Reverse culture shock is the emotional and psychological distress suffered by some people when they return home after a number of years overseas. This can result in unexpected difficulty in readjusting to the culture and values of the home country, now that the previously familiar has become unfamiliar.

In a business context, the advent of globalization has resulted in more and more employees being sent on lengthy assignments to other countries. With the number of expatriates who live and work in countries other than their own having increased in recent years, reverse culture shock is a phenomenon that is on the rise.
