The Influence of Physical Workload, Mental Workload, and Shift Work on Employee Performance Through Job Stress as a Mediating Variable at Hotel Grand Bydiel Cianjur

Abstract

The hospitality industry requires readiness of human resources to deliver fast, accurate, and consistent service, so that job demands may increase the pressure experienced by employees. This study aims to analyze the effect of physical workload, mental workload, and shift work on employee performance through job stress as a mediating variable among employees of Hotel Grand Bydiel Cianjur. A quantitative method with a causal-associative approach was used, involving 109 employees selected through a saturated sampling technique. Data were analyzed using Structural Equation Modeling based on Partial Least Square (SEM-PLS) with SmartPLS 3. The results show that physical workload has a positive and significant effect on employee performance but no significant effect on job stress. Mental workload has a negative and significant effect on job stress but no significant effect on employee performance. Shift work has a positive and significant effect on both employee performance and job stress. Job stress has no significant effect on employee performance and does not mediate the effect of the three independent variables on employee performance. Hotel management is advised to continuously evaluate workload distribution, shift scheduling, and employee stress management.
