Illinois Paid Leave for All Workers Act 2024: Complete Guide

On January 1, 2024, Illinois became one of only a handful of states to require paid leave for nearly all private-sector workers — not just sick leave, but paid leave that can be used for any reason whatsoever. The Paid Leave for All Workers Act (PLAWA) is one of the most significant expansions of employee leave rights in Illinois history, and two years in, many employers and employees still don't fully understand what it requires.

This guide covers what the law requires, how it interacts with existing PTO policies, what Illinois law says about PTO payout at termination, and what employers need to do to stay compliant in 2026.

The Paid Leave for All Workers Act (PLAWA) — What It Requires

Effective January 1, 2024, most Illinois employers must provide their employees with up to 40 hours of paid leave per year. This is a landmark law for several reasons:

It covers any reason. Unlike sick leave laws in other states, PLAWA paid leave isn't restricted to illness, family care, or specific qualifying events. Employees can use it for any purpose — a dentist appointment, a child's school play, a personal errand, or simply a day off. Employers cannot require employees to disclose why they're taking leave.

It's nearly universal. PLAWA covers virtually all private-sector Illinois employees, including part-time and seasonal workers, with very limited exceptions (domestic workers covered under other laws, certain employees covered by valid collective bargaining agreements, and a few others).

The accrual rate is 1 hour for every 40 hours worked. An employee working 40 hours per week will accrue approximately 1.25 hours of PLAWA leave per week, reaching the 40-hour annual cap in about 32 weeks. Part-time employees accrue at the same rate proportionally.

When Can Employees Start Using It?

Employees begin accruing PLAWA leave from their first day of employment. However, employers can require that employees wait until they've been employed for 90 days before using accrued leave. After 90 days, employees can use leave as it accrues — they don't have to wait until they've hit a large balance.

Rollover and Year-End Rules

PLAWA leave must carry over from year to year — employers cannot implement a use-it-or-lose-it policy for PLAWA leave. Employees can carry up to 40 hours of PLAWA leave into the next benefit year.

However, employers can cap how much leave an employee uses per year at 40 hours, even if the employee has a larger banked balance due to rollover. The rollover protects employees from losing hours they've earned; the usage cap prevents the bank from growing indefinitely into a large liability.

PLAWA vs. Existing PTO Policies: How They Interact

Many Illinois employers already offer PTO that meets or exceeds PLAWA's 40-hour requirement. These employers don't need to create a separate PLAWA leave bank — they just need to ensure their existing PTO meets PLAWA's conditions.

For existing PTO to satisfy PLAWA, it must:

• Provide at least 40 hours of paid leave per year
• Allow use for any reason (not restricted to illness or specific qualifying events)
• Carry over from year to year (no use-it-or-lose-it for the first 40 hours)
• Be available under the same accrual timeline (usable after 90 days)

If an employer's existing PTO policy meets all of these requirements, the employer is compliant. If the existing policy is more restrictive in any way — say, it's sick-leave-only, or it has a use-it-or-lose-it year-end rule — the employer must modify the policy or create a separate PLAWA leave bank.

Illinois Vacation Payout: Separate and Stronger Rules

PLAWA doesn't require vacation payout at termination. But Illinois has a separate, older rule that does — and it applies to vacation (as opposed to PLAWA leave).

Under the Illinois Wage Payment and Collection Act, accrued vacation time is treated as earned wages. Illinois employers cannot implement a use-it-or-lose-it vacation policy, and they must pay out accrued, unused vacation at termination.

This creates a compliance nuance for Illinois employers with combined PTO banks: if your PTO bank covers both PLAWA leave and vacation, the vacation portion must be paid out at termination. Employers who want to avoid vacation payout liability sometimes separate their leave banks — one for PLAWA-qualifying leave (no payout required) and one for vacation (payout required).

For Employers: PLAWA Compliance Checklist

Two years in, Illinois employers should have PLAWA compliance fully dialed in. Here's a quick checklist:

• ☐ Written PTO policy updated to reflect PLAWA requirements as of January 1, 2024
• ☐ Employee handbook updated and distributed
• ☐ Payroll system configured to track PLAWA accrual separately or confirm existing PTO meets requirements
• ☐ Required PLAWA workplace notice posted (Illinois DOL poster)
• ☐ 90-day waiting period applied consistently if used
• ☐ No use-it-or-lose-it provision in place for first 40 hours of annual leave
• ☐ Rollover up to 40 hours implemented in payroll system
• ☐ Vacation payout policy clearly addressed in handbook (separate from PLAWA)

HR software with Illinois-specific configurations can automate much of this — including separate PLAWA accrual tracking, rollover enforcement, and termination payout calculations. If you're managing Illinois employees manually, the risk of non-compliance grows with every payroll cycle.

Frequently Asked Questions

Does PLAWA apply to my small Illinois employer?

Yes, with very few exceptions. PLAWA covers virtually all private employers in Illinois regardless of size — including businesses with just one employee. The main exceptions are employers covered by the federal Railway Labor Act, certain temporary staffing arrangements, and employees covered by a valid collective bargaining agreement that explicitly waives PLAWA rights.

Can my Illinois employer ask why I'm using PLAWA leave?

No. PLAWA explicitly prohibits employers from requiring employees to provide a reason for taking leave or to find a replacement worker as a condition of using leave. You don't have to explain a PLAWA day off.

Does PLAWA replace Illinois sick leave?

PLAWA is a different and broader law than sick leave. Illinois's existing Employee Sick Leave Act (820 ILCS 191) requires employers who offer sick leave to allow it to be used for family member care — that law still exists. PLAWA is a new, additional requirement: 40 hours of any-reason paid leave. The two laws coexist.

My Illinois employer offers 15 days of PTO. Do they still need to comply with PLAWA?

Probably yes — but only if their existing 15-day PTO policy meets PLAWA's conditions (any-reason use, rollover required, usable after 90 days). If the 15-day PTO is already structured this way, no additional leave is needed. If the existing policy is sick-leave-only or has a use-it-or-lose-it rule, the employer must modify the policy or add a separate PLAWA leave bank.

Does Illinois require payout of PLAWA leave at termination?

No. PLAWA does not require employers to pay out unused PLAWA leave when employment ends. This is different from vacation pay — Illinois does require payout of accrued vacation under the Wage Payment and Collection Act. PLAWA leave and vacation leave have different payout rules, which is one reason many employers keep them in separate buckets.

What are the penalties for PLAWA violations?

Employers who violate PLAWA can face civil penalties of up to $2,500 per offense, plus damages to affected employees including back pay and attorney's fees. The Illinois Department of Labor enforces the law and can investigate complaints. Retaliation against employees who assert PLAWA rights is also prohibited and carries additional penalties.
