People should be allowed to work longer and everyone should have the right to ask for flexible working arrangements, the Government has been urged.
The Equality and Human Rights Commission called for "fundamental changes" to employment policies to open up more work opportunities for older people and tackle the challenges of an ageing workforce.
The group proposed abolishing the so-called "default" retirement age, extend the right to request flexible working, overhaul employer recruitment practices to prevent discrimination and improve training.
State pension age is currently 60 for women and 65 for men, but will rise to 65 for both men and women by 2020.
The commission said research had shown that extending working lives by 18 months would inject £15 billion into the British economy.
A survey by the commission of 1,500 older people showed most believed major changes were needed to attitudes and policies if they were to reach their goals.
One in four men and two thirds of women said they wanted to keep working beyond the state pension age, the survey showed.
The commission said its study revealed that most older Britons did not want to slow down, many wanted job promotions and others wished to work well beyond the state pension age.
Structural barriers and outdated stereotypes were forcing people out of work early, according to the commission.
Most of the 50 to 75-year-olds questioned said flexibility in hours and locations were crucial to keeping them in work longer, with financial necessity the most important reason to continue working.
