Read the excerpt from Fast Food Nation. “When management determines exactly how every task is to be done . . . and can impose its own rules about pace, output, quality, and technique,” the sociologist Robin Leidner has noted, “[it] makes workers increasingly interchangeable.” The management no longer depends upon the talents or skills of its workers — those things are built into the operating system and machines. Jobs that have been “de-skilled” can be filled cheaply. The need to retain any individual worker is greatly reduced by the ease with which he or she can be replaced.
