BALTIMORE, (Reuters) – The United States will closely monitor Monday’s vote at Mexico’s Tridonex auto part plant union election, U.S. Trade Representative Katherine Tai said to reporters. She stated that the United States has an “outsized” interest in this matter.

After an event held at Morgan State University, Tai stated that “We’re monitoring that vote extremely closely.” We clearly have an overwhelming interest in what happens given the agreement we had with the company regarding their participation in future election.

After two years’ of labor organizing by workers at Tridonex, nearly 1,700 Tridonex workers are set to vote Monday for their union representation. This is after some workers tried to replace the union they claimed was failing to promote higher wages.

Tridonex agreed in August to guarantee worker rights, pay separance and back wages for dismissed workers to settle a labor rights complaint under the United States-Mexico Canada Agreement (USMCA).

AFL-CIO had made a formal complaint to the USTR following Tridonex worker claims that they were denied the freedom of choice in their representation.

Monday’s vote gives workers in Matamoros a choice between the Confederation of Mexican Workers or SNITIS, an independent organization.

Cardone, an Auro parts manufacturer based out of Philadelphia, said that it would be neutral and will work with workers.
