Those quizzed admitted to staying late or arriving early by up to two hours in a bid to give the impression that they are more dedicated than their colleagues, a daily reported.

But for more than a quarter, it is to do their job more effectively, according to, which carried out the poll.

Those putting in longer hours to impress their bosses often ended up idle - benefiting no one, said a spokesman for officebroker.
