[2] In March 1912, Casey's efforts in Michigan were focused on the concerns of female workers at the Kalamazoo Corset Company including low wages, long hours in unsanitary conditions and sexual harassment from male foreman.

Organizers, including Pauline Newman and Gertrude Barnum,[3] and striking employees gained national attention for silent picketing and prayer meetings in response to a court order to stymie disorderly picket lines.

An agreement that fell short of significant wage gains, but marked progress for female workers' rights, was reached on June 12.

In 1931 the National Woman's Party (NWP) contacted her and sent her to Atlanta to oppose the efforts by the Southern Council and the Cotton Textile Institute to establish sex-based legislation.

Her reports were made into a regular column featured in the NWP's weekly bulletin Equal Rights.
