Expatriates are employees sent by organizations to work in other countries on long- or short-term projects to help establish operations overseas, enter new markets, and transfer skills. Expatriates face cultural shock, loneliness, language barriers, and relationship issues abroad. Human resource management can help through cross-cultural training focusing on awareness, knowledge, and skills to prepare expatriates and their families for living in another culture and ease the adaptation process. It is also important to help employees when they return home through repatriation courses that address reverse culture shock and social and financial adjustments.
