General Mills is pulling the plug on its St. Charles pizza crust plant in early June, a shutdown that will wipe out 163 jobs in St. Charles County. According to a federal WARN notice tied to the move, all layoffs are expected to be wrapped up within 14 days of June 8, and the closure is labeled permanent.
As First Alert 4 reports, the Worker Adjustment and Retraining Notification identifies the facility at 3850 Millstone Parkway and makes one point painfully clear: employees losing their jobs are not eligible to transfer or bump workers at other locations. The notice lays out both the timing and the headcount tied to the shutdown.
What company filings show
General Mills first put the Missouri closures on the record in a Sept. 25, 2025 filing with the Securities and Exchange Commission, describing them as part of a multi-year effort to streamline its supply chain. The company’s 8-K states that the actions, which include shutting down the St. Charles pizza crust site and two pet food plants in Joplin, were approved to consolidate capacity and could result in roughly $82 million in restructuring charges. The filing also spells out near-term asset write-offs and estimated severance costs tied to the plan.
Local leaders, next steps
Local officials are already trying to cushion the blow for workers. Rep. Travis Wilson’s office says it is coordinating with the St. Charles County Department of Workforce & Business Development and the Economic Development Council to connect affected employees with job services and other resources, according to a press release. The Missouri House of Representatives release also lists local workforce contacts and notes that leaders are working to recruit a new manufacturer for the site.
The St. Charles closure tracks with the broader consolidation plan General Mills rolled out last fall. At that time, local coverage noted the company expected its Missouri actions to wrap up by mid-2026 and reported that some Joplin workers would be offered roles at other locations. Missourinet covered that earlier disclosure and the company’s restructuring estimates.
For now, the WARN notice has started the countdown to early June, and county workforce officials remain the go-to source for details on severance, benefits and reemployment programs. St. Charles County and the congressional offices named in the official notices are expected to publish more guidance for employees in the coming days as the shutdown date approaches.
