ABSTRACT

Purpose - This study aims to determine the factors impact on job stress of middle

manager in Vietnam and examine how effect of job stress on job performance of people

who get stress at work. A quantitative research design with a sample of 151 valid

respondents was employed. To test reliability and validity of variables, Cronbach’s Alpha

and EFA were applied. Multiple linear regression method was conducted to test the

hypotheses that were described on research model. One-Way ANOVA was used to test the

impact of demographic variables on job stress of middle managers in Vietnam.

Findings - the results have showed that four independent factors which are work

overload, conflict at work, lack of support and unfavorable work environment have

positively impact on job stress. The factor of work overload has strongest effect on job

stress; the second is conflict at work; the third are lack of support and unfavorable work

environment factors have nearly the same impact on job stress. The results also indicated

that job stress has negatively effect on job performance. Finally, the ANOVA testing

results have pointed out that gender and marital status have no difference effect on job

stress. Whereas management experience and age have different level of influence on job

stress of middle managers in Vietnam.

Key words: Middle managers, Job stress, Job performance, Work overload, Conflict at

Work, Lack of support, Work environment
