The democratic upheaval in politics exemplified by Jackson's election was merely one phase of the long American quest for greater rights and opportunities for all citizens. Another was the beginning of labor organization, primarily among skilled and semiskilled workers. In 1835 labor forces in Philadelphia, Pennsylvania, succeeded in reducing the old "dark-to-dark" workday to a 10-hour day. By 1860, the new work day had become law in several of the states and was a generally accepted standard.
