Alienation in general is a state in which human life is dominated by the forces of human invention that give us control over nature. The particular alienation that Marx described is the loss of control people feel in the workplace as a result of the separation of workers from the products of their labor. The four levels of alienation are alienation from (1) the process of production, (2) the product, (3) the family and the community of fellow workers, and (4) the self. Workers are alienated from the process of production because they do not produce products for themselves or known consumers but for an abstract, impersonal market. They are alienated from the product because their roles are rote and limited. Workers are alienated from the family and fellow workers because work and family environment are separate from one another. Workers are alienated from themselves because their skills are used at the convenience of management in the quest for private profit.
