An overpayment that creates a debt to the Organization on the part of the staff member will normally be recovered immediately by means of deductions from salaries, wages, and other emoluments payable under the UN Staff Regulations and UN Staff Rules. However, the HR Specialist or the Resident Representative, as the case may be, may agree with the staff member who has received overpayments on: a) Alternative means of repaying the amount due, such as payment by bank transfer, bank cheque or personal cheque from the staff member; or b) Recovery in monthly instalments subject to the contract expiry date of the staff member; or c) Other methods of recovery at the disposal of the Organization.
The purpose of the rental subsidy scheme is to facilitate the settlement of new staff members and to encourage mobility within the UN Common System. It subsidizes the rental costs of eligible staff members whose rental accommodations are of a reasonable standard but cost significantly more than the average for the duty station. There are two different types of rental subsidy: one for staff members serving in Europe and North America and another for staff members serving outside Europe and North America.
A staff member who has not received an allowance, grant, or other payment to which he/she is entitled, does not receive it retroactively unless a written claim has been made within one year following the date on which the staff member would have been entitled to such payment.
