The battle for women’s equality in Britain gained momentum after the 50th anniversary of women’s suffrage in 1968. Inspired by workplace discrimination cases, Labour MP Joyce Butler led a years-long campaign that culminated in the Sex Discrimination Act of 1975, outlawing gender-based discrimination and creating the Equal Opportunities Commission.
