Q: I know someone who cheats on expense reports at the office. What do I do?

A: Tell her that you know what she's doing. Today we live in a "no snitch" world, where there's a strange honor bestowed in not disclosing wrongdoing, but employee theft has toppled many organizations. —Rudy Rasmus, pastor of St. John's United Methodist Church in Houston

Discuss it confidentially with human resources and ask for advice. We worry about being tattletales, but in today's post-Enron world, it can be more risky to just turn your head away. —Michele Warholic Wetherald, executive director of the American Association of University Women
