Backers of a minimum wage hike in Michigan say they'll ask voters to approve increasing the rate to $9.50 an hour and eventually bringing tipped employees to the same rate. Frank Houston, treasurer of the Raise Michigan ballot committee, says proposed language for a ballot initiative will be given to the Secretary of State's office on Monday. Michigan's minimum wage is currently $7.40 an hour, slightly higher than the $7.25 federal minimum. Under the proposal, the state's minimum wage would increase by 50 cents in January 2015, and again six months later. The final $1.10 increase would occur in January 2016. The minimum wage for tipped employees is currently $2.65. That would increase 85 cents each year, starting in January 2015, until it reaches the minimum wage for other workers.
