Evidence

Page 482 Selected randomly from the company’s workforce of almost 35,000, they were each told of the interview shortly beforehand by their bosses, foremen or works representatives, and asked to come to the interview room, which was a separate room within the factory. In addition, fifty-five group discussions with a total of 539 participants were conducted by assistants of the Institute of Social Research, usually inside the factories. — Rolf Wiggershaus, The Frankfurt School, 508
