Bosses count the cost of Facebook

All that time you spend on Facebook and Twitter is costing your bosses money. How much? An eyewatering £1.4bn a year, according to a survey that found more than half of office staff spend 40 minutes a week on the social networking sites, the FT reports. "When it comes to an office environment, the use of these sites is becoming a productivity black hole," said Philip Wicks at consultants Morse, which carried out the research. Of course, allowing people a few minutes of relaxing downtime might actually enhance their overall productivity.
