Stacy Fahrenthold’s paper examines the labor politics of Syrian garment workers in New York City, women who stitched kimonos in factories operated by Syrian American merchant-manufacturers. Previously deemed “unorganizable” by unions on account of the Syrian community’s strong diasporic ties, Syrian workers struck with the ILGWU between 1916 and 1934, organizing their ethnic networks to support work stoppages. Aimee Loiselle’s paper focuses on Puerto Rican needleworkers on the main island and in the northeast who joined the ILGWU between 1930 and 1990. These women not only fought for better working conditions but also challenged colonial and international trade policies, attempting to set the terms of both labor activism and globalization. Devin Naar’s paper examines the involvement of Ladino-speaking Sephardic Jewish women workers in New York City. He highlights the challenges and opportunities that Sephardi women workers from the Ottoman Empire negotiated in their interactions with activists from Yiddish-speaking, Syrian, and Puerto Rican communities. All three papers rely on the blended methodologies of migration/diaspora studies and labor history, and on the use of oral histories, ethnic society records, private papers, and personal correspondence in addition to formal ILGWU archival collections.
