The holiday period that has just ended, which marked a record increase in the number of COVID-19 infections, was characterized by the adoption of emergency measures of significant impact on daily life and business activities. Law Decree no. 221 of December 24, 2021 (“LD 221/2021”) has further extended the state of emergency until March 31, 2022. Such an extension has entailed, for private employers, among others, the extension of certain emergency measures, including the possibility of implementing the Smart Working using the well-known simplified procedure, as well as the extension of the use of COVID green certification (so-called Green Pass) in the workplace.
