Greece\'s largest labor union on Monday warned that the country\'s unemployment will reach 29% in 2013 if the government carries out more planned austerity measures, expected to exceed 11.5 billion euros for 2012-13, as Kathimerini reports. \"The course of the Greek economy is one of decline. In 2012, we are expecting a drop in gross domestic product of 7%. This will create unemployment of 24% level -- 1.2 million people,\" Savvas Rombolis, head of research at the GSEE labor union said. \"Our estimate is that in 2013, unemployment will be between 28 and 29% -- more than 1.4 million people. That\'s because we expect the economy to remain in decline.\" The predictions are to be included in a report that will be published on Thursday. Unemployment in May reached 23.1%, with the under-25 jobless rate hitting 54.9%. The report, Rombolis said, also found that Greeks on minimum wage have seen their spending power reduced to 1979 levels, while those earning an average salary have been pushed back to the equivalent of the early 1980s -- after analyzing wage trends, the price of goods and services, and the impact of successive tax hikes since Greeces major financial crisis began in late 2009.
