It costs British business £9bn every year when employees call in sick, according to accountancy firm PwC.
They found one in three Brits admitted to claiming they were under the weather to their boss when they were really struggling with a hangover, fatigue or family commitments.
Hangovers were the most popular reason for feigning illness, while the average UK worker clocked in seven sick days every year, PwC said.
While only 8% admitted to taking time off to watch sport, PwC said this figure could rise with the Commonwealth Games in Glasgow and the Ryder Cup in Gleneagles this year.
