In Strobbo you can set up per employee if his/her overtime needs to be tracked or not.
This option exists because you might not need to track everyone's overtime, for example only for permanent employees and not for students.
You can find information on how the overtime is calculated in this article.
You can set up for which employee the overtime needs to be tracked by following these steps:
Choose in the menu for Management - Users.
Click on the right on the 'edit icon' (pencil) of the employee for whom you want to track the overtime.
Choose the tab of your establishment and scroll down until you see 'overtime'. Check the box.
Enter from when the overtime or negative time will start to count.
When you set up for example 38 and 38, when this week the employee works 38:05, 5 minutes overtime will be calculated. When the employee works 37:55 hours, 5 negative hours will be calculated.
So when you set the negative hours to 37 and the overtime to 39, nothing will be calculated if that employee works 38:05.
Attention: you need admin rights to set up the negative hours and overtime.
