SIPTU representatives have agreed to suspend work-to-rule industrial action that has led to bus cancellations and delays on Dublin Bus services all this week.
The dispute centres on engineering operatives who perform tasks, including maintenance, refueling and cleaning to ensure buses are ready each morning.
They are seeking pay parity with their traffic operative colleagues, who are on a higher grade.
SIPTU said the period of the suspension is seven days.
Both sides will meet again next week in a bid to fully resolve the dispute over pay and productivity.
Following talks, Dublin Bus said in a statement that the suspension of the work-to-rule was a positive development.
"Dublin Bus welcomes the decision by SIPTU representatives to suspend the work-to-rule industrial action immediately. This is a positive and welcome step towards resolving the current dispute."

SIPTU Transport Sector Organiser John Murphy said: "I think both sides recognised that we weren't going to resolve this in the current situation we were in with the industrial action and the impact that it was having on the services.
"So, in fairness to our reps, committee and management, they did agree that intensive discussions needed to take place and to allow that, we've suspended the action for seven days."
Mr Murphy said the suspension would give both sides space to engage and explore possible solutions.
"We're hopeful we're going into that in the right frame of mind.
He said the company realises some level of pay increase is needed.
"It's the level of increase that we have to negotiate and whether some of our reps might have been unhappy. You know, in fairness, they have to go back to their members in the garage and explain this, so I can understand the position they were in."
Mr Murphy acknowledged the "severe impact" the work to rule had.
At Donnybrook, the largest garage, with over 300 buses, he said there had been 80 or 100 buses that were not fully serviced overnight.
"So by the time they get serviced throughout the day, it is going to have a knock-on effect."
Both sides have agreed to meet again next Monday and Tuesday, where it is hoped there will be a discussion that could be acceptable to be voted on.
Full services will now operate as normal with immediate effect.
Dublin Bus again apologised to its customer for the disruption caused.
Today was the fourth day commuters had been affected by the action after it began on Sunday.
Dublin Bus apologised for any delays caused to customers while Transport for Ireland said the disruption is primarily an early morning issue.
The most affected routes were the 7,14, 15 alongside the E1 and E11 services, which operate from the Donnybrook garage.
The 9, 122, 39 and C1 routes beginning in Phibsborough were also impacted as well as the 120, 123, 15B and the 41 services from Summerhill.
The Labour Court has not recommended what would be a 14.5% pay increase without any concessions on productivity.
But it has called on the parties involved to finalise an agreement on a productivity-based pay increase of 4.5%.
