While the total injury rate amongst Amazon warehouse workers has declined from 2021 to 2022, the overall injury rates are still higher than pre-pandemic levels. Additionally, injuries are more common at Amazon compared to its other competitors, which has been blamed on the fast pace of the Amazon warehouses; and the company accounts for more than half of all serious injuries in the warehouse industry, while only employing a third of workers. Despite Amazon's claims that it is working to address these workplace safety concerns, OSHA has recently begun inspections into various Amazon warehouses.
