Hill wood Medical Centre staffs cooperative problemOrganizational cultures and subcultures will influence Hill wood Medical Centre organizational performance and commitments. The subcultures may take precedence over the organizational culture for individual employees and thus gain their commitment. Hill wood medical centre can therefore focus on the relationships of both organizational culture and subcultures to satisfy staffs need to serve patients in happy work environment. Organizational culture includes leadership style and job satisfactory measurement. Hence, employees' commitment was examined in relation to the level of consent to and conflict with managerial strategy. Although, managerial strategy is not the same as leadership, the attributes and skills required in leadership could be seen as an essential part of managerial strategy. Organization culture(s) has ( have) a causal modelling approach to examine the determinants of organizational commitment and labour turnover. Organization culture(s) can include a variety of variables, e.g. age, pre-employment expectations, perceived job characteristics and the consideration of leadership style, which all influence organizational commitment indirectly via effects on job satisfaction. I supposed that Hill Wood Medical Centre existed relationship of organizational culture and subcultures to influence staffs feel satisfactory and commitment. Also of interest is the relationship of these variables with leadership style, job satisfaction and subject characteristics, such as age, level of education to its staffs in this hospital. In Hill Wood Medical Centre organization, its organizational culture was the hospital cultures and subcultures which refer to the culture of the wards or work units or operation rooms to every department staff commitments refer to nurses team and medical service chief medical officer team and surgeons team and administrative department etc their different departments' individual staff's commitments. There is a culture relationship between this medical centre organization commitments and it was measured with administration department and operating rooms and wards department etc different departments' subcultures as well as surgeons and nurses and doctors and administration staffs etc different teams' subcultures. More specifically, it is expected that such as Hill Wood Medical Centre organizational culture could be more supportive and innovative to its different departments, such as wards and surgeons operating rooms and administrative office etc different departments subcultures. Thus, I believe there is a strong relationship between this medical centre organizational cultures and subcultures and commitment and characteristics of this organizational overall culture, such as corporate values and beliefs commitments and performance to Hill Wood Medical Centre organization.
