Early Third Republic France was a time of dramatic social and economic change. With the tremendous growth of industrial capitalism in the last twenty years of the 19th century and the continued migration of workers to cities, the traditional system of meeting places for those seeking work was overtaxed. Skilled and unskilled trades alike had gradually developed systems to match those seeking work with employers, but the legalisation of trades unions in 1884, helped formalise these structures. Employers, too, were creating private labour placement offices.
