Some tech junkies tend to neglect etiquette in the office. E-mail is still one of the leading culprits, but newer arrivals like BlackBerrys and wireless earpieces are causing their share of social snafus. "Technology should not be an opportunity to multitask conversations," says technology etiquette expert Laurie Puhn, president of Laurie Puhn Communications . "Anytime you're [doing that], it is rude and unacceptable."

The ability to instantly send and receive e-mails and messages on your BlackBerry, PDA or smartphone requires etiquette attention. Put that BlackBerry away during meetings to let others know you're giving your full attention to the proceedings. Cell phone related violations are a major source of complaints, whether it's ringers going off at inappropriate times, loud speaking voices or the inadvertent sharing of personal information with anyone in the vicinity. Just because your Bluetooth headset is unobtrusive doesn't mean you can interrupt someone you're speaking with to take a call. It's also polite to pull out your iPod headphones (both of them) when you're talking to a colleague.
