ST. PAUL, Minn. - The Minnesota Chamber of Commerce is suing the city of Minneapolis over its ordinance to raise the minimum wage to $15 by 2024.

The lawsuit filed Friday alleges that Minneapolis' ordinance conflicts with existing state law and asks the court to prevent its enforcement. Joining the Minnesota Chamber as co-plaintiffs are Graco Inc., the Minnesota Recruiting and Staffing Association and the TwinWest Chamber of Commerce.

Chamber president Doug Loon says a patchwork of local laws is burdensome, especially for employers with operations in multiple cities.

“Employers know what they have to pay to compete for a talented workforce and to deliver goods and services at a competitive price,” said Doug Loon, Minnesota chamber president. “A patchwork of local laws creates burdensome and time-consuming regulations on employers. They make it increasingly difficult for businesses to have a compensation system that works for employees and employer alike and hinder the creation of jobs.”

Minneapolis City Attorney Susan Segal told the Star Tribune the city will defend against the claims, which are similar to the chamber's challenge to Minneapolis' sick time ordinance. In that case, the court sided with the city but the chamber appealed.

Minnesota's minimum wage is $9.50 per hour and will go up to $9.65 on Jan. 1. Minneapolis' ordinance raises the minimum wage within the city to $10 per hour starting Jan. 1.
