The user permissions groups can be set by clicking on an employee's name in the Employees tab. Then click Teams & permissions in the menu bar.
Standard there are four permission groups.
Of these groups, the Employee group has the least rights.
In Team you can indicate which department(s) the employee will return in the schedule and timesheet can be added. An employee must return in at least one team but can have multiple permissions groups on different departments.
Which permissions the different user groups have, can be viewed and configured under: Settings > Permissions.
The rights for an employee can be set by location or department.
