The Job Openings and Labor Turnover Survey, known as JOLTS, is published monthly by the Bureau of Labor Statistics. It measures job openings, new hires, voluntary quits, layoffs and discharges, and total separations across U.S. nonfarm establishments. JOLTS data is used by the Federal Reserve, economists, and policymakers to assess labor market tightness, worker bargaining power, and the pace of economic restructuring. The nine senators' March 6, 2026 letter specifically asked BLS to update JOLTS to include questions about whether hires, layoffs, and job postings are directly tied to AI adoption — a change that would allow real-time tracking of AI's role in labor market churn rather than waiting for the impacts to surface in aggregate employment data.
