The measuring tool that researcher used are Job Stress Scale for job stress consist of 4 dimensions (job stress scale, role expectation conflict, co-worker support and work-life balance) and 22 items as totals and measuring tool for job demand using Challenge- and Hindrance-Related Self-Reported Stress Measures consist of 2 dimensions (challenge stressors and hindrance stressors) and 11 items as totals. Job stress scale using Likert scale from 1 (Strongly Disagree) to 6 (Strongly agree) for job stress scale, role expectation conflict and work-life balance dimensions. Co-worker support dimension using Likert scale from 1 (never) to 6 (all the time). The scale for Challenge- and Hindrance-Related Self-Reported Stress Measures also using Likert scale from 1 (produces no stress) to 5 (produces a great deal of stress). The design of this research is quantitative by using correlation analysis using Pearson correlation coefficient in SPSS.
