Former workers at Vita Cortex have entered their second week of their sit-in dispute to secure outstanding redundancy payments.
A SIPTU statement confirmed that a delegation representing health workers in Cork and the greater Munster area met with the protesters today.
SIPTU's National Health Division Organiser Paul Bell, who led the delegation to the plant, said: "The purpose of our visit is to reinforce the Vita Cortex workers and their community, who are committed to fighting a gross injustice which has been perpetrated upon them by an employer who has demonstrated an overt disregard for the loyalty of their employees."
"The union has said that it is committed to mobilise all SIPTU health workers in the Munster area and beyond as part of any SIPTU action proposed nationally, and has assured the local representatives that all health workers within the SIPTU ranks in both public and private healthcare will stand with them in their continued struggle, a struggle which all workers throughout Ireland cannot afford them to lose."
Bell added: "I can say that the workers' morale is high and optimistic having received so much support from workers from all over the country and their local community."
The union called on Minister for Jobs, Enterprise and Innovation Richard Bruton to "break his silence" on the issue and help workers to secure their "rightful entitlements.
A spokesman for Mr Bruton said that the minister's office has been in contact with the union and made them aware that the industrial relations machinery of the State is available to them to help them resolve the dispute.
