The business environment, which significantly impacts companies, is changing daily. In this situation, they should change their work habits flexibly and adapt to the new environment to compete with their rivals. The global-mobility is one of the solutions, though since it brings not only diversity but also complication to the company, it is not easy to implement in the actual work field. For example, if the company plans to hire employees from different regions to gain diversification, the HR division must deal with their different work cultures and related laws. Otherwise, global-mobility causes conflicts or problems in the company.
