There is no legal limit on how many hours you can work in a day in Illinois. Neither state law nor federal law sets a daily maximum for adult workers, so an employer can schedule a 10-, 14-, or even 20-hour shift without violating any hour cap. What the law does regulate is your right to a weekly day off, meal breaks during long shifts, and overtime pay once you cross 40 hours in a workweek. Different rules apply to workers under 16, and hospital nurses have their own protection against forced overtime.
No Daily Limit for Adult Workers
The Fair Labor Standards Act imposes no limit on daily or weekly hours for employees over the age of 15.1U.S. Department of Labor Wage and Hour Division. Fact Sheet 54 – The Health Care Industry and Calculating Overtime Pay Illinois follows the same approach. Your employer can require a shift of any length, and refusing a long shift can be grounds for discipline unless another law protects you.
Illinois also has no daily overtime rule. Working a 14-hour day does not trigger time-and-a-half if your weekly total stays at or below 40 hours. This is a common misunderstanding, especially among workers who assume Illinois works like California, which does pay daily overtime.
What the law does is limit the surrounding conditions: consecutive workdays, meal periods, and how much you get paid once the hours pile up.
The Weekly Day Off You’re Owed
The One Day Rest in Seven Act (ODRISA) is the closest Illinois comes to a scheduling ceiling. It requires most employers to give employees at least 24 consecutive hours of rest in every seven-day period.2Illinois Department of Labor. One Day Rest In Seven Act (ODRISA) In practical terms, you can be scheduled for six days in a row. On the seventh, you are entitled to a full day off.
An employer who needs coverage on all seven days can apply for a permit from the Illinois Department of Labor that allows employees to work on their rest day voluntarily. The employer must certify that no one will be disciplined for declining, and overtime rates still apply once weekly hours cross 40.3Illinois Department of Labor. ODRISA Permit Application
Who Isn’t Covered by ODRISA
Several groups fall outside ODRISA’s day-off and meal break requirements:4Illinois Department of Labor. One Day Rest in Seven Act Eff Jan 1 2023
- Watchmen and security guards
- Part-time employees working fewer than 20 hours per week
- Agricultural and coal mining employees
- Government employees
- Employees of certain seasonal producers
- Executive, administrative, professional, and outside sales employees as defined by the FLSA
- Employees covered by a collective bargaining agreement that addresses work hours, days off, and rest periods
Meal Breaks on Long Shifts
ODRISA guarantees a meal period once your shift gets long. If you work 7.5 continuous hours or more, you are entitled to at least a 20-minute meal break, and it must come no later than five hours after you start. For every additional 4.5 continuous hours after that first 7.5, you are owed another 20-minute break.2Illinois Department of Labor. One Day Rest In Seven Act (ODRISA) Your employer cannot force you to work through a meal break.5Illinois Department of Labor. One Day Rest in Seven Act FAQ
Violations carry real money. Employers with 25 or more employees face damages of up to $500 per employee per offense, plus a separate $500 penalty payable to the Department of Labor. Smaller employers face up to $250 in damages and $250 in penalties per employee per offense. Each missed break and each seven-day period without a day off counts as a separate offense for each affected worker.5Illinois Department of Labor. One Day Rest in Seven Act FAQ
Overtime After 40 Hours in a Week
Both the federal FLSA and the Illinois Minimum Wage Law require non-exempt employees to be paid overtime for any hours worked beyond 40 in a single workweek. The rate is 1.5 times your regular hourly rate. Illinois’s minimum wage is $15.00 per hour for workers 18 and older, which puts overtime pay at $22.50 per hour for minimum-wage workers.6Illinois Department of Labor. Minimum Wage Law
The threshold is weekly. Two 15-hour shifts in the same week do not trigger overtime on their own; it is the total that matters. Once you cross 40, every additional hour that week is paid at time-and-a-half.
Private sector employers in Illinois cannot substitute compensatory time off for overtime wages.7Illinois Department of Labor. Minimum Wage/Overtime FAQ If you worked 45 hours, your employer owes you five hours of overtime pay on the regular payday for that pay period. Being offered a day off the following week instead is not legal.
If you work different jobs at different pay rates for the same employer during one workweek, your overtime rate is based on a weighted average: total straight-time earnings divided by total hours, then 1.5 times that blended rate for every hour over 40.8eCFR. 29 CFR 778.115 – Employees Working at Two or More Rates
Stricter Limits for Workers Under 16
Minors are the one group with a real daily cap. Under the Illinois Child Labor Law, a minor under 16 cannot work more than three hours on a school day, and the combined time spent in school and at work cannot exceed eight hours. Weekly hours are capped at 18 during the school year and 40 during breaks.9Justia Law. Illinois Code 820 ILCS 205 – Child Labor Law
Time-of-day restrictions also apply. From Labor Day through June 1, workers under 16 cannot work before 7 a.m. or after 7 p.m. From June 1 through Labor Day, the evening cutoff extends to 9 p.m. Minors who work more than five consecutive hours must receive a 30-minute meal break, longer than the 20 minutes ODRISA gives adults. Employers must obtain an employment certificate from the minor’s school before hiring anyone under 16.
Nurses and Mandatory Overtime
Illinois hospitals cannot force nurses to work mandatory overtime except during genuine emergencies. This protection covers licensed practical nurses, registered professional nurses, and advanced practice registered nurses who are paid hourly and have direct patient care duties.10Illinois General Assembly. 210 ILCS 85/10.9 – Nurse Mandated Overtime Prohibited
The only exception is an “unforeseen emergent circumstance,” which the statute defines as a declared disaster, an activated hospital disaster plan, or a situation where patient care requires specialized nursing skills through the completion of a procedure. Even then, forced overtime cannot exceed four hours beyond the nurse’s agreed-upon shift. Chronic understaffing does not qualify; the statute specifically says a hospital’s failure to maintain adequate nursing staff is not an unforeseen emergency.10Illinois General Assembly. 210 ILCS 85/10.9 – Nurse Mandated Overtime Prohibited
Most other Illinois workers do not have an equivalent protection. Refusing a long shift outside these narrow circumstances can be treated as insubordination.
If Your Employer Broke These Rules
You can file a wage claim with the Illinois Department of Labor for unpaid overtime, missed meal breaks, or denied rest days. The Department accepts claims online, by mail, or by fax and recommends filing online for faster processing. Contact information: 800-478-3998 or DOL.MWOT@illinois.gov.11Illinois Department of Labor. Unpaid Wages
For federal FLSA claims, the statute of limitations is two years from the date of the violation, or three years if the employer’s violation was willful.12Office of the Law Revision Counsel. 29 U.S. Code 255 – Statute of Limitations Once that window closes, you lose the ability to recover.
Federal law also prohibits your employer from retaliating against you for raising wage and hour concerns. The FLSA makes it illegal to fire, demote, cut hours, or otherwise punish an employee for filing a complaint, cooperating with an investigation, or raising the issue internally. The protection applies whether you complained in writing or verbally, and it extends to former employees, so a past employer cannot blackball you for having filed a claim.13U.S. Department of Labor.
