LANSING (AP) — Michigan’s Republican-led Senate passed bills Wednesday that would substantially scale back citizen-initiated minimum wage and paid sick leave laws that a business lobby criticized as too burdensome, setting up expected lawsuits if GOP Gov. Rick Snyder signs them into law before making way for a Democrat in January.

The Senate voted 26-12, almost entirely along party lines, to advance the two bills to the Republican-controlled House, which is expected to pass them and could vote as early as next week.

One measure would delay increasing the minimum wage to $12 an hour to at least 2030, instead of 2022. It would also repeal provisions to tie future increases to inflation and bring a lower wage for tipped employees in line with the wage for other workers. The current minimum wage is $9.25.

Another bill would exempt employers with fewer than 50 employees from having to provide paid sick time as required under the existing law that is scheduled to take effect in March, limit the amount of annual mandatory leave at larger businesses to 36 hours, instead of 72 hours, and make other changes.

To prevent the citizen initiatives from going to electorate earlier this month, where they would be much harder to change if voters had passed them, GOP legislators preemptively approved them in September so that they could alter them after the election with simple majority votes in each chamber.

Since the approval of the 1963 state constitution, lawmakers have adopted seven citizen initiatives but amended just one — and it was not in the same legislative session and came in response to a court ruling. Democrats and organizers of the ballot drives said making the changes this year, before Democratic Gov.-elect Gretchen Whitmer takes office, would be illegal.

“Gutting the One Fair Wage proposal after it was adopted is blatantly unconstitutional and will likely will lead to costly, time-consuming court challenges,” said Pete Vargas, campaign manager for the minimum wage ballot drive.

But Republican Senate Majority Leader Arlan Meekhof said the constitution does not prohibit lawmakers from amending the laws.

“We are doing what we believe is the best to keep Michigan’s economic engine going, providing a way for employers (and) employees to make their agreements together,” he said.

The minimum wage is scheduled to rise to $10 in 2019, $10.65 in 2020, $11.35 in 2021 and $12 in 2022, with yearly inflationary adjustments afterward. Under the legislation, the wage would increase to $9.48 in 2019 and by 23 cents annually until it hits $12 in 2030 — later if the unemployment rate is 8.5 percent or higher.
