Young people are also being held back by ageism in the workplace, according to a new report.

The Employers Forum on Age and careers consultancy Sanders and Sidney have released findings from a survey of 18 to 30-year-olds in four major cities across the UK.

Almost half the respondents said they have been held back at work because of their age.

One in four of those questioned said, despite being qualified, they are considered too young for certain jobs.

A similar number said they would have to leave their current employers to gain promotion.

Ruth Jarratt, spokesperson for the EFA, said: "These findings are a clear message that young workers are still being hampered by ageist attitudes.

"We believe the Government should be doing more to combat age prejudice in the workplace."

Sally Davis, a director for Sanders and Sidney, said: "We have long campaigned on behalf of older workers who are too often marginalised because of their age.

"Clearly there is a job to be done for the young as well."

The survey also showed a difference in opinion among respondents depending on the size of the organisation the employee worked for.

Workers for small firms consistently reported being less satisfied with their career path, training and promotion prospects.
