Resumen
Organizational restructuring and technological developments have been associated with working for longer hours, assuming more responsibilities, and feeling more pressure to reach demanding work targets leading to work intensification. Guided by the framework of the JD Resources and stress-as-offense-to-self theory, the aim of the present study was to explore how work intensification decreases work engagement. We posit that illegitimate tasks and work?family conflict could play a mediator role between work intensification and work engagement. A total of 480 employees in Portugal completed an online survey. The results showed a negative correlation between work intensification, illegitimate tasks, and work?family conflict. Work identification can affect work engagement indirectly through two paths: the separate intermediary effect of illegitimate tasks or work?family conflict and the continuous mediating role of illegitimate tasks and work?family conflict. The results indicate that work intensification decreases work engagement through the role of illegitimate tasks and work?family conflict. This study contributes to the literature on the impacts of work intensification by considering the sequential mediating effect of illegitimate tasks and work?family conflict on work engagement. Although past research has claimed that work intensification negatively impacts work engagement, our results showed that illegitimate tasks and work?family conflict play a critical role in this process.
