Twitter and other social networking websites cost UK businesses more than £1.38 billion a year in lost productivity, a new study suggests.
A survey of nearly 1,500 office workers found 57% used the websites during the day for personal use.
The research, commissioned by IT services and technology company Morse, showed the employees spent about 40 minutes a week viewing the pages.
Based on the average wage of an office worker, this cost firms £1.38bn a year, Morse said.
“The popularity of social networking sites such as Twitter and Facebook has grown considerably over the last couple of years. However, with it has come the temptation to visit such sites during office hours,” said Philip Wicks, a consultant at Morse.
