A new report by Reveal from The Center for Investigative Reporting claims that Amazon, valued at about $160 billion, habitually ignored injury reporting and safety regulations for years up until 2015, and that its policies have resulted in injuries to many of its employees to date.

According to the report, “the company’s obsession with speed has turned its warehouses into injury mills.”

In fact, according to internal injury records from 23 Amazon fulfillment centers across the US, the “rate of serious injuries for those facilities [in 2018] was more than double the national average for the warehousing industry,” the report explains. There were 9.6 serious injuries for every 100 full-time workers at the selected Amazon centers last year. The industry average was 4 per 100 workers.
