(ANSA) - Naples, April 19 - Thousands of immigrant workers in the southern city of Naples demonstrated on Friday, asking for guaranteed unemployment benefits for job seekers and people who have lost their jobs. According to police estimates, approximately 2,000 foreigners living in Italy marched through the city center carrying banners and chanting "right to benefits and happiness". Protest organizers placed the number of employed and unemployed laborers taking part in the march as much higher at 10,000. "This is the first time that demonstrators are calling to be allowed access to a citizen's wage, not just legalized work permits," organizers said. Marchers included workers from the nearby Pomigliano Fiat plant and the Campania regional environmental protection agency ARPAC, responsible for waste disposal. Comedian Beppe Grillo's anti-establishment 5-Star Movement (M5S), which gained a huge protest vote in the inconclusive February general election, has called for the introduction of a universal system of unemployment benefits. Grillo's Internet-based movement holds the balance of power in parliament.
