Networking via social media at work is detrimental to the Russian economy, according to a survey.

      Companies lose up to RUR 300 billion, or $1 billion due to the idle time that their staff spend on websites like Facebook, Vkontakte or Twitter, says a study by FBK, a major Russian auditing firm.

      Employees waste some 53 hours a year on browsing info irrelevant to their job, and at least 30 percent of employers have already put online restrictions in place.
