From signed contract to first day: how UN entry on duty (EOD) actually works

Signing the letter of appointment is not the end of the process — it starts a separate stretch of logistics and administration between that signature and an actual first day at a desk, known across the system as entry on duty (EOD). Little of it is written down anywhere a candidate can easily find, which is why it tends to catch first-time UN hires off guard more than any earlier stage. This guide walks through what actually happens in that window.

What “entry on duty” actually means

EOD is the specific date an appointment becomes effective — the date that starts pay, benefits, leave accrual and the probationary period clock, all at once. It is set on the letter of appointment itself and, depending on the organization, is confirmed either by a formal check-in with HR or simply by showing up and completing whatever in-person or remote registration the duty station requires. Nothing else in this guide starts until this date is fixed, so it is the one detail from the letter worth confirming is realistic well before it arrives.

Before EOD: the paperwork that has to land first

Depending on the duty station and your nationality, several administrative pieces need to be in place before or immediately at EOD, and they run on their own timelines outside the organization’s control: a visa or entry permit for the duty station (covered in the staff visas and diplomatic status guide, including the G-4 route and the UN laissez-passer), banking arrangements for salary payment, and — for an internationally recruited appointment involving relocation — the shipment and travel arrangements described in the assignment grant guide. Visa processing in particular can run longer than a candidate expects, which is the most common reason an agreed EOD date ends up pushed back by a few weeks rather than derailed outright.

What the first day and first week typically involve

The specifics vary by organization and duty station, but a recognisable pattern holds across most of them: an HR check-in to complete personnel records, issuance of an ID badge and building access, setting up IT accounts and system access (including the e-recruitment and performance appraisal platforms you will use throughout the appointment), and an orientation or induction briefing covering the organization’s structure, values and practical logistics of the specific duty station. Most of this is administrative rather than substantive — the actual first work assignment from a supervisor usually comes once the paperwork side is largely out of the way.

The mandatory online trainings almost everyone has to complete

Nearly every UN organization requires a short set of mandatory e-learning courses in the first weeks of an appointment, typically assigned automatically through the same system that will later run your annual performance cycle. These commonly include a security-awareness course covering personal safety and conduct at the duty station, an ethics and integrity briefing, and — across most of the system — a course on preventing sexual exploitation and abuse (PSEA). Exact course names and requirements vary by organization and by duty station’s security phase, but budgeting the first week or two for a handful of required modules, on top of the in-person induction, is a safe general assumption.

Probation and performance tracking start from day one

For a first fixed-term appointment, the probationary period covered in the ePAS and probation guide begins running from the EOD date, not from some later point once onboarding feels complete — so a work plan and the first performance check-in are usually set up within the opening weeks rather than left until the process has fully settled. Treating the onboarding period itself as part of that evaluation window, not a separate warm-up before it, is the more accurate way to think about the first months in post.

If you’re relocating: a shorter checklist

• Start the visa process the moment the letter of appointment is signed — it is the single most common cause of a delayed EOD date.
• Confirm with HR what is covered under the assignment grant and shipment entitlement, and what you need to arrange or pay for upfront and claim back later.
• Ask specifically about the duty station’s security phase and any mandatory in-person briefings tied to it, rather than assuming the standard online modules are the whole requirement.
• Keep copies of every document HR sends during this window — offer, letter of appointment, visa sponsorship correspondence — in one place, since you will be asked to reproduce several of them at different points in the first weeks.
