Due to the global production system development, it have been generated a continuous process of elimination of jobs. Prosperity zones of economic cycles have become more and more insufficient, in order to recover lost jobs during the lasts recessions. The nature (characteristics) of the technological park, (media) in capital and knowledge, is the main reason why the investments, that generate not too much knowledge or jobs, are even bigger each time. Due to this situation, have been accumulated in many places, an space of hard cessation and other wider of precarious jobs. Jobs outside of the limits of labor legislation, with a poor remuneration, for short periods of time, informal. This situation affects all professions, occupations and arts, although in a different way. The phenomenon of work erosion is too much known in Latin America. The "surprise" is that this phenomenon is becoming to be naked, discovered in the very same territories that are the home of the architects of the global system for the production, consumption and distribution. Therefore, nowadays it is used the term a "thirdworlded" planet. This paper pretends to demonstrate the phenomenon of the precarious job, in general, and how the information workers, that form part of that fragile environment, or that unemployed, or looking for job for their first time, could implement strategies, in order to have a non-precarious job. Also alert those lucky persons, that have an stable job and a decent salary, about a possible deterioration of their labor status, and how they should prepare themselves in order to know about this threats before its appearance and the ways to face it.
