Somewhere I have similar pics that I took when I drove truck into and out of a DHL sorting facility. When you hire workers who do not care, and you push them to get things done quickly, and do not treat them like they will be back tomorrow, thats what you will get. After they got caught twice with illegal workers, they switched to American workers, and paid a decent wage. Last time I was there, it was like a entirely different place. Treat people like humans, And they will do better then if you treat them like slaves.
