Generally, Child Labour is a work for children that harms them or exploits them in some way. There is no generally accepted definition of "child Labour". Varying definitions of the term are used by international organizations, trade unions, non-governmental organizations, and other interest groups. Speakers and Writers don't always specify what definition they are using, and that often leads to confusion.
A child who delivers newspapers before school might really benefit from learning how to work, gaining responsibility, and earn a bit of money. If the child is not paid? Then he or she is being exploited. Children's work needs to be seen as happening along a continuum, with destructive or exploitative work at one end and beneficial work -enhancing or promoting children's development without interfering with their recreation, schooling and rest - at the other. And between these two poles are vast areas of work, which need not negatively affect a child's development." Other social scientists have vaguely different ways of drawing the line between unacceptable and acceptable work.
