Analyses were performed with Rosenberg Self-esteem Scale. The population was 1,391 Korean workers in total. Subjects who get scores of self-esteem lower than those before the accidents were 539 people(42.34%). On the other hand, subjects who get the same or higher scores of self-esteem than those before the accidents were 802 people(57.66%). The average score of the whole showed 30.09 point that is higher than 29.99 points that were analyzed from primary panel data. The odds ratio of self-esteem is analyzed to find that what is the most important factor for improving self-esteem of the workers group. The result of odds ratio analysis was 1.60 in the not-to-return-to-work group, significantly higher of the score of self-esteem than the return-to-work group. The statistically significant odds ratio of unemployed workers group from the group of workers who return to work prove the academically conventional social norms. This result shows that the workers condition, whether or not they can return to their work, affects the workers‘ self-esteem. Therefore, the workers' condition for returning to the work should be considered the most important service for Korean workers' compensation and welfare services.
