Teamsters Say Amazon Workers at Riverside's DJT6 Began One-Day ULP Strike on Sept. 2

The International Brotherhood of Teamsters said workers at Amazon’s DJT6 facility in Riverside, California, began a one-day unfair-labor-practice strike Wednesday, escalating a yearlong fight over alleged retaliation and workplace safety. The account came from the union, and no Amazon response to the Sept. 2 action was available in the materials reviewed. The extent of any operational disruption also had not been independently verified.

The Teamsters said the strike began at 6 a.m. PT and involved workers affiliated with Teamsters Local 1932. In a news release, the union said employees on both primary shifts were participating and claimed the action would stop work at the site for 24 hours. That claim was not independently verified.

The union said the strike was intended to protest what it described as Amazon’s illegal conduct and retaliation against workers who had pushed for safer conditions on the job. A ULP strike is a strike that workers or a union say is in response to employer unfair labor practices. Whether that label is ultimately upheld can be contested, but it matters because workers in a ULP strike can have stronger legal protections than those in a purely economic strike.

DJT6 workers joined Local 1932 in December 2025, according to the Teamsters and prior local reporting. That same month, local outlets documented a walkout at the Riverside facility during the holiday peak, an early flashpoint in what has become a sustained organizing fight. In the Inland Empire, a logistics-heavy region where Amazon operates major warehouse and delivery hubs, labor fights at large fulfillment sites can draw broad local attention.

The union’s latest allegations build on earlier disputes over retaliation. KVCR reported on April 7, 2026, that workers rallied in support of DJT6 employee Andres Aguayo, whom co-workers said had been unjustly fired. Amazon did not respond in time for that April report, according to KVCR.

Wednesday’s strike also comes months after a March 31, 2026, labor settlement that was widely reported by the Teamsters and other outlets. Under that settlement, Amazon agreed to restore unpaid time off deducted from workers who took part in strikes and to stop making those deductions in retaliation for strike activity. At the time, Amazon said it did not admit wrongdoing.

In the Teamsters release, Randy Korgan, director of the Teamsters Amazon Division and secretary-treasurer of Local 1932, said, “Amazon thinks it can trample workers’ rights with no consequences, but Amazon Teamsters at DJT6 are proving them wrong.”

Amazon had not publicly responded to the Sept. 2 strike in the materials reviewed.
