Following an increase in the California state minimum wage (with another coming in 2016), Los Angeles mayor Eric Garcetti has proposed raising the City's minimum wage by steps to $13.25 by 2017. San Francisco already has, and San Diego recently passed, a minimum wage ordinance that exceeds that required by California (which in turn exceeds the U.S. federal minimum). Employers must pay the highest of the wage rates where their employees work.
