Following the 1973 rise in the price of oil, the six Gulf Cooperation Council (GCC) nations of the Middle East became hosts to hundreds of thousands of foreign workers taking part in the economic development of the region. From the beginning, the employment of migrant workers was seen as a temporary measure, necessary to compensate for the small indigenous populations in the Gulf. The numbers of foreign workers has become so great, that the migrants now constitute a majority of the population in several of the GCC countries. The relative permanence with which foreign workers have now established themselves is of great concern to the host governments. It appears that the insufficient skill-levels and sizes of the national workforces, together with the position the extensive and growing migrant communities hold in the growing Gulf economies point to the continued presence of large foreign populations for some time to come.

Individuals with different personal demographics and job-based factors have different attitudes and behaviors, which can influence their levels of commitment to their organizations. These differences in organizational commitment increase as their cultural backgrounds differ significantly. Personal demographics and job-related factors are reliable predictors of employees' commitment to their employing organizations. The purpose of this study was to empirically investigate if there is a difference in the level of employees' commitment to Saudi petrochemical companies on the basis of differences in their personal demographics and job-related factors.
