Article 657(2) (Exclusivity of Rights and Duties), Civil Act, as last amended by Act No. 12881, Dec 30, 2014

An employer has a right of personnel deployment. As long as the order is justifiable, it is possible for an employee to go to a business trip abroad. However, when an employer wants to send an expatriate worker for a long time, then there needs to be managerial necessity and consent from the applicable employee.

The employer should be the same even if an employee performs tasks outside the country.
