Among the possible consequences of occupational accidents, it is emphasized that although the physical damage are more easily perceived, psychiatric symptoms and disorders have been increasingly observed. In this context, Post-Traumatic Stress Disorder (PTSD) is one of the most common, causing injuries to workers and having great impact on their quality of life. The aim of this paper was to present a theoretical review of PTSD resulting from occupational accidents as well as review the psychological, socioeconomic and legal consequences triggered by the disorder. From the review of the literature presented, it is evident the impact of PTSD for the individual's life, with significant losses in their relationships and in the workplace. Finally, the discussion about PTSD in the work environment raises for consideration about prevention, assessment, treatment and compensation.
