NEARLY one in 10 lawyers have bought an illegal DVD.
And bankers are the worst when it comes to paying for a round of drinks, while workers in gyms and leisure centres steal the most loo rolls.
A new poll of almost 4000 workers names and shames different professions for their anti-social office behaviour.
The study found people in the travel industry are most likely to claim credit for a colleague's hard work, dodge whiprounds by saying they don't have cash on them and even steal workmates' food from the office fridge.
The research said six in 10 employees in travel have been victims of colleagues' grubby and sometimes illegal behaviour.
The survey was commissioned by knockoffornot.com, a website set up to combat the nation's Knock-Off Nigels, who engage in anti-social behaviour in the workplace.
While the travel industry was worst overall, more than a quarter of those in the transport industry say colleagues regularly buy knock-off DVDs from traders at work and those in IT or telecom firms are the biggest culprits for illegal film downloads during office hours.
A knockoffornot.com spokesman said: "Ironically, those working in travel are probably most in need of a holiday to get away from all the Knock-Off Nigels."
