Union representatives have met politicians in Waterford to discuss the threat of job losses and wage cuts at the Bausch and Lomb manufacturing plant.
SIPTU's Alan O’Leary said he wanted TDs and senators to seek more time to discuss the management plans and to push back the 17 June deadline for the conclusion of cost-cutting talks.
Last week the owners of the contact lens manufacturer announced that it would close the company's Irish plant, unless they get union agreement on a plan for a 20% pay-cut for staff, on top of 200 job cuts.
SIPTU says the plans for rationalisation on top of the restructuring of wages are complex matters and the company needs to allow more time to engage with workers.
The union said it would ask TDs to use their influence with the Minister for Jobs and the IDA, to ensure that the plan for job cuts and wage reductions was not rushed through.
The union also wants to know when the Government first became aware that jobs at the company were under threat.
Among those attending the meeting are Paudie Coffey and Maurice Cummins of Fine Gael, David Cullinane of Sinn Féin and Ciara Conway of Labour.
