Human rights screening

Individuals who seek to serve with the United Nations in any individual capacity will be required, if short-listed, to complete a self-attestation stating that they have not committed, been convicted of, nor prosecuted for, any criminal offence, including sexual exploitation and abuse, and have not been involved, by act or omission, in the commission of any violation of international human rights law or international humanitarian law, including sexual exploitation and abuse.

Conflicts of interest screening

All United Nations staff members are expected to uphold the highest standards of efficiency, competence and integrity. Senior leaders in particular, have the responsibility to serve as role models in upholding the organization’s ethical standards.

A conflict of interest occurs when, by act or omission, a staff member’s personal interests interfere with the performance of his/her official duties and responsibilities, or call into question his/her integrity, independence and impartiality. Risk for conflicts of interest may arise from a staff member’s engagement in outside (non-UN) employment or occupation; outside activities, including political activities; receipt of gifts, honours, awards, favours or remuneration from external (non-UN) sources; or personal investment. In particular, no staff member shall accept any honour, decoration, favour, gift or remuneration from any Government (staff regulation 1.2 (j)).

Where a real or perceived conflict of interest does arise, senior leaders are obligated to disclose this to the organization without delay. In order to avoid real or perceived family influence or preferential treatment and conflicts of interest that could stem from such situations, the UN Staff Rules provide that appointments “shall not be granted to anyone who is the father, mother, son, daughter, brother or sister of a staff member” (staff rule 4.7(a)).

Short-listed individuals will also be required to complete the pre-appointment declaration of interests for senior positions to identify possible conflicts of interest that may arise and to proactively prevent and manage, as much as possible and in a timely manner, situations in which personal interests may conflict or appear to conflict with interests of the United Nations, should the individual be appointed to this position.
