Why is it important to smile? Body language-Even on the phone. Is it one of those days when the phone just won´t stop ringing? By call number four you still answer the phone with a friendly, polite “Good morning, how can I help you?” But four hours later, twenty calls later and you have lost your smile. So if that telephone rings one more time, don´t hang up, don´t scream “Yes!” at the poor caller. Take a deep breath and smile. I know the caller can´t see you, but a smile makes your voice sound friendly and polite, a smile makes you feel better and it makes your colleagues in the office feel better.
