Seeking challenges, individual adaptability and career growth in the relationship between workload and contextual performance: A two-wave study

Based on the theoretical approach of the psychology of sustainability and sustainable development and on the theoretical Job Demands-Resources model, this contribution aims to explore the mediating effect of seeking challenges on the relationship between workload and contextual performance and the moderating effects of individual adaptability and organizational career growth in this process. The study involved a convenience sample from different occupational sectors. Data from 178 employees were collected with a self-report questionnaire administered at times T1 and T2 (six months later) and then analyzed through conditional process analysis. Challenging job demands (T1) fully mediated the relationship between workload (T1) and contextual performance (T2); furthermore, individual adaptability (T1) moderated the relationship between workload (T1) and challenging job demands (T1), and organizational career growth (T2) moderated the relationship between challenging job demands (T1) and contextual performance (T2). The results imply that seeking challenges can represent an effective approach to promote sustainable development through improvement of performance at work, maintaining its sustainability over time. The present study is innovative because in the new framework of the psychology of sustainability and sustainable development is able to link workload, seeking challenges, career growth and performance in a two-wave study that not only has theoretical implications for organizations but also operative and practical spillovers.
