Student jobs could have a negative impact on future graduate careers.

The University and College Union (UCU) claims students who work can miss out on extra curricular activities that appeal to employers.

The university lecturers representative body is concerned many students could be lacking vital social experiences as their non-working friends are able to join clubs and societies, boosting their CV.

Heading a union society, working on a student publication and being part of a sports team are activities which might have a positive impact on employers when hiring graduates.

However, many do not have the chance to get involved.

The UCU claims half of all students who do a full-time degree, work to help pay their way. On average they work 14 hours a week, but some work more than 20 hours a week which is likely to infringe on their time to get involved in university activities.

Sally Hunt, of the UCU, said: "A student who's had to work to live will not necessarily have had the choices to build their career and it means they're at a detriment immediately when they go into the job market."
