Labor unions

"Labor unions are interest associations of workers in waged employment. They are formed to improve the market situation and the life chances of their members, by representing them in the labor market, at the workplace, and in the polity, and in particular by collectively regulating their members' terms of employment. Unions emerged in the transition to industrial society in the nineteenth century, together with the de-fedualization of work, the rise of free labor markets, and the commodification of labor. While employing modern means of formal organization, they represent an element of traditional collectivism in a market economy and society. Unions have taken a wide variety of forms and adopted different strategies in different historical periods, countries, and sectors. They are therefore favorite subjects of comparative social science." (excerpt
