UN conduct and discipline, and PSEA, explained

“Conduct and discipline” and “PSEA” come up constantly in UN job postings, mandatory training modules and mission-specific onboarding, and applicants often assume they mean the same thing as the Ethics Office covered in the ethics and financial disclosure guide. They don’t. This guide separates the offices, explains what the zero-tolerance policy on sexual exploitation and abuse actually prohibits, and covers the inter-agency misconduct screening that now sits inside the hiring process itself.

Three different offices, three different jobs

The UN runs several oversight functions that applicants tend to lump together. The Ethics Office handles conflicts of interest, financial disclosure and protection against retaliation for whistleblowing, covered in the whistleblower protection guide. Conduct and Discipline units and teams — at Headquarters and in field missions — track allegations of misconduct, run prevention and awareness training, and coordinate the organization’s response, but generally do not themselves investigate. Investigation of serious misconduct, including sexual exploitation and abuse and sexual harassment, is normally the job of the Office of Internal Oversight Services (OIOS) or an equivalent investigative function at agencies outside the Secretariat. Knowing which office does what matters if you ever need to report something, or if you’re asked about it in an interview for a field or HR-adjacent role.

PSEA: the zero-tolerance policy, in practice

PSEA stands for Prevention of Sexual Exploitation and Abuse. The policy — built on a foundational bulletin issued in the early 2000s and reinforced repeatedly since — prohibits sexual activity with beneficiaries of UN assistance, any exchange of money, goods, employment or services for sex, and any sexual relationship that involves an inherent power imbalance, such as one between UN personnel and the people they are mandated to help. It is described as “zero tolerance” because a single substantiated case is treated as grounds for dismissal and referral for possible criminal accountability, not a disciplinary sliding scale. PSEA is distinct from sexual harassment policy, which addresses staff-on-staff conduct and sits under its own administrative issuance — the two are often trained together but are legally separate categories with separate reporting routes.

Conduct and Discipline Units and Teams in the field

Peacekeeping operations and many special political missions run a dedicated Conduct and Discipline Team or Unit, coordinated centrally by a Headquarters-level Conduct and Discipline function. Their work is largely preventive: mandatory training for incoming personnel, awareness campaigns for the local population on how to report, and tracking allegation trends across a mission. For uniformed personnel — troops and police — the UN generally lacks criminal jurisdiction, so a substantiated allegation is referred to the individual’s troop- or police-contributing country for national investigation and any prosecution, a jurisdictional split that doesn’t apply to civilian staff. This uniformed/civilian distinction runs through several other policies too, covered in the peacekeeping civilian-versus-uniformed guide.

OIOS: who actually investigates

Within the UN Secretariat, the Office of Internal Oversight Services investigates allegations of serious misconduct, including sexual exploitation, abuse and harassment, and refers substantiated findings into the disciplinary process — which can, on appeal, eventually reach the UN Dispute Tribunal and Appeals Tribunal described in the administration-of-justice guide. Funds, programmes and specialized agencies outside the Secretariat generally run their own equivalent investigative function rather than referring cases to OIOS, so the exact office handling a complaint depends on which organization employed the person involved.

Misconduct screening before you’re hired

This is the part that most affects a job applicant rather than a serving staff member. The UN system now runs an inter-agency misconduct screening check as part of pre-employment due diligence, alongside the reference and background checks described in the reference-checks guide: a candidate’s name is checked against a shared record of substantiated sexual exploitation, abuse or sexual-harassment findings across participating UN entities before an offer is finalized. A clean record at one organization is not itself evidence, since the check is precisely what verifies that — but it means a substantiated finding at one UN organization can follow a candidate into an application at a different one, which was not reliably true before this kind of shared screening existed.

Reporting channels and victim assistance

Every mission and most agencies publish a reporting channel for SEA or misconduct concerns — a hotline, a designated focal point, or a direct route to OIOS or the equivalent investigative office — and a UN Victims’ Rights Advocate function exists to support people affected by sexual exploitation and abuse specifically, separate from the disciplinary process against the accused. If you’re an applicant, intern or contractor rather than staff, the same channels are generally open to you: the policy protects anyone affected by or reporting misconduct, not only employees.

How to actually prepare

If a role touches field operations, HR or programme management, expect a competency-based interview question on ethics or PSEA awareness — the panel is checking that you understand the zero-tolerance framing and know how to report, not testing memorized policy numbers. Build that into the evidence-and-examples discipline covered in the competency-based interviews guide, and expect the standard mandatory PSEA and ethics training modules in your first days on the job, described in the onboarding and entry-on-duty guide.
