Children at Work Throughout History [PDF ebook] 

You may think you have it tough and work really hard, but not compared with children who had to work for a living in the past and even today. Although child labour laws are now in affect in many countries, in some places children still toil long hours in horrible conditions for little pay. Some are not even allowed to attend school. Children at Work Throughout History examines how labour laws have changed over the years in many countries but shows there is still work to be done to protect children and their rights worldwide.
