This paper studies the impact of social support from peers, supervisors, and the organization on job stress and job satisfaction. According to the previous studies, they have already offered evidence that stress can affect both physical and emotional responses, and social support would have some impact on job stress and job satisfaction. However, most of the studies focused on private sector companies, and it is rare to find a study focused on Macau. This paper has used governmental departments in Macau as a focus to test whether there is an impact of social support from peers, supervisors, and the organization on job stress and job satisfaction. The total sample of 100 respondents from 9 governmental departments in Macao was used to test which type of social support (from peers, supervisors, organization) would have the negative impact upon job stress, meanwhile, the current study would also test which type of social support (from peers, supervisors, organization) would also have the positive impact upon job satisfaction. The results indicated that social support from supervisors had a negatively influence to job stress; and social support from peers and organizations had a significant positive explanatory effect for job satisfaction. These results are consistent with some existing studies. In addition, the results of this study also identify a number of managerial implications, such as providing some information to Macau governmental departments on how to better arrange and allocate time and support for employees.
