After-hours bonuses should not be permitted

For us, the day is completely finished when the end of the working day is booked and the employees (approx. 1,800 in total) are also trained in this way. Unfortunately, it is still possible to enter allowances after the end of the working day. In our view, this should not be possible at all, but given the large number of your customers, it would at least make sense to have an option that allows it or not.
