Sixty Proterra employees from its City of Industry, Calif. manufacturing location joined the United Steelworkers (USW).

After an overwhelming majority of workers requested representation, Proterra management voluntarily recognized the union on Nov. 12. USW International President Thomas M. Conway congratulated the union’s newest members and praised Proterra management for its conduct throughout the organizing process.

“U.S. manufacturing and manufacturing workers are vital to the innovation and economic future of this country,” Conway said. “It’s important that we capitalize on the technological advancements and strengths of American companies to seize the tremendous momentum happening in the domestic electric vehicle sector and promote American leadership in this next transportation revolution.”

Conway added it is imperative that the development and production of clean technology promote good jobs and healthy communities in the U.S., including ensuring the materials and components in the transportation supply chain are made in America and that the workers who make them earn fair wages and good benefits.

“There is an unprecedented opportunity to solve some of the greatest challenges facing us today while creating and preserving quality American manufacturing jobs,” said Proterra CEO Ryan Popple. “Proterra and the United Steelworkers share a common vision to support American workers while building a healthier and more resilient future for all, and we look forward to a strong partnership.”
