Where was this? Because that's not true in the US, land of the personal injury attorney. My brother used to be a machine salesperson. He got a call from a law firm couple years after his company sold a machine asking about a particular one that was sold (not even by him) because their client lost a body part. Those payouts often end up in the millions.
It looks like a company was using uninformed and "scared" employee population to commit labor violations. Also using the same tactic that I alluded to in one of my other comments: Production workers are hired from a staffing agency and dispatched to the job site, that way the company HR doesn't know(and can't legally ask about work eligibility).
It looks like that plant in particular has serious issues. Someone else died after the 16 year old, bringing the number of deaths in recent years to 3.
This one in particular seems to know what it is doing: Googling "Mar-Jac Poultry" does not bring up any of the issues, nor are they listed in the Wiki page.
