XYZ JF PRIVIET MULTIDISCIPLINARY JOURNAL YR 2026 VO 1 IS 1 SP 31-39 DO 10.55942/pmj.v1i1.83 AB This study examines the effects of job stress and work motivation on employee performance at PT. XYZ is a private company operating in Jakarta, Indonesia. Increasing competitive pressures in the corporate landscape have heightened the importance of understanding the behavioral and psychological factors that drive productive employee outputs. Employing a quantitative, explanatory research design, data were collected from 30 permanent employees using a structured Likert-scale questionnaire. Validity and reliability tests using Pearson’s bivariate correlation and Cronbach's alpha confirmed the soundness of all measurement instruments (α > 0.70). Classical assumption tests, including normality (Shapiro-Wilk sig. = 0.827), multicollinearity (VIF = 1.420), and heteroscedasticity (Spearman's rho sig. > 0.05), indicating that the regression assumptions were met. Multiple linear regression analysis yielded the regression equation Y = 2.033 + 0.407X1 + 0.138X2, where X1 represents work motivation and X2 represents job stress. The results revealed that work motivation had a significant positive partial effect on employee performance (t = 3.564, p = 0.001), whereas job stress did not exhibit a significant partial effect (t = 1.245, p = 0.224). Simultaneously, however, both variables exerted a significant joint influence on employee performance (F = 13.539, p < 0.001), explaining 50.1% of the variance (R² = 0.501). These findings underscore the primacy of work motivation as a driver of individual performance outcomes and suggest that organizations should prioritize a motivational climate and supportive leadership to enhance productivity. The practical implications for human resource management in Indonesian enterprises are discussed, along with recommendations for future research using larger and more diverse samples.
