Since last week, nearly 50,000 GM workers have been on strike, in part against a two-tiered system enforced by the auto giant that leaves “temporary” workers doing the same jobs as permanent staff for substantially less pay and fewer benefits. The striking workers, represented by the United Automobile Workers union, or UAW, are demanding a defined path to “permanent seniority” for GM’s temporary workers — who make up about 7 percent of GM’s U.S. workforce. GM has also entrenched inequality in its ranks by contracting out some jobs, like custodial work, that were traditionally staff roles. “I work right across from a temporary employee who’s been there for two and a half years,” Chaz Akers, a Michigan-based autoworker who has worked at GM for 3 1/2 years told Reuters. “I install the passenger side headlight. He installs the driver side headlight. I make more money than he does. I have better health insurance than he does. It ain’t fair. It ain’t right. If you’re going to pay people to do a job, pay them all the same.” The workers’ demands are part of a broader push against worker misclassification, a tactic used by employers to lessen their labor costs. The fight has been playing out most aggressively in California, where Democratic Gov. Gavin Newsom signed a sweeping bill last week to transform the lives of workers in his state. The law — known as AB5 — sets strict limits on who can be classified as an independent contractor, rather than an employee, and is the most serious legislative threat to the gig economy in years. The law also provides new momentum for advocates considering similar reforms in other states. Coming to an agreement on temporary workers has become the most difficult issue in the GM-UAW negotiations, according to the Detroit Free Press. Both sides are reportedly holding strong to their positions. The Free Press also reported that resolving questions around temp workers was union members’ top request when UAW leadership surveyed them last year.

Protests of temporary workers by the UAW is “not a brand-new development” said Jake Rosenfeld, a sociologist at Washington University in St. Louis and author of “What Unions No Longer Do.” “But it does seem really foregrounded now in the union’s complaints, and that seems new. These classification disputes, from my perspective, seem to be growing and tracks on to the same battles over classification in California with Uber and Lyft.” GM, like Uber and Lyft, is pushing back against the workers’ demands by claiming that such “flexible” workers are necessary for its business model. Right now, GM is trying to convince permanent, full-time workers to accept raises and more job security in exchange for freedoms around temps. For example, GM has reportedly proposed a boost to the company’s profit-sharing formula, financial gains that would only go to permanent, full-time employees. GM workers typically earn about $1,000 for every billion in GM’s North American pretax profits. In 2018, eligible employees earned payments up to $10,750.

Temporary workers, who often do the same work as traditional employees, are paid less, entitled to fewer benefits, and are easier to get rid of. “That’s a trend that we’re seeing all over the economy as companies try to shed conventional, full-time employees in favor of independent contractors, subcontracted workers, or franchised employees,” said Alexander Hertel-Fernandez, a political scientist at Columbia’s School of International and Public Affairs. “The difference with the auto manufacturers is that their temporary workers are covered by the UAW and its contracts, unlike in most other sectors of the economy.” In 2007, under pressure from the financial crisis, UAW leaders agreed to a two-tiered contract, in which new GM hires would be paid at lower rates than workers hired before. To get out of this arrangement, widely deemed unfair, the union negotiated a new contract in 2015, in which new hires would still have lower starting salaries, at $15 an hour, but could “grow into” the full UAW hourly wage of roughly $30 an hour after eight years. Union leaders — citing GM’s clear improved financial position with billions of dollars in profit — now want to shorten that process, under the basic principle of equal pay for equal work. GM and the UAW did not return requests for comment.
