Charles JacksonDoes Illinois require employers to provide paid sick leave? Yes — and since January 1, 2024, it requires something broader: paid leave that can be used for any reason at all, with no documentation requirement and no explanation owed to the employer. The Illinois Paid Leave for All Workers Act (PLAWA, 820 ILCS 192/) covers nearly every private-sector worker in the state and represents one of the most expansive paid leave mandates in the United States. Here are the questions Illinois workers and HR teams ask most.
How Much Paid Leave Does Illinois Law Require?
PLAWA requires employers to provide at least 40 hours (5 working days) of paid leave per year to covered employees. Leave accrues at a rate of 1 hour for every 40 hours worked. A full-time employee working 40 hours per week earns the full 40-hour entitlement after approximately 10 months of employment.
Accrued leave carries over from one year to the next — but the employer may cap the total amount of leave used in any one year at 40 hours. An employee who carries over 40 hours of unused leave into the new year does not gain additional leave on top of the carryover; the cap limits use, not accrual.
| Key PLAWA Number | Value |
|---|---|
| Annual leave entitlement | 40 hours (5 days) |
| Accrual rate | 1 hour per 40 hours worked |
| Waiting period before first use | 90 days from date of hire |
| Carryover allowed | Yes |
| Annual usage cap | 40 hours |
| Reason required to use leave | None |
| Documentation employer may demand | None |
| Chicago additional entitlement | Up to 5 days sick leave (separate ordinance) |
Who Is Covered Under PLAWA?
PLAWA covers virtually all private-sector employees in Illinois, including part-time workers, temporary employees, and seasonal workers. Coverage begins on day one of employment; accrual begins immediately. The 90-day waiting period applies only to the first use — employees accrue leave from day one but may not use it until 90 days after hire.
Who is NOT covered:
- Employees covered by a collective bargaining agreement (CBA) in effect before January 1, 2024, where the CBA explicitly addresses leave — until that CBA expires
- Employees of the federal government
- Certain agricultural workers covered under separate federal provisions
- Domestic workers employed by households with fewer than 1 employee for 16 or more weeks per year (covered under a separate Illinois domestic workers statute)
Part-time workers: PLAWA explicitly covers part-time employees. A worker who works 20 hours per week accrues 1 hour of leave for every 40 hours worked and must be allowed to use it under the same rules as a full-time employee.
Can an Employer Require a Doctor's Note to Use PLAWA Leave?
No. PLAWA prohibits employers from requiring employees to provide documentation, explanation, or advance notice for leave taken under the Act. The right to take leave for any reason is the core feature — an employer may not ask why the employee is taking leave, require a doctor's note, or deny leave because the stated reason seems inadequate.
An employer may require reasonable advance notice when the need for leave is foreseeable — for example, a pre-scheduled medical appointment. For unforeseeable leave (sudden illness, family emergency), the employer may require the employee to notify a supervisor "as soon as practicable."
"PLAWA is fundamentally different from traditional sick leave laws. The employer has no right to evaluate the legitimacy of the reason. If the employee has accrued hours and isn't already on leave for a separate reason, they're entitled to use it." — HR compliance perspective, Chicago Society for Human Resource Management (SHRM), 2024
What If My Employer Already Offers PTO?
An employer whose existing PTO or paid leave policy provides at least 40 hours per year and permits unrestricted use (for any reason, with no documentation requirement) is in compliance with PLAWA — a separate bucket of PLAWA leave is not required.
However, if the existing PTO policy restricts use (for example, requiring that leave be used only for illness or approved personal days), it does not comply with PLAWA's "any reason" mandate. The employer must either modify the existing policy or provide a separate PLAWA-compliant leave bank.
Real scenario: Daniela works at a distribution center in Romeoville that offers 5 days of sick leave and 5 days of personal leave per year. Her employer argues the 10-day total exceeds PLAWA's 40-hour minimum. But the sick leave policy requires a doctor's note after two consecutive sick days. Does the policy comply? No — the documentation requirement for sick leave violates PLAWA's no-documentation rule. The employer must remove the doctor's note requirement or provide a separate PLAWA leave pool.
Are Chicago Workers Covered by Different Rules?
Yes — Chicago has its own ordinance that is more generous than PLAWA. The Chicago Paid Leave and Paid Sick and Safe Leave Ordinance (effective July 1, 2024 in its current form) provides:
- 5 days of paid leave usable for any reason (similar to PLAWA but separately tracked)
- 5 days of paid sick and safe leave usable for illness, domestic violence, or care of a family member
Chicago workers are entitled to both categories — up to 80 hours total — and employers must comply with whichever rule is most favorable to the employee. Cook County has a similar ordinance for workers outside Chicago city limits.
For the broader context of how PLAWA fits into Illinois's employment law landscape, the Illinois Labor Law dossier covers overtime, minimum wage, and other key protections in one place.
What Happens If an Employer Violates PLAWA?
An employer who denies PLAWA leave, retaliates against an employee for using it, or fails to maintain proper records faces:
- Civil penalties up to $2,500 per violation assessed by IDOL
- Reinstatement and back pay for retaliatory terminations
- A three-year statute of limitations on enforcement claims
Workers may file complaints with the Illinois Department of Labor at no cost.
