Trust depends on openness, respect and humanity. Yet we often resist taking that approach in our professional lives, even though we know it would be absurd to do anything else in our personal lives.

Suppose I’m talking on my mobile phone when my wife calls. I can’t speak with her at the moment – I’m on deadline – so I say to her: “All of my brain is busy right now, so please hold and I’ll be with you shortly. Your call is very important to me.”

I guarantee that my customer satisfaction scores at home would suffer.

But if that’s true, why not re-craft the waiting message in our call centres so that it’s more like what we’d say to our spouses? “We know it’s frustrating to wait on hold – but we’re swamped right now answering other calls. We’ll get to you as soon as we can – probably about [insert an accurate number] minutes. We’re sorry for making you wait.”
