Illinois overtime laws, explained for people who run payroll.
When overtime starts in Illinois, what rate applies, what the state requires for meal and rest breaks, how often you have to pay, and what paid leave is mandated — in plain English, with a worked example. Rules change and exemptions apply, so confirm with the Illinois Department of Labor before relying on any of it.

The Illinois rules in one place.
Overtime
- Weekly: Over 40 hours in a workweek
- Daily: None — Illinois follows the weekly rule
- Seventh day: Employees are entitled to 24 consecutive hours of rest in every calendar week (One Day Rest in Seven Act)
- Rate: 1.5× the regular rate of pay, which includes non-discretionary bonuses and shift differentials
Breaks and rest
- Meal: 20-minute unpaid meal break for shifts of 7.5 hours or more, starting no later than 5 hours in; an additional 20 minutes for every additional 4.5 hours worked
- Rest: Not separately required by state law (meal break rule covers it)
- Short breaks (under 20 minutes), when offered, are paid time under federal rules
Pay and leave
- Pay frequency: At least semi-monthly; executive/administrative/professional employees may be paid monthly
- Paid leave: Paid Leave for All Workers Act: up to 40 hours of paid leave a year, usable for any reason (Chicago and Cook County have their own ordinances)
- Recordkeeping: hours worked each day and week must be recorded and kept (federal rule: 3 years for payroll records)
Illinois vs. federal law.
Federal law sets the floor. States can add to it, and several do.
| Rule | Illinois | Federal FLSA |
|---|---|---|
| Overtime after 40 hours in a workweek | Yes | Yes |
| Daily overtime | No | No |
| Seventh-day or rest-day rule | Yes | No |
| Meal break required for adults | Yes | No |
| Rest breaks required for adults | No | No |
| Paid sick leave or paid leave mandated | Yes | No |
| Pay-frequency rule | Yes | No |
| Overtime rate | 1.5× regular rate | 1.5× regular rate |
| Records of hours worked required | Yes | Yes |
Where Illinois and federal law differ, the rule more favorable to the employee applies. Exemptions (executive, administrative, professional, outside sales and others) are not covered here.
How the Illinois rules work in practice.
What a real week looks like.
A crew works 7.5-hour shifts, Monday through Saturday — 45 hours. Five hours of overtime at 1.5×, each shift needs its 20-minute meal break, and the week must still include one 24-hour rest period.
- The 24-hour rest rule is unusual and applies on top of overtime
- Meal break timing (by the 5th hour) is enforced
- Paid Leave for All Workers accrual is 1 hour per 40 worked unless front-loaded
Overtime is 1.5× the regular rate, not 1.5× the hourly wage.
If an employee earns a non-discretionary bonus, a shift differential or multiple hourly rates in the same week, those are folded into the regular rate before the 1.5× multiplier. Getting this wrong is the most common overtime error in wage claims.
- Non-discretionary bonuses count
- Shift differentials count
- Discretionary bonuses, expense reimbursements and PTO payouts don't
