Employee turnover is the percentage of staff who leave the company in a period. It is calculated by dividing yearly departures by average headcount and multiplying by one hundred. The number alone says little: what matters is when people leave, because early and late departures have different causes.
The three exit moments
Before 90 days. Almost always an expectation or welcome problem: the role was not what was described, or the person never came to feel part of it. It is the most expensive exit because recruiting and training costs were never recovered.
Between 1 and 3 years. Usually lack of horizon: the next step is not visible.
After 5 years. It is recognition: the person feels their tenure stopped meaning anything.
What to do at each stage
For early exits, onboarding is the most direct lever. Have the workstation ready, assign someone as a reference for the first week, and have a welcome kit waiting: cheap signals that the arrival was planned.
For mid-tenure stagnation, the development conversation is what retains, not the object. The emotional salary guide applies directly here.
For tenure, formal years-of-service recognition. A recognition plaque given publicly signals that the trajectory is seen. See also anniversary recognition.
The exit interview is your best data
Always run it, with someone other than the direct manager, and log the cause against a closed list of reasons. In six months you will have the real pattern of why your people leave, which rarely matches what was assumed. Pair with how to improve workplace climate.
