Dublin Bus has apologised for any delays that may have been experienced by customers due to a work-to-rule industrial action being taken by engineering operatives.
Last night around 190 operatives began the action in a dispute over pay.
Engineering operatives perform various maintenance and general tasks to ensure buses are available to deliver public transport services.
Their union SIPTU has accused Dublin Bus of refusing to meet their claim for pay parity with their traffic operative colleagues, who are on a higher grade.
SIPTU said that an agreed independent external review of the roles supported the pay parity claim.
However, in November the Labour Court said it could not recommend what would, in effect, be a 14.5% pay increase without any concession of productivity or related measures.
The court did recommend that the parties engage to finalise agreement on a productivity-based pay increase of 4.5%.
"Dublin Bus has arranged a meeting with the trade unions for Thursday 6 March, and has asked the trade unions to suspend their industrial action and engage in meaningful negotiations to bring an end to this dispute," a Dublin Bus spokesperson said.
