What are we measuring?
Voluntary turnover — the share of people who leave by choice each year, not through redundancy or restructuring.
- Every voluntary leaver carries a replacement cost: recruitment, onboarding, ramp-up, and lost knowledge.
- It compounds — the longer language barriers limit engagement and progression, the more embedded it becomes.
