Preboarding

Between acceptance and the first day

Preboarding describes how an employer prepares for a new colleague after an offer is accepted and before work begins. The term is often used for practical information, contact with the team and arrangements for the start. SHRM includes pre-start preparation within the wider onboarding process; organisations may draw the boundary differently (SHRM).

Make the start easier to navigate

A contact person can confirm where and when to arrive, what to bring and whom to ask if plans change. The team can also share an outline of the first day or week, while making clear which details are still undecided. This gives the new colleague useful context without pretending the whole role can be learned before it starts.

Paperwork that cannot wait for day two

Some of preboarding is a legal deadline rather than a courtesy.

• UK right to work. You must check that someone is allowed to work for you in the UK before you employ them, for example online with their share code, by checking original documents or through an identity service provider (GOV.UK).
• Written statement (Great Britain). The principal statement, covering pay, hours, holiday, place of work and start date among other things, is due on the first day of employment; the wider written statement follows within two months (GOV.UK). Northern Ireland has no day-one rule: the statement is due within two months of starting work (nidirect). Preparing it during preboarding avoids a scramble on the morning itself.
• US Form I-9. The employee completes Section 1 no later than the first day of work for pay, but you may not ask someone to fill it in before they have accepted the offer (USCIS). Section 2, the employer’s document review, is due within three business days of that first day of work for pay (USCIS).

Keep preparation proportionate

Preboarding is a transition, not a request to do the job in advance. Avoid sending work that belongs to the employment itself, and do not treat silence as proof that someone has lost interest. If a start date or arrangement changes, a direct check-in can clarify what happened and what the person needs.

Draw the boundary where work begins

Preboarding and onboarding overlap in some organisations. A practical distinction is that preboarding prepares the person and the workplace for day one; onboarding helps the colleague learn the role, relationships and routines once work begins. The handoff should make the next contact and first responsibilities clear.
