How does social media use in the workplace affect employee voice? Uncovering the mediation effects of social identity and contingency role of job-social media fit
通过对348名中国员工的调查，发现工作场所社交媒体使用通过社会认同影响员工建言，其中组织认同促进建言，关系认同促进促进性建言但抑制抑制性建言，且工作-社交媒体匹配调节这一过程。
Purpose Employee voice is crucial for organizations to identify problems and make timely adjustments. However, promoting voice in organizations is challenging. This study aims to investigate how social media use (SMU) in the workplace affects employee voice by examining its intrinsic mechanisms and boundary conditions. Specifically, this study examines the mediating roles of social identifications and the moderating effects of job-social media fit on the relationship between SMU and social identifications. Design/methodology/approach This study conducted a survey of 348 employees in China. Findings First, SMU affects voice through social identifications. Second, distinct identifications have different effects on voice, such that organizational identification positively affects employee voice, while relational identification positively affects promotive voice and negatively affects prohibitive voice. Third, when social media is highly suitable for the job, the positive effect of work-related SMU on organizational identification is strengthened, while the positive effect of social-related SMU on organizational identification is weakened. Originality/value The results indicate that different identifications have distinct impacts on voice. Additionally, this study reveals a double-edged sword effect of SMU on voice through different social identifications. Further, job-social media fit moderates the relationship between SMU and social identifications. These findings have important implications for organizations adopting social media.
