When employees are proud of their work, they put extra effort into their actions. A good way to encourage this is by posting positive results in large print on a wall in the office, or perhaps a graph showing success stories, or even write on the wall above the employee entrance a powerful, positive phrase.
At Walt Disney World, the sign says, "Smile you are going on stage"
At Fairmont Hotels: "Here walk the greatest employees on earth"
At Ritz-Carlton: "Ladies and Gentlemen serving Ladies and Gentlemen"
... and at my old kickboxing gym, the sign read: "Kick Butt!"
Don't waste the white space - fill it with pride envoking words!
