Typical proposal-form questions
- What was the annual staff turnover rate for each of the last three years, and how does it break down by department?
- What proportion of new hires have been with the company for less than six months?
- What onboarding and safety induction process is in place for new employees?
Evidence
- HR turnover and tenure report
- Onboarding and training programme documentation
- Prior-year claims experience by employee tenure, if available
Why it matters for underwriting
A high staff turnover rate is a recognised proxy for elevated operational and liability risk: new employees are statistically more likely to be involved in occupational accidents during their first months on the job because they are less familiar with equipment, procedures and hazards, and high turnover often signals broader issues such as inadequate training investment, poor safety culture or workplace strain that can also increase general liability frequency. Underwriters treat a persistently elevated turnover rate as a leading indicator of future claims frequency, even before loss history reflects it.
Capturing the attribute and evidence
Proposal forms typically ask for the annual turnover rate for the last one to three years, broken down by department or activity where turnover is concentrated in higher-risk roles. Underwriters review the HR turnover and tenure report alongside onboarding and safety induction documentation, and where available, cross-reference claims experience segmented by employee tenure to see whether new hires are disproportionately represented in past losses.
Effect on coverage, premium and conditions
Elevated turnover, especially concentrated in physically demanding or safety-sensitive roles, typically increases the liability and accident premium rate and can trigger a condition requiring a documented onboarding and safety induction programme. Coverage scope and sublimits are rarely affected directly, but a materially deteriorating turnover trend without a corresponding safety response can prompt closer risk engineering scrutiny at renewal.
Mitigation measures
Employers reduce this exposure through structured onboarding with mandatory safety induction before new hires are exposed to hazardous tasks, mentoring or buddy programmes pairing new staff with experienced colleagues, exit interviews to identify and address root causes of attrition, and monitoring turnover by department to target retention efforts where risk concentration is highest.
