When does this rate change?
- Illinois rates don't lock at bid. When IDOL revises a rate, “the revised rate shall apply to such contract” from its effective date, including jobs already under way (820 ILCS 130/4(l)).
- A missing notice is no excuse. A public body's failure to send the new rates “does not relieve the contractor of the duty to comply”, or of paying back wages (820 ILCS 130/4(g), (j)).
- IDOL surveys in June and must publish the year's schedule by July 15 (820 ILCS 130/9), then posts revisions through the year. In 2026 its postings took effect on Jan 15, Mar 2, Apr 15, May 21, Jul 15, Aug 15, Sep 21 and Oct 19, 2026. Each posting replaces all 102 county schedules.
- This page uses the posting for work performed on or after October 19, 2026 (IDOL current rates; older postings are on IDOL's historical rates page).

Holidays
IDOL's Grundy County schedule: “The following list is considered as those days for which holiday rates of wages for work performed apply: New Years Day, Memorial Day, Fourth of July, Labor Day, Thanksgiving Day, Christmas Day and Veterans Day in some classifications/counties. Generally, any of these holidays which fall on a Sunday is celebrated on the following Monday. This then makes work performed on that Monday payable at the appropriate overtime rate for holiday pay.
