Delivery routes, where drivers are expected to drop off between 250 to 400 packages, typically run 10 hours.

But when Ervin allowed drivers to end their shifts without completing their Amazon’s delivery routes last year over what he said were health concerns, Amazon threatened to put Ervin on official notice that he could lose his contract, he said.

While the Teamsters ・ with 340,000 represented UPS employees ・have been trying to unionize Amazon drivers for years, their commitment to that effort was redoubled when Sean O’Brien, the current progressive union president, won a hotly contested race in 2021. O’Brien campaigned on a platform that was critical of past Teamsters leadership for not taking a more aggressive approach to organizing Amazon’s growing logistics empire.

With their UPS contract expiring this August, O’Brien and the Teamsters are already gearing up for a potential strike.

The pandemic resulted in an uptick of labor activism at Amazon, which is the nation’s second-largest private employer. In a first, Amazon warehouse workers in Bessemer, Ala. voted in 2021 on whether to unionize their warehouse, but the results were thrown out by a judge. The results of a second election held a year ago are stuck in litigation.

Around the same time last year, the upstart Amazon Labor Union made history when it won a union election in Staten Island, the first of its kind inside Amazon. That vote is also being challenged by Amazon, which is locked in a legal battle to get the union’s victory thrown out.
