how did labor conditions change during ww1?

they worsened as fewer male workers were available
they changed because more factory jobs were available
they declined because union membership fell
they changed as more women joined the workforce

All of the options you listed are correct and contribute to the changes in labor conditions during WW1. Here are more detailed explanations:

1. They worsened as fewer male workers were available: During World War 1, a large number of men left their jobs to serve in the military. This led to a significant decrease in the available workforce, resulting in longer working hours, increased workloads, and intensified labor conditions for those who remained.

2. They changed because more factory jobs were available: With the increased demand for war-related goods and supplies, factories expanded their production. This created more job opportunities for those who were still part of the workforce. The higher demand for labor opened up employment options for many people.

3. They declined because union membership fell: As the war effort took precedence, labor unions faced challenges in maintaining their influence. Many union members left their jobs to join the military, resulting in a decrease in union membership. This decline weakened the bargaining power of workers, leading to a decrease in labor conditions.

4. They changed as more women joined the workforce: With a significant number of men joining the military, there was a pressing need to fill the vacant positions left behind. This led to an increase in female participation in the workforce. As women took on jobs previously held by men, labor conditions changed to accommodate the additional female workers. However, gender discrimination and pay disparities still existed, and women were often subjected to harsh working conditions.

Overall, labor conditions during WW1 were influenced by various factors such as the shortage of male workers, increased factory jobs, declining union membership, and the entry of more women into the workforce.
