If you have your cell phone at work, it shouldn&#39;t ring. If you don&#39;t want to turn off your cell phone completely, at least set it to vibrate. The sounds of different ring tones going off all the time can be very annoying to others. In addition, you don&#39;t want your boss to know how often you get calls.If you have your cell phone at work, you should only use it for important calls. What should you classify as an important call? The school nurse calling to say your child is ill, your child calling to say he&#39;s arrived home from school safely, and family emergencies that you must deal with immediately are important. Your friend calling to chat, your child calling to say the dog had an accident, or your mom calling to tell you your cousin Tilly is engaged should not be considered important.While you are at work if you are in doubt about whether an incoming call is important, let voice mail pick it up. It will take much less time to check your messages than it will to answer the call and then tell the caller you can&#39;t talk.While it&#39;s okay to use your cell phone at work for private calls during breaks, don&#39;t stay at your desk. Find somewhere else to talk, where your conversation can&#39;t be overheard, even if what you&#39;re discussing isn&#39;t personal. You may be on a break but your co-workers have a job to do.This rule should apply to using your cell phone at work or anywhere. Why? Well, if you must ask — you never know who&#39;s in there; the person on the other end of the line will hear bathroom sounds, e.g., toilets flushing; it is an invasion of your co-workers&#39; privacy.In this day and age cell phones have become an essential work tool and therefore this rule should read &#34;Don&#39;t Bring Your Cell Phone to Meetings If You Are Going to Use It for Anything Not Related to the Meeting.&#34; It&#39;s likely you have your calendar on your phone and you probably use it to take notes. If you need to have it with you for those reasons, then you don&#39;t have much of a choice. Do not use it to text, read or post status updates, or play games. Don&#39;t bury your nose in your phone. Keep your eyes on whomever is speaking and stay engaged in the meeting. Doing anything else will be a clear signal to your boss that your mind isn&#39;t 100 percent on the business at hand.
