re: FTC Calls For Data Privacy Laws
Unless you are using your "personal devices" from work, like a laptop on your employer's network, I don't see how this is an issue. If you are, then you are using your employer's internet access, most likely during work hours. If this is true, your employer has ever right to monitor your activity.
I'm really stumped by what you meant by "since the days of DOS". Unless you worked for a government organization back in those days, it is unlikely they were monitoring anything back then other than what you were accessing on a fileserver. That kind of monitoring put such a high load on servers from back then that most admins turned it off.
