The culture of an organization affects the way in which people behave and has to be considered as a contingency factor in any programme for developing organizations and HR policies and practices (Armstrong, 2009).
According to Armstrong, (2006), Organizational or organizational culture is a collection of values, norms, opinions, behaviors, and assumptions that, while not expressed, shape how people act and how things are done. Values are beliefs about what is essential about how individuals and organizations act. The unwritten laws of behavior are known as norms.
