Age Action Ireland has urged the Oireachtas to bring forward legislation to abolish the mandatory retirement clauses that require workers to retire at age 65.
Speaking on RTÉ's Morning Ireland, Head of Advocacy at Age Action Justin Moran described the legal requirement as "ageist and mandatory discrimination".
He said a bill to abolish mandatory retirement drew all-party support in the Oireachtas last year but has been stalled since the General Election.
Many workers forced out at age 65 have no option but to claim unemployment benefit until the State pension is given to them when they reach 66, he said.
Mr Moran said people should have a choice, allowing those who wish to retire to do so.
However, he said many people were realising they would not be as financially comfortable as they thought they would be and would like to work for longer.
The social aspect of work was also a big issue for many people in their 60s, he added.
