The problem with "feel bad" motivation strategies is that they only really work in the short term. Sure, putting tracking devices on employees increases productivity right then, but after a few months, once the employees have figured out how to game the system (or realize that the data from these devices isn't being scrutinized, because performing that kind of rigorous data analysis is expensive/time consuming), productivity will drop right back to where it was before.

Or worse, because now they have easy metrics to justify their "work", and if they were invested personally in the company you can bet they aren't now. Now it is an us-vs-them situation where they feel justified by doing the bare minimum as long as they satisfy the tracking methods.
