STRIKE action at Dublin Airport is looming once again just days after the threat of industrial action was lifted by SIPTU.The decision to remove that threat at the start of the month was conditional on progress in talks between the union and Aer Lingus and the DAA over a €750 million deficit in airport workers' pension fund. Talks have resumed between the warring sides but those negotiations were said to be in a 'dark place' by SIPTU in recent days. The union has dismissed new offers by both companies to resolve the dispute as 'derisory'. The warring sides dispute the figures but union says the offers are not good enough and have asked the Labour Relations Commission to intervene once more. According to SIPTU Organiser, Dermot O'Loughlin: 'Both committees have concluded the proposals are derisory in the context of the scale of the pension deficit. 'Following a meeting at the Irish Congress of Trade Unions we have written to the Labour Relations Commission (LRC) seeking its assistance to obtain a very significant improvement on the monies offered by both companies. ' The pension committees have also asked the LRC to urgently comment on the status of this negotiation process.'
