Illinois Overtime Law Overview

Illinois overtime law requires employers to pay eligible employees one and a half times (1.5x) their regular hourly rate for all hours worked beyond 40 in a single workweek. This law is governed by the Illinois Minimum Wage Law (820 ILCS 105/) and closely aligns with the federal Fair Labor Standards Act (FLSA).

The Illinois Department of Labor enforces these regulations to ensure workers receive fair compensation for their extra labor. Unlike some states that require daily overtime (pay for hours over 8 per day), Illinois uses a weekly threshold only.

The current Illinois minimum wage is $14.00 per hour as of 2024, which means the minimum overtime rate is $21.00 per hour. Chicago has a higher minimum wage of $15.80, resulting in a minimum overtime rate of $23.70 per hour for Chicago workers.

How to Calculate Overtime Pay

Calculating overtime pay in Illinois involves a simple formula:

Step-by-Step Calculation

1. Determine your regular hourly rate - This is your standard pay rate before overtime.
2. Calculate overtime hours - Subtract 40 from your total weekly hours. Only hours above 40 count as overtime.
3. Calculate your overtime rate - Multiply your regular rate by 1.5.
4. Calculate regular pay - Multiply 40 hours (or fewer if you worked less) by your regular rate.
5. Calculate overtime pay - Multiply overtime hours by your overtime rate.
6. Add them together - Regular pay + Overtime pay = Total gross pay.

Who is Eligible for Overtime?

In Illinois, most hourly workers are entitled to overtime pay. You're likely eligible if you:

• Are paid on an hourly basis
• Work for a private sector employer
• Are not classified as an exempt employee
• Work more than 40 hours in a workweek

Certain government employees and employees covered by collective bargaining agreements may have different overtime rules.

Employees whose primary duty is management, who regularly direct two or more employees, and who earn at least $684 per week salary may be exempt.

Administrative Exemption

Employees performing office or non-manual work related to management policies, who exercise discretion and independent judgment, and earn at least $684 per week salary.

Professional Exemption

Comp Time vs. Overtime Pay

Compensatory time off ("comp time") is when employers offer time off instead of overtime pay. Here's what you need to know about Illinois:

Only government employers (federal, state, and local) may offer comp time to employees under certain conditions, typically at a rate of 1.5 hours of comp time for each hour of overtime worked.

Frequently Asked Questions

Is overtime pay mandatory in Illinois?

Yes, for non-exempt employees. Employers must pay 1.5 times the regular rate for all hours worked over 40 in a workweek. There is no option to opt out or receive comp time instead (in the private sector).

Do I get overtime after 8 hours a day in Illinois?

No, Illinois uses a weekly overtime threshold only. You receive overtime for hours worked over 40 per week, regardless of how many hours you work per day. Working 10-hour days for 4 days (40 hours total) would not trigger overtime.

Can my employer force me to work overtime?

Generally yes, employers can require overtime work unless prohibited by a contract or collective bargaining agreement. However, they must pay you the overtime rate for those hours.

What if my employer doesn't pay overtime?

This is a violation of Illinois and federal law. You can file a complaint with the Illinois Department of Labor or the U.S. Department of Labor. You may also have grounds for a private lawsuit to recover unpaid wages plus penalties.

Are salaried employees entitled to overtime?

It depends. Being paid a salary doesn't automatically make you exempt from overtime. You must meet specific criteria regarding job duties and earn at least $684/week ($35,568/year) to be exempt. Many salaried workers are actually entitled to overtime.

How is the workweek defined?

A workweek is any fixed, recurring period of 168 hours (seven consecutive 24-hour periods). It doesn't have to be Sunday-Saturday; employers can define it to start on any day. Once established, the workweek cannot be changed to avoid overtime obligations.
