10 A former staff member who is re-employed will be given a new appointment or, if re-employed within twelve months of separation they may be reinstated, at the option of the Organization, in accordance with the provision of Staff Rule 470, which are further elaborated below.
Re-employment
20 If a former staff member is re-employed, they will be given a new appointment and their conditions of service determined without regard to any period of former service, except that former service may be considered when establishing the staff member's step at the grade of the position to be occupied in accordance with the provisions of Staff Rule 320.1 and when determining their record of mobility.
30 A former staff member who has accepted a mutually agreed separation is precluded from renewed employment with WHO for a period as specified in the separation agreement (normally three years). A former staff member who is re-employed before the end of the period specified in the separation agreement will refund to the Organization any termination indemnities corresponding to the period of separation not served. Exceptional requests for re-employment before the expiration of the period specified in the separation agreement must be addressed to Director, HRT for approval. Such request must be fully justified and be accompanied by all relevant documentation.
40 If a former staff member is reinstated within 12 months of being separated from service it will be so stipulated in their letter of appointment. On reinstatement, the staff member's service will be considered as having been continuous, and the staff member will be required to return to WHO payments received on account of separation including repatriation grant, repatriation travel, relocation shipment, termination indemnity (inclusive of the additional 50%) and accrued annual leave.
50 The interval between separation and reinstatement will be charged, to the extent possible and necessary, to annual leave with any further period charged to special leave without pay under Staff Rule 650. The staff members sick leave credit under Staff Rule 740 at the time of separation will be re-established and participation in the pension fund will be governed by the Regulations of the Fund. Coverage under any insurance will not apply during the period that is charged to special leave without pay. However, staff members who wish to have the period of special leave without pay count for purposes of contributory service may send a written request to the Coordinator, Insurance and Pension. The staff member will be required to pay both their and the organization's contributions for all insurance and they will be notified of the amounts and modalities of payment of the relevant contributions.
