On Wednesday, April 10, Amazon Flex drivers rallied outside of a delivery station in Woodland Park, New Jersey. Holding a banner reading “CONTRA LOS ABUSOS DE AMAZON,” the workers demanded Amazon commit to lower delivery quotas that prioritize safety as well as raising base pay for the workforce. The morning gathering followed a petition drive by the workers demanding such commitments from Amazon: more than three hundred drivers have signed.

Amazon launched Flex in 2015 to fulfill the demands of Prime Now, which promises customers same-day delivery, often within a matter of hours. Most Amazon customers are used to receiving packages from drivers in Amazon-branded vans, employees of the hundreds of delivery service partners (DSPs) that exist to service Amazon.

But Flex drivers work out of their own unmarked personal vehicles. They’re classified as independent contractors, even though the conditions of their work are determined by Amazon, which requires they complete unpaid training — watching lots of videos about how to interact with customers and deliver packages — before being accepted on the Flex app. As such, they shoulder all the costs of that labor, paying for the gas, tolls, and vehicle wear and tear that come with it, without benefits like health insurance and workers’ comp or even guaranteed hours, and they’re exempt from minimum wage protections and overtime pay too — and they also take on serious risks.
