For the analysis of work stress based on age, it affected older workerswith a value of p = 0.004, while based on gender, it affected the female workers with a value of p =0.001, based on years service, it had effect on long service years with a value of p = 0.018 and basedon sleep quality, it affected on poor sleep quality with a value of p = 0.003. The results of multivariateanalysis showed that work stress affected the productivity with a value of p = 0.001 (p <0.05) withgender and sleep quality as variable controls.
