An agreement has been reached in talks aimed at saving jobs at aircraft engine maintenance firm Lufthansa Technik Airmotive.
After 11 hours of talks, both sides have agreed on a clarification document which they say will help to implement new working arrangements smoothly.
Tonight Lufthansa Technik Airmotive said the threat of protective notice had been lifted and that both sides would work on the detail of the clarification of the agreement.
The company confirmed that jobs at the plant were safe.
There had been fears for over 400 jobs at the plant after the company's owners warned it would put workers on protective notice if staff did not implement agreed working arrangements.
Speaking on RTÉ's Morning Ireland, Willie Quigley of the trade union Unite said some employees were being asked to work overtime, while others in the same section were on reduced hours.
Earlier this year, workers voted to accept proposals to secure a €28.5m investment in the plant.
However, managers claimed that employees are failing to honour the agreement and that some staff are refusing to do overtime, which has led to work being turned away.
Tánaiste and Minister for Enterprise, Trade and Employment Mary Coughlan had expressed concern about the situation and urged the workers to seriously consider their actions.
On her political future, Ms Coughlan said she wanted to stay on as a minister and Taoiseach Brian Cowen had said nothing about her position as Tánaiste.
She said the question of demotion had not arisen, and that Mr Cowen had not indicated plans for a reshuffle. Her priority is to attract investment, she added.
