Tyson Chicken.
This part is my theorizing: A bunch of workers were getting... uppity... about little things like child labor laws, blatant OSHA violations. Making a bit of noise.
They also happened to be mostly undocumented.
This part is fact:
ICE conducted coordinated raids on Tyson facilities and picked up ~900 undocumented workers.
Many of those workers supplied ICE and the media documentation from Tyson describing how to handle onboarding, I-9, IRS paperwork if they were undocumented - i.e. Tyson was actively aware, and actively assisting, in this.
For note: entering improperly or overstaying a visa is a crime - a misdemeanor. Aiding and assisting in this process is a felony (often because there's good financial gains to be made).
ICE held a triumphant press conference to herald this roundup.
Media question: "Does ICE have any plan to investigate Tyson, given the evidence that strongly suggests they were assisting these undocumented workers in staying under the radar?"
"That is not within the scope of our investigation here."
To absolutely no-one's surprise, this (and other similar situations like it) just ... don't get investigated.
My theory, again: Tyson was annoyed. Too much noise about OSHA and labor law violations. A little call to ICE, and a little backroom deal. "We'll give you the names of hundred of workers, you can make a big scene about that. And in exchange, you won't ask awkward questions about just how nearly 1,000 undocumented workers are at our facilities."
