Children were very profitable assets since their pay was very low, were less likely to strike, and were easy to be manipulated. Socioeconomic disparities and lack of access to education are among others contributing to the child labor. Religious and cultural beliefs can be misguiding and concealing in delineating the limits of child labor. Child labor prevents physical, intellectual, and emotional development of children. To date, there is no international agreement to fully enforced child labor. This public health issue demands a multidisciplinary approach from the education of children and their families to development of comprehensive child labor laws and regulations.
Child labor is an old problem well rooted in human history. Children were exploited to various extents during different periods of time. The problem was common in poor and developing countries. In the 1800's, child labor was part of economic life and industrial growth. Children less than 14 years old worked in agriculture, factories, mining, and as street vendors. Children from poor families were expected to participate to the family income, and sometimes they worked in dangerous conditions in 12-hour shifts.
In the 1900's, in England, more than a quarter of poor families lost their children to diseases and death, endangering their extra financial support. Boys worked in glass factories in high heat in three shifts because the furnaces were kept fired all the time to increase productivity, while girls were forced into prostitution. In 1910, it was estimated that more than two million children in the United States were working.
With the increase of education, economy, and the emergence of labor laws, child labor decreased. However, child labor is still a widespread problem in many parts of the world in developed and developing countries. With the development of agriculture, children were again forced to be employed mostly by the families rather than factories. The main cause of child labor is the lack of schools and poverty.
Per International Labor Organization (ILO, 2002), in the world, there are 211 million children laborers, 73 million under 10 years of age, 126 million children work in the worst forms of child labor, and more than 8 million are kept as slaves for domestic work, in trafficking, armed conflict, prostitution, and pornography. More than 20,000 children die yearly due to work-related accidents. Nearly, one-third of the world's children work in Africa. Countries such as India have made efforts to tackle the worst forms of child labor. Despite this, 56.4% of children aged 5–14 work in agriculture and 33.1% work in industry. Indian children are forced into labor to pay family debt. They work sometimes in hazardous environments, being forced into commercial sexual exploitation, human trafficking, or forcibly recruited or kidnapped to be part of terrorist groups.
Child labor is morally and ethically unacceptable. United Nations Children's Fund (UNICEF) was the first international body that signed in 1989 the Convention on the Rights of the Children. It is for the first time in history when children are seen as humans with rights rather than economic assets of their parents. Child labor was defined as labor that harms the health of the children and deprives them of education rights. This law does not exclude children that work for their families.
