Occupational Safety and Health Administration (OSHA) inspectors found workers in Amazon warehouses in Deltona, Florida; Waukegan, Illinois; and New Windsor, New York, to be “at high risk for lower back injuries and other musculoskeletal disorders related to the high frequency with which workers are required to lift packages and other items; the heavy weight of the items; awkward postures, such as twisting, bending and long reaches while lifting; and long hours required to complete assigned tasks.” “Each of these inspections found work processes that were designed for speed but not safety, and they resulted in serious worker injuries,” said Assistant Secretary for Occupational Safety and Health Doug Parker, in a statement.In our most recent internal survey—conducted randomly and anonymously—nearly 9 out of 10 of our colleagues say they feel safe at work and that their managers are doing all they can to ensure they’re safe.” It is true that the Jarrow Insights survey was not random—it was distributed via online ads targeted at people who identified themselves as working for Amazon on social media or who were geographically located within Amazon facilities (accounting for 75% of responses), as well as via outreach to worker organizations (7.6%), according to a Jarrow Insights spokesperson (the rest came from employees sharing the survey with colleagues).However, as the spokesperson for Jarrow Insights tells TIME, the group intentionally built a larger-than-statistically-necessary sample size to mitigate any potential problems due to the targeting approach of the survey design.In addition, the spokesperson says, they’re not claiming that the results represent all of Amazon workers, but rather just the respondents of the survey who identified themselves as Amazon workers.“The majority of workers surveyed expressed their belief that Amazon’s monitoring of their work performance is excessive and opaque, that its expectations are unrealistic, and that striving to meet these unrealistic expectations has negative effects on their physical health and, even more acutely, their mental health.” Read More: Amazon’s Dangerous Ambition to Dominate Healthcare It is not the first assessment to find Amazon’s workplace safety lacking."
