3 Big Things: What to Know About Illinois’ New Prevailing Wage Language
SMACNA Greater Chicago welcomed Christina Wernick of Laner Muchin as the featured speaker at our May Membership Meeting. Wernick, a labor and employment attorney who now represents management, pulled no punches from the start: “This is not going to be a feel-good presentation, but it’s critical to your industry.”
The subject was HB 2488 (now an Act) and the sweeping changes it makes to the Illinois Prevailing Wage Act, which took effect July 1, 2026. Here are the three things every contractor needs to understand.
What Changed and Why It Matters
HB 2488 flew under the radar when it was introduced, and that’s part of the problem. The amendment to the Illinois Prevailing Wage Act requires that apprentices on prevailing wage projects receive the full journeyman-level fringe benefits — regardless of what your collective bargaining agreement says. IMSCA helped push the original effective date back to July 1 to give contractors more runway, but that date has now come and gone — the requirement is live. IDOL has been unambiguous: its enforcement position is that apprentices on prevailing wage projects must receive the full journeyperson benefit rate. Importantly, labor is divided on this issue. AFL-CIO has not taken a stance, and IDOL isn’t rushing to issue guidance, making it harder for contractors to get clear answers.
Compliance and Enforcement
Wernick outlined two primary paths to compliance, noting non-compliance carries steep penalties: 20% annual interest on backpay or 5% compounding monthly. SMART Locals 73 and 265, together with SMACNA Greater Chicago, have reached agreements requiring that full journeyman fringe benefit contributions be paid for all apprentice hours worked on prevailing wage projects. As of this writing, the Local 73 and Local 265 Fund Offices are updating their online payment portals to accommodate these contributions. Additional information regarding the reporting procedures will be provided as soon as it becomes available.
Key Takeaways
Wernick’s action items, to be completed without delay since the requirement is already in force:
• Review your CBAs with legal counsel to understand where HB 2488 supersedes negotiated apprentice fringe benefit provisions.
• Update your bid models to reflect higher apprentice costs on prevailing wage work — government projects are the clearest indicator; renewable energy credit projects may also qualify.
• Don’t wait to update payroll systems, benefit fund reporting and project accounting. The compliance window is already open.
• Consult legal counsel. Guidance from IDOL is limited, and the stakes are high.
