New data on the workplace by Evolv, a startup that monitors hundreds of metrics from Fortune 500 companies, suggests that social media should not be considered the the bane of employee productivity. Rather, the more social networks an employee uses, the more productive they are.

In the study it was found that employees who regularly used up to four social networks — such as Facebook, Twitter, Pinterest or LinkedIn — made more sales or handled customer service calls faster than those who weren’t on any social networks. Those who used five social networks or more were slightly better at converting sales and handling customer service than employees on four or fewer networks, by 1.5% and 2.8% respectively, Mashablereported.

In addtition to improved productivity, employees in the social media camp also had a longer tenure. The employees who used four social networks stayed at the company longer, (an average 94 days of tenure with a company compared to 83 days for those who shunned social media). For those who used five social networks, their average tenure was slightly lower at 92 days.

Evolv goes on to suggest that the increases in productivity and tenure may simply be a reflection of the employee’s computer literacy and sociability, and therefore greater ability to provide better service and handle customers better.
