直銷工作一向被定位為實現自由創業與致富夢想，但不是每個人都會成功。要經營出色的直銷商體系，一定要靠組織中其他成員相輔相成，將人際網路連結起來，然後透過人際關係來管理銷售體系。本研究探討直銷公司上線與下線之互動關係，即組織公平與領導－成員交換關係及個別直銷商之人格特質，會如何影響經營型直銷商的工作滿足度。本研究結果發現：(1)下線之人格特質越偏向親和性、外向性，就會越加強其組織公平認同度、領導－成員交換關係及工作滿足度，而人格特質越偏向情緒敏感性就會越減弱其組織公平認同度、領導－成員交換關係及工作滿足度；(2)下線對於組織公平有越佳的認同，會提高與上線之領導－成員交換關係；(3)下線對於組織公平及領導－成員交換關係有越佳的認同，會增加下線的工作滿足度。
