Should a 10% reduction in staff be considered a layoff?  In one sense, yes, because on a particular day, a collection of employees no longer work at a startup. But a 10% layoff shouldn't confer messages of a financially strapped business. 

Consider the average annual employee attrition in a startup ranges between [13%](https://www.linkedin.com/business/talent/blog/talent-strategy/industries-with-the-highest-turnover-rates) and [25%](https://www.founderscircle.com/high-startup-turnover-rate/). A 10% reduction-in-force (RIF) is less than the quantum of employees the business would have expected to lose throughout the year. 

Many established businesses [force rank staff](https://en.wikipedia.org/wiki/Vitality_curve), a human resources discipline which recommends an annual 10% reduction in their staff as a matter of course. 

Jack Welch, former CEO at GE, dubbed it the [Vitality System or Vitality Curve](https://en.wikipedia.org/wiki/Vitality_curve). He hypothesized 20% of the employees were the most productive, 70% formed the base, and 10% weren't accretive to the business and should be released. There are clear costs to the Vitality System, but I won't debate them here.

When I read about a 10% reduction in staff in the press, I don't consider it an indicator of a startup's health. Instead, it's an acceleration of an end-of-the-year human resources practice to maximize cash. Layoffs that are materially larger than average attrition benchmarks are a different matter.
