Across the artificial intelligence (AI) supply chain, insiders describe a precarious, high-turnover workforce with limited support and stability.

This “invisible” human labor that labels data, evaluates outputs, and filters harmful material has become a revolving door of talent that navigates high-pressure gigs and burnout. Moreover, workers and industry experts say this talent churn can degrade the very AI models workers are paid to improve.

Across the board, workers who are hired to support, evaluate, or operationalize AI systems face similar challenges: high-stress environments that often involve complex tasks, unrealistic timelines, job instability, and low wages.

It’s no secret that the tech industry has long suffered from high turnover rates.Numbers vary, but many studies put the average rate of talent churn in the tech sector at between 13 percent and 18 percent.

This becomes clear when considering the cost of replacing tech talent, which can be up to 150 percent of a worker’s salary, including recruitment expenses, onboarding time, productivity losses, and impacts on customer relationships.

Some believe that the loss of institutional knowledge alone makes worker retention critical.

“People love to talk about the ‘magic’ of AI, but the work culture behind it is a meat grinder.I’ve seen talent turnover in model evaluation hit record highs because the work is repetitive and psychologically draining,” Barry Kunst, vice president of marketing at Solix Technologies, told The Epoch Times.

“When you lose a lead researcher to churn, you don’t just lose a body; you lose the ‘why’ behind the model’s safety guardrails,”Kunst said.

This is why he’s adamant about AI workforce stability, which he said correlates directly with model reliability: “If you’re rotating contractors every six months to keep labor costs low, your data governance will fail, period.”
