California WARN Notices - Mass Layoffs & Plant Closures

California has 2,995 WARN Act notices on file, affecting 174,753 employees. The most affected city is San Diego with 3,859 employees affected.

California has its own Cal-WARN Act, which applies to employers with 75 or more employees — a lower threshold than the federal requirement of 100. California requires the same 60-day advance notice for plant closures, mass layoffs, and relocations. California's Employment Development Department (EDD) maintains the official state WARN Act notice list.
