INEOS is preparing another round of layoffs at its Joliet-area chemical complex in Channahon, according to Crain's Chicago Business. The move continues a start-and-stop pattern at the site and could ripple through Will County’s workforce and supplier network.
Crain’s reports the company has floated plans for additional staff cuts, but details about how many positions and when they’d be eliminated haven’t been made public. The Crain’s item is the first public account of the latest plan and, in its public version, doesn’t include a full company statement.
What the Joliet site makes and how big it is
INEOS’s Joliet complex is a major chemical-intermediates operation producing Purified Isophthalic Acid (PIA), Trimellitic Anhydride (TMA), and Maleic Anhydride (MAN) — feedstocks used in coatings, resins, and plastics — according to INEOS Joliet. The company describes the plant as roughly 775 acres with integrated utilities and wastewater treatment capacity — a footprint where any labor disruption can affect multiple product lines and nearby suppliers.
Earlier shutdown and job cuts
The Joliet site has seen turbulence recently: In April 2024, a line that made a curing agent for epoxy and related products was idled, and 49 workers were laid off, an action reflected in public layoff records. WARNTracker.
What workers and local officials can expect
Under Illinois law, employers meeting the threshold must provide 60 days' notice for plant closings or mass layoffs, and state agencies coordinate rapid-response services for affected workers and towns. The Illinois Department of Commerce and Economic Opportunity maintains WARN reporting and layoff resources that local officials and employees can consult as any new notices are filed. Illinois DCEO.
For now, Crain’s reporting is the main public signal. More concrete details are likely to show up in formal WARN filings or an official company release. We’ll watch for those documents to clarify the scale and timing of the reductions and what support will be offered to affected workers.
