The purpose of this article is to put forward a discussion on the evolution and structure of the roles played by the personnel and human resources department in the Beta Enterprise, identifying the reality, indexers and results for that company. The study articulates inter-linked elements for the evaluation of the evolution: the environment and its changes; the organization through updated human resources politicies. After identifying these events for the past 10 years a decriptive/qualitative survey was developed, through the statements by the representatives of the human resources area in the company ( BETA Enterprise ) whose headquarters are in Belo Horizonte, featuring an industrial plant in Vale do Aço, Minas Gerais, for the collection of data on its policies and practices in human resources. A book research on the theme as well as documental research were also carried out. Results point at some convergence with traditional, modern and contemporary theories on human resources.
