Child domestic work is a complex phenomenon that gives rise to conflicting perspectives as it mainly stems from the reality of children having to work due to household poverty. Against this background, it is at times regarded as beneficial as the employment provides the child with income, food and shelter. However, in opposition to this, there are conceptions of child domestic work as a form of modern form of slavery and holds it to be harmful for the concerned children. As its permissibility is contingent on its effects on the concerned children, which is hard to measure and thereby hard to get by, this thesis aims at investigating the implications of the child domestic workers' human development. This will be done by looking at the effects of the working conditions on the concerned children's wellbeing which will be analysed through the capability approach. The result shows that the practice of child domestic work impedes on the human development of the concerned children as it negatively affects their capability set through which the well-being of the concerned children is measured. It can thereby be stated that child domestic work is detrimental for the children's human development. With this, the current study provides insights on how to regulate child domestic work, as impermissible child labour and not as permissible child work.
