That would make sense to me if this particular warehouse/region/whatever was characterized as having notably worse conditions than others. Reading about Amazon warehouses, it seems like a pretty universally bad working environment, regardless of which one.
My feelings are bit of a mix bag, some of the complaints I would agree, but some of them seem to be either employee or more likely media exaggeration.
I have no respect or trust of "main stream" media so the reporting on the issue has me questioning what the reality on the ground really is, and the reality from people experienced in working at other warehouses.
