Encourage those around you to be silly sometimes and let their goofiness out. It's good for business. Authentic, open communication creates credibility. Say what you see. It's probably the area managers ask me to help them with the most.
Honest feedback is what everyone wants and few people know how to give.
Adopt a philosophy that you want to help people. One of the best ways to do that is to tell them the truth about what is getting in their way. If you are diligent about sharing information with people about what is going on in the organization, your people will turn to you as the trusted source, instead of the grapevine. Curb your urge to be judgmental. We want those around us to be like us, think like us and act like us.
