Similarly, some work cultures have a spirit that emphasizes cooperation, interpersonal sensitivity, assuming the best of people, and a have a certain level of altruism in the organization's goals (even if the business is definitely private sector and for-profit). These cultures tend to be run by consensus (when possible) and to minimize conflict and internal competition. Other cultures establish norms valuing a competitive spirit (internally as well as against industry competitors) and encouraging healthy conflict. They encourage skeptical and critical examination of ideas as a normal part of the assessment of a business situation. People who thrive in this culture tend to be comfortable with conflict and are comfortable challenging co-workers when they think it will shed light on a business process ~ or will increase their advantage in a negotiation or debate.
