(Newsroom America) -- If you've ever felt like there's not enough time in the work week, your cell phone and list of errands may be to blame. Professionals surveyed by staffing firm OfficeTeam said they squander an average of 56 minutes per day, or the equivalent of nearly five hours a week, using their mobile device for non-work activities in the office.
In contrast, senior managers estimate their staff members spend 39 minutes each day on their cell phones during business hours.
Workers also admitted to clocking 42 minutes a day on personal tasks. All in all, the average employee could be wasting more than 8 hours per work week on activities unrelated to the job.
Employees ages 18 to 34 rack up 70 minutes on mobile devices and 48 minutes on personal tasks each work day, the most of all age groups.
While 62 percent of managers think staff spend the most time on social networks when using their own mobile devices during business hours, workers said they're most occupied by personal email (30 percent).
Male employees most frequently check non-work email on their cell phones (32 percent), while females browse social networks more (33 percent).
Workers reported social media (39 percent) and entertainment websites (30 percent) are most commonly blocked at their companies. Nearly half of respondents (48 percent) indicated their organization doesn't restrict access to online content.
More than half of professionals (58 percent) often use their personal devices at work to visit pages that are banned by their company, a 36-point jump from a 2012 survey. Only 39 percent of managers think it happens that commonly.
Sixty-eight percent of male workers frequently use their cell phones to access blocked websites in the office, compared to 43 percent of females.
"It's understandable that employees may occasionally use their mobile devices or attend to personal tasks during business hours. But these activities can easily become big distractions," said Brandi Britton, a district president for OfficeTeam.
"To best manage their time, staff can take advantage of breaks during lunch and throughout the day to catch up on non-work email or errands."
