The labor parties formed in Pennsylvania, New York, and Massachusetts in the 1820s advocated for an end to imprisonment for debt, which was a common practice at the time. They also called for other reforms, such as improved working conditions and higher wages for workers. However, they did not specifically advocate for a four-day work week, a pension plan guaranteed by employers, or free room and board for mill workers.
