Florence kelley's solution to child labor:

Child labor is where children are made to work in factories and industries which are very harmful for their health and is illegal to make children work at small age. In the year 1894, Florence Kelley and Alt-geld tried to control child labor where they both tried to persuade the state legislature to pass a law where they could control and reduce child labor. They wanted to make a law where the working time of children is reduced to eight hours only in a day and working hours for women should also be limited.
