Yes, they have. It doesn’t matter if an employee is twice as efficient if their injury rate is twice as high. If you are going to work and have twice the risk of injury, that’s a very bad thing. This is about injuries per employee, not injuries per item picked.

Theoretically, a system could be designed where all safety standards were ignored and productivity was n times more per employee, with lower injuries per item picked, but would result in astronomical injury rates. If you were an Amazon employee, would you want to go to work where there was a 1/10 chance per day you’d be injured? A 10x more efficient warehouse employee isn’t making 10x more money, so they are seeing increased risk for no personal gain.
