They are the ones paying the bills. Don't take other people's supplies from their cubicles without asking first. Some may think that working in cubicles means you have complete sound barriers and thus enough isolation to be as loud as you like, but that is simply not the case. This should go without saying in the workplace. Ever wondered if there is such a thing as official etiquette for cubicles.

This is still wrong and unethical, it's against company policy, and you got it it's still against the law. Sound can in fact "bleed" over from one cube to the next, and this can be very disruptive not only to your coworker but also to clients.

Remember that if you take something that is not yours without asking yes, even at work (especially at work!) you are in fact stealing. No one will mind if you "steal" a paperclip or something of little monetary value. Here are a few guidelines that ought to be follo at your office, and if they're not, you might want to address this with your manager or with your employees and peers, if you are a supervisor yourself.

Keep voices down within the cubicles.
