The images on IBEW T-shirts represent individual local union chapters of the International Brotherhood of Electrical Workers. IBEW represents employees in the fields of utilities, construction, telecommunications, broadcasting, manufacturing, railroads and government.
The IBEW logo consists of a human hand holding electrical currents in the center of a dual circular patch. The outer circle generally specifies the individual union chapter of the IBEW, and the inner circle states "The International Brotherhood of Electrical Workers." The International Brotherhood of Electrical Workers represents members in both the United States and Canada, and is one of the largest unions in the American Federation of Labor-Congress of Industrial Organizations, also known as the AFL-CIO.
