this is to minimize the risk of internal fraud, inventory loss, potential staff issues, etc.

Its not all grim - There are some counterbalances that saavy employers can leverage. I believe some states , such as NJ, will reward employers that hire ex-felons. These amounts are quite large.

Of course, not all employers want to take the time to do an assesment of a potential hire with a criminal background.

You can have a clear background, never be charged with a crime, and still lose your job. Happens with increasing frequency.

Cheap insurance.
