Alternative Schedule Category Work Schedule Eligibility Profile not impacting SSP Calculation

Summary:

In the UK it is possible, at the absence plan level, for a stautory Sick Pay plan to use an 'Alternative Schedule Category' so that, when assigned to a Work Schedule, it uses that to determine the working days, and not the Work Schedule either assigned to the employee assignment, or at another level which would normally be used.

When creating the Work Schedule, I am assigning the Category, which has been configured as 'SSP', a requirement for this working

In one example, if I configuring the Work Schedule based on specific Departments , where the employee resides in one of those associated with the Work Schedule, then it utilises this work schedule instead of their normally defaulted one.
