The purpose of this article is to theoretically reflect on how globalization has influenced the rupture in labor relations and the weakening of union organizations. In order to do this the following aspects were developed: flexibility in labor relations, the effects of capital and labor, the future of labor and the weakening of labor unions. The analysis of these aspects is based on a theoretical review that allows for the construction of a position as to the labor flexibilization correspond to world market criteria, affecting the fundamental rights of the labor force, promoting the individualization of labor relations, a de-regulated laborer, without a union, and without a collective contract among other benefits. The conclusion is that flexibility originates a rupture in labor relations, and results in a precarious labor situation and the exclusion of a labor market. On the other hand, the concept of the role of labor unions is devaluated, and the interests of capital are increased, debilitating labor autonomy and its role within the globalization process.
