When Does the Leader's Positive Expression Get a Positive Response From Members? The Three-Way Interaction Effects of Perceived Deep/Surface Acting, Positive Affect, and Quality of Leader-Member Exchange on Work Engagement.

Although researchers have argued that a leader's positive affective display effectively induces work motivation among members, it has not always resulted in desirable outcomes. This research addresses these critical issues and explains why individuals react differently, by considering the three-way interaction of the characteristics of expression, the positive affect of the members, and quality of leader-member exchange (LMX). To verify our hypotheses, 698days from 47 leaders and 146 members were collected through the Experience Sampling Method. The analysis was conducted using HLM, and the results showed that, for members with high quality LMX, the positive effect of perceived deep acting on work engagement was strengthened when positive affect was high, and the negative effect of perceived surface acting was weakened when positive affect was high. On the other hand, members with low-quality LMX showed a stronger positive effect of perceived deep acting on work engagement when positive affect was high, and the negative effect of perceived deep acting was mitigated when positive affect was low. These results demonstrate that quality of LMX serves as a context of the affective display between leaders and members, and the effect of displaying positive affect relies on members' perception of the characteristics of the expression and the affective state.

Daily Job Crafting Helps Those Who Help Themselves More: The Moderating Role of Job Autonomy and Leader Support.

Not all members are engaged in job crafting behavior in the same context, yet little research has addressed boundary conditions of daily job crafting. This study addresses these important issues and how the effects of daily job crafting vary depending on the work situation. We consider job autonomy and leader support as between-person level moderators and reveal how it affects the impact of daily job crafting on daily job satisfaction. Through the experience of the sampling method, we collected 946 days of data from 108 members (61.9% were male and 38.1% were female) for hypothesis testing. The analysis of results showed that the main effect of daily job crafting and the cross-level moderating effect of leader support were significant, and the moderating effect of job autonomy was not significant. In particular, the positive effect of daily job crafting on daily job satisfaction was strengthened for members with low leader support. These findings highlight that leader support is an important social context in job crafting, and provides insights when members can get more advantages from their daily job crafting.
