On a more serious note, that kind of work environment attracts people who don't give a sh** about the company's goals. Highly motivated people just don't need supervision on that level.
Whereas otherwise someone would apply to follow their dream career at a call center?
Of course they do, it's dead-end jobs, paying shit, that only people pressured to make ends meet ever apply to.
That's with monitoring or not.
And that's what makes monitoring both worse and applicable: because many of those people can't just quit...
Motivation is not what their employers are optimizing for, # of tickets solved / hour and # of upsells sold per day is.
