A labor union may be defined as a continuous association of wage earners for the purpose of maintaining and improving the conditions of their employment. The character and causes of the development of unionism in the United States lay in economic and political causes, as the country was growing; the economic causes at work were the differentiation between the employing and working factions, the small business units, and the local markets. The causes of the first appearance of trade or labor unions were the development of a master working retailer and especially of the jobber and merchant middleman, a development made possible by the introduction of machinery, accumulation of capital, increase of population, and improvement of transportation with the consequent widening of the market--dividing the ranks of the craftsmen into two classes, masters and journeymen, i.e., establishing the wage system. Moreover, the government was controlled by the master class and faithfully defended the interests of the employers.
