The National Bus and Rail Union has announced it has withdrawn from the talks concerning cost savings at Iarnród Éireann.
In a statement this evening, the General Secretary of the NBRU, Dermot O'Leary, said the company had made no serious attempt to address the concerns of its members.
He said the onus was on management and the Government to address the concerns of all staff at the rail company.
Mr O'Leary said that they had adopted a "divide and conquer" which was being aided by some on the workers side.
He warned that provocation by the company "will inevitably result in a reaction", but that it was up to the members to decide what that reaction would be.
The NBRU had previous rejected, by a three to one majority, proposals by Iarnród Éireann.
While SIPTU had also rejected the plans, several other smaller unions had voted to accept the plans put forward by the Labour Court.
In April, the Court recommended pay cuts for a 28 month period and the establishment of a committee to pursue non-payroll savings.
Earlier, the company had warned that rejection of that Labour Court plan could result in compulsory redundancies and the closure of railway lines.
A SPOKESPERSON for Iarnród Éireann has urged NBRU officials to reconsider their decision. Withdrawing from the process would only put the livelihood of their members at risk, according to a spokesman.
He said Irish Rail would continue to work with other unions involved to seek the savings "necessary to address our financial crisis, protect our services and the security of employment of our workforce."
