Demonstrators take part in a march organized by Italy's main labor unions, in Rome's St. John Lateran square, Saturday, Oct. 16, 2021. The march was called a week after protesters, armed with sticks and metal bars, smashed their way into the headquarters of CGIL, a left-leaning union, and trashed its office, during a demonstration to protest a government rule requiring COVID-19 vaccines or negative tests for workers to enter their offices.
