||Despite the widespread use of temporary workers in all types of organizations, their work experiences and behaviors have not been comprehensively studied. This study investigated temporary workers' perceived interactional justice and stigmatization by workplace permanent employees. It further explored their identification with important organizational targets including their temporary help service agencies, immediate work groups, jobs, and workplace organizations. Moreover, the study examined whether these concepts related to their engagement in beneficial and harmful behaviors in the workplace. The results show that the majority of the temporary workers perceived positive interactional justice, and the majority did not perceive being stigmatized by regular employees. The temporary workers identified more with their immediate work groups, jobs and workplace organizations than with their temporary help service agencies. Moreover, those temporary workers who identified with their immediate work groups tended to engage in beneficial behaviors beyond their duty, while they tended not to engage in harmful behaviors. In addition, the research revealed that many of the temporary workers reported task-related experiences as their positive experiences, while the majority of their negative experiences involved social and communicative aspects.
