Sheffus Links: Employees work extra hours on mobile email, calls

A new survey of 1,000 U.S. workers found that people spend an average of seven extra hours a week -- almost another full day of work -- answering calls and email on a mobile device outside of regular working hours.

That means some people are spending nearly 30 hours more a month, or 360 extra hours a year, on calls and emails, according to the poll commissioned by Good Technology, a mobile device management software maker.
