The ERA is the Equal Rights Amendment, established to guarantee equal rights for women, especially when it came to wage differences between those of the opposite sex. The amendment seemed to fly smoothly until Phyllis Schlafly mobilized conservative women in opposition toward the act. She argued that the act would "disadvantage housewives", but there seemed to be more women for the act, than there were opposing it.
