How Illinois publishes its notices

The Illinois Department of Commerce and Economic Opportunity publishes the notices. Its file mixes WARN notices with other rows, and our list keeps only the rows the state marks as WARN notices.

Illinois prints an industry for every notice. Every 2026 notice also has a city and a worker count. The county cell is less tidy: the Bloomington notice from Ideal US Talent Systems reads "Not Applicable" there. One employer name appears in two spellings, Illinois Central School Bus, and we count its notices together.

Our read of the state's file is from November 10, 2026, one day after its newest notice, dated November 9, 2026.

The Illinois WARN list has every one of the 112, and the 4,897 notices around them.
