Illinois WARN: 60 days notice for plant closings — stricter than federal.
The Illinois Worker Adjustment and Retraining Notification Act (820 ILCS 65) is stricter than federal WARN: it covers employers with 75 or more full-time employees (federal is 100+) and requires 60 days advance written notice for plant closings or mass layoffs meeting the statutory thresholds. The Illinois Department of Labor enforces. Penalty for non-compliance: back wages plus benefits up to 60 days, plus civil penalties.
Illinois WARN Compliance Tracking
Tracks employer coverage at the 75-employee threshold. Identifies events that trigger notice requirements. Surfaces 60-day countdown when triggers approach.
What those rules do when bulk-termination workflows initiate.
The hero card configuration: Critical on notice surfacing, Block on bulk-termination without notice.
When an Illinois employer with 75+ employees initiates a workflow that meets WARN trigger criteria (plant closing 25+ workers, mass layoff 25+ workers if 33%+ of workforce, or 250+ regardless), Teambridge surfaces a Critical indicator with the 60-day countdown.
If a bulk-termination workflow attempts to execute without 60 days of notice on file (or a documented exemption), the workflow is blocked. The block protects against accidental WARN violations.

Stricter than federal — and the threshold gap matters.
Illinois WARN is one of the few state WARN-equivalents that's stricter than federal. The 75-employee coverage threshold pulls in employers federal WARN doesn't reach, and the IL DOL has been an active enforcer.
Coverage threshold — stricter than federal
Illinois WARN covers employers with 75+ full-time employees in Illinois. Federal WARN covers employers with 100+. So an employer with 75-99 IL employees is covered by IL WARN but not federal — and could violate Illinois law without violating federal. Multi-state employers must track each state's threshold separately.
Trigger events: closings and mass layoffs
Plant closing: shutdown of a single site causing employment loss for 25+ full-time employees in any 30-day period (or 90 days aggregated). Mass layoff: employment loss at a single site of 25+ full-time employees representing 33%+ of the workforce, OR 250+ regardless of percentage. The 25+ mass-layoff trigger is stricter than federal (federal requires 50+).
Teambridge tracks coverage at 75+ and surfaces triggers as bulk-termination workflows initiate.
WARN Act compliance is mostly about NOT missing the trigger conditions. Most violations come from employers who didn't realize a workflow met WARN criteria.
75-employee mark monitored.
Teambridge continuously tracks IL employee count. When the headcount reaches or exceeds 75, IL WARN coverage activates. Employers approaching the threshold see advance notice.
Bulk-termination workflows analyzed.
When a workflow involves termination of multiple workers, Teambridge analyzes whether the cumulative effect crosses WARN thresholds (25+ at a single site, 33% of workforce, or 250+ regardless). 90-day aggregation windows are tracked.
Notice timing surfaced visibly.
When a WARN-triggering event is identified, the workflow shows the 60-day notice deadline. Operators can either delay execution or document an exemption.
Recipients confirmed before execution.
Teambridge tracks whether notice has been issued to all required recipients (employees, IDOL, IDCEO, local elected official). Without confirmation, bulk-termination execution is blocked.
