IDOL's Cook County schedule, posted October 19, 2026, for work performed on or after October 19, 2026. Checked against labor.illinois.gov on October 24, 2026.

Base wage and fringe: $54.98 + $41.85

The base wage is the taxable hourly wage. The other lines are the fringe benefits IDOL lists for each hour: health and welfare, pension, vacation, training, and "other insurance", which IDOL's legend defines as the "employer hourly cost for any other type(s) of insurance".

Base wage (taxable)	$54.98
Health and welfare	$18.50
Pension	$22.10
Training	$1.25
Base + fringes (our sum; IDOL prints no total)	$96.83

IDOL leaves the other insurance column blank for this row, not $0.00. Our sum counts blank as zero.

Foreman base wage: $58.28 an hour, with the same fringe benefits.

Overtime

When	Multiple of base
Monday to Friday, after 8 hours a day	1.5× $82.47
Saturday, every hour	1.5× $82.47
Sunday, every hour	2.0× $109.96
Holidays, every hour	2.0× $109.96

IDOL prints a multiple, not a dollar rate. Its legend: “Unless otherwise noted, OT pay is required for any hour greater than 8 worked each day, Mon through Fri. The number listed is the multiple of the base wage.” The figure under each multiple is the base wage times that multiple.

IDOL's schedule also has two columns headed “Add OT 1.5x owed” and “Add OT 2.0x owed”. For this row they read $0.00 and $0.00. IDOL's legend doesn't define them, so ask IDOL (217-782-1710) before you rely on them.

Davis-Bacon plasterer rate in Cook County

Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. When a contract requires both the state rate and the Davis-Bacon rate, paying the higher of the two meets both. The contract documents say which apply.

For building work, the matching Davis-Bacon classification is PLASTERER at $68.90 ($42.25 base + $26.65 fringe), from IL20260009 modification 3, published October 22, 2026, rate PLAS0005-002. Against IDOL's $96.83: IDOL's rate is $27.93 an hour higher.

Holidays

IDOL's Cook 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. Common practice in a given local may alter certain days of celebration. If in doubt, please check with IDOL.”

Holiday work is paid at the holiday multiple in the overtime table (2.0× the base wage for this row).

When this rate changes

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).
