"One of the major aims set for the International Labour Organization (ILO) at its foundation in 1919 was the abolition of child labour. Historically, the ILO’s principal tool in pursuing this goal has been the adoption and supervision of labour standards that embody a minimum age for admission to employment or work. Furthermore, from 1919 onwards the principle that minimum age standards should be linked to schooling has been part of the ILO’s tradition in standard setting in this area." (Quoted from article)
