Turnover is the most expensive line most reports never show. Replacing an employee – recruiting, onboarding, lost productivity – can, according to some HR-profession estimates, cost on average 5-6 months of their salary, and considerably more for a key person. Against that, any retention tool is cheap if it works. The question: what works?
Why does a raise’s retention effect fade?
Salary is comparable: within half a year the colleague views the market from the new level, and a competitor can simply outbid the number. A well-chosen benefit is harder to compare and sticks emotionally: the experience of “I got an MRI within two weeks through my employer” cannot be copied into a job offer.
The retention mechanics of health insurance
- It re-delivers its value at every use: each booking reminds people who provided it.
- It can extend to the family – and we hold on harder to what protects our family.
- It ends on exit (cover is tied to employment) – said honestly, this too nudges towards staying.
- Tier upgrades can be tied to promotion: the executive package becomes part of the career path.
Its place in the toolkit
It is no cure-all: with toxic leadership or below-market pay, no benefit retains anyone. The right order: sound base pay → health insurance as the core benefit → targeted extras (training, flexibility). On cost: it delivers equal value over 20% cheaper than salary – numbers in the pay rise vs insurance article.
Measure it
Retention impact is measurable: attrition before/after launch, exit-interview mentions, offer-acceptance rates. A year of data shows whether the programme works – and is the best argument at the next budget talk.
