Note: Illinois figures come from the state's live WARN dashboard; no October 2026 monthly report is published yet. Multi-notification filings are counted once at their live breakdown: Panduit's and Dana's earlier tranches were revised to zero, so only their future layoffs are listed. T-Mobile's cumulative 342 workers are excluded because every layoff in its breakdown falls before September 1, 2026. INEOS Joliet is not listed separately — its October 2 notification matches the INEOS Channahon row already on this page.
