Those 3 words are: "I don't care".
If the people that work for you stop caring about their work it has a direct impact on your business. It shows through their interactions with customers, with co-workers, it's reflected in their daily duties, and worse it can become infectious. If an "I don't care" attitude spreads throughout your team, and departments, it eventually becomes part of the company culture.
You don't even have to hear your employees say these 3 words, usually their attitude or expression, or body language will give it away. As Ralph Waldo Emerson said "What you do speaks so loud that I cannot hear what you say."
I care about all the work I've ever done, everywhere I've worked.
The morale of this story is that if you have employees that care, you'll never have to worry about the work they do.
