West Midland bosses are wasting talented temps on filing and making tea.
Figures released by Birmingham-based recruitment firm Katie Bard reveal just 12 per cent of temporary workers feel their skills are used to the full.
Jobs such as filing, photocopying and making the tea were listed as the worst tasks given to temps.
Yet over half (54 per cent) believe they are as skilled as their permanent colleagues whilst 28 per believe they are better qualified for the job.
Most respondents said they were made to feel welcome by the company and many felt they were treated as part of the permanent team.
However, 41 per cent felt that the most annoying thing about temping was being treated differently.
Verity Stokes, a team leader at Katie Bard, said businesses could get more out of temporary workers if they used their skills to the full.
Ms Stokes said: "We place hundreds of temporary staff in professional offices in Birmingham and across the Midlands and the majority of them are not looking for a stop-gap, but a foot on a career ladder.
"Our figures suggest that companies are using temps more often and that they are seen as a key part of the business - so getting the right one is crucial.
"Once the temporary worker is in place it's absolutely vital that businesses recognise that they can add more to the company than just filing and making the tea.
"It is clear though that many businesses are still not making the most use of their temps."
Of Katie Bard's client companies surveyed, 49 per cent felt temps were of greater or equal value for money than permanent workers.
The main reasons for taking on temporary workers were holiday cover (26 per cent), sick cover (17 per cent), an increase in workload (20 per cent) or project work (22 per cent).
