The role of Trade Unions in business concerns are as follows :
(i) Intra-mural activities : The intramural activities refer to those efforts of trade unions which are mainly performed for the betterment of workers in relation to their employment. Through these activities trade unions ensure adequate wages, better working conditions, better treatment and a reasonable share and control in the management and profit of industry.
(ii) Extra mural activities : These activities refer to those activities of the trade union, which are performed, for providing help to workers in time of need. Thus, trade unions help the workers in case of sickness and accident and give them financial support during the period of unemployment, strikes and lockout. They also foster a spirit of co-operation and diffuse education among labourers.
(iii) Political activities : Trade unions also contest elections and try to send their representatives in Parliament and State Legislatures. In India, such development is not yet significant and trade unions are politically unorganized.
