Tens of thousands of commuters are facing disruption
Workers at Irish Rail have announced plans for five 24-hour strikes as part of a pay dispute with the company.
It follows a meeting on Friday afternoon.
The trade union group representing all workers at Irish Rail have decided to serve notice on the company for the following series of industrial actions:
The November 14th strike date will clash with the Ireland v Denmark World Cup play-off at Lansdowne Road.
It comes after union members at Irish Rail voted 'overwhelmingly' in favour of industrial action.
SIPTU members voted by 84% in favour of action amid the ongoing pay dispute at the transport company, while NBRU members backed industrial action by 93%.
The ballot counts come only hours after talks broke down at the Workplace Relations Commission (WRC) overnight.
Tens of thousands of commuters are facing disruption.
Management say they offered a 1.75% pay rise, based on new productivity measures.
However, unions rejected the deal, with Irish Rail workers saying they still have not been offered a 'no-strings' attached deal.
Iarnród Éireann said it regrets the decision.
The company has reiterated that talks at the WRC arose from a Labour Court recommendation - which stated that if at the end of the WRC process there were outstanding issues of difference, they should be referred back to the Labour Court for a final recommendation.
Irish Rail says it "remains committed" to this process.
SIPTU TEAC division organiser, Greg Ennis, said: "While the impending industrial action is regrettable and will no doubt affect the travelling public, our members believe they are left with no option but to pursue such a course on foot of the procrastination by management over what is a reasonable pay claim and which is in line with similar pay awards within the CIE group and wider transport sector".
