I will focus on women in the workplace in the 1930's. Approximately 24.3% of all the women in the country worked during this time.
Three out of every ten of these working women were in domestic or personal service. Of professional women three-quarters were school teachers or nurses.
On average, they worked very long hours and did not receive adequate pay. More than half of working women worked more than fifty hours per week. Women were entering the work force twice as fast as men were and the reason for this was the fact that they did not pay women as much money. Women were given better treatment if they were unionized.
Workers in the 1930s faced the economic realities of the Great Depression and 25% unemployment. Workers were expendable - easily replaced by any of the other hundreds of thousands of Americans looking for work. So wages went down, it was easier to get fired, work was more temporary in nature and had none of the insurance or benefits we have come to expect today.
Migrant agricultural workers came, not from foreign countries, but from economically devastated US states like Oklahoma and Arkansas. The migrants were white families looking for any way to make ends meet. Pay was low, working conditions were sometimes dangerous or difficult, and workers had no way to pressure their employers to improve those conditions.
