It is an advisory assembly composed of "social partners", namely: employers (employers' organisations), employees (trade unions) and representatives of various other interests. Its seat, which it shares with the Committee of the Regions, is the Jacques Delors building on Belliardstraat / Rue Belliard 99 in Brussels. Once known by the acronym "EcoSoc", the body is now referred to as the "EESC", to avoid confusions with the United Nations ECOSOC.
