When Brijesh Yadav borrowed US$300 from a contractor for his sister's wedding, it was the beginning of a long nightmare. To pay it back, he and his family travelled some 1,000 kilometres from the impoverished northern Indian state of Uttar Pradesh to work in a brick kiln in the wealthy western state of Gujarat. "They would beat me day and night," Brijesh says of the kiln's managers. "I have worked as a labourer [on farms] for many years but that was the first time I was beaten."
