Daily uncertainty may overshadow the role of perceived manager effectiveness on daily performance via experienced daily positive affect: A multilevel study.

Objectives: In this study, we expand on the existing work on daily performance by focusing on (1) within-person fluctuation in perceived manager effectiveness in relation to daily positive affective experiences and daily performance and (2) between-person fluctuations in uncertainty as a relevant boundary condition of these relationships.

Methods: Multilevel data from 101 managers (1,010 measurement occasions) were used to test the hypotheses.

Results: The results showed that fluctuations in the perception of a manager's effectiveness related positively to daily positive affective experiences, and this relationship was moderated by the team member's uncertainty levels in such a way that perceived uncertainty buffered the positive effect of leadership effectiveness on positive affective experiences. Further, the findings evidenced a positive association between daily positive affective experiences and daily performance. Finally, results showed a significant indirect effect from perceived manager's effectiveness to daily fluctuations in performance via daily fluctuations in positive affective experiences.

Conclusions: Perceived manager's effectiveness made employees feel more positive affective experiences, which contributed to their daily performance. However, uncertainty overshadows the influence of a manager's effectiveness on their workers' positive affective experiences. We discuss implications for theory and practice.
