You have just 44 days to influence a new hire's decision to stay long-term

Most organisations put significant effort into hiring. The job ads, the interviews, the offer negotiations. And then, the moment someone accepts - the real work begins.

Because what happens next, in those first few weeks, shapes everything. Whether a new employee becomes a long-term performer or quietly starts looking elsewhere often comes down to the quality of their onboarding experience.

And the window to make an impression is smaller than most people realise.

When someone joins your organisation, you have - on average - just 44 days to influence their decision to stay long-term (BambooHR).

44 days. Just over six weeks. That's it.

But here's the flip side: when organisations deliver a great onboarding experience, employees are 69% more likely to stay for at least three years (SHRM). The window may be small, but the opportunity is huge.

So, what does great onboarding actually look like?

Over the years, working with organisations on their employee experience, I've thought a lot about what makes onboarding genuinely work. The organisations that get the most from it aren't necessarily the ones with the biggest programmes or the most resources. It usually comes down to one thing... intent.

When I think about the elements that matter most, it consistently comes back to three things.

1. Competency

Setting clear expectations from the start. Defining what good looks like in this role. Giving people the training, tools and support they need to do their job well - as quickly and as confidently as possible. When people feel capable, they feel valued. And when they feel valued, they stay.

2. Coherence

Helping people understand how their role connects to something bigger. The purpose, the direction, where they fit within it. Not just what they do, but why it matters. People who feel their work has meaning are far more likely to be engaged - and far less likely to walk out the door.

3. Connection

Creating genuine opportunities for relationships to form - building a sense of belonging and an authentic feel for the culture. This is often the hardest to manufacture and the easiest to neglect. But it might be the most important of all.

When the three Cs work together

When Competency, Coherence and Connection are all present throughout onboarding, it stops being a tick-box process people have to get through, and becomes an experience that genuinely sets them up to do their best work.

The new hire feels capable in their role. They understand where they fit and why it matters. And they feel like they belong - not just as a resource, but as a person.

Onboarding as a designed experience

The most powerful shift an organisation can make is to treat onboarding not as a process to complete, but as an experience to design.

That means thinking beyond the welcome email, the org chart and the first week diary. It means asking a more purposeful question: what do we want this person to know, feel and be able to do by the end of their first 44 days? And then working backwards from that.

Onboarding that's been intentionally designed - structured, personalised, and built around the new hire's experience - is what turns a promising start into a long-term relationship.

The business case speaks for itself

Retention isn't just a people priority - it's a commercial one. The cost of replacing an employee is estimated to be up to 200% of their annual salary, depending on seniority. When you factor in recruitment fees, lost productivity, onboarding time and the impact on team morale, the numbers add up fast.

Seen through that lens, onboarding isn't a nice-to-have. It's one of the highest-leverage investments a people team can make.

A question worth sitting with

Think about someone who joined your organisation recently.

What did their first 44 days actually feel like? Did they have clarity on what good looked like in their role? Did they understand where they fit and why their work mattered? Did they feel like they genuinely belonged?

Those questions are worth asking. Because the answers will tell you exactly where to focus to make the next person's experience even better.
