The use of gadgets such as smartphones and other handheld devices may make employees more productive, but they haven't made the workplace more polite.

More than four in 10 (42 per cent) chief information officers (CIOs) interviewed have seen increased instances of poor workplace etiquette resulting from more frequent use of mobile electronic devices.

Five types of tech-etiquette offenders were identified.  Here are some tips to ensure that you don't fall into one of these categories:

1.  The Misguided Multi-tasker. This person thinks that e-mailing or
texting during a meeting or conversation demonstrates efficiency. But
others may regard it as a sign he prizes his BlackBerry more than the
company he keeps. Unless you want to create potential animosity at
work, use your handheld device only in an urgent situation and step
out of the room to reply.

2.  The E-mail Addict. If you've ever played e-mail tag with a colleague, you've likely encountered this person. She relies on a constant
stream of e-mails, instant messages or texts to communicate all of
her needs, often thinking it will save time. But excessive messaging,
particularly regarding trivial things, can be inefficient and
disruptive. Often a phone call or in-person discussion can resolve
issues more quickly.

3.  The Broadcaster. This person has no shame when it comes to his cell phone, using it anytime, anywhere - including open office halls and   the
public restroom - to discuss anything. When using your cell phone in
common areas, it's not only disrespectful but also potentially
 off-putting to others. Keep private conversations limited to private
 places.

4.  The Cyborg. Rare is the chance you see this person without the
blinking glow of a Bluetooth headset or iPod earbud nestled in her
 ear. Keeping a wireless earpiece or headphones constantly plugged in
 signals to others who may need to speak to you that your attention is
 not available. Show that you are accessible to your colleagues by
  using earpieces in the office with discretion and consideration for
 those around you.

5.  The Distractor. This person may have good intentions in setting his
phone to vibrate rather than torturing colleagues with a cheesy
ringtone, but hearing it repeatedly buzz loudly on a desktop or
during a meeting can be just as distracting. A better solution: Set
your phone to silent or keep it in your pocket.
