As the debate over whether to raise Seattle's minimum wage to $15 an hour continues, a business coalition has launched its own public campaign.

Mayor Ed Murray has given his advisory committee a deadline of April 24 to present their proposal on the issue.

The group OneSeattle launched its public campaign this month. It's coalition of local small and medium-sized employers with the backing of the large business associations, like the Washington Restaurant Association.

They say they want to see the $15 minimum wage but they want a temporary training wage, a phase-in period, and the ability to count health care, commissions, tips and bonuses in total wages.
