(ANSA) - Rome, July 25 - Public-sector strikes threatened by Italy's largest labor union CGIL and third-biggest union UIL for September were confirmed on Wednesday. "We have started the procedures and on August 1 we will announce the exact date for the September strike," said CGIL Secretary-General Rossana Dettori. The strike is to oppose the government's hotly contested 26-billion-euro package of spending cuts and sell-offs known as the spending review. The cuts, which among other things aim to avert a 2% increase in VAT scheduled for October, include a 10% reduction of staff and 20% reduction of managers in Italy's large public administration, as well as trimming benefits such as meal vouchers. The measure, which will go before the House at the end of July, was approved by the cabinet earlier this month.
