Most employers don’t consider background checking their new hires as being a way to protect their current employees, but that’s a huge outcome of making certain all workers brought into an office have been properly vetted. (It’s also a selling point for potential new hires because they know that they’ll be secure at the organization.)
Let’s consider bit of investigating, he would have discovered the problem immediately.
Using this anecdote as a platform to make the point, the employer is really like the shepherd, and it’s up to him or her to maintain a safe environment for all employees. With background checks, companies are taking all the steps necessary to lessen the chances that someone with nefarious tendencies or desires will find themselves on their payrolls.
What kind of shepherd are you going to be? One who takes the job seriously or one who looks the other way when solvable problems arise?
