Question

one way women used their positions in the workforce to demand rights was to join unions work longer hours vote for better representation

Explanation:

Unions are organizations that represent workers and advocate for their rights. By joining unions, women could collectively demand better working conditions, fair pay, and other rights. Working longer hours would not help in demanding rights; it might even be exploited. Voting for better representation is a political act not directly related to using workforce positions in the same way as union - membership.

Answer:

join unions
