Illinois runs its own WARN Act — and it catches more layoffs than federal law alone would. Under 820 ILCS 65, Illinois requires employers with 75 or more employees to give 60 days' notice before a mass layoff or plant closure. That lower threshold means more filings, more visibility, and more candidates that federal-only monitoring would miss entirely.
In 2026, TalentWire tracks 392+ Illinois WARN filings covering 22,000+ displaced workers. Here's what staffing agencies need to know to turn that data into placements.
Illinois State WARN Act: 820 ILCS 65
Illinois passed its own plant closing law that applies alongside the federal WARN Act. Key differences from the federal standard:
- Employee threshold — Illinois covers employers with 75 or more employees, compared to the federal 100-employee minimum. This captures a significant layer of mid-market employers that federal WARN misses.
- Notice period — 60 days advance notice, matching the federal standard.
- Layoff trigger — A mass layoff affecting 25 or more workers, or a plant closing resulting in any job losses at a single site.
- Filing recipient — Notices go to the Illinois Department of Commerce and Economic Opportunity (DCEO), the chief elected official of the affected municipality, and the state dislocated worker unit.
The 75-employee threshold is the key differentiator. A company with 80 employees has to file in Illinois. The same company is invisible under federal WARN. For staffing agencies, that means a substantial pool of candidates — particularly from mid-market manufacturing and professional services firms — that shows up in Illinois data and nowhere else.
Illinois 2026 WARN Filings: By the Numbers
With 392+ filings and 22,000+ workers displaced in 2026, Illinois is one of the highest-volume WARN states in the country. Several factors drive that volume:
- The 75-employee threshold captures a wide mid-market employer base
- Illinois has a concentrated manufacturing base, particularly in the Chicago metro and downstate industrial corridors
- Healthcare system consolidation continues to generate filings from hospital networks and long-term care facilities
- Professional services firms in Chicago — legal, consulting, financial — file when economic conditions shift
For context: states using pure federal standards generate roughly one filing per 100-employee-plus employer. Illinois' lower threshold means a materially larger filing universe — giving staffing agencies earlier and wider visibility into workforce displacement events.
Key Industries: Where Illinois WARN Filings Concentrate
Manufacturing
Illinois has one of the largest manufacturing employment bases in the Midwest. WARN filings from manufacturing cover assembly workers, CNC operators, quality technicians, warehouse and logistics coordinators, and plant managers. These workers have specialized skills in specific equipment and processes — and their separation windows are often short, making speed of outreach a competitive advantage.
Healthcare
Hospital system consolidation, long-term care facility closures, and behavioral health organization restructurings generate consistent WARN filing volume in Illinois. Healthcare filings surface registered nurses, medical assistants, allied health professionals, and administrative staff — roles in high demand across competing health systems.
Professional Services
Chicago is a major hub for legal, consulting, accounting, and financial services. When these firms downsize — whether through practice group eliminations or firm mergers — Illinois WARN filings capture the displacement. These candidates typically have strong professional credentials and place quickly into similar roles, making early outreach especially valuable.
Why the 75-Employee Threshold Creates a Sourcing Edge
The federal 100-employee threshold is well-known. Most national job boards and aggregators that monitor WARN data are set up around federal filings. Illinois' 75-employee threshold creates a gap: a meaningful segment of layoffs that appear in Illinois state data but get zero coverage from federal monitoring tools.
For staffing agencies focused on Illinois placements, this gap is an advantage. You can access candidates from layoffs that your competitors aren't tracking — if you're monitoring state filings directly or using a platform like TalentWire that aggregates state-level WARN data alongside federal.
How to Work Illinois WARN Filings
- Monitor DCEO filings weekly — Illinois publishes WARN notices through the Department of Commerce and Economic Opportunity. Volume spikes in Q1 (post-budget) and Q3 (mid-year adjustments).
- Calculate the 60-day separation window — Mark the effective layoff date from the filing. Build outreach in three phases: immediate contact, 30-day follow-up, and 55-day final check-in before separation.
- Segment by industry and location — Chicago metro vs. downstate Illinois filings represent very different candidate profiles and local market conditions. Don't treat all Illinois filings as a single pool.
- Cross-reference with LinkedIn and WARN contact data — Illinois filings include an HR or WARN coordinator contact. That contact is managing outplacement for the full affected workforce — building that relationship gives you systematic pipeline access.
- Track repeat filers — Some Illinois employers file multiple WARN notices across a restructuring cycle. A second or third filing from the same employer signals a deeper reorganization — and a larger candidate pool than any single notice shows.
