In recent years, the awareness of mental health is increasing in the industrial world. Some overwork suicide lawsuits of these days can be mentioned as its cause. The mental health management for employees will become to take more important part of business management in the future. The purpose of this paper is to analyze the various aspects of mental health of employees especially in relation to employee attitude and/or performance appraisals.
A company based survey that included engineers was conducted through the anonymous questionnaires on "mental health", "organizational commitment". "work motivation" and "work involvement". After comparative review of mental health and work motivation, it was found that work involvement and the internalization factor of organizational commitment give negative influence on mental health but positive influence on work motivation.
It can be interpreted that the concept of mental health should not be caught in the only context of work and organization. It is suggested that employees should work while they moderately commit to the organization in order to keep their mental health good. This is also supported by the findings of the other analysis that shows performance appraisals have no effect on mental health.
