Child labour.

Child labour refers to the exploitation of children through any form of work that deprives children of their childhood, interferes with their ability to attend regular school, and is mentally, physically, socially or morally harmful. Such exploitation is prohibited by legislation worldwide, although these laws do not consider all work by children as child labour; exceptions include work by child artists, family duties, supervised training, and some forms of child work practiced by Amish children, as well as by indigenous children in the Americas.

Child labour has existed to varying extents throughout history. During the 19th and early 20th centuries, many children aged 5–14 from poorer families worked in Western nations and their colonies alike. These children mainly worked in agriculture, home-based assembly operations, factories, mining, and services such as news boys—some worked night shifts lasting 12 hours. With the rise of household income, availability of schools and passage of child labour laws, the incidence rates of child labour fell.

In the world's poorest countries, around one in four children are engaged in child labour, the highest number of whom (29 percent) live in sub-saharan Africa.[12] In 2017, four African nations (Mali, Benin, Chad and Guinea-Bissau) witnessed over 50 percent of children aged 5–14 working.Worldwide agriculture is the largest employer of child labour.The vast majority of child labour is found in rural settings and informal urban economies; children are predominantly employed by their parents, rather than factories.Poverty and lack of schools are considered the primary cause of child labour.

Globally the incidence of child labour decreased from 25% to 10% between 1960 and 2003, according to the World Bank. Nevertheless, the total number of child labourers remains high, with UNICEF and ILO acknowledging an estimated 168 million children aged 5–17 worldwide were involved in child labour in 2013.

Early 20th century.

In the early 20th century, thousands of boys were employed in glass making industries. Glass making was a dangerous and tough job especially without the current technologies. The process of making glass includes intense heat to melt glass (3133 °F). When the boys are at work, they are exposed to this heat. This could cause eye trouble, lung ailments, heat exhaustion, cuts, and burns. Since workers were paid by the piece, they had to work productively for hours without a break. Since furnaces had to be constantly burning, there were night shifts from 5:00 pm to 3:00 am. Many factory owners preferred boys under 16 years of age.

An estimated 1.7 million children under the age of fifteen were employed in American industry by 1900.

In 1910, over 2 million children in the same age group were employed in the United States.This included children who rolled cigarettes, engaged in factory work, worked as bobbin doffers in textile mills, worked in coal mines and were employed in canneries. Lewis Hine's photographs of child labourers in the 1910s powerfully evoked the plight of working children in the American south. Hine took these photographs between 1908 and 1917 as the staff photographer for the National Child Labor Committee.

Cultural

In European history when child labour was common, as well as in contemporary child labour of modern world, certain cultural beliefs have rationalised child labour and thereby encouraged it. Some view that work is good for the character-building and skill development of children. In many cultures, particular where the informal economy and small household businesses thrive, the cultural tradition is that children follow in their parents' footsteps; child labour then is a means to learn and practice that trade from a very early age. Similarly, in many cultures the education of girls is less valued or girls are simply not expected to need formal schooling, and these girls pushed into child labour such as providing domestic services
