Thomas Alfred Rickert (April 24, 1876 – July 28, 1941) was an American labor union leader.
Born in Chicago, Rickert studied business, but then became a garment cutter, and joined the United Garment Workers of America. In 1904, he was elected as president of the union. As leader of the union, he was regarded as a strong negotiator, and a close associate of Samuel Gompers. However, two-thirds of the union's membership split away to form the Amalgamated Clothing Workers of America, alienated by Rickert's conservative approach.[1][2]
