Onboarding
Long before the probation period ends, most new hires have quietly made up their minds. Here is what the research says they are looking at.
There is an uncomfortable number in the onboarding research: roughly one new hire in three leaves within the first ninety days. Not because the job turned out to be impossible, and usually not because of money. They leave because, somewhere in the first weeks, they concluded that this was not the right place — and nobody noticed in time to change their mind.
The timing is faster than most HR teams assume. Around seventy percent of new hires decide whether a job is a good fit within the first month, and nearly a third know within the first week. Whatever you were planning to do in month three, they will not be waiting for it.
The most common answer is unglamorous: training. Sixty percent of people who quit in the first three months said the training was missing or disorganised. Not too hard, not too fast — disorganised. Nobody had decided who would explain what, so everyone assumed someone else had.
The second answer is belonging. Ninety-one percent of new hires who got a real introduction to the company culture say they feel connected to their workplace, against twenty-nine percent of those whose onboarding was poor. For someone who has also moved country, this gap is wider still: they are learning the company, the language and the city at the same time.
Structured onboarding through the first three months makes employees 69% more likely to stay for three years.
One intervention keeps appearing in the data. Give the new person a buddy — a colleague who is not their manager — and make sure they actually talk. Among new hires who connected with their buddy more than eight times in the first ninety days, ninety-seven percent said it helped them get up to speed quickly.
The reason is simple. There are questions people will not ask their manager: Is it normal to leave at six? Does anyone actually read these reports? Who do I ask when the system logs me out? A buddy is where those questions go. Without one, they go nowhere, and the answers get invented.
Yet roughly half of companies run onboarding for two weeks and consider the job done. The recommendation from the research is a minimum of ninety days, with lighter check-ins running through the first year. That does not mean ninety days of training. It means someone whose job it is to ask, at week two, week six and week twelve: how is it going, honestly?
And it means asking in a way that gets a real answer. A new hire — especially one working in a second language, in a new country — will almost always say fine to a question like is everything fine? The useful questions are narrower: What was confusing this week? What did you have to ask twice? Who have you not met yet who you probably should? Those get answers you can do something with, while there is still time to head off the resignation nobody saw coming.
