The document outlines three primary perspectives on employment relations: unitarist, pluralist, and marxist, each providing distinct insights into workplace dynamics. The marxist perspective emphasizes class conflict, exploitation, and the struggle for workers' rights within capitalist societies, advocating for collective action and a transformation of the system through a proletarian revolution. Criticisms of the marxist viewpoint include its oversimplification of employee relations and concerns about the practicality and efficiency of proposed socialist systems.
