Had a friend that was a butcher at walmart back when there was talk of unionizing. It was a walmart in a small town and the moment even a rumor of unions started spreading, walmart was flying in corporate jets full of lawyers and psychologists and educators to make sure that no one unionized.

I guess they decided the risk was too great so they shut down their meat packing section in every store across America. I believe to this day, there are no butchers in walmarts. They bring in the meat pre-cut and pre-packed. Probably by a wholly owned subsidiary that they can easily shut down if things ever go sideways.
