You can setup your employee's working days and work hours by clicking on the settings icon on the top right corner of the Worktime solution.

Select which days of the week are considered working days.

Input here how many hours total is a work day supposed to be.

Input here at what time does the work day start and and what time does it end.

If you wish to notify your drivers/employees that the work day has started, mark the "Fixed hours" checkbox and they will receive a notification on their app.
