童工是全球重要问题之一。每年的6月12日为世界无童工日。各界人士开展主题活动，提高童工对儿童、家庭以及社会危害意识。通过无童工日，宣扬儿童人权保障。在联合国千年发展目标中，为解决童工问题设定了诸多目标。到2015年之前，完成对儿童的小学教育目标，从而促进儿童教育平等。为实现这一目标，政府必须采取措施减少贫困，增加成人就业率。童工现象原因有二。

There are over 250 million children worldwide who work in some kind of labour. Eighty percent of these, around 200 million, work in dangerous and hazardous conditions. A senior UNICEF spokesperson on child protection said: “Child labour is a widespread phenomenon all over the world. When that work stands between a child and his or her chances for education, or affects his or her health, then we consider this a violation of the rights of children.” There are many terrible forms of child labour. These include working in dangerous mines deep below the ground and being a slave in the sex industry. Many children are sold by their parents to raise money. Many more are beaten and abused by cruel employers, or sold by child traffickers.

全球有2.5亿童工。约2亿（80%）儿童的工作条件极其危险。“儿童基金会”儿童保护高官表示：“童工是全球性问题。童工阻碍了儿童受教育，儿童健康随即受到影响，那么我们认为这侵犯了儿童权力。”许多工作形式及其糟糕。包括井下开矿以及刑奴。许多儿童被父母贱卖挣钱。许多儿童遭受雇主毒打虐待，或被人贩售卖。
