"The only thing 'free' about so-called free time is that it doesn't cost the boss anything. Free time is mostly devoted to getting ready for work, going to work, returning from work, and recovering from work. Free time is a euphemism for the peculiar way labor, as a factor of production, not only transports itself at its own expense to and from the workplace, but assumes primary responsibility for its own maintenance and repair. Coal and steel don't do that. Lathes and typewriters don't do that."
