Not necessarily, but that also depends on the case. It depends on a lot of factors, including the nature of the offense, whether there is a lot of media publicity, and whether or not your employer has reporting requirements. Many government jobs or federal contracting jobs have requirements about reporting arrests or convictions. Your employer might find out about a criminal offense if they do active criminal background checks. Many background checks only check for convictions, but if the person doing the background check is looking for an arrest record either by going to the NCIC database (National Crime Information Center) or by searching through the local court records, an arrest may show up as well.
