It is difficult to obtain reliable estimates concerning the number of children trafficked each year, primarily due to the covert and criminal nature of the practice. The International Labour Organization estimates that 1.2 million children are trafficked each year.Child labor refers to the employment of children in any work that deprives children of their childhood, interferes with their ability to attend regular school, or is mentally, physically, socially or morally dangerous and harmful. The International Labour Organization considers such labor to be a form of exploitation and abuse of children. Child labor refers to those occupations which infringe the development of children (due to the nature of the job or lack of appropriate regulation) and does not include age appropriate and properly supervised jobs in which minors may participate. According to ILO, globally, around 215 million children work, many full-time. Many of these children do not go to school, do not receive proper nutrition or care, and have little or no time to play. More than half of them are exposed to the worst forms of child labor, such as child prostitution, drug trafficking, armed conflicts and other hazardous environments. There exist several international instruments protecting children from child labor, including the Minimum Age Convention, 1973 and the Worst Forms of Child Labour Convention. More girls under 16 work as domestic workers than any other category of child labor, often sent to cities by parents living in rural poverty such as in restaveks in Haiti.
There is no mandatory reporting law, which would grant reporters of child abuse anonymity and immunity. United States
In the 1960s, mandatory reporting in the United States was introduced and had been adopted in some form by all 50 states by 1970.: 3 
In 1974, the Child Abuse Prevention and Treatment Act (CAPTA) was introduced and began an upswing in reported child sexual abuse cases which lasted until the 1990s. The Child Abuse Victims Rights Act of 1986 gave victims of child abuse the ability to file lawsuits against abuse perpetrators and their employers after the statue of limitations had expired. The Victims of Child Abuse Act of 1990 further gave victims of abuse capacity to press charges by permitting the court to assign lawyers to advise, act in the best interest of, and elevate the voices of child victims of abuse. The Adoption and Safe Families Act (1997) followed, shifting emphasis away from court-sanctioned reunification of families to giving parents or guardians time-bound opportunities for rehabilitation prior to making long term plans for children. Child Abuse Reform and Enforcement Act was enacted in 2000 to further reduce the incidence of child abuse and neglect. Shifting legislative focus more heavily towards sexual abuse and exploitation of children, Adam Walsh Child Protection and Safety Act was passed in 2006 to increase penalties and registration for child sexual abuse, exploitation, and transportation crimes.
