Nathan Long, senior pension analyst at Hargreaves Lansdown, said the report's findings were concerning as many people, particularly those retiring in the next decade or two, will not have not saved sufficiently for their retirement and will be forced into working longer.
He said: "Forward-looking employers are already looking to retain the skills acquired by their older members of staff over a lifetime of work, and ensure they are passed on to younger generations.
"An open dialogue around retirement is crucial to break down biases and stigmas attached to retirement and ensure both employers and employees get the most from their working relationship.
"After all, a motivated, diverse workforce that includes older workers is good for businesses."
