Employee retention: what it depends on
Retention is an organization's ability to keep employees in a role over time. It's measured as the share still employed after 6, 12 and 24 months, and as early voluntary departure within the first year.
Early resignations most often stem from expectations that weren't aligned before hiring, weak onboarding, or a poor match with management and ways of working. Retention is therefore one of the outcomes a hiring decision is, in practice, measured against.
Definition
Retention
How retention is measured
| Measure | What it shows | Period |
|---|---|---|
| Retention rate | Share still employed from a given cohort | 6, 12 and 24 months |
| Early voluntary departure | Hires that didn't last through the first year | 0-12 months |
| Staff turnover by role | Whether the issue is organizational or specific to one role | Ongoing |
| Cause data from exit and stay interviews | Why people leave, and why they stay | Ongoing |
The typical causes of early departure
- Expectation gap: the role turned out to be different from how it was described during the process.
- Onboarding: unclear goals and a lack of follow-up in the first months.
- Management and team: ways of working and collaboration didn't match the employee's style.
- Development opportunities: no visible path forward.
- Terms: pay and flexibility - often the trigger, rarely the only factor.
What organizations do in practice
- Align expectations concretely during the process rather than selling the role.
- Set fixed check-ins after 30, 90 and 180 days with a consistent set of questions.
- Use stay interviews rather than exit interviews alone.
- Treat onboarding as part of the hire, not as an afterthought.
- Feed learnings back into the criteria for the next hire.
See the practical guide to retention for concrete steps, and employee outcomes for how data is collected.
Retention as an outcome in Hiring Intelligence
Retention is one of the outcomes that makes it possible to assess whether a hiring decision held up. By comparing the signals behind the decision with who actually stayed, patterns become visible within the individual company. It's context for the next decision - not a prediction of who will stay.
Limitations
- Retention is shaped by management, market and life circumstances, not just fit.
- High retention isn't a quality measure on its own - stagnation can also hide behind the number.
- Cohorts in smaller organizations are small, so single cases can skew the figure significantly.
RoleWise's approach
RoleWise connects the structured signals from the candidate conversation with the employee's actual development after hiring, including retention. The aim is a better basis for decisions next time - not surveillance of individual employees and not a prediction of future performance.

Frequently asked questions
What is employee retention?
Retention is an organization's ability to keep employees in a role over time. It's typically measured as the share of employees still employed after a given period, or conversely as staff turnover.
How do you measure retention?
Common measures include retention rate over 6, 12 and 24 months, early voluntary departure within the first year, and staff turnover by department or role. These figures should be read alongside cause data from exit and stay interviews.
Why do new hires leave early?
The most common patterns are expectations that weren't aligned before hiring, weak onboarding, unclear goals, and a poor match with management, team or ways of working. Pay is rarely the only cause.
What is a stay interview?
A structured conversation with a current employee about what keeps them in the role, and what would make them consider leaving. It surfaces information early enough to act on it.
Can retention be predicted from a job interview?
No, not with certainty. Retention is shaped by management, team, tasks and life circumstances after hiring. What you can do is see which signals recur among the people who stay in a given company - as context, not as a prediction.
