Summary of key results: Five categories of informal learning were identified: interpersonal relationships; work practices; sharing knowledge; unsystematic training and autonomous. Informal learning depends on: 1. interpersonal relationships, 2. plan for work practices, 3. sharing the knowledge, and 4. autodidactism. Some factors were considered facilitators and/or inhibitors and favorable and/or unfavorable to informal learning. Key considerations/conclusion: The professionals describe informal learning as something difficult to prove and that the same thing happens through practice and the exercise of their skills. For future research, it was suggested the following: 1. analyze the influence of environment variables when employing the use of informal strategies of learning; 2. relate the learning of TIC professionals to the initiatives of knowledge management in the Organization; and 3. observe the role of leadership in the process of informal learning among professionals.version) • http://dx.doi.org/10.1590/1678-69712017/administracao.v18n1p66-95.
