Because there are so many different types/levels of background searches an employer can use, it is difficult to answer your question without more details. With an active PPO against you, you are on the LIEN (the "Law Enforcement Information Network"), which means if your potential employer is a police department or the FBI or CIA, they will know abut it. However, I can not confirm if a general company like Target or Walmart would find it. I would strongly recommend you truthfully fill-out all job applications (most do not ask if you have a PPO against you). I wish you all the best of luck. Warmest regards, Matt Catchick.
