UAW Strikes American Axle in Michigan, Threatening GM Pickup Production

About 1,000 workers represented by the United Auto Workers walked off the job at American Axle's plant in Three Rivers, Michigan, shortly after midnight Monday, after the union and the company failed to reach a new contract by their deadline.

Members of UAW Local 2093 took to the picket line outside the factory. The union categorized the walkout as an unfair-labor-practice strike, citing several unfair-labor-practice charges it had previously filed against the company.

The stoppage threatens to slow or halt production of General Motors pickup trucks within weeks, because the plant supplies driveline components used in those vehicles.

What the workers are asking for

Workers at the plant authorized a strike in May if the company failed to meet their demands. According to the union, those demands include:

• Higher wages
• Profit sharing
• Better healthcare
• Stronger retirement terms
• Better job protections

An unfair-labor-practice strike is legally distinct from an economic strike: the union is asserting that the employer committed labor-law violations during bargaining, which can affect workers' reinstatement rights and the legal posture of the dispute.

Why a supplier strike hits the automaker

American Axle is a Tier 1 supplier — it builds components that feed directly into an automaker's assembly line. A relatively small workforce at a single supplier plant can bring a much larger downstream operation to a stop, because modern auto production runs on just-in-time inventory with little slack.

That leverage is the point. It is also why supplier disputes can escalate quickly into pressure on the automaker to help broker a settlement.

What we're watching

• Whether GM truck plants that depend on the components begin to idle, and how fast
• Whether the unfair-labor-practice charges advance at the National Labor Relations Board
• Whether the parties return to the table or dig in
