Great, so everyone hates the source, which is sometimes worthy of evaluation, but here are some other options reporting near to the same thing.
A law requiring large fast food chains in California to pay workers at least $20 an hour went into effect April 1. Two months later, how is it working?

California restaurant owners, including CEO of one of the largest El Pollo Loco franchises, explain how the new minimum wage is hurting business.

The reality, as in the reality away from the bubbles of California liberalism and to an extent MAGA Republicanism, is the very businesses that California targeted for wage increases run overall business models seeing anywhere from 3% to 6% profit margins. Sometimes more using multiple location franchise models but not really. Very slim means to cut into.
So any change in any aspect of cost, including labor cost, means an immediate decisions on number of people working, how long they work, what can be cut, and where prices can increase.
Unfortunately for the most vulnerable, California liberalism ignored economic reality and is now seeing various consequences ranging from layoffs, to location closes, to price increases from whoever is left standing, to a few going into bankruptcy and reorganization processes. And it happens to be exactly what various businesses and organizations said would happen.
Economics 101 guys, aggregate shifts that in this case resulted in less demand for the labor, higher prices to cover who is still employed, and less locations impacting the lot of it.
And we can see that California is going to double down, triple down, on the idea expanding the businesses impacted (as in sector and size) putting in place more minimum wage increases ignorantly expecting a different result.
This is why we can call it lazy progressivism. The expectation that one can force a single change into a business or area of the economy and assume every single other factor stays constant, which passes by absolutely no interpretation of economics whatsoever.
California did this to themselves, ended up with more inflationary pressures and killed a few jobs / businesses in the process. Well done!
