Missouri’s Proposition A, Mandating Paid Sick Leave, Went into Effect May 1, 2025

Missouri’s new paid sick leave statutory scheme, known as Proposition A, went into effect May 1, 2025. A last-ditch challenge to the law has failed, and the Missouri Supreme Court has upheld Proposition A and the election in which it was approved last fall. A brief, official summary of the Missouri Supreme Court’s opinion can be found here, and the full opinion can be found here.

Effective May 1, Proposition A raises Missouri’s minimum wage and mandates that most Missouri workers accrue paid sick leave. Key provisions include:

• Requiring most employers to provide paid sick leave, with workers earning one hour of leave for every 30 hours worked.
• Raising the minimum wage to $13.75 per hour in 2025 and $15 in 2026.
• Requiring employers to post a notice of these new rights in a specific form by April 15, 2025.

Proposition A imposes criminal penalties on employers who do not comply. It also allows individuals to sue employers for non-compliance and get certain statutory damages, as well as attorneys’ fees. For these reasons, all employers are encouraged to consult with their legal counsel to ensure that they are in compliance.
