20 ILCS 2605/2605-610
The Illinois State Police shall not make possession of a Firearm Owner's Identification Card a condition of continued employment if the State Police officer's Firearm Owner's Identification Card is revoked or seized because the State Police officer has been a patient of a mental health facility and the State Police officer has not been determined to pose a clear and present danger to himself, herself, or others as determined by a physician, clinical psychologist, or qualified examiner. Nothing in this Section shall otherwise impair an employer's ability to determine a State Police officer's fitness for duty. A collective bargaining agreement already in effect on this issue on the effective date of this amendatory Act of the 101st General Assembly cannot be modified, but on or after the effective date of this amendatory Act of the 101st General Assembly, the employer cannot require a Firearm Owner's Identification Card as a condition of continued employment in a collective bargaining agreement. The employer shall document if and why a State Police officer has been determined to pose a clear and present danger.
