How did women's lives change once they started working?
There is no one way to answer this question, because the lives of women are very different. However, there are a few general statements that we can make. In light of this, let me say three things.
First, as women started working they found more independence. No longer were they completely financially dependent on their husbands or future husbands. They could live independently if they wanted to.
Second, many women also found that that their lives became more difficult, as many of them were also mothers. So, they had responsibilities at home and they also worked. Perhaps we can say that they were overworked.
Third, as women started working their future horizons opened up. They began to realize that they could do more and be more. Hence, there was a sense of liberation.
