*Not as many kids get hurt or killed in job related accident
*Kids can go to school and get an education
* They keep kids from being over worked
*You can't work in certain job types
*The company may have to alter the workplace to meet the requirements for a child to work there.
I think that only being able to work a certain number of hours in a week could be a positive and a negative. It could be a positive because it keeps children from being over worked. It could be a negative because if you really need money it prevents you from working over a certain number of hours to earn more money.
