Purpose – This empirical study explored how coworker incivility and customer incivility affect the work engagement and job performance of frontline employees. Design/methodology/approach – To investigate the incivility and characteristics of hospitality industry workplaces, this study recruited frontline employees from tourist hotels as study participants. Because complete contact information could not be obtained for this population, convenience sampling was employed. A structured questionnaire was used for data collection. Findings – Coworker incivility and customer incivility reduced work engagement and job performance. The effects of coworker incivility on the work engagement and job performance are greater than those of customer incivility. Furthermore, work engagement has a positive effect on the job performance. Originality/value – Although studies have investigated the effects of customer incivility, these effects have not been compared with those of coworker incivility. Moreover, studies on the influence of coworker and customer incivility on job performance and work engagement in the hospitality industry and on those of work engagement on job performance have been scant. The current empirical study investigated the effects of coworker and customer incivility on the job performance and work engagement and of frontline hospitality employees
