Illinois Overtime & Labor Standards

Illinois overtime regulations combine federal FLSA standards with the state One Day Rest in Seven Act (ODRISA) administered by the Illinois Department of Labor (IDOL).

Core Illinois Overtime Formulas

• Regular Earnings: Regular Pay = Min(40, Regular Hours) × Hourly Rate

• Overtime Rate (1.5x Time-and-a-Half): Overtime Rate = Hourly Rate × 1.5

• Total Overtime Hours: Total OT Hours = Overtime Hours + 7th Consecutive Day Hours

• Total Overtime Pay: Overtime Pay = Total OT Hours × Overtime Rate

• Total Gross Pay: Gross Pay = Regular Pay + Overtime Pay

Key Provisions of ODRISA

• Mandatory 24 Hours Rest: Non-exempt employees must receive at least 24 consecutive hours of rest every calendar week.

• 20-Minute Meal Breaks: Employees working 7.5 continuous hours must receive an unpaid 20-minute meal break starting no later than 5 hours into the shift.
