Turns out it may not be so bad when employees use the Internet to check personal e-mail and do other non-work activities. A study appearing in the June issue of CyberPsychology and Behavior finds that virtually everyone is guilty of sometimes using the Web on the job for things that could hardly be called work-related. Investigators also found that most people really aren’t slackers. In fact, employers who allow staff to efficiently handle a few personal errands online see a residual benefit: workers get back to focusing on their jobs more quickly than if they were required to go off-site.
