For each time off type, you can specify if accruals are prorated at the beginning and end of the policy, or are never prorated. If accruals are NOT prorated: The full accrual amount will be added to the user's time off balance on each accrual date.
If accruals are prorated: On the policy's first accrual date, and on the policy's end date, the amount the user accrues is proportional to the amount of time the user worked in the preceding "accrual period" (the length of time between scheduled accruals).
A policy's end date occurs either when a new policy becomes effective, or the employee's employment end date is reached.
The time off earned between the last accrual and the policy's end date is accrued on the policy's end date, even if it is not a scheduled accrual date.
