Historical background of trade union:-
Union oriented, mainly in Great Britain the U.S.A in the late 18th and early 19th centuries, as, associations of workers using the same skill. There is no connection between trade unions and medieval craft guilds, for the latter were composed of master craftsmen who owned capital and often employer several workers. The early unions were formed a partly as social clubs but soon became increasingly concerned with improving wages and working conditions, primarily by the device of collective bargaining. Progressing from trade to trade within the same city or area, the clubs formed local associations which, because they carried on their main activities on a purely local level, were almost self-sufficient. With industrial development, however, local associations sooner or later followed the expansion of production beyond the local market and developed into national unions of the same trade. These in turn formed national union federations.

Labor group tried hard and soul for establishing their rights. As a result, law was passed in many countries in favor of trade union. In 1836 the trade union commotion was found in Brussels, which is treated as INTERNATIONAL MOVEMENT OF TRADE UNION.
