Court Declares “Interested Party” Provisions of the Illinois Day and Temporary Labor Services Act Unconstitutional

Why It Matters

The ruling curtails union‑driven enforcement of temporary‑worker protections, potentially reducing penalty exposure for staffing firms and altering the litigation landscape in Illinois labor law.

Key Takeaways

• Section 67 deemed unconstitutional, removing private “interested party” lawsuits.
• Court ruled the statute usurps Illinois Attorney General’s enforcement authority.
• Union‑sponsored groups lose direct penalty‑seeking power under the Act.
• Remaining provisions of the Act stay effective for worker protections.
• Employers must reassess compliance strategies and monitor potential appeals.

Pulse Analysis

The Illinois Day and Temporary Labor Services Act was originally designed to extend wage, benefit, and safety standards to day and temporary workers, a segment historically vulnerable to exploitation. In 2023, lawmakers expanded the Act with Section 67, granting "interested parties"—typically unions or worker‑rights groups—the ability to sue agencies and client companies for alleged non‑compliance, and to collect a share of statutory penalties. This private enforcement mechanism was hailed as a powerful tool to hold staffing firms accountable without overburdening state resources.

In the March 6, 2026 case *Figueroa v. Visual Pak Holdings, LLC*, the Cook County Circuit Court concluded that Section 67 violates the Illinois Constitution by effectively creating a qui tam statute that bypasses the Attorney General. The court emphasized that the state, not private entities, holds the substantive interest in enforcing labor statutes, and that the lack of any notice or control provision for the Attorney General undermines executive authority. By striking down the private‑suit provision, the decision restores exclusive state control over enforcement while preserving the Act’s core worker‑protection provisions.

For businesses, the ruling signals a shift from private litigation risk to reliance on state‑initiated actions. Staffing agencies and their client employers must now focus on internal compliance programs and cooperate with the Illinois Department of Labor, rather than fearing class‑action suits by unions. Legal counsel should reassess risk assessments, monitor any appellate activity, and advise on documentation practices to demonstrate good faith compliance. The broader trend reflects heightened judicial scrutiny of private enforcement tools, suggesting that other states may reevaluate similar statutes to balance worker protection with constitutional limits.
