Washington residents could vote on minimum wage changes in November.
And a coalition of businesses will be one of the biggest opponents of the plan, Initiative 1433.
It would raise Washington's minimum wage by $4 -- to $13.50 an hour.
But the Washington Restaurant Association and other groups contend that a higher wage could lead employers to cut their staff levels.
Association President Anthony Anton also says the four year rollout would be too quick.
Anton says the state should consider different minimum wages for rural and urban areas.
For now, associations representing businesses, farmers and other industries have signed a statement opposing the initiative.
But supporters of the wage increase celebrated Wednesday.
They say they submitted enough petition signatures to get the measure on the ballot.
