Using self-reported data from 300 hospitality industry employees, proposed research questions were investigated using structural equation modeling. The findings indicate that supervisor and co-worker support have a significant effect on job performance. However, there was no significant relationship between perceived organizational support and job performance. The current study also showed that occupational commitment partially mediated the relationship between perceived co-worker support and extra-role job performance.enginfo:eu-repo/semantics/closedAccessOrganizational supportsupervisory supportco-worker supportjob performanceoccupational commitmentarticle303379389000484403900007
