After Slovenia introduced measures to reduce pressure on the mid-term sustainability of the pension system, the European Commission is calling for a reform that would guarantee sustainability after 2020. Trade unions are warning that even an announcement of a new reform could trigger a wave of new retirements. Vice-President of the European Commission Valdis Dombrovskis, in charge of the euro and social dialogue, said, as he visited Ljubljana on Friday, that the reform should build on intergenerational solidarity. Given the demographic changes, the issue needs to be addressed, he said. ‘The longer you delay with a solution, the harder it will get,’ he pointed out. The effects of the 2012 pension system reform are positive and a bill creating a demographic fund is expected to be passed soon, the Commission said. But the Commission believes additional reforms will be needed to ensure long-term sustainability of the system.
