Self-inconsistency or self-expansion from wearing multiple hats? The daily effects of enacting multiple professional identities on work meaningfulness.
研究身兼多职者日常扮演多重职业身份如何通过刺激感和自我疏离感两条路径影响工作意义感，并考察身份对比的调节作用。
-concurrently performing more than one job-and spend time enacting their professional identities each day. In accordance with self-consistency theory, scholars have emphasized that having to act out more than one professional identity promotes a fragmented sense of self for multiple jobholders, which impedes the meaningfulness of their work. However, we assert that this prevailing view about self-inconsistency is incomplete and problematic because it overlooks consideration for how enacting multiple professional identities may be a self-expanding and stimulating experience that satisfies basic needs for growth and exploration. By jointly applying self-expansion theory and self-consistency theory to the day-to-day experience of wearing multiple hats, we unpack how and why enacting multiple professional identities has countervailing implications for work meaningfulness through its effects on stimulation and self-alienation. We also consider the moderating role of identity contrast on these pathways to meaningfulness. We investigate our assertions in a series of preregistered studies-a comprehensive test of our model in a 15-day experience sampling study (Study 1) as well as constructive replications of each stage of our model (Study 2). Overall, we offer novel insights about the day-to-day tension between stimulation and self-alienation for people who act out multiple professional identities and the impact on the meaningfulness of their work.
