Ageism is the most common form of perceived discrimination in the workplace, according to new research.

But almost three quarters (73 per cent) of British workers said they have never felt discriminated against at work with their current employer

The survey by payroll and HR firm ADP found eight per cent of respondents say they have been discriminated against on the grounds of their age

People aged 18-24 are the most likely to feel affected (19 per cent), followed by 25-34 (10 per cent) and those over 45 (six per cent).

Gender (seven per cent) and appearance (six per cent) are the next most reported forms on a list which includes race, religion and disability, as well as education, background, mental health, family circumstances and neurological differences.

ADP managing director Jeff Phipps said: "Workplace discrimination has been making headlines in recent years, whether it is ageism, religion, disability or racial discrimination.

"Yet, as shown in the research findings, most employees find it hard to raise claims or are unaware of what to do.

"Employers must stay alert to this issue, take a proactive approach to tackle potential prejudice and unconscious bias and ensure equal treatment for all.

"A lack of adequate protocol or process in some organisations could undermine efforts to increase inclusivity and create a culture of openness."
