IL HB2794

Amends the Employee Classification Act to make developers, general contractors, and subcontractors jointly and severally liable for any subcontractor's failure to properly classify workers as employees in construction projects

Developers and general contractors can avoid liability only by demonstrating they were unaware of the misclassification, could not have discovered it through reasonable diligence, and took all reasonable steps to prevent misclassification

Expands the definition of "interested party" to explicitly include labor unions, worker centers, and employee associations that represent workers in the industry where misclassification occurred

Adds a new definition of "developer" as any person contracting with a contractor for construction or renovation of a structure for commercial purposes

Extends penalties, debarment provisions, retaliation protections, and private right of action provisions to apply to developers and general contractors, with willful violators subject to Class C misdemeanor (first offense) or Class 4 felony (repeat offense within 5 years)
