This is the crux of it. Man wants to pay his workers a non livable wage and have them stay on-farm 7 days a week. That’s an unreasonable proposition. This law might be the wrong lever to pull, but the fundamental issue here is farm owners are trying to get people to do something without paying them fairly.
The solution, in my mind, is collective bargaining. Farm workers should group together and demand whatever would help them, and lawmakers should support them doing that - rather than a top-down approach that ends in whack-a-mole. There is no one little tweak from somebody who’s never picked a veggie in their life that’s going to fix this - empower and support the people to fix their own problems.
