On the basis of the results presented on the research project entitled "Changes of the world of work on the communication companies", this article discusses characteristics of the values and choices inherent to the work activity of professionals of communication. The first part discusses the centrality of the work and of the communication on the contemporaneous society. Here the theoretical reference is the concept of human activity of work, from which an approximation between the ontology of the social being of Marx and the ergological approach is established. On the second part of the article we discuss the contradictions, evinced by the research project, that are present on the professional practice of the communication in relation to the right to information. The research project presents the analysis of data obtained by means of interviews with professionals of communication, employees of two different communication companies. The discussion allows us to evince the professional values and the injunctions of the system of production on the selfdebates and selfconflicts that the workers faces when making their professional choices, in the context of the system of the big conglomerates of communication and media fusion companies. As a conclusion a balance of the indicators resulted from the research is presented.
