Nineteenth Amendment would be enough to ensure men and women were treated equally, and in 1921 the NWP announced plans to campaign for another amendment which would guarantee equal rights not limited to voting. The first draft of the Equal Rights Amendment, written by Paul and Crystal Eastman and first named "the Lucretia Mott Amendment", stated: "No political, civil, or legal disabilities or inequalities on account of sex or on account of marriage, unless applying equally to both sexes, shall exist within the United States or any territory subject to the jurisdiction thereof." Senator Charles Curtis brought it to Congress that year, but it did not make it to the floor for a vote. It was introduced in every congressional session from 1921 to 1971, usually not making it out of committee. The amendment did not have the full support of women's rights activists, and was opposed by Carrie Catt and the League of Women Voters. Whereas the NWP believed in total equality, even if that meant sacrificing benefits given to women through protective legislation, some groups like the Women's Joint Congressional Committee and the Women's Bureau believed the loss of benefits relating to safety regulations, working conditions, lunch breaks, maternity provisions, and other labor protections would outweigh what would be gained. Labor leaders like Alice Hamilton and Mary Anderson argued that it would set their efforts back and make sacrifices of what progress they had made. In response to these concerns, a provision known as "the Hayden rider" was added to the ERA to retain special labor protections for women, and passed the Senate in 1950 and 1953, but failed in the House. In 1958, President Eisenhower called on Congress to pass the amendment, but the Hayden rider was controversial, meeting with opposition from the NWP and others who felt it undermined its original purpose. The growing, productive women's movements of the 1960s and 1970s renewed support for the amendment. U.S. Representative Martha Griffiths of Michigan reintroduced it in 1971, leading to its approval by the House of Representatives that year. After it passed in the Senate on March 22, 1972, it went to state legislatures for ratification. Congress originally set a deadline of March 22, 1979, by which point at least 38 states needed to ratify the amendment. It reached 35 by 1977, with broad bipartisan support including both major political parties and Presidents Nixon, Ford, and Carter.
