Since 1910, the Teamsters logo has consisted of two horses’ heads, representing the complimentary forces of strength that are inherent in the Teamsters organization. A well-known emblem, most people recognize it but are unsure of the story behind it. The horses’ names are Thunder and Lightning, Thunder is male, Lightning female. Together, they symbolically represent the pillars of the Teamsters organization: quality and power, dignity and justice, strength and morality. The Teamsters are built on pillars that allow us to ensure that our Members’ needs are taken care of, that workers have access to their rights, and that our organization has the staying power to persist through the years.
