You are a manager of a retail store. You are given permission by the owner of the store to hire a fellow classmate to help out. One day you see the classmate take some clothing from the store. When confronted by you, the peer laughs it off and says the owner is insured, no one is hurt, and it was under $100. "Besides," says your acquaintance, "friends stick together, right?" What would you do?
Address each of these ethical systems in relation to the scenario.
I have taken the liberty of discussing the various points raised in your post regarding the scenario. I did not answer 'in-character' being that I preferred to look into it from an 'advisory' point of view so as to give particular ethical systems room for discussion.
