Stacking bricks or building a cathedral? How affective shifts shape perceptions of daily task significance

One of the most fundamental experiences of deriving positive meaning from work stems from perceptions of task significance. Although interactions with managers and beneficiaries can provide inspirational cues that make the significance of employees' work tasks salient (Grant, 2012, 2008), relying solely on an understanding of these discrete experiences may limit an employee's ability to consistently perceive the significance of work tasks from day to day. To expand understanding of the influences that shape perceptions of daily task significance, we draw on personality systems interaction theory (Kuhl, 2000) to examine the influence of affective shifts. Using a daily diary design over 10 workdays, results from 292 daily observations nested within 38 employees showed that upshifts in positive affect and downshifts in negative affect were positively related to daily task significance. In turn, daily task significance was positively related to helping behaviors and negatively related to work withdrawal. Daily task significance also exhibited an indirect effect on the subsequent workday's start-of-day mood. Employees who perceived high significance today were more likely to start tomorrow off with lower negative mood due to higher helping behaviors the day before and with lower positive mood due to lower work withdrawal the day before. The results yield new insights into the experience of daily task significance and offer significant implications for theory and practice on affect, task significance, and work performance.
