NBRU members at Dublin Bus have voted for industrial action by a margin of over 96%, the union stated today.
Bus stoppages are expected by the end of the month, unless a resolution can be found.
Drivers at the company are seeking pay parity with Luas drivers.
"The result of today’s ballot for industrial action has brought the level of anger among Dublin Bus workers into sharp focus, it is important that the Company and its paymasters would reflect on this result and realise that the level of pay required to resolve this dispute is very much in their gift, to ignore such a resounding message from workers who have had to endure two cost-cutting plans, inclusive of pay cuts coupled to eight years without a pay rise would do a disservice to both workers and passengers alike," said general secretary Dermot O'Leary.
"The National Executive Council of the NBRU will meet on Tuesday 9th August to discuss the range of options around the type of industrial action which may be required to advance bus workers claim for a significant and long overdue pay rise.
"It is also intended that we will meet with colleagues across all five of the trade unions who are party to this dispute, with a view to devising a coordinated approach around industrial action, such a sequence of action can of course be prevented if Dublin Bus indicate that they are willing to come back to the table and discuss the possibility of making an improved pay offer to its hardworking staff."
