Unionized workers at a Michigan plant that makes axles for General Motors trucks walked off the job on June 1 after a 10‑day strike. The strike halted production of key components for the Chevrolet Silverado and GMC Sierra, putting a strain on GM’s heavy‑duty pickup supply chain for customers in Texas and Ohio states today ahead.

Negotiations culminated in a tentative agreement between the UAW and Dauch Corp., formerly American Axle. The deal, still pending a vote by the plant’s roughly 970 hourly workers, could restore full operations at the Three Rivers, Mich., facility. Workers say the contract will recover a significant portion of lost wages and benefits for future jobs.

The settlement lifts a 10‑day interruption that cost GM an estimated $10 million in lost output and dented dealer confidence. It also signals a broader trend of union pressure reshaping supplier relationships in the automotive sector. For investors, a return to steady axle production supports GM’s pickup sales targets for the fiscal year in 2025 quarter.

The agreement must still be ratified, and its approval is not guaranteed. If rejected, the plant could resume striking, further disrupting GM’s supply chain and potentially forcing the automaker to source alternative axle suppliers. Until the vote concludes, stakeholders watch closely as the outcome could redefine labor dynamics across the truck manufacturing industry for 2026.
