The Job Characteristics Model (JCM) by Hackman and Oldham (1980) has been criticized for being culturally bounded. The moderators in the JCM have received weak support in the literature. Objectives of this study include: (1) to test the JCM using sample of 96 male Saudi employees from Saudi Aramco Company; (2) to investigate the moderator effects of power distance, uncertainty avoidance, individualism, masculinity, and exposure to foreign supervision on the JCM; (3) to assess differences between Saudi workers supervised by Saudies and their counterparts supervised by Americans with regard to their job satisfaction, organizational commitment, and job involvement; and (4) to evaluate the relationships between job satisfaction and organizational commitment and job involvement;Results of this study provide modest support for the JCM. Two moderators, individualism and exposure to foreign supervision, moderate the relationship between the job characteristics and knowledge of results. No significant differences were found between employees supervised by Saudies and their counterparts supervised by Americans. A significant relationship was found between general job satisfaction and organizational commitment, as well as between internal motivation and job involvement;Finally, the results of this study are discussed in comparison to the findings of previous studies and further research is recommended.
