Would it then be reasonable to fabricate injuries in order to game performance assessments?

I actually work inside one of Amazon's FCs on the West Coast. The managers in my department, actually encourage us to notify them if anything starts to feel out of the ordinary, in an effort to keep a little thing (overreaching instead of using the ladder, can cause shoulder strain, not bending at the knees can cause back strain, knee strain, not grasping product correctly can cause finger/wrist strain, even any of the physical effects of not staying hydrated while working) from turning into a big thing.
