One in five bar staff are now graduates and experts say it is because university leavers find it increasingly hard to find professional work.
Nineteen per cent of bar workers went to university, compared with 3 per cent 30 years ago, the Chartered Institute of Personnel and Development (CIPD) found.
The research, based on data from 6,000 workers, also found that 17 per cent of waiters are graduates, compared with 2 per cent three decades ago.
