This is what bonded labor looks like in Pakistan. The practice, in which employers give high-interest loans to workers, whose entire families must then labor in an effort to pay off ever-mounting debt, is illegal, having been banned in 1992. It is also pervasive. The use of bonded child labor is punishable by a $900 fine and five years in prison.
