The author analyzes the consequences of globalization in the employment in Toluca’s metropolitan area, especially in the period from 1980 to 2000. There are evidences of a consolidation of work’s tercerization and precarization, with a typical feminization and adolescentization in a very vulnerable situation, and a segmentation of the tertiary employment, increasing unemployment and workers rotation. It is a significative change, characterized by the importance of informal employment and by labor conditions violating the workers’ rights and a lack of trade union organization.
