An effective leader is an active and willing listener. He or she will not cut another person off when speaking, but instead absorb what the person is communicating.
While kindness and generosity are taken for granted at times, these traits are essential in the workplace.
Effective leader communications include utilization of powerful "I" statements, such as, "I feel this company still has room for improvements." Avoid starting a sentence with the word "you" because it implies judgment.
