Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process.
Recent laws may not yet be included in the ILCS database, but they are found on this site as Public
soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the
Because the statute database is maintained primarily for legislative drafting purposes,
statutory changes are sometimes included in the statute database before they take effect.
If the source note at the end of a Section of the statutes includes a Public Act that has
not yet taken effect, the version of the law that is currently in effect may have already
been removed from the database and you should refer to that Public Act to see the changes
made to the current law.
(820 ILCS 112/10)
(a) No employer may discriminate between employees on the basis of sex by
to an employee at a rate less than the rate at which the employer pays wages to
another employee of
the opposite sex for the same or substantially similar work on jobs the
performance of which
requires equal skill, effort, and responsibility, and which are performed under
conditions, except where the payment is made under:
(1) a seniority system;
(2) a merit system;
(3) a system that measures earnings by quantity or
quality of production; or
(4) a differential based on any other factor other
than: (i) sex or (ii) a factor that would constitute unlawful discrimination under the Illinois Human Rights Act.
An employer who is paying wages in violation of this Act may not,
to comply with
this Act, reduce the wages of any other employee.
Nothing in this Act may be construed to require an employer to pay, to
any employee at a workplace in a particular county, wages that are equal
to the wages paid by that employer at a workplace in another county to
employees in jobs the performance of which requires equal skill, effort, and
responsibility, and which are performed under similar working conditions.
(b) It is unlawful for any employer to interfere with, restrain, or
deny the exercise of or
the attempt to exercise any right provided under this Act. It is
unlawful for any employer
to discharge or in any other manner discriminate against any individual for
disclosing, comparing, or otherwise discussing the employee's wages or the
of any other
employee, or aiding or encouraging any person to exercise his or her rights
(c) It is unlawful for any person to discharge or in any other manner
discriminate against any individual because the individual:
(1) has filed any charge or has instituted or caused
to be instituted any proceeding under or related to this Act;

in connection with any inquiry or proceeding relating to any right provided under this Act; or
