Mack Trucks, Macungie announced April 17 an upcoming layoff of between 250 and 350 workers at its Macungie facility.

“I’m disappointed to hear of Mack Trucks’ decision to lay off workers after several quarters of weakening growth and despite being awarded hundreds of millions of taxpayer dollars under the previous administration,” U.S. Congressman Ryan Mackenzie, R-7th, said. “I’m particularly disappointed that they have opted to do so on the heels of last year’s decision to build new plants in Mexico instead of in our region. Lehigh Valley workers are among the best in the world, and I will continue to support policies that put American workers first and attract good paying jobs to our region.”

State Rep. Josh Siegel, D-22nd, released the following statement after the announcement in which he said the layoffs are “a devastating blow to Lehigh Valley workers and a clear signal of the dangerous economic instability being fueled by the Trump administration’s chaotic tariff policies.

“Once again, American workers are being sacrificed at the altar of political theater. The tariffs — erratic, broad and poorly targeted — are crushing core U.S. industries like trucking and manufacturing. Supply chains are snarled, costs are soaring and confidence among employers is collapsing.

“Communities like the Lehigh Valley, built on generations of hard work and industrial pride, are now being asked to carry the burden of this administration’s incompetence. These are good-paying union jobs that our community cannot afford to lose,” Siegel said.

“These 350 workers are not just numbers — they are parents, neighbors, veterans and skilled tradespeople who built America’s backbone. And they deserve better.

“It’s time for real leadership. I’m calling on Ryan Mackenzie who joined Mack UAW workers on strike during his congressional campaign and who has made a career of pretending to stand for workers despite consistently voting against them, to act — now. It’s urgent that Rep. Mackenzie along with Senators Fetterman and McCormack take back Congress’s constitutional authority on trade and end this economic sabotage before more livelihoods are lost. Standing by silently while working families suffer is unacceptable; they must protect Lehigh Valley workers.”
