"Former Amazon Employees Helped Make a Hotline to Report Unsafe Working Conditions", 3 September 2019

...the Free and Fair Markets Initiative...has teamed up with former Amazon workers to create a hotline for reporting unsafe working conditions...

 ...the group has been focused on "scrutinizing Amazon's harmful practices," especially as the company plans new expansions without adequately addressing its workplace conditions...

...The hotline not only allows a worker to work around a fear of retribution or inadequate care, but also gives instructions and resources for taking their complaint even further by filing with OSHA either online, physically, or over the phone.

“We work hard to provide a safe, quality work environment for our associates, who are encouraged to provide feedback through public and private channels and are always welcome to talk to leaders at their site — 24 hours a day, 7 days a week,” Amazon said in a statement. “All of this is on top of our industry-leading $15 minimum wage and comprehensive benefits starting on day one—we encourage anyone to compare our safety record, employer practices, and work conditions with any major employer or retailer.”
