According to the CBI: "the average UK office worker spends an hour and a half a week of work time surfing the web for personal use, at a cost to the economy of £10.6bn a year."
It is estimated that employers across the public and private sectors lose 4.4 per cent of working time in this way, which accounts for 95 minutes a week, or ten days a year, at an average annual cost of £939 per employee.
See Over 90 minutes a week spent on personal websurfing at work.
What the CBI fail to mention is that employees are also said to contribute £26bn a year in unpaid overtime, or 7 hours and 24 minutes of unpaid work each week.
I'm not quite sure why the CBI is moaning so much!
