Based on the person-environment-fit theory, the purposes of this study are to explore: (1) the associations between person-environment-fit (fit of ideal working time and actual working time) and work results (well-being, job satisfaction and organizational commitment); and (2) the differential effects of individual characteristics(gender, age, marital status, child depend, education, and social status ) on the results of employees’ actual working time. Our analyses were based on data from 2005 Taiwan Social Change Survey (TSCS), using nationwide representative sample of 1,234 individuals with full-time and part-time jobs. We found that employees had more organizational commitment under the situation of ideal working time was higher than actual working time. Furthermore, multivariate confirmed that younger, living without dependent child and low social status employees preferred to have a flexible working time. It is thus recommended that organizations need to consider the individual preference and supply multiple options to employees. More importantly, the fit between personal needs and organizational supplies may also help organizations to achieve greater efficiency and better performance. Key words: person-environment-fit, ideal working time, actual working time, work results
