Understanding Illinois Overtime Law

40-Hour Weekly Overtime Standard

Illinois enforces the federal 40-hour weekly overtime threshold through the Illinois Minimum Wage Law (820 ILCS 105). Non-exempt employees must receive 1.5× their regular rate for every hour worked beyond 40 in a workweek. Illinois law provides stronger enforcement mechanisms than federal law alone.

One Day Rest in Seven Act

Illinois has the One Day Rest in Seven Act (ODRISA), which requires employers to provide at least 24 consecutive hours of rest in every calendar week. While this does not directly change overtime calculations, it provides additional protections against excessive work schedules that often lead to overtime.

State Enforcement and Penalties

The Illinois Department of Labor actively enforces overtime laws. Employers who fail to pay overtime may face penalties including back pay, damages, and fines. Illinois law also allows employees to pursue private legal action to recover unpaid overtime — potentially with attorney's fees.

No. Illinois does not have a daily overtime threshold. Overtime is based on weekly hours only. There is also no double time requirement in Illinois.
