In the field of Organizational Behavior, the area of job attitudes and behaviors are generally studied through job satisfaction. It was hardly studied through organization commitment and professional career commitment. The nursing department is generally the largest unit in healthcare organizations. Therefore, the attitudes and behaviors of nurses toward their job would effect the organization performance. The purpose ofthis research is to understand the responses of nurses.The study sample consisted of nurses in a teaching hospital. Questionnaires were developed to collect data on personal basic information (including sex, age, marital status, education level, license obtained, service unit, year of service, salary level, and etc.), attitudes toward organization commitment and attitudes toward professional career commitment. 600 questionnaires were administered, with 438 responded (response rate: 73%), and 395 effective responses (effective response rate: 65.8%). Data were codedand then analyzed through SAS program, including frequency, percentage, and co rrelation analysis. The results showed that nurses generally did well in organization commitment and professional career commitment. The areas that most of the nurses considered being important were the application, the involvement, the enhancement and the future development of professional job. Most of the study objects showed a large difference between the outside reputation of the organization and the personal expectation. Healthcare organization administrators should consider these study results whe n dealing with issues in human resource management and job planning.
