In 1994 negotiations took place between the IBFO and the large Service Employees International Union (SEIU) which resulted a close affiliation with the boiler operators henceforth known as the National Conference of Firemen and Oilers (NCFO).On December 18, 1898, five delegates to the 18th Annual Convention of the American Federation of Labor (AF of L) got together to discuss issues of common concern to boiler operations workers.During the early years of the electrical generation industry, which were marked by relatively small and isolated individual generating plants, the Brotherhood of Stationary Firemen and its sibling rival, the International Union of Steam and Operating Engineers (IUSOE), played a relatively large part — comparable in jurisdictional status to the International Brotherhood of Electrical Workers (IBEW).[3] Over time this position of importance was largely lost, however, in part due to expanding use of hydroelectric plants as well as growth in size and jurisdictional authority of the IBEW — which by the end of the 1920s had become one of the four strongest unions affiliated with the AF of L.[3] The Brotherhood of Stationary Firemen and Oilers was swept by controversy in 1924 by allegations that its national Vice President and editor of its monthly magazine, Robert William Beattie, had for 12 years worked as a spy on behalf of a private detective agency.[1] On November 20, 1994, a special convention was convened in Washington, DC between delegates of the IBFO and those of the large-and-growing Service Employees International Union (SEIU).
