Deadline to implement paid sick time under Missouri Prop A is April 15, 2025

Despite a pending legal challenge, the initial deadline under Missouri’s new earned paid sick time (PST) law is looming, and employers should begin preparing now. Proposition A, which amended Missouri’s minimum wage and overtime law, requires employers to provide PST to all employees working in Missouri, including part-time and temporary employees. By April 15, 2025, employers must provide notice to employees regarding their right to accrue and use PST, and employees must begin accruing PST by May 1, 2025.

Accrual of PST

Under Proposition A, employees must accrue PST at a rate of at least one hour for every 30 hours worked. Salaried employees who are exempt from the overtime requirements of the Fair Labor Standards Act (FLSA) are assumed to work 40 hours in each work week for purposes of PST accrual, unless their normal work week is less than 40 hours.

Under the statute, employees must receive PST based on cumulative hours worked, even if the hours are worked nonconsecutively or over the course of one or more weeks. As a result, even irregular, part-time employees who work brief shifts sporadically during the year are entitled to earn PST each time their total hours worked reach the 30-hour threshold.
