Vita Cortex workers in Cork have said they are willing to sit down with company owners if they come to the table with serious intent.
It follows a call by the Jobs Minister Richard Bruton that both sides use the State's industrial relations machinery to resolve the ongoing dispute.
Up to 30 workers are now in week three of a sit-in demonstration for redundancy payments which the company claims it cannot afford.
SIPTU representative Anne Egar said that the company needs to be open about the accounts if the dispute is to be resolved.
Ms Egar said: "Siptu has always used the State's industrial machinery for the resolution of disputes"
"But the position is that the company would have to come to the table with serious intent, otherwise it is just frustrating people and frustrating the use of the industrial relations machinery."
