Aim: Many care workers work with great stress and discontent at their workplaces due to various factors. Their stress induces burnout and turnover. This study aimed to examine physical, mental, wage-treatment, and human relationship stress factors in care workers from the view point of their sex, age group, number of years of experience, care environment, employment form, and care qualification.

Materials and Methods: We collected data from 351 persons (82 male and 269 female) on their stress in nursing care labor to analyze their stress degree with respect to concrete stress factors. 

Results: Regardless of their sex, many care workers were found to experience stress and dissatisfaction in terms of physical, mental, and wage-treatment. Greater stress was experienced by care workers in the age group 30-50 years than those aged >60, by those in the nursing homes service than those in the home visit service for the physical stress, and by those in the age group 20-40 than those aged >60 for the mental stress. There was very little stress in the human relationship factor. Regardless of sex, many care workers experience stress and dissatisfaction in terms of physical, mental, and wage-treatment factors except for human relationships.
