This view of industrial relations is a by product of a theory of capitalist society and social change. Marxists argue that industrial relation is a relation of clashes of class interest between capital and labour. Employer (capital) tries to maximize profit by holding surplus value and underpaying workers remuneration. Workers clash for his share in the outcome of wealth because he is the human means of production, so the most important factor of production. Industrial relation is a continuous process of clash of interest between capitalist and labour. This clash will finish in the socialist society only, where capital is controlled by labour class. Marxist Perspective of Industrial Relation argue that:
This perspective focuses on the fundamental division of interest between capital and labor, and sees workplace relations against this background. It is concerned with the structure and nature of society and assumes that the conflict in employment relationship is reflective of the structure of the society. Conflict is therefore seen as inevitable and trade unions are a natural response of workers to their exploitation by capital.
