The term UNION FOE is composed of three words: SCAB (4 letters), REB (3 letters), and SOUTH (5 letters). SCAB is a derogatory term for a worker who takes the place of a striking worker, while REB is an abbreviation for a Confederate soldier during the American Civil War. SOUTH is a geographical direction. Together, these three words can be interpreted as a reference to the conflict between labor unions and employers in the southern United States during the 19th century.
