- What is the business justification? If a job requires an employee to handle large amounts of cash, or have access to the same, that's good justification.
- If someone has a bad credit report - especially in these economic times - does that make them a poor candidate for a job? Not necessarily.
- There is a risk that women and minorities may be disproportionately affected, and that could cause big problems.
So unless you have a good reason to do it, don't!
