As much as 17 per cent of the UK workforce will go to work with a hangover this month as the Christmas party season gets into full swing, according to new research.
For workers aged between 18 and 25 the figures are even more shocking, with 15 per cent of the employees surveyed by PruHealth admitting to going to work hungover once a fortnight.
Those who do go to work feeling less than their best after a night on the tiles can expect it to affect their performance, with 22 per cent of respondents saying that they make mistakes at work when they are hungover.
Around 83 per cent of employees who have been hungover at work say that it makes a difference to the way that they work, with 33 per cent saying that they drift off and don't work at their usual pace, while 28 per cent suffer from headaches and can't concentrate.
Nick Read, PruHealth direct marketing and partnerships director, said: "While we appreciate everyone will want to enjoy a drink at Christmas, it is worth pointing out that not only does binge drinking affect your productivity, it also makes you feel terrible the following day and, most importantly, is bad for your health."
Among the top excuses heard by employers at this time of year were that staff members had a cold, were experiencing transport problems such as a broken-down car, or that they were going to the doctor's.
