SIPTU and the National Bus and Rail Union have both agreed to attend talks at the Labour Relations Commission next Monday in an attempt to avert a strike at Iarnód Éireann.
Members of the two unions are currently finalising plans to hold a three-hour strike on Friday 23 October, in a dispute over payment for productivity.
A second similar strike is also due to take place in November.
General Secretary of the NBRU Dermot O’Leary said the LRC had asked that the union re-engage at the Commission on the basis that all parties, inclusive of the company, are prepared to discuss all aspects of productivity and that the union agreed with Minister for Transport Paschal Donohoe that the LRC was where these matters should be resolved.
SIPTU Organiser Paul Cullen said his union would also be attending the talks.
The talks are due to begin at 12pm on Monday.
