Workers will receive a pay increase of 11.6%, and strike action will not go ahead
Union members at Dublin Bus have voted to endorse the pay deal negotiated at the WRC.
Bus drivers with SIPTU voted by 58% to 42% in favour of the proposals, while all other grades approved the deal by majorities of between 70% to 90%.
NBRU members, meanwhile, accepted the deal by 79%.
The deal will see an annual pay increase of 11.6% over the next 15 months.
A series of eight strikes that had been scheduled for this month will now not go ahead.
SIPTU organiser Owen Reidy said: "SIPTU members have been clear that given the sacrifices made by them during the years of economic recession they were due a decent pay increase.
“Having resolved this dispute after negotiations with management, it is evident that further problems will arise in the company as long as the Government and the Minister for Transport, Shane Ross, in particular, fail to substantially increase the subvention for public transport in line with other EU countries," he added.
NBRU General Secretary Dermot O'Leary said: "Despite reservations on some of the issues contained in the proposals, our members have decided, after eight long years of pay stagnation which included pay cuts, to accept the offer on pay proposed by the WRC.
"In doing so our members have once again demonstrated that it is their desire to continue to provide a public bus transport service to the citizens of our Capital City despite the lack of support in by the State in providing sufficient subvention."
In a statement, Transport Minister Shane Ross "[welcomed] the outcome so far but notes that there are further ballots to take place".
