Research indicates that the well‐being and productivity of over 100 million people in the global workforce may be compromised by posttraumatic stress (PTS). Given that work‐related experiences are often the source of the trauma that leads to PTS, and that PTS due to any cause can interfere with employees’ job performance, organizations would do well to consider the antecedents and consequences of PTS. This review of research—primarily within fields adjacent to business—on the types, antecedents, consequences, and organizational implications of PTS is presented to advance inquiry within the field of business. The definition of PTS requires attention to the new classification of complex posttraumatic stress disorder that can result from threats that are not life‐threatening such as bullying and sexual harassment. PTS antecedents include organizational and extraorganizational traumas, and risk and resilience factors. Absenteeism, impaired cognitive functioning, strained relationships, and growth are among the consequences of PTS. Organizations can assist through disaster planning, empathetic leaders, mental health literacy initiatives, and employee assistance programs. Many research questions arise that, when answered, will allow organizations to better understand how they can improve employee productivity and well‐being by attending to PTS.
