WARN notices are typically required when companies with 100 or more employees plan a mass layoff or plant closing affecting at least 50 workers. Because WARN notices are often filed weeks before layoffs take effect, they can provide an early indication of workforce reductions to come. The layoff filings range from one worker to dozens per site, with a San Bruno filing affecting 88 employees and several Sunnyvale notices affecting between 49 and 68 workers. "The good news is the labor market has proven to be largely resilient over the last year, but the sectors seeing employment gains are increasingly uneven.” "These layoffs do not yet signal a collapsing labor market, but they do suggest it is becoming a ‘low-hire, low-fire’ economy."
