This paper contributes to the literature by examining xenophobia among tourism employees and its relationship with service sabotage, which was not previously explored. Two studies were conducted. A survey study is conducted with 194 frontline employees working in tourism, and 297 tourists participated in an experimental setting. Based on the findings, xenophobia mediates between employee community attachment and service sabotage, with the employees' moral identity and emotional regulation influencing this relationship. Furthermore, tourists' desire for revenge when experiencing service sabotage is both directly and indirectly affected by cultural differences attributions and discrimination attributions. Notably, if tourists attribute the sabotage to xenophobia, their desire for revenge against the firm is diminished. This research enhances our understanding of the complex dynamics between xenophobia among frontline employees, service sabotage, and customer retaliation in the tourism.
