Understanding Illinois Overtime
What is Overtime?
Overtime is compensation paid for hours worked beyond the standard 40-hour workweek. In Illinois, overtime must be paid at 1.5 times (time and a half) your regular hourly rate for all hours over 40 in a workweek.
Time and a Half
"Time and a half" means your overtime rate is 150% of your regular pay. For example, if you earn $20/hour regularly, your overtime rate is $30/hour ($20 × 1.5 = $30).
Illinois vs Federal Law
Illinois overtime law aligns with the Federal Labor Standards Act (FLSA). When both laws apply, employees are entitled to the more favorable provision. Illinois law explicitly prohibits compensatory time off in the private sector.
Workweek Definition
A workweek is any fixed, recurring period of 168 hours (7 consecutive 24-hour periods). It doesn't have to align with the calendar week and can begin on any day and time established by the employer.
Common Questions
Q: Can my employer give me comp time instead of overtime pay?
A: No. In Illinois, private sector employers cannot offer compensatory time off instead of overtime pay. This is illegal under state law.
Q: Do I get overtime if I work weekends?
A: Only if you work more than 40 hours in the workweek. Weekend work itself doesn't automatically qualify for overtime unless it pushes you over 40 hours total for the week.
Q: Am I eligible for overtime if I'm salaried?
A: It depends. Not all salaried employees are exempt from overtime. You must meet specific job duties and salary threshold requirements to be considered exempt under Illinois law.
