Recalculate accrual balance based on other absences

Summary: We would need to (re-)calculate accrual balances based on other absences being taken.

Content (please ensure you mask any confidential information):

When an employee is sick for a continous period of 1 month, the accrual for other absence plans should be adapted to consider this period.

E.g. we have an accrual for number of hours worked on top of the weekly standard working hours, but when an employee is sick for a continous month, this accrual should not consider that month in the accrual. Has anybody been able to achieve this (or something similar)?
