Employers too need to be sure that they're hiring right individuals for their organization. A bad background check could be the difference between an honest employee and one with a criminal record. It could also mean that the employer hires a person who isn't trustworthy or is likely to cause trouble within the workplace. Background checks are performed by employers for a variety of reasons. The most common is finding out information about an applicant's employment history, work knowledge or experience, previous employment, as well as character references from employers.
