In order to ensure high-qualified employees who come into direct contact with participants, in particular there must be a thorough understanding of the job environment. Therefore, this study aims to explore the job environmental factors of the convention organization which are associated with employee`s job satisfaction and identify job environment-related factors affecting employees` organizational commitment and turnover intention. To examine the effects of job environmental factors of convention organization on organizational commitment and turnover intention, structural equation modeling (SEM) was established and employed. This research shows that several factors related to the job environment of convention organizers affect their organizational commitment and indirect effects on turnover intention. The results support that the leader`s role is very important for creating organizational loyalty, the salary system must be fair and equitable to increase long-term committed employees and a systemized and pleasant working environment is a critical factor for building normative and continuous commitment - CEOs should pay much more attention to this aspect than they do currently. To relieve PCOs` turnover intention, CEOs should focus on the development of a strategic physical and institutional environment that has a positive influence on employees` continuous commitment.
