THE RELATIONSHIP BETWEEN WORKLOAD AND JOB STRESS AMONG SHIFT WORKERS AT PT MITRA ADI PERKASA

Abstract

This study aims to analyze the relationship between workload and job stress among shift workers at PT Mitra Adi Perkasa, one of Indonesia's largest retail companies. The research employed a quantitative approach with primary data collected through questionnaires distributed to 80 shift workers using saturated sampling technique. Data analysis was conducted using SPSS 27, including validity and reliability tests, classical assumption tests, simple linear regression analysis, and hypothesis testing (t-test). The results revealed that workload among shift workers was categorized as high (mean = 3.95), with service demands and time pressure being the most prominent indicators. Job stress was also categorized as high (mean = 3.88), with sleep disturbances and work-family conflict as the most significant indicators. The hypothesis test demonstrated a significant positive relationship between workload and job stress (t-value = 11.000 > t-table = 1.990; sig. = 0.000 < 0.05), with a regression coefficient of 0.748, indicating that each unit increase in workload leads to a 0.748 unit increase in job stress. The R Square value of 0.607 suggests that 60.7% of job stress variance can be explained by workload. These findings emphasize the importance of effective workload management strategies to reduce stress levels and improve employee well-being in shift work environments.
