What this means for IN workers
ArcelorMittal has 1 WARN filing on record covering 978 workers, most recently on May 12, 2009.
WARN Act filings only capture layoffs of 50+ workers at sites of 100+ employees, so smaller reductions, contractor non-renewals, and voluntary separations are not shown here.
Federal WARN Act filings place ArcelorMittal on record with 1 notice covering 978 workers, spanning May 12, 2009 through May 12, 2009. Because the WARN Act only captures events that affect 50 or more workers at sites of 100+ employees, this count sits at the upper band of the employer's layoff activity — smaller reductions, contractor non-renewals, and voluntary separations are invisible to this dataset. The geographic footprint of 1 state, anchored in IN, in the Manufacturing sector, shapes which state workforce agencies received the filings and which state-level "mini-WARN" thresholds applied.
Averaging 978 workers per notice, ArcelorMittal's filings fall into a pattern that resembles full-facility closures or company-wide restructuring — events that can reshape local labor markets for years. This single notice marks a discrete restructuring event rather than a sustained pattern, though workforce changes below the 50-worker WARN floor may have occurred without disclosure.
For workers, the practical layer under these numbers is time: the WARN Act's 60-day notification window triggers eligibility for state unemployment insurance, COBRA health-coverage continuation, and rapid-response services from the state workforce agency that received the filing. Workers on IN-based ArcelorMittal notices should contact the IN workforce agency directly — response teams, severance negotiation guidance, and TAA (Trade Adjustment Assistance) screening move fastest in the days immediately following a notice. The record above reflects filed notices only; subsequent hiring, rescinded closures, or facility reopenings are not tracked by WARN disclosures.
ArcelorMittal has one WARN Act filing on record. A single notice may reflect an isolated restructuring event, facility closure, or response to changing market conditions.
With an average of 978 workers per notice, these are large-scale events that can significantly impact local economies and labor markets. WARN Act notices only capture layoffs meeting federal thresholds (50+ workers) and may not represent all workforce changes.
ArcelorMittal has filed 1 WARN Act notice affecting 978 workers across 1 state. The most recent notice was filed on May 12, 2009.
According to WARN Act filings, ArcelorMittal has affected 978 workers total, averaging 978 workers per notice.
ArcelorMittal has filed WARN notices in 1 state: IN.
The Worker Adjustment and Retraining Notification (WARN) Act requires employers with 100+ employees to provide 60 days advance notice of plant closings and mass layoffs affecting 50 or more workers. Not all layoffs require WARN notice.
Workers affected by a WARN-notified layoff may be eligible for unemployment insurance, COBRA health coverage continuation, job retraining through the Trade Adjustment Assistance program, and severance packages if offered by the employer. State workforce agencies often provide additional rapid response services.
ArcelorMittal has affected 978 workers across 1 WARN filing in the Manufacturing sector. The federal WARN Act only captures layoffs affecting 50 or more workers, so actual workforce changes may be larger.
