DETROIT (AP) -- A call to raise the minimum wage has returned in the run-up to Labor Day.
It's come in the form of worker rallies and a report finding Michigan ranks second-to-worst among states for wage growth during the past 30 years.
Fast-food workers in Detroit, Flint, Lansing and elsewhere protested Thursday demanding higher wages. They seek $15 an hour -- more than double the federal minimum wage of $7.25.
The nonprofit advocacy group Michigan League for Public Policy released a study a day later also calling for an increase. The report finds Michigan's median wage fell by 7 percent between 1982 and 2012 after adjusting for inflation -- the biggest wage drop of all 50 states after Alaska.
Critics say hiking the minimum wage would hurt employers' ability to hire.
