Ms Oonagh McPhillips:

It arises where employees exceed the sick leave thresholds; where they have failed to provide certificates for sick leave; where they might take unplanned sick leave at short notice or where there is late notification of exit cases by an employer or his or her manager. Some mistakes can occur in the PeoplePoint payroll process also. I know that the committee has heard from the National Shared Services Office, NSSO, in that regard. There can be some delays in instructions being issued or a delay in the Payroll Shared Service Centre, PSSC, in implementing the instructions. They are the circumstances in which the overpayments arise.
