### **Update – July 2025**

Missouri’s paid sick leave law, which took effect on May 1, 2025, has now been officially **repealed**. Governor Mike Kehoe signed [HB 567](https://documents.house.mo.gov/billtracking/bills251/hlrbillspdf/1616H.05T.pdf) into law on July 10, 2025.

The repeal takes effect on **August 28, 2025**. Until then, Missouri employers are still required to comply with the existing law—including leave accrual, usage rights, and job protections.

Axcet HR Solutions is here to help you navigate this transition. [Read our latest post on what employers need to do before and after the repeal >>](https://blog.axcethr.com/missouri-paid-sick-leave-law-repealed)

### Original Post - April 2025

Missouri’s new Paid Sick and Safe Time Leave (PSL) law—approved by voters in November 2024 through Proposition A—is still scheduled to take effect on May 1, 2025.

That means employers must prepare now by updating leave policies and meeting posting requirements by April 15, as required by law, even as legal and legislative challenges continue.

[![Hubspot-CTA-Missouri-Min-Wage-_1400-x-732-px_ (1)](https://no-cache.hubspot.com/cta/default/2652187/interactive-192770004043.png)](https://blog.axcethr.com/hs/cta/wi/redirect?encryptedPayload=AVxigLKo3cbqnA0GTq57P%2Fx5D0eRax8FZQHoV8vOMGa%2FHTffkXoi0phCGBL5O9GEE%2F3bSUGMdsn7q7esJix7rJWE5zbs9BHfJ0h65n1tOKs8c9xIvyq6fZc4EhFKEo4lUia4t2rGhOvKIiuSh8R8EdXacmtn7vy%2Fs1Onjl4URHpRF5%2B1Y4pcT9rOsd9gtPsyrCk%2BkAw%3D&webInteractiveContentId=192770004043&portalId=2652187)

## The Fate of Missouri's Paid Sick and Safe Time Leave Law: Two Challenges

Two separate efforts could ultimately change or invalidate the law—either before or after its effective date.

### 1.  Pending Missouri Supreme Court Case (Case No. SC100876)

A lawsuit currently before the Missouri Supreme Court challenges the validity of Proposition A. Oral arguments were heard on March 12, 2025, and a decision is expected before May 1.

The legal challenge claims the measure violates several provisions of the Missouri Constitution, including:

- #### Single-Subject Rule

Proposition A combines minimum wage increases with paid sick leave in one ballot measure.

- #### Clear Title Requirement

The title allegedly does not express a single subject clearly.

- #### Misleading Summary Statement

The language voters saw is argued to be unfair or insufficient.

- #### Inadequate Fiscal Note Summary

The economic impact may have been misrepresented.

- #### Equal Protection Concerns

The law treats certain employers and workers differently without clear justification.

If the Court agrees with any of these claims, the law could be invalidated—at least temporarily—until revised and reapproved.

If the Court upholds the language, the law will continue as planned.

### 2.  Legislative Repeal Effort

On March 13, 2025, the Missouri House of Representatives passed legislation to repeal the paid sick leave provisions of Proposition A and modify the minimum wage increases. The bill is now in the Missouri Senate, where it was referred to the Committee on Fiscal Oversight on March 27.

- If passed and signed by the Governor, the repeal would take effect on August 28, 2025.
- This means the PSL law could go into effect on May 1, only to be rolled back later in the year.
- Legal challenges to any repeal could follow, but the repeal would be valid law unless overturned by the courts.

## What Employers Should Do Now

Until or unless the law is overturned, PSL remains the law of Missouri—and employers are required to comply by May 1. That includes:

- **Providing** the required employee notice by April 15, 2025, on 8.5” x 11” paper in 14-point font.
- **Posting** the state-provided workplace poster in a conspicuous location.
- **Updating** leave policies to meet accrual, usage, and documentation requirements.
- **Training** HR and managers on how to administer the new leave protections.

Axcet HR Solutions is closely monitoring both the legal and legislative developments. We’ll continue to provide timely updates—but for now, employers should stay the course and prepare to comply by May 1.

The Fate of Missouri's Paid Sick and Safe Time Leave Law: Two Challenges Two separate efforts could ultimately change or invalidate the law—either before or after its effective date. 1. Pending Missouri Supreme Court Case (Case No. SC100876) A lawsuit currently before the Missouri Supreme Court challenges the validity of Proposition A. Oral arguments were heard on March 12, 2025, and a decision is expected before May 1. The legal challenge claims the measure violates several provisions of the Missouri Constitution, including: Single-Subject Rule Proposition A combines minimum wage increases with paid sick leave in one ballot measure. Clear Title Requirement The title allegedly does not express a single subject clearly. Misleading Summary Statement The language voters saw is argued to be unfair or insufficient. Inadequate Fiscal Note Summary The economic impact may have been misrepresented. Equal Protection Concerns The law treats certain employers and workers differently without clear justification. If the Court agrees with any of these claims, the law could be invalidated—at least temporarily—until revised and reapproved. If the Court upholds the language, the law will continue as planned. 2. Legislative Repeal Effort On March 13, 2025, the Missouri House of Representatives passed legislation to repeal the paid sick leave provisions of Proposition A and modify the minimum wage increases. The bill is now in the Missouri Senate, where it was referred to the Committee on Fiscal Oversight on March 27. If passed and signed by the Governor, the repeal would take effect on August 28, 2025. This means the PSL law could go into effect on May 1, only to be rolled back later in the year. Legal challenges to any repeal could follow, but the repeal would be valid law unless overturned by the courts. What Employers Should Do Now Until or unless the law is overturned, PSL remains the law of Missouri—and employers are required to comply by May 1. That includes: Providing the required employee notice by April 15, 2025, on 8.5” x 11” paper in 14-point font. Posting the state-provided workplace poster in a conspicuous location. Updating leave policies to meet accrual, usage, and documentation requirements. Training HR and managers on how to administer the new leave protections. Axcet HR Solutions is closely monitoring both the legal and legislative developments. We’ll continue to provide timely updates—but for now, employers should stay the course and prepare to comply by May 1.",
