The International Association of Machinists and Aerospace Workers (IAM Union) participated in a recent briefing with labor experts and Congressional allies to highlight labor priorities during the review of the U.S.-Mexico-Canada Agreement (USMCA). The session aimed to inform Congressional staff about the need for reforms that prioritize workers. Although USMCA has made improvements over its predecessor, NAFTA, speakers at the event expressed concerns about ongoing wage disparities, weak enforcement measures, and increased foreign exploitation that could threaten jobs in the United States.
During the briefing, participants emphasized several key areas for reform. These included strengthening Rules of Origin to discourage offshoring, closing loopholes that permit Chinese goods to be transshipped or assembled in Mexico before entering the U.S., expanding labor enforcement tools such as the Rapid Response Mechanism, addressing wage differences that encourage companies to relocate jobs abroad, and protecting critical manufacturing sectors like aerospace, automotive, steel, and aluminum.
A significant part of the discussion centered on risks facing the aerospace sector. Peter Greenberg, IAM Union International Affairs Director, warned that immediate action is necessary to prevent job losses in this industry. He explained how closely linked aerospace manufacturing is between the U.S. and Canada and described its vulnerability.
“One of our great fears has been an interruption of the aerospace supply chain, particularly because it is very closely tied between the U.S. and Canada,” said Greenberg.
Greenberg also pointed out concerns regarding China’s use of Mexico as a way station for goods entering the United States without tariffs.
“China is using Mexico as a transshipment location,” Greenberg continued. “It allows goods to be repackaged and essentially enter the United States tariff-free.”
He added that Mexico could become a final assembly site for Chinese aerospace products—a development he argued would put jobs related to Boeing, Airbus, and American jet engine production at risk. Greenberg referenced China’s growing presence in commercial aviation through initiatives like COMAC C919 and noted efforts by China’s Belt and Road financing strategy to challenge North American manufacturers.
Other speakers at the event included U.S. Representative Linda Sánchez (D-Calif.), Ranking Member of the House Ways and Means Trade Subcommittee; Riley Ohlson from AFL-CIO; Roy Houseman from United Steelworkers; and Christopher Zatratz from United Auto Workers.
