Thursday's strike action by Luas drivers will go ahead, after SIPTU and Luas operator Transdev failed to reach an agreement in their long running pay dispute.

Talks between the two sides were adjourned after Transdev and SIPTU failed to agree on on proposed pay increase for drivers.

Transdev had been offering a 13% increase while SIPTU has indicated it was seeking an improvement on the Workplace Relations Commission deal that was rejected last month by drivers, which amounted to 18%. 

Earlier, the three non-driver grades at Luas voted to accept the 13% pay offer from Transdev.

SIPTU's Owen Reidy says it's regrettable that an agreement between the drivers and the company could not be reached:
