The growing technological innovation that has taken place in recent years has demanded training geared to the new reality. Education often ends up bearing the brunt of the shortfall in training workers with knowledge and skills suited to the market. Faced with this shortage, companies have sought to produce their own means of training aimed at satisfying their immediate interests, which has come to be characterised as in-company training. The main objective of this study was to analyse the multiple aspects of the teaching/learning process in these non-formal spaces, both from the point of view of the teachers and the students/workers. The research was quantitative and qualitative and the data was collected through semi-structured interviews and questionnaires. It was carried out in two companies in the southern region of Santa Catarina and involved (15) workers and (10) teachers who work directly in these spaces.
