The California minimum wage is $6.75 an hour, but as any minimum wage worker in San Francisco can tell you, that won’t get you very far in one of the most expensive cities in the United States. In the spring of 2003, a group of community based organizations and individuals, including the Central City S.R.O. Collaborative, formed a coalition to put an initiative on the ballot that would raise the minimum wage in San Francisco to $8.50 an hour. The coalition gathered more than enough signatures to qualify Proposition L for the ballot, waged a citywide voter education and turnout campaign, and managed to pass the measure by a 20% margin on November 4, 2003.
