Solution:Robert F. Hoxie has presented a sociopsychological approach to trade unionism in his book Trade Unionism in the United States (1920). According to him, trade unions grew out of the 'social psychological' environment of the workers.
He has said that 'workers who are similarly situated economically and socially, closely associated and not too divergent in temperament and training, will tend to develop a common interpretation of the social situation and a common solution of the problem of living.
This may come about gradually and spontaneously, or it may be apparently sudden outcome of some crisis in the lives of the men concerned. Hoxie has adopted a pluralistic approach to trade unionism.
According to him, trade unionism is the outcome of a group psychology that emerges out of social and environmental conditions and the temperamental characteristics of the members. Hoxie has classified trade unions on the basis of the functions perfonned by them. According to him, there are four types of trade unionism:
(i) business unionism.
(ii) friendly or uplift unionism.
(iii) revolutionary unionism and
(iv) predatory unionism. His followers added a fifth, dependent unionism, to the list-dependent unionism.
(i) Business Unionism: They are also known as Bread and Butter unions. These unions are trade conscious rather than class conscious. They accept the existing economic system and aim at bringing about improvement in the wages and working conditions of their membérs. Collective bargaining is the usual method of achieving their goal.
(ii) Friendly or Uplift Unionism: Such unions are idealistic in nature and elevate the moral, social and intellectual life of the workers. To achieve their aim these unions advocate use of political methods such as setting of cooperative enterprises, profit sharing and mutual insurance.
(iii) Revolutionary Unionism: Such unions are extremely radical both from a view point and in action. They are distinctly class conscious rather than trade consciousness. They aim at replacing the capitalistic system by socialistic system. They believe in political action or direct action in the form of strikes, boycotts, sabotage and violence.
(iv) Predatory Unionism: Unions of these types does not subscribe to any ideology. Such unions are characterized by their ruthless pursuit of immediate ends. They use collective bargaining, secret bribery and violence to settle their dispute. Gangsters dominate it.
(v) Dependent Unionism: Such types of unions are dependent on the support of workers or other labour groups. This type of unions appears in two forms - Company Union and Label Union. The former depend entirely on employer whereas the second type depends upon the label imprinted on the products made by the union members.
