3. Always Say Excuse Me, Please, Thank You and I'm Sorry
These are just simple phrases, first taught to us by our parents to be good girls and good boys, which we should have mastered by this time.
Always say "excuse me" when you cough, when you sneeze, and when you call someone's attention in between their work or conversation.
Always say "please" when asking someone a favor. Without this, you will sound like you are demanding or giving command.
When people do things for you, whether it is a superior or a subordinate, you should always say, "Thank you." This will show your co-workers that you appreciate them and what they do for you and for the company.
Saying "I'm sorry" is such a powerful way of letting others know that you didn't mean what just happened, thus making the situation less disturbing or less disappointing. Saying "I'm sorry" is just an initial step because it should be followed with what you should do to make it up.
