Beyond that, at least in office work, you'll regularly see folks eating lunch at their desk and working through it even though by law they're supposed to be 'relieved of all duties'. This isn't because some supervisor said so but because they feel obligated to do so.

Most places I've worked given an hour by default as part of company policy. My point was that a lot of folks will choose to work through their lunch instead of taking a walk outside or relaxing a little.
I recall when one coworker hopped on the Soylent train. They had this whole plan that it would free up their lunch to go do other stuff like go for a bike ride, check out a museum, etc. They essentially ended up chugging the Soylent at their desk and working their entire lunch.
Maybe I'm old school but I don't like giving my labor away for free. Work will always be there.
In that case, tracking could actually be beneficial by making sure that nobody sacrifices their break time to improve their quotas. It doesn't have to be used for detrimental purposes (although it's probably unrealistic to assume that Amazon will be so benevolent).
