Can I sort employees into employee groups or departments?

On DeskTime, you can group employees into Employee groups, such as "Marketing", "Sales", "Management", etc.

In order to create an Employee group, go to Settings-> Groups, and click on the "Add new group" button. To assign an employee to a particular employee group, go to Settings-> Employees-> Edit-> Group

For each employee group, you can then define which applications are productive, unproductive or neutral. For example, Facebook and Twitter could be a productive application for social media managers while it would be unproductive for others. See more information on how to change productivity settings here.
