CLS Background Investigations

05/19/2026

Hiring a firefighter with undisclosed history isn't just a personnel problem.
It's a liability exposure for your city or municipality.

When something goes wrong — and it does — the first question attorneys ask is:
"What did you know, and when did you know it?"

Negligent hiring claims in public safety are real, they're expensive, and they're almost always preventable.

A thorough pre-employment background investigation isn't just best practice.
It's your department's first line of defense.

We provide comprehensive, legally defensible background investigations built specifically for fire departments — compliant with FCRA, ADA, and Title VII.

Most fire departments run a background check. Very few run a background investigation.

There's a real difference — and it matters more than most chiefs realize.

A background check tells you if someone has a criminal record.
A background investigation tells you who someone actually is.

We look at employment history, personal references, social media, and a full applicant interview, driving records and professional certifications — not just a database query.

If you're putting someone in a home with vulnerable people at 3am, that difference matters.

Here is what one of our client's has to say:

We are so very thankful for CLS Enterprises! We have never received the degree of proper background screening with any service that we had used in the past. Also, their team – absolutely amazing and such a pleasure to work with. I truly believe that we would have wasted a lot of time and money if we had never found them….not to mention REALLY bad hires. THANK YOU CLS TEAM!

If anyone knows this young lady. I would love to be put in touch with her for a brief interview.

Video shows a University of Chicago student being confronted as she was walking down a sidewalk, and she spoke with ABC7 about the ordeal. The school issued a safety alert Wednesday after multiple students were robbed.
