Redundancy payments in the Republic are well below the EU average despite the increase introduced last month, according to a new study.
The report found that payment levels in some EU states are five times those in others, and that Irish workers still fare relatively badly.
Statutory redundancy payments more than doubled last month, to two weeks' pay per year of service.
The previous rate had been one week for every year worked from the age of 41, and half a week for every year under that age.
However, statutory payments remain 16 per cent below the EU average, says the study by Mercer Human Resource Consulting.
It compared the minimum statutory paid notice and severance pay across EU states for a white collar employee aged 40 on a salary of €30,000 and made redundant after 10 years.
Prior to last month's increase, an employee in the Republic fitting those criteria would have received € 6,509.
This would now stand at €14,128.
In the EU, however, the average payment for such an employee would be €16,745.
Mr Paul Mercer, European partner with Mercer Human Resource, said the recent increase was welcome even though Irish payments were still lagging behind.
The study found that France, the Netherlands and the UK had the lowest redundancy levels.
The most generous redundancy payments were in Spain, Belgium and Austria.
"Redundancy payments often reflect the labour market culture of the country," said Mr Webb.
"Legislation is light in some member-states to allow for a more flexible and competitive labour market.
"In others, the government takes a more active role to protect employees."
Organisations in the United States are not legally required to provide redundancy pay.
However many organisations give staff two weeks' paid notice, the equivalent of €1,235 based on the white collar employee examined in the study.
Redundancy payments are also low in Japan, said Mr Mercer.
An employee on the equivalent of €30,000 would receive just €2,308 after 10 years' service, according to Mr Mercer.
