A Senate HELP Committee investigation led by Sen. Bernie Sanders found that Amazon deliberately manipulated worker injury data and suppressed internal safety research. Amazon workers were nearly twice as likely to be injured compared to other warehouse workers. Internal 'Project Soteria' found a direct connection between speed quotas and injuries, but Amazon refused to implement its recommendations. Amazon's in-house AmCare clinics purposely discouraged workers from seeking outside medical care to avoid OSHA reporting. Workers suffered chronic pain, disabilities, and diminished quality of life.
