Instead of reacting to circumstances or people, the professional stops to think about her actions before she responds. She takes action when needed, but avoids being a reactionary person. She treats everyone with the same level of respect, regardless of the positions they hold within the company. than the norm.
Ethics: Ethics represent the core values you hold or that a company sets in its “Code of Ethics.” While ethics might have different meanings at different companies, generally ethics refers to how you behave. A company’s code of ethics often requires that you agree to honesty and transparency in your actions, and that you show your co-workers respect regardless of their culture, the color of their skin or their personal beliefs. Ethical people respect the rights and privacy of others as well as the confidential requirements often held by the company for which they work.
