Participants in our training classes tell us stories of how they are treated over the phone and I agree no-one deserves to be interrupted, yelled at or disrespected.
My recommendation is to take the high road.
When you pick up the phone, build credibility and set the tone with helpful words and an upbeat voice.
How do you want to sound? Maybe calm and competent, or professional and pumped? You can do it!
Write down the words you'd like others to use when they describe you, post those words by the phone, sit up tall, read those words and say your greeting. Own it!
Don't let the day or the caller bring you down. Choose to set the tone with your tone.
