Ava is working with Monica and Fred on a proposal to redesign some window displays at the department store where they all work. Monica says, “Fred’s off work today, so let’s show the boss the ideas we came up with and say they’re just from you and me. There’s only one promotion available this season, and I want to make sure you or I get it. Fred’s ideas weren’t that great anyway.” Would it be ethical to present the ideas without crediting Fred? What should Ava do in this situation?
