What do the strikers want? Why do they think a strike will help them?

Springtime means that is time for the asparagus to be harvested, but this year it also means the resurgence of the strike, just as Marta had predicted. There are people holding signs all over the camp, urging everyone else to join the strike. They want better wages and working conditions. I don't think a strike will help them. Most of the workers are illegally in the United States and can be deported.
