A private school hires someone as a counselor or a basketball coach, and does only a moderate job of vetting them. After all, who wants to pay big money to go into some voluminous exploration into someone's history? So this new employee molests a child, or even just gets accused of doing so, and the bright lights come on. The first question will be, "did you do a thorough background on this person?"
If the answer is "no", then the pound of cure--which might instead be a stake in the heart rather than a cure at all--comes in the form of a searing lawsuit, and the settlement could put the school out of business, depending on what kind of insurance they have. If you've never seen personal injury lawyers in action, stand back. They'll go after the coach, the principal, the ones responsible for providing training, and the corporate entity itself. Besides the settlement, the lawyers' fees to defend such an onslaught are daunting enough.
The ounce of prevention? Depending on the breadth of the background investigation, maybe $95, or a little more, if there are court records to pull.
NSI recently did a background check for a client and found that an existing employee, not a prospective one, was a registered sex offender, one who preyed on children. The client's business catered to tourist families. The employee was on federal probation for the charges, and one of the conditions of the probation was that he not be employed in any capacity that put him in the presence of children.
He screwed up when he took the job, but that doesn't let his employer off the hook, because today's mindset says, "you should have known, or at least taken the effort to find out."
If you are getting deeper into a relationship with someone, you shouldn't have unanswered questions. This is the case whether the relationship is a romantic one, a business venture, or a potential hire. In any one of those three endeavors, you can get hurt. When your heart gets broken, you'll eventually get over it. If your business' name gets splashed all over the news because your unwillingness to do your due diligence caused someone harm, you might not.
