This study aims to determine the influence of social exchange relationships, leader’s political skills, job stress, job satisfaction, and organizational commitment on turnover intention among dental hospital hygienists.
A self-administrated questionnaire survey was conducted from April 1-May 12, 2020, involving 209 dental hospital hygienists in Seoul, Busan, and Gyeongnam. The collected data were analyzed using SPSS and AMOS statistical analysis programs.
In the hypotheses testing, 9 of 18 hypotheses were supported. In social exchange relationships, job stress, job satisfaction, and organizational commitment, the path to turnover intention had a significant effect, but it was not statistically significant in leader’s political skills. With regard to mediating effect, job stress, job satisfaction, and organizational commitment played a complete mediating role in the path from social exchange relationships to turnover intention.
To increase job satisfaction and organizational commitment, and lower job stress in order to have a positive impact on turnover intentions, it is imperative to develop and apply a program to enhance social exchange relationships.
