The focus of the 2016 World Day Against Child Labour is on child labour and supply chains. With 168 million children still in child labour, all supply chains, from agriculture to manufacturing, services to construction, run the risk that child labour may be present. Enterprises need to be vigilant to ensure that their supply chains are free from child labour or risk having their reputations ruined and their business seriously damaged. This ILO brochure details what businesses are doing to clean up their supply chains.
