Frontline power grid workers are always facing plenty of stressors such as aerial work and high job demands, which may lead them to be less satisfied with their job. Therefore, this study aims to investigate frontline power grid workers' job satisfaction (JS) and explore how it can be improved by its relationship with personality traits and work-family support (WFS). Data from 535 frontline power grid workers were collected from two power supply bureaus in Guangdong Province, China. Structural equation modeling (SEM) was adopted to examine the structural relationship between personality traits taken as independent variables, JS as dependent variable, and WFS as mediator. The bootstrap method was used to test the significance of indirect effects. Results suggested the overall job satisfaction of our sample is 3.34 ± 0.55 on a scale ranging from 1 to 5, and significantly correlated with personality traits and WFS. Moreover, the results of SEM and bootstrap indicated that WFS partially mediates the effect of neuroticism on JS and fully mediates the effect of conscientiousness and extraversion on JS. These findings shed light on how personality traits and environmental factors jointly impact JS and highlight the important role of WFS among frontline power grid workers.
一线电网工作人员经常面临许多压力源，如高空作业和高工作要求，这可能导致他们对工作的满意度降低。因此，本研究旨在调查一线电网工作人员的工作满意度（JS），并探讨其与人格特质和工作-家庭支持（WFS）的关系如何提高工作满意度。本研究从中国广东省的两个供电局收集了 535 名一线电网工作人员的数据。采用结构方程模型（SEM）检验人格特质作为自变量、工作满意度作为因变量、工作-家庭支持作为中介变量之间的结构关系。采用自举法检验间接效应的显著性。结果表明，我们样本的整体工作满意度在 1 到 5 的范围内为 3.34±0.55，与人格特质和 WFS 显著相关。此外，SEM 和自举法的结果表明，WFS 部分中介神经质对 JS 的影响，完全中介尽责性和外向性对 JS 的影响。这些发现揭示了人格特质和环境因素如何共同影响工作满意度，并强调了工作-家庭支持在一线电网工作人员中的重要作用。
