Abstract
Determining factors for adaptation to a new workplace in light of 3 cases that have taken early retirement due to occupational maladjustment are discussed. The character traits of these 3 cases are regarded as individual factors because of their conspicuousness. In regard to adaptation to new workplaces, two of my cases were unable to adapt in their previous workplaces because of their avoidant personality. They were also unable to adjust to their present workplaces. When the worker's character traits tend to cause occupational maladjustment, appropriate approaches including counseling and occupational adjustment should be recommended to the worker.
