"And, supposing you, as a German worker, don't like the way the "leader" of your factory runs things, and you want to find a job elsewhere... [W]e see a reversion to the practices of the Middle Ages, when the serf was not allowed to leave the service of the feudal lord. All through the [labour] laws... in fascist Germany runs this increasing... RESTRICTION OF FREEDOM TO MOVE ABOUT. Agricultural labourers are prevented from coming to work in the towns, and town workers from going to the country. There exists a system of compulsory labour... [T]he workers' freedom of movement is limited by the introduction of the Workers' Passport (Arheitsbuch)... [for] all workers earning less than 8,000 marks (about £650) per year. ...[O]nly highly paid administrative posts in industry...[were] above this figure. Fascist Party officials... are exempt... as are government officials. The police... inspect these passports at any time. Unsatisfactory entries... by the employer... particularly... referring to... political opinions, or showing... a "discontented" worker—practically debar him from... employment. So... however poor the conditions, he cannot risk leaving..."
