Well, it's unfortunate that we have people like this who make employers feel the need to track their workers.
I would go further and assert that, in most cases, "people like this" probably aren't any, or are only a negligible part of the reason, only the excuse to allow them such tracking.
Just my general opinion, I have too little information to say if the tracking, in this case, is actually a rational and net-positive policy and not someone's power trip.
What reason do you think they have?
If you pay for butt-in-seat-hour then you have to track hours and butts. Either by newganled gps thingies of olden days methods of assigning a foreman to look at you.
