The International Labour Organization (ILO) defines child labor as work that "is mentally, physically, socially or morally dangerous and harmful to children; and interferes with their schooling by depriving them of the opportunity to attend school; by obliging them to leave school prematurely; or by requiring them to attempt to combine school attendance with excessively long and heavy work."[9] Not all work that children do is child labor. Work done that is not detrimental to children’s health, development or schooling is beneficial because it allows children to develop skills, gain experience and prepare them for future positions;[9] these are not considered child labor.[9]
