Imagine a CHURn making butter – it stirs milk violently until it separates. Similarly, a company with high 'churn' sees people 'stirred' out of it.
Conceptual Metaphor
CHANGE IS MOTION (specifically, turbulent, wasteful motion). ORGANIZATIONS ARE CONTAINERS (from which people/things are churned out).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating the business sense as 'текучесть кадров' (staff turnover) only; it applies broadly to customers, subscribers, etc. The verb 'сбивать' (as in butter) is correct for the literal sense but not metaphorical ones.
Common Mistakes
- Using 'churn' to mean simple 'change' without the connotation of turbulence or loss. Confusing 'churn out' (produce) with 'churn up' (disturb).
