Why is it important to perform background screening of employees?

Employers today have the right to learn more about the candidates they are about to commit to a legal relationship with. They also have the right to ensure that a potential new hire does not have anything lurking in their past that could potentially harm the business or create a safety hazard for clients and other employees.
It's important that the candidate is thoroughly screened to ensure that all the experience and credentials listed are accurate for the needs of each job order.
