With the ongoing internationalization, the demand for employees with international orientation and experience is growing. Not only executives are affected by assignments abroad, but also specialists and junior staff. High expectations of expatriates require a great deal of flexibility and sensitivity to overcome professional hurdles and various life adjustments. Returning home after assignments abroad does not always meet the expectations of returnees and can cause problems both professionally and socially. However, employees bring valuable experiences, new ideas, and intercultural competencies that companies can leverage as a source of innovation and creativity. To harness this potential, returnees need professional support for their reintegration. The book examines the reintegration of employees.
