File -- In this May 1, 2014 file photo, Seattle City Council Member Kshama Sawant, right, looks on as Stephanie Sucasaca holds up a fist as Sawant had just done while interpreting Sawant's remarks into Spanish at a May Day rally in support of immigrant and workers rights and a boost in the minimum wage, in Seattle. While the Seattle mayor is proposing to raise the wage to $15 in the coming years to the highest level in the nation, some activists say that's too slow and are threatening to take the issue to voters with a ballot measure that would force a raise sooner.
