Are you doing something that would make you worry if they were? 

They can track you pretty well just by using your computer.  I used to tell the noobs at Jones that they track every keystroke.  It wasn't far from the truth.  I used to be able to tell how many times an FA typed COMM, or any other communications screen command, and there was usually a direct correlation with how much money they made.  Now, I'm sure they track web usage, tool usage, etc to know what you're doing all day.    Security cameras might be the only thing they can do without your permission.  And those would more than likely only be pointed towards the public areas.
