Introduction The global labor force has witnessed significant changes as far as women’s participation is concerned, as evidenced before during and after the Second World War. This is the case is mostly among married women. These changes have been occasioned by several factors of either a social, political or economic nature. Women’s participation in the First and Second World Wars led to changes in their social status as well as their working lives in different parts of the world and more so in those countries which were directly affected by the two wars. This paper seeks to analyze the demand and supply of married women in the labor force in the United States, before, during and after the Second World War, while at the same time giving the reasons, which led to these changes. Married Women’s Demand for and Supply of Labor Prior to the Second World War Kim (2003, para.1) states that before the onset of the war women were basically confined to household duty, which generally comprised of caring for the little ones, cooking, maintaining the backyard and washing up. It is important to note that women were judged mostly according to beauty and not according to their ability and talent. Nevertheless, he continues to add that as far as the 1880’s many were involved in industries like the textile industry, but excluded from the heavy industries. On the onset of the war (that in major way took up most of the male working force) the demand for human resource in the industries was eminent. On the other hand, the need for married women to continue putting food on their children’s table grew by the day. With this came the influx of women in the industries which were previously run by men. Kim continues to add that newspapers started writing more and more articles covering the topics on how women are achieving greater and greater heights in terms of tertiary education, and also gaining success in such fields as sports and other areas of society. An example quoted is that of an Argentinean woman who was hailed for her achievement in the field of civil engineering. It was evident that women had now replaced men in virtually most industries including heavy ones as was noted by a newspaper writing that noted that more than four thousand women had registered as workers in the Pennsylvania Railroad. Women at the time would work as nurses for the injured war soldiers while others worked on the farms that were left undone by the men who went to war. Others literally joined the industries most of which had been converted for ammunition manufacturing, so that the products would help out in the wars. If that was not all, a section of them helped in the war as spies. This was dangerous work for them but was one of the most effective ways of spying on the enemy (Kim, 2003, para.4). Demand for labor from the women who were left back home was high, and since the women had to provide a way in which to feed their young ones, the supply concurrently increased. Wilde (2010, para.5) explains that the main reason why the women joined the labor force was basically because of their patriotism for the country: that it was out of national duty, request by the government and thought out from their own conscience. These industries they joined pai
