Workers over 55 are "a vast untapped talent" with a "huge amount" to contribute to any workforce, the Pensions Minister said.
Announcing measures designed to help older people in the workplace, Steve Webb said:
We are living longer and can expect many more years of healthy life. It's great news - but it's something that as a society and as an economy we need to respond to.
The business case is compelling and the research we are launching today sets out clearly the advantages for individuals, employers and the state.
As part of building a fairer society, I am determined we boost our support for older workers and help employers challenge outdated perceptions to see the real strengths of this important section of the workforce.
