The union has already idled production lines at three plants in response to failed negotiations with Ford, GM and Stellantis. As the UAW threatens further work stoppages, supplier health may be at risk.
“Depending on how deep this strike goes, it can be really challenging for the suppliers to stay afloat. Risk is particularly focused on the Tier 2 and Tier 3 suppliers,” said one industry expert. He added: “Tier 1 firms should be talking to downstream suppliers, asking: ‘How are your financials? When we do get out of this, are you going to be able to ramp back up?’”
To be proactive, supply chain managers can streamline various processes which include order intakes, raw material and labor planning.
Order cancellations from the affected assembly plants can bottleneck the entire supply chain. Suppliers can continue to build parts regardless of canceled orders, but if the customer refuses to accept deliveries, then suppliers need to pay to store those parts. Demand for the parts and materials will decrease or even cease as the automakers cancel firm orders for parts and future orders in the coming weeks and even months, depending on the duration of the strike.
As a result, the supply chain will likely feel lingering impacts even when the strike eventually ends. For instance, suppliers who may have furloughed workers might take a while to get operations up and running. If more automaker plants get impacted, downstream suppliers may need to reboot their systems.
Ripple effects will move across the entire supply chain. Tier 1 suppliers with strong balance sheets will be fine. But Tier 2 and Tier 3 suppliers may struggle with cash flow as orders are canceled. Secondary effects are already being seen. GM is temporarily laying off employees at its Fairfax plant — which is not included in the first wave of strikes — as that facility’s operations are disrupted from a lack of stamping parts from the Wentzville facility, which is on strike. While supply chain managers may be able to keep things moving, operations get tricky if the UAW goes after engine plants. Shutting down plants where engines are built will cripple other plants across the U.S., Canada and Mexico.
