The author presents certain aspects of terminological work in a corporate environment from the point of view of a technician. In Brazil, there is a dichotomy between the terminological work as conducted by professional linguists and by the technicians which create and make use of terminology in the several fields of (industrial, commercial, etc.) activities. It is therefore generally accepted that the several actions conducted in these fields should be integrated through a single Terminology Commission, with structure and objects similar to the TC 37 of the International Organization for Standardization (ISO).
