Revelio Labs' Evan Sohn joins CNBC's The Exchange to discuss November JOLTS data and a labor market that is largely frozen, with low hiring, firing, and quitting. He notes salaries are ticking down and workers feel trapped because they are comfortable with current pay, while job postings are down overall. His data shows 71,000 jobs added last month, the first hiring increase in a while, but only information technology and biotech/health support saw year-over-year growth. He also highlights that over 40% of job postings now mention AI, underscoring the tech transformation in labor demand.
