A majority of stuff mentioned in this article has to be outright illegal, if not borderline illegal when talking about privacy concerns. To get past it, they had to have put massive inclusions in their employee contracts and had employees sign off their entire existence to the company. It should also be noted that these happenings seem to all take place at sleazy, physical labor intensive companies. This isn't happening in any respectable sector I'd hope. I think the worst part is, is that these ideas are being created more and more by higher ups in companies and government who see no moral wrong in their plans. It doesn't affect them personally, but if it can be used in any way to further control a peon employee, then it's good for productivity. Even though it seems a bit like the article tries to defend this practice, there will never be a day on society where this is considered alright.

At the end of the day though, this is happening mostly to disposable workers who no on cares about. If one person complains about company overreach, well they can be replaced within 5 minutes. This is more something that lower income, down and out employees will have to worry about. This absolutely would not be tolerated to catch on to any respected industries/sectors. That's to not say physical labor workers aren't important, without them society would fall apart. It's that no one in authority typically cares about that type of worker and those employees concerns fall on deaf ears.
