Child labor started in the late 1700 and early 1800. People with to many children they would send them off to a farm, a tavern, or even mill houses. In the farm they would have to do farm work for so long and then they would be payed $0.50 per week. In the tavern you would work in till they were done with there jobs and at the end of the week they would payed $0.50. In the mills you got payed $2.00 each week. Mill working got you good money but it was hard to see and breath because of all the lint and dust in the air. It was very hot in the mill house. The coal miners would get $1 to $3 each week. It was very dangerous in the coal mines because they could fall and kill the children and if they lit a candle the fumes in the the hole cave or cavern would explode. They will be very badly hurt or die.
There are lots of different types of child labor like working in the mills, miners, factory workers, seafood workers, working in a field or farm, salesmen, shoe shining, lumber worker, and more. They would not get payed much and all the money would usually go to the parents. The parents would do this so they did not have to work. The children could often be hurt in any of the job that they had. They could get there hand stuck in the machine in the mill and it would sever there hand. They could die by being crushed by the cave.
