JEFFERSON CITY, Mo. — The Missouri Supreme Court on Tuesday upheld a voter-approved ballot measure gradually raising the state's minimum wage to $15 an hour and requiring employers to provide paid sick leave to workers.
The court rejected claims from business groups that the initiative's ballot summary and cost estimate were misleading and thus amounted to an election irregularity that should invalidate the results.
Missouri voters approved Proposition A by nearly 58% in November.
The first step in the minimum wage increase — to $13.75 an hour — took effect in January. The minimum wage is to rise to $15 an hour in 2026, with annual inflationary adjustments in subsequent years.
The paid sick leave requirement is scheduled to take effect Thursday, though Republican state lawmakers are pushing legislation that would exempt smaller businesses and revise other details of the law.
Lawmakers in Nebraska and Alaska also are seeking to revise paid sick leave measures approved by voters last fall.
The Missouri Chamber of Commerce and Industry responded to Tuesday's court ruling by imploring lawmakers to act quickly to change the paid sick leave law.
''We believe business owners know best how to run their own companies, and additional mandates and government regulations do not promote job growth,'' chamber President and CEO Kara Corches said in a statement.
