The eighteen-month exit cliff, and what sits under it
Senior joins that leave cluster around the same point. The cause was usually written into the offer, not the onboarding.

Key takeaways
- Senior joins that leave don’t leave at random. They cluster around a predictable window after the honeymoon ends.
- The cause is almost always written into the offer, not the onboarding — a scope that was oversold to close.
- The cliff is preventable, but only upstream: an honest mandate beats any retention save eighteen months in.
The exits cluster, and the cluster has a shape.
Track the senior hires who leave a GCC and a rhythm surfaces. Very few go in the first quarter — the goodwill is still warm and the role still feels new. The departures gather later, around the point where a leader has stopped learning the place and started measuring it against the seat they were promised. That window is where the honest read of the job finally arrives.
By then the person knows what the mandate actually is, not what it was described as in the closing conversation. If the two match, they stay and compound. If they don’t, the exit is already forming — quietly, months before the resignation lands on a manager’s desk.
“The eighteen-month exit is rarely a surprise to the person leaving. It was decided the day they signed for a role that had been dressed up to close.”

The cause sits in the offer, not the onboarding.
When a senior hire walks off the cliff, the instinct is to audit the onboarding — the buddy, the first-90-days plan, the town halls. Useful, but late. The real defect usually predates day one. Somewhere in the pursuit, the scope grew to match what the candidate wanted to hear: a mandate with more ownership, a charter with fewer dotted lines, a parent that would defer more than it does.
Onboarding can’t repair a promise the role was never able to keep. The centres that flatten the cliff do it before the offer, by describing the seat as it genuinely is — scope, constraints, reporting lines and all — and letting the candidate opt in with eyes open.
Reading the cliff early is a hiring discipline.
The tell isn’t a survey score. It’s a senior who has stopped proposing and started delivering exactly what’s asked — competent, disengaged, waiting. On most of the exits we’ve tracked, that flattening showed up long before the market conversation did.
You can’t manage the cliff at the edge of it. You manage it in the search — by hiring for the seat that exists and refusing to sell the one that doesn’t. Everything after that is retention theatre against a gap you built in yourself.

The 18-month exit cliff is real. The cause isn't what HR thinks.
Across the GCCs we track, senior attrition clusters at a predictable point. The triggers group into four things — and only two are inside HR’s control.
Counter-offers are working again. Quietly.
Counter-offer bite rates have moved. The market signal beneath that number matters more than the number itself.
