The conference represents workers in all craft and skill areas in the printing and publishing industry. Every day, GCC members help print, produce and design numerous publications, including the New York Times, Chicago Sun-Times, San Francisco Chronicle, Elle and Cosmopolitan magazines, Harper Collins and Penguin books, brochures for Chevrolet and catalogs for L.L. Bean.

Members work in desktop publishing and electronic color prepress. They operate web and sheetfed, offset, letterpress, rotogravure, silkscreen and other specialty presses. They handle binding, finishing and shipping of finished products. They produce inks, paper and packaging materials made of paper, plastic, cardboard and metal. Graphic Communications Conference members are also journalists, graphic artists, typesetters, sales people and support staff. GCC members have received wide recognition for their high levels of skill and productivity in their workplaces.

The merger between the two powerful unions enables the now-stronger Teamsters Union to represent even more workers in printing and related industries. For example, the GCC and the Teamsters Newspaper Division represent different but complimentary types of hardworking employees at many major newspapers, such as the Cleveland Plain Dealer, Boston Globe, Boston Herald, Columbus Dispatch and the Star-Ledger in New Jersey.
