Ms. [Santa] Castillo had long dreamed of a bigger, sturdier house... [T]hree months ago something happened that finally made it possible: she landed a job at one of the world’s most unusual garment factories. Industry experts say it is a pioneer in the developing world because it pays a “living wage”... and allows workers to join a union without a fight...The factory is a high-minded experiment...It has 120 employees and is owned by Knights Apparel, a privately held company based in Spartanburg, S.C., that is the leading supplier of college-logo apparel to American universities...Joseph Bozich, the C.E.O. of Knights, is optimistic. “We’re hoping to prove that doing good can be good business, that they’re not mutually exclusive,” he says. Not everyone is so confident...Andrew Jassin, an industry consultant...says “fair labor” garments face a limited market...[T]his new, unknown brand could face problems being sold alongside Nike and Adidas gear...Nike and Adidas officials said their companies have sought to improve workers’ welfare through increased wages...A Nike spokesman said his company would “watch with interest” the Knights initiative.
