Drivers at Dublin Bus have voted to accept a proposed pay and productivity agreement worth 15.5% over five years.
The deal, which was recommended by the Labour Court, contains cost of living increases worth 11% and a further 4.5% linked to productivity.
The agreement is backdated to 2019.
Members of SIPTU and the National Bus and Rail Union voted to accept the deal by a narrow margin - 50.6% in favour, 49.4% against.
In a statement, Dublin Bus said it was pleased to note the result of the Trade Unions Group ballot on the Labour Court recommendation on the proposed Drivers Pay Agreement.
"The board of Dublin Bus will now consider the Labour Court recommendation," the company said.
Last month, unions at Iarnród Éireann voted to accept a pay and productivity deal worth 10.5% over five years with the potential for a further 4.5% self-funded increase, subject to achieving verifiable efficiencies.
