Abstract

OBJECTIVES
To identify changes in relationships with superiors or colleagues at work and family members and social networks at home, based on occupational stress and psychological characteristics in during the process of restructuring some plants undergoing a long-term labor dispute.
METHODS
This study invested 213 workers involved in a long-term labor dispute using the KOSS (Korean Occupational Stress Scale) and the MMPI-2 (Minnesota Multiphasic Personality Inventory) and questionnaires. The KOSS and MMPI-2 scores in accordance with aggressiveness of trade union activity and changes in human relationships were compared. In addition, the odds ratio of whether there were differences in health behavior (perception of health status, smoking, alcohol abuse, medical treatment) and the absenteeism rate was calculated by logistic regression analysis.
RESULTS
For members of the aggressiveness of trade union activity group, the rate at which the relationship between superiors or colleagues deteriorated was high, as was the total KOSS score, occupational system and lack of reward score of KOSS subclass. The depression subclass score of MMPI-2 was generally high, while the score of hypochondriasis, hysteria, psychopathic deviate, hypomania was high, and social introversion was low in the active group. In cases in which there were high score of psychopathic deviate, hypomania and paranoia, there were also signs of negative health behavior.
CONCLUSIONS
Occupational stress caused by a long-term labor dispute, accompanied with depression can result in an aggressive, hostile and vulnerable personalities and have a negative impact on health behavior.
