After operate The National Health Insurance policy, every hospital focused in decreased cost to improve profit. The nursing staffs become the main target to lower staffing cost，so recruited the flexibility in nursing manpower followed. This study focuses to investigate a hospital how to utilize different working status nursing staffs and analysis they in organization commitment、job satisfaction and performance. The results are as follows：
The nursing staff's age mostly range between 21-25, mean working years is 6.45. In functional flexibility, the formal staff is the first member to transfer place. In number flexibility, the hospital recruited contingent workers to resolve the manpower shortage. In time flexibility, part-timers could fit the vacancy in manpower of numbers and some intervals times. Estimate the cost：the part-timers part could save about NT$ 2 million dollars per year, but the temporary-contract part paid more around NT$1 million dollars in recruitment.
The part-timers in moral commitment, calculative commitment, working condition and performance are below than the formal staffs. In educational level, the occupational staffs are higher than the university level staffs, but no different about job satisfaction. In married status, unmarried workers are lower than the married employees. Over 40 years old workers in many parts are higher than the 25-29 years old. More than 20 working years staffs compare with 3-5 years shows different results. The regression model exhibits formal staffs, higher supervisor ability and lower working condition then the working performance is high. Calculative commitment is different from many other parts. Total accident events and working status shows significant difference. The fall event and working status, age also have significant difference.
According to the above results, this study suggests the consideration about cost, when the hospital hire the contingent workers, it still need to provide enough on-job training opportunity and other relative procedures then could maximum the efficiency of the flexibility utilization in manpower.
