Designers’ Bill of Rights

Do we need a Designers’ Bill of Rights? I’ve heard so many horror stories about how clients feel they own the designer once they are hired - they are indentured servants that can’t leave town without the approval of the client. Michele Nussbaumer, the brilliant merchandising talent behind Ceylon et Cie, laments that some of her clients hire her, and then don’t want her to say she did the job. They want to take credit. “Oh this? I just threw it together last week.” Come on, it looks easy, but like any gift, it takes talent. Any thoughts?
