Abstract

This study explored the correlation between job characteristics and job stress with K pharmaceutical company’s staff, through a mediation model and path model of job ethics and job engagement. To this end, data were collected from 366 out of 370 survey responses. The survey consisted of four scales measuring the following: job characteristics, job stress, job ethics, and job engagement. The results were analyzed by the SPSS 22.0 program. Bootstrapping methods were used by the author to verify the average and standard deviation of variables, and to create the mediation model of how job characteristics relate to job stress, job ethics, and job engagement. In the current study, Cronbach’s alpha was calculated, and the values of the scales were .825 for job characteristics, .896 for job stress, .796 for job satisfaction, .830 for job ethics, and .924 for job engagement. For the research results, this study presented descriptive statistics for each variable of respondents and conducted a correlation analysis between job characteristics and job stress in relation to job ethics and job engagement (β=-.063, C.I[-.103~-.031]), job ethics (β=.080, C.I[.032~.137]), job engagement (β=-.253, C.I[-.323~.185]), and job characteristics and job stress alone (β=-.226, C.I[-.312~-.140]). Furthermore, the path model showed significant relationships among job characteristics, job stress, job satisfaction, job ethics, and job engagement. The mediation analysis revealed that there were meaningful correlations among job characteristics, job stress, job satisfaction, job ethics, and job engagement in K pharmaceutical company’s staff.
