Unions say the action is being taken following a dispute concerning the outsourcing of jobs
SIPTU and Unite members will begin a strike of 'indefinite duration' at the Cadbury plant in Coolock, Dublin at 7am tomorrow.
The dispute concerns the outsourcing of jobs.
As part of a restructuring proposal, Cadbury - now owned by the Swiss group Mondelez International - proposed to outsource 17 jobs in its stores division.
A Labour Court recommendation was rejected by the two unions.
John Dunne, SIPTU Sector Organiser, said, “the Labour Court recommendation had previously been rejected by a large majority of the 350 union members employed in the production plant. SIPTU and UNITE members proposed further talks on reducing costs and increasing flexibility in relation to the operation of the store facility at the plant.
"This proposal was rejected outright by management leaving the workers with no option but to take the industrial action that will begin tomorrow morning," he added.
Gerry McCormack, SIPTU Manufacturing Division Organiser, says the attempt to outsource jobs is being seen as a 'further erosion' of the plant's viability, following the movement of the production of Time Out bars to Poland.
