What should onboarding a new employee look like in the first 90 days?

No law or standard sets a length. What is clear is that a first day is never enough. A welcome pack, a tour of the building and a laptop that works are a start, but most of what someone hears on day one is gone by the end of the week. Onboarding is the period in which a new employee learns what is expected of them, how things really work at your company and who to go to.

We work with ninety days as the minimum. It is not a scientific threshold but a practical one: long enough for someone to deliver a first result, short enough for a manager to keep it up. For complex roles it runs longer. Talya Bauer, professor of management and author of the SHRM Foundation's guide to onboarding, gives L'Oréal as an example, where new employees go through an integration programme that lasts two years.

Why those first months carry so much weight is covered in our article on why new employees leave in their first year: the decision to go is usually made in the first weeks, even when the resignation comes much later.

The 4 Cs come from the same guide by Bauer, published in 2010. They describe four levels at which you can help a new employee settle in.

Compliance is the lowest level: the rules. The contract, the house rules, the safety briefing, access to systems. It has to be right, but nobody stays with an employer because their badge worked on day one.

Clarification is about the job itself. Does the new employee understand what is expected, and what they will be judged on after three months or so? This is where it goes wrong most often, because the manager assumes the job advert already said it.

Culture is how things work here, on paper and off it. How quickly do you answer an email, who really makes the decisions, can you skip a meeting?

Connection is the network: the colleagues you can turn to and the people you need to know to do the job.

Bauer writes that many organisations never get past the first two. She calls that passive onboarding: there is some explanation of the role, but culture and connections are left to chance. Those are exactly the two that decide whether someone feels at home after three months.

A programme does not need to be a forty-page binder. This is the outline we recommend to employers, in four steps.

Sort everything out before day one. Contract signed, laptop ready, accounts created, and a schedule for the first week in the new employee's inbox a few days ahead. Agree who welcomes them on the first morning. Bring along what was agreed during selection; how to record that is covered under screening and candidate follow-up.

Make the first thirty days clear. Write down what someone should be able to do after thirty days and go through it in the first week. Assign a buddy who is not their manager. At the end of week one, hold a short conversation: what is better than expected, what is worse?

Give days 31 to 60 to the culture. The new employee now works independently. Let them spend a day with another department and take them to meetings they do not formally need to attend. Schedule a second conversation around day 45.

Close days 61 to 90 with an honest review. Put the job next to what the advert promised. What matches, what does not, and what do they still need? This is not a formality: it is where you hear what will make your next job advert better.

You can see that the start counts in how we judge recruitment too. We only count a hire once someone has been hired and has actually started, as we explain on our results page.

What is the difference between onboarding and training?

Training is about the work: the tasks, the systems, the procedures. It sits mostly under the first two Cs, compliance and clarification. Onboarding is broader and lasts longer. It also covers the company's culture and the colleagues someone needs to get to know. An employee can be fully trained and still feel like an outsider after three months.

Who is responsible for onboarding?

The line manager, even when HR designs the programme. HR handles the contract, the systems and the schedule, but only the manager can explain what is expected of someone and how the team works. If an RPO partner runs your recruitment, agree who stays in touch with the new employee between signing and the first working day.

How do you know whether onboarding works?

Look at two things: who leaves again within a year, and what new employees say in the day 90 review. The first number arrives late, the second arrives in time to change something. Put the answers side by side and look for what keeps coming back. Terms such as time to hire are explained in our glossary.
