There are three main approaches to industrial relations: unitary, pluralist, and Marxist. The unitary approach believes conflicts are temporary issues that can be resolved through improved management and teamwork. The pluralist approach sees conflicts as inevitable due to different groups within an organization having different aims and objectives. It advocates for collective bargaining between management and recognized trade unions. The Marxist approach views conflicts as a product of the capitalist system and sees trade unions as a means for workers to react against exploitation by management and create social change.
