Workforce management is a problem in many islands. Although the Jeju tourism department and local business offer attractive promotions and opportunities, due to the demands faced by tourism professionals, many have left their positions in Jeju and returned to the mainland Korean peninsula. The purpose of this study is to explore the motivations, career decisions, and turnover behaviours of a group of former tourism professionals who had previously worked in Jeju for a period of less than two years. Based on social cognitive career and motivation theory, the study was guided by two research questions: 1) Why did the participants leave their positions in Jeju after less than two years of career development? and 2) How did the participants describe their working and living experiences in Jeju as professional tourism workers? The data from 42 participants indicated that overloaded responsibilities and unbalanced schedule, financial consideration, and personal consideration were the three major reasons for leaving Jeju. This study aims to help local businesses and governments to understand employees’ motivations, career decisions, and turnover behaviours. Further, this research seeks fill gaps in the literature regarding workforce shortages and tourism management for islands and remote regions, particularly in East Asia.
