Slovenia's seven largest trade unions Saturday staged a demonstration in the capital Ljubljana demanding higher wages and opposing the government's plans to reform the pension system. Some 30,000 workers, according to the organisers, gathered in central Ljubljana for the protest with the slogan 'For human dignity'. Police in the capital did not give any estimates on the number of demonstrators. The unions, headed by the country's largest Slovenian Free Trade Union Confederation (ZSSS), called the demonstration to demand from employers a minimum monthly net salary of 600 euros (895 dollars). According to the unions' estimates, some 150,000 workers receive the current minimum net wage of 459 euros. The basic monthly cost of living in Slovenia is estimated at 562 euros per person. The unions also oppose the centre-left government's announced reform of the pension system, in particular the raising of full retirement age from 63 to 65 years. Prime Minister Borut Pahor warned last week the union demands were excessive and could hamper the country's economy. It could also further increase unemployment which has already jumped by three percent to 9.4 percent in the last 12 months due to the financial crisis. The European Commission has urged Slovenia to reform the pension system in order to be able to cope with the cost of its ageing population. Bk/boc
