• Prop 22 explained: how California voters could upend the gig economy

More than 40 years ago, Maria Cardona laid her livelihood on the line to demand change in the hot central California fields where she picked grapes and other produce for $1.75 per hour.

Cardona, now 80 years old, was tired of how farm workers like her were treated - the low wages, the backbreaking labor, the days without access to cold water or bathrooms. Most of all, she was tired of the disrespect from her bosses, who she said would regularly shout at workers in the field.
