The result shows that 4 of the independent variables which are work relationship, work overload, job security, and job characteristics are unable to be processed due to validity and reliability problem. On the other hand, 4 other variables which are work-life balance, resources and communication, job control, and pay and benefits passed the validity and reliability test. All 4 variables also passed the classical assumption test and continued to Multiple Linear Regression method with the SPSS application. The result

shows that all of the independent variables do not have significant impact towards the dependent variable. The research was able to determine that neither of the independent variables have significant impact towards dependent variable simultaneously. Then, the result of this research was unable to determine which variable give the most impact towards the job stress. There are several limitations of this research that the writer encounters First is lack of supervision in gathering data. The lack of supervision and direct instruction to the respondent during the process made some of the data become invalid and unreliable. Second is limited coverage of research. This research was focused only on one department which is Housekeeping department. The result of this research can only represent the condition of the department and cannot give a better representation of the condition in the company as a whole. Third is limited number of measurement item for independent variables. The indicators used for each variable are only 3 items which might make the result become unsatisfying. The problem with limited item of measurement makes the choice and input from the respondents become limited thus making the most of the validity and reliability test of several independent variables are not up to standard. Considering the limitation of this research, writer believes the research can be improved to yield better and accurate result. First is to increase the number of indicators for independent variables. Future research can give more indicators in the instrument of research in order to gain more accuracy in measuring the data. A greater number of indicators will be able to help the data distribution and avoid any bias result from the respondents. Second is to expand the coverage of research. This research is limited to the Housekeeping department in Hotel ABC. Future research can cover more departments in the industry such as Food and Beverage or Front Office department. Third is to give direct instruction to the respondents. To avoid confusion from the respondents in answering the questionnaire, it is recommended for the researcher to give instruction and explanation of each indicator to the respondents. Fourth is to add new variable to the research. Future research can include new variable to give better analysis. The recommended variable to be added is Job Satisfaction. Job Satisfaction is often used in the past research as a complement to the Job Stress to find the condition of the employees within the company. Adding this variable will be beneficial for the researcher and company as it will give more accuracy in explaining the employees’ mental health
