820 ILCS 40/6
If the employee disagrees with any information contained in the personnel record, a removal or correction of that information may be mutually agreed upon by the employer and the employee. If an agreement cannot be reached, the employee may submit a written statement explaining the employee's position. The employer shall attach the employee's statement to the disputed portion of the personnel record. The employee's statement shall be included whenever that disputed portion of the personnel record is released to a third party as long as the disputed record is a part of the file. The inclusion of any written statement attached in the record without further comment or action by the employer, shall not imply or create any presumption of employer agreement with its contents. If either the employer or the employee knowingly places in the personnel record information which is false, the employer or employee, whichever is appropriate, shall have remedy through legal action to have that information expunged.
