When a permanent staff member that is not a casual employee and is entitled to sick leave calls in sick, the shift still needs to be recorded and paid for as a sick day.
To do this, they will need to be removed from their shift and replaced by a new staff member so the client isn't charged for the sick staff members non-attendance.
When this is done, the sick staff member is no longer rostered on but we need a way to record their shift so they still get paid.
Admins can create a new Client and call it 'Sick Leave' for example. Then they can assign the sick staff member to the 'Sick Leave' client. When they run the payroll, the hours will be applied to staff member either under their default pay group, or they could create a new pay group called 'Sick Leave' if the pay entitlements are different.
