"Employers who do this are being just as antisocial and psychopathic as this school district"

Because using rfid badges to unlock doors at an office building/control and log access to server rooms, etc is a psychopathic and antisocial thing to do

[betterunix]

Most uses of RFID badges for access control have nothing to do with building control or server rooms (and why would you want something as poorly secured as RFID when a smartcard would be equally convenient and far more secure?). Most uses of RFID are based on the same reasoning that leads to the installation of keystroke logging software, MITM devices, etc. -- the idea that employees should be watched at all times, and that the more detail you have about your employees work habits, the better (and you should never have know how to judge the products of their work; after all, that is not the job of a top-level manager).

As an information security professional, I am so glad we use RFID badges. I want to know who is getting into my secure datacenter and when, and be able to revoke that right with the click of a button if things start going pear-shaped with their activities.

...because as we all know, an RFID badge is so terribly difficult to clone.

RFID is a broad spectrum, not necessarily one technology. Some are more secure than others. Even with the most basic, though, it's pretty easy to clone a key or a keycode as well. Keys can't be revoked if you don't know where they are, and keycode changes require everyone to learn the new keycode. It's a game of give and take.
