This research focuses on burnout as a driver of turnover intention amongst IT professionals. We extend Moore's exhaustion model by including further dimensions of burnout into the model, namely depersonalization and reduced personal accomplishment. The effect of stressors on these dimensions and the original dimension of emotional exhaustion is investigated, as is their influence on turnover intention among IT professional. Results based on a data sample of 154 IT professionals show that not only emotional exhaustion but also depersonalization leads to turnover intention. This outcome cannot be neglected when trying to reduce turnover intention in an organization in order to maintain competitive advantages. Moreover, while the stressors suggested by Moore influence emotional exhaustion, they only slightly explain the dimensions of depersonalization and reduced personal accomplishment. This indicates that these two dimensions of burnout are caused by additional factors, which represents a research gap worth investigating in future research.
