The concepts of child labor and child education both are inversely linked with each other in terms of execution. Child labor does not allow child education and vice versa. Between the two types of economic ideologies normative approach promote child education but other ideology i.e. positive approach have preferred child labor. It is factual that, child labor, however, become a burden for every economy. It is a serious problem in any nation. Economy never accepts child labor and the high volume of child labor creates liability on economy. Any job of children always treated as the problem of underemployment through the labor market framework and all child work are strongly prohibited by ILO. The main aims of this paper find out the basic causes of children are recognized as child labor and try to know the causes behind existence a negative relationship between child education and child labor. In Bangladesh, the volume of child labor is so high, near about 4.7 million children, age limit of 5-14 years of age were economically active and percentage of labor force participation rate was 13.4 in the year 2002-03 [National Child Labor Survey (NCLS)]. On the other hand, the figure of informal activities of children is higher than above figure. If we compare with South-Asia, our labor force participation rate is higher than rest of the nations. So policy maker should concentrate to ameliorate education of children and reduce child participation (reduce in number) in economic activity as well as unpaid work.
