Organisational culture plays a very important role in organisations. Understanding the essence of the culture of an organisation and its values will facilitate the adaptation of the organisations in a time of global economy and turbulent economic environment and more important, the improvement of employees satisfaction. Maslow taught us that employees won't be highly effective or self-directed while they are disturbed by survival, security and socialization issues. There is a direct link between the organizational culture, employee satisfaction and between customer satisfaction and improved financial performance. Employee satisfaction is affected by a number of things, including working conditions, co-workers, pay, customers, etc. The way to improve employee satisfaction is always a challenge, and organisational culture is a main way to improve it.
