Today, the minimum wage for California fast food workers will increase to $20 an hour, or 25% above the state’s $16 level. And a first-of-its-kind fast food council will give workers, employers and state government the opportunity to come together and set standards for the industry.

But rather than celebrating, many headlines are predicting mass layoffs, major burger price increases and even the end of fast food as we know it in California.

Whether someone prepares burgers, blends smoothies or tosses pizza dough, what determines which California fast food workers will be paid $20 an hour?

Assembly Bill 1228 is in effect as of Monday, setting wages for California fast food workers $4 above than statewide minimum. It also creates a Fast Food Council to determine future minimum wage increases and to establish other employment standards at fast food restaurants, according to the Department of Industrial Relations.

California Gov. Gavin Newsom’s higher minimum wage for fast-food workers takes effect Monday. On top of California’s already high $16 minimum wage, the minimum wage for fast-food workers will increase to $20 an hour, the highest minimum wage in the U.S.

Minimum-wage advocates parrot the claim that this is a win for fast-food workers. They cite a few studies to argue that those workers will earn more and suffer no job loss, and that poverty will fall. But a growing body of research demonstrates that the small number of studies advocates rely on are flawed.
