Employees want to be productive, but sometimes the allure of time-wasting activitiesis just too tempting. When that happens, it’s up to leaders to keep everyone on track.

According to research from Salary.com, 89 percent of employees waste at least some time at work every day. Thirty-one percent waste about 30 minutes, but the top 10 percent waste three or more hours each day. That extrapolates to more than 15 hours per week of wasted productivity, shedding light on the immense costs associated with poor time management.
