The present study drew from the social identity theory to explore
the workplace friendship and adopted the social support theory to examine the
effects of workplace friendship on affective commitment, helping behavior, as
well as turnover intention. Research subjects of this study were civil affairs
workers in Tainan and Chiayi County, Taiwan. Random sampling was used to
collect anonymous questionnaires. The results of structural equation modeling
(SEM) demonstrated that workplace friendship had positive influences on
affective commitment and helping behavior and a negative influence on turnover
intention. Prior research offered little empirical evidence of affective
commitment as a mediating mechanism linking the workplace friendship–helping
behavior and workplace friendship–turnover intention relationships. The present
study found that effective commitment played an important mediating role.
Implications for practice were discussed, and directions for future research
