Not My Job, I Do Not Want to Do It: The Effect of Illegitimate Tasks on Work Disengagement

As a prevalent source of work stress, illegitimate tasks (IT) offend employees’ professional identity and threaten individual self-view, then create many negative organizational outcomes. However, current studies have paid inadequate attention to the impact of IT on work disengagement (WD) and its influencing path, failing to comprehensively identify the negative effects of illegitimate tasks. Based on stress-as-offense-to-self (SOS) theory and ego depletion (ED) theory, the influencing path of illegitimate tasks on WD is explored, and coworker emotional support (CES) and leisure crafting (LC) are introduced to explore the intervention conditions on the impact of illegitimate tasks. By analyzing data from a survey of 260 employees, this study reveals the following findings: illegitimate tasks have a significantly positive impact on work disengagement; ED fully transmits the positive impact of illegitimate tasks on work disengagement; CES and LC not only attenuate the effect of illegitimate tasks on ego depletion, but also negatively moderate the indirect effect of illegitimate tasks on work disengagement through ego depletion.
