IRISH Rail chiefs are set to meet unions in the Labour Court to discuss plans aimed at saving the company €30m over the next three years.
Unions at CIE have already rejected proposals that included pay cuts of between 2pc and 5.75pc, along with reductions in overtime, annual leave and sick leave.
The company, which lost €20m last year, has said that two-thirds of its costs come from payroll.
Five unions – SIPTU, NBRU, TEEU, TSSA and Unite – say that they have already participated in cost-saving measures worth €100m since 2008.
Management and the unions will meet in the Labour Court on August 30.
The dispute comes as workers at Dublin Bus look set to resume strike action after rejecting a Labour Court deal aimed at saving €11.7m.
Drivers were balloted on the deal, which was struck following overnight talks that brought a halt to a three-day strike earlier this month.
More than 400,000 commuters were left without transport over the August bank holiday weekend.
Some 2,300 Dublin Bus drivers voted on the measures, which proposed that senior management be hit with average pay cuts of up to €3,200 a year, fewer holidays and a longer working week
SIPTU said that 72pc of its members rejected the new proposal, while the NBRU voted by two to one against them.
NBRU assistant general secretary Dermot O'Leary said they needed time to reflect on the overwhelming rejection.
"We would hope that the company would not rush towards a knee-jerk reaction."
Willie Noone, from SIPTU, said it was clear Dublin Bus drivers were unwilling to accept the cost-cutting measures.
"Our members indicated that they were frustrated that yet again they were being asked to provide a public transport service while the subvention to pay for it was continuing to be reduced and there was no end in sight to cuts to their conditions of employment," he added.
Changes to overtime and other allowances were also included in the revised deal.
Neither unions representing the drivers advised them how to vote, but they both insisted the revised proposals offered clarity to workers.
