Quick Answer

Understand Illinois overtime requirements. Learn who qualifies, how overtime is calculated, exemptions, and how to recover unpaid overtime.

Quick Answer: Illinois requires overtime pay at 1.5 times your regular rate for hours worked over 40 per week. Both state law (One Day Rest in Seven Act) and federal FLSA apply. Most hourly employees qualify, but certain executive, administrative, and professional employees are exempt. If you're owed overtime, file a complaint with the Illinois Department of Labor or pursue legal action.

Working extra hours should mean extra pay.

Illinois Overtime Requirements

The Basic Rule

Overtime rate: 1.5 × regular hourly rate Trigger: Hours worked over 40 in a workweek Applies to: Most non-exempt employees

Illinois Law

One Day Rest in Seven Act:

  • Requires overtime after 40 hours/week
  • Works alongside federal FLSA
  • Provides additional protections

How Overtime Is Calculated

Example:

  • Regular rate: $20/hour
  • Hours worked: 50
  • Regular pay: 40 × $20 = $800
  • Overtime pay: 10 × $30 = $300
  • Total: $1,100

Who's Entitled to Overtime

Common Overtime Violations

Misclassification

Problem: Employer incorrectly classifies you as exempt

Signs:

  • Salary doesn't meet threshold
  • Duties don't match exemption
  • Title doesn't reflect actual work

Off-the-Clock Work

Problem: Work performed but not recorded

Examples:

  • Post-shift cleanup
  • Work during "unpaid" breaks
  • Answering emails at home

Averaging Hours

Problem: Employer averages hours across pay periods

Illegal: Cannot average 30-hour week with 50-hour week to avoid overtime. Each week stands alone.

Comp Time Instead of Pay

Problem: Private employer offers comp time instead of overtime pay

Note: Private employers generally must pay overtime—cannot substitute comp time.

Common Scenarios

Scenario 1: Salaried But Non-Exempt

Situation: You're paid salary of $600/week, work 50 hours, duties are clerical.

Analysis: Below salary threshold and duties don't qualify as exempt. Entitled to overtime.

Scenario 2: Working Through Lunch

Situation: You clock out for lunch but work through it most days.

Analysis: Work time must be paid. If it pushes you over 40 hours, overtime is owed.

Scenario 3: Multiple Jobs, One Employer

Situation: You work two positions for same employer, totaling 50 hours.

Analysis: Hours for same employer combine. Overtime owed after 40 total hours.

Scenario 4: "Manager" Title, No Authority

Situation: You're called "assistant manager" but have no hiring/firing authority and primarily do non-managerial work.

Analysis: Title doesn't determine exemption—duties do. May be entitled to overtime.

Frequently Asked Questions

Do all workers get overtime?

No. Exempt employees (executive, administrative, professional, etc.) don't qualify. But many workers incorrectly classified as exempt are actually entitled to overtime.

Can my employer make me work overtime?

Generally yes. Refusing may be grounds for discipline. But they must pay you for the extra hours.

Can I waive my right to overtime?

No. You cannot waive overtime rights. Any agreement to work overtime without proper pay is unenforceable.

What if I'm paid salary?

Salary alone doesn't mean you're exempt. Must meet both salary threshold AND duties test. Many salaried workers are entitled to overtime.

How far back can I recover?

2-3 years under federal law. Up to 3+ years under Illinois law depending on claim type.

Do I need a lawyer?

Not required for IDOL complaint. But for complex cases or large amounts, an attorney can help maximize recovery.
