London: Office flings have become quite a normal story since people spend most of their time at their work place.

A new survey of more than 1,000 workers has found that one in two workers have an affair with a colleague at the office. And the most popular methods of getting promotion these days include having sex with the boss, blackmail and sabotaging other people's work.

One-fifth of them acknowledged sleeping with the boss just to get a promotion. It also showed that many employees are prepared to cheat, lie and stab work-mates in the back to get on in their jobs.

Researchers found that one in five people regularly claim credit for work done by a colleague. A staggering one in three had attempted to get a work-mate sacked while two-thirds admitted to flirting to get their own way, according to a report in 'The Sun'.

Seven in 10 said they were willing to cover up for a colleague's extra-marital activities by lying to that person's partner. But, despite their own faults, four in five were worried about the ethics of their company.

The survey was ordered by Paramount Home Entertainment to coincide with the video release of Changing Lanes, which stars Ben Affleck as a worker who marries his boss's daughter to get on.
