Abstract
Although personality is typically conceptualised in industrial, organizational, and vocational psychology as enduring and stable, an increasing volume of research now shows that personality changes throughout the lifespan, with work being a potentially important influence of trait development. This paper reviews and integrates the emergent literature in this area, and in doing so proposes a new Demands-Affordances TrAnsactional (DATA) model of personality development at work, against which research is evaluated. This DATA model clarifies how personality-related behavior at work is called upon by work demands at four different levels (vocation, job, group and organization) and proposes Person-Environment (PE) fit as the main guiding mechanism for personality trait change at work. Drawing on this model, we develop a predictive framework of work demands that influence personality and outline eight core questions to advance this field.
