Daily job crafting as trait expression: Big Five personality activated by emotional demands

Abstract Purpose This study investigates how trait-level personality differences and day-level situational demands jointly shape proactive work behaviors in the form of job crafting. Building on Trait Activation Theory, we argue that emotional demands in the workplace function as trait-relevant situational cues that make stable personality differences more behaviorally salient in daily job crafting behavior. Drawing on Density Distribution reasoning as a conceptual lens, we further note that stable traits can coexist with meaningful daily variability in behavior across days. Originality Although the Big Five personality traits are well-established predictors of workplace behavior, relatively little is known about how their effects vary in response daily situational demands. Design/methodology The study followed a daily diary design with 1884 observations nested in 157 doctors from different hospitals. We employed multilevel modelling in MPLUS to disentangle within-person and between-person effects. Findings The findings showed that openness, conscientiousness, extraversion and agreeability were positively associated to average daily job crafting, whereas neuroticism was negatively associated. Cross-level interactions further revealed that openness, extraversion and conscientiousness strengthened the positive relationship between daily emotional demands and job crafting, whereas neuroticism attenuated this relationship. Implications These results highlight the value of integrating a stable traits perspective with daily behavioral variability to better understand when personality differences are most visible at work.
