As David Rolf and Howard Wright told me just yesterday, they are hoping that City Council doesn’t tinker with the deal they brokered as co-chairs of the mayor’s minimum wage advisory committee. Their fear is that the whole thing would fall apart once even one change is made.

Yet while they say most of the people they know are on board with the deal, some are not. We’re not just talking Councilmember Kshama Sawant, one of only three people on the committee who didn’t sign on to the agreement.

Last night, the fiery and charasmatic activist Saru Jayaraman, director of the national Restaurant Opportunities Center United, strongly hinted that she was none too pleased with the deal. She was speaking at a Town Hall panel discussion on women and income inequality. In a room full of mostly women, Jayaraman decried minimum wage laws across the country that have exempted tipped restaurant workers, the majority of whom she says are women. She painted a dire picture of sexually-harassed workers, dependent for their income on pleasing their customers.

For years, she went on, Washington was one of the few exceptions to this sad state of affairs, due to a minimum wage that offered no tipped worker exemptions. And then she said this: “I hope and pray Seattle doesn’t move in the opposite direction.”

Does that mean what it sounds like? I called Jayaraman today to ask.

“Our stance is that it’s fabulous that workers are going to get a raise to $15,” said the Oakland resident, who also directs the Food Labor Research Center at the University of California, Berkeley. “Of course, that’s a wonderful, wonderful thing.”

But she said it was “very troubling” that Seattle was considering instituting a “lower wage for tipped workers.” The fact that the deal allows a credit for tips—as well as health care and other benefits—only temporarily (for up to 10 years, although employers have to meet the $15 mark in wages sooner) doesn’t appease Jayaraman, who said the period was too long.

“I’m not critical [of the deal],” Jayaraman maintained. “I’m actually asking City Council to do something.” Over the past few weeks, she says her group has brought local restaurant workers to City Hall. Their message: “Please don’t do this.”

Other people with different positions are surely lobbying City Council too. Whether Council members will be moved, given the delicate balance between business and labor interests worked out by the committee, is another question.
