California voters will get the chance to raise the state's minimum wage to $15 an hour.

FOX's John Saucier reports:

The referendum would raise California's minimum wage by $5 an hour by 2021 and by $1 an hour over each of the next five years, a similar measure recently was approved in Oregon.

The current minimum wage in California is $10 an hour, many minimum wage workers would welcome passage, businesses and Governor Jerry Brown say such a steep wage increase would be too costly.

There's a chance the referendum could be preempted if the state legislature passes its own minimum wage measure.

The Service Employees International Union representing hospital workers drafted the referendum. It mirrors an effort to raise the federal minimum wage to $15, backed by both Hillary Clinton and Bernie Sanders.
