How to handle Configuration for 3 absence types for payroll purposes

Summary:

Need to configure 3 absence types

Content (required):

We have 3 absence types.

1. Sick Leave Full Paid

2. Sick Leave Half Paid

3. Sick Leave Unpaid

We need to keep them as 3 separate absence types for integration to 3rd party payroll purposes. Thus we cannot use 1 absence type with 3 absence plans.

An employee can only apply for Sick Leave Half Paid once all the Sick Leave Full Paid days have been used (balance =0) and can then only apply for Sick Leave Unpaid once the Sick Leave Half Paid balance is also = 0.

How would you suggest I handle this configuration?
