Abstract

This study investigated the association between leave use and improvement of work functioning impairment affecting presenteeism. A prospective, observational study was conducted among 5752 employees in a single corporate group in Japan to analyze the number of days of leave taken over a 1-year period and changes in work functioning impairment. As the number of leave days increased, work functioning impairment improved significantly. These results suggest that allowing employees to take more leave significantly contributes to improving work functioning impairment. Companies need to promote appropriate leave use to improve employee health and overall work productivity.
