The Irish Congress of Trade Unions has called on the Government to restrict employers from being directors for up to five years if they fail to meet their obligations to their employees.
The group was speaking after a meeting with Minister for Jobs Richard Bruton to discuss the closure of Clerys department store.
ICTU General Secretary Patricia King said it was an appalling situation and Clerys workers had been treated outrageously.
She said ICTU had told the minister that current legislation providing that employers must enter into a 30-day consultation period before redundancies should be actually implemented.
Where that process is not followed, the redundancies should be void, she said.
However, she also said company law should be amended so that any employer or someone working on behalf of an employer who failed to comply with the procedures could be removed as directors for at least five years.
The union met Minister for Jobs, Enterprise and Innovation Richard Bruton this morning to discuss the closure of Clerys department store.
She said Mr Bruton told the delegation he was considering what could be done, noting that Minister of State Ged Nash was already preparing a report for Government.
Unions would continue to press for urgent action, she said.
In a statement, Mr Bruton said the meeting with Clerys' workers and union representatives was constructive and reiterated that what happened during the Clerys' liquidation was an appalling treatment of loyal workers.
A creditors meeting will take place in August.
However, the court heard that the liquidators are establishing a creditors committee to investigate a number of matters of concern.
Kieran Wallace and Eamonn Richardson of KPMG were appointed as provisional liquidators when Clerys closed dramatically on 12 June.
Today that appointment was confirmed in the High Court with neither the workers nor the concession holders challenging it.
