The American auto industry is facing a fresh wave of layoffs, and the consequences extend well beyond the gates of Mack Trucks, Volvo, and Stellantis.

Mack Trucks has announced plans to cut up to 350 positions at its Lehigh Valley Operations Center in Lower Macungie Township, Pennsylvania. Volvo Trucks is eliminating another 450 jobs across its facilities in Dublin, Virginia, and Hagerstown, Maryland. Stellantis has confirmed the temporary layoff of 900 employees at its plants in Michigan and Indiana. In total, 1,700 direct jobs are being lost.

At first glance, that number may sound manageable in the context of the national economy. But when it comes to the auto industry, what happens on the assembly line doesn’t stay on the assembly line.

Transportation Equipment Manufacturing: A Pillar of the U.S. Economy

Transportation Equipment Manufacturing is a heavyweight in the U.S. economy. It contributes more than 1% of GDP and accounts for 2.5% of total output. One out of every 126 working Americans is directly employed in the industry. It’s an industry built on robust supply chains, skilled labor, and widespread consumer demand.

That scale means disruptions don’t happen in isolation—they cascade.

1,700 Jobs Lost, 11,500 Jobs Impacted

According to a recent IMPLAN analysis, the 1,700 direct job losses at Mack, Volvo, and Stellantis will ultimately lead to the loss of approximately 11,500 jobs across the country. That’s because each direct job in the Transportation Equipment Manufacturing sector supports roughly 5.75 additional jobs in the supply chain and in consumer-facing industries like healthcare, housing, retail, and entertainment.

“The impact of recent layoffs at Mack Truck, Volvo, and Stellantis goes far beyond the factory floor,” said Candi Clouse, Ph.D., Senior Economist at IMPLAN. “While 1,700 direct jobs are being lost, the ripple effect through supply chains and local economies means we’re actually looking at over 11,500 jobs lost nationwide. That’s one job lost, triggering nearly six more. These cuts don’t just affect paychecks—they’re expected to reduce U.S. GDP by $1.8 billion and cost over $362 million in tax revenue across local, state, and federal levels. Transportation equipment manufacturing is a cornerstone of the American economy, and when it suffers, entire communities feel the impact.”

GDP and Tax Revenue Losses Add to the Toll

Those direct jobs supported approximately $438 million in GDP. When the full economic impact is taken into account, the expected loss to the nation’s GDP climbs to $1.8 billion.

And the fiscal consequences don’t stop there. These job losses are projected to yield a combined $362 million loss in tax revenue—impacting everything from local public services to federal programs.

Local Communities, National Stakes

Layoffs like these bring stress and uncertainty to affected workers and their families. But their impact also ripples into local businesses, schools, healthcare systems, and housing markets.

Communities in Pennsylvania, Virginia, Maryland, Michigan, and Indiana will feel the most immediate impact, but the economic shockwaves will be felt nationwide. That's the reality of an industry so deeply woven into the fabric of the U.S. economy.

In a time of heightened global competition and tariff uncertainty, these developments highlight the importance of understanding not just the direct consequences of industry changes, but the far-reaching ripple effects as well.
