New union at GM Mexico plant could benefit US autoworkers

Workers at a General Motors plant in Silao, Mexico, will vote in February to select one of four unions to represent them.

It may be too soon to know if car buyers will see a boost in prices for full-size pickups after workers at a General Motors plant in Mexico voted to form the first independent labor union earlier this week but U.S. autoworkers are cheering the move, saying it makes them more competitive with that nation’s workforce.

The union, called the National Independent Union of Workers of the Automotive Industry (SINTTIA), won the vote by a wide margin to represent about 6,500 workers in upcoming labor negotiations at GM’s Silao Assembly plant, located about 200 miles north of Mexico City. Both wages and benefits are expected to increase under the union.

GM builds the highly-profitable Chevrolet Silverado and GMC Sierra light duty full-size pickups at Silao. In the current plant contract, it said the wages range from 184.35 pesos to a maximum of 679.53 pesos per day. In dollars, that’s about $8.97 to $33.05 per day. In contrast, GM builds the same light-duty pickups at Fort Wayne Assembly in Indiana and will start building the light-duty Silverado at Oshawa Assembly in Ontario soon. GM builds its heavy-duty pickups at Flint Assembly and Oshawa. At those plants, wages range from $18 to $32 an hour.

The 2022 Chevy Silverado starts at $31,500 and climbs to more than $65,000 depending on the model; the GMC Sierra starts at $30,800 and increases to more than $78,000, according to Kelley Blue Book. 

An article in the New York Times reports the pay for starting workers at GM’s Silao plant is lower than the pay “at some Nissan, Audi and Volkswagen plants in Mexico that are represented by independent unions, and just 60 cents above the country’s daily minimum wage.” 

UAW members view higher wages in Mexico as good news for both the workers in Mexico and stateside. It brings production costs on par to U.S. factories, potentially giving U.S. workers an edge at winning future products to build.

“Their wages go up, that helps us,” said Eric Welter, UAW Local 598 shop chairman at Flint Assembly. “I don’t know what initial benefit there’ll be, but it makes us more competitive and helps us not to have to make future sacrifices. We’re on a more level playing field in the future.”
