Up to a quarter of the workforce at the Coca-Cola operation in Drogheda, Co Louth, face losing their jobs after the company said it was looking at outsourcing some of its services.
It is understood that up to 50 of the 200-strong workforce at Southgate could be affected.
Around 100 of the employees for the soft drinks company work in its integrated services division where the outsourcing may take place. The news was given to staff yesterday.
An informed source said that the losses may reach 40 to 50 staff members but are not expected to go higher than that.
In a statement, the company said it was "changing the way we work to increase our speed and agility".
"The company's integrated services organisation provides a broad range of support services globally, including for finance, procurement, human resources and a number of other areas," it said. "As we move to provide the next generation of services, we're looking for opportunities to think innovatively. This includes using third-party providers to provide managed services."
Coca-Cola has a number of operations in Ireland and makes concentrate at its plant in Ballina, Co Mayo. The only positions that could be at risk are currently based in Drogheda and there was speculation that some of the work could be transferred to India.
Local Fine Gael TD Fergus O'Dowd said any job losses were hugely disappointing.
"Drogheda has been a very important base for Coca-Cola and hopefully it will continue to be," he said.
He is asking the Government to make every effort possible to ensure job losses are "minimised" and 'to attract new industry into Drogheda.
Louth Fianna Fáil TD Declan Breathnach said: "Coca-Cola has been good to Drogheda and the region, but we need greater clarity now."
