The object of this degree work was focused on how informal communications influence the formal logic of a Colombian mining organization and the logics of the actors involved in it. To do this, the qualitative methodology was an essential input along with the approaches of the recursive problematization and the look of social constructionism. Additionally, the data collection was done by conducting twenty field diaries, six semi-structured interviews and the analysis of formal documents of the mentioned organization. Moreover, the results were obtained by performing matrices of meaning, that led to twelve recurrences in which was hegemonic the hollowing of meaning of the formal communication that comes from the essence of the mining activity: which is the hollowing action for financial gain, and the caste hierarchy of each one of its areas. This has an impact on the organizational culture of the company, because it prints on it a stamp of fragmentation among its areas, leading to the exclusion of the concept of worker and their own wellbeing. Therefore, the formality of this company lacks of unity and the idea of a worker, by which it finds itself in a process of self-destruction reflected in vacuum, and the creation of an informal and underground world that resists against such destruction by a communicative exercise that provides meaning and direction.
