WASHINGTON (AP) — Some supporters of a $15 minimum wage in the District of Columbia for workers who rely on tips aren't happy with a recent compromise on the issue.

Last week, the D.C. Council unanimously approved a $15 minimum wage starting in 2020. The bill also includes an increase to $5 an hour in base wages for workers who get most of their income from tips. As part of a compromise, advocates abandoned a plan to put a $15 minimum wage for everyone, including servers and bartenders, on the ballot in November.

But some supporters of changing the tipping system plan to file a new ballot initiative on Tuesday. They say all workers deserve a living wage, and they say the D.C. Council caved in to lobbying from deep-pocketed restaurant owners.
