Gambling is the most viable and sustainable economic development option for many travel destinations and in some countries, gambling is a major economic sector. Gambling is a multibillion dollar business that continues to grow at an exponential rate each year in many countries around the world. However, the rapid growth of gambling poses great challenges for destination operators to maintain workers' positive workplace attitudes and behaviors. This study examines the effects of psychological contract breach (PCB) on the work-related attitudes and behaviors of casino dealers and explores the moderating role of leader-member exchange (LMX) on these relationships. This study also compares the effect of PCB on the turnover intentions of dealers in VIP rooms and mass tables. The findings indicate that: (1) dealers' perceived PCB is negatively related to their work-related attitudes but positively related to turnover intentions; (2) LMX partially moderates the effects of PCB on work related attitudes; and (3) PCB is associated more with turnover intentions of casino dealers who work in the VIP gambling rooms than with those who work at the mass tables. These results offer valuable insights for casino operators to promote managerial efficiency in the workplace.
