You’d probably have to do a public records request with the Department of Industrial Relations to get an account of all the enforcement actions.
While I agree with your point about organizing and striking, California has some of the country’s most powerful unions and labor protections, even for non-union industries. For example, most software developers in CA can’t be classified as exempt if they’re paid under 115K and can sue for quite extensive damages in the event of misclassification:

This amount is also indexed to inflation and increases every year. This does not, however, prevent employers from posting jobs on HN below this amount, in contradiction to the law, which I’ve seen from time to time.
