It's about how I have to behave in order to survive or feel good in this organization. This is the most pragmatic definition of organizational culture. It's beyond the manual. It is the life of the organization.
Maybe I need to sit back and mind my own business and just do what I’m told, maybe I should always be on guard lest someone catch me red-handed on some subject, maybe it’s valued to always have the last word, maybe people sees and appreciate caring for those around them. Any of these norms of behavior can give the culture of an organization.
Cultures are built and strengthened over time. Even if not all people use complex definitions or are passionate about the topic, how they talk about their organization shows the organizational culture. How they describe their interaction with their organization or how they describe their work shows what kind of culture has led to these conclusions.
A constructive organization will be described as professional, working here comes with challenges that people appreciate.
The passive organization will be perceived as bureaucratic and the work is coercive.
The aggressive organization appears hostile in interactions with the outside and the work is very demanding.
