Where did migrant workers work?

Migrant workers do mostly menial labor in low-paying jobs. A large majority of migrants follow the planting season, traveling from state to state to harvesy crops, plant seeds, buck barley, etc.

Another large majority of migrant workers work menial jobs in all phases of construction. The workers are not unionized, so they are paid less than union workers despite experience or skills.

Because of the seasonal nature of harbesting crops, and construction, many migrant workers are unemployed for over half of the year, or find local temporary jobs. Some workers from Mexico return to their homes during the "off season".
