Women's role in the formation of trade unions and development of collective
bargaining, as well as in labor's historical struggle to improve day-to-da
y working conditions, has been conspicuously underplayed, if not ignored. Y
et, when one reviews the history of the reduction of working hours, prohibi
tion of child labor, elimination of homework in tenement slums, reform of f
actory legislation, and investigations into accidents precipitating early w
orkers' compensation legislation, the literature is rich with women's inves
tigative reports and studies on unhealthy and unsafe working conditions. Th
is was the case from the late 19th century in North America up until the 19
50s and the Cold War. The women's movement and political activities requiri
ng factory reforms then seemed to go underground, re-emerging in full force
during the 1960s. Women's involvement in the environmental movement, espec
ially in the United States, has been significant in politicizing occupation
al health as well. Their efforts led to the 1970 passage of the U.S. Occupa
tional Health and Safety Act.
