Abstract
Previous major studies on work engagement have examined it based on the frame of the JD-R
model as a antecedent factor. This study points out some problems with the JD-R model, and examines
and analyzes its impact on work engagement by taking both quantitative management of work, such as
management of working hours, and qualitative management of work with the aid of job characteristics
theory. The results of this study confirm that the quantitative and qualitative management of work has
a positive impact on work engagement. In order to improve workers' work engagement, it is necessary
not only to manage working hours but also to devise ways to improve the quality of work.
