The objective of this article is to present the actual state of building knowledge about work's happiness and its significance, as well as the field of knowledge of positive psychology in business organizations and workplace.For that, an integrative review was carried out, through 24 articles indexed in the databases Pepsic, Lilacs and Scielo.It was observed that well-being, especially the subjective, is used as a synonym for happiness.Although related, the concepts of well-being and happiness, present distinctions, due to their specificities.In only two articles, they used happiness as a phenomenon without associating with another construct, one being published by Barros, Martín and Pinto (2010) and the other by Silva and Tolfo (2012).Through the studies carried out here, it was possible to discover that the interest in the subject, although it is intensifying, is recent in the academy and such scarcity represents an opportunity for the development of new studies.The construction of Happiness at Work represents a challenge for psychologists interested in understanding about the subject.Such scarcity represents an opportunity for the development of new studies, with the intention of discovering, new and positive perspectives of life, for all those interested in the organizational life.
