Well, how else do you think they make all those keys? They are stamped out by a large brass stamping and grooving machine, then hooked onto the assembly chain link by workers with small, nimble fingers and really good eyesight. Myopia, arthritis, itchy fingers, keypull tunnel syndrome, dizziness, and postal fever are common work-related injuries. The company, however, provides full medical care, including eyeglasses, talcum powder, recalled Vioxx, and orthopaedic and psychiatric visits. No weapons or ammunition are allowed on the factory floor or lunchroom.
