The COVID – 19 outbreaks have been changing the world dramatically in many ways, including the way we work. As a result, the Working-from-home (WFH) trend explodes rapidly and gradually develops into a permanent solution. This study aims to evaluate the willingness to continue WFH in the long term by analyzing the relationship of perceived person and environment to the perceived person-environment fit. A research framework was developed based on the Person-Environment Fit theory with six combinations of Demands-Abilities and Needs-Supplies to examine the Perceived Person-Environment Fit, which eventually used to anticipate the willingness to continue WFH. The research was conducted mainly in Vietnam, with 305 employees’ answers were collected. A mixed-use of SPSS and SmartPLS was utilized to analyze the data by quantitative approach. The research indicated that when there is an excess in both persons’ and environments’ expectations, there will be an increase in Perceived P-E fit, with the Perceived Fit of Lack of information and Perceived Fit of Facilitating Conditions playing more important roles. The Perceived P-E fit then was proved to positively affect the Continuance Intention to WFH, Job Performance, Job Satisfaction, and Work-life balance. Lastly, positive moderating roles of IT Capability and System Quality were also addressed along with the negative moderating effect of Extraversion characteristic.
