The industrial, work, and organizational (IWO) psychology domain might corroborate on new insights developed within the fundamental personality area, but also, vice versa, the personality field should also build upon applied research on individual differences. It is our conviction that these two fields developed too independently in the past. A selective number of issues and themes that cross the personality-IWO bridge are discussed that can be addressed in future research or implemented in professional practice, including processes explaining trait-performance relationships, trait assessment in the workplace, variable versus person centred approaches towards personality description, personality of teams and groups, and finally maladaptive personality functioning.
