• Over the last two decades, the multi-dimensional notion of job performance has been fully brought to life. The differentiation between core task performance and various aspects of discretionary work behaviour is flow commonly applied. A multitude of empirical studies, enhancing our knowledge of the antecedents and consequences of the different performance aspects, have recently been summarised through various meta-analyses. We use this as all occasion for taking stock in order to identify new areas of theorising and empirical research. Focusing in particular oil proactive performance aspects, the present paper identifies three themes that could inspire new research and model development. We suggest taking a new approach to the treatment of time in order to account for the dynamic nature of performance oil the one hand, and to consider life-span changes oil the other, developing comprehensive models oil proactivity-enhancing interventions, and more strongly incorporating a cross-cultural perspective.
