In 1921, Tobin helped defeat an amendment offered by African American union members which would have forced all members of the AFL to remove the word "white" from their constitutions and to admit all workers regardless of race, creed or nationality. Although three resolutions were offered, only one made it to the convention floor. When black delegates attempted to bypass the Committee on Organization (which had jurisdiction over the resolutions) and introduce the amendments on the floor of the 1921 AFL convention, Tobin supported Gompers in declaring the amendment out of order because it violated the AFL's explicit policy of noninterference in its members' affairs.
