Hi @Wendy,
I am not sure which question you are referring to, if you could add the link here in the comments that would be great. :)
Regarding the situation, please keep in mind that with the normal absence management, the prorated entitlement only gets reduced for days which are closed in the work schedule.
When taking leave, full days get deducted for all open work days, no matter if the employee is working only 4h or the full 8h. Half days can only be taken on the first and the last day of a period, or also on single days.
We do have a Beta Test running for hourly absences, here you can find more details about the scope and how it will look like.
Until then you need to either give the employees a regarding higher leave entitlement, eg. like a full time employee when working on 5 days a week. Or the employees only need to take holidays for part of the week and enter another absence type to inform their colleagues about their absence on the other days. If you don’t have an absence type, only to inform the colleagues, you need to create a new one. Please make sure that for the absence type the question Consider attendance days during absence period as overtime? is answered with no. As it is not supposed to have an impact on the target hours in attendances and is not being paid.
When choosing to enter 2 different absence types, it is best to approach the employees and agree on the amount of days and how exactly they need to enter their vacation.
Does this answer your question fully and help you solve the situation? :)
Cheers,
Lena
