American employers unexpectedly cut 92,000 jobs last month, a sign that the labor market remains under strain. The unemployment rate blipped up to 4.4%. The Labor Department reported Friday that hiring deteriorated from January, when companies, nonprofits and government agencies added 126,000 jobs. The job market had been expected to rebound this year from a lackluster 2025 when the economy, buffeted by President Donald Trump’s erratic tariff policies and the lingering effects of high interest rates, generated just 15,000 a month.
