In 1901, workers in Pennsylvania's silk mills went on strike. Many of them were young women demanding to be paid adult wages. The 1900 census had revealed that one sixth of American children under the age of sixteen were employed. John Mitchell, the president of the UMWA, brought Mother Jones to north-east Pennsylvania in the months of February and September to encourage unity among striking workers. To do so, she encouraged the wives of the workers to organize into a group that would wield brooms, beat on tin pans, and shout "join the union!" She felt that wives had an important role to play as the nurturers and motivators of the striking men, but not as fellow workers. She claimed that the young girls working in the mills were being robbed and demoralized. The rich were denying these children the right to go to school in order to be able to pay for their own children's college tuitions.
