> These jobs are not dehumanizing because of management. They are simply dehumanizing.
Nonsense. Helping people with their problems isn't dehumanising. Following a script that your company has optimized to avoid helping the person is dehumanising.
> Exactly what would you like to force people to do? What's this "attitude," and by what process does it dehumanize people who work in call centers? Do call center workers have material problems, or is this a question of abstract mindset or aesthetics?
You could make them fiduciaries for the people calling in, or something slightly less extreme. Call center workers have problems that are superficially material, but addressing them on a directly material level would just be playing whack-a-mole; the unpleasantness of the position stems directly from the incentives that those who control them are under.
