and Resilience Plan released in 2021 further maps out the direction of labor policy in the coming years.
