This article is intended for business law and legal environment instructors who want to help students understand how they might react when presented with an ethical conflict, no matter how big or how small. The article discusses not only the compelling ethical issues that may arise in reneging cases, but also legal issues. The article provides materials on reneging that instructors may use to help students understand the roles of law and ethics, and also to teach students to spot and give critical thought to ethical issues they may encounter in the early part of their careers. Such personal relevance is likely to make this an engaging topic for students. The article begins by reviewing the legal and ethical issues presented in reneging cases. Next, the article suggests options for presenting reneging in a legal studies classroom, to enhance coverage of contract law and employment at will and to prompt critical thought about the ethics of reneging. Finally, the article assesses the content of over sixty student papers on reneging and reports on a statistical analysis of pre- and post-course student surveys on the ethics of reneging, which may shed further light on student attitudes toward the topic and allow some modest conclusions about the effect of a business law course on student attitudes. (Contains 2 tables and 94 footnotes.)
