Millions of British workers are being stressed out by the infuriating behaviour of their work colleagues, according to a study by the Britannia building society.

The research found that the stress list included using other people's possessions, pulling a sickie, talking loudly and leaving desks in a mess.

It also found that three out of five accused colleagues of claiming the credit for work someone else had done.

The study suggested that employees spent five minutes a day moaning about colleagues' "anti-social behaviour" in the office.

Tim Franklin of Britannia says: "It's concerning to see that so many of us are affected by the unfair behaviour of people at work. Considering we spend a large percentage of our time at work it's worryingly that nearly all of us feel stressed and annoyed by the people we work with.

"Anti-social behaviour is not only affecting the health of the nation but our economy too."
