How do you show your co-workers the importance of communication in the workplace?

"I show my co-workers the importance of communication through my willingness to ask questions if I do not understand the first time. I do not pretend to know something to save face. By creating an environment where questions are encouraged, we increase communication greatly, and see a healthier safety record as a result."

"I show my co-workers the importance of communication in the workplace simply from leading by example. I set the tone and expectations for how we should communicate by utilizing all forms of written, verbal and interpersonal communications, early and often in the process."
