House Democrats are trying to generate support for changes to Michigan law related to wage discrimination against women.
One of the bills would create a statewide pay equity commission that would be responsible for developing definitions of comparable wages, which alarms some business groups.
The discussion about the Michigan legislation came on the eve of National Equal Pay Day, which is Tuesday.
The day is noted each April to indicate how much longer into a new year a woman must work to earn as much as a man earned in the previous year.
The latest US Census figures say that on average, a woman employed full-time and year-round earns about 77 cents for every dollar earned by a man.
