Therefore, truly effective leaders and/or managers surround themselves with a wide circle of people who are prepared to challenge them. They welcome healthy and constructive disagreement. They know that it is the way people learn. There is no place for sycophancy and ingratiation within this circle.
"It really isn't anybody's business how many people we have working for us. What's offensive is that I'm portrayed as this prima donna with these sycophants telling me how great I am all the time. Yes, they do work for me, but we're working together for a higher good". Demi Moore
I believe that sycophancy is the art of ingratiation through the simulation of motivation. The result is the poor engagement, low productivity and poor profitability in the business. Be careful!
