Do Not Create Office PoliticsThis manager pitted his people against one another. He told one person one thing that someone said and then told the other person the same thing. Office politics kill morale and as the manager you should be doing things to prevent it not perpetuate it. Dont be vindictive. Create a positive environment where people want to come to everyday.Do Not Lie and Be Mean to CustomersI caught this individual lying to customers on more than one occasion. Additionally, in a meeting with a CFO of a local company, he was so mean and rude that she actually threw the quote across the table at him. Then she kicked us out of her office, said she would NEVER do business with us, and told us to not come back. Yes, this was the low point of my career. It was truly an out of body experience.
