Based on job embeddedness and resource conservation theories, the purpose of this study is to examine how internal job satisfaction mediates the relationship between job embeddedness and sales performance among financial salespeople. We propose a hypothetical model and examine the path difference between financial salespeople with low and high network abilities. The results indicate that internal job satisfaction mediates the relationship between on- and off-the-job embeddedness and sales performance. Both on- and off-the- job embeddedness can also determine the internal job satisfaction associated with improving sales performance among personnel with high network ability. The findings also identify further potential benefits when strengthening job embeddedness.
