Rome, July 23 - An agreement with Italian unions is a "first step" towards creating new jobs connected with Milan Expo 2015, Labour Minister Enrico Giovannini said Tuesday. The agreement - signed by several unions and Expo Commissioner Giuseppe Sala - covers on-site work at the World's Fair. It includes several "good ideas" on work experience, training, apprenticeship programs and worker safety, said Giovannini. Italian Premier Enrico Letta called it "an excellent deal," one that could become "a national model" for other labor agreements. Measures in the pact that permit greater labour flexibility must still be approved by parliament and passed into law. But Giovannini sounded optimistic that work will be created in the massive project that is already well underway for Expo 2015, which will open on May 1, 2015 and continue until October 31 of that year. "The social partners have understood the importance of the event internationally as a historic opportunity for the country, especially in terms of opportunities for increased employment," said the minister. Some suggest the measures on workplace flexibility could become a model for other sectors and periods.
