This doesn't surprise me because there are multiple reports scattered across the internet, about Walmart treating employees badly. Walmart does whatever is in Walmart's best interest, and I no longer shop there if I can absolutely help it.
For that matter, I'd love nothing better than to see Walmart close it's doors and fade into history forever, because they single-handedly killed off Main Street America, and I despise them for it.
Just say no to ChinaMart (AKA: Walmart).
Not an expression of an opinion, just an observation. Walmart has had an even bigger impact on middlemen and wholesale warehouses. Walmart negotiates their own deal with the suppliers. The story of Vlassic Pickles is interesting.
