Crosswaith maintained a long association with union head A. Philip Randolph, serving with him as officers of the Negro Labor Committee in the 1930s and 1940s.
[citation needed] In the early 1930s Crosswaith worked as an organizer for the International Ladies Garment Workers Union, which became one of the major supporters of the Negro Labor Committee.
He accused Kemp of undermining the interests of black workers by signing agreements with employers that offered them labor at wages below union rates.
[citation needed] Crosswaith also worked with A. Philip Randolph during World War II in organizing the March on Washington Movement, which was called off when President Franklin D. Roosevelt agreed to sign Executive Order 8802, which prohibited racial discrimination in defense industries.
