Amazon Flex drivers, who deliver packages for the e-commerce giant have long suspected that the company surveils their private Facebook groups, where workers share frustrations, advice, and jokes about their work—and sometimes, criticize the company for their working conditions. 

On Tuesday, Motherboard published internal documents, reports, and an online tool confirming their suspicions. The files show that for years Amazon has meticulously tracked Amazon Flex drivers in dozens of closed Facebook groups across the United States, the United Kingdom, and Spain. Amazon corporate employees receive regular reports detailing the posts of its gig workers on Facebook, according to the files left online and viewed by Motherboard. Among other concerns, the tool monitors "planning for any strike or protest against Amazon."
