With the incremental introduction of a 40-hour-workweek system, quality of life and leisure have been increasingly attracting attention in our society. To keep pace with this change of the time, many Western countries have been implementing so-called ‘work-life balance’ policy, key topic in the area of human resources and organizational management for the 21st century. Therefore, this study was intended to review present situations of businesses and workers in Korea by measuring the work-life balance level of worker and corporate culture and thereby present basic materials for further studies on ‘work-life balance.’ For the purpose of examining the present situations of work-life balance, this study was conducted on the work-life balance level of individual workers and businesses separately. As a result, both individual workers and businesses were found to have poor work-life balance. Analysis of the relationship between worker’s work-life balance and productivity variables to test validity of work-life balance measuring items showed that work-life balance had an effect on many variables of productivity. Finally, ways how to use the findings from this study were discussed.
