Since 1961, Thailand has pursued the National Economic and Social Development Plans which brought about the changing of development direction; from agricultural to industrial basis, in the continuing and increasing manner. The main activities of industrial-based development were to develop goods for export promotion, invite the foreign investment, as well as promote Thailand tourism. The activities were conducted under the managerial principles of industrial businesses, both in manufacturing and servicing features. Then, the activities could affect Thai people in agricultural sector by changing their working status, from self-employers to industrial-employed workers in different cultural work-circumstances. Those Thai people had to learn and adapt more to fit the new working culture. By the end of 2007, the major economic crisis, flown from the powerful United States of America, had the effect on trade and investment activities in Thailand. Hence, the development of organizational culture, concerning employee’s commitment, has been significant for organization’s stability.
