hello community,

In our company we track the attendance from the employee with the kiosk mode. For employees who work always at the same days it works fine. The Overtime gets correctly calculated to the referring work time of every day.

Now to our problem:
We have multiple workers, which work part time (e.g 50% (21h/week)). But they can choose every week by themselves on which day they want to work. So maybe they work for one week 2.5 days and the other 5 half days. We don't work with timesheet, we only want to track the attendance and calculate the overtime. How can i achieve this, without changing the work time for the employee every week.

How i would like it:
It would work, when the overtime for a worker everyday gets calculated. So if he doesn't work at monday he would be 4 hours in minus (50% worker). But if he would work on tuesday for 8h he is at 0 again. 

But at the moment Odoo don't subtract from the overtime, when the worker didn't checked in, even when a work time is set.

Has anybody a solution for this?
